Description

Technical Field

[0001] The present invention relates to the technical field of building engineering, and in particular to a BIM-based nuclear power plant hole plugging engineering management system and a management method thereof. Background Art

[0002] Holes are reserved for certain works (such as pipelines across rooms) or for the convenience of construction during the construction of nuclear power plants. They are a series of works that need to be sealed after all pipelines and equipment of the nuclear power plant are installed and before the nuclear power plant is delivered to the owner. Such as window holes, door holes, etc.

[0003] There are a large number of mechanical holes in the nuclear island building, 8BWX building, BGZ integrated corridor and non-nuclear BOP holes of the nuclear power plant. According to the hole plugging list of each building and the relevant clarification change documents, all mechanical holes need to be plugged except for the holes that are clearly not plugged in the relevant documents. For holes with mechanical plugging function requirements, their plugging must meet the corresponding fire prevention, watertightness, airtightness, displacement, decontamination, chemical erosion and radiation protection requirements. For holes with no functional requirements and only decontamination, chemical erosion and displacement requirements (excluding movable cover holes, stair holes, floor drain holes, door holes and secondary concrete holes), plugging is required as required. The holes are unequally distributed in different nuclear island buildings. Generally, there are about tens of thousands of holes that need to be plugged in a nuclear island, and the plugging methods of various holes are different. It is very cumbersome to judge the plugging method of each hole, and the workload of plugging work and subsequent statistics is very large. Currently, all work is done manually based on Excel (including the preparation of various statistical tables, especially the work of "specifying the 'blocking method' according to the 'blocking requirements'"), which is time-consuming, labor-intensive and prone to errors. Summary of the invention

[0004] The purpose of the present invention is to provide a nuclear power plant hole plugging project management system and management method based on BIM, so as to achieve the management of the hole plugging project through information means, especially to achieve the quick generation of "plugging methods" to improve the efficiency and accuracy of the hole plugging work in nuclear power plants. The purpose of the present invention is achieved through the following technical solutions:

[0005] A BIM-based nuclear power plant hole plugging engineering management system, including a hole list execution status tracking table generation unit and a BIM model association unit;

[0006] The BIM model association unit associates the generated hole list execution status tracking table with the nuclear power plant BIM model, so that the BIM model automatically reads the data on the completion status of each hole plugging work in each link from the management system;

[0007] The execution tracking table generation unit includes a list receiving module, a resource matching module, a completion reporting module and a statistical analysis module;

[0008] The list receiving module is used to input the hole plugging execution list and / or hole information change list made according to the hole information derived from the BIM model of the designer, and automatically save it to the hole list execution status tracking table, the hole information includes: hole type information, hole-related item attribute information, hole plugging requirement information, biological shielding requirement information and fire blocking requirement information; in the hole information, the hole type information includes the main function of the hole, the hole shape and the remarks on whether to plug; the hole-related item attribute information includes: the type of factory building where the hole is located, the floor, the thickness of the wall or board, the hole size, the name of the associated item, the item type, the item size, the axial displacement and the radial displacement; the hole plugging requirement information includes the hole plugging requirement Y and the hole plugging requirement N, the hole plugging requirement Y represents a functional hole, and the hole plugging requirement N represents a non-functional hole; the biological shielding requirement information includes the biological shielding requirement of N and the biological shielding requirement of a specific value, wherein the biological shielding requirement of N means that it does not have a biological shielding function;

[0009] The resource matching module includes three submodules: a technical solution matching submodule, a human resource matching submodule and a material and equipment matching submodule; the technical solution matching submodule determines the plugging method of each hole according to the hole information; the human resource matching submodule inputs the personnel work division information determined according to the hole plugging method; the material and equipment matching submodule inputs the material and equipment information required for each hole determined according to the hole plugging method; the information of the three submodules of the resource matching module is merged and saved in the hole list execution tracking table;

[0010] The determination of the hole blocking method comprises the following steps:

[0011] S1. Screen out holes that do not need to be blocked according to hole type information;

