company news about Tyhen low headroom KR125ES participated in the construction of high-speed railway bridge pier overhaul project

Recently, Tyhen low headroom KR125ES stationed in Shanghai to participate in the construction of the bridge overhaul project of the Shanghai Public Works Overhaul Section and the No. 9 Line.

The project is adjacent to the operating high-speed railway line, and the height of construction equipment is required to be no more than 9 meters because of high-voltage wires and ladders under the pier. The closest place is only ten centimeters away from the ladder, so the requirements for the height of the machine construction are very strict. The on-site construction pile diameter is 800mm, and the hole depth is about 15m. The stratum is mainly composed of backfill layer, silt layer, and moderately weathered red sandstone. The strength of red yarn rock reaches 35MPa, which requires equipment with strong power and rock penetration capabilities. There is a risk of hole collapse during construction. Once the hole collapses, it will cause ground subsidence and affect the high-speed railway in operation, making construction extremely difficult. In line with professional, timely and thoughtful service, Tyhen is customer-focus, by virtue professional business quality and advanced construction technology to complete the construction tasks with high quality and efficient for customers.

In accordance with different needs of customers, Tyhen has formulated highly targeted technical solutions for construction conditions in buildings and large tunnels, bridges and high-voltage lines. KR125ES low clearance rotary drilling rig has a working height of only 8 meters, a maximum drilling depth of 20m, a maximum drilling diameter of 1.8m, and a maximum output torque of 125kN.m. Since it was put into use in the market, it has been recognized and praised by customers, so earns trust and support of our customers.

Tyhen Foundation is a rental and construction platform dedicated to small and medium-sized rotary drilling rigs established by Tysim. After five years of accumulation and investment, in cooperation with customers or independent construction, small rotary drilling rigs have been used to complete various construction applications in new fields such as costal foundation construction, embankment reinforcement, underground pipe gallery, and over water construction. Contributed to the popularization and application of engineering methods. There is reason to believe that, Tyhen,as a platform company of Tysim, will become a leading construction company and a platform-based leasing company for small and medium-sized rotary drilling rigs in China.
