Description

Technical Field

[0001] The present invention belongs to the relevant field of prefabricated pump station technology, and more specifically relates to an anti-floating device for an integrated prefabricated pump station. Background Art

[0002] The integrated prefabricated pump station is a prefabricated pump station equipment that integrates multiple functions. It is mainly used to lift and transport sewage, rainwater, drinking water or wastewater, etc. It is uniformly produced and assembled by the factory and then transported to the site for installation. It has the characteristics of high efficiency, convenience and environmental protection.

[0003] The patent application recorded in publication number CN115404949A discloses an integrated prefabricated pump station, including a shell, one side of which is fixedly connected to a water inlet pipe, the other side of which is provided with a water outlet, the top of the shell is fixedly connected to a lifting motor, one side of the lifting motor is provided with an entry port, and the middle part of the inner cavity of the shell is fixedly connected to a baffle. The present invention provides a lifting mechanism to ensure that construction workers can easily enter the pump station without climbing stairs when entering the pump station, thereby ensuring the personal safety of the construction workers. Even if the construction workers carry more construction equipment, they can easily enter the interior, thereby improving work efficiency. The fixed motor and the card block are provided to fix the support plate, thereby preventing the support plate from sliding downward when it stops in the middle, and having a good fixing effect on the support plate.

[0004] The above-mentioned integrated pump station has certain deficiencies during installation and use. In order to prevent groundwater from generating buoyancy on the cylinder structure of the integrated pump station, the pump station base generally adopts a U-shaped chassis with grouting holes on the side, and uses concrete grouting to prevent floating. However, when encountering an area with abundant groundwater or the diameter of the pump station is too large and the concrete grouting cannot be in place, after the pump station is installed and backfilled, the groundwater will form pressure on the bottom of the pump station, causing the bottom to rise and damage the internal pipeline structure until the pump station is scrapped; secondly, the traditional integrated pump station has a single anti-floating structure and does not have multiple anti-floating structures. When there is a lot of groundwater, its buoyancy exceeds the anti-floating upper limit of the device, reducing the anti-floating effect of the integrated pump station; at the same time, the integrated pump station is installed with an underground structure, so that the bottom of the integrated pump station is in full contact with the soil, which makes the bottom of the integrated pump station prone to rust, and the groundwater is mixed with a large amount of mud and sand, which blocks the traditional anti-floating structure pipeline and affects its stability. Summary of the invention

[0005] The purpose of the present invention is to provide an anti-floating device for an integrated prefabricated pump station, which can solve the existing problems.

[0006] The problem to be solved by the present invention is:

[0007] 1. To prevent groundwater from generating buoyancy on the cylinder structure of the integrated pump station, the pump station base generally adopts a U-shaped chassis with grouting holes on the side to prevent buoyancy. However, in areas with abundant groundwater or when the pump station diameter is too large and concrete grouting cannot be in place, after the pump station is installed and backfilled, groundwater will form pressure on the bottom of the pump station, causing the bottom to rise and damage the internal pipeline structure until the pump station is scrapped;

[0008] 2. Secondly, the anti-floating structure of the traditional integrated pump station is single, and it does not have multiple anti-floating structures. When there is a lot of groundwater, its buoyancy exceeds the anti-floating upper limit of the device, reducing the anti-floating effect of the integrated pump station;

[0009] 3. At the same time, the integrated pump station is installed in an underground structure, so that the bottom of the integrated pump station is in full contact with the soil, which makes the bottom of the integrated pump station prone to rust. In addition, the groundwater is mixed with a large amount of mud and sand, which blocks the traditional anti-floating structure pipeline and affects its stability.

[0010] The purpose of the present invention can be achieved through the following technical solutions:

[0011] An anti-floating device for an integrated prefabricated pump station comprises a fixed chassis and an anti-floating device, wherein the anti-floating device is fixedly mounted on the upper outer surface of the fixed chassis, a connecting hole for cooperating with the anti-floating device is provided at the bottom of the fixed chassis, an annular water tank is fixedly mounted on the outer surface of the fixed chassis, a reinforcing piece is fixedly mounted on the bottom outer surface of the annular water tank; the anti-floating device comprises a short-circuit flange, a first connecting pipe and a second connecting pipe, the first connecting pipe is fixedly mounted on the outer surface of one side of the short-circuit flange, the second connecting pipe is fixedly mounted on the outer surface of the other side of the short-circuit flange, a check valve is provided at the end of the first connecting pipe, an electrically controlled valve is fixedly mounted at the end of the second connecting pipe, and the annular water tank and the second connecting pipe are connected through a drainage pipe.

