Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a construction method for the structure and equipment installation of a water pumping station. Background Technology

[0002] A pump house is a building used to install water pumps, motors, pump control cabinets, and other auxiliary equipment. Its main purpose is to protect the pump units and auxiliary equipment from damage caused by environmental factors. With the rapid improvement of my country's socio-economic level and the accelerating pace of urbanization, the water pressure and volume of municipal water supply are increasingly unable to meet the water needs of residents.

[0003] To address the aforementioned issues, existing technologies typically involve renovating or expanding existing pumping stations based on actual conditions. During this renovation / expansion process, to avoid disrupting residents' daily lives and production, the water supply equipment within the original pumping station is usually kept running continuously. However, the renovation and construction of the pumping station generates a large amount of dust. Under the influence of static electricity, this dust adheres to various parts of the water supply equipment, increasing the probability of equipment malfunction and damage, reducing the effective water supply time of the pumping station, and causing inconvenience to residents' daily lives and production.

[0004] Therefore, how to prevent construction dust from adsorbing onto the operating water supply equipment during the renovation / expansion of pump rooms is a technical problem that urgently needs to be solved in the existing technology. Summary of the Invention

[0005] The purpose of this invention is to address the problem that, during the renovation / expansion of existing water pumping stations, the water supply equipment inside is usually kept running continuously to avoid affecting the daily lives and production of residents. However, the renovation and construction of water pumping stations generate a large amount of dust, which, under the influence of static electricity, adheres to various parts of the water supply equipment, increasing the probability of equipment malfunction and damage, reducing the effective water supply time of the pumping station, and causing inconvenience to residents' lives and production. This invention provides a method for constructing a water pumping station and installing the equipment.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A pump house structure includes a demolition area and a working area. The demolition area is the construction area for the renovation / expansion of the pump house, and the working area is the placement area for the original water supply equipment of the pump house. A dust-blocking component is provided between the working area and the demolition area to prevent dust generated during construction in the demolition area from spreading to the working area. The dust-blocking component includes a mounting bracket and an isolation membrane. The mounting bracket is disposed opposite to the top plate and the floor of the working area and is used to fix the isolation membrane. A ventilation component and an exhaust component are also provided in the working area. The ventilation component is used to draw air from the external environment into the working area, and the exhaust component is used to exhaust air from the working area to the external environment.

[0008] Preferably, the ventilation component includes a first exhaust fan, a second exhaust fan, a first air inlet pipe, and a second air inlet pipe. The first exhaust fan is connected to the first air inlet pipe, and the second exhaust fan is connected to the second air inlet pipe. The first air inlet pipe is arranged along the top plate of the working area, and the second air inlet pipe is arranged along the floor of the working area. The outlet ends of the first air inlet pipe and the second air inlet pipe are also connected to a plurality of air supply pipes. The air supply pipes are arranged at intervals along the isolation film, and the ends of the air supply pipes are also connected to air vents. The air vents are fixed on the mounting base. The air vents located on the top plate of the working area are oriented towards the floor of the working area, and the air vents located on the floor of the working area are oriented towards the top plate of the working area.

[0009] Preferably, the width of the isolation film is greater than the floor height of the pump room.

[0010] Preferably, the air outlet includes a connecting section, an elbow section, and an air nozzle section. The connecting section is fixed on the mounting bracket, and the elbow section is disposed between the connecting section and the air nozzle section.

[0014] Preferably, the flow rate of air drawn into the operating zone by the ventilation component from the external environment is greater than the flow rate of air discharged from the operating zone to the external environment by the exhaust component.

[0015] Preferably, the ventilation component is installed on the wall opposite the isolation film in the working area, and the distance between the ventilation component and the top plate of the working area is equal to the distance between the ventilation component and the floor of the working area.

[0016] Preferably, the insulating film is provided with a plurality of reflective marking strips.

[0017] Preferably, the wall of the working area and / or the demolition area is provided with a through hole, and a bushing is provided inside the through hole. A water supply pipe and / or a drainage pipe pass through the bushing. The bushing includes a pipe body and a rubber pad.

[0018] Preferably, the wall of the working area corresponds to the area where the through hole is set, and the internal steel reinforcement is set as a dense structure.

