Embodiment Construction

[0016] As shown in the figure, a single series-connected sand-catching net is composed of a sand-catching net 1 and a support rod 2. The sand-catching net 1 is mechanically woven into a mesh density of nylon wire that meets the design requirements and can intercept 40%-60% of the construction destination. %Nylon wire mesh for desert quicksand, the width of the net is designed according to the height of the sand-catching net 1, the sand-catching net 1 is cut according to the designed length, the left and right ends of the sand-catching net 1 are rolled into a cylindrical shape and sewn into a support sleeve 4 .

[0017] The support rod 2 is a bamboo pole, a wooden pole, an iron pipe, and a plastic pipe that meet the design requirements one by one. Fixed to form a single serial sand catching net.

[0018] Along the top line of the crest of the mobile sand dune, according to the design route, the single serial sand-catching nets are connected one by one next to each other in ser...

Abstract

The invention aims to provide a serial sand catching net which is fast in construction, low in cost and can achieve mechanized production, and a sand-blocking dam built by the same, which belongs to the technical field of engineering. The serial sanding catching net in the invention is formed by a nylon yarn knitted sand catching net and a steadying bar, wherein the lower part of the steadying bar is inserted a dune to be used as a spud pile; on the wandering dune, the serial sand catching net is stretched and tensed; the lower part of the steadying bar is fixed on the dune; the serial sand catching net is erected one by one according to the designed line to be constructed into a sand catching net for the sand blocking dam; thus, flowing sand in deserts can be intercepted and captured by the sand catching net and is accumulated in inner and external sides of the sand catching net for the sand blocking dam to form the sand blocking dam.

Description

technical field [0001] The invention relates to the technical field of engineering, in particular to a serial sand-catching net and a sand-retaining dam constructed thereof. Background technique [0002] Driven by the wind, the desert quicksand continuously intrudes into the grasslands, woods and cultivated land on the edge of the desert. The amount of sand increased sharply, raising the river bed and threatening the safety of both banks. Desert quicksand has also climbed up the slopes of Yinshan and Helanshan, and has a tendency to climb over the mountains. Stop quicksand with construction sand barrier and some other engineering measures, though can play sand-fixing effect locally, but face the vast desert mobile sand dune, measures such as sand barrier just seem powerless. Therefore provide a kind of construction convenient and quick and cheap and efficient engineering measure to intercept desert quicksand, has been the needs of the times. Contents of the invention ...
