Soil Nailing and Template for the Basement Exterior Wall Waterproof Construction Technology

摘要

For soil nailing armor for outdoor mold technology principle, construction technology of underground practice and the key parts operation are introduced. Through economic analysis, the author points out that this construction method is simple and easy to operate and the waterproof effect and quality can be assured. When soil nailing support is used for foundation pit retaining wall in the basement waterproof construction, the soil nailing retaining wall can be directly made the basement exterior template. If reasonable waterproof coiled material and scientific organization are chosen, earthwork of digging and filling can be reduced. When there is less land for construction, it can save mode branch recruitment. It can complete construction ahead of time and reduce project cost. Especially when the construction site is narrow and time is limited, this scheme can receive significant economic effect. This construction method is simple and easy to operate, it can simplify the construction process, speed up the construction progress. It can also save time, save the materials and machinery etc. and waterproof effect and quality can be guaranteed. It is worth popularization and application.
