Take a look at the key words pneumatic hammer drill
Recently, the XCMG XR150DV DTH Drilling and Drilling Rig was constructed on the Qinglian Railway Project (line from Qingdao to Lianyungang) and exhibited different brilliance. It can drill more than 4m in one hour and the construction efficiency is increased by more than 8 times. The successful application of engineering methods has created a precedent for the hard rock construction of rotary drilling rigs equipped with pneumatic DTH hammers.

Look at the details of product construction
The maximum drilling diameter of Xugong XR150DV is 1.2m, and the maximum drilling depth is 46m. It adopts retractable crawler chassis, main hoist single row rope structure, special power head damping mechanism, adjustable vise clamping structure, automatic telescopic protection Dust devices, four-fold rate goose head lifting mechanism, etc., ensure the safety of equipment, environmental protection, and efficient construction.
XCMG XR150DV Pile Formation in Construction of Qinglian Railway Project
The Qinglian Railway Project has 1m pile diameter, 21m pile depth, and 2m below the surface is an andesite with very high hardness. It uses XCMG XR150DV type pneumatic DTH hammer rig to combine the rotary drilling rig with the pneumatic DTH hammer method and uses the DTH hammer. The principle of impact crushing crushes hard rock, conquering the slow construction efficiency of hard rock strata, and the industrial problems of rapid drilling wear.
XCMG XR220DIV Pneumatic DTH Hammer Rotary Drilling Rig Construction in Victoria Harbour, Hong Kong
As early as 2015, Xugong Pneumatic Drilling Drilling Rig XR220DIV, XR180DIV was used in batches for Hong Kong and was used in building foundations, subways, bridges and other construction projects. In the construction of the Hong Kong MTR middle line at the time, Victoria Harbour The tender section is the core project of the entire subway line. The tender section is hard and complex. The designed pile diameter is 813mm, and the rock is 20m. The hardness of the bedrock is very high. The average drilling depth per hour of the XCMG DTH rotary drilling rig is 6 to 8m, greatly improved the construction efficiency. Xugong's pneumatic DTH Drilling Rotary Drilling Rig construction stopped the history of the construction of rotary drilling rigs in Hong Kong, making XCMG the only mainland-made rotary drilling rig brand that entered the high-end market in Hong Kong at that time.
