Description

Technical Field

[0001] This application relates to the field of pump station technology, specifically to a pump station. Background Technology

[0002] Pumping stations are mainly used for water transportation, discharge and management, and are widely used in urban water supply, drainage, irrigation, industrial water and other fields.

[0003] Traditional pump station structures typically employ a block-foundation structure, usually composed of a large amount of concrete to form a monolithic foundation platform. This block-foundation structure requires a significant amount of concrete, resulting in a bulky and heavy structure, which in turn places higher demands on the foundation's bearing capacity. Furthermore, the stress distribution of this structure is not clearly defined, posing challenges for refined design. These challenges manifest in several ways: Firstly, the central pier of the pump station usually has portal slots on both sides. The main load-bearing part of the central pier is the portal slot area. To ensure the structural width of the portal slots and meet overall load-bearing requirements, the thickness of the central pier can reach approximately 1.2 meters, leading to the need for… The high cost is due to several factors: First, the large volume of concrete and steel reinforcement results in higher material costs and thus a higher overall cost. Second, the large volume of concrete in the well shaft and inlet channel diversion structure releases heat of hydration during solidification, which is detrimental to the overall structural integrity of the pump station and can easily cause temperature stress due to the heat of hydration, leading to cracks in the pump station structure and affecting its durability. Third, the bottom slab of the outlet channel is relatively thick. Fourth, the pump station bottom slab is often made of a single piece of raft slab, with a thickness of about 1m to 1.2m, which is quite large, resulting in a large amount of concrete and steel reinforcement. However, the pile foundations of the bottom slab are generally evenly distributed, leading to uneven stress on the foundation.

[0004] Therefore, the structure of existing pump stations has room for further improvement. Utility Model Content

[0005] In view of this, and in response to the technical problems of bulky structure and heavy weight of existing pump stations, this application can reduce the overall amount of reinforced concrete used in the pump station by changing the structure, thereby reducing the overall weight of the pump station, improving the effective utilization rate of reinforced concrete materials, and making the stress between the various components of the pump station clearer.

[0006] To achieve the above objectives, this application provides the following technical solution: a pumping station, comprising:

[0007] The gate is used for maintenance and water retention;

[0008] Gate piers, wherein there are at least two gate piers, with adjacent gate piers spaced apart, and the gate piers are used to support the gate, and the gate piers include a central pier;

[0009] The lower foundation is connected to the gate pier and is used to support the gate pier.

[0010] The middle pier includes a gate slot column and a filling component. The gate slot column is connected to the filling component, the bottom of the gate slot column is connected to the lower foundation, and the gate is set between two adjacent gate slot columns.

[0011] The gate slot columns are made of reinforced concrete, and the filling parts are made of empty boxes or other lightweight materials.

[0012] Compared with existing technologies, this invention includes a gate, gate piers, and a foundation. The gate is used for temporary water blocking during pump unit maintenance, the gate piers support the gate, and the foundation supports the gate piers. Through the cooperation of the gate, gate piers, and foundation, a highly efficient and stable water flow control structure is formed. The pump station of this application utilizes gate slot columns and filler components. The gate slot columns support the gate, and their bottoms connect to the foundation, forming a complete support system that allows the gate to move smoothly. The gate slot columns enhance its load-bearing capacity and provide good guiding function. The filler components, made of hollow boxes or other lightweight materials, reduce the amount of concrete used without affecting structural strength, thus reducing the overall weight of the pump station. This makes the stress distribution between components clearer, providing strong protection for the safety and stability of the water conservancy project, while also reducing construction and transportation costs.

[0013] Preferably, the gate pier further includes side piers, the bottom of which is connected to the lower foundation. The side piers are located at the edge of the lower foundation, and the middle piers are spaced apart in the middle of the lower foundation.

[0014] The side of the side pier facing the gate slot column is provided with a side pier slot, which is used to install the gate.