[0019] Preferably, a gap is provided between the inner wall of the through hole and the outer wall of the bushing tube.

[0026] Step 5: Installation of equipment and facilities in the pump room renovation / expansion area;

[0027] Step Six: Dismantling and cleaning of temporary facilities in the pump room.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. The pump room structure described in this invention includes a dust-blocking component installed between the demolition area and the working area. This component prevents dust generated during demolition from spreading to the working area and avoids the dust from adhering to the water supply equipment in the working area due to electrostatic effects, thus ensuring the stable operation of the water supply equipment in the working area. Furthermore, this embodiment also considers that the dust-blocking component, after its installation, will compress the heat dissipation space of the water supply equipment in the working area. The heat generated by the water supply equipment during operation is difficult to dissipate quickly, and the probability of malfunction and damage to the water supply equipment operating in the working area under long-term high-temperature conditions will increase. Therefore, this embodiment also includes a ventilation component and an exhaust component in the working area. The ventilation component and exhaust component work together to accelerate the interaction rate between the air in the working area and the external ambient air. This allows the heat generated by the water supply equipment in the working area to be quickly discharged to the external environment, further ensuring the stable operation of the water supply equipment in the working area.

[0030] 2. A pump room structure according to the present invention, wherein the ventilation component includes a first exhaust fan, a second exhaust fan, a first air inlet pipe, and a second air inlet pipe. The first exhaust fan is connected to the first air inlet pipe, and the second exhaust fan is connected to the second air inlet pipe. The first air inlet pipe is arranged along the ceiling of the working area, and the second air inlet pipe is arranged along the floor of the working area. A plurality of air supply pipes are also connected to the outlet ends of the first and second air inlet pipes. The air supply pipes are spaced apart along the insulating film, and each end of the air supply pipe is connected to an air outlet, which is fixed on the mounting bracket. The air vents on the ceiling of the working area are oriented towards the floor of the working area, while the air vents on the floor of the working area are oriented towards the ceiling. The air vents are fixed to the mounting brackets, allowing the airflow to get closer to the isolation film. This causes the isolation film to vibrate / sway under the influence of the airflow, preventing dust generated during demolition from adhering to the isolation film. When the isolation film is removed after construction, dust adhering to the film can be removed without contaminating the internal environment of the pump room. Furthermore, the air vents on the ceiling of the working area are oriented towards the floor, while the air vents on the floor are oriented towards the ceiling. This configuration allows the airflow from the vents on the ceiling and the floor to collide, creating turbulence. This turbulence further causes the isolation film to vibrate / sway, further suppressing dust generated during demolition from adhering to the isolation film.

[0031] 3. In the pump room structure described in this invention, the nozzle section is fitted to the isolation membrane; the cross-section of the nozzle section is flat; and the area of ​​the isolation membrane corresponding to the area below the nozzle section is roughened. This allows for a faster airflow velocity from the nozzle section, and the airflow can quickly flow over the surface of the isolation membrane. When the airflow rapidly passes over the roughened surface of the isolation membrane, it causes the membrane in that area to vibrate at a high frequency, causing the dust accumulated in that area to fall off, thereby further preventing dust adhering to the isolation membrane from contaminating the internal environment of the pump room.

[0032] 4. In the pump house structure described in this invention, a gap is provided between the inner wall of the through hole and the outer wall of the bushing. A plurality of threaded support columns are provided on the inner wall of the through hole, and a plurality of load-bearing support columns are correspondingly provided on the pipe body. A push sleeve is provided between the threaded support columns and the load-bearing support columns. The push sleeve includes a threaded section and a hollow section. The threaded support column is connected to the threaded section, and the load-bearing support column is inserted into the hollow section. The bushing is configured with a separable first half and a second half along its diameter. Adjusting the push sleeve to move it towards the load-bearing support column allows the first half and the second half to combine into a whole. Adjusting the push sleeve to move it towards the threaded support column allows the first half and the second half to separate. This structural design allows the bushing to be replaced without damaging the pump house wall structure when it ages and fails, improving the practicality of this invention in actual use. Furthermore, in this embodiment, during installation, the rubber pad layer does not deform along the central axis of the bushing, thus ensuring that the bushing can effectively absorb vibrations generated by the water supply and drainage pipes. Furthermore, the pipe body is provided with several slots. This structural design allows workers to observe the aging and wear of the rubber pad layer through these slots, ensuring that the bushing can be replaced promptly after aging and failure. Moreover, the presence of these slots allows the drainage of any voids in the cracks of the rubber pad layer when vibrations from the water supply and / or drainage pipes compress and deform it, preventing further damage to the bushing and extending its service life to some extent.

