Three sets of TYSIM rotary drilling rig participated in this project, including 1 set of KR300C and 2 sets of KR220C. This project is an important onshore planning node of "One Belt And One Road" in China, and also a leading project for the construction of CBD financial center.
During the construction process, the mud wall protection construction scheme was adopted in the early stage, but our personnel later found that the construction scheme could not maximize the construction benefit in this stratum according to the field hole testing for many times. The project department repeatedly studied and discussed a variety of feasible schemes, and finally adopted the water hole construction scheme provided by us based on the existing local conditions and successfully completed all the pile foundation works.
