Railway construction organization design should highlight the two main lines of track laying engineering and joint commissioning and testing and operation test. The track laying engineering line is the control line for the overall arrangement of various railway station pre-projects. In railway engineering, the focus should be on ensuring that the construction period of roadbed, bridges and tunnels does not touch the track laying line; the joint commissioning and testing and operation test line is the control line for the overall arrangement of post-station supporting projects and the adjustment of various subsystems. In post-station projects, the focus should be on ensuring that the construction period of four electricity, building construction, and station facilities does not touch the joint commissioning and testing line.

[0051] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0052] In the prior art, during the guiding construction organization design stage and the implementation construction organization design stage, when there are major changes in the objective factors of the project, including major changes in the construction plan, major changes in the total project period or the important node period, serious discrepancies between the actual construction progress and the construction schedule, and major changes in the supply and demand of machinery, equipment, materials and labor, the track laying project period will exceed the track laying project line, the project cannot be advanced as planned, the construction period is delayed, and manual adjustment is required; the present invention proposes a dynamic management system for railway engineering construction organization design. When there are major changes in the objective factors of railway engineering construction, the system prepares a construction process planning scheme through multiple railway engineering project import terminals, a construction process compilation subsystem, a construction process planning review terminal, a cloud server, multiple project construction terminals, a project supervision terminal and an early warning subsystem in combination with computer development languages ​​and algorithms.

[0053] Figure 1 The figure is a schematic diagram of the components of a railway engineering construction organization design dynamic management system according to an embodiment of the present invention. Specifically, the present invention provides a railway engineering construction organization design dynamic management system, which includes:

[0054] Multiple railway engineering project import terminals 100 are deployed in multiple project design parties and are used to import railway engineering main body information, construction unit information, supplier information and construction demand information. The project design party is a professional unit with sufficient qualifications and experience, responsible for comprehensive survey, design and planning of railway engineering projects, so as to design railway construction projects that meet the project's own construction needs and comply with relevant regulations of railway engineering. The project design party uses the railway engineering project import terminal to import railway engineering main body information, construction unit information, supplier information and construction demand information. Specifically, the railway engineering main body information includes construction location, construction impact range and construction environment, the construction unit information includes construction technology, construction speed and construction quality, the supplier information includes equipment, materials and construction cost required for the project, and the construction demand information includes construction period, construction requirements and construction budget. By integrating the railway engineering main body information, construction unit information, supplier information and construction demand information, the construction process planning scheme of the railway engineering project is assisted in preparation, the construction main body and the project design party are promoted to work together, accurate information support is provided, and the progress, cost, quality and resources of the railway engineering project are efficiently managed and planned and allocated, so as to ensure the quality and efficiency of the construction of the engineering project.

[0055] The construction process compilation subsystem 200 includes a database module and a construction organization algorithm module. The database module is used to import or update the construction organization duration index library and the process logic relationship through a specified link; the construction organization algorithm module is used to store and execute a preset construction organization network diagram algorithm to compile a construction process planning scheme based on the main information of the railway project, the construction unit information, the supplier information, the construction demand information, the construction organization duration index library and the process logic relationship; the construction organization network diagram algorithm is a calculation method for constructing a double-code network diagram based on the calculation time parameters of multiple railway engineering projects.

[0056] The construction period index library in the database is a relationship between engineering quantities and indicators set according to logical relationships to achieve the lowest cost and shortest construction period on key routes. The construction period index library for railway projects includes:

[0057] Critical path analysis indicators: The critical path determines the shortest completion time of the project. When the sub-projects on the critical path are delayed, the entire project will be delayed. Therefore, this indicator is an important indicator for monitoring the progress of the project.

[0058] Project estimated time and actual completion time data: Project estimated time, actual completion time and historical data help to make more accurate and reasonable predictions and plans for future construction progress.

[0059] Resource allocation and utilization indicators: Resources include manpower, materials and equipment. Reasonable allocation of resources and improved resource utilization will help the smooth progress of construction and reduce costs.

