TECHNICAL FIELD

[0001] The present application relates to the technical field of fabricated construction, in particular to a method for improving the construction quality of a fabricated fence of a converter station. BACKGROUND

[0002] At present, China has initially formed a high-quality development system framework for the construction industry, and the level of construction industrialization, digitization and intelligentization has been greatly improved. China's economy is developing rapidly, and society is progressing. In the implementation of sustainable development of the domestic power industry, the construction of power transmission and transformation projects is transforming from the traditional mode to the green construction mode. The fabricated structure has entered a stage of rapid development, aiming to form a mature green construction mode for power transmission and transformation projects, and to build new green buildings that are safe, high-quality, green, low-carbon, economic, efficient, resource-saving and environmentally harmonious.

[0003] Under the premise that the construction of electric power in China has been vigorously developed, the construction of substations and converter stations still uses the traditional fabricated fence construction mode, that is, information is recorded and transmitted by manual operation. Because the information transmission is not timely and accurate, and the information island phenomenon is serious, it leads to great construction difficulty, and the traditional two-dimensional drawings cannot fully display the fabricated structure information data. For this reason, people need to repeatedly modify and review according to the actual construction situation, which leads to the following problems:

[0004] (1) The design drawing information is not accurate and comprehensive, which seriously affects the fence construction process;

[0005] (2) Manual operation of machinery for fabricated fence installation cannot effectively guarantee the installation precision and quality;

[0006] (3) Since the fabricated fence is assembled by 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 complex and expensive;

[0007] Therefore, the application of BIM technology in the fabricated fence construction of the converter station is carried out, aiming to improve the overall installation quality of the fabricated fence, play a good leading role in the demonstration of new technology application in the future, and lay a good foundation for the promotion of new technology application. SUMMARY

[0009] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme:

[0010] A method for improving the construction quality of a fabricated fence of a converter station, comprising the following steps:

[0011] Step one: construction of BIM model, the designer constructs the prefabricated wall BIM component library with pertinence according to the appearance requirements, functional requirements and so on, and inputs various specifications of prefabricated components in BIM platform, constructs BIM parameterized component family library, and gives each specification of prefabricated components in BIM parameterized component family library a unique identifier, and obtains the overall design scheme and component demand, identifies the unique identifier of the required component according to the required component specification, and counts the components required by the overall design scheme;

[0012] In the process of constructing the prefabricated wall BIM component library, the designer further supplements the prefabricated component library according to the actual requirements of the wall project, in addition, if the prefabricated component manufacturer cannot produce the components in the prefabricated component library, the manufacturer requires the designer to adjust the requirements in the prefabricated component library appropriately;

[0013] At the same time, according to the constructed prefabricated wall BIM component library, a plurality of prefabricated components are combined, and a plurality of prefabricated components are combined into different components, and different components are combined into different structures, and a prefabricated wall BIM structure library is constructed.

[0014] Step two: site layout, the construction progress of prefabricated building engineering is deeply affected by the rationality of site layout, so when the site is laid out, the layup area and construction area need to be reasonably laid out to ensure the personal safety of construction personnel, so as to ensure the smooth progress of construction;

[0015] By applying BIM technology, the corresponding construction site model is constructed, the layout of the prefabricated component yard is optimized, and the crane is laid out at the same time. When constructing the component construction site model, a plurality of different site layout schemes need to be formulated in the BIM platform, and the optimal site layout scheme is selected through comparison and analysis;

[0016] Step three: simulation of construction process, in order to successfully install prefabricated components and avoid secondary handling of prefabricated components, BIM technology is applied to simulate the three-dimensional construction of the case project;

[0017] Step four: construction of prefabricated wallboard;

[0018] First, the prefabricated components produced and made are transported to the construction site, and on-site inspection is carried out, and then the prefabricated components that pass the inspection are stacked on the construction site;

[0019] In the above process, the BIM technology and the RFID technology are applied to track and control the prefabricated components, the RFID chip installed in the transport vehicle is scanned in the process of the prefabricated components leaving the factory, and the leaving factory information of the prefabricated components is uploaded to the collaborative management platform, so that the construction management personnel can timely understand and master the transport situation of the prefabricated component vehicle; in order to ensure the effectiveness and authenticity of the prefabricated component information, the arrival information of the prefabricated component should be recorded in the RFID chip;

[0020] Secondly, the prefabricated wallboard needs to be hoisted, the spacing between the assembled fence columns needs to be adjusted in advance to ensure the accuracy of the size of the assembled wallboard, then the information stored in the RFID chip is applied to scan the two-dimensional code in the assembled wallboard, the position, size and model of the prefabricated wallboard are quickly obtained, and the prefabricated wallboard is accurately hoisted, after the prefabricated wallboard is hoisted to the specified position, the prefabricated wallboard is installed;

[0021] Thirdly, step five: inspection and acceptance, the assembled converter station fence is systematically detected and accepted.

