The anchor drilling rig is mainly used in hydro power stations, railways and highways, in order to prevent and control various geological disasters, anchoring operations are carried out on landslides and dangerous rock masses.It is mainly used in landslide and dangerous rock anchoring projects in tunnels, railways, highway slopes and other kinds of geology, especially for high slope rock anchoring projects. Drilling operations consume less manpower and material resources, have high construction efficiency and high safety factor. It is also suitable for the construction of deep foundation pit support, reinforcement hole for anti-float anchor and foundation grouting, blast-hole in blasting project, high pressure sprinkling stake and tunnel pipe support hole, etc..

Maxim Nagachev, director of the Russian Central Institute of Automotive and Engine Science (NAMI), revealed on the 31st that Russia is expected to increase its imports of Chinese-made cars in the next few years.
On the 31st, in the framework of the APEC summit chaired by Russia, Nagachev chaired the dialogue meeting for the automotive industry in St. Petersburg. Representatives of APEC economies officials and senior industry officials attended the meeting.
He said: "The goal of China's 13th Five-Year Plan is that by the time 2020 China produces two cars each, there should be one sold abroad. Considering that Russia is becoming the leading European market, it is clear that we will be included in the list. China's target list."
Nagachev pointed out that China currently produces about 20 million cars each year, and its export share does not exceed 3%. He did not make predictions on which Chinese car models might be the most marketable in Russia.
Nageev said that this year China has exported over 100,000 cars to Russia, which has doubled from last year.
The drilling technology with casing of anchor drilling rig is designed to solve the problem that complex rock layers cannot be holed. The drill bit impacts rock continuously, and the broken rock is blown to the ground by the air pressure discharged from the gap between the casing and the drill pipe. The drill pipe and bit can be lifted after punching the hole, and the casing is placed in the middle of the rock layer, so that the rock layer doesn't collapse.
