Abstract

The invention aims to provide a construction method for a sand barrier with a narrow sand-fixing net, which belongs to the technical field of sand control engineering. In the control of desertification, grid sand barriers, sandbag sand barriers, and grass grid sand barriers have been widely used to fix the mobile desert. The above sand barriers have many shortcomings, and it is difficult to achieve convenient construction, low cost and sand fixation effect. it is good. According to the excellent wind erosion resistance function of the narrow sand-fixing net, a construction line with an interval of 40cm to 120cm is drawn on the desert, and the center line of the flattened narrow sand-fixing net overlaps and is spaced parallel to the construction line. Spread a narrow sand-fixing net at 10cm to 12cm, take the sand-fixing net inserter, and insert the narrow sand-fixing net on the desert along the construction line, so that the narrow sand-fixing net is inserted along the construction line, and the construction is narrow Sand-fixing nets and sand barriers achieve the purpose of convenient construction, low cost and good sand-fixing effect.

Description

technical field

[0001] The invention relates to the technical field of sand control engineering, in particular to a construction method for sand barriers with narrow sand-fixing nets. Background technique

[0002] At present, in desertification control, grid sand barriers, sandbag sand barriers, and grass grid sand barriers have been widely used to fix the mobile desert, and then plant psammophytes on the fixed desert. Due to the high transportation cost and high construction cost of the straw grids, and the straw grids will lose their sand-fixing function due to weathering and corrosion in three years, so that the planted plants will face the situation of being eroded by wind and sand again; The cost per unit area of ​​grid and sandbag sand barriers is much higher than that of grass grid sand barriers, which is an economic burden that cannot be borne by large-scale sand control projects. The applicant previously provided a method for sand-fixing sand ridges with U-shaped s...

Examples

Embodiment Construction

[0021] Now the present invention will be further described according to the accompanying drawings:

[0022] As shown in the figure, a construction method of a narrow sand-fixing net sand barrier of the present invention is characterized in that the narrow sand-fixing net 1 is between 20cm and 36cm in width and between 10cm and 12cm in length, and has a porosity of between 20cm and 36cm. Between 10% and 25% plastic mesh.

[0023] Draw a construction line 2 on the desert according to the landform. The construction line 2 can be a straight line with an interval of 40cm to 120cm, or a curve, which can be continuous or section by section; flattened narrow strips The center line of the sand-fixing net 1 overlaps the construction line 2 in parallel, spread out a narrow sand-fixing net at an interval of 10cm to 12cm, take the sand-fixing net inserter, and insert the narrow sand-fixing net 1 on the desert in sequence along the construction line 2 , make the top edge of the narrow sand...
