Description

Sliding type tester for surface flatness of masonry stone

Technical Field

The utility model relates to a roughness in the hydraulic engineering construction detects technical field, concretely relates to slidingtype grout stone surface flatness tester.

Background

In the construction of hydraulic engineering, after the construction of a cast-in-place concrete structure surface, a precast concrete member surface, a grouted stone surface, a dry stone surface, a precast concrete block surface and the like is finished, the construction appearance quality index flatness is detected in a unit engineering construction quality record table, and the flatness is detected according to the specification of SL223-2008 < water conservancy and hydropower construction regulation acceptance regulation > and SL634-2012 < water conservancy and hydropower regulation unit engineering construction quality acceptance evaluation standard >, so that the flatness plays an irreplaceable role in the whole process of the construction and acceptance of the hydraulic engineering.

First, flatness measurement status

According to related detection rules and test specifications, the flatness is detected by a 3-meter guiding rule which is the most original detection means, and the method is multipurpose for detecting the road surface of highway engineering, and the flatness detection methods comprise the following steps: 1. 3m ruler method; the 3m ruler measurements were made with a single ruler to measure maximum gap and with equal distance (1.5 m) in succession. The flatness measured by the two methods has better correlation. The former is commonly used for construction quality control and inspection acceptance, and the qualification rate of a measuring section is calculated during single-ruler measurement; the equidistant continuous test can also be used for checking and accepting the construction quality, the standard deviation is calculated, and the flatness is expressed by the standard deviation. 2. Continuous flatness gauge method; the method is used for measuring the flatness of the road surface and evaluating the construction quality and the use quality of the road surface, but is not suitable for measuring the road surface with more pits and serious damage. 3. Brief introduction to vehicle-mounted bump-accumulation instrument; the method provides that the flatness of the road surface is represented by a single-direction displacement accumulated value VBI between a rear shaft and a carriage when a vehicle passes on the road surface, which is measured by a vehicle-mounted bump accumulator and is measured in cm/km. The method is suitable for measuring the flatness of the surface of the pavement so as to evaluate the construction quality and the comfort of the pavement in the service life. But is not suitable for measuring on the road surface with more pits and serious damage.

Second, the flatness measurement status of the hydraulic engineering

The flatness measured by hydraulic engineering and highway pavement engineering has substantial difference:

1. the road pavement engineering length is long, the working surface is basically a plane, and the measurement is convenient; the hydraulic engineering has more stone masonry or dry stone surfaces, and the working surface basically forms a slope protection form;

2. the second and third methods are not suitable for hydraulic engineering, the guiding rule method is a main method for measuring flatness of hydraulic engineering, but the method for detecting dam slope or dike slope protection of hydraulic engineering has certain limitation, the number of measuring result points is less, the flatness and gradient trend of the dam slope or the dike slope are analyzed, and the whole data does not have certain continuity;

3. the running rule method is used for measuring the flatness, a feeler gauge is used for measuring data, the number of reading sample points is small, and regular continuous data are not easy to form. And the guiding rule and the feeler used by the guiding rule method are two separated parts, so the carrying and the operation are not convenient.
