Description

Technical Field

[0001] The invention relates to the technical field of road surface detection, in particular to a road surface water seepage detection device for road construction. Background Art

[0002] During road construction, in order to ensure the safety and service life of the road, it is necessary to conduct water seepage detection on the road surface; water seepage on the road surface will reduce the friction coefficient of the road, increase the risk of vehicle driving, and easily lead to traffic accidents. If the road surface is in a water seepage state for a long time, it will cause aging, damage and corrosion of road materials, shortening the service life of the road.

[0003] When a pavement water seepage meter is used to detect pavement water seepage, the common water seepage meter includes a base, a measuring cylinder, a valve, a water outlet pipe and a sealing ring; for example, a Chinese patent discloses a pavement water seepage detection device for road construction (application number 202211331780.9). During the detection, the water outlet pipe and the pavement are sealed with a sealing ring, and the valve is opened to allow the water in the measuring cylinder to flow into the pavement naturally. The liquid disappearance rate in the measuring cylinder is observed and recorded to determine the water seepage coefficient of the pavement.

[0004] Since the water outlet pipe is sealed from the road surface, when the valve is opened, the water in the measuring cylinder naturally penetrates into the road surface completely relying on the water pressure of its own gravity. This makes the liquid flow rate very slow when testing road surfaces with poor water permeability coefficients. Therefore, the required testing time is very long. If retesting is required, the time required will be even longer, making it difficult to perform rapid testing. Summary of the invention

[0030] 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0032] See also Figure 1 to Figure 12 In an embodiment of the present invention, a road surface water seepage detection device for road construction includes a base 1; and a water storage cylinder 8 fixedly mounted on the base 1; the base 1 is provided with a water outlet pipe 11; The base 1 is provided with a pressure supply mechanism; the water outlet pipe 11 is provided with a sealing mechanism; a blocking mechanism is provided between the water outlet pipe 11 and the water storage cylinder 8; the pressure supply mechanism cooperates with the sealing mechanism and the blocking mechanism; The pressure-supplying mechanism includes a piston 7 that is slidably sealed with the water storage cylinder 8; the piston 7 can approach the base 1 in the water storage cylinder 8; and during the approaching process, the pressure-supplying mechanism first cooperates with the sealing mechanism to reduce the connection gap between the water outlet pipe 11 and the ground; and the pressure-supplying mechanism cooperates with the blocking mechanism to connect the water storage cylinder 8 and the water outlet pipe 11; thereafter, the piston 7 can squeeze the detection liquid in the water storage cylinder 8.

[0033] Taking the embodiment combining all the features described in the present application as an example, when in use, in the initial position, there is a gap between the lowermost end of the water outlet pipe 11 and the bottom surface of the base 1, that is, the water outlet pipe 11 does not touch the ground; in order to avoid the water outlet pipe 11 sliding in contact with the protrusion of the ground during the movement and fine-leveling of the device, causing the water outlet pipe 11 to be worn, resulting in poor sealing between the water outlet pipe 11 and the ground, thereby affecting the accuracy of the detection result.

[0034] Before testing, ensure that the water storage cylinder 8 and the water outlet pipe 11 are relatively perpendicular to the road surface to be tested; then inject a certain amount of testing liquid into the water storage cylinder 8; and start testing after the preparation work is completed.

[0035] The piston 7 is driven to approach the base 1 in the water storage tube 8 by the action of the pressure-supplying mechanism, so that the piston 7 approaches the detection liquid. During the approaching process, the pressure-supplying mechanism and the sealing mechanism cooperate with each other to seal the water outlet pipe 11 and the ground through the action of the sealing mechanism, so as to avoid the detection liquid from diffusing and flowing around from the gap between the water outlet pipe 11 and the ground during the detection process, thereby ensuring that the detection liquid can flow vertically into the road surface to the maximum extent, thereby improving the accuracy of the detection result. At the same time, the pressure-supplying mechanism will cooperate with the blocking mechanism to connect the sealed water outlet pipe 11 and the water storage tube 8 through the action of the blocking mechanism, so that the detection liquid can flow smoothly to the road surface. After that, the piston 7 will squeeze the detection liquid to speed up the rate at which the detection liquid penetrates into the road surface, observe and record the time required for the piston 7 to reach the set position, and deduce the water permeability coefficient of the converted road surface.

