Description

Technical Field

[0001] This invention belongs to the field of building pipeline construction technology, and specifically relates to a method for arranging pipelines in exhibition hall trenches. Background Technology

[0002] The pipeline layout of an exhibition hall / exhibition trench refers to the organization and arrangement of pipes and lines within the trench during its design and construction. Pipeline layout includes the laying and routing of drainage, water supply, and gas pipelines; line layout includes the installation of power lines, telephone lines, and network cables. Due to the large number and complexity of pipes and lines, the pipeline layout must adhere to specific planning and design principles to ensure the building's safety, efficiency, energy conservation, and aesthetics.

[0003] Exhibition halls often have multiple lines installed within their display areas to accommodate various devices and enhance the presentation of exhibits. However, in environments with numerous devices and complex wiring, electromagnetic interactions between lines can lead to interference. For example, when multiple power and signal lines are arranged in parallel, their electromagnetic signals may interfere with each other, affecting signal quality or causing interference. This can result in problems such as disrupting the normal operation of electronic devices, causing data transmission errors, and leading to circuit malfunctions.

[0004] In summary, the existing pipeline layout and construction process lacks effective measures to reduce electromagnetic interference, making it difficult to ensure the normal operation of exhibition hall equipment and the safety of visitors. Summary of the Invention

[0005] In view of this, the present invention proposes a method for arranging pipelines in exhibition hall trenches, which can solve the problem of lack of effective measures to reduce electromagnetic interference during pipeline arrangement, making it difficult to ensure the normal operation of exhibition hall equipment and the safety of visitors.

[0006] This invention is implemented as follows:

[0007] This invention provides a method for arranging pipelines in exhibition hall trenches, comprising the following steps:

[0008] S10: Compile the design drawings of the exhibition hall and exhibition trenches, and understand the structural form and design requirements of the exhibition trenches;

[0009] S20: Create the civil engineering model, electromechanical model, and pipeline model of the exhibition hall and trench as a BIM model;

[0010] S30: Perform collision detection on the civil engineering model, the electromechanical model, and the pipeline model to obtain the optimal layout scheme of the trenching pipeline and output the construction drawing of the trenching pipeline;

[0011] S40: Arrange and construct the trench pipelines in accordance with the construction drawings;

[0012] S50: Conduct quality acceptance testing, checking whether the construction of the trench pipeline is in accordance with the construction... Figure 1 To.

[0013] The technical advantages of the exhibition hall trench pipeline layout method provided by this invention are as follows: This exhibition hall trench pipeline layout method uses collision detection on the BIM model, placing the electromechanical model, pipeline model, and civil engineering model in the same workspace for automated detection to identify conflicts between the various models. This helps to identify conflicts and errors in the pipeline layout design process in advance, improving design quality. In addition, by making local adjustments and optimizations to the BIM model, combined with the actual site conditions, the effect of the internal pipeline layout of the exhibition hall trench can be checked more accurately, ensuring that there are no conflicts between the various components. This effectively avoids repeated construction and adjustments in subsequent projects, thereby reducing project costs and improving construction efficiency; it also improves construction quality, reduces the error rate of pipeline construction, and reduces safety issues during pipeline use.

[0014] Based on the above technical solution, the exhibition hall trench pipeline layout method of the present invention can be further improved as follows:

[0015] Specifically, step S40 includes the following steps:

[0016] Step 1: Based on the construction drawings, install pipes in the trench, install wiring racks at the cable routing locations, and install cable reels at both ends of the wiring racks;

[0017] The second step is to arrange the cables in the wiring rack and wrap the loose cables at both ends around the winding spool.

[0018] The third step is to use a cable fixing tool to position the multiple parallel cables.

[0019] Fourth step: Based on the on-site layout and construction of the exhibition hall and exhibition trenches, summarize the parts that are more difficult to construct on-site, and make local adjustments and optimizations to the BIM model.

[0020] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: By setting up cable trays, the cables and pipes laid in the trench can be organized in an orderly manner, which is equivalent to covering the outside of the cables with a metal shielding layer to suppress the propagation of electromagnetic waves and thus prevent electromagnetic interference from affecting the signal. This can avoid electromagnetic interactions between cables when there are many cables and the current inside the cables is large, which would affect the signal quality or cause interference. By setting up cable reels, loose cables can be wound around the reels, which can tighten the cables, making them neat and beautiful, and preventing tearing, breaking, and sticking between wires with different directions, which could lead to leakage and electric shock. By setting up cable fixing tools, the cables of each electromechanical device can be fixed together individually, making it easy for staff to identify them. This can effectively prevent the cables from being tangled and difficult to distinguish when there are many and messy cables, which is beneficial for later inspection and maintenance operations.

