DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 8 As shown, the utility model provides a split prefabricated pump station, including a pump station body. It should be noted that the utility model does not involve improvements to pump station accessories such as pumps, control boxes, and pipelines. The aforementioned accessories are all conventional components and should be selected and installed according to actual design requirements, so the description of these accessories is omitted.

[0028] The pump station body comprises a concrete base 3, a concrete link 1 and a concrete top cover 2 fixed up and down by a connecting piece 10. The concrete base 3, the concrete link 1 and the concrete top cover 2 are all prefabricated concrete parts.

[0029] The bottom of the concrete base 3 is provided with a flange structure for fixing on a base in the foundation pit by anchor bolts. The height of the concrete base 3 is set to 20-30 cm.

[0030] like Figure 5As shown, three concrete segments 1 are provided. As a preferred example, the concrete segment 1 includes a concrete ring body 101 and a steel cage 102 pre-buried inside the concrete ring body 101. The purpose of providing the steel cage 102 is to increase the strength, thereby reducing the wall thickness of the concrete segment 1, thereby reducing the cost and weight. The diameter of the concrete segment 1 is 2-4m, the height is 1.5-2m, and the wall thickness is 5-10cm. The specific number of concrete segments 1 is determined according to the design requirements of the pump station body. The concrete segment 1 located at the bottom layer is pre-buried with an inlet pipe 9, and the concrete segment 1 located at the top layer is pre-buried with an outlet pipe 7. The inlet pipe 9 and the outlet pipe 7 are used to connect the internal pipelines of the pump station.

[0031] like Figure 7 As shown, since the concrete top cover 2 has the lowest bearing force requirement, in order to reduce the amount of concrete, as a preferred example, the concrete top cover 2 includes a concrete cover body 201 and a metal cover body 202 embedded in the center of the concrete cover body 201. That is, an opening is provided in the center of the concrete cover body 201, and the diameter of the opening is 4 / 5-9 / 10 of the diameter of the concrete cover body 201. The metal cover body 202 is fixed at the opening in a pre-embedded manner. The outer edge of the metal cover body 202 is provided with a bent boss structure to improve the bonding force of the pre-embedded connection. The connection between the two is waterproof and sealed, for example, by coating with waterproof paint. The metal cover body 202 is provided with a manhole 203 and a vent 204. A manhole cover 5 is installed at the manhole 203. A handrail 6 is installed on one side of the manhole 203 to cooperate with the ladder 12 in the pump station to realize the entry and exit of personnel. A ventilation pipe 4 is installed at the vent 204.

[0032] The ends of the concrete base 3, the concrete link 1 and the concrete top cover 2 are all provided with a tongue-and-groove structure, which is used for axial positioning, and a sealing layer 8 is provided on the outside of the tongue-and-groove structure for waterproofing. The inner walls of the three main components are pre-buried with connecting seats 15 evenly distributed around the circumference, and each prefabricated component is fixed with three connecting seats 15, and the upper and lower layers of connecting seats 15 are staggered and connected one by one through the connecting piece 10. In other words, the connecting piece 10 and the connecting seat 15 are connected at an angle to form a triangular structure, which can form a stable connection in both the circumferential direction and the axial direction.

[0033] As a preferred example, Figure 4As shown, the connection seat 15 is an H-shaped steel, that is, the H-shaped steel is cut according to the size and processed, and holes are punched on its wing plate and web, and then pre-embedded and cast. The upper and lower wing plates of the connection seat 15 are fixedly connected to one end of the angle seat 14, and the other end of the angle seat 14 is hingedly connected to the end of the connector 10, and the connection method is bolt connection. Specifically, the angle seat 14 has a first connection part and a second connection part. The first connection part is bent, and its horizontal part is connected to the wing plate, and its bent part is connected to the second connection part. The center line of the connection hole on the second connection part is perpendicular to the center line of the connection hole on the first connection part. The second connection part is connected to the connector 10. Through this structure, the connector 10 and the connection seat 15 can be connected at any angle.

[0034] Since the height and diameter of the concrete link 1 are determined according to the design requirements, multiple specifications can be designed to meet the construction requirements of different pipe network systems. Therefore, in order to adapt to the installation of concrete prefabricated parts of different specifications, as a preferred example, the connector 10 is a basket screw. The basket screw can adjust the overall length as required and has good flexibility and adaptability. It should be noted that the use load of the connector 10 should be above 1 t.

[0035] In order to reduce cost and weight, the wall thickness of the concrete segment 1 is lightweight, that is, the wall thickness is reduced, so the length of the connection seat 15 embedded in the concrete ring body 101 is limited. Therefore, in order to improve the firmness of the connection seat 15, all the connection seats 15 of each layer are reinforced by arc-shaped top hoops 13. Specifically, the webs of two adjacent connection seats 15 on the inner wall of the concrete segment 1 are fixedly connected with the arc-shaped top hoops 13, and the connection method is bolt connection.

[0036] like Figure 6 As shown, as a preferred example, the arc-shaped top hoop 13 includes an arc-shaped hoop plate 1301 whose two ends are bent inward to form a connection portion 1303 and an arc-shaped rib plate 1302 vertically arranged inside the arc-shaped hoop plate 1301 and connected to the connection portion 1303. The outer diameter of the arc-shaped hoop plate 1301 matches the inner diameter of the concrete segment 1, so that the outer wall of the arc-shaped hoop plate 1301 is closely attached to the inner wall of the concrete segment 1 to form a support, so that the arc-shaped top hoop 13 is firmly fixed in the concrete segment 1, and at the same time, it also supports the connection seats 15 on both sides to prevent them from being separated from the concrete segment 1.

[0037] It should be noted that another function of the arc-shaped top hoop 13 is to provide an installation basis for other components in the pump station, such as the maintenance platform 11, which can be fixedly installed on the arc-shaped rib plate 1302 of a certain layer of the arc-shaped top hoop 13.

[0038] As a preferred example, the sealing layer 8 is formed by coating glass fiber cloth and adhesive and then curing, and all metal parts are also treated with rust and corrosion prevention.

[0039] Compared with the integrated prefabricated pump station, the split prefabricated pump station in the utility model has lower cost, is easy to manufacture and install, and the prefabricated concrete parts can be easily punched and modified later. In addition, it does not need to be customized by the manufacturer but can be manufactured by the construction party, which has good flexibility and adaptability.

[0040] The matters not described in detail in the present invention are all known technologies to those skilled in the art.

[0041] It should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
