Yichen is mainly engaged in drum cutters manufacture. The Yichen drum cutters are used for applications such as digging trenches for laying pipelines, cables or drainage, tunnel construction and digging mine shafts. The powerful drum cutter also offer superior usability in demolition and renovation of buildings. Drum cutter used to dig tunnels is one of the most common applications.
Tunnel construction has always been the peak of construction projects, and construction is difficult. Before the 1960s, a combination of drilling and blasting was used to build tunnels. The disadvantages of this method are very obvious, the safety of blasting is unknown, a large amount of pollution is generated, and the shape of the blasted tunnel is irregular, which cannot be precisely controlled. After the 1960s, the level of tunnel mechanization construction has been greatly improved, and the use of drum cutter has completely changed the drilling and blasting method of tunnel excavation.
It is very common for drum cutter used to dig tunnels. The drum cutter has precise construction and is driven by hydraulic technology. The cutter teeth on the cutter drum collide with the construction surface and cut the soil and rocks like sharp claws, providing a new and economical construction method for tunnel excavation. When the interior of the tunnel is sandstone, sedimentary rock, and siltstone, the daily excavation speed of the drum cutter is about 10 meters, and the milling efficiency is very high. With the help of Yichen drum cutter, the tunnel construction project was completed in 40 days, which greatly shortened the construction period.
