Rapidly assembled recyclable frame anchor structure and construction method

Abstract

The invention relates to a rapidly-assembled recoverable frame anchor rod structure and a construction method, and belongs to the technical field of rock-soil anchorage. The structure comprises a frame, anchor rods and anchorage devices. The frame is composed of adhesive plaster bags, glass steel cylinders and cross connecting frames. The adhesive plaster bags are embedded in the glass steel cylinders and filled with gas, and the glass steel cylinders are inserted in four clamp grooves of the cross connecting frame respectively and connected through bolts to form the frame. The anchor rods are composed of free segments and anchoring segments. Glass steel pipes with external threads at the two ends serve as the free segments. The anchoring segments are composed of glass steel pipes connected with sleeves. The sleeves are provided with shape memory alloy pieces and wires, the shape memory alloy pieces are connected with control switches and power sources through conductors, and the control switches and the power sources are arranged outside a slope. The anchor rods penetrate a center hole of the cross connecting frame, and are anchored on the frame through the anchorage devices and base plates, and the shape memory alloy pieces are anchored in stable soil.

Description

technical field [0001] The invention relates to the technical field of rock-soil anchorage, and is suitable for soil slope and foundation pit engineering. Background technique [0002] With the rapid development of economic construction and the continuous increase of various infrastructure construction, a large number of slopes have emerged along the traffic roads, and there are many foundation pits in urban housing construction. In recent years, natural disasters such as rainstorms, floods, and earthquakes have occurred frequently, and the induced slope instability can be seen everywhere, often causing traffic blockages and river blockages, which bring great difficulties to emergency rescue and disaster relief, such as personnel and machinery being blocked and unable to move quickly. Rushing to the scene of the disaster affects the progress of disaster relief, causing a lot of life threats and property losses. Therefore, emergency rescue and disaster relief need to first c...
