DCW 2.2 \u2014 Espalhador de Precis\u00e3o de Cal\/Cimento para Estabiliza\u00e7\u00e3o de Solos em Uma \u00danica Passagem<\/h2>\n

O Watanabe DCW 2.2 \u00e9 um espalhador de cal e cimento montado na frente do trator, projetado para funcionar em combina\u00e7\u00e3o direta com o espalhador montado na traseira. Estabilizador de solo THOR ST<\/a> for single-pass soil stabilization of rural roads and agricultural infrastructure. Mounted at the front of the CVT tractor, the DCW 2.2 distributes lime or cement binder uniformly across the road surface at a precisely controlled application rate \u2014 immediately ahead of the THOR ST’s rotor, which mills the binder-covered material to depth and mixes it with water in the same forward pass.<\/p>\n

The key operational advantage of the DCW 2.2 over conventional “bag-spread” or broadcast truck spreading methods is precision and uniformity. The binder application rate is controlled electronically from a display installed in the tractor cab \u2014 the operator adjusts the delivery rate based on forward speed to maintain the target kg\/m\u00b2 binder dosage regardless of speed variation. Two internal rollers provide selectable distribution width: 2-meter width for the standard road treatment pass, or two independent 1-meter sections for partial-width treatment on roads where one lane can remain open during construction.<\/p>\n

O sistema combinado de trator \u00fanico DCW 2.2 (dianteiro) + THOR ST (traseiro) elimina a necessidade de uma passagem separada de espalhamento de ligante antes da m\u00e1quina de estabiliza\u00e7\u00e3o \u2014 reduzindo o n\u00famero total de mobiliza\u00e7\u00f5es de equipamentos, a dura\u00e7\u00e3o total do projeto e o custo total de constru\u00e7\u00e3o de projetos de reabilita\u00e7\u00e3o de estradas rurais.<\/p>\n

Como funciona a DCW 2.2 \u2014 Dois rolos internos e controle eletr\u00f4nico de velocidade<\/h2>\n

The DCW 2.2’s binder hopper holds the powdered lime or cement that will be applied to the road surface. Two internal rotating rollers drive the binder from the hopper through the distribution mechanism and onto the road surface at the controlled application rate. The key advantage of the roller-drive distribution system over gravity-fed or auger-feed alternatives is its ability to deliver a consistent volumetric flow rate \u2014 providing uniform ground coverage regardless of small variations in binder particle size or bulk density.<\/p>\n

\"Espalhador<\/p>\n

 <\/p>\n

Rolo duplo \u2014 Sele\u00e7\u00e3o de largura de 1 m ou 2 m<\/h3>\n

The two internal rollers are independently controlled. When both rollers are active, binder is distributed across the full 2,140 mm working width \u2014 matching the THOR ST’s milling width for a fully uniform binder coverage before the stabilizer pass. When only one roller is active, binder is distributed across a 1-meter section only \u2014 allowing the operator to treat one lane while leaving the adjacent lane undisturbed. This is particularly useful on road sections where one-lane traffic must be maintained during construction, or where a partial-width re-treatment of a specific lane or shoulder section is needed without treating the full road width.<\/p>\n

Sistema de controle eletr\u00f4nico \u2014 Visor da cabine<\/h3>\n

O DCW 2.2 inclui seu pr\u00f3prio sistema de controle eletr\u00f4nico com um visor instalado na cabine do trator. O operador monitora e ajusta a taxa de aplica\u00e7\u00e3o do ligante a partir do visor da cabine sem precisar parar a m\u00e1quina \u2014 compensando a varia\u00e7\u00e3o da velocidade de avan\u00e7o para manter a dosagem de ligante desejada por metro quadrado. O sistema eletr\u00f4nico registra os dados reais de aplica\u00e7\u00e3o, fornecendo um hist\u00f3rico do projeto com a quantidade de ligante e a cobertura para fins de documenta\u00e7\u00e3o de garantia da qualidade. Essa \u00e9 uma vantagem significativa em rela\u00e7\u00e3o aos m\u00e9todos manuais de aplica\u00e7\u00e3o para projetos rodovi\u00e1rios financiados pelo governo que exigem registros documentados de controle de qualidade.<\/p>\n

Montagem frontal \u2014 Opera\u00e7\u00e3o combinada de passagem \u00fanica<\/h3>\n