[0060] The construction organization algorithm module implements the construction organization network diagram algorithm through the calculation method of the time parameters of the double-code network diagram. The mutual constraints and interdependence between the sub-projects in the engineering project constitute the logical relationship of the double-code network diagram. The logical relationship includes process relationship and organizational relationship. The process relationship is determined by the process or work procedure of each sub-project. The organizational relationship is the sequence relationship determined according to the organizational arrangement needs or resource allocation needs between the sub-projects. The construction process planning scheme is compiled according to the construction organization duration indicator library and the process logical relationship and the calculation method of the double-code network diagram time parameters. In some embodiments, the execution steps of the construction organization network diagram algorithm include steps S101 to S104:

[0061] Step S101: Decompose the railway project into multiple sub-projects, and calculate the construction time parameters of each sub-project according to preset standards. The construction time parameters include the earliest start time, the earliest finish time, the latest start time and the latest finish time.

[0062] Step S102: The total time difference is calculated according to the latest start time and the earliest start time of each sub-project, and the difference between the earliest start time of the latter and the earliest completion time of the former between adjacent sub-projects is used as the free time difference of the former.

[0063] Step S103: The sub-projects when the total time difference and the free time difference are both zero are key tasks, and the sub-projects corresponding to the key tasks are arranged in a sequential order to form a key route that runs through the entire railway project construction.

[0064] Step S104: According to the key lines and based on the main information of the railway project, construction unit information, supplier information, construction demand information, construction organization and duration indicator library and process logic relationship, sub-projects other than key tasks are deployed into the construction process to prepare a complete construction process planning plan.

[0065] Furthermore, a free time difference of zero means that the earliest start time of the latter of the adjacent sub-projects is the same as the earliest completion time of the former, that is, the time interval between the two sub-projects is zero. The critical line of the railway project is the line with the longest total duration among the lines running through the beginning and the end. The critical line is not unique. When the time parameter of a sub-project in the railway project changes, the critical line will also change. The preparation method of the construction schedule of the railway project includes the preparation method of the bar chart schedule and the preparation method of the engineering network plan, wherein the engineering network plan includes the double-code network plan, the single-code network plan, the double-code time-scale network plan and the single-code overlap network plan. In addition to using the double-code network diagram to prepare the construction process planning scheme of the railway project, the construction organization algorithm module also includes: single-code network diagram, double-code time-scale network plan diagram, single-code overlap network plan diagram and bar chart.

[0066] The construction process planning review terminal 300 is used to review the construction process planning scheme according to the first preset standard. If the review is passed, the construction process planning scheme is marked with a version number to form a guiding construction organization plan and published, and the guiding construction organization plan is stored in a cloud server that can be remotely accessed.

[0067] Specifically, the construction process planning and review terminal is deployed in the construction unit. The review departments in the construction unit include the planning department, environmental protection department, land management department and financial department. The planning of the railway project requires the approval of the urban and rural planning department, and the environmental impact assessment report of the railway project requires the approval of the environmental protection department. In addition, the location of the railway project requires the land use right approval of the land management department, and the financial department is responsible for reviewing the use of funds for the railway project. The first preset standards include: the construction plan complies with the safety assessment and risk management requirements, the construction process procedures and time arrangements are reasonable, the use of construction funds is compliant, and the construction operations are safe.

[0068] Figure 2 It is a component module of the cloud server described in an embodiment of the present invention. In some embodiments, the railway engineering construction organization design dynamic management system also includes a cloud server 400.

[0069] The cloud server includes:

[0070] The data resource collection and management module 401 is used to store various versions of the guiding construction organization plan and the implementing construction organization plan for remote access.

[0071] The planning scheme recovery module 402 is used to recover the construction process planning scheme before the update, and the project designer applies for access to the recovered construction process planning scheme according to the construction demand.

[0072] The user management operation module 403 is used by the construction entity to manage the feasible construction organization plans stored in the cloud server and select the feasible construction organization plan that meets the construction needs.

[0073] Specifically, the cloud server collects the construction process planning scheme and the guiding construction organization scheme and implementation construction organization scheme formed after marking and integrates them into the data resource collection and management module, so that users can remotely access the database, and when the same construction requirements appear, they can quickly access the historical construction scheme and select the corresponding construction scheme that meets the construction requirements from the database, thereby improving the efficiency of the railway engineering construction organization design dynamic management system in compiling and updating the construction process planning scheme. The cloud server is a remote server that provides computer services and data storage through the Internet. The existing cloud server platforms include Alibaba Cloud, Amazon AWS (Amazon Web Services) and Microsoft Azure (Microsoft Azure).

