Hollow anchor product description:

Anchor rod refers to an elongated rod body that penetrates into the interior of the rock and soil and controls the deformation of the rock and soil. It can include parts such as a backing plate and a nut. Anchor rod is a tensile member that penetrates deep into the ground. Its one end is connected to the engineering structure and the other end is deep into the ground.

Hollow Anchor Product Details

Hollow Anchor Product Introduction

Anchor rod refers to an elongated rod body that penetrates into the interior of the rock and soil and controls the deformation of the rock and soil. It can include parts such as a backing plate and a nut. Anchor is a tensile member that penetrates deep into the ground. One end is connected to the engineering structure and the other is deep into the ground. The entire anchor is divided into a free section and an anchor section. The free section refers to the transmission of the tensile force at the anchor head to the anchor body Area, whose function is to apply prestress to the anchor rod; the anchorage section refers to the area where the cement slurry binds the prestressed tendons to the soil layer, and its function is to increase the bonding friction between the anchor body and the soil layer and increase the anchorage. The pressure of the body transmits the tensile force of the free section to the depth of the soil.

The anchor body is a grouting pipe. After pressing the grouting fluid, the rod body can not only be anchored, but when the grouting pressure is high, part of the grout will penetrate into the fissures of the anchor hole to strengthen the surrounding rock. Sliding plugs and exhaust pipes shall be provided on the upward-sliding hole.

How to use hollow anchor

It is mainly used for system support of surrounding rock with moderate geological conditions.

In the case of hard rock, horizontal bedding, joint cracks, open mud, or groundwater development, early support can be quickly formed through steel expanded shell anchors to control the deformation of the surrounding rock to ensure the stability of the surrounding rock and then grout for long-term anchoring. After drilling a hole with a rock drill to the designed anchor rod depth, install the steel anchor head on the anchor rod body, place it in the hole, install the stopper, pad, and nut, and then reverse the anchor rod to open and expand the shell anchor head. Hold the hole wall and grout.

Hollow anchor

1. Quick initial support to control deformation of surrounding rock and ensure stability of surrounding rock.

2. The hollow design enables the anchor rod to realize the function of the grouting pipe and avoids the mortar loss caused by the traditional construction process when the grouting pipe is pulled out.

3. The grouting is full, and pressure grouting can be realized to improve the quality of the project.

4. Due to the function of various accessories, the center of the rod is very good. The mortar can wrap the anchor body over its entire length, avoiding the danger of corrosion and achieving the purpose of long-term support.

5. Easy installation, without the need to process the thread on site, you can easily install the pad and nut.

6. Combined with the special bolt pump and grouting technology, it solves many problems of traditional anchoring and support.
