Steel sheet pile and grouting anchor rod combined supporting structure and construction method thereof
The invention discloses a steel sheet pile and grouting anchor rod combined supporting structure and a construction method thereof.The steel sheet pile and grouting anchor rod combined supporting structure comprises a forward steel sheet pile, a reverse steel sheet pile, an anchor rod device and a slurry sealing fixing device.According to the steel sheet pile and grouting anchor rod combined supporting structure and the construction method thereof, the anchor rod device and the slurry sealing fixing device are connected in a combined mode, and grouting liquid is pressed into soil around anchor rods through slurry overflow holes of the grouting anchor rods; the grouting anchor rods and the soil body on the outer side of the foundation pit form a meshed whole, the grouting anchor rods and the steel sheet piles form a stable connecting system through the slurry sealing and fixing devices, the soil body, the grouting anchor rods and the steel sheet piles form a powerful foundation pit supporting structure through the construction, and the steel sheet piles do not need to be supported by combining profile steel enclosing purlins and profile steel inner supports. And meanwhile, construction of the steel sheet piles and the grouting anchor rods only needs local excavation of the working face, large-area excavation is not needed, and the foundation pit supporting construction efficiency is improved.
本发明公开了一种钢板桩与注浆锚杆组合支护结构及其施工方法，包括正向钢板桩、反向钢板桩、锚杆装置和封浆固定装置，本发明通过锚杆装置和封浆固定装置组合连接，将注浆液通过注浆锚杆的溢浆孔压入锚杆四周的土体中，使注浆锚杆和基坑外侧土体形成咬合的整体，注浆锚杆与钢板桩通过封浆固定装置形成稳固的连接体系，通过上述施工将土体、注浆锚杆和钢板桩形成强有力的基坑支护结构，无需型钢围檩和型钢内撑组合支撑钢板桩。同时钢板桩和注浆锚杆施工只需局部开挖工作面，无需大面积开挖，提高了基坑支护施工效率。