[0021] Furthermore, the wiring rack includes a U-shaped receiving compartment with an opening at the top covered by a removable cover plate. Multiple partition plates are arranged side by side on the bottom wall of the receiving compartment, dividing the interior of the receiving compartment into multiple receiving slots. The receiving slots are used for arranging pipes or cables, and the top of the receiving slots is covered by a removable cover plate. The winding reels are located at both ends of the receiving compartment for storing excessively long cables.

[0022] The housing, isolation plate, and cover are all made of metal. When the cover is closed, a metal shielding layer is formed inside each housing slot. The metal's isolation effect improves the cable's shielding performance, reduces the cable's inductance and leakage impedance, and reduces the coupling of interference signals. The height of the housing sidewall is greater than the height of the isolation plate, and the depth of each housing slot is slightly greater than the cable's diameter. This allows the metal shielding layer to be as close as possible to the cable's surface, reducing the gap or air between the metal isolation screen and the wire, thus achieving the best protective effect.

[0023] Furthermore, the winding reel includes a first component and a second component. The first component and the second component cooperate with each other and form a winding cylinder for winding cables at the cooperation part. The outer end faces of the first component and the second component are respectively provided with an outwardly extending first extension and a second extension. The inner sides of the first extension and the second extension are respectively provided with a first connecting cylinder and a second connecting cylinder. The inner side of the first extension has a plurality of first buckles extending axially, and the inner side of the second extension has a plurality of second buckles extending axially. The first buckles and the second buckles are staggered in the circumferential direction. The first buckles and the second buckles are interlocked to realize the assembly connection of the first component and the second component. The outer peripheral surfaces of the first connecting cylinder and the second connecting cylinder after the first component and the second component are assembled form the groove bottom of the winding cylinder.

[0024] Both the first and second components are made of polycarbonate, which is fireproof and electrical-resistant, and keeps the winding reel insulated. The flexible first extension and first connecting cylinder act as a limit when the components are turned outward, preventing the cable from coming loose from the winding reel. When the components are turned inward, they cover the wound cable, preventing the cable from being exposed. By setting the first and second components to be plug-in, the cable can be wrapped around the first and second clips before the two parts are installed, avoiding pulling the cable and causing the arrangement to shift. At the same time, it also has the characteristics of simple structure and easy disassembly and assembly, which facilitates the smooth construction operation.

[0025] Furthermore, both the first extension and the second extension are made of flexible material and are trumpet-shaped with a large outer diameter and a small inner diameter; when the first extension and the second extension are turned outward, the tubing wound on the winding drum is exposed; when the first extension and the second extension are turned inward, the tubing wound on the winding drum is covered.

[0026] Furthermore, the first component has a first connecting hole in the middle along the axial direction, and the second component has a second connecting hole in the middle along the axial direction. Hollow connecting members are provided in the first connecting hole and the second connecting hole, and the connecting members connect the first component and the second component together. The two ends of the connecting members are adsorbed onto the side walls on both sides of the receiving groove by suction cups.

[0027] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting the connector, the hollow first component and the second component can be supported, and the plastic first component and the second component can be prevented from deforming when subjected to the heat generated by the current; at the same time, the suction cups set at both ends of the connector can be stably attached to the two side walls of the receiving chamber, so that the position of the connector is fixed, thereby fixing the position of the first component and the second component. The winding reel is fixed at both ends of the receiving chamber, and the cable inside the receiving chamber is tightened.

[0028] Furthermore, the connector includes a male connector and a female connector. The male connector extends into the first connecting hole from the outside to the inside, and the female connector extends into the second connecting hole from the outside to the inside. An inwardly extending fastening portion is provided on the inner side wall of the end of the male connector that extends into the first connecting hole, and a snap-fit ​​groove adapted to the fastening portion is provided on the outer side wall of the end of the female connector that extends into the second connecting hole. While the fastening portion and the snap-fit ​​groove are fastened and fixed together, the side wall of the male connector presses against the first component, and the side wall of the female connector presses against the second component.

[0029] The beneficial effects of adopting the above-mentioned improved scheme are as follows: by setting up a male plug and a female plug, and using the fastening and fixing between the two, the connector is stably kept as a whole. It has the characteristics of simple structure, easy installation and disassembly, and can provide support for the first component and the second component, while also providing positioning for the first component and the second component.