[0049] Example 1

[0050] like Figures 1 to 5 As shown, the pump house structure of the present invention includes a demolition area 1 and a working area 2. The demolition area 1 is the construction area for the renovation / expansion of the pump house, and the working area 2 is the placement area for the original water supply equipment of the pump house. A dust-blocking component 3 is provided between the working area 2 and the demolition area 1. The dust-blocking component 3 is used to prevent dust generated during the construction in the demolition area 1 from spreading to the working area 2. The dust-blocking component 3 includes a mounting base 4 and an isolation film 5. The mounting base 4 is disposed opposite to the top plate and the floor of the working area 2. The mounting base 4 is used to fix the isolation film 5. The working area 2 is also provided with a ventilation component 6 and an exhaust component 7. The ventilation component 6 is used to draw air from the external environment into the working area 2, and the exhaust component 7 is used to exhaust the air in the working area 2 to the external environment.

[0051] The pump house structure described in this invention includes a dust-blocking component 3 installed between the demolition area 1 and the operating area 2. This prevents dust generated during construction in the demolition area 1 from spreading to the operating area 2, and avoids the dust from being adsorbed onto the water supply equipment in the operating area 2 due to electrostatic effects, thus ensuring the stable operation of the water supply equipment in the operating area 2. Furthermore, this embodiment also considers that the dust-blocking component 3, after its installation, will compress the heat dissipation space of the water supply equipment in the operating area 2. The heat generated by the operation of the water supply equipment will be difficult to dissipate quickly, and the probability of malfunction and damage to the water supply equipment in the operating area 2 will increase due to prolonged operation in a high-temperature environment. Therefore, this embodiment also includes a ventilation component 6 and an exhaust component 7 in the operating area 2. The ventilation component 6 and the exhaust component 7 work together to accelerate the interaction rate between the air in the operating area 2 and the external ambient air. This allows the heat generated by the operation of the water supply equipment in the operating area 2 to be quickly discharged to the external environment, further ensuring the stable operation of the water supply equipment in the operating area 2.

[0052] Specifically, in this embodiment, the card holder 4 is fixed to the top plate and floor of the working area 2 by expansion bolts. The card holder 4 includes a base body, which is fixed to the top plate and floor of the working area 2 by expansion bolts. The base body is provided with a snap-fit ​​groove, and a plurality of pressure blocks are spaced apart on one side wall of the snap-fit ​​groove. The pressure blocks are threadedly engaged with the side wall of the snap-fit ​​groove. Tightening the pressure blocks can move them closer to the side wall of the snap-fit ​​groove on the other side, or tightening the pressure blocks can move them away from the side wall of the snap-fit ​​groove on the other side. When the isolation film 5 is connected to the card holder 4, the edge portion of the isolation film 5 is inserted into the card slot. After slight adjustment, the pressure block is twisted to move it towards the side wall of the card slot on the opposite side, thus clamping the isolation film 5 in the card slot. When disconnecting the isolation film 5 from the card holder 4, the pressure block is twisted in the opposite direction to move it away from the side wall of the card slot, allowing the isolation film 5 to be removed from the card slot. Further, in this embodiment, the isolation film 5 is a polyethylene plastic film, and the portion of the isolation film 5 that mates with the card slot is designed with a thickened structure, and / or, the portion of the isolation film 5 that mates with the card slot has several fixing holes through which the pressure block can pass. This structural design prevents the portion of the isolation film 5 clamped in the card slot from being damaged by the pressure block; and this structural design ensures the stability of the connection between the isolation film 5 and the card holder 4.

