Novel miniature concrete-filled steel tube pile structure and construction method thereof
The invention discloses a novel miniature concrete-filled steel tube pile structure and a construction method thereof. The novel miniature concrete-filled steel tube pile structure comprises a concrete tube pile, an isolation sleeve and a steel tube system structure, and the steel tube system structure is mainly composed of a stress steel tube, a limiting supporting rod, a limiting steel plate and other components. And the isolation sleeve is located between the concrete pipe pile and the steel pipe system structure and used for isolating the concrete from the steel pipe. The stress steel pipe and the concrete pipe pile are restrained by the limiting steel plate and the limiting supporting rod, and the stress steel pipe is tightly attached to the isolation sleeve, so that the stress steel pipe and the concrete pipe pile are stressed together. And the limiting supporting rod is an important restraining part of the steel pipe system structure, is located in the supporting rod cabin and is expanded and contracted through the pulling and pressing rod. The construction method of the novel miniature steel pipe concrete pile structure is simple, during use, the limiting supporting rods are firmly supported at the bottom ends of the concrete pipe piles, after foundation pit construction is completed, the limiting supporting rods are retracted into the supporting rod cabins, and the steel pipe system structure is pulled out for reutilization.
本发明公开了一种新型的微型钢管混凝土桩结构及其施工方法，包括：混凝土管桩、隔离套管、钢管体系结构，其中钢管体系结构主要由受力钢管、限位支撑杆、限制钢板等构件组成。隔离套管，位于混凝土管桩与钢管体系结构之间，用于隔离混凝土与钢管。受力钢管与混凝土管桩由限位钢板和限位支撑杆约束，且受力钢管与隔离套管密贴，有利于受力钢管与混凝土管桩共同受力。限位支撑杆，为钢管体系结构的重要约束部件，位于支撑杆舱内，通过拉压杆实现展开与收缩。新型的微型钢管混凝土桩结构施工方法简单，使用时，限位支撑杆牢固地支撑在混凝土管桩底端，待基坑施工完成后，限位支撑杆收缩至支撑杆舱内，拔出钢管体系结构，进行重复利用。
