Deep foundation pit slope supporting anchor rod, supporting structure and construction method
The invention relates to a deep foundation pit slope supporting anchor rod, a supporting structure and a construction method. The supporting anchor rod structurally comprises an inner core and a sleeve, and a tray and a lockset are arranged at the tail of the inner core. The sleeve is formed by connecting multiple barrels, and expansion rods are connected between the adjacent barrels. Each expansion rod comprises two hinged rod bodies, the sections of the rod bodies are semicircular, one end of each rod body is an open end, and the other end of each rod body is a closed end. The closed ends ofevery two rod bodies are hinged to each other, the open ends of the rod bodies are hinged to the barrels, and after every two rod bodies are closed, a tubular body can be formed. The barrels are provided with semicircular gaps along the positions hinged to the rod bodies, a guide frame is arranged outside the inner core, and the sleeve slidably sleeves the guide frame. According to the deep foundation pit slope supporting anchor rod, the supporting structure and the construction method, the reliability of deep foundation pit slope supporting can be effectively improved, and when the deep foundation pit slope supporting anchor rod is used for a loose soil layer, slope collapse can be effectively avoided.
本发明涉及一种深基坑边坡支护锚杆、支护结构及施工方法，支护锚杆的结构包括内芯和套筒，内芯的尾部设有托盘和锁具；所述套筒由多段筒体连接成，相邻筒体之间连接有扩张杆，所述扩张杆包括两段相互铰接的杆体，杆体的截面为半圆形，杆体的一端为开口端，另一端为封口端；两段杆体的封口端相互铰接，杆体的开口端与筒体铰接，两段杆体合拢后可围合构成管状体；所述筒体沿铰接杆体的位置设有半圆形缺口，内芯外部设有导向架，套筒滑动套设于导向架外部。本发明可以有效提供深基坑边坡支护的可靠性，在用于松散土层时，可有效防止边坡塌陷。
