关于市政工程不同降排水方式适用性的探讨

Discussion on the Applicability of Different Dewatering and Drainage Methods in Municipal Engineering

在市政工程施工过程中经常要进行降、排水作业,所用的降、排水方式主要有集水明排、井点降水等。集水明排参数有排水沟的坡度、集水井深度等参数;井点降水涉及管井、真空井点、喷射井点等降水方式。在实际作业过程中涉及到对于降排水方式的选择,在众多方式中我们希望找到一个符合降水要求,同时又经济、满足施工工期等要求的方式。每一种降排水有其优点也有其缺点,本文通过分析不同的降排水适用条件,以期找到符合工程工况下降排水要求的最优解。

During the construction of municipal engineering,dewatering and drainage operations are often carried out.The methods of dewatering and drainage mainly include open drainage of water collection,well point dewatering,etc.Open drainage parameters of water collection include slope of drainage ditch,depth of water collection well and other parameters;Well point dewatering involves pipe well,vacuum well point,jet well point and other dewatering methods.In the actual operation process,the selection of dewatering and drainage methods is involved.Among many methods,we hope to find a way that meets the requirements of dewatering,economy and construction period.Each dewatering has its advantages and disadvantages.This paper analyzes different applicable conditions of dewatering in order to find the optimal solution that meets the requirements of dewatering.
