Description

Technical Field

[0001] The utility model belongs to the technical field of electric power civil engineering, and more specifically, particularly relates to a hollowing detection device. Background Technique

[0002] In electric power civil engineering, hollowing phenomena may occur, mainly manifested as poor bonding between the concrete surface and the aggregate, and between the aggregates, resulting in the appearance of cavities on the concrete surface. These cavities may reduce the load-bearing capacity and durability of the structure, and even pose safety hazards. Therefore, a hollowing detection device is needed to detect the hollowing phenomena. The existing hollowing detection devices mainly consist of hollowing hammers. By gently tapping the ground or wall surface with the hollowing hammer and listening to the sound to judge whether there is a hollowing sound, and using a marker pen to mark the areas with hollowing for subsequent processing.

[0003] The existing application number CN202321613660.8, this utility model is applicable to the technical field of house detection, and discloses a hollowing detector. One side of the pushing plate is fixedly installed with a pushing rod, the side surface of the pushing rod is fixedly installed with a mounting plate, the mounting plate is limited and slides inside the hollow tube, the side surface of the mounting plate is fixedly installed with a plug-in frame, and a marker pen is detachably plugged inside the plug-in frame. A movable groove is opened in the middle of the side of the hollow tube, and the marker pen is limited and slides in the movable groove. Sliding grooves are opened inside both ends of the side of the hollow tube. The technical solution of this utility model connects the pushing plate and the pushing sleeve through a transmission rod, so that when the detection personnel need to mark the hollowing position, they only need to push the pushing sleeve from the outside of the hollow tube, so that the marker pen placed inside the plug-in frame can be moved out of the hollow tube, and then the detection personnel do not need to change hands for the entire hollow tube and the marker pen to mark the hollowing position on the wall, improving the detection efficiency of wall hollowing.

[0004] Based on the above, the existing hollowing detection devices mainly rely on the staff to manually tap the ground or wall surface with a hollowing hammer and judge whether there is a hollowing problem according to the sound emitted. Prolonged tapping detection will cause the staff's physical strength to decline and the wrists to ache, affecting the detection efficiency. When detecting in a large detection area, it greatly increases the labor intensity of the staff, and the detection efficiency is too low, affecting the construction progress.
