Description

Technical Field

[0001] This invention relates to the field of construction methods, and in particular to an adjustable mounting bracket for a pump house and a BIM-based progressive assembly method. Background Technology

[0002] In existing technologies, traditional underground pump room construction techniques involve modifying the dimensions of pumps and pipelines upon arrival at the underground pump room, requiring cutting and welding of the original pipelines. This not only poses fire safety risks but also results in inconsistent construction quality due to the varying welding and assembly skills of on-site workers. Furthermore, the high risk of rework and uncertainty in the construction schedule contribute to the problem. This paper proposes a BIM-based recursive construction and assembly method to address these issues in existing technologies. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable mounting bracket for pump rooms and a BIM-based progressive assembly method to solve the problems of inconsistent construction quality, high rework risk, and uncertain construction period in traditional construction methods.

[0004] The technical solution of the present invention is: an adjustable mounting bracket for a pump room, comprising a connecting part and an adjusting part, wherein the adjusting part is mounted on the connecting part, and the adjusting part can move along a first direction on the connecting part to achieve adjustment in the first direction; an adjusting hole is provided at the end of the adjusting part away from the connecting part, the adjusting hole being arc-shaped, and after the adjusting hole is connected to a fixed bracket on site, adjustment in a second direction is achieved through the arc-shaped adjusting hole.

[0005] Preferably, there are two adjustment parts, which are respectively installed at both ends of the connecting part.

[0006] Preferably, the number of adjustment holes is at least two that are arranged opposite each other.

[0007] Preferably, the adjustment part is provided with a support plate inside, the support plate is fixed to the adjustment part by an adjusting threaded rod, and the adjustment radius of the support plate can be adjusted by adjusting the adjusting threaded rod.

[0008] The present invention also provides a BIM-based recursive assembly method, comprising the following steps:

[0009] S1. Detailed design, determine the relevant parameters of the equipment and materials required for processing and production, and prepare detailed requirements for the samples of the equipment and materials. Detailed design shall be carried out according to the samples provided by the equipment and material manufacturers, and BIM technology shall be used to build the model, and the corresponding detailed requirements shall be reflected in the BIM model.

[0010] S2. Production and processing: In the BIM model color recognition system, the paint color of the prefabricated pipes in different systems is kept consistent with the color settings of the electromechanical pipelines in the BIM model.

[0011] The processing and production of prefabricated equipment and pipeline modules are divided into factory prefabrication and on-site prefabrication. On-site prefabrication can be adopted for critical paths and critical nodes. The production of the prefabricated equipment and pipeline modules should establish a first-piece acceptance system. The subsequent batch production of prefabricated modules can only be carried out after the construction unit organizes relevant personnel to accept the first piece and it passes the acceptance.

[0012] S3. Delivery and transportation: All the aforementioned equipment and pipeline prefabricated modules shall be inspected and accepted upon arrival at the site, and verified and confirmed by the supervising engineer;

[0013] For the horizontal transport of large equipment and prefabricated pipeline modules in the computer room, steel rails should be built between the equipment foundations, and the horizontal transport should be carried out by special handling tools and traction by winches. The transport speed should be stable and slow during the traction process.

[0014] S4. Assembly construction: Before assembly, the equipment foundation should be pre-inspected, and installation can only proceed after it passes inspection; for large electromechanical equipment that has not been assembled, it should be positioned in advance according to the equipment layout drawing, and measures should be taken to protect the finished products; the prefabricated modules of the equipment and pipelines should be numbered in advance according to the assembly sequence of the assembly construction plan, and assembled strictly according to the numbering order, following the principle of assembling the main before the secondary, the large before the small, and the inside before the outside.

[0015] S5. Error Elimination: Error elimination is integrated throughout the entire process of detailed design, production, and assembly construction. A comprehensive error compensation system of "controlling, reducing, and eliminating errors" is adopted. The prefabricated equipment and pipeline modules include factory pipelines and pump sets. The factory pipelines and pump sets are pre-assembled in modules and will be transported to the site as a whole later. During production, adjustable mounting brackets in the pump room are used to control errors. When the factory pipelines and pump sets are installed, the pump sets are installed first, and a first fine leveling is performed on the pump sets during installation. Then the factory pipelines are installed, and after the factory pipelines are installed, a second fine leveling is performed on the pump sets to control errors.

