Soil foundation pit steel pipe pile composite supporting structure and construction method
The invention relates to a soil foundation pit steel pipe pile composite supporting structure and a construction method. The soil foundation pit steel pipe pile composite supporting structure comprises a plurality of front-row steel pipe piles and a plurality of rear-row steel pipe piles, wherein the front-row steel pipe piles and the rear-row steel pipe piles are arranged in parallel; the top ends of the front-row steel pipe piles and the top ends of the rear-row steel pipe piles are in rigid connection through top beams; the bottom ends of the steel pipe piles are all arranged in a sealed manner; a plurality of grouting holes are evenly formed in a steel pipe pile body; barb protection structures with a certain length are arranged outside the grouting holes, the grouting quality is ensured, and the bonding strength of the steel pipe piles and soil is improved; and panel structures are fixedly arranged on the open sides (foundation pit excavation sides) of the plurality of front-row steel pipe piles. The soil foundation pit steel pipe pile composite supporting structure has the beneficial effects that the steel pipe piles can be recycled, and the soil foundation pit steel pipe pile composite supporting structure is a green and environment-friendly foundation pit supporting structure; through high-pressure grouting in the steel pipes, the shear strength of the soil between the piles is improved; the composite supporting structure is formed by the soil between the steel pipe piles and is similar to a reinforced gravity type retaining wall; and the cost and construction difficulty of soil foundation pit supporting are reduced, the construction period is shortened, and the reliability of a supporting structure system is improved.
本发明涉及一种土质基坑钢管桩复合支挡结构及施工方法，包括多个平行设置的前排钢管桩和后排钢管桩，所述前排钢管桩的顶端和排钢管桩的顶端通过顶梁刚性连接，钢管桩的底端均密封设置，钢管桩身体均匀设有多个注浆孔，注浆孔外设置一定长度的倒刺保护结构，确保压浆质量和增加钢管桩与土体粘结强度，多个所述前排钢管桩临空侧(基坑开挖侧)固定设有面板结构。本发明的有益效果是：钢管桩可以循环利用，是一种绿色环保基坑支护结构，通过钢管内高压注浆，提高了桩间土体的抗剪切强度，钢管桩与钢管桩间的土体形成复合支挡结构，类似加筋重力式挡土墙，降低了土质基坑支护的成本与施工难度，节约施工周期，提高了支护结构体系的可靠度。
