The Wuhan Scientific Research Base Project of China Electric Power Research Institute is an important investment project of China Electric Power Research Institute Co., Ltd. to implement the national strategy of State Grid Corporation of China to build a new power system. It is a major cooperation project with local governments in the development of science and technology. Wuhan Scientific Research Base is located in the East Lake National Independent Innovation Demonstration Zone in the southeast of Wuhan, north of Gaoxin Second Road, east of Tongli Road, south of Science and Technology Third Road, and west of Changshui Road. The project covers an area of about98000 ㎡, the construction area of the second bid section of the first phase is 60200 ㎡. The construction content is mainly the national key scientific research laboratory, including the cable laboratory, the transformer laboratory, the mechanical and electrical joint laboratory, and the national high voltage metrology laboratory. Including the national reference laboratory and other legal metrology zero-level laboratories awarded by the State Administration of Market Supervision.

The geology of the construction site is complex,1-10 m backfill and silt texture layer, with serious shrinkage; 10-12 rice flour sandy layer, with serious water permeability and easy hole collapse; 12-16Mee red sandstone intercalation;16-20.5 m medium weathered rock. The diameter of the bored pile on site is 600-800mm, the depth of the hole is 18m ~ 20.5m, and one hole is formed in an average of 45 minutes to 1 hour. The 8-meter casing is used to protect the wall under the puller. The TYSIM foundation is equipped with skilled operators for more than 3 years. The drilling speed and the lifting speed of the drill pipe should be strictly controlled to effectively prevent hole collapse, give full play to the advantages of large power of small drilling and successfully complete the construction.business.

  TYSIMKR125A rotary drilling rig, with a weight of 35 tons, a construction diameter range of 400~1500mm and a construction height of 15 meters, has the functions of integral pole transportation and automatic folding mast, reducing the transportation height while reducing the disassembly and assembly time during transportation. The original imported walking reducer and motor make the equipment have good climbing performance. At the same time, the 12.5-ton-meter power head torque can fully cope with most geological conditions such as pebbles and gravel. Select the original American Cummins engine with strong power, and cooperate with the electronic control system and hydraulic system of TYSIM core technology to give full play to its working ability. The whole series of products have passed GB certification and EU CE certification, and better dynamic and static stability design to ensure construction safety;
