| 摘 要： | 液压抓头及冲击钻是大型地连墙施工的主要装备,但在海外工程中,往往受到当地施工设备不足等因素的制约,难以满足需要。在仅有2台回转钻、1台冲击钻以及泥浆净化机等有限设备资源的情况下,结合当地现有资源条件,通过进行技术革新,探索地连墙施工新的工艺装备,来满足纯海水环境中沙层地连墙施工的需要。

| Abstract: | The hydraulic grab head and impact drill are the main equipment for large underground continuous wall construction,but in overseas engineering,because of the lack of local construction equipment and other constraints,it is difficult to meet the needs.With limited equipment resources,i.e.only two rotary drills,one impact drill and mud purification machine,we explore the new technology of underground continuous wall construction considering the local existing resource and by the technological innovation,to meet the needs of the underground continuous wall construction in the pure seawater environment. |
