Description

Flaw detection device for concrete pipe sheet Technical Field The utility model relates to the field of concrete pipe pieces, in particular to a concrete pipe piece flaw detection device. Background The concrete segment is a prefabricated concrete member for constructing underground projects such as underground tunnels and subways, is generally arc-shaped or annular, and is assembled to form a firm tunnel lining structure through splicing, so that the concrete segment is widely applied in urban subway construction, stable support and protection are provided for subway lines, and the tunnel can be ensured to be safely used for a long time under complex geological conditions. The defect detecting device is a device for detecting internal defects of materials or components, the principle of the defect detecting device is based on various physical phenomena, such as ultrasonic waves, rays and the like, and because the defects of cracks, hollows, looseness and the like are possibly generated in the interior of the defect detecting device due to factors such as raw material quality, stirring technology, vibration condition, collision in the transportation and installation process and the like in the production process of a concrete pipe sheet, if the defects are not found in time, the defects can be gradually developed and expanded under the long-term stress and environmental effect after the pipe sheet is put into use, and finally the stability and the safety of a tunnel structure are influenced, therefore, the defect detecting device is required to be utilized to comprehensively detect the concrete pipe sheet before the concrete pipe sheet is used, and smooth construction and long-term stable operation of underground engineering are ensured. At present, in the detection process of the concrete duct piece, manual pushing and flaw detection devices of personnel are required to carry out mobile detection on the outer wall of the duct piece, and because the detection area of the duct piece is large, the personnel are required to push and flaw detection devices for a long time, so that the detection efficiency of the personnel pushing and flaw detection devices is low. Disclosure of utility model Based on the above, the utility model aims to provide a concrete segment flaw detector, so as to solve the technical problem that the efficiency of detecting the concrete segment by personnel through manually pushing the flaw detector is low.
