Problems solved by technology

[0004] During the monitoring process of the device disclosed in this patent, due to the single monitoring method and the inability to effectively analyze the monitoring data, it lacks more accurate early warning methods. The device has defects such as low efficiency, untimely early warning, and lagging analysis and evaluation. It brings potential safety hazards to the construction party during use, and is not suitable for multi-line overlapping construction of tunnels

Abstract

The invention provides an urban tunnel multi-line overlapping construction settlement monitoring and early warning system and method, belongs to the technical field of building construction, and solves the problems that some existing tunnel settlement monitoring and early warning devices are too single in monitoring means, monitoring data cannot be effectively analyzed, and early warning is not timely. The urban tunnel multi-line overlapping construction settlement monitoring and early warning system comprises an intelligent monitoring unit, a deformation mechanism and control theory unit, a data transmission processing unit, a safety early warning unit, an intelligent tunnel cloud computing and service platform and a client service system. According to the system and method, monitoring means are richer, monitoring data are analyzed through a database obtained through experimental testing, BIM three-dimensional modeling and the AI artificial intelligence technology are organically fused and innovatively applied, the system operation efficiency is improved, the system is more intelligent, early warning is more timely and accurate, potential safety hazards in the construction process are effectively reduced, and the system and method are suitable for tunnel multi-line overlapping construction.

Description

technical field [0001] The invention belongs to the technical field of building construction, and relates to an early warning system, in particular to a subsidence monitoring and early warning system and method for multi-line overlapping construction of urban tunnels. Background technique [0002] With the development of urbanization, tunnel excavation projects are usually located in dense urban buildings, or around roads and bridges. In these areas, pedestrians and traffic flow are dense. If not handled properly, it will not only bring serious economic losses to the construction unit. , and will threaten the lives of pedestrians around, may cause major safety liability accidents, affecting the construction and development of the entire city. Tunnel construction is very complicated, and there are many unknown hidden dangers, so it is difficult to achieve intrinsic safety. However, through reasonable monitoring and early warning methods, timely discovery of safety hazards and...
