[0024] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below in conjunction with specific embodiments.
[0025] Combination Figure 1 to Figure 2As shown, this embodiment is a layout structure of a riverside water intake pump station, which is mainly used in large-scale riverside water intake pump stations. A layout structure of a riverside water intake pump station includes a water intake head foundation pit 9, a water intake head 1, a pump house foundation pit 10, a main pump house 6 and a water diversion steel pipe. The water intake head foundation pit 9 is set at a suitable position in the river, and the water intake head 1 is set in the water intake head foundation pit 9. The water intake head 1 draws water from the river through the water inlet hole. The position of the water intake head foundation pit 9 can be flexibly arranged to ensure that the water intake head 1 can obtain high-quality water from a suitable position in the river. The pump house foundation pit 10 is set on the river bank side, and the position of the pump house foundation pit 10 is a certain distance away from the river bank. The pump house foundation pit 10 is lower than the original ground line 12, and a main pump house 6 is arranged in the pump house foundation pit 10. At the same time, the position of the pump house foundation pit 10 needs to consider avoiding the impact of the river water level fluctuation on the main pump house 6 as much as possible. The first end of the water diversion steel pipe is connected to the water intake head 1, and the second end of the water diversion steel pipe is connected to the water inlet end of the main pump room 6. The water outlet end of the main pump room 6 is connected to the water outlet structure.
[0026] Compared with the solution of arranging the water intake structure and the main structure of the pump house together as an integral whole, the present application arranges the water intake structure separately from the main structure of the pump house. On the one hand, the water intake structure can obtain high-quality water at a suitable position in the river. On the other hand, the main structure of the pump house is far away from the river bank, reducing the impact of the river water level fluctuation on the main structure of the pump house, thereby eliminating the need to build a higher pump house building and reducing project investment.
[0027] In some embodiments, the water outlet structure includes a water outlet tunnel 7, a water outlet tower foundation pit 11 and a water outlet tower 8. The water outlet tower 8 is installed in the water outlet tower foundation pit 11. One end of the water outlet tunnel 7 is connected to the water outlet end of the main pump room 6, and the other end of the water outlet tunnel 7 is connected to the water outlet tower 8.
[0028] In some embodiments, the water diversion steel pipe includes a submerged pipe 2 and a jacking pipe 3, and the water outlet of the water intake head 1 is connected to the water inlet of the main pump room 6 through the submerged pipe 2 and the jacking pipe 3 in sequence. A maintenance valve well 4 is provided in the middle of the jacking pipe 3, and the maintenance valve well 4 can also serve as a working well and a receiving well of the jacking pipe 3 during construction. A water inlet well 5 is provided between the jacking pipe 3 and the water inlet of the main pump room 6. The water inlet well 5 can serve as a forebay of the water pump suction pipe of the main pump room 6, so that the river water sediment flowing into the water body through the jacking pipe 3 can be fully precipitated, thereby reducing the abrasive damage of the sediment to the water pump unit in the main pump room 6.
[0029] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
