Split Fixing Bolts For Underground Mining
Advantages of split fixing bolts
1. Convenient installation: split fixing bolts have a simple structure and are easy to install and dismantle without adjusting the length of the bolts.
2. Convenient maintenance: as the bolt and nut can be separated, it is more convenient to maintain or replace the bolt, and it is not easy to damage the connecting parts.
3. High temperature resistance: Split fixing bolts are usually made of high-quality materials with good high-temperature resistance, suitable for use in high-temperature environments.
4. Strong load-bearing capacity: the design of split fixing bolts is more reasonable, can better withstand the pressure and tension between the structural components, and has a strong load-bearing capacity.
5. Good anti-seismic performance: Split fixing bolts are firmly connected, not easy to loosen, with good anti-seismic performance, suitable for projects requiring anti-seismic requirements.
Split Bolt Set Description:
1. Split Bolt (Bolt): mainly responsible for connecting structural components, usually made of high-strength metal materials with certain tensile and torsional strength.
2. Nut (Nut): used to fix the position of the bolt, usually made of metal materials, need to be used in conjunction with the bolt when connecting.
3. Washer: Used to increase the connection area, dispersing the connection pressure, preventing damage to the structural parts, usually made of metal or plastic materials.
4. Locking Device: Used to prevent bolts from loosening during vibration or work, usually in the form of spring washer, nut locking piece.
5. Elastic Washers (Spring Washer): Used to provide the degree of elasticity of the connection, not only to prevent the threads from loosening, but also vibration damping.

Installation requirements of sewing tube anchor:
In accordance with the reinforced mortar anchor, it is generally divided into two types of construction process: first grouting and then anchoring and first anchoring and then grouting, first grouting and then anchoring construction method, we should pay special attention to the occurrence of leakage of the quality of the grout problem in the installation, while first anchoring and then grouting construction method, we should pay attention to the problem of grouting and exhausting, or else it will be easy to produce a situation where the grout is not full, and this will directly lead to the anchoring effect is not good. The main role of the sewing pipe anchor is to restrain and reinforce the soil body, which can not only make up for the lack of tensile and shear resistance of the soil body, but also the anchor in the process of grouting construction, the cement slurry can penetrate into the internal fissures of the geotechnical body, and through the reinforcing effect of cement slurry on the geotechnical body, it can improve the structural strength of the geotechnical body itself.
Prestressing anchor installation, after the anchor head is anchored inside the anchor, the outer anchor end is tensioned with jacks, and about 10t of pre-tensioning force is added to each anchor, and the bolts of the pad plate at the end of the rod are tightened, and the whole length is grouted with cement mortar.