[0015] In this embodiment, the cooperation between the side piers and the central pier ensures that the gate can be opened or closed smoothly, thereby achieving effective control of the water flow.

[0016] Preferably, the middle pier further includes a gate slot and a connecting plate, and the gate is connected to the gate slot column through the gate slot. The gate slot is used to install the gate so that the gate can be used for maintenance and water blocking.

[0017] The filling element is connected to the connecting plate on the side corresponding to the side pier. The connecting plate is located on both sides of the filling element and is made of reinforced concrete.

[0018] In this embodiment, by setting a connecting plate, the amount of concrete used can be reduced without affecting the structural strength of the pier, thus reducing the overall weight of the pump station. This makes the stress distribution between the various components clearer, providing a strong guarantee for the safety and stability of the water conservancy project, while also reducing construction and transportation costs.

[0019] Preferably, an inlet channel and an outlet channel are provided between two adjacent gate piers, and the inlet channel and the outlet channel are connected.

[0020] In the vertical direction, the water outlet channel is located above the water inlet channel;

[0021] The water inlet channel includes a well cylinder, which has a hollow cylindrical structure and is used to house the water pump.

[0022] In this embodiment, the well shaft adopts a hollow column structure, allowing the water pump to move inside the well shaft. The hollow structure helps to reduce the overall weight of the pump station, reduce the amount of reinforced concrete, reduce the adverse effects of hydration heat rise, and facilitate structural modeling and calculation.

[0023] Preferably, the top support assembly of the inlet channel serves as the bottom support assembly of the outlet channel. The bottom support assembly includes a support beam and a bottom plate. The support beam is connected to the bottom plate, and both the support beam and the bottom plate are made of reinforced concrete.

[0024] There are at least two support beams, with adjacent support beams spaced apart.

[0025] In this embodiment, by combining the support beam and the bottom plate, the overall thickness of the water outlet channel can be reduced, the amount of reinforced concrete can be reduced without affecting the strength, the utilization rate of reinforced concrete can be improved, and the cost can be saved.

[0026] Preferably, the lower foundation includes a support plate and a lower component. The support plate is connected to the lower component and is disposed between the gate pier and the lower component. The support plate is used to transfer the load of the gate pier to the lower component.

[0027] In this embodiment, the cooperation between the support plate and the lower component can effectively improve the load-bearing capacity of the lower foundation, while also preventing water penetration into the lower component and protecting the safety and durability of the lower foundation.

[0028] Preferably, the lower component includes a plurality of first and second supports, both of which are connected to a support plate, with the first supports located on both sides of the second supports.

[0029] The first pier cap is set at the bottom of the side pier, and the second pier cap is set at the bottom of the middle pier.

[0030] In this embodiment, by setting up a first pier and a second pier, the loads of the side piers and the middle pier can be effectively and evenly distributed to the first pier and the second pier, reducing local stress concentration and lowering the risk of structural stress.

[0031] Preferably, the lower component further includes a plurality of third and fourth supports, both of which are connected to the support plate, with the third supports positioned between the first and fourth supports.

[0032] Each of the third piers corresponds to a single gate pier, and the fourth pier is at least partially configured to correspond to the water inlet channel.

[0033] In this embodiment, by setting up a third and a fourth foundation, the loads of the side piers, the middle piers, and the water inlet channel can be effectively and evenly distributed to the third and fourth foundations, thereby reducing local stress concentration and lowering the stress risk of the lower foundation.

[0034] Preferably, at least one pile foundation is provided at the bottom of the first pier, at least two pile foundations are provided at the bottom of the second pier, one pile foundation is provided at the bottom of the third pier, and multiple pile foundations are provided at the bottom of the fourth pier. The pile foundations are used to bear the loads transmitted by the lower components and transfer them to the foundation.

