拉萨河大型傍河水源地勘察设计及问题探讨
|
摘要
为解决某新区供水问题,需在拉萨河设置大型傍河水源地。根据区域水文地质条件及拟选定的水源地位置,开展水文地质调查、水文地质钻探、单孔、群孔抽水试验等相关测试工作,得出水源地水文地质参数;并对水源地建设的可行性进行了分析。根据获取的参数,对水源地取水方案进行平面及空间布置,对取水构筑物进行设计。在勘察、设计过程中,对取水构筑物的空间布设、设计与施工中存在的问题、水源地保护等进行了分析探讨,为拉萨河流域大型傍河水源地建设提供了一定的实践经验。
In order to solve the problem of water supply in the Lhasa New District,it is necessary to set up a large riverside groundwater field in the Lhasa River.According to the regional hydrogeological conditions and the location of the proposed water source,hydrogeological survey,hydrogeological drilling,single hole and group hole pumping tests and other related tests work were carried out,and the hydrogeological parameters of the water source were obtained.According to the obtained parameters,the scheme of the water supply was arranged in a plane and space,and the water intake structures was designed.In the process of survey and design,the spatial layout of water intake structures,the problems in design and construction,and the protection of water source areas were analyzed and discussed,which provided some practical experiences for the construction of large water source areas in the Lhasa River Basin.
