This hot summer, Tyheng low headroom KR285CS contributed to the Quanzhou High-speed railway station expansion project

Quanzhou High-speed Railway Station opened in April 2010, located in "East Asian Cultural Capital" -- Quanzhou City, China, is one of the main passenger stations of Fuzhou-Xiamen Railway, backed by Qingyuan Mountain, Puxian Road north and south run directly to the gate of the railway station.  Following the custom of QuanZhou local architecture, such as red walls, stone columns, stone Windows, green tiles, curved eaves, etc., the station building has a strong architectural style of southern Fujian. In order to highlight that Quanzhou is the "starting point of the Maritime Silk Road", the roof of the whole Station building is raised at both ends, like a sail. The Station connects Quanzhou with the Yangtze River Delta and the Pearl River Delta, and brings QuanZhou closer to Hong Kong, Macao, central and northern China.

This project belongs to the expansion project of QuanZhou high-speed railway station. It is adjacent to the operating high-speed railway station. There are a lot of high-speed railway trains every day, so the existing construction cannot affect the operation of high-speed railway. At the same time, the construction requirements should not exceed 11 meters in height and 1 meter in pile diameter. The foundation as backfill pond of slag, which is more complex, there are large backfill rocks, particle size range from 20 to 200 mm, single big stones with a backfilling depth ranges from 0 to 8 meters to be regarded as fragile hole formation. Most importantly, the construction should not create disturbance to the surrounding strata, lest to affect the operation of the high-speed train, in additional to having the strong ability for rock entry.  In short, the construction difficulty is great. The working height of Tyheng KR285CS is only 11 meters, the Max diameter is 2 meters, and the Max depth is 35 meters. It can solve the problems encountered in engineering construction, such as small space, large pile diameter, deep depth and high torque for rock entry. It can complete the large diameter rock entry construction despite of the low construction height and super deep construction depth.

Tyheng takes “service” as the core to focus on the Selling; Leasing; Construction; Trade-in; Re-manufacturing; Service; Operator supply & training; and consulting & promotion of drilling method. The construction team has accumulated rich experience by participating in the foreign projects (Uzbekistan etc.) and domestic projects (Zhangzhou nuclear power plant, electric transmission tower foundation, WeiYan G-serise high speed railway). The recently completed projects such as dam reinforcement; underground pipe gallery; and over-water construction have showed case the performance and reliability of Tysim small rotary drilling rigs. We believed that with TYSIM‘s reliable rigs and logistics support, Tyheng can expand the professional platform of leasing and construction all over the world.
