Description

Technical Field

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

[0002] Pumping stations are an important facility in water conservancy projects, mainly used to transport and lift water flow, realizing functions such as water resource allocation, drainage, flood control, irrigation, and water supply. They use pumps to lift water from a lower elevation to a higher elevation, or to transport water from one body of water to another, ensuring the continuity and stability of water flow.

[0003] Traditional drainage pumping stations discharge floodwater from the lower water level to the higher water level. Pump units are installed on the intake side. Considering factors such as ground elevation, flood depth, and water level, the foundation slab is set relatively low. Generally, the structural slab is set at the same height as the foundation slab, resulting in a thicker structural slab. The height difference between the thick structural slab and the outlet channel is filled with an empty box, which easily leads to material waste in the structural slab and the side piers. At the same time, it also easily leads to a large pit area for the pumping station as a whole, requiring a large amount of work in terms of pit protection and earthwork excavation, increasing construction costs and difficulty.

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

[0005] In view of this, and addressing the technical problem in the existing technology where the foundation slab is set too low and the structural slab is at the same height as the foundation slab, resulting in a large deep pit area for the pumping station and increasing the amount of earthwork excavation, this application provides a separate pumping station structure. By setting and changing the height difference between the structural slab and the foundation slab, the overall deep pit area of ​​the pumping station can be reduced, which helps to reduce the amount of engineering work in terms of pit protection and earthwork excavation. At the same time, it can also save the overall material consumption of the pumping station, save costs and reduce construction difficulty.

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

[0007] Pump chamber and opening / closing chamber are arranged along the direction of water flow;

[0008] The pump room includes a pump house, a foundation slab, and a supporting top slab located between the two; the opening and closing chamber includes an opening and closing room, a structural base slab, and a structural top slab located between the two.

[0010] The foundation slab has multiple support piles driven into the soil at its bottom, and the structural slab has multiple load-bearing piles driven into the soil at its bottom.

[0011] Compared with the prior art, the separate pump station structure of this application changes the height difference between the structural base plate and the foundation base plate, so that the structural base plate is closer to the ground level relative to the foundation base plate, thereby effectively reducing the overall deep pit area of ​​the pump room, reducing the area of ​​the deep pit area, and thus reducing the amount of foundation pit protection and earthwork excavation, which helps to save materials and reduce construction costs and difficulties.

[0012] Preferably, the pump chamber further includes an upstream gate, and the opening and closing chamber further includes a downstream gate. The upstream gate is located between the supporting top plate and the supporting top plate, and the downstream gate is located between the structural top plate and the structural bottom plate.

[0013] The upstream gate and the downstream gate are provided with multiple inlet channels and multiple outlet channels, and the inlet channels and outlet channels are connected.

[0014] In this embodiment, the upstream gate 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; the downstream gate can be quickly closed in the event of an accident to prevent the water body from getting out of control, protect the safety of the pumping station, and block the impact of the downstream water flow on the upstream unit, thereby improving the stability and safety of the overall structure of the pumping station.

[0016] One end of the pumping channel is connected to the inlet channel, and the other end is connected to the water axial flow pump.

[0017] In this embodiment, by setting up a well, the water axial flow pump can be easily installed and maintained, and it also helps to improve the stability and strength of the pumping station. The water axial flow pump is connected to the outlet channel, which allows the water pumped by the water axial flow pump to smoothly enter the outlet channel, enabling it to adapt to different water flow conditions and further improving pumping efficiency.

[0018] Preferably, the well shaft includes a supporting pier wall and a side pier wall, the supporting pier wall and the side pier wall are connected, the water axial flow pump is installed between the supporting pier wall and the side pier wall, and the water inlet channel is formed by the supporting pier wall, the side pier wall and the foundation plate;

[0019] The top of the supporting pier wall is connected to the foundation slab, the bottom of the side pier wall is connected to the foundation slab, and at least part of the side pier wall away from the supporting pier wall is connected to the structural slab.

[0020] In this embodiment, by setting up supporting piers and side piers, the structural strength of the well shaft can be enhanced, enabling it to better withstand the vibration and impact forces during the operation of the water axial flow pump.

