Abstract

The invention discloses a completely recyclable end support ground anchor, which comprises an anchor rod, an anchor rod sleeve and anchor flukes. The anchor rod is a straight rod with the lower end provided with disc-shaped flanges; the tubular anchor rod sleeve is sheathed on the lower part of the anchor rod; circular flanges are arranged on the bottom surface of the anchor rod sleeve; and upper ends of a plurality of anchor flukes are hinged on the outer edges at the lower ends of the circular flanges arranged on the bottom surface of the anchor rod sleeve. According to the invention, the end support ground anchor can be put into use immediately after being assembled and has a plurality of anchor flukes and large anchoring force, the assembly and the disassembly is fast and convenient, and the complete recycling of the ground anchor is not influenced even if collapse happens to the bottom of an anchor hole.

Description

technical field

[0001] The present invention mainly relates to the field of rock-soil anchorage in construction engineering, and in particular to a temporary and fully recyclable end-bearing ground anchor. Anti-force anchoring system for static load tests on foundations, etc. Background technique

[0002] At present, the bolt technology used in engineering is mostly fixed and non-removable bolts, and there are also a few removable bolts. There are some bolts that are anchored into the soil, but this type of bolt has few claws and small anchoring force, and because the claws are anchored into the soil, it is difficult to remove them. It can be known from the mechanical properties of rock and soil that the end bearing capacity of various rock and soil is much greater than the friction provided by it. Just because the side friction force provided by the geotechnical system is small, if a larger anchoring force is required, only by increasing the diameter, length and quant...
