Recently, multiple Tysim KR125A rotary drilling rigs have been deployed simultaneously on the Wuhan Caidian Zhashan Street Industrial Park public service facility supporting construction project, setting a record of 400 meters drilled in 10 hours by a single rig and completing over 3,000 piles within one month, creating conditions for the project to finish foundation construction in a short period and be completed early.

Construction site

The Phase II project of the Wuhan Caidian Zhashan Street Industrial Park public service facility supporting construction is a key project of Caidian District for 2022 and a major livelihood project. The project covers a land area of 128,784 m² with a building area of 435,851 m². The main construction content includes: 1 mid-rise building and 22 high-rise residential buildings, totaling 2,733 housing units, along with 2 kindergartens, 1 community work service room, 2 cultural activity stations, 2 elderly care service buildings (non-elderly care facilities), 1 small commercial facility, supporting commercial and financial services, 2 fire control rooms, 1 switching station, 7 power distribution rooms, 1 domestic waste collection station, 1 public toilet, 1 community health service station, 2 property management rooms, and 2 gatehouses. Supporting infrastructure includes site works, roads, landscaping, greening, power supply and distribution, water supply and drainage, fire protection, gas supply, ventilation, and network systems.

The geological conditions at the site mainly consist of backfill soil, clay, strongly weathered and moderately weathered limestone. The piles are approximately 15 m deep with a diameter of 600 mm. The complex strata make construction difficult and impose high requirements on rig stability and reliability. Tysim KR125A compact rotary drilling rigs, together with professional operators and construction method experts from its wholly-owned subsidiary Taiheng Foundation, worked against the clock to seize the schedule and went all out to advance progress for the early completion of the project, completing the pile foundation construction with high quality, high efficiency, and high safety, earning unanimous praise from the project department.
