Deep foundation pit wall supporting and reinforcing system and construction method
The invention discloses a deep foundation pit wall supporting and reinforcing system and a construction method.The system comprises an anchoring unit and a steel plate net, the anchoring unit comprises a combined anchor rod, an adjusting rod and a sleeve, the combined anchor rod comprises a head part, a middle part and a tail part, the center of each head part is provided with a through grouting hole, the front end of each head part is in a drill bit shape, and the rear end of each head part is provided with a threaded column; a threaded hole is formed in the front end of the middle part, anti-pulling protrusions are distributed in the middle of the middle part, a threaded column is arranged at the rear end of the middle part, a threaded hole is formed in the front end of the tail part, grouting branch holes are distributed in the middle of the tail part, a threaded column is arranged at the rear end of the tail part, and the grouting branch holes extend to the grouting hole from the side face of the tail part. The sleeve sleeves the rear end of the adjusting rod in a matched mode and is locked with the adjusting rod through a transversely-inserted bolt, and the steel screen is hung on a connecting piece on the rear end face of the sleeve. According to the deep foundation pit supporting structure, soil solidification, steel plate net hanging and concrete spraying are combined, the stability of the deep foundation pit supporting structure is enhanced, and construction is easy.
本发明公开了一种深基坑坑壁支护加固系统及施工方法，该系统包括锚固单元、钢板网，锚固单元包括组合锚杆、调节杆和套筒，组合锚杆包括中心均带有贯通的灌浆孔的头部件、中间件和尾部件，头部件的前端呈钻头状、后端设有螺纹柱，中间件的前端设有螺纹孔、中部分布有抗拔突起、后端设有螺纹柱，尾部件的前端设有螺纹孔、中部分布有灌浆支孔、后端设有螺纹柱，灌浆支孔从尾部件的侧面延伸至灌浆孔，调节杆的前端通过螺纹孔与尾部件的螺纹柱配合，套筒配合套在调节杆后端且二者之间通过横插的螺栓锁定，钢板网挂在套筒后端面的连接件上。本发明将固化土体、挂钢板网、喷射混凝土相结合，不仅加强了深基坑支护结构的稳定性，而且施工简单。
