液压抓斗和液压双轮铣槽机在防渗墙施工中的联合应用

摘要

Hydraulic grab is widely used in trench excavation in underground works.It is generally applicable to the case of lower depth and loose soil formation only.While hydraulic cutter can overcome the disadvantages of the hydraulic grab.The joint application of these two kinds of equipment in the construction of plastic concrete cut-off wall in Dam Complex of Upper Atbara Project ( DCUAP) is introduced, which ensures the smooth and timely completion of the whole project.The experiences are of great value to similar projects in the future.%介绍在苏丹上阿特巴拉水利枢纽项目塑性混凝土防渗墙施工中，采用液压抓斗、液压双轮铣槽机两种设备的联合施工技术，充分发挥各自的优势，保证整个防渗墙工程顺利完成。
