Description

technical field [0001] The invention belongs to the field of tunnel detection equipment, and in particular relates to a tunnel lining detection and cleaning device. The tunnel lining detection and cleaning device involved in the present invention can not only effectively avoid obstacles during operation, but also improve the detection quality of the device by cleaning the tunnel lining surface in time. Background technique [0002] The tunnel is an engineering building buried in the ground, and the excavation of the large section of the tunnel will cause damage to the surrounding ground, which is likely to cause deformation and collapse of the tunnel. Therefore, after the completion of the tunnel, the lining of the tunnel must be effectively tested to ensure the strength and quality of the lining so as to effectively prevent tunnel safety accidents. The problems that often occur in the lining are insufficient lining thickness and voids behind the lining. At present, there ...

The problems that often occur in the lining are insufficient lining thickness and voids behind the lining

At present, there are two common detection methods for tunnel lining. One is the manual hammering method. Experienced construction workers use a hammer to strike the detection position, and judge whether there is a cavity behind the lining according to the sound. This method is labor-intensive. The efficiency is low and the detection results are subject to human subjective judgment; another method is to use geological radar detection, using a lifting platform to raise the detection personnel to a certain height, and the detection personnel lift the geological radar to make it contact with the vault. This method also requires It consumes a lot of manpower and time, the safety of the inspectors is extremely poor, and it greatly interferes with the transportation activities of the tunnel

At present, a detection device that replaces manual lifting has also appeared, but its lack of flexibility will easily cause a lot of pressure on the ground radar antenna and the vault, resulting in damage to the radar antenna. In addition, there are often wires and lighting devices on the tunnel vault. When the device It is inevitable to encounter wires and lighting devices during the inspection, which will cause economic losses. At the same time, if there are debris attached to the lining surface, the radar antenna will not be in direct contact with the vault, which will have a great adverse effect on the inspection quality. In addition, the location information of the inspection And inspection quality information is often manually recorded and checked, which greatly reduces the efficiency of inspection work