[0053] As a preferred embodiment, based on the above method, the ventilation component 6 further includes a first exhaust fan 8, a second exhaust fan 9, a first air inlet pipe 10, and a second air inlet pipe 11. The first exhaust fan 8 is connected to the first air inlet pipe 10, and the second exhaust fan 9 is connected to the second air inlet pipe 11. The first air inlet pipe 10 is arranged along the top plate of the working area 2, and the second air inlet pipe 11 is arranged along the floor of the working area 2. The outlet ends of the first air inlet pipe 10 and the second air inlet pipe 11 are also connected to a plurality of air supply pipes 12. The air supply pipes 12 are arranged at intervals along the isolation film 5. The ends of the air supply pipes 12 are also connected to air outlets 13. The air outlets 13 are fixed on the card seat 4. The air outlets 13 located on the top plate of the working area 2 are oriented towards the floor of the working area 2, and the air outlets 13 located on the floor of the working area 2 are oriented towards the top plate of the working area 2.

[0054] Specifically, in this embodiment, both the first exhaust fan 8 and the second exhaust fan 9 are installed in the working area 2. The first air inlet pipe 10 and the second air inlet pipe 11 are arranged straight along the ceiling and floor of the working area 2, respectively, thus reducing the loss of airflow velocity. A diversion adapter is provided at the outlet of the first air inlet pipe 10 and the second air inlet pipe 11, and the air supply pipe 12 is connected to the diversion adapter. In this embodiment, the air outlet 13 is fixed to the mounting bracket 4, so that the airflow from the air outlet 13 can get closer to the isolation film 5. The isolation film 5 can vibrate / sway under the influence of the airflow, thus preventing dust generated during construction in the removal area 1 from adhering to the isolation film 5. When the isolation film 5 is removed after construction, the dust adhering to the isolation film 5 can be prevented from polluting the internal environment of the pump room. Furthermore, the air outlet 13 located on the top plate of the working area 2 is positioned so that its air outlet direction faces the floor of the working area 2, while the air outlet 13 located on the floor of the working area 2 is positioned so that its air outlet direction faces the top plate of the working area 2. With this structural arrangement, the airflow blown from the air outlet 13 on the top plate of the working area 2 and the airflow blown from the air outlet 13 on the floor of the working area 2 can collide to form turbulence. As a result, the isolation film 5 can better vibrate / sway under the impetus of the turbulence, further suppressing the dust generated during the demolition area 1 construction from adhering to the isolation film 5.

[0055] On another front, the isolation film 5, driven by airflow, vibrates / oscillates, which in turn promotes airflow in the demolition area 1, reducing dust accumulation and improving the working environment for workers. Furthermore, the vibration / oscillation of the isolation film 5 also makes the boundary between the demolition area 1 and the working area 2 more distinct, providing a stronger warning to construction workers and reducing the risk of construction equipment intruding into the working area 2 and damaging its internal water supply equipment.

[0056] As a preferred embodiment, based on the above method, the width of the isolation film 5 is greater than the floor height of the pump room.

[0057] Specifically, in this embodiment, the width of the isolation film 5 is 1.1 to 1.2 times the height of the pump room. With this structural arrangement, the isolation film 5 can generate a greater amplitude of vibration / swaying under the action of airflow, thereby further suppressing the adhesion of dust generated during the demolition area 1 to the isolation film 5.

[0058] Example 2

[0059] like Figure 4 As shown, the pump room structure of the present invention, based on the above method, further includes a connecting section 14, an elbow section 15, and a nozzle section 16. The connecting section 14 is fixed on the card seat 4, and the elbow section 15 is disposed between the connecting section 14 and the nozzle section 16. The bending angle of the elbow section 15 is adjustable.

[0060] Specifically, in this embodiment, the connecting section 14 connects to the end of the air supply pipe 12, and the base body is provided with several retaining rings at intervals, with the connecting section 14 snapped into the retaining rings; the elbow section 15 is a malleable corrugated pipe. In this embodiment, by adjusting the bending angle of the elbow section 15, the direction of the airflow from the air outlet 13 can be changed, and thus the angle and area of ​​airflow collision can be adjusted according to the actual construction situation, improving the practicality of the invention in actual use.