[0021] Preferably, the end of the supporting pier facing the water inlet channel has an inner cavity, which is filled with an empty box or other lightweight material.

[0022] In this embodiment, filling the empty boxes can prevent the heat of hydration of large-volume concrete from adversely affecting the structure. At the same time, the use of empty boxes during construction can reduce the temperature of the concrete, reduce the overall weight of the pump station, reduce the amount of material used in the well shaft, and save costs.

[0023] Preferably, a cavity is provided in the middle of the side pier wall, and the cavity is filled with an empty box or other lightweight material.

[0024] In this embodiment, filling the empty boxes can prevent the heat of hydration of large-volume concrete from adversely affecting the structure.

[0028] or,

[0029] The connection end between the side pier wall and the bottom of the structural base plate is a sloping structure.

[0030] In this embodiment, the chamfer structure can be set as a rounded chamfer, a stepped chamfer, or a straight chamfer, which can effectively reduce local stress concentration and improve the overall stability and durability of the structure.

[0031] Preferably, a joint is provided between the side pier wall and the structural base plate, and multiple water-stopping components are provided at the joint, with both ends of the water-stopping components connected to the side pier wall and the structural base plate respectively.

[0032] In this embodiment, the setting of joints and the installation of water-stopping components not only enhance the waterproof performance of the structure, but also help reduce structural stress caused by factors such as temperature changes and foundation settlement, thereby improving the overall durability and safety of the pumping station.

[0033] Preferably, the well shaft is a concrete structure, with cooling pipes embedded in the well shaft wall. Temperature sensors are installed inside the cooling pipes, and the cooling pipes are connected to an external circulating water device to monitor the internal temperature of the concrete in the well shaft and regulate the cooling water flow.

[0034] In this embodiment, the temperature sensor can monitor the temperature of the water in the cooling pipe and the temperature change of the well wall concrete in real time. If the temperature is too high, the flow rate of the external circulating water device can be adjusted to increase the supply of cooling water and quickly reduce the temperature of the well wall concrete, thus ensuring the quality of the concrete and the stability of the pump station structure.

[0035] Preferably, the front opening of the inlet channel is larger than the rear opening of the inlet channel facing the outlet channel.

[0036] In this embodiment, the water flow can be gradually slowed down when entering the inlet channel, which is beneficial to the stable operation of the water pump. Attached Figure Description

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

[0049] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 3 illustrate.

[0050] Example 1

[0051] This embodiment provides a separate pump station structure, which is applied in the field of pump station technology, specifically, as follows: Figures 1 to 2 As shown, the pump room 1 and the opening / closing chamber 2 are arranged sequentially along the water flow direction. The pump room 1 includes a pump house 11, a foundation slab 12, and a supporting roof slab 13 located between the two. The opening / closing chamber 2 includes an opening / closing chamber 21, a structural base slab 22, and a structural roof slab 23 located between the two. In the vertical direction, the highest point of the supporting roof slab 13 is lower than the highest point of the structural roof slab 23, and the lowest point of the foundation slab 12 is lower than the lowest point of the structural base slab 22. The depth of the pit of the opening / closing chamber 2 is less than the depth of the pit of the pump room 1. By changing the height difference between the structural base slab 22 and the foundation slab 12, the structural base slab 22 is made closer to the ground level relative to the foundation slab 12, thereby effectively reducing the overall deep pit area of ​​the pump room 1, reducing the area of ​​the deep pit region, and thus reducing the amount of work for pit protection and earthwork excavation, which helps to save materials and reduce construction costs and difficulties. The foundation slab 12 has multiple support piles 14 driven into the soil at its bottom, and the structural slab 22 has multiple bearing piles 24 driven into the soil at its bottom. The support piles 14 and bearing piles 24 are arranged at a designed distance. The top of the support piles 14 is connected to the bottom of the foundation slab 12. The support piles 14 are used to support the foundation slab 12 and the top slab 13, and to transfer the load of the pump room 11 to the soil. The top of the bearing device is connected to the bottom of the structural slab 22. The bearing device is used to support the structural slab 22 and the top slab 23, and to transfer the load of the opening and closing chamber 2 to the soil, thereby improving the stability and durability of the overall structure of the pump station.

