specific Embodiment approach 1

[0019] Specific implementation mode one: combine Figure 1 to Figure 4 Describe this embodiment, a kind of annular sand paving device for measuring the depth of road surface structure described in this embodiment comprises inner ring body 1 and outer ring body 2, inner ring body 1 is arranged in outer ring body 2, and inner ring body 1 An annular sand groove 3 is provided between the outer wall of the ring body 1 and the inner wall of the outer ring body 2 .

[0020] In this embodiment, both the inner ring body 1 and the outer ring body 1 are made of stainless steel.

specific Embodiment approach 2

[0021] Specific implementation mode two: combination image 3 Describe this embodiment, the inner diameter D of the inner ring body 1 of a kind of ring sand laying device for measuring the depth of the road surface structure described in this embodiment is 290mm-310mm, the outer diameter d of the outer ring body 2 is 350mm-370mm . Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0022] Specific implementation mode three: combination image 3 Describe this embodiment, the inner diameter D of the inner ring body 1 is 300 mm, and the outer diameter d of the outer ring body 2 is 360 mm.

[0023] The technical effect of this embodiment is: the inner diameter D and the outer diameter d are too small, the coverage area of ​​the ring (measuring sand) is too small, and the measurement results cannot fully explain the actual structure depth of the road surface at the measuring point; the inner diameter D and the outer diameter d are too small. When it is large, the ring is inconvenient to carry, and consumes too much stainless steel to manufacture and also consumes too much sand during measurement. Therefore, considering the measurement results of the traditional manual sanding method and the general actual structural depth of the pavement, choosing D = 300mm and d = 360mm can fully explain the actual pavement structural depth of the measuring point, and at the...

Abstract

The invention relates to a ring sanding device and method, and particularly relates to a ring sanding device and method for determining the surface structure depth of a road, which aims to solve the problem of large errors of the conventional manual sanding device and method. The ring sanding device comprises an inner ring body and an outer ring body, wherein the inner ring body is arranged in the outer ring body, and an annular sand groove is formed between the outer side wall of the inner ring body and the inner side wall of the outer ring body. The device and the method are used for determining the surface structure depth of the road.

Description

technical field [0001] The invention relates to a circular sand-spreading device and method, in particular to a circular-ring sand-spreading device and method for measuring the structural depth of a road surface. Background technique [0002] In the process of measuring the depth of pavement surface structure, the error of manual sanding method is relatively large. There are many reasons for this. For example, there is no standard for the method of sand filling. The degree of tightness is different, which affects the amount of sand; there is no standard for the push plate used for spreading sand. In the previous method, the thickness of the rubber sheet was 1.5-2.5 mm, and the material was steel, and there were also wooden boards; only sand was used to fill the pores on the road surface. The volume can be used to calculate the structural depth. If the sand is spread insufficiently, the sand above the datum plane of the road surface will also be included in the volume of the ...