[0061] Example 3

[0062] like Figures 1 to 5 As shown, in the pump room structure of the present invention, based on the above-mentioned method, the nozzle section 16 is further provided to be attached to the isolation film 5; the cross-section of the nozzle section 16 is set as a flat structure; and the area of ​​the isolation film 5 corresponding to the area below the nozzle section 16 is set as a rough surface.

[0063] In the above embodiment, the air outlet 13 located on the top plate of the working area 2 is oriented towards the floor of the working area 2, and the air outlet 13 located on the floor of the working area 2 is oriented towards the top plate of the working area 2. With this structural arrangement, the airflow from the air outlet 13 on the top plate of the working area 2 collides with the airflow from the air outlet 13 on the floor of the working area 2 to form turbulence. As a result, the isolation film 5 can better vibrate / oscillate under the impetus of the turbulence, further suppressing the dust generated during the demolition area 1 from adhering to the isolation film 5. However, there are still shortcomings. Due to the restriction of the card holder 4, the degree of freedom of movement of the area where the isolation film 5 is connected to the card holder 4 is small. In addition, the turbulence generated by the airflow collision is difficult to diffuse to the area of ​​the card holder 4, resulting in a small amplitude and frequency of vibration / oscillation in the area where the isolation film 5 is connected to the card holder 4. This makes it difficult for the dust adsorbed in this area to fall off. In the case of a long construction period, a large amount of dust will still accumulate on the isolation film 5 in the area where it is connected to the card holder 4. Based on this, in this embodiment, the nozzle section 16 is configured to be attached to the isolation film 5; the cross-section of the nozzle section 16 is configured as a flat structure; and the area of ​​the isolation film 5 corresponding to the area below the nozzle section 16 is configured as a rough surface. In this way, the airflow velocity from the nozzle section 16 can be increased, and the airflow can quickly flow over the surface of the isolation film 5. When the airflow quickly flows over the rough surface of the isolation film 5, it can cause the isolation film 5 in that area to generate high-frequency vibrations, causing the dust accumulated in that area to fall off, thereby further preventing the dust attached to the isolation film 5 from contaminating the internal environment of the pump room.

[0064] As a preferred embodiment, based on the above method, the flow rate of air drawn into the working zone 2 by the ventilation component 6 from the external environment is greater than the flow rate of air discharged from the working zone 2 to the external environment by the exhaust component 7. With this structural arrangement, the airflow blown from the vent 13 on the top plate of the working zone 2 collides with the airflow blown from the vent 13 on the floor of the working zone 2 to form turbulence, which can be better diffused. Consequently, the isolation film 5 can better vibrate / oscillate under the impetus of the turbulence, further suppressing the adhesion of dust generated during the demolition area 1 to the isolation film 5.

[0065] Example 4

[0066] like Figure 5As shown, the pump house structure of the present invention, based on the above-described method, further includes a plurality of reflective marking strips 17 provided on the isolation membrane 5. With this structural arrangement, the reflective marking strips 17 can sway with the isolation membrane 5 under the propulsion of airflow, further enhancing the warning effect on construction personnel and reducing the risk of construction equipment intruding into the working area 2 and damaging its internal water supply equipment.

[0067] Example 5

[0068] like Figures 6 to 8 As shown, the pump room structure of the present invention, based on the above-described method, further includes a through hole 18 provided on the wall of the working area 2 and / or the demolition area 1. A bushing 19 is provided inside the through hole 18, through which a water supply pipe and / or a drainage pipe pass. The bushing 19 includes a pipe body 20 and a rubber pad 21. The rubber pad 21 is in contact with the wall of the water supply pipe and / or the drainage pipe. The bushing 19 is used to prevent vibrations generated by the water supply pipe and / or the drainage pipe from being transmitted to the wall of the working area 2.

