The price of Grouting Rock Bolts Anchor Cable is reasonable
Anchor cable means that when the main cable is anchored in the side hole of the suspension bridge, the main cable should be divided into many strands of steel bundles respectively anchored in the anchor ingot, and these steel bundles are called anchor cables. The outer end of the anchor cable is fixed on the slope surface, and the other end is anchored in the stable rock mass within the sliding surface through the prestressed steel strand wire of the slope sliding surface, which directly generates anti-sliding resistance and anti-sliding friction resistance on the sliding surface, so that the structural plane is in a state of compression, so that the integrity of the slope rock mass and the mechanical properties of the rock mass can control the displacement of the rock mass and promote its stability. To achieve the purpose of regulating bedding, landslide, dangerous rock and dangerous rock.
Anchor cable installation
Before loading the anchor cable holes, check whether the anchor cable number is the same as the hole number, and after confirming that it is correct, then clear the hole with high pressure air, that is, start to install the anchor cable.
Installing a downdip anchor cable is relatively simple and does not have many problems. The following four points should be paid attention to when installing the uptilt and horizontal anchor cable: check the location of the stop ring and the limit ring, and replace the damaged ring as required; Check the position and flow of the exhaust pipe; The anchor cable is sent into the hole, when the positioning ring reaches the hole, stop pushing, install the grouting pipe and one-way valve; After the anchor cable is installed, check whether the exhaust pipe is smooth. If it is not smooth, pull out the anchor cable and send the cable again after the fault occurs.
Grouting Rock Bolts Anchor Cable composition
The hollow grouted anchor cable is composed of hollow bolt body, anchor head, stop plug, backing plate and nut.
1. Hollow bolt body The bolt body adopts hollow design, and the middle hole of the bolt body is used as the high-pressure geomancy channel and the grouting channel. Compared with the solid rod body, the hollow rod design can obtain better steel degree and shear strength. The external surface of the bolt is a full-length standard large-pitch thread structure, which is convenient for cutting and lengthening the bolt, and increases the bonding area between the bolt body and the grouting material compared with the smooth slide rod body, thus improving the anchoring force.
2. Anchor head The anchor head adopts steel anchor head, which can not only fix and center the bolt body components but also produce a certain anchoring force in the rock anchor hole.
3. The grouting plug is made of rubber and plastic materials, considering the grouting exhaust, and has a certain sealing effect, which is easy to achieve pressure grouting and increase the fullness and compactness of the grouting material. The stop plug has the effect on the center support.
4. The pad adopts hot-rolled forming pad, which has certain elasticity and is easy to transfer stress. The backing plate provides an adjustable Angle of 7 degrees for easy adhesion to the rock surface.
5. The nut adopts a hemispherical or hexagonal nut, through which active stress can be applied to the rod body.
