Deep foundation pit assembly type section steel front inclined strut support construction method
The invention provides a deep foundation pit fabricated profile steel front inclined strut support construction method, which belongs to the technical field of building construction, and comprises the following steps: firstly, measuring and determining the plane positions of an HC construction method pile and an inclined strut through a total station, checking the material quality and processing; then the HC steel piles and the Larsen steel sheet piles are driven into the ground through a special pile driving and pulling machine, and meanwhile the front inclined struts are inserted. The coping beams and the reinforcing piers are poured on the tops of the HC piles, and the overall stability is improved. And after the coping beam reaches the design strength, the foundation pit is excavated to the bottom in a segmented and layered mode. When the basement structure is constructed, the mode of disconnecting reinforcing bar welding or reserving holes is adopted at the position penetrating through the H-shaped steel, and water stop steel plates are arranged at the joints of the bottom plate and the H-shaped steel and the joints of the wall and the H-shaped steel. And finally, the external H-shaped steel is buried in backfill soil, the internal H-shaped steel is cut off, and the HC construction method pile is recycled through a cement paste synchronous grouting method. The supporting system optimizes the supporting and the basement structure and ensures the safety and stability of foundation pit excavation and basement structure construction.
本发明提供了一种深基坑装配式型钢前置斜撑支护施工方法，属于建筑施工技术领域，包括：首先通过全站仪测量确定HC工法桩和斜撑的平面位置,检查材料质量并进行加工。然后使用专用打拔桩机将HC钢桩和拉森钢板桩打入地下,同时插入前置斜撑。在HC桩顶部浇筑压顶梁和加强墩,增加整体稳定性。在压顶梁达到设计强度后,分段分层开挖基坑至底部。地下室结构施工时,在穿过H型钢处采取断开配筋焊接或预留孔洞的方式,并在底板和墙体与H型钢交接处设置止水钢板。最后,将外部H型钢埋置于回填土中,内部H型钢割除,并采用水泥浆同步注浆法回收HC工法桩。该支护体系优化支护与地下室结构确保了基坑开挖和地下室结构施工的安全稳定。
