The characteristics of the active protection net have high flexibility, high protection strength, easy fusion, and can be integrated into all slope landforms. The program installation is standardized and professional. The quality is overall, so that the artificial slope and the original natural slope will not be separated, collapsed, etc., and as time goes by, the increasingly strong vegetation root system will make the slope structure more reliable and firm, and the raw materials The unique manufacturing process and high anti-corrosion and anti-rust treatment technology determine a very high service life, and its protection area can fully protect the firmness of sand and rock, which is convenient for artificial landscaping and beneficial to environmental protection. The damage to the natural environment has been reduced to a minimum. This article briefly introduces the construction steps of the active protection net.

1. The slope needs to be cleaned before the installation of the active protection net

Slope protection and remediation: Slope surface finishing Completely clean up the slope surface from top to bottom, remove all floating soil and loose stones on the slope surface, and properly reinforce part of the terrain to prevent falling rocks from hurting people during construction. Use foreign shovels, steel drills, etc. to remove or temporarily treat floating soil and pumice that affect construction safety in the slope protection area, so as to eliminate construction safety hazards.

2. Locate on the anchor hole of the active protection net

Measure and locate the bolt hole position according to the planned position combined with the actual terrain on the site. Due to the ruggedness of the slope, considering the safety of the operation on the slope and the characteristics of the drilling depth and hole diameter, the system engineering drilling machine adopts a hand-held pneumatic drill , corresponding to the rock and soil area, use a hand-held electric drill. In order to meet the design requirements, use a 42 (mm) drill bit (design not less than 42mm), use a 3.5m drill pipe for an anchor hole with a depth of 3m, and use a 4.5m drill pipe for a 4m anchor hole. Drilling rods to ensure that the depth of the anchor rod entering the rock mass is not less than the planning requirements. According to the terrain conditions, the hole distance can be adjusted by 0.3m, otherwise, the support rope and the protective net may not be connected.

3. Excavate the anchor rod and clear the hole

After excavating the pits of the bolt holes and drilling the bolt holes and positioning the bolt holes, first dig a pit at each hole with a depth less than the length of the exposed ring of the bolt, so that the system can be installed as close as possible to the slope. . According to the planned length of the bolt, drill the bolt hole on the vertical slope rock surface, drill the bolt according to the planned depth and clean the hole, and the hole depth should be longer than the planned length of the bolt.

4. Install vertical and horizontal support steel ropes

After the support rope is tightened, the two ends of the support rope are clamped with wire rope clips to form a criss-cross grid. The galvanized steel wire rope anchor is selected, and its standards and performance parameters are inspected by the manufacturer before leaving the factory. A small amount of sampling.