[0012] S2. Confirm the material of the hole to be plugged through multi-level step-by-step query: query the hole plugging requirement information through the first level, and confirm that the hole plugging requirement is N or Y; enter different second-level queries according to different first-level query results, and the second-level query items are the types of related items. After determining the plugging material according to different second-level query results, exit or continue to enter the third-level query; the third-level query items include the type of plant where the hole is located, the shape of the hole, and the biological shielding requirements of the hole. After determining the plugging material according to different third-level query results, exit or continue to enter the fourth-level query; the fourth-level query items include item type, hole size and displacement; after determining the plugging material according to the fourth-level query results, exit or enter the fifth-level query; the fifth-level query item is displacement, and after entering the fifth-level query, determine the plugging material or exit;

[0013] S3. Determine the thickness of the plugging material according to the plugging material;

[0014] S4. Determine whether to set up a heat insulation layer according to the fire blocking requirement information;

[0015] S5, combining the confirmation results of steps S2 to S4 to generate a blocking method for each hole;

[0016] The completion inspection module is used to input the quality inspection and acceptance results and the completion plan change data, and save them to the hole list execution tracking table;

[0017] The statistical analysis module is used to automatically extract update information from the list receiving module, resource matching module and completion reporting module and save it to the hole list execution tracking table, and to perform statistics on the completion status, project quantity, labor quantity and material consumption of the hole plugging project.

[0018] In one embodiment, the holes that do not need to be blocked in step S1 include: edge-sealed steel frame holes, manholes, transfer air vents, windows, rain gutters, overflow holes, elevator paging box reserved holes, elevator shelf beam reserved holes, pressure relief holes, transfer air vent holes, and holes noted as not to be blocked.

[0019] In one implementation, the specific process of step S2 is:

[0020] 2-1 Perform a first-level query to query the hole plugging requirement information. The hole plugging requirement is N or Y;

[0021] 2-2 If the hole plugging requirement is N, enter the secondary query to query the item type information:

[0022] If the item type information is "-, / , None", concrete plugging is used; otherwise, enter the third-level query to query the plant type; the plant type is BRX or non-BRX; BRX means reactor plant;

[0023] If the plant is BRX, perform a level 4 query to query the item type information. If the item type is an air duct, use concrete to seal it. Otherwise, enter the level 5 query to query the displacement information. If the axial displacement or radial displacement is ≤20mm, use JSF-L fireproof silicone foam to seal it. If it does not meet the axial displacement or radial displacement ≤20mm, exit the query.

[0024] If the plant is not a BRX, a four-level query is performed to query the hole size information: if the single-side size of the hole is greater than 400mm, the hole is blocked with silicon cloth and filler; otherwise, silicon cloth is used to block the hole;

[0025] 2-3 If the hole plugging requirement is Y, enter the secondary query to query the item type information:

[0026] If the item type is an air duct, it is sealed with concrete; if the item type is a pipe, a three-level query is performed to query the shape information of the hole. If it is a square hole, it is sealed with a combination of concrete and special materials. If it is not a square hole, the query is exited; If the item type is neither an air duct nor a pipe, a three-level query is performed to query the biological shielding requirement information of the hole. The biological shielding requirement is N or a specific value;

[0027] If the biological shielding requirement is N, enter the fourth-level query to find the displacement information. If the axial displacement or radial displacement is ≤20mm, use JSF-L fireproof silicone foam for plugging; if 20mm<axial displacement or radial displacement ≤40mm, use JSE-RF flexible silicone elastomer for plugging; if the axial displacement or radial displacement is >40mm, exit the query;

[0028] If the biological shielding requirement is a specific value (such as 200, 500), enter the fourth-level query to find the displacement information. If the axial displacement or radial displacement is ≤5mm, use JSE-H high-density silicone rubber for sealing. If 5mm < axial displacement or radial displacement ≤40mm, use JSE-RF flexible silicone elastomer for sealing. If the axial displacement or radial displacement is >40mm, exit the query.

[0029] In one embodiment, in step S3: if the sealing material is JSF-L fireproof silicone foam, the fixed sealing thickness is 200 mm; if the sealing material is JSE-H high-density silicone rubber or JSE-RF flexible silicone elastomer, the sealing thickness is the same as the required thickness for biological shielding; if the sealing material is concrete, the sealing thickness is the same as the wall or floor thickness.

