Supporting structure for soil nail slope protection in deep foundation pit construction
The invention relates to a supporting structure for soil nail slope protection in deep foundation pit construction, and relates to the field of deep foundation pit supporting, the supporting structure comprises a foundation pit body, a tensile anchor cable and a concrete wall poured on the side wall of the foundation pit body, one end of the tensile anchor cable is anchored on the side wall of the foundation pit body, and the other end of the tensile anchor cable is embedded in the concrete wall; the tensile anchor cable comprises an anchor rod sleeve, a locking rod and a plurality of limiting pieces, the locking rod is coaxially and rotatably connected into the anchor rod sleeve, the limiting pieces comprise a plurality of tensile rods, a sliding hole communicating with the containing hole is formed in the anchor rod sleeve in a penetrating mode, the tensile rods are slidably connected into the sliding hole, and the ends of the tensile rods are connected with the locking rod; the sliding direction of the tensile rods is perpendicular to the axial direction of the anchor rod sleeve, and the locking rod is used for driving the multiple tensile rods to slide synchronously. According to the tensile anchor cable, the pulling resistance between the tensile anchor cable and a soil body can be fully improved, the slope protection construction process is simplified, construction can be continued without waiting for cement paste hardening, and therefore the construction period of a slope protection structure is greatly shortened.
本申请涉及一种用于深基坑施工中土钉护坡的支护结构，涉及深基坑支护的领域，其包括基坑本体、抗拉锚索和浇筑于基坑本体侧壁上的混凝土墙，抗拉锚索一端锚固于基坑本体侧壁上、另一端埋设于混凝土墙内；抗拉锚索包括锚杆套、锁定杆和限位件，锁定杆同轴转动连接于锚杆套内，限位件设有多个，限位件包括多个抗拉杆，锚杆套上贯穿开设有与容纳孔连通的滑孔，抗拉杆滑动连接于滑孔内且端部与锁定杆连接，抗拉杆的滑动方向与锚杆套的轴向垂直，锁定杆用于驱动多个抗拉杆同步滑动。本申请的抗拉锚索能够充分提高抗拉锚索与土体之间的抗拔力，并且简化了护坡的施工工艺，无需等待水泥浆硬化即可继续施工，从而大大缩短了护坡结构的施工工期。
