With the coming of summer, the rainstorm is following on. Most places in China begin suffering the flood disaster and Wuhan encountered a big one this summer.
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.
But in Wuhan, the transformation of the old town is not easy. There are various pipelines underground, including the communicant, electrical, fuel gas, industrial and so on, they may connect with many apartments, so the construction is difficult and the financial affair is big.
There are many advantages in Wuhan: the water area occupies 25%, the afforested area is 39.7%, 166 lakes and 165 rivers, they can store water, but at the aspect of drainage, when it rains heavily and the water level is lifted, Wuhan has not a little advantages.
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.
The anti-corrosion rock bolt can prevent the erosion of water, oxygen, chloride and other corrosive medium by forming a coating, it can reach the good result of corrosion prevention.
IMT bolt 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 filed hole.
Besides, the rock drill and injection pump are all good for the construction of drainage.