[0036] After the piston 7 reaches the set position, the pressure-supplying mechanism will still drive the piston 7 to slide toward the base 1, and cooperate with the blocking mechanism and the sealing mechanism to first block the water outlet pipe 11 and the water storage cylinder 8, and then release the sealing state of the water outlet pipe 11 with the road surface; to avoid the detection liquid from flowing from the connection gap to the surrounding area, causing waste of detection liquid; at the same time, it can also provide a relatively similar detection environment for subsequent re-inspections.

[0037] In another embodiment of the present invention, a bracket 101 is fixedly installed on the base 1; the pressure mechanism also includes a fixed plate 2 fixedly installed on the bracket 101, a rotating shaft 3 is rotatably installed on the fixed plate 2, a slide rod 4 is slidably installed on the fixed plate 2, and a connecting plate 5 fixedly installed on the slide rod 4 is fixedly installed with the piston 7; a pressure spring 6 is wrapped around the slide rod 4, and the two ends of the pressure spring 6 are respectively in contact with the fixed plate 2 and the connecting plate 5; a second sleeve 502 slidably connected to the bracket 101 and a first sleeve 501 slidably connected to the rotating shaft 3 are fixedly installed on the connecting plate 5.

[0038] Taking the embodiment combining all the features described in the present application as an example, when in use, the pressure spring 6 is in a fully compressed state before detection; at this time, the piston 7 is located at the farthest distance from the base 1; and a certain amount of detection liquid is injected into the water storage cylinder 8.

[0039] When in use, the compression spring 6 releases its elastic force, thereby driving the connecting plate 5 to approach the water storage cylinder 8, and the slide rod 4 slides with the fixed plate 2; at this time, the piston 7 can move synchronously with the connecting plate 5, and the piston 7 slides in the water storage cylinder 8 toward the base 1.

[0040] The piston 7 will first contact the detection liquid, and then squeeze the detection liquid to speed up the flow of the detection liquid to the road surface. Observe and record the time required for the piston 7 to reach the set position (observe the position of the slide bar 4 for judgment), so as to deduce the water permeability coefficient of the converted road surface. During this process, the first sleeve 501 and the second sleeve 502 will slide in the direction of the rotating shaft 3 and the base 1 on the bracket 101.

[0041] By speeding up the flow rate of the detection liquid toward the road surface through the pressure mechanism, the squeezing force of the detection liquid on the road surface can be increased, thereby improving the detection efficiency and avoiding the reduction of detection efficiency due to the slow flow rate of the detection liquid caused by the low permeability coefficient of the road surface.

[0042] In another embodiment of the present invention, the first sleeve 501 is fixedly installed with a first protruding column 503; the rotating shaft 3 is provided with a first inclined groove 301, a vertical groove 302, a second inclined groove 303 and a detection groove 304 which are slidably engaged with the first protruding column 503; wherein the lowermost end of the first inclined groove 301 is connected with the uppermost end of the vertical groove 302; the lowermost end of the vertical groove 302 is connected with the uppermost end of the second inclined groove 303; the lowermost end of the second inclined groove 303 is connected with the uppermost end of the detection groove 304; and a large bevel gear 305 and a first gear 306 are fixedly installed on the rotating shaft 3.

[0043] Taking the embodiment combining all the features described in the present application as an example, when in use, as the first sleeve 501 slides in the rotating shaft 3, the first protruding column 503 will first slide in the first inclined groove 301 toward the connection with the vertical groove 302, and through the extrusion fit between the first protruding column 503 and the first inclined groove 301, the rotating shaft 3 is driven to rotate, thereby driving the large bevel gear 305 and the first gear 306 to rotate.

[0044] Afterwards, the first protruding column 503 will slide in the vertical groove 302 toward the connection with the second inclined groove 303, and the rotating shaft 3 will not rotate at this time.

