Embodiment Construction

[0010] The present invention will now be further described with reference to the accompanying drawings: the sand blocking net described in the present invention is a plastic net with a width between 15cm and 50cm and a porosity between 45% and 55%.

[0011] like figure 1 As shown in the above, the construction method of the hanging bag-shaped high vertical sand-blocking net is characterized in that: in the direction perpendicular to the main wind direction on the desert, a loader is used to build a sand dam with a height between 90cm and 250cm. , the top of the sand bar is flattened into a platform with a width between 80cm and 200cm, and a ditch is dug on the platform. The width of the ditch is between 30cm and 70cm, and the depth is between 15cm and 50cm; The sand-blocking net with a width between 100cm and 350cm, spread the sand-blocking net along the ditch on the sand dam platform. Press the sand-blocking net into the bottom of the ditch, and insert the wooden strip into ...

Abstract

The invention aims to provide a construction method of a hanging bag-shaped high-vertical sand-retaining net and sand-retaining dam, which belongs to the technical field of sand control engineering; The construction structure is changed from a single suspension like a curtain to a hanging bag-shaped high vertical sand-blocking net in the shape of a mesh bag with desert sand suspended at the bottom of the bag, so that the sand-blocking net has a front mesh surface and a rear mesh surface, which can be used Intercept the desert quicksand between the two mesh surfaces of the hanging bag-shaped high vertical sand-blocking net and the front and rear sides of the sand-blocking net; the bottom of the net is suppressed by sand piles, and the sand-blocking net will not be blown from the bottom of the net by strong winds The erosion blows down, and the hanging bag-shaped high vertical sand-blocking net is constructed on the top of the artificially piled sand dam to form the hanging-bag-shaped high vertical sand-blocking net sand-blocking dam.

Description

technical field [0001] The invention relates to the technical field of sand control engineering, in particular to a construction method of a hanging bag-shaped high vertical sand barring net sand barring dam. Background technique [0002] At present, in desertification control, plastic nets have been widely used to construct high-vertical sand-blocking nets to intercept and fix mobile deserts. The surface is easily blown, and the blocked wind changes from the horizontal direction to the up and down vertical direction. The vertical downward wind will erode the sand at the bottom of the sand-blocking net, so that the bottom of the sand-blocking net will be emptied and invalid, and then fall down. The sand-blocking net cannot be used to build a sand-blocking dam, so the invention of a hanging bag-shaped high-vertical sand-blocking net to block the sand-blocking dam is already a need for desert governance. [0003] The applicant published "Fixing and Utilization of Mobile Sand ...