The DCW 2.2 mounts at the tractor’s front three-point hitch \u2014 the only configuration that allows the binder to be distributed immediately ahead of the rear-mounted THOR ST stabilizer’s rotor in the same forward pass. The separation distance between the DCW 2.2 application point and the THOR ST rotor is the tractor wheelbase \u2014 typically 3\u20134 meters. This ensures the binder is spread uniformly before the rotor mixes it, but is not exposed to wind or rain disturbance for an extended period before incorporation. The single-tractor, front-plus-rear configuration is the most efficient soil stabilization setup available \u2014 one operator, one tractor pass, complete binder distribution and soil milling in one coordinated operation.<\/p>\n<\/div>\n

Principais Diferenciais do DCW 2.2 \u2014 Por que o Espalhador com Controle Eletr\u00f4nico Supera os M\u00e9todos Manuais<\/h2>\n
\n
\n

\u25a0 Versatilidade de aplica\u00e7\u00e3o \u2014 1 m ou 2 m<\/p>\n

Dois rolos internos independentes permitem a troca instant\u00e2nea entre a distribui\u00e7\u00e3o de ligante de 2 metros (largura total de trabalho) e 1 metro (faixa \u00fanica). Para trechos de estradas rurais coreanas onde o tr\u00e1fego precisa ser mantido em um \u00fanico sentido durante a constru\u00e7\u00e3o, o modo de 1 metro permite o tratamento de uma faixa por vez sem o fechamento total da via \u2014 reduzindo o transtorno para a comunidade e a responsabilidade da empreiteira por interrup\u00e7\u00f5es no acesso.<\/p>\n<\/div>\n

\n

\u25a0 Controle eletr\u00f4nico integrado<\/p>\n

O sistema de controle com tela na cabine permite que o operador monitore e ajuste a taxa de aplica\u00e7\u00e3o do ligante em tempo real, diretamente da cabine do trator. A taxa de aplica\u00e7\u00e3o pode ser definida para manter a dosagem alvo em kg\/m\u00b2, independentemente da varia\u00e7\u00e3o da velocidade de deslocamento \u2014 sem interrup\u00e7\u00f5es, sem paradas para ajustes manuais. O sistema fornece um registro da aplica\u00e7\u00e3o real para a documenta\u00e7\u00e3o de qualidade do projeto, requisito obrigat\u00f3rio para projetos formais de engenharia rodovi\u00e1ria.<\/p>\n<\/div>\n

\n

\u25a0 Opera\u00e7\u00e3o otimizada de passagem \u00fanica<\/p>\n

A distribui\u00e7\u00e3o frontal seguida imediatamente pela fresagem traseira com o equipamento THOR ST na mesma passada elimina a necessidade de uma passada separada para espalhar o ligante, exigida pelos m\u00e9todos convencionais de estabiliza\u00e7\u00e3o. A remo\u00e7\u00e3o de uma passada completa da sequ\u00eancia do projeto reduz o total de horas de equipamento, o consumo total de combust\u00edvel e o custo total do projeto \u2014 um impacto particularmente significativo em trechos rodovi\u00e1rios mais longos, onde a mobiliza\u00e7\u00e3o e a cobertura das passadas s\u00e3o os principais fatores de custo.<\/p>\n<\/div>\n

\n

\u25a0 Efici\u00eancia e economia versus m\u00e9todos manuais<\/p>\n

The conventional “bag-spread” method \u2014 manually placing bags of lime or cement and spreading with a brush rake \u2014 is both labour-intensive and inherently non-uniform. Uneven binder distribution produces uneven stabilization strength, which creates weak zones in the completed road base that fail at accelerated rates under traffic. The DCW 2.2’s mechanized uniform distribution eliminates this variability and reduces labour requirements to zero for the binder distribution step.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Reabilita\u00e7\u00e3o de estradas rurais com estabiliza\u00e7\u00e3o de cal ou cimento<\/h3>\n

A aplica\u00e7\u00e3o mais comum do DCW 2.2 no contexto coreano \u00e9 a distribui\u00e7\u00e3o de cal ou cimento para a estabiliza\u00e7\u00e3o in situ de estradas rurais deterioradas. A dosagem \u00e9 determinada pela classifica\u00e7\u00e3o do solo existente (testes de laborat\u00f3rio realizados antes da constru\u00e7\u00e3o) e pela resist\u00eancia \u00e0 compress\u00e3o uniaxial (UCS) desejada para a base estabilizada. As dosagens de cimento para materiais granulares t\u00edpicos de estradas rurais coreanas variam de aproximadamente 4 a 81 TP5T em peso seco; as dosagens de cal para solos argilosos variam de 3 a 61 TP5T. O DCW 2.2 distribui essas dosagens uniformemente na velocidade de trabalho \u2014 uma capacidade que a aplica\u00e7\u00e3o manual n\u00e3o consegue replicar de forma confi\u00e1vel em toda a extens\u00e3o da estrada.<\/p>\n

