- Abstract:
- The total scale of regional water supply and intake project in the southeast of Sihong County is 15×104 m3/d. Hongze Lake is the water source, and the water intake project is constructed on a shallow lake bed. The water intake method is a combination of diversion channel and pipeline. Through the comprehensive comparison of structural form, construction convenience and economy, the water intake head was determined to be floating open caisson type, and the construction of pumping house was open caisson method. The water intake gravitational pipe construction was divided into three sections according to the crossing environmental conditions and the thickness of the soil cover, namely pipe jacking, cofferdam excavation and underwater grooving and immersed tube. The engineering practice shows that the design scheme is economical and reasonable, the key technologies and countermeasures adopted in the construction are reasonable and feasible, and the project has been running well since its completion.
