Tunneling & Underground Project

TBM cutters, Top hammer drilling tools and raise boring cutters for Tunnelling & Underground Engineering

Every tunneling and underground engineering construction requires the cooperation of multiple types of equipment. We can provide safe, high-efficiency, and high-precision rock tools consumables for rock drilling and breaking. Litian TBM cutters can be adapted to all kinds of tunnel boring machines to complete tunnel excavation work under various rock conditions. Litian top hammer rock drilling tools can be adapted to all kinds of underground rock drilling rigs to complete precise rock drilling operations. Litian raise boring cutters can be adapted to all kinds of raise borers to complete the construction of various pilot shafts and ventilation shafts.

In different tunneling and underground engineering, the physical properties of rocks (such as density, humidity, magnetism, swelling, dissolution) and mechanical properties of rocks (such as strength, hardness, abrasion, brittleness, toughness, robustness) are differ in thousands of ways. In the development of TBM cutters, Top hammer drilling tools and raise boring cutters, we not only carry out development in raw materials, heat treatment, and manufacturing technology, but also produce rock drilling tools chinaand excavation tools in accordance with the different characteristics of the rocks.

In order to meet the standards of safety, speed, accuracy during drilling and excavation, the parameters of our underground boring toolsand drilling tools can be fully matched with the host machine to achieve the best working conditions and complete the work tasks more efficiently.

After years of accumulation and development, Litian hard rock drilling toolshave been widely used in various tunnel construction projects and underground engineering, such as metro, railways, road tunnels, harbour tunnels, water diversion projects, sewage treatment projects, outfall projects, underground pipeline projects, etc. We have participated in many large-scale projects at home and abroad, such as Hanjiang to Weihe River Project, ABH Water Transmission Tunnel Project, Peru San Gaban hydropower station tunnel project, and so on.
