Problems solved by technology

The high vertical straw sand barrier with this structure and setting mode is only suitable for the windy sand environment area with general strength, while in the strong wind area, the grid row will be broken or broken due to the straw breaking, or the grid row and the column will be damaged due to the strong wind erosion at the bottom. hang or even fall
It can be seen that the high vertical reed sand barrier with conventional structure is not suitable for strong wind areas, and it is necessary to develop a construction method for high vertical straw sand barriers suitable for strong wind areas

Embodiment 1

[0020] A method for constructing a high vertical straw sand barrier suitable for strong wind areas according to the present invention, the sand barrier involved in the method is composed of fixed piles, anchor piles, anchor cables, straw, reinforcing ribs, cross bars and fixed wires. Composition, longitudinally equidistant or unequal-distance fixed reinforcing ribs 2 on the fixed pile 1, the distance between the fixed piles 1 is 2-4m; at the intersection of the reinforced ribs 2 on the side of the fixed pile 1, fix the reinforced ribs 2 with U-shaped nails 3; On the windward side of the rib 2, the cut straw 6 is leaned against the reinforcing rib 2, the straw 6 is clamped along the reinforcing rib 2 with the cross bar 7, and the reinforcing rib 2, the straw 6 and the cross bar 7 are bound and fixed with the fixing wire 8, The distance between the fixed wire 8 nodes is 10-30cm; the anchor pile 4 is fixed on the ground at 1.5m on the windward side and the leeward side of the fixe...

Embodiment 2

[0026] A kind of construction method of the high vertical straw sand barrier suitable for strong wind area according to the present invention, the sand barrier involved in this method is according to embodiment 1, concrete operation is carried out according to the following steps:

[0027] a. Measure and set out according to the design, draw the position line of the sand barrier on the ground, nail the fixed pile 1 into the soil with a hammer, keep the distance between the fixed piles 1 at 3m; wind the reinforcing rib 2 at the longitudinal unequal distance on the fixed pile Tighten and tighten in one circle, and fix the reinforcement rib 2 at the intersection of the reinforcement rib 2 on the side of the fixed pile 1; the U-shaped nail 3 is a U-shaped iron nail with a diameter of 3mm and a length of 30mm; use the same method, sequentially Connect and fix with other fixed piles 1;

[0028] b. Vertical to the laying direction of the sand barrier, use a hammer to vertically drive...

Embodiment 3

[0032] A kind of construction method of the high vertical straw sand barrier suitable for strong wind area according to the present invention, the sand barrier involved in this method is according to embodiment 1, concrete operation is carried out according to the following steps:

[0033] a. Measure and set out according to the design, draw the position line of the sand barrier on the ground, nail the fixed pile 1 into the soil with a hammer, keep the distance between the fixed piles 1 at 4m; wind the reinforcing rib 2 at the longitudinal equidistant position on the fixed pile Tighten the circle, tighten it, fix it with U-shaped nail 3 at the intersection of reinforcement rib 2 on the side of fixed pile 1, and use the same method to connect and fix it with other fixed piles 1 in sequence;

[0034] b. Vertical to the laying direction of the sand barrier, use a hammer to vertically drive the anchor pile 4 into the ground at 3m from the windward side and the leeward side of the f...

Abstract

The invention relates to a construction method of a high-standing type straw sand barrier suitable for a strong wind area. The sand barrier involved in the method comprises a fixing pile, an anchoring pile, an anchoring pull rope, straw, reinforcing ribs, cross bars and fixing wires. The method aims to solve the problem that a conventional high-standing reed sand barrier is severely damaged when applied to the strong wind area, through increase of the number of transversely arranged reinforcing ribs and increase of density of binding points, distances between fulcrums on plant straw are narrowed by increasing transverse and vertical strength of a grille row, so that the bending degree of the plant straw is reduced, the overall strength of the sand barrier is finally improved, and the sand barrier can resist long-term blowing of strong wind; through increase of the width of sand stabilization grids on the windward side and the leeward side of the sand barrier and reduction of the specification of the grids, the earth's surface stability and wind erosion resistance are enhanced, and wind-drift sand undercutting can be resisted. With the adoption of the method, the wind resistance of the high-standing straw sand barrier is enhanced, the service life is prolonged, the sand prevention benefit is increased, and the method has significant application value for construction of a strong wind area mechanical sand prevention system.

Description

technical field [0001] The invention relates to sand prevention and control technology, in particular to a construction method of a high vertical straw sand barrier suitable for strong wind areas. Background technique [0002] Sandstorm disasters pose an important threat to human production and life in sandy areas, and the prevention and control of sandstorm disasters is an important guarantee for economic and social development in sandy areas. In the practice of sand prevention and control, people have developed various forms of sand prevention measures. According to the principle of action, sand control measures can be divided into four types: "fixation, resistance, transmission, and guidance". In practical applications, sand control systems are often combined. Sand blocking measures are generally located at the front of wind and sand, and are an important part of the sand control system, and have an important role in wind and sand blocking. [0003] High vertical sand b...