Melhoria da estrada de acesso \u00e0 fazenda na montanha<\/h3>\n

On mountain farm access roads in Gangwon-do and the Gyeongsang highlands, lime or cement stabilization converts compacted earth tracks into all-weather structural surfaces capable of supporting farm trucks and agricultural machinery year-round. The DCW 2.2’s 1m\/2m width flexibility is particularly valuable on narrow mountain access roads where the full 2,140 mm working width of the 2m setting may exceed the usable road surface width on the narrowest sections.<\/p>\n

\"Certifica\u00e7\u00f5es<\/div>\n
The DCW 2.2 is part of Watanabe’s complete soil stabilization system range, developed and manufactured at the company’s Castro, Paran\u00e1, Brazil facility since 1970. Watanabe’s experience in soil stabilization equipment covers the full process from binder distribution to rotor milling \u2014 the DCW 2.2 and THOR ST reflect the integration of these two steps into a coordinated single-operator, single-tractor workflow that has been validated over years of operational experience in Brazilian rural road rehabilitation programs.<\/span><\/div>\n<\/div>\n

Why Brazil’s Rural Road Experience Applies to Korea<\/h3>\n

Brazil operates one of the world’s largest networks of unsurfaced rural roads \u2014 several million kilometers of agricultural access, farm-to-market, and village connector roads across conditions ranging from tropical clay through granite highlands and coastal sandy soils. The DCW 2.2 was designed and refined in this environment \u2014 precisely the conditions that Korean \ub18d\uc5b4\ucd0c\ub3c4\ub85c rehabilitation projects present. The operational parameters (binder types, application rates, working widths), equipment robustness requirements, and logistics conditions that shaped the DCW 2.2’s design directly parallel Korean rural road project conditions.<\/p>\n

Estoque local e suporte t\u00e9cnico na Coreia<\/h3>\n

A Korea Watanabe mant\u00e9m o DCW 2.2 em estoque em Ansan-si, Gyeonggi-do, juntamente com o THOR ST, para entrega completa do sistema. O suporte t\u00e9cnico em coreano abrange a configura\u00e7\u00e3o do sistema (DCW 2.2 + THOR ST no trator CVT), orienta\u00e7\u00f5es sobre taxas de aplica\u00e7\u00e3o para diferentes tipos de solo e ligantes, e configura\u00e7\u00e3o do sistema de controle eletr\u00f4nico.

\n

Perguntas frequentes \u2014 DCW 2.2<\/h2>\n
\n
\n

O DCW 2.2 pode ser usado sem o estabilizador de solo THOR ST?<\/p>\n

Yes \u2014 the DCW 2.2 can operate as a standalone front-mounted binder spreader independently of the THOR ST. In this configuration, it distributes lime or cement as a pre-spreading pass before a stabilization machine (any brand) makes its mixing pass separately. However, the full operational efficiency of the DCW 2.2 is only realized when it works simultaneously with the rear-mounted THOR ST on the same tractor \u2014 the single-pass binder distribution + milling combination is the system’s primary design purpose. Using the DCW 2.2 standalone adds a separate spreading pass to the project workflow, which is more efficient than manual spreading but less efficient than the combined single-pass operation.<\/p>\n<\/div>\n

\n

Qual trator \u00e9 necess\u00e1rio para transportar simultaneamente o DCW 2.2 e o THOR ST?<\/p>\n

The combined configuration requires: (1) CVT tractor (mandatory for THOR ST operating speed range); (2) minimum 250 CV power (THOR ST PTO requirement); (3) front three-point hitch with minimum 1,300 Kg lifting capacity for DCW 2.2 at the front; (4) rear three-point hitch or drawbar for THOR ST at the rear; (5) adequate tractor ballasting for front-rear weight distribution with both implements attached. Total system weight on the tractor is significant \u2014 confirm with your tractor manufacturer or dealer that the front hitch capacity and tractor frame loading are within the tractor’s rated specification for combined front and rear implement attachment. European CVT tractors in the 250\u2013350 CV range (Fendt, New Holland, CLAAS, John Deere IVT) typically accommodate this configuration.<\/p>\n<\/div>\n