[0045] Afterwards, the first protruding column 503 will slide in the second inclined groove 303 toward the connection with the detection groove 304, and drive the rotating shaft 3 to rotate through the extrusion fit between the first protruding column 503 and the second inclined groove 303. Since the inclination directions of the first inclined groove 301 and the second inclined groove 303 are opposite, the rotation direction of the rotating shaft 3 is opposite, so that the substitute large bevel gear 305 and the first gear 306 rotate in the opposite direction.

[0046] The large bevel gear 305 is connected to the blocking mechanism, and the first gear 306 is connected to the sealing mechanism. The rotating large bevel gear 305 and the first gear 306 drive the blocking mechanism and the sealing mechanism to act synchronously.

[0047] The pressure-supplying mechanism, the blocking mechanism and the sealing mechanism cooperate with each other and act synchronously to improve the detection efficiency and the accuracy of the detection result.

[0048] In another embodiment of the present invention, the sealing mechanism includes a sliding sleeve 10 and a sealing sleeve 13 that are slidably engaged on the water outlet pipe 11; and the water outlet pipe 11 is wrapped with a sealing spring 12 whose two ends are respectively in contact with the sliding sleeve 10 and the sealing sleeve 13; a sealing ring 1301 is fixedly installed on the sealing sleeve 13; a second gear 9 that meshes with the first gear 306 is rotatably installed on the base 1, and a second protruding column 901 is fixedly installed on the second gear 9; and a third inclined groove 1001 that is slidably engaged with the second protruding column 901 is opened on the sliding sleeve 10.

[0049] Taking the embodiment combining all the features described in the present application as an example, when in use, when the first protruding column 503 slides in the first inclined groove 301 to the connecting point between the first inclined groove 301 and the vertical groove 302, it will drive the rotating shaft 3 to rotate, thereby driving the first gear 306 to rotate, and driving the second gear 9 to rotate through the meshing action; the rotating second gear 9 will drive the second protruding column 901 to rotate synchronously, thereby driving the second protruding column 901 to slide in the third inclined groove 1001, and the second protruding column 901 can squeeze the third inclined groove 1001 to drive the sliding sleeve The cylinder 10 slides on the water outlet sleeve 11 toward the road surface, thereby driving the sealing sleeve 13 to slide toward the road surface through the sealing spring 12; the sealing sleeve 13 will drive the sealing ring 1301 to move synchronously, so that the sealing ring 1301 contacts the road surface; in this process, the sliding distance of the sliding sleeve 10 is greater than the distance the sealing ring 1301 approaches the road surface, so after the sealing ring 1301 contacts the road surface, the sliding sleeve 10 will compress the sealing spring 12; the sealing sleeve 13 is squeezed by the elastic force of the sealing spring 12, so that the sealing ring 1301 is deformed, thereby improving the sealing performance.

[0050] The water outlet pipe 11 is sealed from the ground through the action of the sealing mechanism to prevent the detection liquid from diffusing and flowing around from the gap between the water outlet pipe 11 and the ground during the detection process, thereby ensuring that the detection liquid can flow vertically into the road surface to the maximum extent, thereby improving the accuracy of the detection result.

[0051] In another embodiment of the present invention, the blocking mechanism includes a connecting plate 16 fixedly mounted on the water storage cylinder 8, on which a small bevel gear 14 meshing with the large bevel gear 305 is rotatably mounted; a rotating plate 15 is fixedly mounted on the small bevel gear 14; a first protruding column 1501 is fixedly mounted on the rotating plate 15; a valve sleeve 17 fixedly connected to the water outlet pipe 11 is fixedly mounted on the water storage cylinder 8, a spherical stopper 18 is rotatably mounted on the valve sleeve 17, and a through groove 1801 is formed on the spherical stopper 18; a rotating rod 1802 cooperating with the first protruding column 1501 is fixedly mounted on the spherical stopper 18.