[0012] As a further technical solution of the present invention, the connecting hole is connected to the lower end of the short-circuit flange, and the outer side of the fixed chassis is filled with concrete. The cross-section of the fixed chassis is a U-shaped structure. When groundwater forms pressure on the bottom of the pump station, a connecting hole connected to the short-circuit flange is drilled at the bottom of the pump station. The groundwater flows into the fixed chassis of the pump station cylinder through the connecting hole, thereby eliminating the bottom pressure, protecting the safety of the equipment in the pump station, and relieving the pressure on the bottom of the pump station cylinder. The electric control valve can control the opening and closing of the second connecting pipe, so that the water body is transported to the fixed chassis or the inside of the annular water tank. When there is more groundwater, the second connecting pipe can be opened to transport the water body to the inside of the annular water tank.

[0013] As a further technical solution of the present invention, the upper part of the annular water tank and the fixed chassis are butt-jointed and fixed by an upper fixing ring, and the lower part of the annular water tank and the fixed chassis are butt-jointed and fixed by a lower fixing ring. The annular water tank can not only perform temporary water storage operations, but also increase the weight of the fixed chassis and enhance the anti-floating effect of the fixed chassis. The annular water tank is fixed to the outside of the fixed chassis by using the upper fixing ring and the lower fixing ring. When the annular water tank is full of water, the annular water tank applies its own weight to the fixed chassis, thereby increasing the weight of the fixed chassis and enhancing the anti-floating effect of the fixed chassis.

[0014] As a further technical solution of the present invention, an exhaust pipe is fixedly installed on the outer surface of the upper end of the annular water tank, an annular notch is provided inside the annular water tank, and a fixed cover plate is fixedly installed on the upper end of the short-circuit flange. Since the prefabricated pump station is installed underground, the annular water tank and the fixed chassis are both buried underground. The exhaust pipe is provided to exhaust the interior of the annular water tank during the water storage operation. At the same time, the pouring of concrete can increase the weight of the fixed chassis and enhance the anti-floating effect of the fixed chassis.

[0015] As a further technical solution of the present invention, the reinforcement member includes a breaking cone, a fixed plug rod and a connecting rod. The breaking cone is fixedly installed on the outer surface of one end of the fixed plug rod, and the connecting rod is movably installed on the outer surface of the other end of the fixed plug rod. When the annular water tank is installed underground, the reinforcement member can improve the stability of the annular water tank and play a reinforcing role between the annular water tank and the soil.

[0016] As a further technical solution of the present invention, side-rotating cones are movably installed on both sides of the ground-breaking cone and the fixed insertion rod. The ground-breaking cone and the side-rotating cone, as well as the fixed insertion rod and the side-rotating cone are all connected by elastic hinges. When the fixed insertion rod and the side-rotating cone are inserted into the soil, the elastic hinge is used to release the side-rotating cone, so that the side-rotating cone is stuck into the soil, so that the reinforcement piece and the soil are firmly connected, and the side-rotating cone plays an auxiliary reinforcement role.

[0017] As a further technical solution of the present invention, the fixed insertion rod and the connecting rod are movably connected by a threaded rod, and the upper end of the connecting rod is spliced ​​and installed with a rotating wheel for use with the threaded rod. When the reinforcement piece is docked with the soil, the breaking cone at the lower end of the reinforcement piece is first inserted into the soil, so that the entire reinforcement piece is placed in the soil during the downward pressing process. At this time, the side edge of the side-rotating cone is in contact with the soil, and the side-rotating cone is opened outwardly in cooperation with the elastic hinge when the breaking cone and the fixed insertion rod move upward, and the threaded rod is rotated by the rotating wheel, so that the threaded rod can drive the breaking cone and the fixed insertion rod to move upward, while keeping the connecting rod in position unchanged, so that the side-rotating cone is opened outward and inserted into the inner side of the soil, and then the connecting rod is connected to the bottom of the annular water tank to complete the reinforcement operation of the annular water tank.

[0018] As a further technical solution of the present invention, a drainage board is provided at the bottom of the fixed chassis, and a filter plate is provided at the bottom of the drainage board. The interior of the drainage board is a hollow structure, and the drainage board adopts a full-coverage structure design, so that the drainage board covers the bottom of the fixed chassis as a whole, and drainage operations can be performed at any position on the bottom of the fixed chassis. At the same time, because the groundwater contains a large amount of sediment, in order to avoid blockage of the pipeline, the sediment can be filtered by adding a filter plate.

