Embodiment Construction

[0022] An embodiment of the present invention provides a tunnel crack detection and repair device, such as Figure 1-7 As shown, set on crack 1. It includes a pre-detection mechanism 4 and a repair grinding mechanism 28 , both of which correspond to the crack 1 , and the pre-detection mechanism 4 includes a detection assembly 8 and a drive assembly 6 . The detection assembly 8 is connected to the driving assembly 6 , and the detection assembly 8 corresponds to the crack 1 . The detection assembly 8 includes an inserting board 9 , a plurality of baffles 11 and an inserting rod 10 , the inserting board 9 is connected to the drive assembly 6 , and a plurality of inserting rods 10 are movably inserted in the inserting board 9 along the height direction of the inserting board 9 . The baffles 11 are arranged at the bottom of the insertion rod 10 , and the edges of two adjacent baffles 11 are in contact with each other. The driving assembly 6 includes a bottom plate 7, a housing 3,...

Abstract

The invention provides a tunnel crack detecting and repairing device. The tunnel crack detecting and repairing device is arranged on a crack. The tunnel crack detecting and repairing device a pre-detection mechanism and a repairing and polishing mechanism; the pre-detection mechanism and the repairing and polishing mechanism both correspond to a crack; and the pre-detection mechanism comprises a detection assembly and a driving assembly. The detection assembly is connected with the driving assembly, and the detection assembly corresponds to the crack. The detection assembly comprises an insertion plate, a plurality of baffles and insertion rods, and the insertion plate is connected with the driving assembly. According to the tunnel crack detecting and repairing device, the pre-detection mechanism and the repairing and polishing mechanism are matched with each other. Therefore, the device has the function of detecting the depth of the crack. Personnel can determine, through the pre-detection mechanism, places where cracks need to be cut and repaired and places which only need to be polished, so that the cutting area is reduced. The wall integrity is ensured to the greatest extent. Meanwhile, the repairing mode is more scientific and reasonable.

Description

technical field [0001] The invention relates to the technical field of tunnel equipment, in particular to a tunnel crack detection and repair device. Background technique [0002] The existing tunnel crack repairing method is to completely cut off the crack part, and then fix it on the cut by erecting keel reinforcement. Concrete is then poured in to complete the patch and fix. However, due to the limited ductility of concrete, the end of the most distal crack tends to become shallower and shallower during the cracking process. And this kind of small cracks are not so much cracks as cracks, and if such cracks are not treated, they tend to hide dirt easily, and then slowly expand. And if it is removed directly, the cracking depth is only a shallow layer, which is often not worth the candle. Expanded repair area. It is difficult for personnel to repair, and at the same time, repairing is also damage to the wall as a whole, so the repair range should be reduced as much as p...
