Abstract
The invention belongs to the field of building engineering management, and relates to a pavement leveling quality analysis management system based on a concrete laser leveling machine.
Description
Technical Field
The invention belongs to the field of building engineering management, and relates to a pavement leveling quality analysis and management system based on a concrete laser leveling machine.
Background
The concrete laser leveling machine is special equipment widely applied to the field of road traffic construction and is used for leveling and repairing pavement. The height difference of the road surface is measured through the laser sensor, and the height of the laser cutter is automatically adjusted by utilizing the hydraulic system, so that the flatness and smoothness of the road surface are realized. In road traffic construction, the flatness and smoothness of the road surface have an extremely important influence on the comfort, safety and service life of driving. Therefore, it is important to analyze and evaluate the road surface leveling quality of the concrete laser leveler.
The road surface leveling quality analysis technology of the existing concrete laser leveling machine mainly focuses on monitoring road surface parameters after the completion of concrete air drying, so as to evaluate the road surface leveling quality, although the existing requirements are met to a certain extent, the analysis purpose singleness and the analysis index limitation still exist, and the concrete leveling quality analysis technology has great limitation, which is specifically expressed in the following steps: 1. the prior art neglects the important influence of the leveling operation of the concrete laser leveling machine on the pavement leveling quality, the leveling speed of the concrete laser leveling machine, the vibration level of the vibration plate and the running track of the leveling knife are limited to a certain extent, and especially the vibration level of the vibration plate can be adjusted relatively in real time according to the concrete quality condition of a to-be-leveled area so as to ensure the uniform compaction property and the leveling property of the concrete of the to-be-leveled area, and the defect of compliance analysis of the leveling operation of the to-be-leveled area of the concrete laser leveling machine in the prior art causes the pavement leveling operation process to be fuzzified, so that the precise and fine analysis of the pavement leveling quality is not facilitated.
2. The prior art lacks the instant quality monitoring and analyzing capability of the concrete laser leveling machine for the road surface leveling process. When the concrete is completely leveled, the concrete is not completely air-dried, holes, textures, crushed aggregates or ponding and the like can appear on the pavement, and the quality problem or environmental factors of the concrete in the leveling process can be reflected on the side face. However, once the concrete has been completely air-dried, problems such as holes, textures, particles or water accumulation on the road surface may disappear or develop into more serious conditions such as cracks. The existence of leveling problems cannot be found in time only through road surface quality monitoring and evaluation after complete air drying. The lack of instant quality monitoring and analysis can affect the comprehensiveness and accuracy of the overall quality result of the pavement, so that problems are difficult to discover and take corresponding measures early. In addition, the tracing of the subsequent problems becomes uncertain and cumbersome, failing to ensure a good level of effectiveness of the levelling operation and of the final road quality.
