Description

Pointer swing rod type tunnel lining maintenance and detection integrated trolley Technical Field The invention relates to a pointer swing rod type tunnel lining maintenance and inspection integrated trolley, and belongs to the technical field of tunnel inspection and maintenance. Background At present, common tunnel lining concrete curing methods include natural curing, spray curing, steam curing, standard curing and the like. The natural maintenance is maintenance without any auxiliary mode under the condition of the temperature and the humidity of the tunnel environment, and is only suitable for the specific condition that the temperature and the humidity in the tunnel are close to the standard value, and the universality is poor. The spray curing means that water is sprayed on the surface of concrete by using certain pressure to carry out moisture preservation and curing, so that the cost is low, the application is most common, but the low-temperature environment has influence on curing operation, and the difference between the water temperature and the internal temperature of the concrete needs to be controlled not to be too large. Steam curing means that a steam generator or a steam boiler is used for generating high-temperature and high-humidity gas to cure concrete, so that the curing effect is good, the construction period can be shortened, the curing effect of winter construction can be guaranteed, the curing cost is high, the economical efficiency is poor, and the method is not easy to popularize and use in a large range. The standard curing means that water is sprayed to the surface of a concrete test piece or the concrete test piece is soaked in water at the standard temperature of 20+/-1 ℃ so as to keep the humidity of the concrete surface to be more than 95%, and the standard curing is commonly adopted in a laboratory, but is not applicable to actual curing of tunnel lining. According to the nondestructive testing regulations for railway tunnel lining quality (TB 10223-2004), nondestructive testing technologies such as a geological radar method, an ultrasonic method, a rebound method and the like are widely applied to quality acceptance and operation period disease detection links in the tunnel construction process, and can be used for detecting lining thickness, steel arch distribution, back hollows or incompact, insufficient strength and internal defects of a water-containing lining. The tunnel lining quality detection is carried out by adopting a manual operation mode, the data acquisition quality cannot be ensured under the influence of the working state and experience level of personnel, the workload is large, the efficiency is low, the stability is poor, spot measurement can only be carried out on key areas, the large-scale batch detection of the whole space of the tunnel lining cannot be realized, and the risk of collision and falling of personnel and equipment exists. The tunnel lining detection vehicle carrying the geological radar equipment effectively improves the efficiency and the automation degree of lining quality detection, but carrying the two-dimensional geological radar can only detect a limited number of measuring lines along the longitudinal mileage direction of the tunnel, so that the full-coverage fine detection of the lining is difficult to achieve, and hidden danger of missed detection exists. Moreover, the lining quality self-checking in the tunnel construction process is in a form, so that the problems of insufficient self-checking and even non-checking of a construction unit exist, and huge later hidden danger is brought. In summary, the current tunnel lining maintenance and detection equipment has higher artificial dependency, lower automation and intellectualization degree, certain problems still exist in the aspects of efficiency, informatization and the like, continuous full-coverage detection of the tunnel lining cannot be realized quickly, independent mechanical equipment is needed to be relied on for maintenance and detection, the maintenance and detection operation process is complex, and the quality is low. Disclosure of Invention Aiming at the technical problems in the prior art, the invention provides the pointer swing rod type tunnel lining maintenance and detection integrated trolley which realizes automatic control of maintenance and detection, and rapidly switches between detection and maintenance modes, thereby facilitating synchronous self-inspection of construction units in the maintenance process and effectively improving the quality and efficiency of detection and acceptance.