[0019] As a further technical solution of the present invention, a first water tank is fixedly installed on one side of the drain board, and a second water tank is fixedly installed on the other side of the drain board. The first water tank and the second water tank are symmetrically arranged, and the water collected by the drain board can be stored by the first water tank and the second water tank.

[0020] As a further technical solution of the present invention, a sealing ring is fixedly installed on the outer surface of the upper end of the drain plate, and the drain plate and the first water tank as well as the drain plate and the second water tank are connected through a connecting pipe.

[0021] Beneficial effects of the present invention:

[0022] 1. By setting up an anti-floating device, when the anti-floating device for the integrated prefabricated pump station is used, the bottom thereof has a drainage anti-floating structure to prevent the prefabricated pump station from floating up, and groundwater can be introduced into the interior of the pump station, thereby eliminating the bottom pressure of the pump station and improving its stability;

[0023] During operation, when groundwater forms pressure on the bottom of the pump station, a connecting hole connected to the short-circuit flange is drilled at the bottom of the pump station, and the groundwater flows into the fixed chassis of the pump station cylinder through the connecting hole, thereby eliminating the bottom pressure, protecting the safety of the equipment in the pump station, and relieving the pressure on the bottom of the pump station cylinder. The electric control valve can control the opening and closing of the second connecting pipe, so that the water is transported to the fixed chassis or the inside of the annular water tank. When there is more groundwater, the second connecting pipe can be opened to transport the water to the inside of the annular water tank. In order to prevent the water in the pump station cylinder from flowing back to the outside of the cylinder, the upper end of the short-circuit flange is The end fixed cover is sealed, and a check valve is installed in the side with a tee. When the bottom of the pump station is under pressure, groundwater enters the short-circuit flange through the connecting hole, and then flows into the fixed chassis of the cylinder through the check valve to eliminate the bottom pressure. When the cylinder of the pump station is full of water, outward pressure is formed on the bottom of the fixed chassis. Because of the action of the check valve, the water inside the pump station will not flow out of the cylinder, that is, the water in the pump station will not flow out through the short-circuit flange, avoiding internal water from polluting the groundwater. It is particularly suitable for sewage pumping stations. By introducing groundwater into the pump station, the pressure generated by the groundwater is eliminated, thereby playing an anti-floating role.

[0024] 2. By setting up an annular water tank, when the anti-floating device for the integrated prefabricated pump station is used, the anti-floating water storage capacity of the pump station is improved, and at the same time, the groundwater that generates buoyancy can be converted into the counterweight water of the pump station, thereby improving the stability of the pump station and playing the role of anti-floating reinforcement of the pump station;

[0025] When in use, the annular water tank can not only perform temporary water storage operations, but also increase the weight of the fixed chassis and improve the anti-floating effect of the fixed chassis. The annular water tank is fixed to the outside of the fixed chassis using the upper fixing ring and the lower fixing ring. When the annular water tank is full of water, the annular water tank applies its own weight to the fixed chassis, increasing the weight of the fixed chassis and improving the anti-floating effect of the fixed chassis. Secondly, because the prefabricated pump station is installed underground, the annular water tank and the fixed chassis are both buried underground. The exhaust pipe is set to exhaust the inside of the annular water tank during the water storage operation. At the same time, the pouring of concrete can Increase the weight of the fixed chassis and improve the anti-floating effect of the fixed chassis. Secondly, when the reinforcement is docking with the soil, first insert the soil-breaking cone at the lower end of the reinforcement into the soil, so that the entire reinforcement is placed in the soil during the downward pressure process. At this time, the side of the side-rotating cone is in contact with the soil. When the soil-breaking cone and the fixed plug rod move up, the side-rotating cone opens outward with the elastic hinge, and the threaded rod is rotated by the rotating wheel, so that the threaded rod can drive the soil-breaking cone and the fixed plug rod to move up, while keeping the connecting rod in position unchanged, so that the side-rotating cone opens outward and is inserted into the inner side of the soil, and then the connecting rod is connected to the bottom of the annular water tank to complete the reinforcement operation of the annular water tank.

