Problems solved by technology

[0006] The construction method of embedded sand-blocking net sand ridges to fix mobile dunes is a construction method explored by the applicant from the engineering practice of constructing eight-shaped cage sand barriers to fix mobile sand dunes. The eight-shaped mesh cage sand barrier is the same, but the material cost is greatly reduced, and the construction speed is greatly improved compared with the eight-shaped mesh cage sand barrier

Embodiment Construction

[0013] Now in conjunction with the accompanying drawings the present invention will be further described: as figure 1 , 2 As shown, the embedded sand blocking net 1 of the present invention is a plastic net with a width between 30cm and 50cm and a porosity between 35% and 55%.

[0014] Such as image 3 As shown, the construction method of the embedded sand-blocking net sand ridge to fix the mobile sand dune is: move the sand ridge line of the mobile sand dune 4 from the side of the leeward slope to the direction of the windward slope by 1m to 10m, and pile up a height of 35cm to 60cm. For sand ridges with a windward slope angle of less than 32°, place the bottom edge of the sand-blocking net with a width between 30cm and 50cm downward, and use mechanical devices to insert the sand-blocking net vertically from the top of the sand ridge into the interior of the sand ridge. The top edge of the sand net 1 exposes the top of the sand ridge by 1cm to 5cm, forming a buried sand-blo...

Abstract

The invention aims at providing a moving dune fixing construction method through a buried sand blocking net barrier beach and belongs to the technical field of desertification control engineering. By the aid of the method, a moving dune is fixed under the buried sand blocking net barrier beach. The construction method comprises pushing the sand ridge of the moving dune from one side of the leeward slope for 1m to 10m towards the windward slope, and piling up the burrier beach, the height of which is 35cm to 60cm and the windward slope angle of which is 32 degrees; putting the bottom of the sand blocking net which is 30cm to 50cm wide downwards, and inserting the sand blocking net flatly and vertically from the top of the barrier beach into the barrier beach through a mechanical appliance to form the buried sand blocking net barrier beach at the top of the moving dune.

Description

technical field [0001] The invention relates to the technical field of sand control engineering, in particular to a construction method for fixing mobile sand dunes to ridges with embedded sand retaining nets. Background technique [0002] At present, in the control of desertification, plastic mesh construction grids and high vertical sand-blocking nets have been widely used to intercept and fix the mobile desert. The above-mentioned construction methods must be equipped with matching brackets to support the sand-blocking net. Therefore Not only the cost of materials is high, but also the cost of transportation and construction is high, especially the high vertical sand blocking net, not only has high requirements on the support, but also is easy to be blown down by strong wind and become invalid. The construction method of the embedded sand-retaining net ridge and fixed mobile sand dunes, which is convenient and has a significant effect of retaining and fixing sand, is alre...
