The invention discloses a full-recovery assembly type foundation pit supporting structure and a construction method thereof, relates to the technical field of geotechnical engineering foundation pit supporting, and aims to provide the full-recovery assembly type foundation pit supporting structure which not only can guarantee the safety in the deep foundation pit excavation process, but also can meet the economical efficiency. The structure comprises a steel pipe pile group and a profile steel enclosing purlin assembly, the steel pipe pile group comprises front and rear row steel pipe piles arranged on the two sides of a soil body respectively, and the front row steel pipe piles are close to the excavation side of a foundation pit; the profile steel enclosing purlin assembly comprises a plurality of profile steel enclosing purlins and angle steel brackets, the profile steel enclosing purlins are arranged on the two sides of the tops of the front-row and rear-row steel pipe piles correspondingly, and the angle steel brackets are welded to the bottoms of the profile steel enclosing purlins close to the excavation side of the foundation pit. A full-recovery assembly type foundation pit supporting structure form is adopted, the foundation pit supporting structure can be pulled out and recycled subsequently, the manufacturing cost is saved, and green construction is achieved. And moreover, the reliability of the supporting structure is improved, a waterproof curtain does not need to be additionally arranged for a foundation pit project with a water interception requirement, and the manufacturing cost is effectively reduced.
本发明的一种全回收装配式基坑支护结构及其施工方法，涉及岩土工程基坑支护技术领域，用于提供一种既能保证深基坑开挖过程中的安全性，又能满足经济性的全回收装配式基坑支护结构。它包括钢管桩组和型钢围檩组件，钢管桩组包括分别设置于土体两侧的前、后排钢管桩，前排钢管桩靠近基坑开挖一侧；型钢围檩组件包括若干型钢围檩以及角钢牛腿，型钢围檩分别设置于前、后排钢管桩顶部两侧，角钢牛腿焊接于靠近基坑开挖一侧的型钢围檩底部。采用全回收装配式基坑支护结构形式，后续可以拔出回收利用，节约了造价，实现了绿色施工。而且，提高了支护结构的可靠性，对于有截水要求的基坑工程无需再另设止水帷幕，有效的降低了造价。
