某工厂兴建一座21×50米的游泳池,浅水区水深为1.3米,深水区水深2.8米,容水量2100立方米。为缓和用水紧张,减少电耗,提高使用效益,对游泳池水进行了处理,具体做法见图1。这种做法构造、施工简易,用料方便,造价低廉。池底吸污。浇筑池底板钢筋混凝土时,沿池长方向均匀横放3根直径108毫米的钢管,预埋于混凝土内,管壁钻孔,孔径孔数经计算与水处理系统的工作泵匹配,作为池底吸污管。在管壁孔上加焊一节与孔径相当的钢管,与施工完毕的底板面平,作为池底吸污口。吸污
A factory constructed a 21×50 meter swimming pool with a water depth of 1.3 meters in shallow water and 2.8 meters in deep water with a capacity of 2,100 cubic meters. In order to ease tension in water, reduce electricity consumption, and improve the use of benefits, the swimming pool water was treated. The specific practice is shown in Figure 1. This practice is simple in construction, construction, convenient materials, and low cost. Bottom suction. When pouring reinforced concrete on the pool floor, three 108 mm diameter steel pipes are placed horizontally along the length of the pool, embedded in the concrete and drilled on the wall. The number of holes is calculated to match the working pump of the water treatment system as the bottom of the pool. Suction pipe. A section of steel pipe corresponding to the hole diameter is welded to the wall of the pipe, and it is level with the floor of the finished construction and used as the bottom suction port. Suction
