Microorganism double-row steel sheet pile foundation pit supporting structure
The invention discloses a microorganism double-row steel sheet pile foundation pit supporting structure which mainly comprises a front-row steel sheet pile wall, a rear-row steel sheet pile wall and a microorganism sand wall arranged between the front-row steel sheet pile wall and the rear-row steel sheet pile wall in a filling mode. The steel sheet pile is composed of a U-shaped steel sheet; according to the microbial sand wall, microbial bacterial liquid permeates into sandy soil, and calcium carbonate is induced by microorganisms to generate precipitation reaction, so that the microbial sand wall is formed. According to the scheme, the double-row steel sheet pile walls are adopted to form a good space structure, microorganism sand wall reinforcing construction is carried out after construction of the double-row steel sheet pile walls is completed, horizontal lateral displacement can be reduced, the top and the bottom of the pile can be evenly stressed, and it is guaranteed that the safety of surrounding buildings cannot be affected due to deformation in the excavation process of the foundation pit. The method further has the advantages of being not affected by environment and site limitation, small in foundation pit plane occupancy rate and easy to operate.
本发明公开了一种微生物双排钢板桩基坑支护结构，其主要包括：前排钢板桩墙、后排钢板桩墙、以及填充在前排钢板桩墙与后排钢板桩墙之间的微生物砂墙；所述钢板桩由U型钢板构成；所述微生物砂墙由微生物菌液渗透到砂土中，利用微生物诱导碳酸钙产生沉淀反应，从而形成微生物砂墙。本方案采用双排钢板桩墙形成较好的空间结构，在双排钢板桩墙施工完成后进行微生物砂墙加固施工，不仅能减小水平侧移还能使桩的顶部与底部受力均匀，保证基坑在开挖过程中不会因变形而影响到周围建筑物的安全。本发明还具有不受环境及场地限制的影响，且基坑平面占用率小及操作简单的优点。
