Foundation pit waterproof curtain and construction method thereof
The invention discloses a foundation pit waterproof curtain and a construction method thereof, relates to the technical field of foundation pit construction, and aims at solving the technical problemsthat in the prior art, a waterproof curtain is poor in waterproof effect, low in structural strength and prone to influencing the stability of an adjacent existing building. The key points of the technical scheme are as follows: the foundation pit waterproof curtain comprises a steel plate die, forming steel columns, a plurality of first pile holes, second pile holes located between the adjacentfirst pile holes and reinforcement cages located in the second pile holes; grouting holes and two forming holes are formed in the side wall of the steel plate die, and the forming steel columns penetrate through the forming holes and extend into the first pile holes; slurry is poured into the first pile holes through the grouting holes to form grouting column piles, first water stop pieces are arranged on the side walls of the reinforcement cages, second water stop pieces are installed on the side walls of the forming steel columns, and occlusion spaces are formed in the two sides of each grouting column pile; and the slurry is poured into the second pile holes to form reinforcement piles, and the reinforcement piles and the grouting column piles are occluded with each other. The waterproof curtain has a good waterproof effect and can stably support a foundation pit.
本发明公开了一种基坑止水帷幕及其施工方法，其涉及基坑施工的技术领域，旨在解决现有技术中的止水帷幕，止水效果差，结构强度低，易对紧邻既有建筑的稳定性造成影响的技术问题，其技术方案要点包括钢板模、成型钢柱、若干第一桩孔、位于相邻第一桩孔之间的第二桩孔以及位于第二桩孔内的钢筋笼，钢板模的侧壁设有灌浆孔以及两个成型孔，成型钢柱穿过成型孔并伸入第一桩孔内，通过灌浆孔对第一桩孔内灌注浆料并形成灌柱桩，钢筋笼的侧壁设有第一止水件，成型钢柱的侧壁安装有第二止水件，灌柱桩的两侧设有咬合空间，通过将第二桩孔内灌注浆料形成钢筋桩，钢筋桩和灌柱桩相互咬合；该止水帷幕具有良好的止水效果，可对基坑稳定支护。