[0030] The present invention also provides a nuclear power plant hole plugging project management method, which is based on the BIM-based nuclear power plant hole plugging project management system and includes the following steps:

[0031] 1) The design unit marks the hole information of each hole in the BIM model;

[0032] 2) The design unit exports the hole information involved in the hole plugging work to be performed during the next work period from the BIM model and sends it to the construction unit. The construction unit prepares a hole plugging execution order and enters it into the management system;

[0033] 3) The construction unit performs the hole plugging work according to the hole plugging execution sheet, and saves the completion status of each link of the hole plugging work into the hole list execution status tracking table in the management system; the hole plugging work of each link includes: receiving the list, converting the hole plugging method scheme according to the hole information, matching the resources of manpower, materials and equipment according to the hole plugging method, and on-site construction status and quality acceptance;

[0034] 4) The BIM model automatically reads the data on the completion status of each hole plugging work in each link from the management system. The target object in the nuclear power plant BIM model responds to clicks to display the real-time update content of the hole list execution status tracking table associated with the target area indicated by the target object; management personnel can view it at any time.

[0035] The beneficial effects of the present invention are:

[0036] The present invention combines the nuclear power plant hole plugging project management system with BIM, so that the construction party can receive the execution information, plugging requirements, and hole information of the plugging in a timely manner, and convert the "plugging method" through quick query, quickly match manpower and material resources, and upload acceptance statistics and other information in a timely manner; so that the design party can query the construction progress and understand the specific construction situation at any time, which is convenient for monitoring the construction progress and timely proposing information corrections. Therefore, the present invention realizes the management of the entire life cycle of the hole plugging project through information technology, and realizes the real-time and dynamic display of the information of each working status of each hole in the nuclear power project in the BIM model, so as to improve the efficiency and accuracy of the hole plugging work in the nuclear power plant.

[0037] The present invention simplifies the tedious work of determining the hole plugging method through a multi-level query method by designing a technical solution matching sub-module in the resource matching module. The query method is specially set for the nuclear island plant of the existing nuclear power plant, has strong versatility, and is convenient and fast. Through program settings, it can achieve "automatic, one-click, and fast generation of plugging methods according to hole plugging requirements", which saves a lot of computing power and time and improves construction efficiency.

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Figure 2 This is a flow chart of the method for determining hole plugging in Example 1. DETAILED DESCRIPTION

[0041] Example 1

[0042] A BIM-based nuclear power plant hole plugging engineering management system, including a hole list execution status tracking table generation unit and a BIM model association unit;

[0043] The BIM model association unit associates the generated hole list execution status tracking table with the database of the nuclear power plant BIM model, and through automatic data capture, the BIM model automatically reads the data on the completion status of each hole plugging work in each link from the management system;

[0044] The hole list execution status tracking table generation unit includes a list receiving module, a resource matching module, a completion inspection module and a statistical analysis module. In this embodiment, the hole list execution status tracking table generation process is as follows: Figure 1 shown.

[0045] The list receiving module is used to input the hole plugging execution list and / or hole information change list made according to the hole information in the hole list derived from the BIM model of the designer, and automatically save it to the hole list execution status tracking table, wherein the hole information includes: hole type information, hole-related item attribute information, hole plugging requirement information, biological shielding requirement information and fire blocking requirement information; In the hole information, the hole type information includes the main function of the hole, the hole shape and the remarks on whether to block it; the hole-related item attribute information includes the type of factory building where the hole is located, the floor, the thickness of the wall or board, the hole size, the name of the related item, the item type, the item size, the axial displacement and the radial displacement; the hole blocking requirement information includes the hole blocking requirement Y and the hole blocking requirement N, the hole blocking requirement Y indicates a functional hole, and the hole blocking requirement N indicates a non-functional hole; the biological shielding requirement information includes the biological shielding requirement of N and the biological shielding requirement of a specific value, wherein the biological shielding requirement of N indicates that it does not have a biological shielding function;

