Description
Technical Field
[0001] The utility model relates to the technical field of pipeline connection structures between a water tank and a pump house unit, and particularly relates to a pipeline connection structure for an assembled water tank and a pump house unit. Background Art
[0002] As a low-cost water-saving and water-storage device, an assembled concrete water tank (hereinafter referred to as an assembled water tank) effectively alleviates the shortage of water resources and also plays a great role in urban flood control and drainage problems, and its application is becoming more and more extensive.
[0003] At present, since the foundation slab of the pump house sinks a certain distance relative to the foundation slab of the water tank, and the pump unit is fixedly installed on the foundation slab in the pump house, in order to facilitate the construction of the pipeline connecting the pump unit in the pump house and the assembled water tank, it is often necessary to reserve a sump when pouring the foundation slab of the water tank, and several connecting pipes for connecting the pump unit and the water tank are embedded inside the foundation slab of the water tank. One end of the connecting pipe is exposed into the sump, and the other end is connected to the pump unit in the pump house through a drainage pipeline. The problems existing in the pipeline connection method between the pump unit in the pump house and the assembled water tank are as follows: since the foundation slab of the water tank is a cast-in-place and solidified forming part, settlement will occur during the solidification of the concrete slurry, so the connecting pipe is prone to position deviation in the solidified foundation slab of the water tank, resulting in inaccurate docking connection when connecting the connecting pipe and the pump unit, and it is also necessary to correct the foundation slab of the water tank again, which is time-consuming and laborious and seriously affects the construction progress; in addition, it is necessary to open holes on the side walls of the pump house and the water tank for the drainage pipeline to pass through and then connect to the pump unit. The difficulty of opening holes on the side walls of the pump house and the water tank is relatively large, and the side walls are prone to cracking during the hole opening, affecting the strength or sealing performance of the side plates of the pump house or the side walls of the water tank. For this reason, the utility model provides a pipeline connection structure for an assembled water tank and a pump house unit in order to solve the above technical problems. Summary of the Invention
