Concrete surface roughness measuring device and method

Abstract

The invention discloses a concrete surface roughness measuring device and method. The device and the method are simple in structure and simple and convenient to operate and can meet the actual large-scale measurement requirement of engineering. The device can be used for concrete surfaces with various angles such as horizontal upward, inclined, vertical, horizontal downward and the like; and the concrete surface roughness measuring device can directly measure the convex value and the concave value of the concrete surface concerned in engineering practice, and is wide in application range. Thedevice structurally comprises a plurality of measuring teeth and a tooth box, all the measuring teeth are stacked in parallel and connected with the tooth box in a sliding mode, and marked lines are arranged on the measuring teeth. The measuring method comprises the following steps: 1, zeroing: pressing tooth tails one by one to enable the tooth tails, a zeroing plate and the tooth box to be tightly attached,all the tooth tails to be flush with one another and the heads to be flush with one another; 2, measuring: pressing the tooth tails of the measuring teeth one by one so as to enable the tooth heads to be clung to the concrete surface one by one; and 3, reading: reading roughness data through the positions of the marked lines on the measuring teeth on the graduated scale.

Description

technical field [0001] The invention relates to a measuring device and method mainly used in the fields of civil engineering, water conservancy, traffic engineering and the like, and relates to a measuring device for concrete surface roughness. Background technique [0002] In the fields of civil engineering, water conservancy, traffic engineering, etc., before spraying anti-seepage spray film on the surface of tunnel lining concrete or shotcrete, it is necessary to measure the roughness of the concrete or shotcrete surface. If the roughness does not meet the requirements, further leveling treatment is required. . [0003] The traditional method of measuring the surface roughness of concrete mostly adopts methods such as sand pouring method and silicon powder stacking method. The sand pouring method measures the volume of sand poured into the concrete surface and divides it by the sand pouring area to obtain the average sand pouring depth as the roughness of the concrete su...

Problems solved by technology

[0004] Therefore the concrete surface roughness measuring method and device in the prior art have the following deficiencies: the operation is more complicated, the efficiency is low, and it is mostly used for experimental research, and it is difficult to adapt to a large number of measurements in engineering practice; it is only suitable for horizontal upward surfaces, Inclined, vertical and horizontal surfaces are difficult to measure; in addition, the roughness measured by the above method is the average roughness of the concrete surface or an index related to the roughness.
