Embodiment 1

[0034] like figure 1 A sandy construction waste gravel sand fixation structure shown includes a grid-shaped sand barrier 1. The grid-shaped sand barrier 1 is made of crushed construction waste into 10-50mm crushed stones, and its side length is 1.5 mm. m, each side is a triangular ridge shape with a bottom width of 34cm and a height of 17cm.

[0035] Wherein, the side length of the sand barrier can range from 1-2m, and the size range of the triangular ridge is 30-40cm in bottom width and 15-20cm in height.

[0036] The production of the construction waste gravel sand-fixing structure is to crush a large amount of sandy construction waste formed by the demolition of nearby towns into 10-50mm crushed gravel with an energy-saving jaw crusher, and make the crushed gravel with a bottom width of 30-40cm and a height of 30-40cm. 15-20cm triangular ridge shape, 1-2m square grid-shaped sand barrier.

Embodiment 2

[0038] like figure 2 A kind of sandy construction waste gravel sand-fixing structure shown, comprises belt-shaped sand barrier 2, and this belt-shaped sand barrier 2 is made of crushed gravels of 10-50 mm by construction waste, with a bottom width of 40 cm and a height of 20 cm. Triangular ridge shape. Among them, the direction of the ridge is consistent with the local main wind direction (such as figure 2 The middle arrow points to) vertically, that is to say, the main wind will be blocked by the belt-shaped sand barrier 2 and weakened. There are several ridges parallel to each other with a distance of 2m.

[0039] The production of the construction waste gravel sand-fixing structure is to crush a large amount of sandy construction waste formed by the demolition of nearby towns into 10-50mm gravel with an energy-saving jaw crusher. Triangular ridge shape.

Embodiment 3

[0041] like image 3 A gravel sand-fixing structure of sandy and gravel construction waste is shown, including a uniformly flat sand barrier 3, which is composed of crushed construction waste into 10-50mm crushed stones, which are evenly spread On the dunes, where the coverage is between 40-60%.

[0042] The sand-stone construction waste gravel sand-fixing structure is made by crushing a large amount of sand-stone construction waste formed by the demolition of nearby cities and towns into 10-50mm crushed gravel with an energy-saving jaw crusher, and spreading them evenly on the sand dunes.

Abstract

The invention discloses a sand-fixing construction waste gravel structure, comprising a sand barrier, the sand barrier is in the shape of a square, a belt or evenly tiled, and is composed of crushed construction waste gravels with a particle size of 10-50mm; and Production Method. The present invention has the same sand-fixing effect as the natural gravel sand barrier, and can achieve once-and-for-all sand-fixing effects after implementation. It can realize no pollution, no rainfall runoff, no water consumption, no influence on the growth of natural plants, and can continue to effectively play windproof Sand-fixing efficiency.

Description

technical field [0001] The invention relates to the technical field of desertification prevention and control, in particular to a desert control method in an arid area, in particular to a sand-stone construction waste gravel sand-fixing structure and a manufacturing method thereof. Background technique [0002] my country currently has a desert and sandy land area of ​​1,731,100 km 2 , accounting for 18.03% of my country's total land area. The national economic loss due to land desertification including desertification is about 470 billion yuan. Under the existing technical, economic and natural environmental conditions, the sandy land that can be controlled in recent decades is about 500,000 km 2 . According to the "National Ecological Environment Construction Plan" promulgated by the State Council in 1998, in terms of desertification control, the short-term goal (2010) is proposed to be 220,000 km 2 , the mid-term target (2030) is 400,000 km 2 . [0003] The regions ...
