An intelligent bridge hanging basket preloading device and its control method

Abstract

The invention discloses an intelligent bridge hanging basket preloading device and a control method thereof. The system includes a press frame module, a ground anchor module, an intelligent loading module and a monitoring module. The press frame module transmits the preload load evenly according to the section form of the box girder To each component of the hanging basket, the ground anchor module provides the application point for the application of the preload. The intelligent loading module applies the preload of the hanging basket to the hanging basket accurately in stages through the press frame module, and the monitoring module automatically Accurately record load displacement data and draw curves. The invention is mainly applied to the construction of the bridge hanging basket method, and provides a system for the hanging basket preloading with a simple structure, high degree of automation and intelligence, and has wide application prospects in the field of hanging basket preloading construction.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a hanging basket preloading technology for bridge construction, in particular to an intelligent bridge hanging basket preloading device and a control method thereof. Background technique [0002] With the continuous advancement of national infrastructure construction, the mileage of highways and railways has increased rapidly, which has effectively guaranteed the development of social economy. Prestressed concrete continuous girder bridges and continuous rigid frame bridges have the characteristics of excellent structural stress, wide application range, mature construction technology, and low construction and maintenance costs. application. [0003] The construction of prestressed concrete continuous beams and the upper main girder of continuous rigid frame bridges usually adopts the balanced cantilever pouring construction method, and the main equipment ...

AI Technical Summary

Problems solved by technology

However, there are many deficiencies in the existing hanging basket preloading methods: prefabricated concrete blocks or filling sandbags require huge manpower and material resources, and there is nowhere to use them after the hanging basket preloading is completed, and the post-processing costs are high; Concrete blocks or sandbags are easy to collide with the suspension rods of the hanging basket during the hoisting process of the crane, posing safety hazards; continuous beam bridges or continuous rigid frame bridges are box-shaped cross-sections, and the loads on each part of the hanging basket are different during the construction process , while using concrete blocks or sandbags to carry out the hanging basket preload test, evenly stacking it on the bottom mold of the hanging basket, the preload load and the actual load are quite different, which cannot truly reflect the working mechanical properties of the hanging basket; the hanging basket is loaded in stages The load depends on the statistics of the hoisting quantity of concrete blocks or sandbags. If there is an error in a single weight, the load deformation data obtained by the hanging basket is not accurate enough
