Description

Technical Field

[0001] This invention belongs to the field of underground prefabricated pump boxes, and specifically relates to a method for shock absorption installation of underground prefabricated pump boxes. Background Technology

[0002] Prefabricated underground pump units play a crucial role in firefighting. These units integrate the pump and tank into a single, underground assembly, making them widely used due to their minimal space requirements. The integrated pump station utilizes a prefabricated stainless steel or composite stainless steel water tank. The integrated tank rests on a ground beam. Rising groundwater levels generate buoyancy, which can cause the tank to float, tip over, deform, or even be completely flattened. To address this technical challenge, current methods connect the tank's side panels to a reinforced concrete base, eliminating the need for materials and installation at the bottom of the tank. This prevents leakage at the bottom and mitigates the impact of groundwater buoyancy on the tank's base, while also enhancing the structural strength of the tank's bottom.

[0003] Installing water pumps in the pump room of a concrete box pump can cause significant vibrations during operation, particularly affecting the concrete foundation, especially for underground prefabricated box pumps. Due to the unique environment and prolonged vibration, the concrete foundation is prone to cracking. Current installation methods include: first, pouring a concrete foundation containing anchor bolts; then, fitting high-elasticity rubber rings or springs onto the anchor bolts; covering this with a connecting base; finally, tightening the bolts on the connecting base to secure the pump, connecting base, and concrete foundation. The high-elasticity rubber rings or springs dampen the pump's operation, reducing damage to the pump and surrounding equipment. However, these rubber rings or springs must withstand the impact of pump operation. Under prolonged use, the shear hysteresis deformation capacity of the pump is easily damaged by vibration and gravity, resulting in a significant reduction in energy dissipation and vibration reduction performance. Since the underground prefabricated pump box is buried below ground, the damage to the high-elastic rubber ring or spring cannot be visually observed. The deformation of the concrete base and surrounding equipment can only be checked periodically. Moreover, once the concrete base cracks or deforms, or the surrounding equipment is damaged, it is irreversible and the pump box needs to be shut down for repair and replacement. Secondly, because the pump, the connecting base, and the concrete base are connected by bolts, the vibration force of the pump during operation is transmitted to the bolts, causing the bolts to loosen, thereby accelerating the vibration and damage of the pump. Therefore, the installation of the concrete base and the pump in underground prefabricated pump box has always been a difficult technical problem to overcome. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a method for installing shock-absorbing water pumps in underground prefabricated box pumps. This method avoids the situation where the concrete base of the underground prefabricated box pump cracks and deforms, as well as the surrounding equipment, due to the loss of the deformation and rebound ability of the shock-absorbing material after long-term use. It effectively solves the technical problem of installing the concrete base and water pump in underground prefabricated box pumps.

[0005] The objective of this invention is achieved through the following technical solution: a method for vibration damping installation of a buried prefabricated pump box, the specific steps of which include, S1. Excavate the foundation pit in the construction area according to the design dimensions and level the foundation pit. S2. Tie the reinforcing bars at the predetermined positions according to the external frame of the concrete base. When tying the reinforcing bars, reserve multiple rectangular grooves. Fix the positioning template outside the reinforcing bars. Before pouring concrete, embed multiple anchor bolts around the outside of the rectangular grooves. Position the U-shaped embedded pipe with the opening facing the corresponding rectangular groove at the side end of the rectangular groove. Place the end of the U-shaped embedded pipe in the corresponding rectangular groove and tie the U-shaped embedded pipe to the reinforcing bar. Pour concrete into the positioning template to form a concrete base. Place the upper end of the anchor bolt on the upper side of the concrete base. Remove the positioning template. S3. Install a metal buffer body inside the rectangular groove. The outside of the metal buffer body fits into the rectangular groove and is fixedly connected by bolts. Weld the U-shaped pre-embedded pipe to the metal buffer body to fix it. An inwardly recessed cavity is formed inside the metal buffer body. S4. Pour an equal amount of lower damping liquid into each rectangular groove, and install an extrusion connector in the rectangular groove. The outer wall of the extrusion connector is sealed to the inner wall of the metal buffer body, and the extrusion connector divides the chamber into an upper chamber and a lower chamber. The lower damping liquid is placed in the lower chamber. Pour an equal amount of upper damping liquid into the upper chamber of each rectangular groove. The upper end of the U-shaped pre-embedded pipe is connected to the upper chamber, and the lower end of the U-shaped pre-embedded pipe is connected to the lower chamber. A piston is embedded at the top of the metal buffer body. The piston is sleeved on the extrusion connector and is in sealed contact with the inner wall of the metal buffer body. At this time, the upper end of the extrusion connector protrudes from the concrete base. S5. Place a rubber buffer pad on top of the concrete base, with multiple anchor bolts and multiple extruded connectors penetrating the rubber buffer pad. S6. Place a connecting base plate above the rubber buffer pad, install a water pump above the connecting base plate, and pass through the anchor bolts on the base plate of the water pump. Place a disc spring on the position where the anchor bolts are placed above the base plate of the water pump, and put a nut on the disc spring and tighten it.