[0023] By applying the 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, and thus the position, elevation and layout of the pipeline in the fence can be reasonably adjusted and optimized, facilitating the installation and arrangement of the pipeline.

[0024] In a preferred scheme, in step one, the purpose of constructing the BIM structure library of the assembled fence is to demonstrate the complex parts and key nodes in the prefabricated component assembly process, and to ensure the feasibility of the prefabricated component assembly.

[0025] In a preferred scheme, in step two, when the construction site model is constructed by the BIM technology, the problem of multiple working faces of the assembled fence that need to be constructed at the same time, and the problem of 2-3 cranes that need to be configured to operate at the same time during the construction process need to be considered, so as to avoid the influence of unreasonable arrangement of the hoisting and stacking of the prefabricated components on the construction progress of the assembled fence.

[0026] By establishing the three-dimensional model of the construction site, the layout of the construction site can be more intuitively observed and analyzed, the problems existing therein can be quickly found out, and corresponding effective solutions can be developed, so as to further optimize and improve the layout of the site.

[0027] In a preferred scheme, in step four, when the transport vehicle enters the construction site, the construction manager timely informs the relevant personnel to check and accept the quality of the prefabricated component on site, and according to the provisions of the construction site, the prefabricated component that meets the acceptance standard is stacked at the specified position.

[0028] In a preferred scheme, in step four, in the process of tracking and controlling the prefabricated component, a two-dimensional code matched with the RFID chip needs to be installed on the surface of the prefabricated component, so as to facilitate quick identification of the prefabricated component.

[0029] In a preferred scheme, in step four, for the hoisting speed of the prefabricated wall panel, the tacit understanding between the signal worker and the crane driver is an important influencing factor, therefore, the signal worker and the crane driver with high tacit understanding need to be selected.

[0033] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all embodiments.

[0034] REFERENCE Figure 1 A construction quality improvement method for a prefabricated fence of a converter station, comprising the following steps:

[0035] Step one: construction of BIM model, the designer constructs the prefabricated component library of assembly wall BIM according to the appearance requirements, functional requirements, etc.

[0036] Specifically, by applying BIM technology to construct the prefabricated component library of assembly wall BIM, the size of the wall can be determined more accurately, the size of the wall can be effectively optimized, and the corresponding reasonable wall design scheme can be proposed as an important basis, so as to effectively avoid the unreasonable structure size.

[0037] And input various specifications of various prefabricated components in the BIM platform, construct the BIM parameterized component family library, and give each specification of the prefabricated component in the BIM parameterized component family library a unique identifier, and obtain the overall design scheme and component requirements, identify the unique identifier of the required component according to the required component specification, and count the required components of the overall design scheme;

[0038] During the construction of the prefabricated component library of assembly wall BIM, the designer further supplements the prefabricated component library according to the actual requirements of the wall project. In addition, if the prefabricated component manufacturer cannot produce the components in the prefabricated component library, the manufacturer requires the designer to adjust the requirements in the prefabricated component library appropriately.

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

[0040] Specifically, the purpose of constructing the BIM structure library of assembly wall is to demonstrate the complex parts and key nodes in the prefabricated component assembly process and ensure the feasibility of prefabricated component assembly.

[0041] In the above steps, by applying BIM technology, the size of the wall can be determined more accurately, the size of the wall can be effectively optimized, and the corresponding reasonable wall design scheme can be proposed as an important basis, so as to effectively avoid the unreasonable structure size; 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 wall can be reasonably adjusted and optimized, and the pipeline can be installed and arranged.

[0042] At the same time, more detailed design is needed, including component reinforcement adjustment, mechanical and electrical pipeline and process pre-embedded design, pre-embedded hole avoidance, material transfer component treatment, facade corner component treatment, cast-in-place layer break-in metal cover plate and air conditioning condensate pipe position, etc., which can more accurately ensure the normal progress of construction and further improve the efficiency of construction.

