摘　　要：目前大部分深基础工程桩基施工项目采用旋挖钻机设备施工,但是对于大桩径、深桩使用市场,反循环钻机还是有着不可替代的作用。为适应大桩径、深桩施工,反循环钻机也逐步由汽车底盘发展为履带式底盘,主要发展方向有两类:一种是电机驱动动力头的反循环钻机,还有一种是由液压驱动动力头的液压式反循环钻机。液压式反循环钻机主要由钻杆、钻斗,行走履带底盘,上车装置,桅杆架,动力头,砂石泵系统,液压系统及电气系统组成。就反循环钻机液压系统进行分析探讨。At present,most of pile construction projects of deep foundation engineering adopt rotary drilling rig,but for large diameter pile and deep pile market,reverse circulation drilling rig still has an irreplaceable role.In order to adapt to construction of large diameter piles and deep piles,reverse circulation drilling rig has gradually developed from automobile chassis to crawler chassis.There are two main development directions:one is reverse circulation drilling rig with motor driven power head,and the other is hydraulic reverse circulation drilling rig with hydraulic driven power head.Hydraulic reverse circulation drilling rig is mainly composed of drill pipe,drilling bucket,walking crawler chassis,mounting device,mast frame,power head,gravel pump system,hydraulic system and electrical system.Hydraulic system of reverse circulation drilling rig is analyzed and discussed.