[0006] A further improvement of the present invention is that: the metal buffer body includes an outer side plate and an outer bottom plate that are fixedly attached to the inner wall of the rectangular groove, and also includes an inner side plate corresponding to the outer side plate and an inner bottom plate corresponding to the outer bottom plate. The inner side plate and the inner bottom plate are connected to each other. The upper ends of the outer side plate and the inner side plate are fixedly connected by a sealing plate and a sealed chamber is formed inside. The sealed chamber contains a storage liquid, and the sealing plate has a liquid injection hole.

[0007] A further improvement of the present invention lies in the installation of the metal buffer body with the rectangular groove and the U-shaped pre-embedded pipe in step S3, specifically including the following steps: S31. Based on the inner wall and bottom dimensions of the rectangular groove, fix the outer side plate of the metal buffer body to the inner side wall of the rectangular groove with bolts, and fix the outer bottom plate of the metal buffer body to the bottom of the rectangular groove with bolts. S32. Weld the U-shaped embedded pipe to the outer side plate at the connection point; S33. Sequentially weld and fix the sealing plate, inner side plate, and inner bottom plate to the outer side plate and outer bottom plate to form the outer frame of the metal buffer body. S34. Weld the connection between the U-shaped embedded pipe and the inner side plate; S35. Fill the sealed chamber of the metal buffer body with storage liquid and seal the injection hole.

[0008] A further improvement of the present invention is that: in step S2, when the reinforcing bars are tied, multiple side transverse reinforcing bars and multiple bottom transverse reinforcing bars are laid along the groove structure of the rectangular groove. Then, multiple side longitudinal reinforcing bars are laid at equal intervals on the outside of the multiple side transverse reinforcing bars. Multiple bottom longitudinal reinforcing bars are laid at equal intervals on the upper side of the multiple bottom transverse reinforcing bars. The lower end of the side longitudinal reinforcing bars is placed on the lower side of the bottom transverse reinforcing bars. The two ends of the bottom longitudinal reinforcing bars are placed on the outside of the side longitudinal reinforcing bars. The bottom transverse reinforcing bars placed on the side ends are placed between the side longitudinal reinforcing bars and the bottom longitudinal reinforcing bars.

[0009] A further improvement of the present invention is that multiple side transverse steel bars and multiple bottom transverse steel bars are distributed at equal intervals in sequence.

[0010] A further improvement of the present invention is that: the extrusion connector includes an extrusion shaft fixedly connected to the bottom of the connecting substrate and a sealing ring placed at the lower end of the extrusion shaft. The sealing ring is fixedly connected to the extrusion shaft, and the outer end face of the sealing ring has a rubber layer that is in sealing contact with the inner wall of the metal buffer. The upper damping fluid and the lower damping fluid are respectively placed at the upper and lower sides of the sealing ring.

[0011] A further improvement of the present invention is that the number of rectangular grooves is 2 or 4, and the rectangular grooves are evenly distributed below the connecting substrate.

[0012] A further improvement of the present invention is that the storage fluid, the upper damping fluid, and the lower damping fluid are all buffer oils.

[0013] Compared with the prior art, the present invention has the following advantages: 1. This invention completes the positioning and installation of U-shaped pre-embedded pipes and anchor bolts before pouring the concrete base. The pre-embedding of the U-shaped pre-embedded pipes provides a foundation for the subsequent positioning and connection with the metal buffer components, while the pre-embedding of the anchor bolts provides a foundation for the subsequent positioning and connection with the rubber buffer pads and connecting base plates. Secondly, this invention integrally forms multiple rectangular grooves on the concrete base through steel bar binding and concrete pouring. The rectangular grooves are positioned and connected to the U-shaped pre-embedded pipes. Before the installation of the connecting base plate and the water pump, the lower damping liquid, the extrusion connector, the upper damping liquid, and the piston are sequentially positioned in the rectangular grooves. Finally, the extrusion connector is welded and fixed to the connecting base plate, forming a dual damping system for the water pump that provides both liquid and rubber damping. This avoids the situation in buried prefabricated pump boxes where the deformation and rebound ability of the damping materials is impaired after long-term use, resulting in cracking and deformation of the concrete base and deformation and damage to surrounding equipment.

