摘要
北京市通州区某新区综合管廊工程近距离暗挖下穿玉带河大街及现况热力方沟,施工中采取深孔注浆止水及加固土体、超前地质探测、初支快速封闭、初支背后回填注浆及动态监控测量等技术,减少了对热力方沟的扰动,将沉降控制在允许范围内,保障了热力方沟的安全运行。
There are series of technical measures adopted in the process of pipeline colligate alures passing through under existing thermal square ditch, include deep hole grouting to stop water and reinforce soil, advanced geological exploration, initial support structure fast sealing, initial support structure backfilling grouting and dynamic monitoring measurement etc. These series of technical measures reduced the disturbance of the construction to the thermal square ditch, control the settlement within the allowable range. It ensures the safe operation of the thermal square ditch.
