PC construction method pile for soft soil stratum and construction technology of PC construction method pile
The invention relates to the field of building construction, in particular to a PC construction method pile for a soft soil stratum and a construction technology thereof.The PC construction method pile comprises a steel sheet pile and a steel pipe pile which are sequentially arranged in an engaged mode, and drainage belts are arranged on the side faces of the steel sheet pile and the steel pipe pile; the steel sheet pile comprises a web and a side plate, and a lock catch strip is arranged at the top of the side plate. The steel pipe pile comprises a main steel pipe and a side buckling strip, and the side buckling strip and the lock catch strip are matched in an engaged mode. A plurality of steel bars are further arranged on the side faces of the steel sheet piles and the side faces of the steel pipe piles, the steel bars are arranged in the length direction of the steel sheet piles and the length direction of the steel pipe piles, the drainage belts are arranged between the steel bars, drainage belt clamping heads are arranged at the lower ends of the steel sheet piles and the lower ends of the steel pipe piles, and the tops of the drainage belts are arranged in the clamping heads. The drainage belts are arranged outside the steel sheet piles and the steel pipe piles, so that pore water pressure can be effectively eliminated after piling, drainage treatment on the foundation pit before piling is omitted, and the construction period is shortened.
本发明涉及建筑施工领域，具体涉及一种用于软土地层的PC工法桩及其施工工艺，其中PC工法桩，包括：依次咬合设置的钢板桩和钢管桩，所述钢板桩和所述钢管桩侧面设置有排水带；所述钢板桩包括：腹板和侧板，侧板顶部设置有锁扣条；所述钢管桩包括：主钢管和侧扣条，所述侧扣条和所述锁扣条相互咬合匹配；所述钢板桩和所述钢管桩侧面还设置有若干钢条，所述钢条沿所述钢板桩和所述钢管桩长度方向设置，所述排水带设置在所述钢条之间，所述钢板桩和所述钢管桩下端设置有排水带卡头，所述排水带顶部设置在所述卡头内。本发明通过在钢板桩和钢管桩外设置排水带，使得打桩后能有效消除孔隙水压力，从而免去在打桩前对基坑排水处理，加快了工期。
