Slope protection reinforcement device for water conservancy project

Abstract

The invention relates to a slope protection reinforcement device for a water conservancy project. The slope protection reinforcement device comprises a fixing head, a screw, a compression spring, a gasket, a nut and at least two anchor rod bodies; the fixing head comprises a connecting sleeve and connectors corresponding to the anchor rod bodies in number, and the connectors are obliquely arrangedon the connecting sleeve; each anchor rod body includes a front section extending into an anchor hole and a rear section away from the front section, one end of the connecting sleeve is in sphericaljoint with the connectors, and the other end of the connecting sleeve is in threaded connection with the rear sections of the anchor rod bodies; and the gasket and the compression spring are sequentially arranged on the screw in a sleeving manner from top to bottom, and the nut is located above the gasket. The anchor rod bodies in the slope protection device have higher stability in a sand layer,and the pulling resistance of the anchor rod bodies is improved; the compression spring is adopted, a slope protection net can be protected, the anchor rod bodies can be protected, the engineering maintenance cost and maintenance difficulty are reduced, the slope protection net continuously has the slope protection ability after overall slippage, and the durability of a slope protection project isimproved.

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
