Method for identifying profile evolution characteristics of bricks in construction waste filler based on color sorting

Abstract

The invention discloses a method for identifying profile evolution characteristics of bricks in construction waste filler based on color sorting, which comprises the following steps: S1, screening construction waste regenerated filler, drawing a grading curve, collecting an image of the regenerated filler in construction waste roadbed filler, and adjusting the color value of the image of the regenerated filler; s2, determining evaluation parameters of particle contours in the regenerated filler; s3, performing a mechanical experiment on the regenerated filler, and calculating the particle breakage rate before and after the mechanical experiment according to the grading curve; s4, calculating a correlation coefficient between the evaluation parameter of the particle contour and the particle breakage rate before and after the mechanical experiment; and S5, contour evolution law analysis is carried out, and contour evolution characteristic analysis of the bricks in the construction waste roadbed filler is completed. The secondary crushing behavior of the soft component bricks in the regenerated filler is disclosed, and cognition on the pavement performance of the construction waste regenerated filler is deepened.

Description

technical field [0001] The invention belongs to the technical field of contour evolution, and in particular relates to a method for identifying the contour evolution characteristics of bricks in construction waste fillers based on color selection. Background technique [0002] Construction waste meets the requirements of building materials required for roads, especially when mixed with a certain proportion of soil with good properties, it can be used in roadbed construction. This method is not only convenient to obtain materials, but also reduces engineering costs and reduces construction costs. This method is the result of technical verification, and its use in practice not only improves economic benefits, but also increases social benefits. [0003] However, the problem of using construction waste for roadbed filling is that it contains many weak components, especially bricks with low strength and high content, which are prone to secondary crushing problems during construc...

AI Technical Summary

Problems solved by technology

Existing methods can only obtain the variation trends of the mass and volume of different grades of fillers, and cannot specifically analyze which characteristic parameters of bricks are more likely to be broken and to what extent.

[0004] In summary, the existing methods cannot clearly and quantitatively analyze the secondary crushing characteristics of each brick in the recycled filler
