Problems solved by technology

[0005] In the existing bridge disease / maintenance management system in our country, the disease is usually only recorded, and there is no judgment on the level of the disease. Therefore, the record and management of the disease can only be called the disease file record system, and the classification of each disease cannot be obtained. And provide maintenance countermeasures and suggestions for maintenance and treatment
The judgment of the severity of the disease is affected by the subjective influence of the recorder, personal skill level and knowledge in the specific operation process, and the judgment of the disease often lacks a unified standard and understanding. In the current bridge maintenance / management system, it is also It is impossible to give a suggested classification for each bridge disease, and its practicality and pertinence are not enough
Therefore, it is difficult to make a more scientific and comprehensive maintenance strategy based on the above-mentioned insufficiently targeted bridge disease levels

Embodiment 1

[0079] Take the common diseases of concrete girder bridges as an example. The concrete girder bridge is discretely divided into components such as cast-in-situ box girders, piers, caps, pile foundations, and supports, among which the box girder components are composed of components such as top plates, webs, bottom plates, and diaphragms. These components are entered into the system database.

[0080] Define the possible diseases and their grades of each component / component. Take the crack disease of the transverse diaphragm of the concrete cast-in-place box girder as an example. The development trend of the disease is described as possibly intensified in the later stage (K 1 = 1); the difficulty of maintenance is described as general, requiring professionals to carry out routine repairs with small tools (K 2 =0.67); the cost of maintenance is described as low, less than 1000 yuan (K 3 =0.33); the impact on structural safety is described as general, with certain impact (K ...

Embodiment 2

[0084] Take the common diseases of cable-stayed bridges as an example. The cable-stayed bridge is discretely divided into main girders, cable-stayed cables, bridge piers, bridge piers, caps, pile foundations, bearings and other components. The cable-stayed cable components are composed of cable bodies, anchor heads and shock absorbers. These components are entered into the bridge management system.

[0085] Define the disease and its grade for each component / component. Take the cracking disease of the cable body of the cable-stayed bridge as an example. The development trend of the disease is described as possibly intensified in the later stage (K 1 = 1); the difficulty of maintenance is described as high, requiring professionals to repair large or specialized equipment (K 2 = 1); the cost of maintenance is described as medium, 1000-10000 yuan (K 3 =0.67); the impact on structural safety is described as general, with certain impact (K 4 =0.5); the impact on the use of the...

Embodiment 2

[0089] In conjunction with embodiment two, taking the cable body cracking disease of a cable-stayed bridge found at the inspection site as an example, the example of obtaining the grade of the bridge disease is set forth:

[0090] Register and log in the bridge disease classification and classification maintenance system. After registering the project and basic information of the bridge, select the stay cable component, select the cable body component, select the cable body cracking disease in the provided disease list, and fill in the relevant description of the disease. The disease information includes the disease characteristics and impact degree of the cable body cracking disease. The system automatically judges that the disease level is Level 3, and the maintenance measures provided should be dealt with. It is a durability problem or a minor equipment failure, and it should be included in the plan for centralized treatment. This suggestion can be used as a reference for u...

Abstract

The invention discloses a method and system for classifying and maintaining bridge diseases. The method comprises the following steps: S1, storing information of each component and its components of various bridge structures, and disease information of each component and its components that may occur in a database; S2, determining various influencing factors caused by the disease and their weights; S3, calculating the disease grade score of each component and its components, obtaining the disease grade and storing the disease grade in the database; S4, allowing the client to receive the disease information and the disease characteristics of the disease of a component or a component input by the user, and sending a query request to the server; S5, allowing the server to query the database according to the inquiry request, and obtaining the disease grade, the maintenance suggestion and the treatment recommendation measures corresponding to the disease. The method and the system providedby the invention can synthetically consider a plurality of influence factors according to various diseases occurring in various bridge components, classify each disease occurring in different components, and make the later maintenance decision more scientific.

Description

technical field [0001] The invention relates to the field of civil engineering bridges, in particular to a bridge disease classification and classification maintenance method and system. Background technique [0002] After nearly 20 to 30 years of large-scale bridge construction, more and more bridges have entered and are about to enter the maintenance period. Various diseases will inevitably appear during the maintenance period of bridges. The maintenance industry and managers are faced with the problem of how to classify these diseases and adopt corresponding countermeasures. [0003] There are many types of diseases on bridges, the causes of which may be related to various aspects such as materials, design, construction, use and maintenance, etc. The severity of their impact on bridges is not consistent, and the measures and urgency to be taken are also different. all the same. Some diseases need to be repaired in time, some diseases can be further observed, and some di...
