Slope protection network is generally divided into active protection network and passive protection network, and the price depends on the material of slope protection network and the site where it is installed. The price of active protective net is relatively cheap, generally around 60-80 yuan /m2. Passive protective nets are expensive, generally around 160-240 yuan /m2. Because the mesh of the passive protective net is generally less than 250mm, the passive protective net is supported by I-shaped steel columns, so it is more expensive. Of course, the above price includes all the material prices and installation prices.

Reasons for setting up slope protection net

1, the foundation under subgrade is unstable natural sliding body;

2. The slopes on both sides of the highway are too steep;

3. The method of slope filling embankment is wrong;

4. Too wet soil reduces cohesion and internal friction;

The foot of the slope was washed away by the water.

6. After the completion of expressway, the stability of rocks in some areas was destroyed, especially the strata tilted in the cutting direction, which led to water or earthquake damage.

7. The rock structure and composition of the mountain on both sides of the highway are unstable.

8. Damage caused by debris flow.

Product characteristics

It has high flexibility, high protective strength and easy spreading. Adapt to any slope terrain, and the installation procedure is standardized and systematic.

The system adopts die-cutting installation mode, with short construction period and low cost.

The special manufacturing technology and high anti-corrosion and anti-rust technology of system materials determine the ultra-high life of the system. The system can minimize the impact of the construction team on the environment, and its protected area can fully protect the stability of rock and soil, which is convenient for artificial greening and beneficial to environmental protection.

The soft steel rope net system is used to cover the dangerous rock and rockfall slope, and its 16 bracing and 16 transverse supporting ropes are staggered by 4.5mx4.5m. In the actual construction, it can be used as a pole in a square form of 4.2 m to 4.8 m according to the terrain conditions, and a 4mx4m D0/08/300 steel rope is laid in each 4.5 mx4.5 m grid composed of ropes. Each net is connected with the surrounding supporting ropes through ropes and is pre-tensioned. This pre-tightening technology can make the system exert a certain normal pre-tightening force on the slope, thus improving the stability of dangerous rock mass on the slope and preventing the occurrence of falling rocks. At the same time, S0/2.2/50 mesh with small mesh shall be laid under the steel rope mesh to prevent small-inch stones from falling.