[0016] Preferably, in step S1, when carrying out detailed design, the architectural, structural, and decorative aspects of the equipment and pipeline assembly construction area should be comprehensively considered; maintenance access should be reserved for the main equipment and prefabricated modules, and there should be a reasonable maintenance distance between them and the walls, columns, beams, ceilings, and equipment.

[0017] When conducting detailed design, based on relevant design specifications, the overall pipeline layout within the construction area, and on-site transportation and hoisting conditions, a reasonable division of equipment and pipeline prefabricated modules should be made; at the same time, the transportation and hoisting limitations of various prefabricated modules should be given special consideration.

[0018] After the equipment and pipeline prefabricated modules are grouped, a feasibility analysis and verification of the entire process of each prefabricated module should be carried out to ensure that the relevant requirements for transportation, hoisting and assembly are met.

[0019] Preferably, in step S2, before production and processing, the manufacturer should have the production process facilities and testing conditions to ensure that the prefabricated equipment and pipeline modules meet the quality requirements; before production and processing, the construction unit should organize the detailed design personnel to conduct a briefing and review of the detailed design documents with the manufacturer.

[0020] The verticality adjustment of the water pump and motor in the prefabricated module should meet the relevant technical requirements; when there are no requirements for the installation design of valves, pressure gauges, pressure transmitters and drain pipes on the prefabricated module, they should meet the requirements of the product manual.

[0021] Before leaving the factory, prefabricated equipment and pipeline modules should be uniquely coded and identified using tracking QR codes or radio frequency identification chips.

[0022] Preferably, in step S3, the site for transporting prefabricated modules, equipment, and pipelines should be flat and firm, and have drainage measures; the roads for transport vehicles to enter the construction site should meet the transportation requirements of the prefabricated modules.

[0023] The specifications, appearance, and dimensions of the prefabricated modules should be inspected. The packaging should be intact, and the surface should be free of scratches and damage.

[0024] Before horizontal transportation, the orientation of the starting point and the transportation route should be reasonably planned according to the final position and orientation of the equipment and pipeline prefabricated modules; the transportation route should not turn multiple times, and the orientation of the equipment and pipeline prefabricated modules should not be adjusted during transportation.

[0025] Preferably, in step S4, for assembly construction areas where prefabricated modules are arranged in rows or densely, ground assembly, overall lifting or jacking assembly methods should be adopted if conditions permit.

[0026] The assembly of prefabricated hanger modules should meet the relevant requirements of each electromechanical system. Key parts should be appropriately reinforced, and fixed supports should be installed in necessary parts.

[0027] Preferably, in step S5, the operational errors caused by human error during the production and assembly of complete sets of equipment are effectively controlled through refined modeling, direct export of blueprints from BIM, and automated processing technology; through highly integrated modular design, uncontrollable errors under the pure pipe section prefabrication method are transformed into controllable errors, and controllable errors are transformed into critical errors, thereby achieving error elimination and reduction.

[0028] Compared with the prior art, the advantages of the present invention are:

[0029] (1) The present invention provides an adjustable installation bracket for pump room, which eliminates additional stress, makes the risk controllable, and avoids the problem that if workers do not install according to the construction specifications, the factory pipeline will have unconventional stress points, which will cause the factory pipeline to deform and the welded points on the pipeline to leak easily.

[0030] (2) In this invention, when the factory pipeline is installed, fixed supports and temporary supports are used. The fixed supports are used to fix the factory pipeline, and the temporary supports are used to adjust the position deviation of the factory pipeline. The adjustment method of the temporary supports is to adjust according to stress detection and construction error.

[0031] (3) The temporary support in this application can be adjusted in length in the first direction and in circumferential direction in the second direction, which can effectively control and eliminate various errors generated during pipeline construction.

