1. Self-propelled anchor structure
Self-propelled anchor consists of carbide drill bit, hollow fully threaded anchor body, stopper plug, backing plate, nut, connecting sleeve, etc. The structure is an anchor rod structure in which a carbide drill bit is installed on the head of the rod body and drilled directly for grouting without taking it out.
2. Characteristics of self-propelled anchors
.
This is the best construction plan for complex geological conditions such as broken surrounding rock, weak surrounding rock, high ground stress and large deformation. It avoids the risk of collapse due to The impact of holes on construction.
.
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.
.
The grouting is full and pressure grouting can be realized to improve the quality of the project.
.
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 body, avoiding the risk of rust and achieving the purpose of long-term support.
.
Easy to install, no need to process threads on site, you can easily install backing plates and nuts.
3. Self-propelled anchor construction method
Self-propelled anchors are mainly used in complex geological conditions such as broken rock formations, weak surrounding rocks, high ground stress and large deformation, for support, rescue, and collapse control. In all situations of self-drilling grouting, it has a wider scope of application and higher functions. It installs a carbide drill bit on the head of the hollow anchor body, and uses the anchor body instead of the drill rod for drilling. The drill tail connecting rod connects the anchor body and the rock drill. After the rock drill drills the hole to the designed anchor depth, it is installed. After grouting plugs, backing plates and nuts are installed, grouting is carried out. When in slope support or hydropower station construction, large-diameter anchor rods can also be used instead of down-the-hole drill pipes for drilling and grouting. They are more powerful, stronger than anchor cables, faster and more convenient, and have lower construction costs.
