DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Embodiment 1: See also Figure 1-6 The present embodiment discloses a road surface water seepage detection device for road construction, comprising a measuring cylinder 1, a first valve 5, a second valve 6, a base 7, a rotating assembly 8 and a supporting seat 11. A water outlet is provided on the bottom side of the measuring cylinder 1, a groove is provided on the bottom side of the base 7, a first mounting hole and a second mounting hole communicating with the groove are provided on the top side of the base 7, the first mounting hole is communicated with one port of the first valve 5, the other port of the first valve 5 is communicated with the water outlet of the measuring cylinder 1, and the second mounting hole is communicated with one port of the second valve 6.

[0028] The support seat 11 includes a horizontal circular ring, the base 7 is located inside the horizontal circular ring, the inner edge of the horizontal circular ring extends upward with a limiting cover shell, the inner wall of the limiting cover shell and the bottom side of the horizontal circular ring are fixed with a heating wire 14, the bottom side of the base 7 is lower than the bottom side of the horizontal circular ring, and the measuring cylinder 1 and the support seat 11 are connected by a connecting bracket.

[0029] The rotating assembly 8 includes an operating ring 81, which is connected to the limiting cover shell by a bearing or a rotating pin. A plurality of connecting frames 82 are fixed on the operating ring 81, and a swing frame 83 is fixed on each connecting frame 82. The swing frame 83 is located below the horizontal ring, and the connecting frame 82 passes through the gap between the limiting cover shell and the base 7.

[0030] Furthermore, the distance between the inner edge of the horizontal ring and the base 7 is 0.5-3.0 cm.

[0031] Furthermore, an external battery provides power for the heating wire 14 .

[0032] The working process and principle of this embodiment are: The staff first cleans the road surface, and then places the road surface water seepage detection device for road construction on the road surface, with the bottom side of the base 7 in contact with the road surface, and the distance between the horizontal ring and the road surface is 1.0-3.0 cm. The staff puts paraffin into the gap between the base 7 and the limiting cover, and the heating wire 14 is electrically connected to the external power supply. The energized heating wire 14 heats the paraffin to convert it into liquid. The staff rotates the connecting frame 82 and the swing frame 83 through the operating ring 81. The rotating swing frame 83 allows the liquid paraffin to fill the gap between the horizontal ring and the road surface. When liquid paraffin appears on the outer edges of the horizontal ring, the staff stops rotating the operating ring 81.

[0033] The staff closes the first valve 5 and opens the second valve 6, then adds water into the measuring cylinder 1. The staff opens the first valve 5 to allow the water in the measuring cylinder 1 to enter the groove on the bottom side of the base 7, and the air in the groove is discharged through the second valve 6. After the water flows out of the second valve 6, the staff closes the first valve 5, and the staff records the height of the liquid level in the measuring cylinder 1 at set intervals.

[0034] If the liquid level in the measuring cylinder 1 drops to a certain mark and remains basically stationary, it means that the road surface is basically impermeable or not impermeable at all.

[0035] After the road surface seepage detection is completed, the staff removes the road surface seepage detection device used for road construction, and the staff removes the solidified paraffin on the road surface, making it easier to clean the road surface.

[0036] The road surface water seepage detection device for road construction heats paraffin to convert it into liquid state, and the rotating component 8 makes the liquid paraffin flow, thereby sealing the road surface outside the base 7. The operation is simple and the influence of road surface runoff on water seepage detection is reduced.

[0037] Embodiment 2: like Figure 1-4 As shown, this embodiment discloses a road surface water seepage detection device for road construction, and its structure is substantially the same as that of the first embodiment, except that the support seat 11 of this embodiment is made of transparent plastic or transparent glass, and the liquid paraffin is transparent.

[0038] Furthermore, the swing frame 83 is an arc-shaped plate.

[0039] The working process and principle of this embodiment are: The transparent support seat 11 and the transparent liquid paraffin make it easy for the staff to observe the bubbles in the liquid paraffin. The staff rotates the connecting frame 82 and the swing frame 83 through the operating ring 81. The rotating swing frame 83 drives out the bubbles in the liquid paraffin, thereby improving the sealing effect of the paraffin on the road surface outside the base 7.

[0040] Preferably, the paraffin wax is a white solid wax block commonly found in the prior art.

[0041] Embodiment three: like Figure 7 As shown, this embodiment discloses a pavement water seepage detection device for road construction, and its structure is substantially the same as that of the second embodiment, except that this embodiment further includes a sampling assembly 9, and the sampling assembly 9 includes a closed connector 91 and no less than two splicing assemblies.