[0014] 2. The water pump in this invention generates a certain amount of vibration during operation. The upper and lower ends of the extrusion connector are in contact with the damping liquid. Due to the incompressibility of the damping liquid and its resistance to shear deformation, as the vibration frequency of the extrusion connector is transmitted, the upper and lower damping liquids are regulated through the U-shaped pre-embedded pipe to achieve initial vibration reduction of the extrusion connector. Moreover, the sealing ring at the lower end of the extrusion connector is placed between the damping liquids and subjected to a certain levitation force, which greatly attenuates the vibration frequency, thereby achieving the purpose of vibration reduction. Secondly, when the lower damping liquid in the lower chamber flows into the upper chamber, it will increase the internal pressure of the upper chamber, thereby pushing the piston upward to release the pressure. The piston applies force to the rubber buffer pad, thereby achieving secondary vibration reduction. Furthermore, the extrusion connector is set through the rubber buffer pad. When the extrusion connector vibrates up and down, the friction between the rubber buffer pad and the extrusion connector provides tertiary vibration reduction for the extrusion connector. Therefore, the vibration reduction method of the special structure in this application greatly reduces the vibration frequency of the extrusion connector and the water pump, and avoids the phenomenon of bolt loosening between the water pump base plate and the connecting base plate due to vibration.

Detailed Implementation

For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can be described as a mechanical connection, a direct connection, or a connection through an intermediate medium. Those skilled in the art can understand the basic meaning of the above terms in this invention according to the specific circumstances.

[0024] A method for installing a vibration damping system for a buried prefabricated pump box, comprising the following specific steps: S1. Excavate foundation pit 1 in the construction area according to the design dimensions, and level foundation pit 1. S2, Reference Figure 2Reinforcing bars are tied at predetermined positions according to the external frame of the concrete base 2. Multiple rectangular grooves 3 are reserved during the binding of the reinforcing bars. Positioning template 4 is fixed outside the reinforcing bars. Before pouring concrete, multiple anchor bolts 5 are pre-embedded around the outside of the rectangular grooves 3. A U-shaped pre-embedded pipe 6 with an opening facing the corresponding rectangular groove 3 is positioned at the side end of the rectangular groove 3. The end of the U-shaped pre-embedded pipe 6 is placed in the corresponding rectangular groove 3, and the U-shaped pre-embedded pipe 6 is tied to the reinforcing bars. Concrete is poured into the positioning template 4 to form the concrete base 2. The upper end of the anchor bolt 5 is placed on the upper side of the concrete base 2. The positioning template 4 is then removed. S3. Reference Figure 3 A metal buffer body 7 is installed inside the rectangular groove 3. The outside of the metal buffer body 7 is matched with the rectangular groove 3 and fixed by bolts. The U-shaped pre-embedded pipe 6 is welded and fixed to the metal buffer body 7. An inwardly recessed cavity is formed inside the metal buffer body 7. S4, Reference Figure 5 An equal amount of lower damping liquid 8 is poured into each rectangular groove 3, and an extrusion connector 9 is installed in the rectangular groove 3. The outer wall of the extrusion connector 9 is sealed to the inner wall of the metal buffer body 7, and the extrusion connector 9 divides the chamber into an upper chamber 10 and a lower chamber 11. The lower damping liquid 8 is placed in the lower chamber 11. An equal amount of upper damping liquid 12 is poured into the upper chamber 10 of each rectangular groove 3. The upper end of the U-shaped pre-embedded pipe 6 is connected to the upper chamber 10, and the lower end of the U-shaped pre-embedded pipe 6 is connected to the lower chamber 11. A piston 13 is embedded at the top of the metal buffer body 7. The piston 13 is sleeved on the extrusion connector 9 and is in sealed contact with the inner wall of the metal buffer body 7. At this time, the upper end of the extrusion connector 9 protrudes from the concrete base 2. S5. Reference Figure 4 A rubber buffer pad 14 is placed above the concrete base 2, and multiple anchor bolts 5 and multiple extrusion connectors 9 all penetrate the rubber buffer pad 14. S6. Place the connecting base plate 15 above the rubber buffer pad 14, and install the water pump 16 above the connecting base plate 15. The base plate of the water pump 16 passes through the anchor bolt 5. A disc spring 17 is fitted above the base plate of the water pump 16, and a nut 18 is fitted on the disc spring 17 and tightened. Figure 1 As shown.