[0043] Step two: site layout, the construction progress of prefabricated building engineering is deeply affected by the rationality of site layout, so when the site is laid out, the material placing area and the construction area need to be reasonably laid out to ensure the personal safety of construction personnel and ensure the smooth progress of construction;

[0044] By applying BIM technology, the corresponding construction site model is constructed, the layout of the prefabricated component yard is optimized, and the crane is laid out at the same time. When constructing the component construction site model, multiple different site layout schemes need to be developed in the BIM platform, and the optimal site layout scheme is selected through comparison and analysis.

[0045] Specifically, when constructing the construction site model through BIM technology, it needs to consider the problem of multiple prefabricated enclosure wall working surfaces that need to be constructed at the same time, as well as the problem of configuring 2-3 cranes to operate simultaneously during the construction process, in order to avoid the impact of unreasonable arrangement of prefabricated component hoisting and stacking on the construction progress of prefabricated enclosure walls.

[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 the rapid discovery of problems, and develop corresponding effective solutions to further optimize and improve the layout of the site.

[0047] Step three: simulate the construction process, in order to smoothly install prefabricated components and avoid secondary handling of prefabricated components, a three-dimensional construction of the case engineering is simulated through the application of BIM technology; at the same time, three-dimensional technical disclosure is needed for construction personnel, so as to intuitively present special construction nodes to construction personnel.

[0048] Through the above steps, there are many complex construction nodes in the construction process, which are the key points of construction. By applying BIM technology to simulate construction, problems can be found and solved in time, and in addition, to improve construction efficiency and construction quality, avoid rework due to construction personnel's misunderstanding of two-dimensional drawings.

[0049] Step four: construction of prefabricated wall panels;

[0050] First, the prefabricated components produced and made in the early stage of construction are transported to the construction site and inspected on site, and then the prefabricated components that pass the inspection are stacked on the construction site;

[0051] In the above process, the BIM technology and RFID technology are applied to track and control the prefabricated components. In the process of leaving the factory, the RFID chip installed in the transport vehicle is scanned, and the leaving factory information of the prefabricated component is uploaded to the collaborative management platform, so that the construction management personnel can timely understand and master the transportation situation of the prefabricated component vehicle. In order to ensure the effectiveness and authenticity of the prefabricated component information, the arrival information of the prefabricated component should be recorded in the RFID chip.

[0052] Specifically, after the transport vehicle enters the construction site, the construction management personnel timely notify the relevant personnel to check and accept the quality of the prefabricated component on site. According to the regulations of the construction site, the prefabricated components that meet the acceptance standards are stacked at the specified position.

[0053] Specifically, in the process of tracking and controlling the prefabricated components, a two-dimensional code matched with the RFID chip needs to be installed on the surface of the prefabricated component, so as to facilitate the rapid identification of the prefabricated component.

[0054] Secondly, the prefabricated wallboard needs to be hoisted, and the spacing between the prefabricated wallboard and the assembled wall column needs to be adjusted in advance to ensure the accuracy of the size of the prefabricated wallboard.

[0055] Among them, the tacit understanding between the signal worker and the crane driver is an important factor affecting the hoisting speed of the prefabricated wallboard, so it is necessary to select a signal worker and a crane driver with high tacit understanding.

[0056] Then the information stored in the RFID chip is scanned to obtain the position, size and model of the prefabricated wallboard, so as to accurately hoist the prefabricated wallboard. After the prefabricated wallboard is hoisted to the specified position, the prefabricated wallboard is installed.

[0057] Among them, in the process of hoisting the prefabricated wallboard, the installation situation of the wallboard can be intuitively tracked and displayed in the three-dimensional model. When the installation is not in place, the position of the wall column can be adjusted in time.

[0058] Step five: inspection and acceptance, system detection and acceptance of the assembled converter station fence.

[0059] In summary, the construction quality improvement method for the assembled fence of the converter station provided by the application can simulate construction by applying BIM technology, find problems existing therein, and solve these problems in time. In addition, the construction efficiency and construction quality are effectively improved, and the rework phenomenon caused by the fact that the construction personnel do not understand the two-dimensional drawings is avoided. Furthermore, the position, elevation, and layout of the pipeline in the fence are reasonably adjusted and optimized by applying BIM technology, which is convenient for installing and arranging the pipeline. Thus, the assembled fence construction of the converter station has the advantages of increasing the installation reliability of the fence, improving the construction quality and speed, reducing the construction period, reducing the rework and repair, improving the construction benefit, and reducing the engineering cost. Meanwhile, a complete BIM application technology for the assembled fence is further formed, which plays a good guiding role in promoting the application of the internal or enterprise standard.

[0060] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacements or changes to the technical solutions and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
