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.