[0074] In some embodiments, the railway project import terminal is also used to import risk construction project disposal requirements and legal construction disposal requirements. The construction organization algorithm module is used to store and execute a preset construction organization network diagram algorithm to compile a construction process planning scheme based on railway project subject information, construction unit information, supplier information, construction demand information, construction organization duration index library, process logic relationship, risk construction project disposal requirements and legal construction disposal requirements.

[0075] In some embodiments, the railway engineering construction organization design dynamic management system also includes a plurality of project construction terminals 500 and at least one project supervision terminal 600. The project construction terminal is deployed on the construction subject side, and is used to access the guiding construction organization plan stored in the cloud server, and to feedback the construction progress information to the construction process compilation subsystem; the project supervision terminal is deployed on the supervision side, and is used to feedback the supervision information to the construction process compilation subsystem, the cloud server and the project construction terminal. The supervision information of the project supervision terminal is fed back to the construction process compilation subsystem, the cloud server and the project construction terminal. When there are problems in the supervision information, the construction process compilation subsystem adjusts the construction process planning plan according to the feedback information and saves the supervision information to the cloud server, so as to supervise and adjust the construction project in real time and ensure the safety and punctuality of the construction project.

[0076] Specifically, the construction process plan approved by the construction process planning review terminal is marked as a guiding construction organization plan, which is stored in the cloud server for remote access. The guiding construction process plan in the cloud server can be accessed through the project construction terminal in the main construction party. Users can share the guiding construction process plan in the cloud server. The guiding construction organization plan guides the planning of railway engineering construction work. The disposal of risky construction projects requires monitoring, prediction and early warning of risks based on the risk control of construction projects and the identification and assessment of risks in accordance with the risk management plan. Risk control requires the joint participation of the construction unit, the main construction party and the project design party. The construction unit clarifies the quality risk control responsibilities of each construction party of the project, formulates risk control plans and work implementation methods, implements the specific responsibilities of risk control, and supervises, inspects and evaluates the risk management work of the construction parties. The project design party clarifies the engineering measures for risk control of high-risk construction projects and puts forward guiding suggestions for preventing risks. The main construction party strictly implements the formulated risk control plan and work implementation methods for the construction phase and conducts construction environmental and social environmental risk surveys. It conducts real-time tracking and monitoring of risks during the project construction process, issues early warnings for newly discovered risk events and potential risk factors, conducts timely risk identification and assessment, formulates corresponding countermeasures, strengthens quality control of building components and materials and conducts quality re-inspections to ensure that the building components and materials used on the project meet the construction requirements.

[0077] Furthermore, the construction process compilation subsystem, construction organization algorithm module, construction process planning and review terminal and cloud server are also used to update the project engineering main information, construction unit information, supplier information, construction demand information, construction organization duration indicator library and process logical relationship to form and mark the implementable construction organization plan.

[0078] In some embodiments, the construction process compilation subsystem also updates the completed and unfinished parts in the project engineering main body information based on the construction progress information.

[0079] The construction organization algorithm module is also used to recompile and update the construction process planning plan based on the updated project engineering main information, construction unit information, supplier information, construction demand information, construction organization duration indicator library and process logic relationship.

[0080] The project supervision terminal is also used to review the updated construction process planning scheme according to the second preset standard. If the review is passed, the updated construction process planning scheme is forwarded to the construction process planning review terminal.

[0081] The construction process planning review terminal is also used to review the updated construction process planning scheme according to the first preset standard. If the review is passed, the updated construction process planning scheme is marked with a version number to form an implementable construction organization plan and publish it, and the implementable construction organization plan is stored in a cloud server that can be remotely accessed.

[0082] Specifically, the situations where the construction process planning scheme needs to be updated include: when the guiding construction organization plan or the implementation construction organization plan is prepared, there is a difference between the planned construction period and the calculated construction period; when the geological conditions are beyond the prediction during the construction stage of the railway project; due to special policy reasons, the total construction period of the project or the construction period of important nodes has changed significantly; during the construction stage of the railway project, the on-site project progress is deduced based on the on-site real-time progress data and the deduction algorithm, and the project progress is predicted to exceed the reasonable warning range. The second preset standard includes: the construction process complies with the goals, tasks and responsibilities specified in the supervision outline and supervision plan, and the construction behavior complies with the quality, safety and progress requirements of the supervision unit.

