1 前言 D65PAB型推土机是一种特殊型式的湿地推土机,也是日本建设省和小松制作所20年合作历史至今众多开发项目中的又一新机型,主要用于水陆交接地带和浅海水下工程的推土与掘削作业。它和以前研制成功的大型湿地推土机D155W相比,更利于在土壤强度较低(圆锥测试指数小于500kP_a)的松软土质条件下工作。日本将其用于清理近海渔场的海底和水位不高的河床,可代替挖泥船和其他作业机械推移水下砂石和淤泥等,并可进行河道疏浚工作。 2 结构特点和性能如图1和图2所示,它是在普通D65P型推土机底盘上加高驾驶室和加装密封舱而成。
1 Introduction The D65PAB bulldozer is a special type of wetland bulldozer. It is also a new model in the 20-year cooperation history between the Japanese Ministry of Construction and the Komatsu Plant. It is mainly used in land and water transfer and shallow seawater projects. Dozing and digging operations. Compared with the large-scale wetland bulldozer D155W that has been successfully developed before, it is more conducive to work under soft soil conditions with low soil strength (cone test index less than 500kP_a). Japan used it to clean the seabed and the riverbed with low water level in offshore fisheries. It can replace dredgers and other operating machinery to displace underwater gravel and silt, and can also perform river dredging work. 2 Structural features and performance As shown in Fig. 1 and Fig. 2, it was built on the common D65P bulldozer chassis with an elevated cab and additional sealed tanks.