[0052] Furthermore, such as Figure 1 , Figure 3 As shown, pump chamber 1 also includes an upstream gate 15, and opening and closing chamber 2 also includes a downstream gate 25. The upstream gate 15 is a maintenance gate, and the downstream gate 25 is an emergency maintenance gate. The upstream gate 15 is located between the supporting top plate 13 and the supporting top plate 13, and the downstream gate 25 is located between the structural top plate 23 and the structural bottom plate 22. The upstream gate 15 and the downstream gate 25 are arranged in parallel. There are multiple water inlet channels 16 and multiple water outlet channels 26 between the upstream gate 15 and the downstream gate 25. The water inlet channels 16 and the water outlet channels 26 are connected. There are multiple upstream gates 15 and multiple downstream gates 25, and there are also multiple corresponding water inlet channels 16 and multiple water outlet channels 26. The upstream gate 15 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; the downstream gate 25 can be quickly closed in the event of an accident to prevent the water body from getting out of control, protect the safety of the pumping station, block the impact of the downstream water flow on the upstream unit, thereby improving the stability and safety of the overall structure of the pumping station.

[0053] Furthermore, such as Figures 1 to 2 As shown, multiple wells 17 are provided between the supporting top plate 13 and the foundation bottom plate 12. The wells 17 are concrete structures, and each well 17 contains a pumping channel and a water axial flow pump 171 installed within the pumping channel. The water axial flow pump 171 is connected to the outlet channel 26. One end of the pumping channel is connected to the inlet channel 16, and the other end is connected to the water axial flow pump 171. The supporting top plate 13 has mounting holes for the water axial flow pump to enter, allowing the pump to be accurately installed into the well 17. By setting up the wells 17, the water axial flow pump 171 can be easily installed and maintained, and it also helps to improve the stability and strength of the pumping station. The connection between the water axial flow pump 171 and the outlet channel 26 allows the water pumped by the water axial flow pump 171 to smoothly enter the outlet channel 26, enabling it to adapt to different water flow conditions and further improving pumping efficiency. The number and location of the well shafts 17 in this embodiment can be adjusted according to actual needs to meet different water flow and pumping requirements.

[0054] Among them, such as Figure 1 As shown, the front opening of the inlet channel 16 is larger than the rear opening of the inlet channel 16 facing the outlet channel 26. The side of the inlet channel 16 facing the well barrel 17 has an arc transition, which can reduce the local stress concentration of the inlet channel 16 structure and also allow the water flow to gradually slow down when entering the inlet channel 16, which is beneficial to the stable operation of the water pump.

[0055] Furthermore, such as Figure 1As shown, the well shaft 17 includes a support pier wall 172 and a side pier wall 173. The support pier wall 172 and the side pier wall 173 are connected. The water axial flow pump 171 is installed between the support pier wall 172 and the side pier wall 173. The water inlet channel 16 is formed by the support pier wall 172, the side pier wall 173 and the foundation plate 12. The top of the support pier wall 172 is connected to the foundation plate 12, and the bottom of the side pier wall 173 is connected to the foundation plate 12. The side of the side pier wall 173 away from the support pier wall 172 is at least partially connected to the structural base plate 22, which can enhance the structural strength of the well shaft 17 and enable it to better withstand the vibration and impact force of the water axial flow pump 171 during operation. Among them, the thickness of the end of the supporting pier wall 172 away from the supporting top plate 13 is greater than the thickness of the end closer to the supporting top plate 13. The highest point of the side pier wall 173 is slightly higher than the highest point of the structural bottom plate 22. The top of the side pier wall 173 is inclined towards the structural bottom plate 22, and its inclined surface is arc-shaped or sloping. This helps to guide the water flow smoothly into the water outlet channel 26, avoid the water flow from generating eddies or backflow in the well barrel 17, and improve pumping efficiency and construction efficiency.

