Grooving construction method for rock-socketed ultra-deep underground diaphragm wall
The invention provides a grooving construction method for a rock-socketed ultra-deep underground diaphragm wall, and belongs to the field of rail transit engineering. The grooving construction method for the rock-socketed ultra-deep underground diaphragm wall comprises the specific steps of preparation before construction, guide wall construction, mud wall protection, grooving construction, labor organization, quality control, safety measures and environmental protection measures. The grooving construction method is suitable for ultra-deep underground diaphragm wall construction of complex stratums such as rock-socketed stratums and bedrock protruding stratums. The grooving construction method solves the problem that a conventional grooving process and equipment cannot be used for footage in deep foundation pit envelope construction, and the requirements for the construction progress and the grooving quality are met. The grooving construction process is combined with a grooving machine, a pneumatic down-the-hole hammer, a double-wheel mill, a bedrock pre-blasting method and other construction methods, and compared with a single process, the grooving construction method is wide in geological adaptation range and high in grooving efficiency.
本发明提供一种嵌岩超深地下连续墙成槽施工的方法，属于轨道交通工程领域，该嵌岩超深地下连续墙成槽施工的方法具体步骤为施工前准备，导墙施工，泥浆护壁，成槽施工，劳动力组织，质量控制，安全措施和环保措施。本发明工法适用于嵌岩、基岩凸起等复杂地层超深地下连续墙施工；本发明解决在深基坑围护结构施工中常规成槽工艺及设备无法进尺的问题，满足施工进度及成槽质量要求；本发明成槽施工过程组合采用成槽机、气动潜孔锤、双轮铣、基岩预爆破等施工方法，相比单一工艺，本工法地质适应范围广、成槽效率高。