[0025] This invention completes the positioning and installation of the U-shaped pre-embedded pipe 6 and anchor bolts 5 before pouring the concrete base 2. The pre-embedding of the U-shaped pre-embedded pipe 6 provides a foundation for the subsequent positioning and connection with the metal buffer 7, while the pre-embedding of the anchor bolts 5 provides a foundation for the subsequent positioning and connection with the rubber buffer pad 14 and the connecting base plate 15. Secondly, this invention integrally forms multiple rectangular grooves 3 on the concrete base 2 through steel bar binding and concrete pouring. The rectangular grooves 3 are positioned and connected to the U-shaped pre-embedded pipe 6. Before the installation of the connecting base plate 15 and the water pump 16, the lower damping liquid 8, the extrusion connector 9, the upper damping liquid 12, and the piston 13 are sequentially positioned in the rectangular grooves 3. Finally, the extrusion connector 9 is welded and fixed to the connecting base plate 15, forming a dual damping system for the water pump 16 that provides both liquid damping and rubber damping. This avoids the situation in the buried prefabricated box pump where the deformation and rebound ability of the damping material is damaged after long-term use, resulting in cracking and deformation of the concrete base and deformation and damage to surrounding equipment.

[0026] The water pump 16 in this invention generates a certain vibration during operation. The upper and lower ends of the extrusion connector 9 are in contact with the damping liquid. Due to the incompressibility of the damping liquid and its resistance to shear deformation, as the vibration frequency of the extrusion connector 9 is transmitted, the upper damping liquid 12 and the lower damping liquid 8 are regulated by the U-shaped pre-embedded pipe 6 to perform initial vibration reduction on the extrusion connector 9. Moreover, the sealing ring 92 at the lower end of the extrusion connector 9 is placed between the damping liquids and subjected to a certain levitation force, which greatly attenuates the vibration frequency, thereby achieving the purpose of vibration reduction. Secondly, when the lower damping liquid 8 in the lower chamber 11 flows into the upper chamber 10, it will increase the internal pressure of the upper chamber 10, thereby pushing the piston 13 upward to release the pressure. The piston 13 applies force to the rubber buffer pad 14, thereby achieving secondary vibration reduction. Furthermore, the extrusion connector 9 is set through the rubber buffer pad 14. When the extrusion connector 9 vibrates up and down, the friction between the rubber buffer pad 14 and the extrusion connector 9 performs tertiary vibration reduction on the extrusion connector 9. Therefore, the vibration reduction method of the special structure in this application greatly reduces the vibration frequency of the extrusion connector 9 and the water pump 16, and avoids the phenomenon of loose bolts between the base plate of the water pump 16 and the connecting base plate 15 due to vibration.

[0027] It should be noted that the vibration reduction of the water pump 16 in this invention is achieved in two aspects: First, by setting the lower damping liquid 8, the extrusion connector 9, the upper damping liquid 12, the piston 13, and the rubber buffer pad 14 in the rectangular groove 3, the vibration frequency of the water pump 16 is reduced through three vibration reductions; Second, the disc spring 17 is set between the nut 18 and the water pump base plate. The disc spring 17 is deformed under the clamping action of the nut 18 and stores a certain potential energy. When subjected to a certain vibration, the disc spring 17 releases part of the potential energy to maintain the pressure on the water pump base plate, effectively realizing the vibration reduction of the water pump 16, thereby preventing the nut 18 from loosening.

[0028] In this embodiment, the metal buffer body 7 includes an outer side plate 71 and an outer bottom plate 72 that are fixedly attached to the inner wall of the rectangular groove 3, and also includes an inner side plate 73 corresponding to the outer side plate 71 and an inner bottom plate 74 corresponding to the outer bottom plate 72. The inner side plate 71 and the inner bottom plate 74 are connected to each other. The upper ends of the outer side plate 71 and the inner side plate 73 are fixedly connected by a sealing plate 75 and a sealed chamber 76 is formed inside. The sealed chamber 76 contains a storage liquid 77, and the sealing plate 75 has an injection hole.