[0069] During the operation of a pump room, a sudden power outage or a valve closing too quickly can cause the pressurized water flow to generate a water hammer effect due to inertia. When this effect occurs, the high-pressure water strongly impacts the walls of the water supply and drainage pipes, causing them to vibrate intensely. This vibration is transmitted to the pump room's wall structure when the pipes pass through them, increasing the risk of wall cracking and damage. Therefore, this embodiment includes the bushing 19. When the water hammer effect occurs, the rubber pad 21 absorbs the vibration from the water supply and drainage pipes, preventing the vibration from being transmitted to the pump room's wall structure and thus reducing the risk of wall cracking and damage due to vibration.

[0070] As a preferred embodiment, based on the above method, the wall of the working area 2 corresponding to the area where the through hole 18 is set has a reinforced internal steel reinforcement structure. This structural arrangement further strengthens the wall structure in the area of ​​the through hole 18, further reducing the risk of cracking and damage to the pump room wall due to vibration.

[0071] As a preferred embodiment, based on the above method, a gap is further provided between the inner wall of the through hole 18 and the outer wall of the bushing tube 19. A plurality of threaded support columns 22 are provided on the inner wall of the through hole 18, and a plurality of load-bearing support columns 23 are correspondingly provided on the tube body 20. A push sleeve 24 is provided between the threaded support columns 22 and the load-bearing support columns 23. The push sleeve 24 includes a threaded section 25 and a hollow section 26. The threaded support columns 22 are connected to the threaded section 25, and the load-bearing support columns 23 are inserted into the hollow section 26. The bushing is configured along its diameter as a separable first half-sleeve 27 and a second half-sleeve 28. Adjusting the push sleeve 24 to move it towards the load-bearing support column 23 can make the first half-sleeve 27 and the second half-sleeve 28 combine to form a whole. Adjusting the push sleeve 24 to move it towards the threaded support column 22 can separate the first half-sleeve 27 and the second half-sleeve 28.

[0072] This structural design allows for replacement of the bushing 19 without damaging the pump room wall structure when it ages and fails, improving the practicality of the invention in actual use. Furthermore, in this embodiment, during installation, the rubber pad 21 does not deform along the central axis of the bushing 19, thus ensuring that the bushing 19 can effectively absorb vibrations generated by the water supply and drainage pipes.

[0073] Specifically, in this embodiment, when the bushing 19 reaches the end of its service life and needs to be replaced, the push sleeve 24 is turned to move it towards the threaded support column 22. After the load-bearing support column 23 exits from the cavity section 26, the first half-sleeve 27 and the second half-sleeve 28 can be removed from the water supply pipe and / or, drainage pipe through the gap between the inner wall of the through hole 18 and the outer wall of the bushing 19. When installing the bushing 19, the first half-sleeve 27 and the second half-sleeve 28 are fitted against the water supply pipe and / or, drainage pipe through the gap between the inner wall of the through hole 18 and the outer wall of the bushing 19. After the load-bearing support column 23 and the threaded support column 22 are aligned one-to-one, the push sleeve 24 is turned to move it towards the load-bearing support column 23 until the first half-sleeve 27 and the second half-sleeve 28 are combined to form a whole and are stably connected to the water supply pipe and / or drainage pipe.

[0074] As a preferred embodiment, based on the above method, the tube body 20 is further provided with a plurality of slots 29.

[0075] Compared to the existing technology where the bushing 19 is pre-embedded in the wall structure of the pump room, this embodiment allows workers to observe the aging and wear of the rubber pad 21 through the slots 29 provided on the pipe body 20, ensuring that the bushing 19 can be replaced in a timely manner after aging and failure.

[0076] Furthermore, considering that in the prior art, when the rubber pad 21 ages and develops through cracks, air can enter the cracks. When the vibrations from the water supply pipe and / or drainage pipe deform the rubber pad 21, the air in the cracks cannot escape and is forced towards the connection between the rubber pad 21 and the pipe body 20. Over time, the high-pressure air will damage the connection between the rubber pad 21 and the pipe body 20, further aggravating the damage to the bushing 19 and shortening its service life. In this embodiment, several slots 29 are provided on the pipe body 20. When the vibrations from the water supply pipe and / or drainage pipe compress the rubber pad 21 and deform it, the air in the cracks of the rubber pad 21 can be discharged through the slots 29, preventing further damage to the bushing 19 and extending its service life to a certain extent.

