Slope reinforcement bolt for construction engineering

Abstract

The invention belongs to the technical field of slope reinforcement, and specifically relates to a slope reinforcement anchor rod for construction engineering, which includes a protective plate arranged on the slope surface; the protective plate is fixedly connected to the slope surface through the anchor rod; The anchor rod includes a first hollow tube, a second hollow tube, an outer fixing unit, an extension unit, an inner fixing unit and a counterweight unit; the outer fixing unit includes a first swing rod; the inner fixing unit includes a fixing ring, a second A slide plate, a first fixed rod, a second slide plate, a second fixed rod and a second air bag, and the internal fixed unit is evenly distributed on the inner wall of the third hollow tube; the counterweight unit includes a swing plate and a second swing rod; the The right end of the second swinging rod is provided with a diaphragm; the invention has a simple structure and can realize the complete fixation of the anchor rod, meanwhile, the service life of the protective plate is long, and the anchor rod can be reused to reduce waste of resources.

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...

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
