- Abstract:
- According to local conditions, a pipe crossing river technology combined with pipe jacking and pipe sinking is selected for trunk main of Shaoguan No. 3 wastewater treatment plant to cross Beijiang River section by comprehensively comparing and analyzing the key influencing factors such as scheme applicability, constructability and risk, shipping, flood control, environmental protection, scenery, operation safety and cost. Pipe jacking and pipe sinking technologies are adopted in the section to cross the levee and the river, and steel cofferdam well is innovatively proposed to solve the pipe connection problem between pipe jacking and pipe sinking, which can reduce the construction risk and ensure the safe implementation of the project. The technical key points of levee reinforcement, anti-seepage and connection of jacking and sinking in the implementation process of pipe jacking, pipe sinking and the combination of pipe jacking and pipe sinking were summarized, and the comprehensive solutions were proposed. The design not only meets the functional needs of sewage entering into the plant, but also protects the levee structure and the shipping safety in Beijiang River, which provides engineering design experience for sewage pipeline crossing great rivers.