[0077] Example 6

[0078] like Figures 1 to 9 As shown, the installation and construction method for a water pumping station equipment according to the present invention includes the following steps:

[0079] Step 1: Protection of existing equipment and facilities in the pump room, and removal of old equipment and facilities;

[0080] Step 2: Erecting safety protection measures in the construction area of ​​the pump room renovation / expansion project;

[0081] Step 3: Establishment of dust isolation measures between the existing equipment and facilities area of ​​the pump room and the renovation / expansion construction area;

[0082] Step 4: Construction of the pump room renovation / expansion area;

[0083] Step 5: Installation of equipment and facilities in the pump room renovation / expansion area;

[0084] Step Six: Dismantling and cleaning of temporary facilities in the pump room.

[0085] Specifically, in this embodiment, in step one, the pipes and pumps at the intersection construction sites need to be protected before construction. The specific method is as follows: A48 steel pipes are used to build a protective cage, and a 9mm thick template is laid on the protective cage. For areas involving demolition, opening, etc., where construction debris may damage the walls and floors, a 9mm thick board is laid at the bottom to protect the floor and walls. The remaining construction areas are covered with tarpaulins. Construction debris generated during construction is promptly cleaned up, bagged, and transported away.

[0086] In step two, a protective frame is erected between the existing equipment and facilities area of ​​the pump house and the renovation / expansion construction area to prevent workers from freely entering and exiting working area 2 and affecting the normal production of the water plant. A48 steel pipes are used for the frame, with a height of 1.8m.

[0087] In step three, a membrane is hung between the original equipment and facilities installation area of ​​the pump room and the renovation / expansion construction area to separate the two areas. Air supply and exhaust fans are used to promptly remove air from the original equipment and facilities installation area of ​​the pump room to ensure that the equipment has a good operating environment. For machinery and equipment that cannot be isolated, they are shielded or wrapped (equipment that requires heat dissipation and ventilation must not be wrapped).

[0088] Step four involves the construction of the pump room renovation / expansion area, including:

[0089] Dismantling of railings: (1) Dismantling of handrail tubes: Use a handheld cutting machine to cut them to a certain length, and also cut the welded position to the column. Collect the dismantled stainless steel tubes with a labor cart and pile them in the designated location; (2) Dismantling of columns: After the stainless steel tubes are dismantled, dismantle the stainless steel columns; (3) Cleaning up of dismantling waste: After the railings are dismantled, transport the waste to the designated storage point outside the pump room; (4) Dismantling waste should be cleaned up in time to prevent accidents caused by workers stepping on it during construction.

[0090] Steel ladder dismantling: (1) Before dismantling the steel ladder, a temporary walkway with concrete walkway slabs should be erected first so that personnel can go up and down after the steel ladder is dismantled; (2) Use a cutting machine to cut the connection between the steel ladder and the base plate, and then cut the connection between the steel ladder and the concrete walkway slab, and slowly put the steel ladder on the ground; (3) After the steel ladder is dismantled, the waste materials should be transported to the outside of the site for unified storage in a timely manner.

[0091] Concrete walkway cutting and demolition: (1) According to the design requirements, the concrete walkway slabs and beams need to be removed when demolishing the concrete walkway slabs. The concrete walkway should be demolished by pneumatic hammers first, and the steel bar connection should be cut with a water-cooled cutting machine. (2) Before demolishing the concrete walkway slabs, a demolition plan should be formulated. (3) Start from the gap between the cantilever beam and the cantilever beam slabs and use pneumatic hammers to break and peel off the concrete blocks until the steel bars are exposed. Then use a cutting machine to cut off the steel bar skeleton between the slabs. Continue to demolish the concrete walkway slabs in this way. (4) After the demolition is completed, the broken surface is leveled with 1:2 cement mortar. (5) When cutting the steel bars, the workers must wear safety belts and goggles correctly to prevent the collapse of the steel bar skeleton and the injury caused by the broken steel bars. (6) Workers should be arranged to clean up the construction waste at any time during the demolition.

[0092] Opening sealing: The steel casing is sealed according to the location specified in the design drawings. The inside of the casing is filled with C40 micro-expansion fine aggregate concrete, and both ends of the casing are sealed with 10mm thick steel plates.