[0026] 3. By setting up a drainage pipe, when the anti-floating device for the integrated prefabricated pump station is used, its bottom has a fully covered drainage structure to prevent the bottom of the pump station from contacting the groundwater and preventing it from rusting. At the same time, it can filter out the sediment in the groundwater and improve its anti-floating stability;

[0027] During operation, the drain board adopts a full-coverage structure design, so that the drain board covers the bottom of the fixed chassis as a whole, and drainage operations can be performed at any position on the bottom of the fixed chassis. The water can be transported to the first water tank or the second water tank through the drain board and the connecting pipe. At the same time, because the groundwater contains a lot of sediment, in order to avoid blockage of the pipeline, the sediment can be filtered by adding a filter plate. The sealing ring can improve the sealing between the drain board and the fixed chassis when they are connected. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0036] like Figure 1 As shown, an anti-floating device for an integrated prefabricated pump station includes a fixed chassis 6 and an anti-floating device 7. The anti-floating device 7 is fixedly installed on the outer surface of the upper end of the fixed chassis 6. The bottom of the fixed chassis 6 is provided with a connecting hole 4 used in conjunction with the anti-floating device 7. An annular water tank 8 is fixedly installed on the outer surface of the fixed chassis 6, and a reinforcement member 1 is fixedly installed on the bottom outer surface of the annular water tank 8; the anti-floating device 7 includes a short-circuit flange 19, a first connecting pipe 21 and a second connecting pipe 22. The first connecting pipe 21 is fixedly installed on the outer surface of one side of the short-circuit flange 19, and the second connecting pipe 22 is fixedly installed on the outer surface of the other side of the short-circuit flange 19. A check valve is provided at the end of the first connecting pipe 21, and an electric control valve 20 is fixedly installed at the end of the second connecting pipe 22. The annular water tank 8 and the second connecting pipe 22 are connected through a drainage pipe 2.

[0037] To solve the floating problem of integrated prefabricated pump station, such as Figure 4As shown, the connecting hole 4 is connected to the lower end of the short-circuit flange 19, and the outer side of the fixed chassis 6 is filled with concrete 5. The cross-section of the fixed chassis 6 is a U-shaped structure. When the groundwater forms pressure on the bottom of the pump station, a connecting hole 4 connected to the short-circuit flange 19 is drilled at the bottom of the pump station. The groundwater flows into the fixed chassis 6 of the pump station cylinder through the connecting hole 4, thereby eliminating the bottom pressure, protecting the safety of the equipment in the pump station, and relieving the pressure on the bottom of the pump station cylinder. The electric control valve 20 can control the opening and closing of the second connecting pipe 22, so that the water body is transported to the fixed chassis 6 or the inside of the annular water tank 8. When there is more groundwater, the second connecting pipe 22 can be opened to transport the water body to the inside of the annular water tank 8.

[0038] To solve the floating problem of prefabricated pump stations, Figure 2 As shown, the upper part of the annular water tank 8 and the fixed chassis 6 are docked and fixed by an upper fixing ring 12, and the lower part of the annular water tank 8 and the fixed chassis 6 are docked and fixed by a lower fixing ring 10. The annular water tank 8 can not only perform temporary water storage operations, but also increase the weight of the fixed chassis 6 and improve the anti-floating effect of the fixed chassis 6. The upper fixing ring 12 and the lower fixing ring 10 are used to fix the annular water tank 8 on the outside of the fixed chassis 6. When the annular water tank 8 is full of water, the annular water tank 8 applies its own weight to the fixed chassis 6, so that the weight of the fixed chassis 6 is increased, and the anti-floating effect of the fixed chassis 6 is improved.

[0039] like Figure 2 As shown, an exhaust pipe 9 is fixedly installed on the outer surface of the upper end of the annular water tank 8, an annular notch 11 is provided inside the annular water tank 8, and a fixed cover plate 23 is fixedly installed on the upper end of the short-circuit flange 19. Because the prefabricated pump station is installed underground, the annular water tank 8 and the fixed chassis 6 are both buried underground. The exhaust pipe 9 is provided to exhaust the inside of the annular water tank 8 when the annular water tank 8 is in water storage operation. At the same time, the pouring of concrete 5 can increase the weight of the fixed chassis 6 and enhance the anti-floating effect of the fixed chassis 6.

[0040] To improve the anti-floating stability of the pump station, Figure 3 As shown, the reinforcement 1 includes a ground-breaking cone 14, a fixed plug rod 15 and a connecting rod 17. The ground-breaking cone 14 is fixedly installed on the outer surface of one end of the fixed plug rod 15, and the connecting rod 17 is movably installed on the outer surface of the other end of the fixed plug rod 15. When the annular water tank 8 is installed underground, the reinforcement 1 can improve the stability of the annular water tank 8 and play a reinforcing role between the annular water tank 8 and the soil.