[0052] Taking the embodiment combining all the features described in the present application as an example, when in use, the first protruding column 503 will drive the rotating shaft 3 to rotate during the process of sliding in the first inclined groove 301 to the connecting point between the first inclined groove 301 and the vertical groove 302, thereby driving the large bevel gear 305 to rotate, and driving the small bevel gear 14 to rotate through the meshing action, thereby driving the rotating plate 15 to rotate synchronously, thereby driving the first protruding column 1501 to rotate synchronously.

[0053] During the rotation of the first protruding column 1501, it does not cooperate with the rotating rod 1802 at first; after the sealing ring 1301 contacts the ground, the first protruding column 1501 and the rotating rod 1802 contact each other; then the sealing mechanism will squeeze the sealing spring 12, so as to squeeze the sealing ring 1301 through the elastic force of the sealing spring 12 to deform it, thereby increasing the sealing performance; during this process, the rotating first protruding column 1501 drives the rotating rod 1802 to rotate synchronously, so as to drive the spherical stopper 18 to rotate, thereby driving the through groove 1801 to rotate (from parallel to the base 1 to perpendicular to the base 1), and during the rotation of the through groove 1801, the conduction area between the water storage cylinder 8 and the water outlet pipe 11 gradually increases (when parallel to the base 1, the conduction area is zero; when perpendicular to the base 1, the conduction area is the largest); after the water storage cylinder 8 and the water outlet pipe 11 are connected, the detection liquid in the water storage cylinder 8 can flow into the water outlet pipe 11 and flow vertically to the ground.

[0054] That is, when the first protruding column 503 slides in the first inclined groove 301 to the connection point between the first inclined groove 301 and the vertical groove 302, the piston 7 contacts the detection liquid; at the same time, the sealing mechanism is activated to seal the water outlet pipe 11 and the road surface; and the water outlet pipe 11 and the water storage cylinder 8 are connected through the blocking mechanism.

[0055] Afterwards, the first protruding column 503 slides in the vertical groove 302, during which the sealing mechanism and the blocking mechanism remain unchanged; and the piston 7 drives the detection liquid to flow toward the road surface; to accelerate the flow rate of the detection liquid toward the road surface, it can increase the squeezing force of the detection liquid on the road surface, thereby improving the detection efficiency and avoiding the detection efficiency being reduced due to the low permeability coefficient of the road surface, resulting in a slow flow rate of the detection liquid; The pressure-supplying mechanism, the blocking mechanism and the sealing mechanism cooperate with each other and act synchronously to improve the detection efficiency and the accuracy of the detection result.

[0056] In another embodiment of the present invention, a second protruding column 1502 is slidably mounted on the rotating plate 15, a baffle 1503 is fixedly mounted on the second protruding column 1502, and a small spring 1504 fixedly connected to the rotating plate 15 is fixedly mounted on the baffle 1503; a flat groove 1601 and a fourth inclined groove 1602 that are slidably engaged with the second protruding column 1502 are provided on the connecting plate 16, and one end of the flat groove 1601 is connected to the lowermost end of the fourth inclined groove 1602.

[0057] Taking an embodiment combining all the features described in this application as an example, when in use, when the first raised column 503 slides in the vertical groove 302 to the connection between the vertical groove 302 and the second inclined groove 303, the sliding time of the first raised column 503 in the vertical groove 302 is recorded to derive the water permeability coefficient of the converted road surface.

[0058] During the rotation of the first protruding column 1501, the second protruding column 1502 will rotate synchronously; during the contact between the first protruding column 1501 and the rotating rod 1802, the second protruding column 1502 will slide in the flat groove 1601, and the relative distance between the second protruding column 1502 and the rotating plate 15 does not change during this process.

[0059] During the process that the first protruding column 1501 contacts with the rotating rod 1802 and drives the rotating rod 1802 to rotate synchronously, the second protruding column 1502 slides in the fourth inclined groove 1602; through the mutual sliding contact with the fourth inclined groove 1602, the second protruding column 1502 will drive the baffle 1503 to approach the rotating plate 15 to compress the small spring 1504. At this time, the second protruding column 1502 slides on the rotating plate 15 and gradually approaches the valve sleeve 17; when the rotating plate 15 stops rotating, the water outlet pipe 11 is connected with the water storage cylinder 8, and at this time, the first protruding column 1501 and the second protruding column 1502 are distributed on both sides of the rotating rod 1802.