[0030] Furthermore, the line fixing tool includes a fixed handle, a movable handle, and an outer bracket. The fixed handle has a hollow structure, and the movable handle is disposed inside the fixed handle and hinged to the fixed handle. A fixed head is provided at the top of the fixed handle, and a locking plate that slides up and down is provided on the front side of the fixed head. A limiting groove is formed in the middle of the locking plate, and a first pressing groove is provided at the bottom of the locking plate. A movable head that adapts to the limiting groove is provided at the top of the movable handle, and the movable head is fitted into the limiting groove. The outer bracket is fixedly connected to the fixed head by screws. An L-shaped adjustment groove is provided on the side wall of the outer bracket for adjusting the connection position between the outer bracket and the fixed head. A fixed platform is provided on the front side of the outer bracket, and a second pressing groove is provided on the top of the fixed platform, with the second pressing groove located directly below the first pressing groove.

[0031] The first and second pressure grooves are symmetrically shaped waves. The first pressure groove has the same shape as the bottom of the locking plate, and the second pressure groove has the same shape as the top of the fixing platform. When the locking plate and the fixing platform are aligned, multiple parallel, nearly circular holes are formed. Each hole can accommodate one cable, which is beneficial for fixing multiple cables side by side at the same time, making the cables neat and orderly. By hinged the fixed handle and the movable handle, and the length of the handle part of the fixed handle and the movable handle is greater than the length of the front side of the hinge part, the fixed handle and the movable handle form a force-saving lever structure, making the operation more convenient and effortless. A pin slot is also provided at the rear of the fixing platform, which can store multiple locking pins to avoid the tedious operation of repeatedly adding them.

[0032] Furthermore, the outer support is also provided with a nail-continuing device, which includes a connecting plate. The connecting plate is fixedly installed at the tail of the outer support. A guide shaft is fixedly connected to the connecting plate. A compression spring is sleeved on the outside of the guide shaft. One end of the compression spring is fixedly connected to the connecting plate, and the other end of the compression spring is fixedly connected to the push nail block.

[0033] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting up a continuous nail device, the locking nails can be pushed into the fixed platform one by one, which can effectively improve the operating efficiency.

[0034] Furthermore, a return spring is also provided inside the fixing head, with the bottom end of the return spring fixedly connected to the top wall inside the fixing head, and the top end of the fixing head fixedly disposed at the front end of the movable handle.

[0035] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a return spring, a spring-loaded structure is formed at the front end of the fixed handle and the movable handle. When the user releases the fixed handle and the movable handle, the front end of the fixed handle and the movable handle can automatically return to its original position under the elastic force of the return spring, thereby improving the continuity of operation.

[0036] Compared with existing technologies, the beneficial effects of the exhibition hall trench pipeline layout method provided by this invention are as follows: During the design phase, this method performs collision detection on the BIM model, placing the electromechanical model, pipeline model, and civil engineering model in the same workspace for automated detection to identify conflicts between models. This facilitates the early identification of conflicts and errors in the pipeline layout design process, improving design quality. During the construction phase, by setting up pipeline racks, the cables and pipes laid in the trench can be organized in an orderly manner, essentially covering the cables with a metal shielding layer to suppress the propagation of electromagnetic waves, thereby hindering the impact of electromagnetic interference on signals. This avoids electromagnetic interactions between cables, especially when there are many cables and high currents within them, which could affect signal quality or cause interference. Furthermore, by setting up winding reels, loose cables can be organized... Cables are wound around a reel, ensuring a taut and neat appearance. This prevents tearing, breakage, and sticking between wires traveling in different directions, which could lead to leakage or electric shock, thus improving safety. Cable securing tools allow for individual fixing of cables for each piece of equipment, facilitating identification by staff and preventing tangled cables from becoming difficult to distinguish when there are many cables. This also benefits future inspection and maintenance. Furthermore, by adjusting and optimizing the BIM model during construction, combined with actual site conditions, the layout of internal pipelines in the exhibition hall and trenches can be better guaranteed, ensuring no conflicts between components. This effectively avoids repeated construction and adjustments in subsequent projects, thereby reducing project costs and improving construction efficiency. It also improves construction quality, reduces the error rate in pipeline construction, and minimizes safety issues during pipeline use. Attached Figure Description

[0053] like Figure 1 The diagram shows a flowchart of a method for arranging pipelines in exhibition hall trenches provided by the present invention, which specifically includes the following steps:

[0054] S10: Compile the design drawings of the exhibition hall and exhibition trenches, and understand the structural form and design requirements of the exhibition trenches;

[0055] S20: Create the civil engineering model, mechanical and electrical model, and pipeline model of the exhibition hall and exhibition trenches as a BIM model;

[0056] S30: Perform collision detection on the civil engineering model, electromechanical model, and pipeline model to obtain the optimal layout scheme of the trench pipeline and output the construction drawings of the trench pipeline.

