Compared with the anchor bolt, the cable bolt has the characteristics of large depth, high strength, and large pre-tightening force. The construction of resin cable bolt is similar to that of rock bolt in many aspects. Cable bolt price.

The cable bolt should be supported in time with the excavation face. The construction process of anchor cable bolt support is to fix the hole position of the anchor cable bolt, drill the hole for the anchor cable, clear the hole, load the resin coil into the drill hole, use the head of the anchor cable to support the resin coil and send it to the bottom of the hole, and then lift the hole. Pull up the drilling rig and connect the drilling rig and the tail of the anchor cable bolt with the agitator, start the drilling rig to stir the resin coil for the specified time, stop stirring and wait for the specified time, shrink the drilling rig and remove the agitator, wait for 10-15 minutes, put on the support plate to install the anchor, and use the tension Pull the equipment tension anchor cable to the design preload.

In the construction process of anchor cable bolt support, drilling, mixing resin coil and tensioning are the main processes.

1. Drilling

Use the anchor rod (cable) drilling rig to cooperate with the extended drill rod and drill bit to drill. In order to simplify the drilling equipment, one kind of drilling rig should be used to drill the anchor rod and anchor cable. The strength of the joint of the extended drill pipe is low, and the drilling propulsion should be controlled before the joint enters the hole to avoid the broken section of the drill pipe. The drilling rig should be constructed in strict accordance with the designed hole position, hole depth and angle, and the error should be controlled within the design requirement range.

2. Install the anchor cable bolt.

The installation process of the resin anchor cable bolt is similar to that of the anchor rod, including loading the anchoring agent, inserting the cable body, stirring the resin anchoring agent, and waiting for curing.

1) Install resin anchoring agent. According to the type, quantity and sequence of resin anchoring required by the design, they should be loaded into the drilled holes in sequence. Cable bolt price.

2) Insert the cable body. A special stirrer is installed at the tail of the anchor cable, the end of the cable body is inserted into the drilled hole with resin anchoring agent installed, and the resin anchoring agent is slowly sent to the bottom of the hole.

3) Stir the resin anchoring agent. The tail of the anchor cable is connected to the drilling rig with a special mixer to start mixing. Slow first and then fast. After all the anchor cables are inserted into the drilled hole, use full-speed rotation and stir until the specified time. Wait a certain amount of time after stopping stirring, retract the rig, and remove the agitator. The exposed length of the anchor cable after stirring should be controlled within the design range.

3. Tension anchor cable bolt

After waiting for 10-15 minutes, install joists, pallets and anchors, and use tensioning equipment to tension the anchor cables to the design preload. Then remove the jack. Cut the exposed part of the anchor cable with a hydraulic cutter. Cable bolt price.