\n

What is the “mandatory weight” of 1,300 Kg?<\/p>\n

The 1,300 Kg mandatory weight is the minimum front-axle load required when the DCW 2.2 is front-mounted and loaded with binder. This front weight is necessary to maintain tractor steering control and prevent front-axle lift when the heavy rear-mounted THOR ST (5,300 Kg) is also attached and working. The 1,300 Kg front ballast is typically achieved by a combination of the DCW 2.2’s own weight (hopper weight + machine weight) and any additional front ballast weights on the tractor. Confirm the tractor’s specific front axle load with both implements attached before commissioning the combined system.<\/p>\n<\/div>\n

\n

Como \u00e9 calibrada a taxa de aplica\u00e7\u00e3o do fich\u00e1rio eletr\u00f4nico?<\/p>\n

The DCW 2.2 control system is calibrated during initial setup by running the spreader at a measured speed over a test area and collecting and weighing the output \u2014 the calibration factor is then entered into the cab display. Once calibrated, the system automatically adjusts the roller speed to maintain the target application rate as the tractor’s forward speed varies. A re-calibration check is recommended when changing binder type (lime vs. cement, different grades) since particle density and flow characteristics differ between binder types and can affect the relationship between roller speed and actual delivery rate.<\/p>\n<\/div>\n

\n

Quais s\u00e3o as taxas t\u00edpicas de aplica\u00e7\u00e3o de ligante para estabiliza\u00e7\u00e3o de estradas rurais na Coreia?<\/p>\n

As taxas de aplica\u00e7\u00e3o do ligante devem ser determinadas por meio de an\u00e1lises laboratoriais do material espec\u00edfico da estrada a ser estabilizado \u2014 n\u00e3o existe uma taxa universal. A t\u00edtulo de orienta\u00e7\u00e3o geral (n\u00e3o substituindo os ensaios laboratoriais): a estabiliza\u00e7\u00e3o com cimento de materiais granulares de base de estradas t\u00edpicos das zonas montanhosas da Coreia geralmente requer 4\u201381 TP5T de cimento em rela\u00e7\u00e3o ao peso seco do solo (aproximadamente 7\u201315 kg\/m\u00b2 a 100 mm de profundidade, dependendo da densidade do solo); a estabiliza\u00e7\u00e3o com cal de solos argilosos em zonas costeiras da Coreia geralmente requer 3\u201361 TP5T de cal em rela\u00e7\u00e3o ao peso seco. A taxa de aplica\u00e7\u00e3o definitiva para qualquer projeto deve ser confirmada por ensaios de compacta\u00e7\u00e3o Proctor e de resist\u00eancia \u00e0 compress\u00e3o uniaxial (UCS) de misturas de solo + ligante espec\u00edficas do local antes do in\u00edcio do projeto. A Korea Watanabe pode recomendar laborat\u00f3rios geot\u00e9cnicos locais para ensaios de projeto de estabiliza\u00e7\u00e3o de solos.<\/p>\n<\/div>\n

\n

Qual \u00e9 a capacidade do reservat\u00f3rio e com que frequ\u00eancia ele precisa ser reabastecido?<\/p>\n

A capacidade da tremonha do DCW 2.2 e a frequ\u00eancia de reabastecimento dependem da taxa de aplica\u00e7\u00e3o do ligante e da velocidade de trabalho. Entre em contato conosco com os par\u00e2metros do seu projeto (tipo de ligante, taxa de aplica\u00e7\u00e3o desejada, largura da via e velocidade de trabalho) e forneceremos a capacidade espec\u00edfica da tremonha e o intervalo estimado de reabastecimento para a configura\u00e7\u00e3o do seu projeto. O planejamento da log\u00edstica de fornecimento de ligante \u2014 cronograma de entrega a granel, armazenamento no local e organiza\u00e7\u00e3o do carregamento \u2014 \u00e9 uma parte importante da prepara\u00e7\u00e3o de projetos para contratos de estabiliza\u00e7\u00e3o de solos.<\/p>\n<\/div>\n

Existe o risco de a poeira de cal\/cimento afetar moradores ou planta\u00e7\u00f5es pr\u00f3ximas?<\/p>\n

