Description
Technical Field
The invention relates to the field of tunnel support quality detection, in particular to a tunnel full-section rack method rapid detection system and an operation control method thereof.
Background
The tunnel support comprises primary support and secondary lining, and the main quality problems are that holes appear in a support structure, and the basic reasons for generating the holes include that the tunnel excavation is poor in over-under excavation control, concrete is not fully sprayed during primary support, due arch frames cannot meet design requirements, the looseness of waterproof plate laying is not well controlled, pouring is not fully performed during secondary lining, and the like, so that the holes are singly or more. The problems directly relate to the maintenance cost of the tunnel, the service life and the train running safety. In the eighties of the last century and before, the domestic tunnel support does not have the requirement of special detection except quality inspection and process control during the reinforced support construction, and some operation tunnels have the phenomena of water leakage, block breakage and block dropping, and some operation tunnels even have local collapse, so a large amount of maintenance funds are invested or the line change construction is carried out. In the nineties of the last century, the quality control during tunnel support construction is emphasized, a batch of tunnel support quality detection equipment such as geological radar is imported from abroad, meanwhile, the detection is carried out in modes of physical knocking, drilling sampling and the like, the problems found by the detection are treated in a targeted manner, and a good control effect is achieved.
With the rising of high-speed railway construction and the opening of large-scale operation lines, the piston effect generated when a high-speed train runs in a tunnel is absent in the motion of a common-speed train, and the piston effect can extrude the tunnel supporting structure and pull force in an instantaneous semi-vacuum state, so that a hidden cavity in the tunnel supporting structure can be rapidly torn and cracked to be enlarged, and blocks fall or local collapse occurs. Therefore, in the tunnel supporting construction for the last decade, strict construction process control and geological radar ultrasonic detection are adopted, problems are found and are timely treated, and accordingly, the construction process is researched and improved, so that the ongoing supporting construction quality is guaranteed to meet the standard requirements.
The detection is carried out by using ultrasonic waves, and an ultrasonic wave emitting surface (namely an antenna) is required to be close to a detected surface (such as the inner wall of a tunnel) or a certain specified air gap value is kept, and the ultrasonic wave emitting surface moves forwards along a planned detection line at a certain speed. Before the present invention came into existence, the main frame of the inspection equipment was generally placed by a small van or a loader bucket, and the operator stood in the carriage or bucket and detected by holding the antenna close to or directly contacting the inner wall of the tunnel. Thus, the operator is very arduous, the person is prone to accidental errors in a fatigue situation, and the loader bucket carrier is a work-safety violation. In addition, when other steps have an influence on the uniform speed running of the mounted vehicle after the start of the detection operation, the operation is stopped or the vehicle needs to be avoided in advance, thereby preventing the other steps of the tunnel from operating normally.