[0083] Furthermore, in some embodiments, the railway engineering construction organization design dynamic management system uses the railway engineering project import terminal, construction process compilation subsystem, construction process planning and review terminal, cloud server, project construction terminal and project supervision terminal as nodes to build a blockchain network, and packages the railway engineering main body information, construction unit information, supplier information, construction demand information, guiding construction organization plan and implementation construction organization plan into the blockchain for storage.

[0084] Specifically, blockchain technology records data in multiple blocks and verifies and stores it through nodes in the network, thereby achieving data transparency, security, and immutability, providing a more reliable storage space for construction organization plans in the dynamic management system of railway engineering construction organization design.

[0085] Figure 3It is a component of the early warning subsystem described in an embodiment of the present invention. In some embodiments, the railway engineering construction organization design dynamic management system also includes an early warning subsystem 700.

[0086] The early warning subsystem includes:

[0087] The construction progress information collection module 701 is used to obtain the construction progress information fed back by the construction terminals of each project.

[0088] The construction organization plan acquisition module 702 is used to obtain a guiding construction organization plan or an immediately updated implementable construction organization plan.

[0089] The early warning processor 703 is used to review the construction progress information according to the guiding construction organization plan or the immediately updated implementation construction organization plan. When the construction progress falls behind, an alarm message is generated and sent to the project supervision terminal.

[0090] In some embodiments, the early warning subsystem further includes:

[0091] The construction environment element information collection component 704 includes a geological environment element collection module 7041 and a hydrological element collection module 7042; the geological environment element collection module is used to collect geological monitoring data of the railway project construction site according to a first set time interval, and the hydrological element collection module is used to collect hydrological monitoring data of the railway project construction site according to a second set time interval.

[0092] The early warning processor is also used to refer to the geological and hydrological standard requirements recorded in the construction demand information, to detect the geological monitoring data and hydrological monitoring data, and to generate an alarm message and send it to the project supervision terminal when the geological environment and hydrological environment do not meet the standards.

[0093] In some embodiments, the construction environment element information collection component further includes a meteorological environment element collection module 7043, which is used to collect meteorological monitoring data of the railway project construction site at a third set time interval. The early warning processor is also used to perform weather broadcasts and weather warnings during the construction process based on the meteorological monitoring data.

[0094] Specifically, the establishment of an early warning subsystem is an important means to maintain the smooth implementation and advancement of the construction process. By real-time monitoring of the construction process and obtaining construction progress information of each project, it helps to review whether the construction is proceeding according to the planned progress in the construction process planning scheme. When the progress is not as planned, it is necessary to generate alarm information and adjust the construction process planning scheme according to the existing problems to solve the problems, ensuring that the project can be completed on time as planned. By obtaining the guiding construction organization plan and the implementation construction organization plan and their problem situations and solutions, the same problems can be avoided under the same circumstances, thereby improving the efficiency and accuracy of project construction and the preparation and updating of construction process planning schemes.

[0095] Furthermore, the impacts of geological, hydrological and meteorological environmental factors include:

[0096] Geological environmental factors include geological structure and soil type. Different geological structures have a direct impact on the foundation design of engineering construction. In earthquake-prone areas or geologically active areas, special foundation treatment measures are needed to improve the seismic resistance of railway engineering buildings.

[0097] Hydrological elements include groundwater level and river flow pattern. The height and changes of groundwater level have a significant impact on construction. Excessively high or changing groundwater level may lead to soil erosion and unstable foundation. For railway projects along or across rivers, the river's flow rate, flow and sediment content will affect the design and construction of the project.

[0098] Meteorological environmental factors include temperature, precipitation, wind and climate. Extreme temperatures will affect the hardening speed and strength of concrete. Temperature changes will cause deformation and damage to building materials. Continuous rainfall will cause mud and water accumulation at the construction site. Too strong winds will affect the stability of high-rise buildings. Extreme weather will affect construction safety. These environmental factors will affect construction operations and progress.

[0099] The present invention is described below in conjunction with a specific embodiment:

[0100] 1. Meaning and symbols of time parameters.

[0101] 1. Working duration (D i―j ): The time from the start to the completion of a task.

