TISCO project’s cyclone pool caisson is successfully closed

On November 20th, after five months of hard work by all the staff of the project department, the caisson project of the TISCO stainless steel medium and heavy plate project undertook by China Twenty Metallurgical Group was successfully closed.

The outer diameter of the caisson of this cyclone pool is 19.4 meters, the depth is -33.00 meters, and it is constructed by the drainage sinking method. The construction of the swirling pool faces many difficulties such as high groundwater level, narrow construction site, and a large number of built and pending structures nearby. The engineering and technical personnel of the project department carried out plan demonstration, detailed technical disclosure and refined construction, and completed the bottom sealing of the caisson on time under the premise of ensuring quality and safety. The caisson project started foundation treatment and structure production in June this year. The first sinking began on August 28, and the second sinking was launched on October 21. The back cover was successfully completed according to the total schedule node time, and the final settlement elevation and deviation Satisfy the requirements of the regulations and get high affirmation from the owner.

The application of caisson construction technology to the swirl pool has been attached great importance to by the company since the project planning stage. The project department’s engineering, technology and safety management team strictly controlled the whole process, implemented monitoring records, quality and safety control and other tasks, and finally ensured the smooth completion of the caisson project. The caisson construction method of the cyclone tank is an important part of the company’s “dual optimization” of metallurgical projects. The successful implementation of the caisson project demonstrates the superior technical advantages in the metallurgical construction field of China No. Confidence in quality completion.