[0042] The splicing assembly includes a sampling tube 96 , one end of which is open, and the other end of which is fixed with a fixed connector 97 . A plurality of openings 93 are provided on the outer circumference of the sampling tube 96 near the opening of the sampling tube 96 , and an elastic ring 95 is fixed on the outer circumference of the sampling tube 96 .

[0043] The openings of adjacent sampling tubes 96 are connected to the fixed connectors 97 on the sampling tubes 96 by means of threads or snaps, and the opening of one of the sampling tubes 96 is connected to the closed connector 91 by means of threads or snaps.

[0044] The working process and principle of this embodiment are: Before conducting a water seepage test on the road surface, the staff uses a drilling device to drill a hole on the road, and the splicing components are vertically connected together from head to tail. A closed connector 91 is installed on the opening of the top sampling tube 96, and then the sampling component 9 is inserted into the borehole. The inner diameter of the borehole is equal to the outer diameter of the closed connector 91, and the inner diameter of the borehole is not larger than the outer diameter of the elastic ring 95. The inner diameter of the borehole is larger than the outer diameter of the sampling tube 96, and the top side of the closed connector 91 is not higher than the road surface.

[0045] During the process of water seepage detection on the road surface, the drill hole is located below the horizontal ring. When the water under the road surface flows radially, the radially flowing water enters the sampling tube 96 of the same depth, thereby sampling the radially flowing water under the road surface, which is convenient for determining the radial drainage performance of the road surface.

[0046] Furthermore, the horizontal distance between the drill hole and the base 7 is 2.0-5.0 cm.

[0047] Embodiment 4: like Figure 7 As shown, this embodiment discloses a road surface water seepage detection device for road construction, and its structure is substantially the same as that of the third embodiment, except that a through pipe 94 is fixed on the elastic ring 95 of this embodiment, both ends of the through pipe 94 pass through the elastic ring 95, and the through pipe 94 and the sampling tube 96 are arranged in parallel.

[0048] After the sampling assembly 9 is inserted into the drill hole, the through pipe 94 connects the inner cavities of each sampling tube 96. When water flows into a part of the sampling tube 96, the air in the part of the sampling tube 96 flows into other sampling tubes 96, preventing the air in the sampling tube 96 from affecting the inflow of water.

[0049] Embodiment five: like Figure 1 , 3 As shown in , 4, this embodiment discloses a road surface water seepage detection device for road construction, and its structure is substantially the same as that of the fourth embodiment, except that this embodiment further includes a needle tube 12, a fixing seat 13 is fixed to the outer peripheral side of the needle tube 12, a through hole is opened on the horizontal circular ring, and the closed connector 91 is made of elastic rubber material or elastic silicone material.

[0050] The working process and principle of this embodiment are: During the process of water seepage detection on the road surface, the through hole is located above the sampling component 9. The staff holds the needle tube 12 vertically through the fixed seat 13, and the staff blocks the top of the needle tube 12 with the hand or with an external plug. The bottom end of the needle tube 12 passes through the through hole, liquid paraffin, and the closed connector 91 into the sampling tube 96. Then the staff removes the hand from the top of the needle tube 12 or removes the external plug from the top of the needle tube 12. The needle tube 12 allows the air in the inner cavity of each sampling tube 96 to flow out freely, thereby preventing the air in the sampling tube 96 from affecting the inflow of water.

[0051] Embodiment six: like Figure 1 , 2 As shown, this embodiment discloses a pavement water seepage detection device for road construction, and its structure is substantially the same as that of the fifth embodiment, except that an elastic block 10 is fixed in the through hole of this embodiment, and the elastic block 10 is made of rubber or silicone material. The elastic block 10 prevents liquid paraffin from flowing upward from the through hole to the horizontal ring.

[0052] Embodiment seven: like Figure 1 , 3 As shown, this embodiment discloses a road surface water seepage detection device for road construction, and its structure is substantially the same as that of the first embodiment, except that a counterweight 2 is provided on the measuring cylinder 1 of this embodiment, and the counterweight 2 enables the base 7 to be placed stably on the road surface.

[0053] Embodiment eight: like Figure 1 , 3 As shown in , 4, this embodiment discloses a road surface water seepage detection device for road construction, and its structure is substantially the same as that of the first embodiment, except that the connecting support of this embodiment includes a support plate 3 fixed on the measuring cylinder 1 and no less than two support frames 4, and the two ends of the support frame 4 are respectively fixedly connected to the support plate 3 and the support seat 11, and the support plate 3 and the support frame 4 firmly fix the support seat 11.

[0054] Furthermore, a support rod is fixed between the support plate 3 and the base 7, and the support rod reduces the deflection force on the first valve 5, thereby avoiding damage to the first valve 5 and improving the safety of the road surface seepage detection device for road construction.

[0055] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
