摘要
文章针对广州市珠江流域溶岩发育的特点进行分析,对大坦沙岛电力隧道盾构始发工作井范围内的溶(土)洞采用袖阀管注浆技术,防止地下连续墙施工期间出现地面塌陷,确保地下连续墙墙体成型质量。
According to the characteristics of dissolved rock development in the Pearl River Basin in Guangzhou,this paper uses the sleeve valve tube grouting technology for the dissolution(soil)hole within the starting well of datansha Island power tunnel to prevent the ground collapse during the construction of the diaphragm wall and ensure the forming quality of the diaphragm wall.
