Problems solved by technology

[0011] The purpose of the present invention is to establish a large-span railway bridge inspection system based on BIM technology in view of the inaccurate location of the disease in the inspection process of the current long-span railway bridge, and the inconsistency of the description of the type of disease and the degree of deterioration. The general disease database of long-span railway bridges formulates the classification codes of long-span railway bridge components, and establishes a one-to-many relationship between components and disease types with component IFD classification codes to realize the integration of BIM technology and bridge inspection process

Embodiment 1

[0044] Such as figure 1 As shown, Embodiment 1 of the present invention provides a long-span railway bridge inspection system based on BIM technology. Information query module, disease entry module and remote upload module;

[0045] The planning module, according to the maintenance strategy and the overall situation of the bridge, prepares the annual, quarterly, monthly and weekly inspection plans of the bridge, and realizes the connection between the inspection plan and the BIM model;

[0046] The disease library building block of the visualized BIM model is used to import the disease library and the lightweight BIM model, and realize the correlation between the lightweight BIM model and the disease library; the corresponding disease recommended maintenance time is formulated for different disease types , the disease database is scalable, and unique disease types can be added according to the actual situation;

[0047] By building a general disease database for long-span ra...

Embodiment 2

[0068] Such as figure 2 As shown, embodiment 2 of the present invention provides a kind of large-span railway bridge inspection method based on BIM technology, and this method comprises:

[0069] Step 1) Start the disease library building module of the visualized BIM model, import the disease library and the lightweight BIM model, and realize the correlation between the model and the disease library;

[0070] According to the structural part-disease or defect category-disease or defect sub-category, it is divided into layers, and the degradation classification is defined for each disease or defect sub-category. Based on IFD, a unified component classification and coding system for long-span railway bridges is constructed, and based on this, the association between component categories and disease databases is realized, which is convenient for statistical analysis and targeted formulation of maintenance plans;

[0071] Step 2) Start the plan preparation module, carry out brid...

Abstract

The invention discloses a large-span railroad bridge inspection system and method based on the BIM technology. The system comprises a planning module and a visual BIM model disease library construction module which operate at a server side, and an information consulting module and a disease input module which operate at a client side. The plan making module is used for making a bridge inspection plan. The disease library construction module of the visual BIM model is used for realizing correlation between the lightweight BIM model and the disease library and constructing the disease library ofthe visual BIM model. The information consulting module is used for downloading the inspection plan and the large-span railroad bridge lightweight BIM model from the server to consult the inspectionplan and bridge attribute information. The disease input module is used for checking corresponding parts of the bridge according to the inspection plan, selecting members with diseases through a BIM model, selecting specific types and degradation levels of the diseases according to actual disease conditions, and finally realizing accurate positioning and unified and standardized description of thediseases.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a BIM technology-based inspection system and method for large-span railway bridges. Background technique [0002] As of the end of 2016, my country's railway operating mileage was 124,000 kilometers, of which high-speed railway operating mileage exceeded 22,000 kilometers, ranking first in the world. The modern management of railway infrastructure operation and maintenance represented by bridges has become increasingly urgent. At present, the operation and maintenance of long-span railway bridges in my country is mainly based on inspection, periodic maintenance, and comprehensive maintenance, and the mode of "separate maintenance and maintenance" is implemented in management. Inspections mainly include periodic inspections, temporary inspections, hydrological observations, special inspections, and verification tests; periodic maintenance is generally carried out on the entire eq...