[0029] In this embodiment, the installation of the metal buffer 7 with the rectangular groove 3 and the U-shaped embedded pipe 6 in step S3 specifically includes the following steps: S31. Based on the inner wall and bottom dimensions of the rectangular groove 3, the outer side plate 71 of the metal buffer body 7 is fixed to the inner side wall of the rectangular groove 3 with bolts, and the outer bottom plate of the metal buffer body 7 is fixed to the bottom of the rectangular groove 3 with bolts. S32. Weld the U-shaped embedded pipe 6 to the outer side plate 71 at the connection position; S33. Sequentially weld and fix the sealing plate 75, inner side plate 73 and inner bottom plate 74 to the outer side plate 71 and outer bottom plate 72 to form the outer frame of the metal buffer body 7. S34. Weld the position where the U-shaped embedded pipe 6 connects to the inner side plate 73; S35. Fill the sealed chamber 76 of the metal buffer body 7 with storage liquid 77 and seal the injection hole.

[0030] In this invention, the metal buffer 7 isolates the concrete base 2 from the extrusion connector 9. The metal buffer 7 is connected to the U-shaped pre-embedded pipe 6. The damping liquid is placed in the cavity of the metal buffer 7, which effectively seals the cavity and prevents the damping liquid from leaking out and affecting the shock absorption performance of the water pump 16. At the same time, the metal buffer 7 has a storage liquid 77 inside, which further reduces the vibration of the extrusion connector 9. Importantly, the storage liquid 77 and the damping liquid also have a good sound absorption effect, preventing the buried prefabricated pump from generating noise that affects the surrounding environment.

[0031] In this embodiment, during step S2, when binding the reinforcing bars, multiple side transverse reinforcing bars 19 and multiple bottom transverse reinforcing bars 20 are laid along the groove structure of the rectangular groove 3. Then, multiple side longitudinal reinforcing bars 21 are laid at equal intervals on the outside of the multiple side transverse reinforcing bars 19. Multiple bottom longitudinal reinforcing bars 22 are laid at equal intervals on the upper side of the multiple bottom transverse reinforcing bars 20. The lower end of the side longitudinal reinforcing bars 21 is placed on the lower side of the bottom transverse reinforcing bars 20, and both ends of the bottom longitudinal reinforcing bars 22 are placed on the outside of the side longitudinal reinforcing bars 21. The bottom transverse reinforcing bars 20 placed on the side are placed between the side longitudinal reinforcing bars 21 and the bottom longitudinal reinforcing bars 22.

[0032] In this embodiment, multiple side transverse steel bars 19 and multiple bottom transverse steel bars 20 are distributed at equal intervals in sequence.

[0033] Since a rectangular groove 3 needs to be reserved on the concrete base 2, a special steel bar binding method is required at the corner of the rectangular groove 3 to improve the structural strength of the recessed position of the rectangular groove 3. This provides a basic guarantee for the subsequent installation of the metal buffer 7, U-shaped embedded pipe 6, lower damping liquid 8, extrusion connector 9, upper damping liquid 12 and piston 13, and avoids the concrete base 2 from cracking due to the vibration of many water pumps in the pump box.

[0034] In this embodiment, the extrusion connector 9 includes an extrusion shaft 91 fixedly connected to the bottom of the connecting substrate 15 and a sealing ring 92 located at the lower end of the extrusion shaft 91. The sealing ring 92 is fixedly connected to the extrusion shaft 91, and the outer end face of the sealing ring 92 has a rubber layer 93 that is in sealing contact with the inner wall of the metal buffer body 7. The upper damping liquid 12 and the lower damping liquid 8 are respectively located at the upper and lower sides of the sealing ring 92.

[0035] In this invention, the sealing ring 92 at the lower end of the extrusion shaft 91 is placed between the upper damping liquid 12 and the lower damping liquid 8. Therefore, the entire extrusion connector 9 is subjected to the levitation force of the damping liquid. This levitation force can counteract the gravity of the water pump 17 and the connecting base plate 15, keeping them in balance. When the water pump vibrates, the damping liquid and the piston 13 can also dampen and buffer the extrusion connector 9 and the water pump 17.

[0036] In this embodiment, there are two or four rectangular grooves 3, and the rectangular grooves 3 are evenly distributed below the connecting substrate 15.

[0037] In this embodiment, the storage fluid 77, the upper damping fluid 12, and the lower damping fluid 8 are all buffer oils.

[0038] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