[0046] The resource matching module includes three submodules: a technical solution matching submodule, a human resource matching submodule and a material and equipment matching submodule; the technical solution matching submodule determines the plugging method of each hole according to the hole information; the human resource matching submodule inputs the personnel work division information determined according to the hole plugging method; the material and equipment matching submodule inputs the material and equipment information required for each hole determined according to the hole plugging method; the information of the three submodules of the resource matching module is merged and saved in the hole list execution tracking table;

[0047] The determination of the hole blocking method comprises the following steps:

[0048] S1. Screen out holes that do not need to be blocked according to hole type information: including: edge-sealed steel frame holes, manholes, transfer vents, windows, rain gutters, overflow holes, reserved holes for elevator call boxes, reserved holes for elevator shelf beams, pressure relief holes, transfer vent holes, and holes with notes of not being blocked. At the same time, select the holes with separate notes and block them separately.

[0049] S2. Confirm the material of the hole to be plugged by multi-level step-by-step query: The judgment method is summarized in Table 1. This method has been verified to have high accuracy and strong versatility. Figure 1 The query and judgment can be carried out according to the logical process, which can save judgment time, improve judgment efficiency and significantly save working time.

[0050] 2-1 Perform a first-level query to query the hole plugging requirement information. The hole plugging requirement is N or Y;

[0051] 2-2 If the hole plugging requirement is N, enter the secondary query to query the item type information:

[0052] If the item type information is "-, / , None", concrete plugging is used; otherwise, enter the third-level query to query the plant type; the plant type is BRX or non-BRX; BRX means reactor plant;

[0053] If the plant is BRX, perform a level 4 query to query the item type information. If the item type is an air duct, use concrete to seal it. Otherwise, enter the level 5 query to query the displacement information. If the axial displacement or radial displacement is ≤20mm, use JSF-L fireproof silicone foam to seal it. If it does not meet the axial displacement or radial displacement ≤20mm, exit the query.

[0054] If the plant is not a BRX, a four-level query is performed to query the hole size information: if the single-side size of the hole is greater than 400mm, the hole is blocked with silicon cloth and filler; otherwise, silicon cloth is used to block the hole;

[0055] 2-3 If the hole plugging requirement is Y, enter the secondary query to query the item type information;

[0056] If the item type is an air duct, it is sealed with concrete; if the item type is a pipe, a three-level query is performed to query the shape information of the hole. If it is a square hole, it is sealed with a combination of concrete and special materials. If it is not a square hole, the query is exited; if the item type is neither an air duct nor a pipe, a three-level query is performed to query the biological shielding requirement information of the hole. The biological shielding requirement is N or a specific value; the special material is any one of FS-L fire-resistant silicone foam, FS-H high-density silicone rubber, and FS-R flexible silicone elastomer.

[0057] If the biological shielding requirement is N, enter the fourth-level query to find the displacement information. If the axial displacement or radial displacement is ≤20mm, use JSF-L fireproof silicone foam for plugging; if 20mm<axial displacement or radial displacement ≤40mm, use JSE-RF flexible silicone elastomer for plugging; if the axial displacement or radial displacement is >40mm, exit the query;

[0058] If the biological shielding requirement is a specific value (such as 200, 500), enter the fourth-level query to find the displacement information. If the axial displacement or radial displacement is ≤5mm, use JSE-H high-density silicone rubber for sealing. If 5mm < axial displacement or radial displacement ≤40mm, use JSE-RF flexible silicone elastomer for sealing. If the axial displacement or radial displacement is >40mm, exit the query.

[0059] The above query method can be stored in a non-temporary computer-readable medium in the form of a program. And through a one-key conversion method, multi-level query of hole information is performed to generate hole plugging methods, which greatly improves work efficiency. The plugging method in Table 1 itself is an efficient plugging technical solution obtained by technicians after many experiments and certain experience. On this basis, the present invention further searches for the logic and rules therein, and obtains a multi-level query method. While ensuring the plugging effect, it further improves the speed of determining the plugging method, thereby making construction more convenient and improving construction efficiency.
