Slope protection reinforcement device for water conservancy projects

Abstract

The present invention is a water conservancy utility slope protection device, comprising a fixed head, a screw, a compression spring, a gasket, a nut and at least two bolt bodies; the fixed head includes a connecting sleeve and a number of connecting heads corresponding to the bolt body, The connecting head is obliquely arranged on the connecting sleeve; the anchor body includes a front section extending into the anchor hole and a rear section away from the front section, one end of the connecting sleeve is hinged with the connecting head ball, the other end of the connecting sleeve is connected to the rear of the anchor body Sectional threaded connection; gasket and pressure spring are set on the screw from top to bottom in sequence, and the nut is located above the gasket. The anchor body in the slope protection device has higher stability in the sand and gravel layer, and also improves the pullout resistance of the anchor body; and by using the compression spring, it can not only protect the slope protection net, but also protect the anchor. The main body is protected, which reduces the maintenance cost and difficulty of the project, enables the slope protection net to continue to have slope protection ability after the overall slippage, and improves the durability of the slope protection project.

Description

technical field [0001] The invention relates to the technical field of construction equipment for water conservancy projects, in particular to a slope protection reinforcement device for water conservancy projects. Background technique [0002] Slope protection nets are often used in water conservancy projects to reinforce the surface of river embankments and dams to avoid soil erosion. The slope protection net in the prior art is a simple metal net, which is covered on the surface of the embankment to achieve the purpose of preventing soil erosion. The existing method of fixing the slope protection net on the embankment is relatively simple: one is to reinforce the slope protection net with anchor rods. The other is the bin grid. The slope protection net is directly laid on the embankment with a relatively flat slope, and the slope protection net is divided into small grids of one to two meters square, and pebbles and other stones are placed in the small grids. The weight...

Problems solved by technology

[0003] In the actual use of the project, the anchor rod is very easy to loosen in the sand layer, which will cause the overall slope protection net to slide, and the stones are also easy to loosen under the erosion of water flow, and at the same time, the loosened stones will also damage the slope protection net under the impact of water flow. Cause damage, lead to failure of slope protection net, and cause economic loss
