Detailed Description

In order to make the technical solutions in the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall belong to the protection scope of the present invention.

In the following, river channels in areas where Liuxinzhuang and Zhi zhuang in Xiujin county of Shandong province are located are taken as examples.

In low-lying areas of the land, self drainage is difficult, and after water delivery projects of seven-river and six-river and five-river in the first period of north-south water transfer are implemented, a management road is newly built on one side of the six-river and five-river, and a pumping station for irrigation and drainage is dismantled, so that waterlogging in the areas is more difficult to drain.

According to the drainage requirements, 1 drainage pumping station is newly built at the place where the nine ditches enter the six-five river and the joint of the rear road-collecting ditch and the six-five river, has the same structural style and consists of an upstream connecting section, a front pond 3, main and auxiliary plant buildings of the station body, a water outlet pond 4, a self-drainage culvert 2, a drainage lock chamber, a steep slope, a stilling basin, a sea wall and the like.

The upstream connecting section of the drainage station is smoothly connected with the current drainage ditch.

The drainage pumping station adopts a 1000ZLB-3(-2 DEG) type vertical axial-flow pump, the single machine flow is 2.51m3/s, and the design lift is 3.20 m. The nine pumps are installed in 2 stations without using machine sets; and 2 machine sets of the rear-lower pump station are installed without equipment.

The upstream connecting section of the drainage pumping station adopts an M10 grout block stone twisted surface 8 structure, and the forebay 3 adopts a U-shaped groove structure. The bottom plate and the side walls of the underground part of the main workshop are of a C30 reinforced concrete structure. The upper part of the main workshop is of a reinforced concrete frame structure. The water outlet pool 4 is of a C30 reinforced concrete structure, and has a impermeability grade W6 and an antifreeze grade F150.

Aiming at small-sized drainage pumping stations, a self-drainage culvert 2 is additionally arranged in an original main plant, is arranged between two water pumps 1 and is integrally poured with the pumping stations, and a plane cast iron gate and a single-lifting-point manual screw rod type hoist are arranged.

The working process is as follows: when the side water level of the waterlogging area is higher than the water level of the river channel, the gate of the culvert is opened, water flows through the two sides of the middle pier and enters the self-draining culvert 2, and waterlogging water is drained automatically by utilizing the difference of upstream and downstream water heads; when the side water level of the waterlogging area is lower than the water level of the river channel, the gate is closed, and the unit is opened to lift and drain the waterlogging.

The drainage pumping station has the following functions: when the water level in the drainage ditch is higher than the water level in the sixty-five rivers, the gate of the culvert is opened, and the waterlogging water is drained automatically by utilizing the difference between the upstream water head and the downstream water head; when the water level in the sixty-five rivers is higher than that in the drainage ditch, the gate is closed, and the unit is opened to lift and drain the waterlogging.

The utility model provides a pump station for relief low-lying region adds self-draining culvert 2 in the main factory building, when waterlogging area side water level is higher than the river course water level, opens the gate of culvert, and rivers are through middle mound both sides, get into self-draining culvert 2, utilize the difference of upstream water head self-draining waterlogging; when the side water level of the waterlogging area is lower than the water level of the river channel, the gate is closed, and the water pump 1 is started to lift and drain the waterlogging. This type fuses the waterlogging and arranges and draw water and arrange the waterlogging in an organic whole, according to actual conditions, the operation mode is flexible, can effectively save the operation administrative cost.
