Device for improving vertical bearing capacity of tubular pile and construction method thereof
The invention discloses a device for improving the vertical bearing capacity of a tubular pile and a construction method thereof, and belongs to the field of solar power generation. The device comprises a pushing and pressing component, a reinforcement component, a positioning frame, a limiting steel ring and a slurry storage bag; a main body of the pushing and pressing part is a pushing and pressing steel pipe, transverse limiting stoppers are fixed to the outer wall of the pushing and pressing steel pipe at intervals, porous steel pipes with square openings serve as a main body of the reinforced part, the porous steel pipes are hinged through connecting bolts fixed to steel sleeves, and limiting steel rings are embedded into the inner wall of the pile end of the pipe pile. The lower end of the pushing and pressing steel pipe is connected with the reinforced part, and the slurry storage bag is arranged at the lower end of the pushing and pressing part and used for providing slurry for the porous steel pipe; the positioning frame is arranged at the lower end of the porous steel pipe; the positioning frame is temporarily fixed to the porous steel pipe through a rubber ferrule. The interaction force between the pile end of the pipe pile and the surrounding soil body is increased, the vertical compression resistance and uplift bearing capacity of the pipe pile is improved, the pile foundation work amount can be reduced, and meanwhile the vertical bearing capacity of the existing pipe pile can be rapidly improved.
本发明公开一种提高管桩竖向承载力的装置及其施工方法，属于太阳能发电领域，该装置包括推压部件、加筋部件、定位架、限位钢圈及贮浆袋；所述推压部件的主体为推压钢管，推压钢管外壁间隔固定横向限位器，所述加筋部件以上方开口的多孔钢管为主体，各多孔钢管通过钢制套筒上固定的连接栓铰接，所述限位钢圈内嵌于管桩桩端内壁；所述推压钢管的下端与所述加筋部件连接，所述贮浆袋设置在所述推压部件下端部，用于给多孔钢管提供浆液；定位架设置在多孔钢管下端部；定位架采用橡胶套圈与多孔钢管临时固定。本发明增加了管桩桩端与周边土体的相互作用力，提高了管桩的竖向抗压及抗拔承载力，可降低桩基工程量，同时可快速提高既有管桩的竖向承载力。
