Description

Technical Field

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

[0002] At present, pavement water permeability meters are commonly used to measure the water permeability of asphalt pavements. The pavement water permeability meters currently on the market include a measuring cylinder, an upper plate, a joint pipe, a base, a bracket, a weight block and an accessory marking ring. Before the test, it is necessary to place the marking ring on the pavement, and use chalk to draw marks along the inner and outer rings of the marking ring respectively. A layer of sealing material is applied between the inner and outer marking rings to form a sealing ring, and the base is pressed hard on the sealing ring to make a seal between the base and the pavement.

[0003] However, in the prior art, due to the unevenness of the road surface, water will flow out from between the base and the sealing ring during measurement. At this time, the usual solution is to cover the outer edge of the base with a layer of sealing material after the base is pressed tightly on the sealing ring to strengthen the sealing effect between the base and the road surface. Although this can solve the problem of water leakage, it will waste too much sealing material, and when there is a lack of sealing material around, the measurement cannot be continued, which brings unnecessary trouble to the staff.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0033] like Figure 1-Figure 6 As shown, a road surface water seepage test device in one embodiment of the utility model includes: a main support plate 1, a lower penetration mechanism 2 and a sealing mechanism 3.

[0034] like Figure 1-Figure 2 As shown, a plurality of thin supporting rods 105 are fixedly connected below the main support plate 1, which are used to fix the main support plate 1 and the sealing base 301. A plurality of fixing blocks 101 are fixed on the main support plate 1, which are used to fix the two ends of the downward pressing curved rod 103, so that the downward pressing curved rod 103 is not easy to fall off. A downward pressing curved rod 103 is arranged between a pair of fixing blocks 101, which is used to facilitate the staff to squeeze downward, so that the gap between the sealing base 301 and the road surface can be blocked by the sealing rubber ring 303, and thus it is not easy to leak, so that the test data is accurate.

[0035] Among them, fixed bearings 102 are fixedly connected between the two ends of the downward bending rod 103 and a pair of fixed blocks 101, which are used to fix the downward bending rod 103, so that the downward bending rod 103 is easy to rotate, thereby facilitating the operation of the staff.

[0036] In addition, a bracket 104 is fixed on the water storage measuring cylinder 201, and a groove is cut on the bracket 104, so that the downward bending rod 103 can be hooked by the bracket 104 when it is rotated to a vertical state, and is not easy to rotate downward, which facilitates the storage and transportation of the device and reduces space occupancy.

[0037] like Figure 1-Figure 4 As shown, the lower infiltration mechanism 2 is installed on the main support plate 1. The lower infiltration mechanism 2 includes a water storage cylinder 201 for storing water to facilitate the test of the water permeability of the road surface. A lower leakage pipe 202 is fixedly connected to the bottom of the water storage cylinder 201 to transport water to the road surface. The water storage cylinder 201 is engraved with scale lines 203, so that the staff can observe how much water has infiltrated downward, which is convenient for the staff to calculate.

[0038] like Figure 1-Figure 4 As shown, a control valve 204 is installed on the lower leakage pipe 202 to provide space for the rotation of the blocking turntable 205. The blocking turntable 205 is rotatably connected inside the control valve 204 to block the downward flow of water in the lower leakage pipe 202, making it easier for staff to control the progress of the test.

[0039] Specifically, a fixing sleeve 206 is fixed on the main support plate 1, and the water storage measuring cylinder 201 is fixed on the inner wall of the fixing sleeve 206, which is used to fix the water storage measuring cylinder 201, so that the water storage measuring cylinder 201 is not prone to tilting and shaking, thereby improving the fixing effect of the water storage measuring cylinder 201.

[0040] like Figure 3-Figure 4 As shown, the plugging turntable 205 is fixedly connected with a control handle 207, which is used to drive the plugging turntable 205 to rotate, so as to control the water flow in the water storage cylinder 201 to flow downward, providing conditions for testing the water permeability of the road surface. The control handle 207 is provided with a connecting sleeve 208, which is fixed on the control valve 204 to improve the sealing performance, so that the water flow is not easy to leak from the gap between the control handle 207 and the control valve 204, thereby improving the sealing effect.

[0041] like Figure 1-Figure 6 As shown, the sealing mechanism 3 is arranged below the main support plate 1, and the sealing mechanism 3 includes a sealing base 301, which is used to seal the road surface, so that the water flow is not easy to leak during the test. An exhaust pipe 302 is installed on the sealing base 301, which is used to discharge air to the outside, and an arc groove is cut at the bottom of the sealing base 301 to facilitate the water flow to penetrate downward. A sealing rubber ring 303 is fixed at the bottom of the sealing base 301, which is used to improve the sealing effect and make the water flow not easy to leak. The sealing base 301 is fixedly connected to the end of the plurality of thin support rods 105 away from the main support plate 1.

[0042] like Figure 5-Figure 6As shown, a pair of sealing arc plates 304 are fixed on the inner wall of the sealing rubber ring 303 to seal the lower air inlet hole 309 so that water is not easily leaked out from the lower air inlet hole 309 .

[0043] like Figure 1-Figure 6 As shown, a rotating control rod 305 is inserted into the exhaust pipe 302 for exhausting air to the outside, so that the air between the sealing base 301 and the road surface is not likely to affect the water permeability test, and a ring groove matching the sealing arc plate 304 is cut at the bottom of the rotating control rod 305, so that the rotation of the rotating control rod 305 is not easily affected by the sealing arc plate 304, so that the sealing arc plate 304 can block the lower air inlet 309. A disc 307 is fixed on the top of the exhaust pipe 302.

[0044] Specifically, a pair of weight blocks 308 are provided on the sealing base 301 to provide weight so that the sealing base 301 can fit closely with the road surface, thereby reducing water leakage and improving the sealing effect. A pair of lower air inlet holes 309 and a plurality of upper air outlet holes 306 are drilled on the rotating control rod 305 to exhaust air to the outside.

[0045] When in use, the staff first demarcates the area to be inspected, then cleans the area, and then aligns the sealing base 301 and presses it down, and then places the counterweight 308 on the sealing base 301 to provide gravity for pressing down, and then the staff pulls a pair of downward pressing bent rods 103 so that the downward pressing bent rods 103 can rotate to a horizontal state, which makes it easier for the staff to push downward, so that the sealing rubber ring 303 can block the gap between the sealing base 301 and the ground, thereby improving the sealing effect;

[0046] Then pour a certain amount of water into the water storage cylinder 201, and then turn the control handle 207 and the disc 307 to allow the water in the water storage cylinder 201 to be discharged downward from the lower leakage pipe 202, and the air between the sealing base 301 and the ground will be discharged from the upper exhaust hole 306. When the upper exhaust hole 306 discharges water outward, the staff rotates the disc 307 to block the lower air inlet 309, and then add a certain amount of water to the water storage cylinder 201. At this time, the staff can calculate the water permeability coefficient of the road surface by observing the amount of water in the water storage cylinder 201 that penetrates downward within a certain period of time.

[0047] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