[0035] In this embodiment, by setting pile foundations at the bottom of different piers, the bearing capacity of the entire substructure can be effectively improved, ensuring that it can safely bear the load of the superstructure. The pile foundations are not evenly distributed but can be strategically arranged. This targeted arrangement allows for the rational configuration of the number and location of piles based on the actual load distribution of the gate piers and pumping stations, ensuring that each pile foundation can effectively bear its required load.

[0036] Preferably, a filling interval is provided between the bottom plate of the water outlet channel and the lower foundation. The filling interval is located on the side of the well shaft away from the water inlet channel, and the filling interval is filled with an empty box.

[0037] In this embodiment, the filling interval is filled with an empty box, which can reduce the amount of concrete used and the overall weight of the pump station without affecting the overall structural strength of the pump station. This makes the stress between the various components clearer, providing a strong guarantee for the safety and stability of the water conservancy project, while also reducing construction and transportation costs.

Therefore, the above terms should not be construed as limitations on this application.

[0055] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 7 illustrate.

[0056] This embodiment provides a pumping station, which is applied in the field of pumping station engineering technology. Specifically, as shown in the example... Figures 1 to 7 As shown, the structure includes a pump house 1, a gate 2, gate piers 3, and a foundation 4. The gate 2 is connected to the pump house 1 and is used for maintenance and water blocking. This means that the gate 2 is used to temporarily block water when the pump unit is being maintained, ensuring that the pump unit is in a waterless state, thereby facilitating maintenance work by personnel and ensuring safe and effective maintenance. The setting of the gate 2 makes the pump unit easy to maintain, meeting the needs of water conservancy projects. There are at least two gate piers 3, with adjacent gate piers 3 spaced apart. The top of the gate pier 3 is connected to the pump house 1. The gate pier 3 is used to support the gate 2. The supporting function of the gate pier 3 ensures the smooth operation of the gate 2 during opening and closing, avoiding structural damage caused by water flow impact. The top of the lower foundation 4 is connected to the bottom of the gate pier 3. The lower foundation 4 is used to support the gate pier 3. The connection between the lower foundation 4 and the gate pier 3 provides solid support for the entire pumping station, ensuring that the gate pier 3 and the gate 2 can remain stable under various external environmental conditions. Through the cooperation of the pumping station 1, the gate 2, the gate pier 3 and the lower foundation 4, an efficient and stable maintenance water-blocking structure is formed.

[0057] The gate pier 3 includes a middle pier 32, which is located in the middle of the lower foundation 4. There are at least two middle piers 32, with adjacent middle piers 32 spaced apart. The middle pier 32 includes a gate slot column 324 and a filler 323. The gate slot column 324 has an H-shaped structure and is connected to the filler 323. The top of the gate slot column 324 is connected to the pump house 1, and the bottom of the gate slot column 324 is connected to the lower foundation 4. The gate 2 is located between two adjacent gate slot columns 324. There are at least two filler 323s, and the spacing between two adjacent filler 323s is set according to the construction design requirements. The gate slot column 324 is made of reinforced concrete, and the filler 323 is made of hollow boxes or other lightweight materials. This reduces the amount of concrete used and the overall weight of the pump station without affecting the structural strength, making the stress between the components clearer and providing a strong guarantee for the safety and stability of the water conservancy project. It also reduces the cost of construction and transportation.

[0058] Furthermore, such as Figures 1 to 3 As shown, the gate pier 3 also includes side piers 33. The top of the side piers 33 is connected to the pump house 1, and the bottom of the side piers 33 is connected to the lower foundation 4. The side piers 33 are located at the edge of the lower foundation 4, and the middle piers 32 are spaced apart in the middle of the lower foundation 4. That is, the side piers 33 are located on both sides of the middle piers 32. The side piers 33 are made of reinforced concrete to enhance the support for the gate 2. Among them, the side pier 33 has a side pier groove on the side facing the gate slot column 324. The side pier groove is used to install the gate 2. That is, when the gate 2 is located between the middle pier 32 and the side pier 33, one end of the gate 2 is connected to the side pier groove, and the other end of the gate 2 is connected to the gate slot column 324. Through the cooperation of the side piers 33 and the middle piers 32, the gate 2 can be opened or closed smoothly, thereby realizing the water blocking function.