[0057] S40: Arrange and construct the trench pipelines in accordance with the construction drawings;

[0058] S50: Conduct quality acceptance testing, checking whether the trenching and pipeline construction is in accordance with the construction plan. Figure 1 To.

[0059] Specifically, step S20 involves creating the electromechanical model, pipeline model, and civil engineering model of the exhibition hall trench.

[0060] The BIM model was created using Magicad and Revit. Revit was used to create the civil engineering model, incorporating design information about the exhibition hall's base area, building entrance, and facade to design the site and establish the civil engineering model. This model represents the appearance and performance of the exhibition hall and its surroundings, and is further divided into major engineering components such as the facade and interior space. Magicad was used to create the MEP (Mechanical, Electrical, and Plumbing) model and pipeline model to connect the various MEP models. Each MEP pipeline and equipment was grouped using different colors according to detailed requirements for location and elevation.

[0061] The specific steps for collision detection of the civil engineering model, mechanical and electrical model, and pipeline model in step S30 are as follows:

[0062] Using Magicad's built-in collision detection function, collision detection is performed between the electromechanical model and the civil engineering model, between the electromechanical model and the pipeline model, and between the civil engineering model and the pipeline model. Hard or soft collision is performed according to design requirements, and a collision information report is generated. At the same time, Magicad marks all collision points with clear symbols based on the collision information.

[0063] The specific steps for quality acceptance in step S50 are as follows:

[0064] Based on the design requirements of the trench, the construction drawings of the trench pipelines, and the current national construction and acceptance standards, an on-site inspection was conducted to verify the layout and elevation of the pipeline structure to ensure compliance with construction requirements. Figure 1 The pipelines and equipment were tested to ensure that the structure was robust and met the design requirements.

[0065] In the above technical solution, step S40 specifically includes the following steps:

[0066] Step 1: Based on the construction drawings, install pipes in the trench, install cable tray 1 at the cable routing location, and install cable reels 2 at both ends of cable tray 1.

[0067] The second step is to arrange the cables in the wiring rack 1 and wrap the loose cables at both ends around the winding spool 2.

[0068] The third step is to use cable securing tools to position multiple parallel cables.

[0069] The fourth step is to combine the on-site layout and construction of the exhibition hall and exhibition trenches, summarize the parts that are more difficult to construct on-site, and make local adjustments and optimizations to the BIM model.

[0070] The specific steps for making local adjustments to the BIM model, focusing on areas that are difficult to construct on-site, are as follows:

[0071] During the layout and construction process, we continuously analyze the incomplete locations in the BIM model and the difficult parts of on-site construction, communicate in a timely manner to find the best construction plan, and make local adjustments to optimize the BIM model based on actual problems.

[0072] like Figure 2-3 As shown, further, in the above technical solution, the wiring rack 1 includes a U-shaped receiving compartment 10. The top of the receiving compartment 10 is an opening, and the opening is covered with a removable cover plate 13. Multiple isolation plates 11 are arranged side by side on the bottom wall of the receiving compartment 10. The isolation plates 11 divide the interior of the receiving compartment 10 into multiple receiving slots 12. The receiving slots 12 are used to arrange pipes or cables. The top of the receiving slots 12 is covered with a removable cover plate 13. The winding reels 2 are arranged at both ends of the receiving compartment 10 for storing excessively long cables.

[0073] When using it, determine the frequency range of protection based on the requirements of the environment and equipment, select appropriate shielding metal materials for the containment chamber 10, isolation plate 11 and cover plate 13, and ground the containment chamber 10 to prevent leakage of interference signals.

[0074] like Figure 4-5As shown, further, in the above technical solution, the winding reel 2 includes a first component 20 and a second component 21. The first component 20 and the second component 21 cooperate with each other, and a winding cylinder 22 for winding cables is formed at the cooperation part. The outer end faces of the first component 20 and the second component 21 are respectively provided with outwardly extending first extension 201 and second extension 211. The inner surfaces of the first extension 201 and the second extension 211 are respectively provided with a first connecting cylinder 202 and a second connecting cylinder 212. Multiple first buckles 203 extend axially from the inner side of an extension 201, and multiple second buckles 213 extend axially from the inner side of a second extension 211. The first buckles 203 and the second buckles 213 are staggered in the circumferential direction. The first buckles 203 and the second buckles 213 are interlocked to achieve the assembly connection of the first component 20 and the second component 21. The outer circumferential surfaces of the first connecting cylinder 202 and the second connecting cylinder 212 after the first component 20 and the second component 21 are assembled form the groove bottom of the winding cylinder 22.

