In this embodiment, the pump pit 4 with a U-shaped cross section may be formed by forming a bowl-cup shape by processing the bottom plate 11 through a construction site or a factory mold, and then connecting the bowl-cup shape with the second port 122 of the annular side plate 12. The bowl-cup-shaped bottom plate can also be regarded as a ring-shaped structure with high strength. Figures 2 and 3, by different embodiments, both complete the connection of the pump pit 4 of U-shaped cross section.

In a specific embodiment, the lap bolts 13 of the bottom plate 11 and the side plates 12 are high-strength bolts, and the high-strength bolts can bear larger load than the common bolts, and are characterized by requiring on-site punching lap joint and being incapable of being used repeatedly, and the structure overlapped by the high-strength bolts is more stable.

Fig. 4 is a schematic side view of a pump base according to an exemplary embodiment of the present utility model, and as shown in fig. 4, the pump housing device 1 further includes a pump base 2 for supporting the pump, and the pump base 2 is connected to the bottom plate 11. The pump foundation 2 comprises a base 21 and at least one bracket 22 having a first end 221 and a second end 222, the first end 221 being connected to the base plate 11 and the second end 222 being connected to the base 21.

In this embodiment, the material of the bracket 22 and the base 21 comprises steel. The base 21 serves to support and fix the pump, and the bracket 22 supports and fixes the pump foundation 2 to the base plate 11. In practical applications, as shown in fig. 1, the height of the base 21 and the base plate 11 is a design elevation, and the design elevation is related to the length of the support 22, and the specific length of the support 22 is determined according to the process design commission.

The connection mode between the base and the bottom plate is not limited to the bracket, and can be realized by welding or bolts.

Fig. 5 is a schematic top view of a pump foundation base according to an exemplary embodiment of the present utility model, as shown in fig. 5, the base 21 is provided with a plurality of bolt holes 211 for fixing the pump, and a plurality of the bolt holes 211 penetrate through the base 21. A plurality of the bolt holes 211 are formed around a core region 212, and the second end 222 is connected to a lower side of the core region 212.

In this embodiment, the bolt holes 211 need to be uniformly and symmetrically distributed on the pump base seat 21. The number of the bolt holes 211 is determined by the specific case of the pump, wherein the number may be 2, 4, 6, 8, or the like. In practical application, as shown in fig. 5, 6 bolt holes 211 are formed in the base, and a core area 212 formed by the bolt holes 211 is used for determining the mounting position of the bracket 22, and the bracket 22 needs to be mounted in the core area 212.

In one embodiment, the base 21 is a rectangular parallelepiped with a rectangular upper surface and a rectangular lower surface. The upper and lower surfaces of the bolt hole 211 provided in the base 21 are formed with through holes.

In this embodiment, the concrete base 3 is formed by pouring low-grade waterproof concrete, and pouring concrete at the bottom of the pump pit 4 can make the pump pit 4 operate more stably and normally. Because the material of the bottom plate 11 is corrugated steel plate, the strength is high, and the interference to the foundation is small, the compression resistance requirement of the structure of the pump pit 4 can be met by using low-grade waterproof concrete. Compared with the high-grade waterproof concrete used in the traditional technology, the low-grade waterproof concrete has weaker compression resistance and tensile resistance, but has slower setting time and low price, so that more operation space is provided for constructors, and the cost can be saved.

In this embodiment, the mounting 22 is completed when the concrete is poured, further securing the pump foundation 2 and subsequently the pump mounted on the base 21. The height from the concrete base 3 to the bottom plate 11 after pouring is the pit bottom elevation, and the pit bottom elevation is the set drain 31 as a reference.

In this embodiment, the structure of the drain 31 is also poured using low grade waterproof concrete, and the drain 31 is located below the pit floor elevation. The drain 31 may be 100mm wide by 100mm deep, or 200mm wide by 150mm deep. The end of the drain 31 may be provided with a sump according to actual conditions, and the specific dimensions of the drain 31 and sump may be determined according to process design commitments in order to accomplish the required draining work of the pump housing device 1.
