Hollow grouting bolt is mainly composed of grouting stopper, backing plate, nut, hollow bolt body, grouting channel, slurry outlet channel, exhaust channel, connecting section, solid bolt body, anchor head, etc. Because the slurry outlet channel of hollow bolt is located on the connecting sleeve, the transportation of materials can be brought into full play, which has great implementation value and social and economic benefits. how do rock bolt work

Characteristics of hollow grouting bolt

The hollow design makes the anchor realize the function of grouting pipe, and avoids the mortar loss caused by pulling out the grouting pipe in traditional construction technology.

Grouting is full, and pressure grouting can be realized to improve the engineering quality. how do rock bolt work

Due to the function of each fitting, the center of the rod body is very good, and mortar can wrap the whole length of the bolt body to avoid the danger of corrosion and achieve the purpose of long-term support.

It is convenient to install, and it is convenient to install base plates and nuts without processing threads on site.

Combined with the matching grouting pump and grouting technology, the anchoring system has solved many problems of traditional anchoring support.

Construction method of hollow grouting anchor rod. how do rock bolt work

It is mainly used for systematic support of surrounding rock with medium and good geological conditions. After the anchor rod is drilled to the designed depth of the anchor rod, install the stop anchor head on the anchor rod body, put it into the hole, and then carry out grouting. Ordinary hollow grouting bolt can improve the engineering quality, facilitate the construction, and achieve good results in the rock strata where anchoring is needed.
