Anchor cable stress automatic monitoring device for foundation pit support

HAO JUN / QIN WENXUAN / LI JIE / AN NING

The invention discloses an anchor cable stress automatic monitoring device for foundation pit supporting, and belongs to the field of foundation pit monitoring. An anchor cable is inserted into the foundation pit slope, a supporting body is fixedly mounted on the side wall of the foundation pit slope, a through hole is formed in the side wall of the supporting body, the anchor cable penetrates through the through hole, a mounting plate is detachably mounted on the side wall of the supporting body, and a supporting plate is hinged to the side wall of the mounting plate. A first communication port and a second communication port are formed in the side wall of the mounting plate and the side wall of the supporting plate correspondingly. Through mutual cooperation of a supporting plate, a supporting rod, a sliding block and a first threaded rod, in the process of rotating the first rotating rod, the first rotating rod drives the sliding block to move along a first sliding groove, then in the moving process of the sliding block, the supporting plate is driven by the supporting rod to rotate around a hinge point, and the supporting plate is gradually perpendicular to an anchor cable in the rotating process; the supporting plate does not need to be manufactured again according to the angle between the foundation pit slope and the anchor cable, and the convenience of the device is improved.

本发明公开了基坑支护的锚索应力自动化监测装置，属于基坑监测领域，包括，基坑边坡与基座；基坑边坡内插设有锚索，基坑边坡的侧壁上固定安装有支护体，支护体的侧壁上开设有通孔，且锚索穿过通孔，支护体的侧壁上可拆卸安装有安装板，安装板的侧壁上铰接有支撑板，安装板与支撑板的侧壁上分别开设有第一连通口与第二连通口。通过支撑板、支撑杆、滑块、第一螺纹杆的相互配合，在转动第一转杆的过程中，第一转杆带动滑块沿着第一滑槽移动，然后滑块移动的过程中通过支撑杆带动支撑板围绕铰接点转动，支撑板在转动的过程中逐渐与锚索垂直，无需根据基坑边坡与锚索之间的角度重新制作支撑板，提高了装置的便捷性。