Lime and cement powder spreaders generate airborne dust during operation \u2014 a real concern for nearby residents, crops, and water bodies. The DCW 2.2 is designed to minimize dust by distributing binder at low height through the roller mechanism rather than broadcasting from height. In addition, the THOR ST’s water injection system immediately behind the DCW 2.2 introduces moisture that suppresses dust from the freshly spread binder within seconds of application. For projects near sensitive receptors (residences, orchards, water bodies), work during low-wind conditions and inform nearby residents in advance. The Korean government’s Construction Noise and Dust Management Guidelines (\uac74\uc124\uacf5\uc0ac \uc18c\uc74c\u00b7\uc9c4\ub3d9 \uad00\ub9ac\uae30\uc900) provide the regulatory framework for dust management on construction projects.<\/p>\n<\/div>\n

Que tipo de manuten\u00e7\u00e3o o DCW 2.2 requer ap\u00f3s cada projeto?<\/p>\n

Ap\u00f3s cada projeto: esvazie completamente a tremonha \u2014 res\u00edduos de cal ou cimento absorvem umidade e endurecem, obstruindo o mecanismo dos rolos. Limpe cuidadosamente o interior da tremonha, os rolos e o mecanismo de distribui\u00e7\u00e3o com ar comprimido e escova \u2014 n\u00e3o utilize \u00e1gua nos componentes internos (cimento + \u00e1gua = rea\u00e7\u00e3o de endurecimento). Inspecione as superf\u00edcies dos rolos quanto a desgaste e dep\u00f3sitos. Verifique o visor do controle eletr\u00f4nico e as conex\u00f5es dos cabos. Lubrifique todos os pontos de lubrifica\u00e7\u00e3o conforme o cronograma de manuten\u00e7\u00e3o. O problema mais comum de manuten\u00e7\u00e3o em equipamentos de distribui\u00e7\u00e3o \u00e9 o endurecimento de res\u00edduos de aglomerante no mecanismo de distribui\u00e7\u00e3o devido \u00e0 limpeza incompleta ap\u00f3s o uso \u2014 evite isso realizando uma limpeza completa ao final de cada dia de trabalho e antes de qualquer per\u00edodo prolongado de armazenamento.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

“Running the DCW 2.2 + THOR ST combined system on the Jecheon county road contract. The electronic cab control on the DCW 2.2 is genuinely useful \u2014 I can maintain the target cement dosage rate precisely even when I have to slow down for road furniture or narrow sections. The uniformity of the binder distribution compared to the bag-spread we used to do is obvious in the finished base strength results.”<\/p>\n<\/div>\n

“The 1m\/2m width switching was unexpected but very valuable in practice. On one road section in Gangwon, we had a drainage channel on one side that restricted the usable road width. 1m mode let us treat the full road in two passes \u2014 left half, then right half \u2014 without the DCW 2.2 spreading outside the road area. The THOR ST was full width both times but the binder coverage was exactly where it needed to be.”<\/p>\n<\/div>\n

“Lime stabilization on South Jeolla clay soils \u2014 the DCW 2.2 electronic control let us hit the 4.5% lime dosage rate consistently across the full project length. Previous projects using bag-spread had variable quality because manual spreading inevitably produces uneven coverage. The supervised quality control testing on this project accepted all sections on first pass.”<\/p>\n<\/div>\n

\u2605\u2605\u2605\u2605\u2605<\/p>\n

“Timber road stabilization \u2014 the DCW 2.2 + THOR ST single-pass operation means we complete a 200m forest road section per day with one tractor operator. The alternative with bag-spread would need a separate crew for spreading and a separate machine for the milling pass. The labour cost saving is significant on remote forest road projects where getting additional workers to site is difficult.”<\/p>\n<\/div>\n

“As the supervising engineer on the Boryeong stabilization project, the DCW 2.2’s electronic application records were what we needed for the quality assurance documentation. The dosage log from the cab control system showed consistent binder application rate across the full 6 km project length. This kind of verifiable quality record is increasingly required on government road contracts and the DCW 2.2 provides it automatically.”<\/p>\n<\/div>\n

“Internal plantation road stabilization \u2014 the DCW 2.2 + THOR ST system from Korea Watanabe was the right choice for our internal road network. The Korea Watanabe team provided application rate guidance before we started based on our soil type, which avoided the trial-and-error dosage adjustment that can waste binder and delay results. Maintenance advice after the first project was also practical and useful.”<\/p>\n<\/div>\n<\/div>\n<\/div>\n
