Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated construction, and in particular to a method for improving the construction quality of a prefabricated enclosure wall of a converter station. Background Art

[0002] At present, my country has initially formed a high-quality development system framework for the construction industry, and the level of construction industrialization, digitization, and intelligence has been greatly improved. my country's economy is developing rapidly and society is constantly progressing. In the implementation of sustainable development in the domestic power industry, the construction of power transmission and transformation projects has transformed and upgraded from traditional models to green construction methods. Prefabricated structures have entered a rapid development stage, aiming to form a mature green construction model for power transmission and transformation projects and build new green buildings that are safe, high-quality, green, low-carbon, economically efficient, resource-saving, and environmentally harmonious.

[0003] Under the premise that my country's power construction has been vigorously developed, substation and converter station projects are still using the traditional prefabricated wall construction mode, that is, manually recording and transmitting information. Because the information transmission is not timely and accurate, the information island phenomenon is serious, which makes the construction difficult, and the traditional two-dimensional drawings cannot fully display the prefabricated structure information data. In this regard, people need to repeatedly modify and review according to the actual construction situation, resulting in the following problems:

[0004] (1) The design drawings are not accurate and comprehensive, which seriously affects the progress of the wall construction;

[0005] (2) Manually operated machinery for the installation of prefabricated fences cannot effectively guarantee the installation accuracy and quality;

[0006] (3) As prefabricated fences are assembled from prefabricated components, if a component needs to be repaired or replaced, the entire fence may need to be dismantled, which may make the repair process more complicated and expensive;

[0007] Therefore, the research and application of BIM technology was carried out in the construction of the prefabricated fence project of the converter station, aiming to improve the overall installation quality of the prefabricated fence. It also played a good leading and guiding role in the future demonstration of new technology application and laid a good foundation for the promotion of new technology application. Summary of the invention

[0008] The invention discloses a method for improving the construction quality of an assembled enclosure wall of a converter station, aiming to solve the technical problems in the background technology.

[0009] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] A method for improving the construction quality of a converter station assembled enclosure comprises the following steps:

[0011] Step 1: Construction of BIM model. Designers build a targeted BIM prefabricated component library for prefabricated fences according to the appearance and functional requirements of the fences, and input various specifications of various prefabricated components into the BIM platform to build a BIM parametric component family library. Each specification of prefabricated components in the BIM parametric component family library is assigned a unique identifier. The overall prefabricated design plan and component requirements are obtained, and the unique identifier of the component is identified according to the required component specifications, and the components required for the overall design plan are counted.

[0012] During the construction of the prefabricated BIM component library for prefabricated fences, designers can further supplement the prefabricated component library according to the actual requirements of the fence project. In addition, if the prefabricated component manufacturer is unable to produce the components in the prefabricated component library, the manufacturer can ask the designer to make appropriate adjustments to the requirements in the prefabricated component library.

[0013] At the same time, according to the constructed BIM prefabricated component library of prefabricated fences, multiple prefabricated components are combined, and combined with the actual structural plan, multiple prefabricated components are combined into different components, and different components are combined into different structures to construct the BIM structure library of prefabricated fences.

[0014] Step 2: Site layout. The construction progress of prefabricated building projects is deeply affected by the rationality of site layout. Therefore, when laying out the site, it is necessary to reasonably layout the material discharge area and the construction area to ensure the personal safety of the construction workers and thus ensure the smooth progress of the construction;

[0015] By applying BIM technology, the corresponding construction site model can be constructed. At the same time, the layout of the prefabricated component yard can be optimized and the crane can be laid out at the same time. When constructing the component construction site model, it is necessary to formulate multiple different site layout plans on the BIM platform, and select the optimal site layout plan through comparative analysis;

[0016] Step 3: Simulate the construction process. In order to smoothly install prefabricated components and avoid secondary handling of prefabricated components, the three-dimensional construction of the case project is simulated by applying BIM technology;

[0017] Step 4: Construction of prefabricated wall panels;

