High Quality High Strength Full Threaded Steel Self Drilling Anchor Bolt Hollow Anchor/Hollow Anchor Bar / Anchor Rods for Mining Industry

Zhengde The hollow anchor consists of five parts: hollow drill pipe, plastic drill bit, grout stopper, backing plate, and nut. The drill bit is made of engineering plastic and is equipped with slurry holes and dust removal.
Application scope:
1. Radial reinforcement: Hollow anchors replace traditional mortar anchors for radial reinforcement, which can completely solve many defects such as incomplete grouting and inability to achieve pressure grouting during the construction process of traditional mortar anchors, ensuring the quality of the project.
2. Slope reinforcement: Using hollow anchors to reinforce unstable slopes not only has a simple process and low cost, but also is convenient and quick to construct and has remarkable effects.
3. Foundation pit support: Hollow anchors are used to reinforce foundation pits of buildings, which not only has a simple process, but also can realize pressure grouting and improve the surrounding rock conditions of foundation pits.
structure:
The hollow anchor consists of a hollow fully threaded rod body, anchor head, grout stopper, backing plate, nut, etc. Each part of it is designed to maximize the cost of filling and dense filling during grouting. The mortar can be up to dozens of times. Kilograms (specific parameters are subject to design) penetrate into surrounding rock cracks under pressure, and backing plates and nuts can be easily installed.
Features:
The hollow anchor combines the functions of the anchor and the grouting pipe into one. It is a grouting pipe during grouting, and it becomes an anchor rod without pulling it out after grouting. Compared with traditional anchoring technology.
1. The hollow design allows the anchor to function as a grouting pipe, avoiding the loss of mortar caused by pulling out the grouting pipe in traditional construction techniques.
2. The grouting is full and pressure grouting can be realized, which improves the quality of the project.
3. Due to the role of various accessories, the centering of the rod body is very good, and the mortar can wrap the entire length of the anchor rod, avoiding the risk of corrosion and achieving the purpose of long-term support.
4. Easy to install. Backing plates and nuts can be easily installed without on-site processing of threads.
5. Combined with the supporting special grouting pump and grouting technology for anchor rods, it is currently the only anchor system in China that has completely solved many problems of traditional solid support.