[0032] (4) By simulating the construction effect, construction plan and construction details of the construction project, this invention can reduce or avoid most of the errors in the design process, efficiently optimize the construction plan, convey the construction procedure requirements, and carry out construction quality inspection in real time during the construction process, thus avoiding inefficiency, waste and rework to a large extent.

[0033] (5) Compared with traditional construction methods, this invention reduces the number of installation personnel due to the use of standard parts assembly. There is no need to invest in construction equipment such as electric welding machines, drilling machines, cutting machines, and oxygen and acetylene devices on site, which can effectively save construction costs. The new construction method does not require hot work in the pump room, so the safety factor is high. The construction speed is fast, and almost all of them are flange connections, so the installation accuracy is high, the quality is good, and the operating noise is low.

[0034] (6) Since the present invention does not require on-site welding, on-site grinding and rust removal, or on-site painting, it will not generate multiple pollutions such as arc light, smoke, and odor, thus protecting the on-site construction environment. Attached Figure Description

[0038] Figure 3 This is a schematic diagram of the adjusting part of an adjustable mounting bracket for a pump room according to this application;

[0039] Figure 4 This is a flowchart of a BIM-based recursive assembly method according to this application.

[0040] The components are: 1. Connecting part, 2. Adjusting part, 21. Adjusting hole, 22. Support plate, 23. Adjusting threaded rod. Detailed Implementation

[0041] The present invention will be further described in detail below with reference to specific embodiments:

[0042] In the description of the invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention.

[0043] like Figure 1-3 As shown, an adjustable mounting bracket for a pump room includes a connecting part 1 and an adjusting part 2. The adjusting part 2 is mounted on the connecting part 1 and can move along a first direction on the connecting part 1 to achieve adjustment in the first direction. In this embodiment, the first direction is the horizontal direction. Both the connecting part 1 and the adjusting part 2 are provided with mounting holes. The mounting holes on the adjusting part 2 are mounting grooves. The mounting position of the mounting groove can move back and forth on the connecting part 1. After moving to the designated position, it is fixed by bolts to achieve horizontal movement of the adjusting part 2 on the connecting part 1. In this embodiment, there are two adjusting parts 2. During the installation of the pipe supported by the adjusting bracket, the adjusting parts 2 at both ends can be adjusted in the horizontal direction.

[0044] An adjustment hole 21 is provided at the end of the adjustment unit 2 furthest from the connecting part 1. The adjustment hole 21 is arc-shaped. After the adjustment hole 21 is connected to the fixed support on site, adjustment in a second direction is achieved through the arc-shaped adjustment hole 21. The second direction is the circumferential direction of the pipeline. When the adjustment unit 2 is connected to the fixed support on the construction site, the arc-shaped adjustment hole 21 is aligned with the support on the construction site. The arc-shaped adjustment hole 21 has its own assembly allowance, so even if an error occurred in the previous pipeline assembly, normal assembly can be achieved in this station. In this embodiment, there are 4 adjustment holes 21, and the 4 adjustment holes 21 are arranged symmetrically in pairs.

[0045] The adjusting part 2 is also equipped with a support plate 22, which is fixed to the adjusting part 2 by an adjusting threaded rod 23. The adjusting radius of the support plate 22 can be adjusted by adjusting the threaded rod 23. The support plate 22 is arc-shaped to match the shape of the pipe. The adjusting threaded rod 23 is installed on the outside of the support plate 22 by a threaded connection. The adjusting threaded rod 23 is threadedly connected to the adjusting part 2. By adjusting the length of the threaded rod 23, different types of pipes can be matched, and the pipe is fixed in the adjusting bracket.

[0046] like Figure 4 As shown, a BIM-based recursive construction assembly method includes: S1. Detailed design, determining the relevant parameters (specifications, models, and technologies) of the equipment and materials required for processing and production, and compiling detailed requirements for equipment and materials samples. Detailed design is carried out according to the samples provided by the equipment and materials manufacturers, and BIM technology is used to build the model, reflecting the corresponding detailed requirements in the BIM model.

