提高行车舒适性的山地城市排水检查井

Improvement of Drainage Manhole in Mountainous Cities for Driving Comfort

摘要:

排水检查井作为市政基础设施的重要组成部分，其井盖的位置直接影响着道路整体性、结构稳定性、检修安全性与行车舒适性。针对管道中心位于路缘石下及距路缘石0.5 m的车行道下的检查井这两种工况进行分析，优化检查井井室尺寸，提出了在管道布置条件受限的条件下，排水管道位于道路断面不同位置处时，排水检查井该如何进行不同的工艺设计以避免使井盖位于车行道，从而提高行车舒适性和检修安全性。研究成果可为类似工程设计提供参考。

Abstract:

As an important part of municipal infrastructure, the location of drainage manhole cover will directly affect the road integrity, structural stability, maintenance safety and driving comfort. The two working conditions of the manhole with the pipeline center located under the curb and under the roadway 0.5 m away from the curb are analyzed. The chamber size of the manhole is optimized. It is proposed that how to carry out the different technological designs of drainage manhole to avoid the location of manhole on roadway under the conditions of limited pipeline layout and when the drainage pipelines are located at the different positions of road section, which can improve the driving comfort and maintenance safety. The research results can provide the reference for the design of the similar projects.