[0059] Furthermore, such as Figure 7 As shown, the central pier 32 also includes a gate slot 321 and a connecting plate 322. The gate 2 is connected to the gate slot column 324 through the gate slot 321. The gate slot 321 is correspondingly set with the side pier slots. The gate slot 321 is used to install the gate 2 so that the gate 2 can be used for maintenance and water blocking. The side of the filling member 323 corresponding to the side pier 33 is connected to the connecting plate 322, and the side of the filling member 323 away from the gate slot column 324 is connected to the connecting plate 322. The connecting plate 322 is located on both sides of the filling member 323. The connecting plate 322 is made of reinforced concrete, which can reduce the amount of concrete used and the overall self-weight of the pump station without affecting the structural strength of the central pier 32. This makes the stress between the various components clearer, provides a strong guarantee for the safety and stability of the water conservancy project, and also reduces the cost of construction and transportation.

[0060] Furthermore, such as Figure 2As shown, gate 2 also includes maintenance gate 21 and outlet emergency gate 22. Maintenance gate 21 and outlet emergency gate 22 are arranged in parallel. Maintenance gate 21 is located upstream of the river channel and is used to regulate the flow of the river or water body to ensure that the flow of water will not affect the downstream during maintenance. Outlet emergency gate 22 is located downstream of the river channel and can be quickly closed in the event of an accident to prevent water loss and control, protect the safety of the pump unit, and block the impact of downstream water flow on the upstream unit.

[0061] Furthermore, such as Figures 2 to 4 As shown, an inlet channel 5 and an outlet channel 6 are provided between two adjacent gate piers 3. The inlet channel 5 and the outlet channel 6 are connected, which can effectively manage the inflow and outflow of water, reduce water flow resistance, and improve water flow efficiency. In the vertical direction, the outlet channel 6 is located above the inlet channel 5. The inlet channel 5 includes a well cylinder 51, which adopts a hollow column structure. The well cylinder 51 is used to house the water pump. The inside of the well cylinder 51 is hollow, and the water pump can move inside the well cylinder 51. The hollow structure can help reduce the overall weight of the pump station, reduce the amount of reinforced concrete, reduce the adverse effects of hydration heat rise, and facilitate structural modeling and calculation.

[0062] Among them, the water inlet channel 5 is provided with a flow channel guide pier on the side near the maintenance gate 21. The top of the flow channel guide pier is connected to the pump house 1, and the bottom of the flow channel guide pier corresponds to the water inlet of the water inlet channel 5. The water inlet of the water inlet channel 5 gradually narrows from the starting direction to the direction of entering the water pump, which can effectively manage the inlet and outlet of the water flow.

[0063] Furthermore, such as Figure 2 As shown, the top support assembly of the inlet channel 5 serves as the bottom support assembly 52 of the outlet channel 6. The bottom support assembly 52 includes a support beam 521 and a base plate 522. The support beam 521 is connected to the base plate 522 and is at least partially connected to the well shaft 51. Both the support beam 521 and the base plate 522 are made of reinforced concrete. There are at least two support beams 521, and two adjacent support beams 521 are spaced apart. By combining the support beams 521 and the base plate 522, the overall thickness of the outlet channel 6 can be reduced. Without affecting the strength, the amount of reinforced concrete used can be reduced, the utilization rate of reinforced concrete can be improved, and the cost can be saved.

[0064] Furthermore, such as Figure 2As shown, a filling section 7 is provided between the bottom plate 522 of the outlet channel 6 and the lower foundation 4. The filling section 7 is located on the side of the well shaft 51 away from the inlet channel 5 and below the outlet emergency gate 22. The filling section 7 is filled with an empty box, which can reduce the amount of concrete used and the overall weight of the pump station without affecting the overall structural strength of the pump station. This makes the stress between the various components clearer, provides a strong guarantee for the safety and stability of the water conservancy project, and also reduces the cost of construction and transportation.