[0018] First, the preparation before construction, the prefabricated components are transported to the construction site, and on-site inspection is carried out, and then the qualified prefabricated components are stacked at the construction site;

[0019] In the above process, the application of BIM technology and RFID technology can track and control prefabricated components. During the delivery of prefabricated components, the RFID chips installed in the transport vehicles are scanned, and the delivery information of prefabricated components can be uploaded to the collaborative management platform, which is convenient for construction management personnel to timely understand and grasp the transportation status of prefabricated component vehicles; in order to ensure the effectiveness and authenticity of prefabricated component information, the arrival information of prefabricated components should be entered into the RFID chip;

[0020] Third, to hoist the prefabricated wall panels, it is necessary to adjust the spacing between the columns of the prefabricated wall in advance to ensure the accuracy of the size of the prefabricated wall panels. Then, the information stored in the RFID chip is used to scan the QR code in the prefabricated wall to quickly obtain the location, size and model of the prefabricated wall panels, so as to accurately hoist the prefabricated wall panels. After hoisting the prefabricated wall panels to the designated location, the prefabricated wall panels can be installed.

[0021] Fourth, step five: inspection and acceptance, conduct systematic inspection and acceptance of the assembled converter station fence.

[0022] In a preferred solution, in step one, by applying BIM technology to construct a BIM prefabricated component library for prefabricated walls, the dimensions of the walls can be determined more accurately, the setting of the dimensions of the walls can be effectively optimized, and based on this, a corresponding reasonable wall design solution can be proposed, thereby effectively avoiding the occurrence of unreasonable structural dimensions.

[0023] By applying BIM technology, the pipeline model of the converter station can be constructed, so that the influence of the pipeline on the assembly can be perfectly avoided during the assembly process. Therefore, the position, elevation and layout of the pipeline within the wall can be reasonably adjusted and optimized to facilitate the installation and layout of the pipeline.

[0024] In a preferred solution, in step 1, the purpose of constructing a BIM structure library for prefabricated walls is to demonstrate the complex parts and key nodes in the assembly process of prefabricated components and ensure the feasibility of prefabricated component assembly.

[0025] In a preferred solution, in step 2, when constructing the construction site model through BIM technology, it is necessary to consider the problem that the prefabricated wall has multiple working surfaces and needs to be constructed simultaneously, as well as the problem that 2-3 cranes need to be configured to operate simultaneously during the construction process, so as to avoid the impact of unreasonable arrangement of the lifting and stacking of prefabricated components on the construction progress of the prefabricated wall.

[0026] By establishing a three-dimensional model of the construction site, we can more intuitively observe and analyze the layout of the construction site, quickly discover existing problems, and formulate corresponding effective solutions to further optimize and improve the layout of the site.

[0027] In a preferred solution, in step 4, after the transport vehicle enters the construction site, the construction management personnel can promptly notify relevant personnel to come to the site to inspect and accept the quality of the prefabricated components, and stack the prefabricated components that meet the acceptance standards at the specified locations according to the construction site regulations.

[0028] In a preferred solution, in step 4, during the process of tracking and controlling the prefabricated components, a QR code matching the RFID chip needs to be installed on the surface of the prefabricated components to facilitate rapid identification of the prefabricated components.

[0029] In a preferred solution, in step 4, the tacit understanding between the signalman and the crane driver is an important factor affecting the hoisting speed of the prefabricated wall panels. Therefore, it is necessary to select a signalman and a crane driver with a high tacit understanding.

[0030] In a preferred solution, in step 4, during the process of hoisting the prefabricated wall panels, the installation status of these wall panels can be intuitively tracked and displayed in the three-dimensional model, and when the installation is not in place, the position of the wall columns can be adjusted in time.

