解决T2转运站基础水下施工的方法

Solution to underwater construction of T2 transfer station foundation

华电丰盛汕头电厂“上大压小”新建项目输煤系统T2转运站位于填海造陆形成的回填区范围,基础开挖深度深,结构形式较为复杂,地下水位深,受潮汐影响大,给基础的施工带来极大的难度。为解决该转运站涉水线以下施工难题,文章有针对性地提出解决方法,同时确保施工的安全、经济性及工期。

The T2 transfer station of the coal handling system of the new project of Huadian Fengsheng Shantou Power Plant is located in the backfill area formed by sea reclamation. The foundation excavation depth is deep, the structure is complex, the groundwater level is deep, and it is greatly affected by the tide, which brings great difficulties to the construction of the foundation. In order to solve the construction problem below the wading line of the transfer station, the paper puts forward the solution to ensure the safety,economy and time limit of the construction.