[0065] It should be noted that other materials can also be used to fill section 7.

[0066] Furthermore, such as Figure 5 As shown, the lower foundation 4 includes a support plate 41 and a lower component 42. The support plate 41 is made of a thin waterproof membrane. The support plate 41 is connected to the lower component 42 and is located between the gate pier 3 and the lower component 42. The support plate 41 is used to transfer the load of the gate pier 3 to the lower component 42. The middle pier 32 is located in the middle of the support plate 41, and the side piers 33 are located at the edge of the support plate 41. The support plate 41 is located above the lower component 42. Through the cooperation of the support plate 41 and the lower component 42, the bearing capacity of the lower foundation 4 can be effectively improved, and the lower component 42 can be prevented from being penetrated by water, thus protecting the safety and durability of the lower foundation 4.

[0067] Furthermore, such as Figure 5 As shown, there are multiple lower components 42, and the spacing between the multiple lower components 42 is arranged according to the stress design of the construction site. The lower components 42 include multiple first piers 421 and second piers 422. The first piers 421 are rectangular structures. Both the first piers 421 and the second piers 422 are connected to the support plate 41. The first piers 421 are located on both sides of the second piers 422. The first piers 421 are set at the bottom of the side piers 33 and at both ends of the side piers 33. The second piers 422 are set at the bottom of the middle piers 32 and at both ends of the middle piers 32. The first piers 421 and the second piers 422 are set on the upstream and downstream sides of the river channel. The first piers 421 and the second piers 422 are both independent piers, which can effectively distribute the load of the side piers 33 and the middle piers 32 evenly to the first piers 421 and the second piers 422.

[0068] Furthermore, such as Figure 5As shown, the lower component 42 also includes multiple third bases 423 and fourth bases 424. The third bases 423 and fourth bases 424 are rectangular structures. Both the third bases 423 and fourth bases 424 are connected to the support plate 41. The third bases 423 are located between the first bases 421 and the fourth bases 424. Each third base 423 corresponds to a single gate pier 3. The third bases 423 are located on the side of the support plate 41 away from the gate pier 3. The fourth bases 424 are located in the middle of the support plate 41. The fourth bases 424 are at least partially corresponding to the water inlet channel 5 and at least partially corresponding to the gate pier 3. In the horizontal direction, the cross-sectional dimensions of the third pier 423 are smaller than those of the fourth pier 424. Both the third pier 423 and the fourth pier 424 are independent piers, which can effectively distribute the loads of the side pier 33, the middle pier 32 and the water inlet channel 5 evenly to the third pier 423 and the fourth pier 424, thereby reducing local stress concentration and reducing the stress risk of the lower foundation 4.

[0069] Furthermore, such as Figures 5 to 6 As shown, at least one pile foundation 43 is provided at the bottom of the first pile cap 421, at least two pile foundations 43 are provided at the bottom of the second pile cap 422, one pile foundation 43 is provided at the bottom of the third pile cap 423, and multiple pile foundations 43 are provided at the bottom of the fourth pile cap 424. The pile foundations 43 are used to bear the load transmitted by the lower component 42 and transfer it to the foundation. By setting pile foundations 43 at the bottom of different pile caps, the bearing capacity of the entire lower foundation 4 can be effectively improved, ensuring that it can safely bear the load of the superstructure. Among them, the pile foundations 43 are not evenly distributed, but can be arranged in a targeted and reasonable manner. By arranging the pile foundations 43 in a targeted manner, the number and position of piles can be reasonably configured according to the actual load distribution of the gate pier 3 and the pump house 1, ensuring that each pile foundation 43 can effectively bear its required load.

The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
