水力挖土是一门新兴的土方施工技术。随着农村生产责任制的推行,农村工副业生产的飞速发展,农村劳动力的大量转移,水力挖土的出现越来越受到人们的关注和欢迎。水力挖土的基本原理,主要是借助于高压水枪的喷嘴,喷出一股密实的高速水柱,切割、粉碎土体,使之崩解、湿化,拌和成泥浆和泥块混合液,再由泥浆泵通过输泥管道吸送到排泥区或堆土区筑堤、修路,连续完成挖、装、运,卸、密实等工序。在砂土和砂壤土工程上具有工效高、成本低、工程质量好的优点。水力挖土施工机械,主要由冲泥系统、输泥系统和配电系统三部分组成。冲泥系统有高
Hydraulic excavation is a new earthwork construction technology. With the implementation of the responsibility system for rural production, the rapid development of rural sideline and auxiliary industries, and the massive transfer of rural labor force, the emergence of hydraulic excavation has drawn more and more attention and welcome. Hydraulic excavation of the basic principles, mainly by means of high-pressure nozzle of the water gun, jet a dense high-speed water column, cutting, crushing soil, make it disintegrate, wet, mixed into mud and mud mixture, and then by The mud pump is sucked into the sludge discharge area or embankment area through roads for transporting mud, and roads are completed. The processes of digging, loading, transporting, unloading and compacting are completed continuously. In the sand and sandy loam engineering with high efficiency, low cost, good engineering quality advantages. Hydraulic excavation construction machinery, mainly by the mud system, mud system and power distribution system composed of three parts. Red mud system is high
