Embodiment 1

[0023] a, the production of sand barriers: bundle the plant stalks into grass handles 1 with a diameter of 1cm, and then cut the grass handles 1 into 1m sections;

[0024] b. Draw a line on the ground of the sand barrier area to be laid to determine the position of the sand barrier, and embed one end of the fixed pile 2 in the surface layer 3 on the drawn line, with an embedding depth of 30cm, and the distance between the fixed piles 2 is 1m;

[0025] c. Place the grass bar 1 made in step a parallel to the surface between the two fixed piles, and fix the grass bar 1 on the fixed piles 2 one by one in parallel to form a sand barrier. The lower layer of the sand barrier is a tight strip 5 , the spacing is 5mm, the middle layer of the sand barrier is a dredging strip 6, the spacing is 8mm, the upper layer of the sand barrier is a ventilation strip 7, the spacing is 15mm, and the same width can be used.

Embodiment 2

[0027] a, the production of sand barriers: bundle the plant stalks into grass handles 1 with a diameter of 2cm, and then cut the grass handles 1 into 2m sections;

[0028] b. Draw a line on the surface of the sand barrier area to be arranged to determine the position of the sand barrier, and embed one end of the fixed pile 2 in the surface layer 3 on the drawn line, with an embedding depth of 35cm, and the distance between the fixed piles 2 is 1.2m;

[0029] c. Place the grass bar 1 made in step a parallel to the surface between the two fixed piles, and fix the grass bar 1 on the fixed piles 2 one by one in parallel to form a sand barrier. The lower layer of the sand barrier is a tight strip 5 , the spacing is 7mm, the middle layer of the sand barrier is a dredging strip 6 with a spacing of 12mm, the upper layer of the sand barrier is a ventilation strip 7 with a spacing of 18mm, and different widths can be used.

Embodiment 3

[0031] a, the production of sand barriers: bundle the plant stalks into grass handles 1 with a diameter of 3cm, and then cut the grass handles 1 into 1.5m sections;

[0032] b. Draw a line on the surface of the sand barrier area to be laid to determine the position of the sand barrier, and embed one end of the fixed pile 2 in the surface layer 3 on the drawn line to a depth of 40cm, and the distance between the fixed piles 2 is 1.5m;

[0033] c. Place the grass handle 1 made in step a parallel to the surface between the two fixed piles, and then fix the grass handle 1 on the fixed pile 2 one by one in parallel to form a sand barrier. The lower layer of the sand barrier is a tight strip 5. The spacing is 8mm. The middle layer of the sand barrier is a dredging strip 6 with a spacing of 15mm. The upper layer of the sand barrier is a ventilation strip 7 with a spacing of 20mm. The same width can be used.

Abstract

The invention relates to a tying and placing method for a vertical sand barrier, which adopts a nonuniform structure, namely, the porosity or ventilation coefficients at the upper part and the lower part are different; the sand barrier is layered in the vertical direction; and the lower structure is compact, the middle structure is sparse, and the upper structure is ventilative. The high vertical structure tied and placed through adopting the method adapts to the vertical distribution of concentration of wind-drift sand, thereby not only effectively withholding the sand delivery of wind-drift sand, but also reducing the wind pressure on the sand barrier, reducing the breakage damage of wind power, meanwhile reducing the material consumption and sand-prevention cost; and the method provided by the invention can be applied in the mechanical sand-prevention engineering at all areas with sand storms.

Description

technical field [0001] The invention relates to a construction method of a sand prevention project, in particular to a method for erecting a vertical sand barrier. Background technique [0002] Wind and sand disasters not only affect arid and semi-arid regions, but also affect other regions, and have become a global disaster. An important technical means for the prevention and control of wind and sand disasters is to set up engineering sand control measures to achieve the purpose of wind and sand control through the functions of "consolidation, resistance, transportation, and guidance". Sand control measures are an important engineering sand control measure and an important part of the sand control system. The shortage of sand control materials, high cost and high labor cost are the main problems faced by the current mechanical sand control projects, which limit the large-scale implementation of sand control projects. How to effectively reduce the material cost of mechanic...