[0075] Furthermore, in the above technical solution, the first extension 201 and the second extension 211 are both made of flexible material and are trumpet-shaped with a large outer diameter and a small inner diameter; when the first extension 201 and the second extension 211 are turned outward, the tubing wound on the winding drum 22 is exposed; when the first extension 201 and the second extension 211 are turned inward, the tubing wound on the winding drum 22 is covered.

[0076] Furthermore, in the above technical solution, the first component 20 has a first connecting hole 204 axially formed in the middle of the first component 20, and the second component 21 has a second connecting hole 214 axially formed in the middle of the second component 21. The first connecting hole 204 and the second connecting hole 214 are provided with hollow connecting members 23, which connect the first component 20 and the second component 21 together. The two ends of the connecting members 23 are adsorbed onto the side walls on both sides of the receiving groove 12 by suction cups.

[0077] Furthermore, in the above technical solution, the connector 23 includes a male connector 231 and a female connector 232. The male connector 231 is inserted into the first connecting hole 204 from the outside to the inside, and the female connector 232 is inserted into the second connecting hole 214 from the outside to the inside. The inner side wall of the end of the male connector 231 that extends into the first connecting hole 204 is provided with an inwardly extending fastening part, and the outer side wall of the end of the female connector 232 that extends into the second connecting hole 214 is provided with a snap-fit ​​groove adapted to the fastening part. While the fastening part and the snap-fit ​​groove are fastened and fixed to each other, the side wall of the male connector 231 presses against the first component 20, and the side wall of the female connector 232 presses against the second component 21.

[0078] In use, the construction worker first wraps the loose cable around the outer circumference of the first clip 203 or the second clip 213 to straighten the cable. Then, the first component 20 and the second component 21 are plugged in and connected. When assembling the first component 20 and the second component 21, the first clip 203 is aligned with the slot on the end wall of the second connecting cylinder 212, and the second clip 213 is aligned with the slot on the end wall of the first connecting cylinder 202. The outer sides of the first component 20 and the second component 21 are then pressed firmly to ensure that the cable is straight. The male connector 231 is then inserted into the first connection hole 204, and the female connector 232 is inserted into the second connection hole 214. The snap-fit ​​part on the male connector 231 is embedded into the snap-fit ​​groove provided on the outer side wall of the female connector 232, so that the male connector 231 and the female connector 232 are fixedly connected, providing support for the inner walls of the first component 20 and the second component 21. Finally, the suction cups provided at both ends of the connector 23 are attached to the two side walls of the receiving chamber 10 to fix the position of the winding reel 2.

[0079] like Figure 6-8 As shown, further, in the above technical solution, the line fixing tool includes a fixed handle 30, a movable handle 31, and an outer bracket 32. The fixed handle 30 has a hollow structure, and the movable handle 31 is disposed inside the fixed handle 30, and the movable handle 31 is hinged to the fixed handle 30. A fixing head 301 is provided on the top of the fixed handle 30, and a locking plate 302 that slides up and down is provided on the front side of the fixing head 301. A limit groove 3021 is provided in the middle of the locking plate 302, and a first pressing groove 3022 is provided at the bottom of the locking plate 302. The movable handle... The top of the hand 31 is provided with a movable head 312 that is adapted to the limiting slide groove 3021. The movable head 312 is fitted inside the limiting slide groove 3021. The outer bracket 32 ​​is fixedly connected to the fixed head 301 by screws. The side wall of the outer bracket 32 ​​is provided with an L-shaped adjustment groove 323 for adjusting the connection position between the outer bracket 32 ​​and the fixed head 301. The front side of the outer bracket 32 ​​is provided with a fixed platform 321. The top of the fixed platform 321 is provided with a second pressing groove 3211. The second pressing groove 3211 is located directly below the first pressing groove 3022.

[0080] In use, the cables are first separated. The rear cables are placed in the cable placement slots 3212 on both sides of the fixed platform 321, while the front cables are placed side by side in the wavy groove of the fixed platform 321. When the user grips the handles of the fixed handle 30 and the movable handle 31 and applies force inward, the movable handle 31 can rotate around the pivot due to the hinge between the fixed handle 30 and the movable handle 31. When the handle of the movable handle 31 moves toward the fixed handle 30, the movable head 312 moves downward, causing the locking plate 302 to move downward. With the support of the fixed platform 321, the bottom of the locking plate 302 and the top of the fixed platform 321 press against the locking pins. The locking pins deform and are fitted onto the outside of the multiple parallel cables, thus fixing the multiple cables. The locking pin is a U-shaped long strip of metal wire with the opening facing upwards. During installation, its bottom is placed in the second pressure groove 3211 on the top of the fixing platform 321.
