Shield tunneling management and auxiliary decision support system solutions


Shield tunneling management and auxiliary decision support system solutions

1. Project background

With the gradual acceleration of urbanization, as of the end of 2019, there were only 14 cities in the country with a total mileage of more than 300 kilometers under construction. Among the 43 cities approved by the National Development and Reform Commission, most cities have not yet formed a complete urban rail system. The network cannot meet the actual needs of urban public transportation. At the same time, the state proposes to create a “metropolitan circle on the rail” to promote the integrated development of urban rail transit and the city. In the future, urban rail transit will be deeply integrated with other transportation systems on the one hand, and will also be deeply integrated with the development of urban related industries on the other. Therefore, China's urban rail transit is expected to usher in a golden development period. In addition, the overall management of the urban rail construction industry is extensive, and the cost is huge. Security accidents have caused tens of billions of dollars in economic losses in the past ten years, and refined management of enterprises is imminent.

Based on the shield construction requirements in the construction of urban rails, Yakong Technology has established a shield tunneling management and auxiliary decision support system solution. The shield tunneling construction plan and scheduling is the core, based on the data generated during the construction process, combined with industry The advanced MES concept and technology in production and operation management, from the management links of construction period, safety, quality, cost, equipment, etc., through the plan-driven real-time monitoring and scheduling of personnel, equipment, materials, construction, environment and other resources in the construction process, Realize the intelligent collaborative management of the tunneling construction work, the digital management of the construction process, the dynamic management of equipment operation, the refined management of quality, safety, and material energy consumption, and the integration with other information systems of the enterprise, so as to realize the digitalization of the shield construction process. Management goals such as networking, automation, visualization, intelligence and refinement.

2. scene-oriented

  • The shield construction industry has a large management span. Lack of a multi-person collaborative management mechanism, there are incident blind spots, on-site information filtering is serious and out of sync, opaque, not timely, shared, incomplete, and untrue;
  • Numerous on-site engineering materials. The workload is large and the utilization of data is low.
  • Numerous information systems. System entry workload is large.
  • The on-site personnel and equipment are complicated, the construction and maintenance experience is seriously lost, and the knowledge accumulation is lacking. It is impossible to form an expert database or experience database to guide training and construction, and it is difficult to guarantee the safety, quality and construction period of the construction;
  • Safety and quality accidents occur frequently at the construction site; there are few pre-warnings during the process, and it is difficult to trace after the incident. There are often no cases, no experience, and no guidance during the incident, and it is impossible to fully understand and grasp the actual situation of the project;
  • Equipment management decision-making lacks data support; the tracking and early warning mechanism of equipment status is not perfect, and there are risks of abnormal working conditions and abnormal conditions of equipment, such as cutter head wear and mud cake.

3. program details

1) Tunneling plan and scheduling

Provides the function of formulating the main plan of the tunneling construction and the process operation plan. By adjusting relevant conditions, multiple versions of the plan can be generated for users to choose a more reasonable plan for execution, and the construction plan algorithm can be used to assist in scheduling;

2) Digging risk management

Based on GIS technology, the three maps and one table are managed to realize the management of risk points investigation and evaluation, excavation progress marking, segment selection, monitoring point layout, settlement monitoring, etc. Real-time monitoring of construction safety-related parameters, timely alarm for parameter abnormalities, and issuing safe operation instructions. Provide a basis for the statistical analysis of safety issues during the period and to guide the construction risk management in the next phase.

3) Tunnelling quality management

Realize the whole process of recording and tracking the "three inspections" of the segment. At the same time, it can monitor the tunneling quality parameters in real time, and adjust the parameters through warning reminders to ensure that the assembly quality and axis deviation are within a reasonable range. The statistical analysis of construction quality provides a reference basis for the next step of construction quality management work.

4) Engineering information management

Through the process management of the excavation instruction sheet and technical disclosure, the approval and issuance of operation documents and operating procedures can be accurately executed; the paperless records of technical disclosure, shift records, construction logs and receiving documents during the construction process can be realized and quickly inquired And traceability.

5) Device management

Realize the dynamic management of equipment ledger, usage history, maintenance, maintenance knowledge base, maintenance and shutdown information, and multi-dimensional analysis of the parameters of real-time monitoring of each equipment. It can understand the health of equipment in time, assist in maintenance and dynamically adjust the construction operation plan.

6) Energy and material consumption management

Count the real-time and historical consumption of oil, mortar, electricity, water and other materials during the construction of the project, and provide data support for project cost statistics.

7) Warehouse management

Realize the management of the material warehouse, emergency material warehouse and the project office company warehouse's various procurement plans, warehouse entry and exit, and inventory management, and perform statistical analysis on the use of materials.

8) Personnel management

Realize personnel scheduling and attendance management, while realizing the management of special operations personnel, dormitory assets, and dynamic analysis of entry and delivery personnel and special equipment personnel;

9) Visualized management of construction site

Keep abreast of the progress of each process on site, quickly coordinate the problems between each process; monitor the entire process of tunneling safety, quality, schedule, cost and other data, and correct various hidden dangers in time;

4. the core value of the program

  • Realize the full interconnection of human, machine, material, law, environment, energy, measurement and other elements, laying the foundation for the realization of transparent chemical field and fine management;
  • Based on the industrial Internet architecture, realize the collaborative management of the company layer, project layer and various processes that integrate the cloud side and end, and establish a complete closed-loop collaborative system;
  • Realize the transparency of the construction site; real-time control of production progress, equipment status, process parameters, safety and quality parameters, etc., to improve the response speed of handling abnormal events.
  • Change from post-event accountability to pre-event prevention and during-event guidance; fundamentally prevent safety and quality problems in the construction process, strengthen supervision and reduce accidents;
  • Complete product traceability; record all data of human, machine, material, method, environment, energy, and measurement in the production process to realize two-way complete traceability of products;
  • Realize paperless office; reduce costs and improve work efficiency;
  • Realize all-round and refined management; according to the construction site production plan and real-time progress, various departments are encouraged to work together, so that the project manager can incorporate formalization, standardization, and institutionalization of the safety, quality, schedule, and cost of the construction project. Refined management reduces construction risks, saves costs, and improves production efficiency.
