Abstract

The invention provides a device for detecting air bubbles on the surface of concrete, which includes a mobile frame and a detection board; the inner ends of both sides of the mobile frame are sequentially connected with an upper clamping frame and a lower clamping frame from top to bottom, and the detection A block of plasticine is clamped on the detection board of the board, and the two sides of the detection board are also respectively connected with a drive shaft, and a drive gear is installed on the drive shaft, and a drive screw is fixed on the upper end of the L-shaped bracket. The outer end is also connected with a square block, and the upper end of the driving screw is respectively inserted into the inner threaded barrel through thread engagement, and a bevel gear A is installed on one set of the inner threaded barrel. Through the manual operation lever, drive the detection board and the plasticine block to move downward and turn over, and touch the concrete slab to press out the same bump as the air bubble. By turning the manual operation lever in the opposite direction, the detection board moves upward and turns upward again , so as to facilitate shooting and recording through multiple sets of cameras, and the plasticine blocks can be flattened by a leveling plate.

Description

technical field [0001] The invention belongs to the technical field of concrete air bubble detection, and more specifically relates to a concrete surface air bubble detection device. Background technique [0002] In order to ensure the construction quality of the self-compacting concrete filling layer of the ballastless track, the relevant standards require that the self-compacting concrete filling layer should be inspected on-site before construction and every time a certain amount of construction is carried out. The inspection items mainly include surface air bubbles, surface compactness, and surface filling. Degree, etc.; the construction can only be carried out after the inspection results of the peeling plate meet the requirements. For the detection of surface air bubbles, the area of ​​air bubbles is usually measured with a steel ruler or a 100-grid plate. [0003] For example, in the patent whose application number is: CN201921017540.5, a concrete surface air bubble ...
