Whole-process intelligent control system and control method for large open caisson construction

Abstract

The invention discloses a whole-process intelligent control system and control method for large open caisson construction. The control system comprises a real-time information acquisition module, a data processing module, a comprehensive early-warning module, an intelligent decision module, a PLC device control module and a control system client. The real-time information acquisition module and the PLC device control module are installed on an open caisson structure, and the data processing module, the comprehensive early-warning module and the intelligent decision module are all integrated onan integrated server. According to the whole-process intelligent control system and control method, important parameters of each construction stage of an open caisson are monitored, so that the internal stress and the overall stability of the open caisson structure are mastered in time; and the construction site equipment is dynamically controlled according to the real-time monitoring data analysis result to adjust the posture of the open caisson, so that early-warning information is provided for safe construction, the basic construction is ensured to be smoothly carried out, and the purposesof construction guiding and feedback design are achieved.

Description

technical field [0001] The invention relates to the field of bridge caisson foundations in the field of civil engineering. More specifically, the present invention relates to an intelligent control system and control method for the whole process of large-scale caisson construction. Background technique [0002] The caisson is a shaft-shaped structure. It excavates the soil in the well, relies on its own gravity to overcome the friction of the well wall and sinks to the design elevation, and then seals the bottom with concrete and fills the well hole to make it a bridge pier or other structures. Foundation. The posture of the caisson foundation during the construction process is affected by various factors such as its own gravity and hydrological environment. It is necessary to ensure the stability of the caisson during the entire construction process. The role of caisson construction monitoring is to dynamically control the caisson according to the site monitoring data Wel...

AI Technical Summary

Problems solved by technology

This traditional monitoring method only monitors one construction stage, but does not involve other construction stages, so it is impossible to grasp the continuous force and attitude state of the caisson; in addition, the calculation analysis and construction decision-making of the traditional method are all done manually, and finally by There are time breakpoints in the process of the manager issuing construction instructions, and the defect that the instructions cannot be transmitted in real time is prone to occur in emergencies
