Combined anti-slide pile and construction method
The invention discloses a combined anti-slide pile which comprises a plurality of groups of combined bodies of reinforcing steel bars and steel corrugated pipes, wherein the combined bodies are distributed in a matrix manner; each combination of the reinforcing steel bars and the steel corrugated pipes comprises the steel corrugated pipes, corrugated pipe sealing covers, threaded reinforcing steel bars and grouting hoses. The steel corrugated pipe is inserted into the drill hole, and a plurality of secondary grouting holes are formed in the pipe wall of the steel corrugated pipe; the twisted steel is fixedly mounted in the steel corrugated pipe; and the corrugated pipe sealing cover can seal the top opening of the steel corrugated pipe. According to the combined anti-slide pile, primary grouting can be carried out on the gap between the steel corrugated pipe and the drill hole through the grouting soft pipe, and after the primary grouting is finished, secondary grouting is carried out through the steel corrugated pipe; and after a plurality of groups of combination bodies of the matrix-type distributed steel bars and the steel corrugated pipes are constructed, the whole body can be equivalent to a large-section slide-resistant pile structure. The combined anti-slide pile has the remarkable advantages of small disturbance to the surrounding environment, high construction safety, high operation speed and the like, and is particularly suitable for emergency treatment of small and medium-sized landslides in traffic engineering.
本发明公开了一种组合体抗滑桩，包括若干组呈矩阵式分布的钢筋与钢波纹管的组合体；每组钢筋与钢波纹管的组合体均包括钢波纹管、波纹管封口盖、螺纹钢筋和注浆软管；钢波纹管插入钻孔，其管壁上设有若干二次注浆孔；螺纹钢筋固定安装于钢波纹管内；波纹管封口盖能够对钢波纹管的顶部开口进行封闭。该组合体抗滑桩通过注浆软能够向钢波纹管与钻孔之间的间隙内进行一次注浆，一次注浆结束后，通过钢波纹管进行二次注浆；当多组矩阵式分布钢筋与钢波纹管的组合体均完成施工后，整体即可等效为一个大断面抗滑桩结构。该组合体抗滑桩对周边环境扰动小、施工安全性高、作业速度快等显著优点，特别适用于交通工程的中小型滑坡应急处治。
