摘要
贵阳市打渔寨岩溶大泉污染系工程建设开挖破坏了原生地形地貌,在大气降水、淋漓、冲刷等综合作用下,地表迳流沿裂隙、钻孔等渗入地下补给地下水所致.保护措施:施工工程应确保桩基砼浇筑回填不得堵塞补给打渔寨水源点的岩溶管道、溶蚀裂隙等通道,防止水源断流或者水量明显减小而导致无法供水;并且有必要向有关部门申请,划定饮用水水源保护区,建立水环境质量监测和水污染排放监测站,定期进行水样检验,以确保饮用水安全.
The causes of water pollution of Da Yuzhai Karstic Spring in Guiyang City is the engineering construction excavation destroying the original landform. Protection measures are as follows： the construction project should ensure that the pile concrete pouring backfilling shall not block Da Yu- zhai water point channel,prevent water decreasing significantly or cut- off; and it is necessary to apply to the departments concerned to delineate drinking water source protection areas,establish monitoring station,test water periodically. In short,ensure the drinking water safe.