[0041] Side-rotating cones 13 are movably installed on both sides of the earth-breaking cone 14 and the fixed insertion rod 15. The earth-breaking cone 14 and the side-rotating cone 13 as well as the fixed insertion rod 15 and the side-rotating cone 13 are connected by elastic hinges. When the fixed insertion rod 15 and the side-rotating cone 13 are inserted into the soil, the elastic hinge is used to release the side-rotating cone 13 so that the side-rotating cone 13 is stuck into the soil, so that the reinforcement member 1 and the soil are firmly connected, and the side-rotating cone 13 plays an auxiliary reinforcement role.

[0042] like Figure 3 As shown, the fixed plug rod 15 and the connecting rod 17 are movably connected by a threaded rod 16, and the upper end of the connecting rod 17 is spliced ​​and installed with a rotating wheel 18 used in conjunction with the threaded rod 16. When the reinforcement member 1 is connected to the soil, the soil-breaking cone 14 at the lower end of the reinforcement member 1 is first inserted into the soil, so that the entire reinforcement member 1 is placed in the soil during the downward pressing process. At this time, the side of the side-rotating cone 13 is in contact with the soil, and the side-rotating cone 13 is opened outwardly with the elastic hinge when the soil-breaking cone 14 and the fixed plug rod 15 move up, and the rotating wheel 18 is used to rotate the threaded rod 16, so that the threaded rod 16 can drive the soil-breaking cone 14 and the fixed plug rod 15 to move up, and at the same time, the connecting rod 17 keeps its position unchanged, so that the side-rotating cone 13 is opened outward and inserted into the inner side of the soil, and then the connecting rod 17 is connected to the bottom of the annular water tank 8 to complete the reinforcement operation of the annular water tank 8.

[0043] A drainage board 3 is provided at the bottom of the fixed chassis 6, and a filter plate 26 is provided at the bottom of the drainage board 3. The interior of the drainage board 3 is a hollow structure. The drainage board 3 adopts a full-coverage structure design, so that the drainage board 3 covers the bottom of the fixed chassis 6 as a whole, and drainage operations can be performed at any position on the bottom of the fixed chassis 6. At the same time, because the groundwater contains a large amount of sediment, in order to avoid blockage of the pipeline, the sediment can be filtered by adding a filter plate 26.

[0044] A first water tank 24 is fixedly installed on one side of the drain board 3, and a second water tank 25 is fixedly installed on the other side of the drain board 3. The first water tank 24 and the second water tank 25 are symmetrically arranged, and the first water tank 24 and the second water tank 25 can be used to store the water collected by the drain board 3.

[0045] A sealing ring 28 is fixedly mounted on the outer surface of the upper end of the drain plate 3 , and the drain plate 3 and the first water tank 24 as well as the drain plate 3 and the second water tank 25 are connected through a connecting pipe 27 .

[0046] During use, in order to prevent groundwater from generating buoyancy on the cylinder structure of the integrated pump station, the pump station base generally adopts a U-shaped chassis with grouting holes on the side to prevent buoyancy. However, in areas with abundant groundwater or when the pump station diameter is too large and concrete grouting cannot be in place, after the pump station is installed and backfilled, groundwater will form pressure on the bottom of the pump station, causing the bottom to rise and damage the internal pipeline structure until the pump station is scrapped.

[0047] To this end, by providing an anti-floating device 7, when the anti-floating device for the integrated prefabricated pump station is used, the bottom thereof has a drainage anti-floating structure to prevent the prefabricated pump station from floating up, and groundwater can be introduced into the interior of the pump station, thereby eliminating the bottom pressure of the pump station and improving its stability;

