Series-connected type sand trapping net cage and sand storage dam constructed by same

Abstract

The invention aims to provide a series-connected type sand trapping net cage and a sand storage dam constructed by the same, belonging to the technical field of engineering. Each series-connected type sand trapping net cage with an A-shaped section consists of a front bracket, a rear bracket and sand trapping nets stretched on the front bracket and the rear bracket, the series-connected type sand trapping net cage is formed by connecting all series-connected type sand trapping net cages in series one by one along a desert, the quicksand of the desert is intercepted and trapped by the series-connected type sand trapping net cage and gradually rises, and when the height of the sandpile is 20-30 cm far from the top end of the series-connected type sand trapping net cage, the series-connected type sand trapping net cage is pulled up, the first construction structure is repeated at the top of the sandpile; when the quicksand is piled to the height 20-30 cm far from the top end of the series-connected type sand trapping net cage again, the series-connected type sand trapping net cage is lifted up according to the mode and the structure again; a check dam which takes the series-connected type sand trapping net cage as the top is formed by repeating the mode and structure for three times, four times and several times so as to achieve the purpose that the quicksand of the desert is intercepted so as not to invade inlands.

Description

technical field [0001] The invention relates to the technical field of engineering, in particular to a series-type sand-catching net cage and a sand-retaining dam constructed thereof. Background technique [0002] Driven by the wind, desert quicksand continuously intrudes into the grasslands, forests and cultivated land on the edge of the desert. In some parts of the Yellow River loop, high mobile sand dunes buried the forests by the river, and then flowed straight into the Yellow River channel, making the river water sandy. The drastic increase in the amount of water caused the river bed to rise, threatening the safety of both sides of the river. 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 ...

Problems solved by technology

Using construction sand barriers and other engineering measures to stop quicksand, although it can play a role in local sand fixation, but in the face of the vast desert mobile sand dunes, sand barriers and other measures seem powerless