[0060] When the first protruding column 503 rotates in the second inclined groove 303, the rotating shaft 3 rotates in the opposite direction, and at this time, the sealing mechanism and the blocking mechanism move synchronously in the opposite direction.

[0061] When the blocking mechanism moves in the reverse direction, the rotating plate 15 rotates in the reverse direction. At this time, the second protruding column 1502 will conflict with the rotating rod 1802 and drive the rotating rod 1802 to rotate in the reverse direction, so as to drive the spherical stopper 18 to rotate in the reverse direction, so as to gradually reduce the conduction area between the water outlet pipe 11 and the water storage cylinder 8; and the second protruding column 1502 also slides toward the flat groove 1601 in the fourth inclined groove 1602 at the same time. Under the elastic force of the small spring 1504, the baffle 1503 will gradually move away from the rotating plate 15, so that the second protruding column 1502 gradually moves away from the valve sleeve 17, that is, the contact area between the second protruding column 1502 and the rotating rod 1802 gradually decreases; when the conduction area between the water outlet pipe 11 and the water storage cylinder 8 is zero, the second protruding column 1502 enters the flat groove 1601, and the second protruding column 1502 is completely immersed in the rotating plate 15, that is, the rotating rod 1802 does not contact and cooperate with the second protruding column 1502. During this process, the second protruding column 901 slides in the third inclined groove 1001 in the opposite direction to drive the sliding sleeve 10 away from the road surface, thereby releasing the elastic force of the sealing spring 12 and reducing the deformation of the sealing ring 1301 .

[0062] Afterwards, the rotating plate 15 continues to rotate to complete the reset, and the sliding sleeve 10 continues to slide away from the road surface to drive the sealing ring 1301 to reset.

[0063] First, the water outlet pipe 11 and the water storage cylinder 8 are blocked, and then the sealing state of the water outlet pipe 11 with the road surface is released; to prevent the detection liquid from flowing from the connection gap to the surrounding area, causing waste of detection liquid; at the same time, it can also provide a more similar detection environment for subsequent re-inspections.

[0064] Afterwards, observe whether the first raised column 503 slides in the detection groove 304 to determine whether the conduction area between the water outlet pipe 11 of the device and the water storage cylinder 8 is zero; if the conduction area is zero, the first raised column 503 can no longer slide in the detection groove 304, and if the conduction area is not zero, the first raised column 503 can slide in the detection groove 304, and the accuracy of this detection result is not reliable.

[0065] In another embodiment of the present invention, the fourth inclined groove 1602 is inclined toward the rotating plate 15 .

[0066] Taking the embodiment combining all the features described in the present application as an example, when in use, the fourth inclined groove 1602 is inclined toward the rotating plate 15, and the groove wall of the fourth inclined groove 1602 gradually approaches the rotating plate 15. When the second protruding column 1502 slides in the fourth inclined groove 1602, the groove wall of the fourth inclined groove 1602 causes the second protruding column 1502 to rotate closer to or away from the valve sleeve 17.

[0067] In another embodiment of the present invention, a pedal 102 is rotatably mounted on the base 1 .

[0068] Taking the embodiment combining all the features described in the present application as an example, when in use, the pedal 102 is used to fix the base 1 so that its position is not easily shifted, so as to improve the accuracy of detection.

[0069] In another embodiment of the present invention, a pull ring 401 is fixedly mounted on one end of the sliding rod 4 away from the connecting plate 5 .

[0070] Taking the embodiment combining all the features described in the present application as an example, when in use, through the cooperation between the pull ring 401 and the pedal 102, the connecting plate 5 can be driven by the slide rod 4 to approach the fixed plate 2 to compress the pressure spring 6, so as to facilitate the use of the device.