[0031] As can be seen from the above, the method for improving the construction quality of the assembled wall of a converter station provided by the present invention can find the existing problems by applying BIM technology to simulate the construction, so as to solve these problems in time. In addition, it can effectively improve the construction efficiency and quality, and avoid rework due to the construction personnel's misunderstanding of the two-dimensional drawings. Secondly, by applying BIM technology, the position, elevation and layout of the pipelines in the wall can be reasonably adjusted and optimized at the construction nodes, which is convenient for the installation and arrangement of pipelines. In the process of the assembled wall construction of the converter station, it has the advantages of increasing the reliability of the wall installation, improving the construction quality and speed, reducing the construction period, reducing rework and repair, and improving the construction efficiency, thereby reducing the project cost. At the same time, it further forms a complete set of assembled wall BIM application technology, which plays a good guiding role in the promotion and application of internal or enterprise standards. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Reference Figure 1 A method for improving the construction quality of a converter station assembled wall comprises the following steps:

[0035] Step 1: Construction of BIM model. Designers build a targeted BIM prefabricated component library for assembled fences based on the appearance and functional requirements of the fences.

[0036] Specifically, by applying BIM technology to construct a BIM prefabricated component library for prefabricated fences, the fence dimensions can be determined more accurately, the setting of the fence dimensions can be effectively optimized, and based on this, a corresponding reasonable fence design plan can be proposed, thereby effectively avoiding the occurrence of unreasonable structural dimensions.

[0037] Input various specifications of prefabricated components into the BIM platform, build a BIM parametric component family library, assign a unique identifier to each specification of prefabricated components in the BIM parametric component family library, obtain the overall prefabricated design plan and component requirements, identify the unique identifier of the component according to the required component specifications, and count the components required for the overall design plan;

[0038] During the construction of the prefabricated BIM component library for prefabricated fences, designers can further supplement the prefabricated component library according to the actual requirements of the fence project. In addition, if the prefabricated component manufacturer is unable to produce the components in the prefabricated component library, the manufacturer can ask the designer to make appropriate adjustments to the requirements in the prefabricated component library.

[0039] At the same time, according to the constructed BIM prefabricated component library of prefabricated fences, multiple prefabricated components are combined, and combined with the actual structural plan, multiple prefabricated components are combined into different components, and different components are combined into different structures to construct the BIM structure library of prefabricated fences.

[0040] Specifically, the purpose of building a BIM structure library for prefabricated fences is to demonstrate the complex parts and key nodes in the assembly process of prefabricated components and ensure the feasibility of prefabricated component assembly.

[0041] In the above steps, by applying BIM technology, the size of the fence can be determined more accurately, the setting of the fence size can be effectively optimized, and based on this, a corresponding reasonable fence design plan can be proposed, thereby effectively avoiding the occurrence of unreasonable structural dimensions; at the same time, by applying BIM technology, the pipeline model of the converter station can be constructed, so that the influence of the pipeline on the assembly can be perfectly avoided during the assembly process, so that the position, elevation and layout of the pipeline in the fence can be reasonably adjusted and optimized, which is convenient for the installation and layout of the pipeline.

[0042] At the same time, more detailed design is needed, which includes component reinforcement adjustment, reserved and embedded design of electromechanical pipelines and processes, avoidance of reserved and embedded openings, component processing at material joints, component processing at facade corners, running-in of cast-in-place metal cover plates and the location of air-conditioning condensate pipes, etc., which can more accurately ensure the normal progress of construction and further improve construction efficiency.

[0043] Step 2: Site layout. The construction progress of prefabricated building projects is deeply affected by the rationality of site layout. Therefore, when laying out the site, it is necessary to reasonably layout the material discharge area and the construction area to ensure the personal safety of the construction workers and thus ensure the smooth progress of the construction;

[0044] By applying BIM technology, the corresponding construction site model can be constructed. At the same time, the layout of the prefabricated component yard can be optimized and the crane can be laid out at the same time. When constructing the component construction site model, it is necessary to formulate multiple different site layout plans on the BIM platform, and select the optimal site layout plan through comparative analysis;

[0045] Specifically, when constructing a construction site model through BIM technology, it is necessary to consider the problem that the prefabricated fence has multiple working surfaces and needs to be constructed simultaneously, as well as the problem that 2-3 cranes need to be configured to operate simultaneously during the construction process, so as to avoid the impact of unreasonable arrangement of the lifting and stacking of prefabricated components on the construction progress of the prefabricated fence.

