The pneumatic down-the-hole hammer drill from Button Bits suppliers has a diameter of 1 meter. Compared with traditional rotary drilling rigs, it has the characteristics of high hole formation rate, fast construction speed, good moving performance, low weight on bit, and low equipment loss. The combination of the drilling rig and the pneumatic down-the-hole hammer method overcomes the industrial problems of slow construction efficiency in hard rock formations and fast drilling tool wear. It can drill more than 4 meters in an hour, and the construction efficiency is 8 higher than that of conventional large-tonnage rotary drilling rigs. Times more.

The Qinglian Railway is an important part of my country's "five vertical and five horizontal" comprehensive transportation corridors along the north-south coastal transportation corridor, and has important significance and role in the national economy and road network. The line starts from Qingdao North Railway Station and ends at Shiqiao Station on the Lianyungang Railway connected to Lianyungang City, with a total length of 194.513 kilometers and a design speed of 200 kilometers per hour. It is scheduled to be opened to traffic simultaneously with the Jiqing High-speed Railway at the end of 2018. After completion, the history of no traffic in sunshine will end, and the travel time from Qingdao to Shanghai can be shortened from 7 hours to 4 hours.

The pneumatic down-the-hole hammers of Water Well Drilling Tools suppliers can be used in solid mineral exploration, placer deposit exploration, engineering geological survey and water well drilling construction, etc., but also in blast hole construction, anchoring and grouting engineering construction, and foundation engineering Construction and mine shaft construction, etc. Of course, it is also used in some other fields, such as drilling horizontal holes in the construction of underground tunnels using the pipe shed method, laying underground pipelines, and planting buried wire rods.
