Problems solved by technology

The exposed stone cement concrete pavement has anti-skid performance, reduces noise, eliminates reflective glare, and has good drainage performance. At present, there is no good detection device that can guarantee the accurate detection of various indicators of the new road surface, and human-made photographs of the road surface are prone to shaking, resulting in the photos taken cannot accurately reflect the various indicators of the new road surface, and thus cannot Accurately know the performance of the new pavement. Therefore, there is an urgent need for an exposed concrete road surface function detection device and its detection method. It is not only easy to disassemble, but also can accurately collect road surface information, and then obtain various indicators of the road surface through data analysis. Through comparison and calculation, the performance of the new road surface can be obtained, and the laying situation of the new road surface can be further grasped

Embodiment 1

[0046] refer to Figure 1-11 , the present invention provides an exposed stone concrete road surface function detection device, which is arranged on the road surface 31, and the detection device is directly placed on the road surface 31. The road surface 31 is provided with a detection box, and the detection box is a detachable structure, which is convenient to carry The top surface of the detection box is provided with a camera part, wherein the camera part adopts the camera 12; the top of the side wall of the detection box is provided with a number of first light sources 28, and the bottom of the side wall of the detection box is provided with There are a plurality of second light sources 30, the top and bottom of the side wall of the detection box are respectively fixed with second mounting seats 29, the second mounting seats 29 are provided with internal threads, and the first light source 28 and the second light source 30 are respectively provided There are external threa...

Embodiment 2

[0075] refer to Figure 12 , the only difference from the first implementation is that, in order to better detect the darkness in the box, the first shading mechanism is externally buckled with a second shading mechanism, and the second shading mechanism includes a shading cloth 9. The shading cloth 9 is buckled on the detection box. outside the body.

[0076] The shading cloth 9 is made of black velvet cloth, and eight clips are fixed on the black velvet cloth, of which the top four are matched with the shading frame 8 on the top of the detection box, and the bottom four are matched with the shading strips 7 on the side wall of the detection box. In cooperation, the setting of the shading cloth 9 can not only block the gap of the detection box, but also cover the gap between the detection box and the road surface 31, which absolutely guarantees the darkness in the detection box.

Embodiment 3

[0078] refer to Figure 13-14 The only difference from the second embodiment is that the shading cloth 9 is fastened with a clamp 29, which is firmer and more convenient than the fixing method in the second embodiment. The shading cloth 9 is not easy to move, is more firm, and ensures the darkness in the detection box.

Abstract

The invention discloses an exposed concrete road surface function detection device and a detection method thereof.The exposed concrete road surface function detection device is arranged on a road surface, a detection box is arranged on the road surface and is of a detachable structure, a camera shooting part is arranged on the top face of the detection box, and a plurality of first light sources are arranged at the top of the side wall of the detection box; a plurality of first light sources are arranged at the bottom of the side wall of the detection box body, a plurality of second light sources are arranged at the bottom of the side wall of the detection box body, light rays of the plurality of first light sources irradiate the center of a detected road surface, light rays of the plurality of second light sources irradiate the center of the top of the detection box body, and a light supplementing mechanism is arranged on the side wall of the detection box body. Light rays of the first light source and the second light source are reflected to the light supplementing mechanism, and a first shading mechanism is arranged outside the detection box body; road surface information is accurately collected, then all indexes of the road surface are obtained through data analysis, the performance of the new road surface is obtained through comparison and calculation, and the laying condition of the new road surface is further mastered.

Description

technical field [0001] The invention relates to the technical field of road surface detection, in particular to a functional detection device for exposed stone concrete pavement surfaces and a detection method thereof. Background technique [0002] The exposed stone cement concrete pavement is a cement concrete pavement in which the coarse aggregate is exposed on the road surface to form a rough surface. The basic principle is to spray the dew-stone agent on the road surface of the fresh concrete to stagger the hardening speed of the thin layer of the road surface and the main body of the concrete. When the main concrete has a certain initial strength, the cement mortar of the thin layer of the road surface that has not yet had the initial strength is removed, so as to realize the purpose of exposing the surface of the rough and fine aggregate of the road surface. Since the surface mortar is removed from the exposed stone cement concrete pavement and the aggregate is direct...
