Background

Conventional rock bolts are the most basic components of roadway supports in mines, and reinforce the surrounding rock of the roadway. The conventional anchor rod is not only used for mining, but also used in engineering technology for reinforcing a deep foundation pit anti-pulling anchor, preventing and treating a side slope and treating a landslide, and actively reinforcing underground engineering such as tunnels, underground rail transit and the like.

The anchor rod must be composed of several factors: 1. the tensile strength of the anchor rod body is higher than the friction force of the rock-soil body; 2. the bottom end of the anchor rod body can be in close contact with a rock-soil body to form frictional resistance; 3. the top end of the anchor rod body, which is positioned outside the rock-soil body, can resist the radial resistance of the rock-soil body.

The anchor rod is used as a tension member penetrating into the stratum, the top end of the anchor rod is connected with an engineering structure, the bottom end of the anchor rod penetrates into the stratum, the whole anchor rod is divided into a free section and an anchoring section, the free section is used for transmitting the tension of the anchor rod head to an anchoring area, and the function of the free section is to apply prestress on the anchor rod; the anchoring section is an area where the anchor rod is bonded with the soil layer by cement paste, and has the function of increasing the bonding friction effect of the anchoring body and the soil layer, so that the bearing effect of the anchoring body is increased, and the tensile force of the free section is transmitted to the deep part of the soil body.

The construction process of the anchor rod generally comprises the steps of firstly drilling a hole, then placing a rod body of the anchor rod into the drilled hole, and then grouting; the anchor rod body is placed in the drilled hole, and how to ensure that the anchor rod body is positioned in the central position of the drilled hole is avoided, so that the anchor rod often extends into a rock-soil body at a certain included angle, and the anchor rod is very important to be fixed in the correct position. In some underground engineering, a mortar grouting method is also needed for soft foundations, so that special requirements are required for anchor rod design, anchor rod devices and manufacturing, and therefore an anchor rod positioning device with good positioning effect and convenience in mounting/dismounting is needed.

For example, patent application No. CN202220512257.5 discloses an anchor locator, which includes a bracket and a plurality of legs; a through hole for the anchor rod to pass through is arranged in the middle of the support in a penetrating manner, and the support is detachably arranged on the anchor rod; the support legs are arranged at intervals in the circumferential direction of the support, each support leg is arranged in a telescopic mode, one end of each support leg in the telescopic direction is fixedly connected with the periphery of the support, and the other end of each support leg is used for abutting against the inner side wall of the drilled hole so as to position the anchor rod in the drilled hole. This scheme is through establishing the support sleeve on the stock surface to put this fixer at the opening part of drilling, move the stabilizer blade through twisting after that and make its stretch and contract and inconsistent with the drilling wall, and then realize the fixed to this fixer, but because be provided with a plurality of supporting legss on the device, need adjust in proper order, and can only judge whether the stock is located the drilling center according to the manual work during the regulation, can't fix a position the stock fast.
