Movable tunnel comprehensive detection system

The utility model discloses a movable tunnel comprehensive detection system which comprises a detection vehicle, a fixing system, a supporting system and a detection system body. The fixing system, the supporting system and the detection system body are arranged on the detection vehicle. The detection system body comprises a color photography system, a control device and a multi-channel data collecting device. The fixing system is arranged on the detection vehicle and used for fixing the supporting system. The supporting system is used for installing the detection system body. The detection system body is used for shooting pictorial information of the inner surface of a tunnel. The control device is used for controlling the detection system body to work. The multi-channel data collecting device is used for receiving and storing information collected by the detection system body. Combination of a plurality of kinds of technology is adopted, and therefore the movable tunnel comprehensive detection system can achieve fast detection on healthy states of the tunnel structure. Accordingly, precision of detected results is high, and contrastive analysis of healthy state development of the same project can be achieved on the basis of detected results of many times in different periods. Compared with the prior art, the movable tunnel comprehensive detection system has the advantages of being fast, free of channel sealing, high in precision of detected data, and capable of building up a long-term digitization databank for carrying out precise comparison.
