company news about Multiple customized Low Headroom Rotary Drilling Rigs of Tysim Assisted in the Construction of HangZhou-WenZhou Railway

Recently, multiple KR300ES low headroom rotary drilling rigs of Tysim have been fully invested in the HangZhou-WenZhou High-speed Railway Line, and their excellent performances are unanimously praised by the site management and the general contractor.

These drilling rigs assisted in the 8th section of the HangZhou-WenZhou Hi-Spped Railway. The project is located in among TongLu County of HangZhou, PuJiang County of JinHua, and YiWu, ZheJiang. The total length of the line is 28.67 kilometers. The main projects include 1.221 kilometers of road foundations, 12 bridges including 14 continuous beams, 1 beam storage yard, 246-hole box girders, 12 tunnels, 58.286 kilometers of ballast beds, and 120.141 kilometers of new rails. The key of constructing is the complex geological conditions. In addition, the nearby railway in operation and the surrounding ground must not be disturbed. The construction height of the drilling rig shall not exceed 11 meters, and the required level of construction technology is high.

Tysim KR300ES low headroom rotary drilling rig has 4 types of pile diameters, namely 1 meter, 1.2 meters, 1.5 meters and 1.8 meters in the construction site of TongLu County and YiWu, HangZhou, and the pile depth is between 13 and 21 meters. The geological conditions are complex, mainly including miscellaneous fill (backfill stratum，large construction waste particles), silty clay, silt (with a depth ranging from 3 to 6 meters, which is easy to collapse), round gravel layer, strongly weathered silt stone, moderately weathered powder sandstone etc. The KR300ES low headroom rotary drilling rig has a construction height of 11 meters, is equipped with a 300kN.m high-torque power head, and suitable mud ratio for wall protection to solve the construction of quicksand formations. At the same time, the strong power improves the construction efficiency of rocking, which perfectly solves the problems such as small space, large pile diameter, deep depth, and difficulty in entering the rock have won unanimous praise from the on-site construction personnel and the owner of the project.

The successful R&D of fully hydraulic low headroom rotary drilling rig KR300ES has been unanimously recognized and praised by customers since it was put into the market. It has won the trust and support of customers. It is a milestone for Tysim low headroom rotary drilling rig. In the future, Tysim will continue to promote the upgrading and development of products, research and design more innovative products. This will creates greater value for customers and helps the development of the industry at the same time. We will keep the goal of being a "trustworthy expert of piling machinery and a manufacturer of excellent products ", so as to forge ahead actively!
