Self drill anchor is an advanced anchor system, it is more safer for operator. The plastic sealing element is used to seal the hole and prevent leakage of grout or resin, ensuring a complete filled hole.
Nowadays, as the acceleration of urban construction, the district range and population density become larger and larger, if we don’t enlarge the degree of the drainage construction, the old pipeline has not adapted with our society, so the drainage tunnel in Wuhan is necessary.
By the analysis of the disadvantages of Wuhan drainage, building a tunnel is quite suitable. While because the various pipelines are underground 8 meters and the subway is underground 8-40 meters, the digging of drainage should be underground 45 meters.
The self drilling anchor bolt can be used to put drilling, grouting and anchoring together, it is simple to install and operate, and it is safe, reliable and time saving.
To improve the entire capacity of production, the ancillary facilities are also used. Rock drill adapts to the conditions with hard rock of f=8-18. Anchor net prevents the collapse and injection pump are used with rock bolt system to ensure the effect of permanent anchoring.