[0056] Furthermore, such as Figure 1 As shown, a cavity 1731 is provided in the middle of the side pier wall 173. The cavity 1731 can extend along the height direction of the side pier wall 173. The cavity 1731 is filled with empty boxes or other lightweight materials. Filling with empty boxes can prevent the heat of hydration of large volume concrete from having an adverse effect on the structure. At the same time, the use of empty boxes during construction can reduce the temperature of the concrete, reduce the overall weight of the pump station, reduce the amount of material used in the well shaft 17, and save costs.

[0057] Among them, the connection end between the side pier wall 173 and the bottom of the structural base plate 22 is a chamfered structure. The chamfered structure can be set as a rounded chamfer, a stepped chamfer or a straight chamfer, which can effectively reduce local stress concentration and improve the overall stability and durability of the structure.

[0058] It should be noted that the connection end between the side pier wall 173 and the bottom of the structural base plate 22 can also be set as a right angle structure; or the connection end between the side pier wall 173 and the bottom of the structural base plate 22 can be a sloping structure.

[0059] Furthermore, such as Figures 1 to 2 As shown, a joint is provided between the side pier wall 173 and the structural base plate 22. Multiple water-stopping components 3 are provided at the joint. The water-stopping components 3 are copper sheet water-stops. The two ends of the water-stopping components 3 are connected to the side pier wall 173 and the structural base plate 22 respectively. The copper sheet water-stops have good elasticity and corrosion resistance, which can effectively prevent water from seeping from the joint, ensuring the sealing and stability of the pump station structure. At the same time, the setting of the joint and the installation of the water-stopping components 3 not only enhance the waterproof performance of the structure, but also help to reduce the structural stress caused by factors such as temperature changes and foundation settlement, thereby improving the overall durability and safety of the pump station.

[0060] Among them, the water inlet channel 16 of pump chamber 1 and the water outlet channel 26 of opening and closing chamber 2 are both treated with joint treatment. When filling the joint, asphalt paste is injected or applied into the joint to form an elastic and waterproof sealing layer, which can prevent moisture, impurities, air and other substances from entering the joint.

[0061] Furthermore, cooling pipes are pre-embedded in the wall of shaft 17. These pipes have a spiral structure and are equipped with fiber optic temperature sensors. The cooling pipes are connected to an external circulating water system to monitor the internal temperature of the concrete in shaft 17 and regulate the cooling water flow. This ensures effective temperature control during concrete pouring, preventing problems such as concrete cracking due to excessive temperature. The temperature sensors monitor the water temperature within the cooling pipes and the temperature changes of the concrete wall in shaft 17 in real time. If the temperature becomes too high, the flow rate of the external circulating water system is adjusted to increase the cooling water supply, rapidly reducing the temperature of the concrete wall and ensuring the quality of the concrete and the stability of the pump station structure. The concrete in shaft 17 is poured in layers, with cooling pipes embedded in each layer and water flowing through them for cooling. The water flow rate is dynamically adjusted based on sensor data. The internal support structure of the pump station is 3D printed using biodegradable materials, which automatically dissolve after pouring, avoiding the losses associated with traditional formwork removal.

[0062] Furthermore, a flap gate 27 is provided between the downstream gate 25 and the shaft 17. The flap gate 27 is connected to the flap gate 27 support pier. The flap gate 27 serves to cut off the flow to prevent the water flow from the outlet 26 from flowing back into the water axial flow pump 171 and causing the water axial flow pump 171 to reverse.

[0063] Example 2

[0064] The difference between this embodiment and Embodiment 1 is that, in this embodiment, as... Figure 3 As shown, the supporting pier wall 172 has an inner cavity 1721 at one end facing the water inlet channel 16. The inner cavity 1721 can be located in the thick wall of the supporting pier wall 172 and can extend along the height direction of the supporting pier wall 172. The inner cavity 1721 is filled with empty boxes or other lightweight materials. Filling with empty boxes can prevent the heat of hydration of large volume concrete from having an adverse effect on the structure. At the same time, the use of empty boxes during construction can reduce the temperature of the concrete, reduce the overall weight of the pump station, reduce the amount of material used in the well shaft 17, and save costs.
