2015

In 2015, according to different geological conditions, new materials were used and new processes were developed, which greatly improved the wear resistance and toughness of the products. Expand the development and production of TBM cutter head accessories, soft ground cutters and other products.

2016

In 2016, the one-stop production line of annealing, machining, carburizing, straightening and surface strengthening of rock drilling tools was put into use. Litian has become long-term cooperation unit with domestic heavyweight construction units such as CRCHI, CSIC, China's hydropower construction bureaus, and has established product service stations in many places.

2017

In 2017, Litian became the largest supplier of hard rock TBM cutting tools in China.

2019

In 2019, Began to develop and produce raise boring tools.

2020

In 2020, the Second factory in Huludao was completed and put into use. At the same time, the raise boring cutters have been successfully applied to mining projects with good results.

According to the comparison of No. 36 Simba H1354 trolley using different brands of drill rods and drill button bits, Litian drill rods have a longer service life, and Litian drills have better drilling speeds, better slag removal effects, and long service life. In particular, the service life of the drill bit with 14 buttons is greatly improved compared to other brands.

China Railway Tunnel Group One Co., Ltd.

China Railway Tunnel Group One Co., Ltd.

Shenzhen Beihuan Cable Tunnel Longzhu Section Shield Engineering Project Department

Litian rock tools have been used in our project with remarkable results, and the cost performance is better than other brand rock tool quality. Litan provided rock tool maintenance work and provide professional technical services and technical guidance for our project.

Geological conditions: It is an uneven stratum with the upper part soft and the lower part hard. The upper part of the interval is hard plastic cohesive soil and residual soil, and the lower part is fully and strongly weathered granite. The lithology of the tunnel section is quite different. There are generally 60m long bedrock protrusions in the interval, and the bottom protrusions are medium and lightly weathered granite, which intrude into the tunnel 0.5m-1.1m. The uniaxial compressive strength of the slightly weathered granite rock is as high as 120Mpa. The rock is very hard and extremely difficult to break.

Civil Engineering Project Manager Department

In the second phase of Chongqing Rail Transit Line 9, the total length from the right line of the TBM section is 1962 meters. Litian TBM roller cutters have been tunneled for 1746 meters in this project. The tunneling thrust is usually 8000KN and the maximum thrust is 12000KN. The TBM cutters' performance is excellent during use, and the cutting tools are not replaced. There are no abnormal damages such as partial wear and disc cutter ring breakage, and the average wear is 1-3mm.