[0047] In step S1, during the detailed design process, the architectural, structural, and decorative aspects of the equipment and pipeline assembly construction area should be comprehensively considered. Maintenance access must be reserved for major equipment and prefabricated modules, with reasonable maintenance distances from walls, columns, beams, ceilings, and between equipment. Based on relevant design specifications, and considering the comprehensive pipeline layout within the construction area and on-site transportation and hoisting conditions, a reasonable division of equipment and pipeline prefabricated modules should be made. Simultaneously, the transportation and hoisting limitations of various prefabricated modules should be carefully considered. After grouping the equipment and pipeline prefabricated modules, a feasibility analysis and verification of the entire implementation process for each prefabricated module should be conducted, ensuring compliance with relevant transportation, hoisting, and assembly requirements. Detailed design drawings include equipment foundation and drainage ditch layout drawings, electromechanical equipment layout drawings, comprehensive electromechanical pipeline layout drawings, and processing and assembly drawings of equipment and pipeline prefabricated modules.

[0048] S2. Production and processing: In the BIM model color recognition system, the paint color of prefabricated pipes in different systems is kept consistent with the color settings of electromechanical pipelines in the BIM model; the processing and production of equipment and pipeline prefabricated modules are divided into factory prefabrication and on-site prefabrication. On-site prefabrication can be adopted for critical paths and critical nodes; the production of equipment and pipeline prefabricated modules should establish a first-piece acceptance system. The construction unit should organize relevant personnel to accept the first piece before the subsequent batch production of prefabricated modules can begin.

[0049] In step S2, before production and processing, the manufacturer should have the production process facilities and testing conditions to ensure that the prefabricated equipment and pipeline modules meet the quality requirements; before production and processing, the construction unit should organize the detailed design personnel to conduct a briefing and review of the detailed design documents with the manufacturer; the adjustment and measurement of the verticality of the water pump and motor in the prefabricated module should meet the relevant technical requirements; if there are no requirements for the installation design of valves, pressure gauges, pressure transmitters, and drain pipes on the prefabricated module, they should meet the requirements of the product manual; before leaving the factory, the prefabricated equipment and pipeline modules should be uniquely coded and identified by tracking QR codes or radio frequency identification chips.

[0050] The first-piece acceptance system refers to the requirement that when a prefabricated module with a complex structure or a new type of prefabricated module is produced for the first time or after a long interval, the manufacturer must conduct a first-piece acceptance together with the construction, design, construction, and supervision units to confirm whether the production process of the batch of prefabricated modules is reasonable and whether the quality is guaranteed. Mass production can only begin after the joint acceptance is qualified.

[0051] In step S2, the prefabricated equipment and pipeline modules include factory pipelines and pump sets. These factory pipelines and pump sets are pre-assembled in modules and will be transported to the site as a whole. Later, the factory pipelines and pump sets are installed in modules, almost entirely using flange connections, resulting in high installation precision and quality. During installation, the pump sets are installed first, and a first leveling process is performed on them. Then, the factory pipelines are installed. After the factory pipelines are installed, a second leveling process is performed on the pump sets to prevent damage to the pump sets caused by vibrations from uneven installation. Fixed supports and temporary supports are used during factory pipeline installation. Fixed supports are used to secure the factory pipelines, while temporary supports are used to adjust for positional deviations. The adjustment of temporary supports is based on stress testing and construction errors. Without temporary supports, the risks are uncontrollable. If workers do not install according to construction specifications, unconventional stress points may be created, leading to deformation of the factory pipelines over time, and leaks may occur at weak weld points.

[0052] S3. Delivery and transportation: All equipment and pipeline prefabricated modules shall be inspected and accepted upon arrival at the site and verified by the supervising engineer. For the horizontal transportation of large equipment and pipeline prefabricated modules in the machine room, steel rails shall be built between the equipment foundations and the horizontal transportation shall be carried out by special handling tools and traction by winches. The transportation speed shall be stable and slow during the traction process.

