井点降水技术在市政道路工程中的应用

Application of Well-point Dewatering Technology in Municipal Road Engineering

摘要:

我国东南沿海地区由于其独特的区位优势，成为发展各类产业园的首选地区，但其地下水位普遍较高、土质松软，为工程建设带来了一定困难。通过项目实践，介绍了井点降水在市政道路施工中的运用,并提供了理论公式与有限元计算的分析，表明了井点降水技术适用于有一定透水性的土体，该工法在路基施工、地下管线施工时起到了提升土体工程特性，保证管线顺利开挖施工的作用，具有良好的可行性和经济性。

Abstract:

The southeast coastal area of China has become the first choice for the development of various industrial parks due to its unique geographical advantages. But its high groundwater level and soft soil bring some difficulties to the engineering construction. Through a project practice, the application of well-point dewatering technology in the municipal road construction is introduced. And the theoretical formula and finite element analysis are provided. It is shown that the well-point dewatering technology is suitable for a certain permeability of the soil. The method in subgrade construction and underground pipeline construction plays the roles of improving the soil engineering characteristics and ensuring the pipeline excavation construction smoothly. The method has good feasibility and economy.
