Description

Technical Field

[0001] The utility model relates to the technical field of engineering detection equipment, in particular to a road surface water seepage meter. Background Art

[0002] The asphalt pavement water permeability meter is an instrument used to measure the water permeability coefficient of asphalt mixture pavement and rolled asphalt mixture specimens. The water permeability rate reflects the water permeability performance of the asphalt pavement. In the specific test process, it is necessary to first draw a line with an annular ring, and apply sealing material to the drawn part to prevent the water in the measuring cylinder from leaking out of the base during the test, affecting the test results. However, the annular ring currently used is used separately from the pavement water permeability meter. Each time, it is necessary to use chalk to draw the inner and outer circles respectively according to the annular ring, which takes a lot of time and affects the detection efficiency. At the same time, since the annular ring is placed separately from the pavement water permeability meter, it is easy to lose, affecting the use of the pavement water permeability meter.

[0004] According to the technical solution provided in the embodiment of the present application, the pavement water permeability meter includes a base, to which a measuring cylinder is fixedly connected via a connecting tube, a marking ring is slidably arranged on the lower end surface of the base, the marking ring is an inner ring and an outer ring fixedly connected via a connecting rod, and the inner ring and the outer ring are both rotatably connected to the base; when the inner ring and the outer ring rotate relative to the base, the marking balls located on the lower end surfaces of the inner ring and the outer ring use the colored dye in the inner cavity of the inner ring and the outer ring to mark.

[0005] Furthermore, the longitudinal cross-sections of the inner ring and the outer ring are both convex-shaped structures, which are convenient for sliding connection with the base.

[0006] Furthermore, the marking balls on the inner ring can roll on the bottom end surface of the inner ring, and the marking balls on the outer ring can roll on the bottom end surface of the outer ring. The marking balls are connected to the inner cavity, and a sealing port is provided on the inner cavity to realize the loading of colored dyes and the marking of the marking balls.

[0007] Furthermore, a rotating rod is provided on the outer ring, and the upper end of the rotating rod is slidably connected to a slide groove on the side end surface of the base. The slide groove is annular to facilitate the rotation of the scribing ring.

[0016] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0017] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] Pavement water seepage meter, such as Figure 1 As shown, the upper end surface of the base 1 is fixedly connected to the measuring cylinder 3 through the connecting pipe 2, and a switch valve (not shown in the figure) is arranged on the connecting pipe 2, and an exhaust valve is arranged on the upper end surface of the base 1.

[0019] like Figure 1 and Figure 2 , Figure 3 As shown, a scoring ring 4 is slidably arranged on the lower end surface of the base 1, and an inner ring 42 of the scoring ring 4 is fixedly connected to an outer ring 43 through a connecting rod 41. The inner ring 42 is located at the inner edge of the lower end surface of the base 1, and the outer ring 43 is located at the outer edge of the lower end surface of the base 1. A U-shaped rotating rod 7 is arranged on the outer ring 43, and one end of the rotating rod 7 is fixedly connected to the outer ring 43, and the other end is slidably connected to the annular slide groove 11 on the side end surface of the base 1, so that the rotating rod 7 can drive the outer ring 43 and the inner ring 42 to slide on the horizontal plane relative to the base 1;

[0020] like Figure 3 and Figure 4 As shown, the inner ring 42 and the outer ring 43 are both convex structures, and the lower end surface of the base 1 is provided with a groove for placing the inner ring 42 and the outer ring 43, so that the inner ring 42 and the outer ring 43 can slide in the groove without falling out of the groove. At the same time, the inner ring 42 and the outer ring 43 are both provided with an inner cavity 6, and a marking ball 5 is provided on the bottom end surface of the inner ring 42 and the outer ring 43, which is connected to the inner cavity 6. When a colored dye is installed in the inner cavity 6, the marking ball 5 can bring the colored dye in the inner cavity 6 out of the inner cavity 6 when rolling, thereby achieving marking.

[0021] Before use, firstly, the colored dye is loaded into the inner cavity 6 through the sealing openings of the inner ring 42 and the outer ring 43; then the whole device is placed on the road surface that has been swept with a broom and a brush, and then the rotating rod 7 is manually rotated to make the rotating rod 7 slide in the slide groove 11, and then the outer ring 43 rotates with the rotating rod 7. Since the inner ring 42 and the outer ring 43 are fixedly connected by the connecting rod 41, the inner ring 42 also rotates, that is, it rotates on the horizontal plane relative to the base 1. Since the marking ball 5 is located on the inner ring 4 2 and the bottom end surface of the outer ring 43, so when the marking ring 4 rotates, the friction between it and the ground is small, and it can rotate easily. When the marking ball 5 contacts the ground, there is still friction between it and the ground. Therefore, when the outer ring 43 and the inner ring 42 rotate, the marking ball 5 will rotate relative to the outer ring 43 and the inner ring 42. At this time, the marking ball 5 can bring out the colored dye in the inner cavity 6 and mark the position where the marking ball 5 moves below the inner ring 42 and the outer ring 43, that is, the annular ring marking is realized;

[0022] After marking, take out the device, apply putty powder or quick-drying glue manually, and then press the whole device tightly on the putty powder or quick-drying glue for sealing, and then place the counterweight on the device to prevent the water in the measuring cylinder from flowing out of the base 1 during measurement and affecting the measurement result.

[0023] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the invention involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also should cover other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical scheme.