[0053] In step S3, the on-site transport roads, equipment and pipeline prefabricated module stacking area should be flat and firm, with drainage measures; the roads for transport vehicles to enter the construction site should meet the transport requirements of the prefabricated modules; the specifications, appearance and dimensions of the prefabricated modules should be inspected, and the packaging should be intact with no scratches or damage on the surface;

[0054] Before horizontal transportation, the orientation of the starting point and the transportation route should be reasonably planned according to the final position and orientation of the equipment and pipeline prefabricated modules; the transportation route should not turn multiple times, and the orientation of the equipment and pipeline prefabricated modules should not be adjusted during transportation.

[0055] S4. Assembly Construction: Before assembly, the equipment foundation should be pre-inspected, and installation can only proceed after it passes inspection. The foundation concrete strength, coordinates, elevation, dimensions, and bolt hole positions must meet the design or manufacturer's technical requirements. The surface should be flat and of good appearance quality, free from defects such as honeycomb, pitting, cracks, holes, and exposed reinforcement. For large electromechanical equipment that has not yet been assembled, it should be positioned in advance according to the equipment layout drawing, and measures should be taken to protect the finished product. Prefabricated modules of equipment and pipelines should be numbered in advance according to the assembly sequence of the assembly construction plan, and assembly should be carried out strictly in accordance with the numbering sequence, following the principle of assembling from main to secondary, from large to small, and from inside to outside.

[0056] In step S4, for assembly construction areas where prefabricated modules are arranged in rows or densely, ground assembly, overall lifting, or jacking assembly methods should be adopted where conditions permit; the assembly of prefabricated hanger modules should meet the relevant requirements of each electromechanical system, key parts should be appropriately reinforced, and fixed supports should be set up in necessary parts; after the equipment and pipeline prefabricated modules are assembled and positioned, temporary supports should be set up or temporary fixing measures should be taken in a timely manner.

[0057] S5. Error Elimination: Error elimination is integrated throughout the entire process of detailed design, production, and assembly construction. A comprehensive error compensation system of "controlling, reducing, and eliminating errors" is adopted. Prefabricated equipment and pipeline modules include factory pipelines and pump sets. The factory pipelines and pump sets are pre-assembled in modules and will be transported to the site as a whole later. During production, adjustable installation brackets in the pump room are used to control errors. When the factory pipelines and pump sets are installed, the pump sets are installed first, and a first fine leveling is performed on the pump sets during installation. Then the factory pipelines are installed. After the factory pipelines are installed, a second fine leveling is performed on the pump sets to control errors. During the installation of factory pipelines, fixed brackets and temporary brackets are used. Fixed brackets are used to fix the factory pipelines, and temporary brackets are used to adjust the positional deviation of the factory pipelines. The adjustment method of the temporary brackets is based on stress detection and construction errors.

[0058] In step S5, through refined modeling, direct export of blueprints from BIM, and automated processing technology, operational errors caused by human error during the production and assembly of complete sets of equipment are effectively controlled. Through highly integrated modular design, uncontrollable errors under the pure pipe section prefabrication method are transformed into controllable errors, and controllable errors are transformed into critical errors, thereby achieving error elimination and reduction.

[0059] The construction adopts a progressive construction method of control section + compensation section. The complete pump set assembly module is used as the control section, and the electromechanical pipeline assembly module connected to it is assembled progressively according to the planned route. The compensation section is set outside the machine room or between two assembly lines, and the error of the compensation section is eliminated by on-site prefabrication.

[0060] In summary, this construction assembly method is based on a refined Building Information Model (BIM). During the design phase, various electromechanical and piping units are scientifically and rationally divided and combined. Each unit is manufactured industrially rather than processed on-site, combined with modular overall delivery, to achieve efficient and precise modular assembly construction on the construction site. This is further supplemented by specific installation and error control technologies to achieve rapid and accurate overall installation, ultimately resulting in higher efficiency, better construction quality, and lower construction safety risks throughout the entire construction process.

[0061] The above embodiments are merely illustrative of the technical concept and features of the present invention, intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and should not be construed as limiting the scope of protection of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of the present invention is defined by the appended claims rather than the foregoing description, and thus all changes falling within the meaning and scope of the equivalents of the claims are intended to be included within the present invention.
