Multi-element comprehensive quantitative detection method for health state of pipe gallery structure

Abstract

The invention relates to a multi-element comprehensive quantitative detection method for the health state of a pipe gallery structure, which comprises the following steps of: firstly, establishing various disease indexes for settlement, section rotation, surface crack, deformation joint opening and water leakage of all sections of pipe galleries in a detection section by using various monitoring sensors, three-dimensional laser scanning and other detection technologies and data; the average level of a certain type of diseases of all segmented pipe galleries and the difference level of the segmented diseases can be scientifically represented; secondly, on the basis of each disease index and a multivariate factor evaluation theory, establishing a multivariate comprehensive quantitative evaluation index for various diseases in the detection section, and comparing the multivariate comprehensive quantitative evaluation index with an index allowable value to realize comprehensive and quantitative evaluation of the overall health state of the pipe gallery structure in the detection section; the informatization and scientization level of pipe gallery operation and maintenance management and disease prevention and control can be effectively improved.

Description

Technical field [0001] The present invention belongs to the field of operation and maintenance of underground integrated gallery, and in particular, the present invention relates to a multivariate integrated quantitative detection method for the health state of the gallery structure. Background technique [0002] At present, the underground integrated gallery is built by the construction of the casting, and it will be buried in the urban underground. It is a few kilometers short, and the length is dozens of kilometers. It usually sets a multi-channel structure variant in its length. The gallery structure is divided into multiple sections. Moreover, since the innermost closed state is in the area of ​​the gallery, the ground conditions are complex, and the more and more underground integrated gallery is in terms of poor formation conditions, surface traffic vibration load, peripheral construction and groundwater erosion. Under the influence, there is no uniform settlement, structu...

Problems solved by technology

[0009] Aiming at problems such as non-uniform settlement disease, cross-section rotation disease, surface crack damage, deformation joint opening disease, water leakage disease and other problems that may occur during the operation of the underground comprehensive pipe gallery structure, there are complex influencing factors, many types and affected Due to the influence of multiple sections, there is still a lack of a complete set of effective technical means to conduct a comprehensive and comprehensive inspection of the structural health status of all sectioned pipe galleries along the entire length of the line, and it is difficult to scientifically characterize the average level of a certain type of disease in all sectioned pipe galleries The level of disease difference with each sub-section makes it difficult to scientifically evaluate the overall health status and disease degree of the full-length pipe gallery, and it is difficult to effectively guide the disease control and prevention of the underground comprehensive pipe gallery
