Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, a large gap is formed when the hook head is inserted, causing the fixing device to be unable to be fixed, and the stress area of ​​the hook head is too large during the insertion process, which makes it difficult to insert the fixing device and the gap after the fixing device is incorporated is Filling, the problem that the fixing device cannot be fixed after the concrete is dried, a kind of slope reinforcement anchor rod for construction engineering proposed by the present invention

Abstract

The invention belongs to the technical field of side slope reinforcement, and particularly relates to a side slope reinforcement anchor rod for construction engineering. The side slope reinforcement anchor rod includes a protective plate arranged on the slope surface, and the protective plate is fixedly connected to the slope surface through an anchor rod; the anchor rod comprises a first hollow pipe, a second hollow pipe, an external fixing unit, an extension unit, internal fixing units and a counterweight unit; the external fixing element comprises a first swinging rod; each internal fixingunit comprises a fixing ring, a first sliding plate, a first fixing rod, a second sliding plate, a second fixing rod and a second air bag, and the internal fixing units are evenly distributed on the inner wall of the third hollow tube; and the counterweight unit comprises a swinging plate and a second swinging rod, and a diaphragm is arranged at the right end of the second swinging rod. Accordingto the side slope reinforcement anchor rod for construction engineering, the structure is simple, the anchor bolt can be fixed completely, meanwhile, the service life of the protective plate is long,and the anchor bolt can be reused, so that waste of resources is reduced.

Description

technical field [0001] The invention belongs to the technical field of slope reinforcement, in particular to a slope reinforcement bolt for construction engineering. Background technique [0002] Slope landslides, sideslips, collapses and other factors are the main disastrous factors for slope damage. At present, anchoring technology is widely used in domestic construction of roads, railways, foundation pits, open-pit mines and other engineering practices to strengthen rock and soil slopes. There are usually two ways to strengthen the slope, one is superficial reinforcement, and the other is deep reinforcement. Among them, the main methods of surface fixation are hanging protective nets, shotcrete, anchor rods, frame beams, etc., and deep reinforcement The main method is the anchor cable. For slope reinforcement projects that require a high level of slope safety, it is necessary to solve the superficial stability and deep stability of the slope at the same time or alternatel...