[0046] Through the above steps, a three-dimensional model of the construction site is established, which can more intuitively observe and analyze the layout of the construction site, facilitate rapid discovery of existing problems, and formulate corresponding effective solutions to further optimize and improve the layout of the site.

[0047] Step 3: Simulate the construction process. In order to smoothly install prefabricated components and avoid secondary transportation of prefabricated components, the three-dimensional construction of the case project is simulated by applying BIM technology. At the same time, the construction personnel need to be briefed on the three-dimensional technology to intuitively show the special construction nodes to the construction personnel.

[0048] Through the above steps, since there are many complex construction nodes in the construction process, which are all the key and difficult points of construction, by applying BIM technology to simulate construction, problems can be discovered and solved in time. In addition, in order to improve construction efficiency and quality, rework can be avoided due to construction personnel's lack of understanding of two-dimensional drawings.

[0049] Step 4: Construction of prefabricated wall panels;

[0050] First, the preparation before construction, the prefabricated components are transported to the construction site, and on-site inspection is carried out, and then the qualified prefabricated components are stacked at the construction site;

[0051] In the above process, the application of BIM technology and RFID technology can track and control prefabricated components. During the delivery of prefabricated components, the RFID chips installed in the transport vehicles are scanned, and the delivery information of prefabricated components can be uploaded to the collaborative management platform, which is convenient for construction management personnel to timely understand and grasp the transportation status of prefabricated component vehicles; in order to ensure the effectiveness and authenticity of prefabricated component information, the arrival information of prefabricated components should be entered into the RFID chip;

[0052] Specifically, after the transport vehicles enter the construction site, the construction management personnel can promptly notify relevant personnel to come to the site to inspect and accept the quality of the prefabricated components, and stack the prefabricated components that meet the acceptance standards at the specified locations according to the construction site regulations.

[0053] Specifically, in the process of tracking and controlling prefabricated components, it is necessary to install a QR code matching the RFID chip on the surface of the prefabricated components to facilitate rapid identification of the prefabricated components.

[0054] Second, when hoisting prefabricated wall panels, it is necessary to adjust the spacing between the prefabricated wall columns in advance to ensure the accuracy of the size of the prefabricated wall panels;

[0055] Among them, for the hoisting speed of prefabricated wall panels, the tacit understanding between the signalman and the crane driver is an important influencing factor. Therefore, it is necessary to select signalmen and crane drivers with higher tacit understanding.

[0056] The information stored in the RFID chip is then used to scan the QR code in the prefabricated wall to quickly obtain the location, size and model of the prefabricated wall panels, so that the prefabricated wall panels can be accurately hoisted. After the prefabricated wall panels are hoisted to the designated location, the installation of the prefabricated wall panels can begin.

[0057] In the process of hoisting prefabricated wall panels, the installation status of these wall panels can be intuitively tracked and displayed in the three-dimensional model. When the installation is not in place, the position of the wall columns can be adjusted in time.

[0058] Step 5: Inspection and acceptance: conduct systematic inspection and acceptance of the assembled converter station fence.

[0059] To sum up, the present invention provides a method for improving the construction quality of the prefabricated wall of a converter station by applying BIM technology to simulate construction, so that problems existing therein can be discovered and solved in time. In addition, the construction efficiency and quality can be effectively improved to avoid rework caused by construction personnel not understanding the two-dimensional drawings. Secondly, by applying BIM technology at construction nodes, the position, elevation and layout of pipelines in the wall can be reasonably adjusted and optimized to facilitate the installation and arrangement of pipelines. Therefore, in the process of constructing the prefabricated wall of the converter station, it has the advantages of increasing the reliability of wall installation, improving construction quality and speed, reducing construction period, reducing rework and repair, and improving construction efficiency to reduce project costs. At the same time, a complete set of BIM application technology for prefabricated walls is further formed, which plays a good guiding role in the promotion and application of internal or enterprise standards.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
