Problems solved by technology

[0004] The existing prefabricated lining technology is mainly used for new shield tunnels, and some attempts have been made in the new stage of highway engineering. The prefabricated lining structure is almost blank in the field of operational disease reinforcement and treatment, with little accumulated experience and no supporting construction methods. Although some scholars have proposed The idea of ​​steel corrugated plate reinforcement in operation tunnels, but there are large differences between steel corrugated plates and concrete and reinforced concrete structures in terms of product type, structural size, connection method, etc., and the relevant ideas of steel corrugated plates cannot be applied to prefabricated lining structures

Embodiment Construction

[0040] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] A construction method for prefabricated treatment of operational disease tunnels, comprising the following steps:

[0042] S1: Identification of disease treatment objects;

[0043] S1-1: Combined with the manifestations of the disease, preliminarily determine which type of tunnel disease is crack, water leakage, block loss, frost heave, corrosion and aging;

[0044] S1-2: Combining the geological survey data, design parameters, construction records, monitoring data, regular inspection history and inspection results of the diseased section, compare the theoretical research results of the determined cause of the disease type, and confirm the cause of the target tunnel disease;

[0045] S1-3: Combined with the damage of the original lining structure on site, it is obtained according to Appendix B of "Technical Specifications for Highwa...

Abstract

The invention discloses an operating diseased tunnel fabricated treatment construction method applied to the field of tunnel engineering disease treatment. Based on a traditional fabricated lining structure construction working method, the characteristics of diverse types and different degrees of operating diseased tunnels and the requirements of tunnel operating for timeliness and safety are combined, the processes of disease treatment object identification, treatment range selecting, fabricated lining designing, lining segment production, matched machine and tool selection, determining of anon-site construction scheme and the like are combined, and thus the operating diseased tunnel fabricated lining structure treatment construction method is put forward. The disease treatment method has the advantages that the quality is reliable, rapidness and stability are achieved, adaptability is high, the accelerating working speed is high, the mechanical degree is high, and traffic interference is less.

Description

technical field [0001] The invention belongs to the field of tunnel engineering disease treatment, and in particular relates to an assembly-type treatment construction method for operational disease tunnels Background technique [0002] With the deepening of highway engineering, a large number of tunnels have shifted from new construction to operation. As the service time of tunnels increases, design and construction defects gradually appear, and road tunnel diseases widely occur. The appearance of cracking, water seepage, block falling and other diseases can damage the visual perception and distract the driver's attention, and cause safety accidents, causing serious economic losses and social impact. In view of the current situation of the disease, how to treat it quickly after discovery has always been a research hotspot. [0003] In engineering applications, treatment measures such as arch replacement, spraying, steel belt, and three-lining are relatively common, but the...
