Rock Bolt Types

Product Description：

Rock anchor bolts are essential components in the construction industry, providing reliable support and reinforcement for rock structures. With various rock bolt types available, including friction rock anchor bolts, these products offer versatile solutions for different project requirements. Rock bolts enhance the stability and structural integrity of rock formations, ensuring safety and durability in tunneling, mining, and construction applications. Friction rock anchor bolts, in particular, are designed to deliver powerful anchorage in challenging squeezed ground conditions, making them ideal for demanding projects. Whether it's for securing rock slopes, stabilizing tunnels, or reinforcing underground excavations, rock anchor bolts play a crucial role in maintaining the structural stability of rock formations and protecting workers and assets from potential hazards. Trust in rock anchor bolts for effective and long-lasting rock support solutions.

Specification

Slit Tube Anchor Description

1、Good supporting effect. Anchor support in the support principle in line with modern rock mechanics and rock control theory, belongs to the “active” support. After the installation of the anchor, it reinforces the surrounding rock inside the surrounding rock, and quickly forms an overall bearing structure of the surrounding rock a protection, so it can mobilize and use the stability of the surrounding rock itself, give full play to the bearing capacity of the surrounding rock itself, and effectively control the deformation of the surrounding rock of the roadway, so the anchor support is more conducive to the protection of the stability of the surrounding rock of the roadway, and improve the maintenance of the roadway.

2、Low labor intensity and high efficiency. Compared with the traditional shelf support, because the support material used in anchor support is less, lighter weight, roadway excavation, reducing the amount of support material transportation, labor intensity is also greatly reduced, and is conducive to improving the efficiency of excavation. When the working face is being mined back, it also eliminates the retraction work of the steel scaffolding, which not only reduces the labor intensity of workers, but also improves the safety factor.

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.
