摘要
Abstract
The feasibility of long-distance deep-buried sewage pipeline inverted rainbow crossing river technology was systematically evaluated.Based on long-term hydrological data,the evolution law of the river channel was ana-lyzed.And the maximum scouring depth was determined through general scour and local scour schemes;An innova-tive engineering scheme sewage pipelines crossing rivers is proposed under conditions suitable for long-distance and deep-buried.The results show that:1)Long-term hydrological data can effectively simulate the evolution law of river channel and provide a scientific basis for determining the maximum scouring depth of the river;2)The installation method of combination of multi-fold inverted siphon structure with the"large pipe encasing small pipe"ensures sta-ble construction and operation of the pipeline;3)The combined construction methodology of"segmented working shafts+slurry balance pipe jacking+and auxiliary relay chambers,"supported by dewatering and layered excavation shoring techniques guarantees the safe crossing of the pipelines.The research provides strong technical support for the construction of long-distance deep-buried sewage pipelines crossing rivers under complex topographic conditions.关键词
