Large-span bridge construction monitoring and management equipment based on BIM technology

Abstract

The invention discloses large-span bridge construction monitoring and management equipment based on a BIM technology, which belongs to the technical field of bridge construction management and controland comprises a stand column and an intelligent control system arranged on the stand column. A driving groove is formed in the top of the stand column, a cover plate is fixedly connected to the top of the stand column corresponding to the driving groove, and a bearing is clamped to the top of the cover plate. A first motor, a second motor, an electric push rod, a first information acquisition device, a second information acquisition device, a flaw detector, a remote controller, a microcontroller, a central processing unit, a BIM storage module and a BIM editing module are designed to be matched with one another, misoperation accidents can be avoided to a high degree, in cooperation with the BIM technology, a worker can observe the three-dimensional volume dynamic scene of a large-span bridge construction monitoring part like being personally on the scene in a remote monitoring room, and the large-span bridge construction monitoring and management equipment has image management and global view.

Description

technical field [0001] The invention belongs to the technical field of bridge construction management and control, and in particular relates to a large-span bridge construction monitoring and management device based on BIM technology. Background technique [0002] Long-span bridges refer to bridges spanning large rivers, rivers and seas, urban viaducts, etc. The bridge deck is mostly composed of steel boxes with hollow structures, commonly known as steel box girders, and bridges with this structure are sometimes referred to as steel box bridges. Due to the large span, the up and down vibration amplitude of the bridge deck itself is also large. For example, when the load is loaded, the central area of ​​the bridge deck is designed to allow an amplitude of as much as 1 meter (that is, the bridge deck is allowed to sink by 1 meter): steel has poor heat capacity, and its surface temperature varies with the environment. The temperature varies with the temperature, and the hollow...

Problems solved by technology

[0005] The purpose of the present invention is: in order to solve the existing shortcomings of the existing large-span bridge construction monitoring equipment in the process of use, when it is necessary to watch a certain detail, most of the monitoring equipment is built directly to adjust the phenomenon The focal length has high requirements on the performance of the monitoring equipment, and by adjusting the focal length, although it can be observed at a close distance, the monitoring range of the monitoring equipment is reduced, the overall view is poor, and the construction work observed by the relevant staff in the monitoring room Most of the site is plane structure information, which is not conducive to the staff to judge the cause of the error. A BIM-based large-span bridge construction monitoring and management equipment is proposed.
