低空间落锤式液压自动打桩机的研究

Investigation into hydraulic automatic pile driver with low type frame and with drop hammer

本文介绍了一种新型低空间落锤式液压自动打桩机的工作原理及组成结构，阐述了液压系统的设计要点．给出了液压系统的工作原理图及动作循环表，列举了该打桩机的工程应用实例。该打桩机较好的克服了在旧房加高、建筑物纠偏扶正、建筑物地基加固等建筑腋工中低空间打桩的难题。

This paper introduces the operating principle and constituent structure of a new hydraulic automatic pile driver with low type frame and with drop hammer,describes the design of the hydraulic system,gives out the schematic diagram of oper ating principle and the table of operating cycle,and takes the actual examples of the pile driver in engineering application.