[0102] 2. Duration (T): The time required to complete a task, generally there are three types:

[0103] 2.1 Calculation of construction period (T c ), the construction period calculated based on the network planning time parameters.

[0104] 2.2 Required construction period (T r ), the duration required by the task entruster.

[0105] 2.3 Planned construction period (T p ), the construction period determined as the implementation target based on the required construction period and the calculated construction period.

[0106] When the required construction period T is specified r When T p ≤T r ; When the required duration is not specified, the planned duration can be equal to the calculated duration, T p =T c .

[0147] LF 11―12 =min{LF12―13 ―D 12―13}=19―4=15;

[0148] The latest start time for each task is based on the LS i―j =LF i―j ―D i―j calculate:

[0155] TF 5―6 =LS 5―6 ―ES 5―6 =5-5=0;

[0156] 4.5 Calculate the free time difference of each task: The free time difference of task i-j in the network is equal to the earliest start time of the next task minus the earliest completion time of the task, which can be calculated according to the formula FF i―j =ES j―k ―EF i―j Calculations such as:

[0157] FF 1―2 =ES 2―3 ―EF 1―2 =2-2=0;

The final result is as follows Figure 4 A dual-code network diagram.

[0165] 2. Adjustment of construction process planning scheme.

[0166] 1. Situations where construction process planning requires dynamic adjustment include:

[0167] a: During the construction process planning stage, the key routes and total construction period of the railway project are calculated through the double-code network diagram. If the planned total construction period is less than the calculated total construction period, the network plan diagram needs to be adjusted. If the planned total construction period is greater than the calculated total construction period, the calculated total construction period shall be followed.

[0168] b: If unexpected situations occur during the project construction, the construction plan will be adjusted without affecting the original key lines.

[0169] c: Due to special policy reasons, the total project duration or the duration of important nodes has undergone major changes. For example, the total project duration is advanced, and it is necessary to adjust the construction process planning scheme of the existing project volume to speed up the progress.

[0170] d: During the project construction process, the real-time progress data on site and the deduction warning algorithm are used to predict whether the project progress is within a reasonable warning range. If it is not within a reasonable range, the construction process planning plan needs to be adjusted.

[0171] 2. The contents of the construction process planning adjustment include: adjusting the length of the critical route; adjusting the time difference of non-critical work; adding or reducing work items; adjusting logical relationships; re-estimating the duration of certain work; and making corresponding adjustments to resource inputs.

[0172] 3. Methods for adjusting the construction process planning scheme:

[0173] 3.1 Methods for adjusting the length of critical lines include:

[0174] a. When the actual progress of the critical path lags behind the planned progress, the unfinished critical tasks with low resource intensity or low cost should be selected to shorten their duration, and the time parameters of the unfinished parts should be recalculated and implemented as a new plan.

[0175] b. When the actual progress of the critical line is ahead of the planned progress, if the construction period is not advanced, the subsequent critical tasks with large resource consumption or high direct costs should be selected and their duration should be appropriately extended to reduce their resource intensity or costs; if the construction period is advanced, the unfinished part of the plan should be treated as a new plan, and the duration of the critical tasks should be re-determined and implemented according to the new plan.

[0176] 3.2 Methods for adjusting the time difference of non-critical work include: moving the work within the range of its earliest start time and latest completion time; extending the duration of the work; shortening the duration of the work.

[0177] 3.3 When adding or reducing work items, the following regulations should be followed: the overall logical relationship of the original network plan should not be disrupted, and only the local logical relationship should be adjusted; after adding or reducing work, the time parameters should be recalculated and the impact on the original network plan should be analyzed; when there is an impact on the construction period, adjustment measures should be taken to ensure that the planned construction period remains unchanged.

[0178] 3.4 Adjustment of logical relationships: Logical relationships can only be adjusted when actual conditions require changes in construction methods or organizational methods. When making adjustments, the originally planned construction period and other work should not be affected.

[0179] 3.5 Adjust the duration of work: When it is found that the original duration of certain work is incorrectly estimated or the conditions for its implementation are insufficient, its duration should be re-estimated and the time parameters should be recalculated to minimize the impact on the original planned duration.

[0180] 3.6 Adjust resource input: When abnormalities occur in resource supply, resource optimization methods should be used to adjust the plan or take emergency measures to minimize the impact on the construction period.
