Prior to this, the protection measures for drainage pipelines were generally to remove, intercept, reroute and other engineering reinforcement and maintenance measures for drainage pipelines without considering the situation of the drainage facilities themselves, the environmental factors of the drainage facilities and the risk level of the drainage facilities. Relocation measures, this kind of treatment measures are blind and empirical to a certain extent, and the protection effect on drainage facilities cannot achieve the expected effect
[0003] At the same time, in the existing technology, there is currently no assessment method for the safety risk analysis and judgment of drainage facilities in China. The main difficulty lies in the large difference in the construction age of drainage facilities, the complex structure, and the wide distribution and high density of drainage facilities. There are many safety risk factors related to construction. In October 2013, the State Council promulgated the "Regulations on Urban Drainage and Sewage Treatment", which clearly stipulates the maintenance and protection of drainage facilities
However, because different individuals have different awareness of drainage facilities and have different grasps of regulations, norms and standards, the analysis and judgment of drainage facility safety risks cannot be unified

[0196] Example 1: The pipeline parameters are as follows:
[0197]
[0198] 1) Weight calculation
[0199] Synthetic weight of pipeline parameters W=weight of Ci relative to Bij*weight of Bij relative to Ai*weight of Ai relative to A. See the specific calculation method Figure 7 . Figure 7 The numbers in parentheses are the weights of each factor.
[0200] Composition weight of section size W1=0.266*0.066*0.192=0.0034
[0201] Synthetic weight of aging condition W2=0.138*0.105*0.192=0.0028
[0202] Composition weight of structural defects W3=0.236*0.239*0.165*0.192=0.0018
[0204] Interface form synthesis weight W5=0.218*0.161*0.192=0.0067
[0205] Basic form synthesis weight W6=0.761*0.152*0.192=0.022
[0206] Combination weight of operating load W7=0.238*0.236*0.192=0.01

Abstract
The invention relates to an intelligent grading judgment method for drainage facility safety protection. According to first to four grades of index factors affecting the drainage facility safety protection, effect weight of all the factors in drainage facility safety risks and specific environment of drainage facilities, drainage facility risk grades under different factors or combination of multiple factors are judged with a fuzzy comprehensive evaluation method, corresponding specific measures for drainage facility safety protection are provided, the subjectivity of grading evaluation of drainage facility safety protection is reduced, the calculation workload is reduced, and the accuracy of corresponding specific measures for drainage facility safety protection is improved.
Description
technical field [0001] The invention relates to a judging method for the safety protection of drainage facilities, in particular to a classified intelligent judging method for the safety protection of drainage facilities. Background technique [0002] In order to relieve urban traffic pressure and make full use of urban underground space, there are more and more incidents that drainage facilities cannot operate normally and safely. Prior to this, the protection measures for drainage pipelines were generally to remove, intercept, reroute and other engineering reinforcement and maintenance measures for drainage pipelines without considering the situation of the drainage facilities themselves, the environmental factors of the drainage facilities and the risk level of the drainage facilities. Relocation measures, this kind of treatment measures are blind and empirical to a certain extent, and the protection effect on drainage facilities cannot get the expected effect. [0003] ...
