Intelligent control system for arch bridge erection and control method thereof

Abstract

The invention discloses an intelligent control system for arch bridge erection and a control method thereof, and belongs to the technical field of arch bridge erection. The intelligent control system for arch bridge erection comprises stayed buckle cables on an arch rib, intelligent jacks, intelligent pump stations and a control cabinet, wherein the intelligent jacks are arranged on the two sides of the arch rib and connected with the stretching ends of the stayed buckle cables, the intelligent pump stations are connected with the intelligent jacks, and the control cabinet is connected with the intelligent pump stations; a stress measurement system and a displacement measurement system are arranged in the control cabinet and both connected with the intelligent pump stations; strain sensors are arranged in the arch rib and connected with the stress measurement system in the control cabinet. By means of the intelligent control system for arch bridge erection and the control method thereof, in the concrete pouring process of the arch rib of an arch bridge, arch rib deformation and stress can be intelligently controlled along with different time periods of poured concrete loading, it is ensured that the displacement of the arch crown is within a reasonable range, the instantaneous stress of steel tubes does not exceed the standard, and a reasonable initial line form is formed.

Description

technical field [0001] The invention relates to the technical field of arch bridge erection, in particular to an intelligent control system and control method for arch bridge erection. Background technique [0002] At present, the use of cable-stayed buckles to adjust the arch ribs is that before the arch ribs are closed, the axis of the arch ribs needs to be adjusted; during the process of pouring concrete into the steel pipe, a small amount of cable-stayed buckles are required to intervene in load adjustment to reduce instantaneous stress and ensure construction safety; Before the temporarily set living hinge of the arch foot is solidified, the initial stress and line shape in the arch rib need to be adjusted. [0003] The traditional load adjustment method of cable-stayed buckle is to use manual operation handle type oil pump to drive the jack, and tension one by one. The traditional cable-stayed buckle-mounted load adjustment method has disadvantages such as low constru...

Problems solved by technology

The traditional cable-stayed buckle hanging load adjustment method has disadvantages such as low construction efficiency, easy error in the reading of the oil pressure gauge when the pointer of the oil pump swings, untimely response, and long cycle time.
