在进行水利管道施工中,会经常遇到地下水的水位相对较高的情况,遇到这种情况往往就需要先进行降水,而在管道施工中最为常见的降水法就是筒井降水法。在许多地方的排水管道施工中,会有许多以前的管道埋得太深的情况,如果遇上地下水位偏高或者遇到粉细砂地层,管道施工时很难进行的。因此,筒井降水法主要解决的就是这些难题,不仅能改善工人们的施工条件,还能保证工程施工的质量,提高施工的可操作性,同时加快工程施工进度,节约工程施工的开支。本文将从筒井降水法的使用范围和优点、筒井降水法的应用分析、施工中应该注意的问题等几个方面来论述筒井降水法在管道施工中的应用。
In the construction of water conservancy pipelines, water level of groundwater will be often encountered relatively high situation, in which case often need to carry out precipitation, and the most common in the pipeline construction of the precipitation method is the tube well precipitation method. In many areas of the drainage pipeline construction, there will be many previous pipeline buried too deep case, in case of high water table or meet the fine sand formation, the pipeline construction is very difficult. Therefore, the main solution to these problems is not only to improve the working conditions of workers, but also to ensure the quality of construction and improve the operability of construction, at the same time to speed up the construction progress and save the construction expenditure. This article will discuss the application of tube well dewatering method in pipeline construction from several aspects such as the scope and advantages of tube well dewatering method, application analysis of tube dewatering method, and problems that should be noticed in construction.
