Intelligent monitoring system and method for deepwater cofferdam sinking construction

Abstract

The invention belongs to the technical field of bridge deepwater cofferdam construction, and discloses an intelligent monitoring system and method for deepwater cofferdam sinking construction. The system comprises a stress sensing module, a position sensing module, a water level sensing module, a cloud monitoring platform and a remote client, and the stress sensing module is used for measuring stress data of the side wall of the cofferdam and transmitting the stress data to the cloud monitoring platform through a wireless network; the plane position sensing module is used for measuring coordinate data of a cofferdam top measuring point and transmitting the coordinate data to the cloud monitoring platform through a wireless network; the water level sensing module is used for measuring waterlevel data inside and outside the cofferdam and transmitting the water level data to the cloud monitoring platform through a wireless network; and a parameter management system, a data management system and a safety evaluation system are arranged in the cloud monitoring platform, and the remote client is used for querying, exporting and displaying data in the cloud monitoring platform in real time and is also used for receiving and displaying safety warning signals sent by the cloud platform in real time. According to the invention, real-time monitoring and transmission of cofferdam construction data can be realized, and the safety and quality of cofferdam construction are improved.

Description

technical field [0001] The invention belongs to the technical field of bridge deep-water cofferdam construction, and in particular relates to an intelligent monitoring system and method for deep-water cofferdam sinking construction. Background technique [0002] In recent years, with the rapid development of my country's high-speed railway construction, deep-water long-span cable-stayed bridges have become more and more widely used in high-speed railway bridges, and the foundations of deep-water long-span cable-stayed bridges are mostly constructed with large steel cofferdam structures. In view of the engineering characteristics of deep water depth, high flow velocity, and thick cover layer buried in the riverbed, the subsidence construction of super-high double-wall steel cofferdam requires high control precision and high technical difficulty. During the cofferdam sinking process, the plane position deviation, inclination, wall stress and deformation, and the difference in ...
