What do you want to know about snow netting?

Snow net facilities are one of the more popular measures to effectively prevent and control wind-blown snow damage on highways. Snow protection nets can be widely used in sections of highways damaged by wind and snow. It can be used to build defenses based on hazards, change passive snow removal to active prevention, reduce wind and snow damage on roads, ensure smooth and safe highway traffic, reduce the cost of solving snow damage, improve highway service levels in snow-damaged areas, extend the service life of highways, and enhance and improve the operating environment. It has played an effective role in fundamentally controlling snow damage on roads.

The snow-proof net uses polyethylene polymer, which is cheap and easy to obtain, as the base material, and is prepared by modifying PE with ultraviolet absorbers, light stabilizers and antioxidants. By measuring tensile strength, elongation at break and -40℃ low-temperature folding test and other items have been tested. It has excellent mechanical properties, UV aging resistance and thermal oxygen aging performance, meeting the requirements for the use of snow nets. In addition, this product also has the advantages of low price, convenient processing and molding, simple installation, and beautification of road landscape. The porosity of the snow net is 40% to 55%.

Features of snow net:

1. Excellent resistance to UV aging and thermal oxygen aging;

2. Good low temperature crack resistance;

3. Long-term mechanical properties are stable;

4. The product color is green, which reflects the concept of green environmental protection, highlights the visual effect, and beautifies the road landscape;

5. Low price, easy to install, reusable and easy to disassemble.

The installation method of snow netting includes the following steps:

Step 1. Dig foundation pits: Excavate foundation pits at the construction site. The distance between two adjacent foundation pits is 3.0 to 8.0m, the pit depth is 0.4 to 0.8m, and each foundation pit is distributed in a straight line;

Step 2. Install the columns: bury the columns in the foundation pit, pour the concrete foundation, and ensure that the columns are exposed 1.3 to 4.3m, and ensure that each column is on the same straight line. The columns include end columns and a center column between the end columns. ;

Step 3. Install the snow-proof net: The snow-proof net is fixed on the windward side of the column. It can be fixed with pressure plates and expansion bolts. Considering the thermal expansion and contraction properties of the snow-proof net, it should not be too tight during installation, and a certain amount of slack should be reserved. , to prevent the snow net from shrinkage and damage;

Step 4. Install tension wires: In order to ensure the stability of the mesh structure, set up no less than 3 tension wires. First, tie a section of the upper, middle and lower tension wires to the end post at one end and fix them. Then pass the tension wire through the mesh of the snow net repeatedly along the length, tie the other end to the tensioner on the end post at the other end, and tighten the tensioner;

Step 5. Fix the columns: Use prefabricated column rods as diagonal supports to fix the end columns. The diagonal supports should be parallel to the mesh surface, and the angle with the ground should be 40° to 50°. The diagonal supports and end columns should be fixed with wire binding. The diagonal support foundation Should be consistent with the dimensions of the end column foundation.
