摘要
珠三角城际轨道交通穗莞深2标太平隧道改扩挖施工中,暗挖隧道二衬围岩混凝土出现一定程度的渗漏,结合工程现场情况,对渗漏部位进行分析后,选用了化学灌浆材料对渗漏部位进行高压注浆,较好解决了暗挖施工中的防水难题。
During the construction of Taiping Tunnel of Shui-Guan-Shen 2 Section of Pearl River Delta Intercity Rail Transit, the second lining of concrete in the bored tunnel leaks. Combined with site conditions, high pressure grouting with chemical grouting materials are chosen for the leakage treatment after leakage spot analysis, which solves the problem of leakage in bored tunnel.
