文登市小观镇工业用水、人畜吃水工程是1993年由文登市水利勘测设计室勘测设计的日供水1万t、总投资1120万元的镇级供水工程。该工程水源为流域面积652km~2的黄垒河下游沙层浅层地下水,该河段河底以下沙层深达8.2m,供水工程的加压泵站位于黄垒河左岸处,由于受水泵吸程的影响,需将泵站设计成地下式,机组工作面位于地下水位线以下4.52m处。因此,泵站墙体防渗及进、出水管与墙体结合部位的防渗和机组安装,是该工程成败的关键。
The industrial water and human and animal draught engineering of Xiaoguan Town of Wendeng City was a township water supply project with a daily water supply of 10,000 tons and a total investment of 11.2 million yuan. It was surveyed and designed by the Water Resources Survey and Design Office of Wendeng City in 1993. The water source for this project is the shallow groundwater in the lower reaches of the Yellow River in the basin area of 652km2. The depth of the sand below the riverbed is 8.2m. The pressure pumping station of the water supply project is located on the left bank of the Huang River, due to the water pump. The influence of the suction process requires the design of the pumping station as underground type. The working surface of the unit is located 4.52m below the groundwater level. Therefore, impervious to the wall of the pump station and the seepage prevention and unit installation of the joints between the inlet and outlet pipes and the wall are the key to the success of the project.
