Comprehensive Pipe Gallery Considering Emergency Drainage and Flood Control Analysis
The precipitation in China is mainly concentrated in summer.With the frequent occurrence of"extreme weather"and"urban waterlogging"in China,waterlogging control is particularly important.How to ensure urban safety under extreme weather conditions has become a recent research hotspot.With the implementation of rainwater and sewage diversion renovation,most areas have idle rainwater facilities during non-rainy seasons,and are prone to flood disasters when rainfall exceeds the standard during rainy seasons.To improve the ability of cities to cope with excessive rainfall,the concept of dual-use and conversion between normal and emergency can be established in urban construction management.As an underground linear structure,the comprehensive pipe gallery occupies a large amount of underground space,and there is no human activity in the gallery for most of the time.During the rainy season,no one can inspect the gallery,and rainwater can quickly recover after entering the gallery,making it suitable for emergency drainage and flood prevention.The integration of pipe galleries and rainwater pipes can expand the scope of municipal infrastructure services for comprehensive pipe galleries and rainwater pipes,improve the utilization rate of comprehensive pipe galleries and rainwater pipes,and enhance the investment effectiveness of infrastructure construction.By analyzing the current research status of rainwater entering corridors,four types of drainage modes using corridor structures were proposed.The advantages,disadvantages,and applicable scenarios of each type of scenario were analyzed,providing ideas and references for the implementation of emergency drainage and flood prevention in comprehensive pipe corridors.