[0093] Wall opening: (1) For openings located below the original ground level and in a narrow area where machinery cannot enter, a working pit is dug manually from the outside of the corresponding opening location before opening. A water collection pit is set in the pit to prevent rainwater from flowing back in; (2) After the preparation work is completed, the opening location is accurately marked in the room according to the design drawings; (3) The opening is manually made using an electric pick. The concrete block is broken and peeled off with the electric pick. The wall reinforcement within the sleeve area must not be cut off. After the wall reinforcement is exposed, it is cut in the middle and bent into the wall to be used as reinforcement for the opening; (4) After the wall opening is made according to the design drawings, the corresponding sleeve is placed in.

[0094] Steel ladder and railing installation: The installation of steel ladders and railings can be carried out in accordance with the specifications and requirements of existing technologies.

[0095] Step 5: Installation of equipment and facilities in the pump room renovation / expansion area includes the installation of pump bodies and pipelines. The requirements for pipeline installation are as follows:

[0096] (1) All steel pipes shall be prefabricated and laid by welding. Steel pipe welding shall be strictly inspected and accepted in accordance with the "Code for Construction and Acceptance of Water Supply and Drainage Pipeline Engineering" GB50268-97 standard. Electric welders shall be certified to work.

[0097] (2) Pipe joints are made of bevel welding;

[0098] (3) Welders must hold the corresponding qualification certificate. The type of pipe material, welding method, welding position, and validity period of the weld must all be consistent with the welder's certificate. Furthermore, they can only be employed after passing an entrance examination.

[0099] (4) The beveling of the pipe fitting weld joint is made by manual oxy-acetylene. All oxides on the cut surface should be cleaned and polished smooth.

[0100] (5) When assembling pipe fittings, the pipe sections with the smallest difference in diameter should be selected. When assembling, the inner walls should be flush. The alignment inspection should be carried out using a 300mm straightedge. The deviation of the inner wall misalignment should not be greater than 0.2 times the wall thickness and should not be greater than 2.0mm. When assembling pipe sections with different wall thicknesses, if the wall thickness is >3mm, the edge of the joint should be beveled to make the wall thickness consistent. The bevel cutting length is 4 (δ1-δ2).

[0101] (6) Before welding, inspect and clean the inside of the pipe, then inspect the bevel and remove rust, moisture, oil and dust from the bevel surface and within 50mm on both sides. After welding, the weld surface should be cleaned to remove flux, slag and spatter, and a permanent welder's code mark should be made 50mm away from the weld.

[0102] (7) Butt welding is used for pipe welding:

[0103] a. After the joint inspection is passed, spot welding is performed to fix it. Spot welding should be performed symmetrically, and the thickness of the spot welding should be consistent with the thickness of the first layer of welding.

[0104] b. For pipe fitting welds, double-sided welding should be used when the pipe diameter is greater than 800mm. For pipe diameters less than 800mm, single-sided welding should be used because it is difficult to weld the inner wall manually.

[0105] c. Welding of steel pipe joints should be carried out in the absence of sunlight and when the temperature is low. When welding closed joints, the ambient temperature should not be lower than 50℃ in winter and not higher than 300℃ in summer. Rolling joints should be used as much as possible. When welding in winter, preheating treatment should be carried out according to the ambient temperature and the thickness of the steel.

[0106] (8) Pipe fitting installation

[0107] a. The permissible deviation for flange interface parallelism should be 1.5% of the flange outer diameter, and should not exceed 2mm; the permissible deviation for bolt hole center should be 5% of the hole diameter.

[0108] b. Bolts of the same specification should be used, the installation direction should be consistent, the bolts should be tightened symmetrically, and 3-4 threads of the tightened bolt should protrude beyond the nut;

[0109] c. For the first and second rigid joints or welds adjacent to the flange interface on both sides of the pipe fitting assembly, welding should be performed after the flange bolts are tightened. However, measures should be taken to prevent damage to the flange gasket.

[0110] After the pipeline welding is completed, pipeline purging and water pressure testing, as well as pipeline disinfection and flushing operations should be carried out.

[0111] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