[0048] During operation, when the groundwater forms pressure on the bottom of the pump station, a connecting hole 4 connected to the short-circuit flange 19 is drilled at the bottom of the pump station, and the groundwater flows into the fixed chassis 6 of the pump station cylinder through the connecting hole 4, thereby eliminating the bottom pressure, protecting the safety of the equipment in the pump station, and relieving the pressure on the bottom of the pump station cylinder. The electric control valve 20 can control the opening and closing of the second connecting pipe 22, so that the water body is transported to the fixed chassis 6 or the inside of the annular water tank 8. When there is a lot of groundwater, the second connecting pipe 22 can be opened to transport the water body to the inside of the annular water tank 8. In order to prevent the water in the pump station cylinder from flowing back to the outside of the cylinder, the short-circuit flange 1 The upper end fixed cover plate 23 of 9 is sealed, and a check valve is installed in a tee on the side. When the bottom of the pump station is under pressure, groundwater enters the short-circuit flange 19 through the connecting hole 4, and then flows into the fixed chassis 6 of the cylinder through the check valve to eliminate the bottom pressure. When the cylinder of the pump station is full of water, outward pressure is formed on the bottom of the fixed chassis 6. Because of the effect of the check valve, the water inside the pump station will not flow out of the cylinder, that is, the water in the pump station will not flow out through the short-circuit flange 19, avoiding internal water from polluting the groundwater. It is particularly suitable for sewage pumping stations. By introducing groundwater into the pump station, the pressure generated by the groundwater is eliminated, which plays an anti-floating role.

[0049] Secondly, the traditional integrated pump station has a single anti-floating structure and does not have multiple anti-floating structures. When there is a lot of groundwater, its buoyancy exceeds the anti-floating upper limit of the device, reducing the anti-floating effect of the integrated pump station.

[0050] To this end, by setting up the annular water tank 8, when the anti-floating device for the integrated prefabricated pump station is used, the anti-floating water storage capacity of the pump station is improved, and at the same time, the groundwater that generates buoyancy can be converted into the counterweight water of the pump station, thereby improving the stability of the pump station and playing the role of anti-floating reinforcement of the pump station;

[0051] When in use, the annular water tank 8 can not only perform temporary water storage operations, but also increase the weight of the fixed chassis 6 and improve the anti-floating effect of the fixed chassis 6. The annular water tank 8 is fixed to the outside of the fixed chassis 6 by using the upper fixing ring 12 and the lower fixing ring 10. When the annular water tank 8 is full of water, the annular water tank 8 applies its own weight to the fixed chassis 6, which increases the weight of the fixed chassis 6 and improves the anti-floating effect of the fixed chassis 6. Secondly, because the installation method of the prefabricated pump station is underground installation, the annular water tank 8 and the fixed chassis 6 are both buried underground, and the exhaust pipe 9 is provided to exhaust the inside of the annular water tank 8 when the annular water tank 8 is in water storage operation. At the same time, the pouring of concrete 5 can increase the fixed chassis 6. The weight of the fixed chassis 6 is increased, and the anti-floating effect of the fixed chassis 6 is improved. Secondly, when the reinforcement member 1 is connected to the soil, the soil-breaking cone 14 at the lower end of the reinforcement member 1 is first inserted into the soil, so that the entire reinforcement member 1 is placed in the soil during the downward pressure process. At this time, the side of the side-rotating cone 13 is in contact with the soil. When the soil-breaking cone 14 and the fixed plug rod 15 move up, the side-rotating cone 13 cooperates with the elastic hinge to open outward, and the threaded rod 16 is rotated by the rotating wheel 18, so that the threaded rod 16 can drive the soil-breaking cone 14 and the fixed plug rod 15 to move up, and at the same time, the connecting rod 17 keeps its position unchanged, so that the side-rotating cone 13 opens outward and is inserted into the inner side of the soil, and then the connecting rod 17 is connected to the bottom of the annular water tank 8 to complete the reinforcement operation of the annular water tank 8;

[0052] At the same time, the integrated pump station is installed in an underground structure, so that the bottom of the integrated pump station is in full contact with the soil, which makes the bottom of the integrated pump station prone to rust. In addition, the groundwater is mixed with a large amount of sediment, which blocks the traditional anti-floating structure pipeline and affects its stability.

[0053] To this end, by setting the drainage pipe 2, when the anti-floating device for the integrated prefabricated pump station is used, the bottom thereof has a fully covered drainage structure to prevent the bottom of the pump station from contacting the groundwater and preventing it from rusting. At the same time, the silt in the groundwater can be filtered out to improve its anti-floating stability;

[0054] During operation, the drain board 3 adopts a full-coverage structure design, so that the drain board 3 covers the bottom of the fixed chassis 6 as a whole, and drainage operations can be performed at any position on the bottom of the fixed chassis 6. The water body can be transported to the first water tank 24 or the second water tank 25 through the drain board 3 and the connecting pipe 27. At the same time, because the groundwater contains a large amount of sediment, in order to avoid blockage of the pipeline, the sediment can be filtered by adding a filter plate 26. The sealing ring 28 can improve the sealing between the drain board 3 and the fixed chassis 6 when docking.

[0055] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form.
