  The basic common sense of the maintenance of the hollow grouting anchor rod price: the comparison between the mine anchor rod and the traditional metal material anchor rope has irreplaceable advantages. In terms of characteristics, the rod body is easy to be laser cut, which has the maintenance effect on the shearer blade; the explosion-proof type is antistatic, and it is not easy to cause flames during laser cutting. It is extremely beneficial to the construction of coal road safety engineering and is very suitable for areas with high coalbed methane concentration values.

Hollow grouting anchor

  High-strength corrosion resistance, heavy and easy to operate, the net weight is only 1/4 of the steel anchor cable of the same specification and model. It can be conveniently used in narrow indoor spaces such as tunnel construction and coal mines, making engineering construction easier and reducing labor The efficiency and price are lower than that of metal anchor cables, which can reduce the cost of anchor support by 10%. The price of hollow anchors, the price of hollow grouting anchors, and the analysis of the construction requirements of hollow anchors

  Hollow grouting anchor price, the hole spacing must be measured according to the design plan before construction, and the hole spacing must be marked on the surface of the slope; before the construction of the project, the pull test must be carried out in strict accordance with the design plan, and be carefully done Test description: The hole drilling of the anchor cable must meet the requirements of the design plan. After the pile is formed, the wall should be protected by mud and the anchor cable should be installed immediately.

  The anchor rod body should be flat, rust-proof and degreasing. The anchor cable equipment must be positioned vertically and accurately, and equipped with a grouting pipe. The length of the grouting pipe cannot be less than the length of the anchor cable. The grouting pipe cannot be dragged or pulled out during the whole grouting process; the anchor cable grouting adopts the hole bottom backflow grouting method , The compressive strength of cement mortar, the water-cement ratio of concrete, and the working pressure of grouting should meet the requirements of the design plan; the anchor cable building reinforcement should be placed in the grid beam according to the design plan, and be mechanically connected with the grid beam reinforcement. Concrete should be poured immediately at the end of the connection.
