Description

Technical Field

[0001] This application relates to the field of seepage detection technology, and in particular to a bridge seepage prevention detection device for bridge engineering. Background Technology

[0002] Currently, bridge seepage prevention testing is an important part of bridge engineering acceptance. It is generally carried out by manually operating a seepage meter to conduct equidistant sampling tests on the bridge surface.

[0003] The existing permeability meter mainly consists of a permeability ring, measuring equipment, counterweight, and water. By placing the permeability ring on the asphalt bridge surface and ensuring its airtightness, a certain amount of water is injected into the permeability ring, and timing is started to record the drop in water level in order to calculate the water permeability.

[0004] When using a permeability meter for testing, firstly, an equivalent mark needs to be drawn on the bridge surface according to the shape and size of the bottom of the permeability meter. Then, waterproof material is placed within the mark. The waterproof material is usually silicone sealant. During the application of silicone sealant, it is necessary to ensure the uniformity and accuracy of the applied area.

[0005] The existing technical solutions mentioned above have the following drawbacks: In order to ensure the uniformity and accuracy of the area after applying the glass sealant, the staff needs to spend a long time applying and correcting it, and observe to determine whether the seepage meter can be placed. Only then can the seepage meter be placed on the glass sealant and the valve be opened to start the waterproofing test. Each operation takes a long time and requires multiple operations on the bridge surface. The operation is highly repetitive and complicated, and the sealing performance of the bottom of the seepage meter cannot be guaranteed. Summary of the Invention

[0006] This application provides a bridge seepage detection device for bridge engineering in order to simplify the seepage detection process and improve sealing performance.

[0007] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0008] A bridge seepage detection device for bridge engineering includes a base plate, a seepage cavity is formed in the middle of the bottom surface of the base plate, a glue storage ring groove for storing glass glue is formed on the upper surface of the base plate and a ring cover for covering the glue storage ring groove is detachably provided, and an installation groove is also formed on the lower surface of the base plate. The installation groove and the glue storage ring groove are connected by a through hole. The inner diameter of the installation groove is larger than the outer diameter of the seepage cavity and is spaced apart from the seepage cavity.

[0009] The detection device also includes a glue dispensing component installed in the base plate, a second sealing ring fixedly installed on the outer edge of the bottom surface of the base plate, and a third sealing ring fixedly installed on the lower edge of the inner wall of the seepage cavity. The bottom of the second sealing ring and the third sealing ring are both lower than the bottom surface of the base plate.

[0010] The dispensing assembly includes an annular push plate slidably disposed within a glue storage ring groove, a first sealing ring sleeved on the inner and outer walls of the annular push plate, a connecting rod movably inserted into a through hole and fixedly connected at its upper end to the annular push plate, a mounting ring fixedly connected to the lower end of the connecting rod and movably disposed within a mounting groove, a first washer fixedly connected to the lower bottom surface of the mounting ring and spaced apart from the third sealing ring, and a second washer fixedly connected to the lower bottom surface of the mounting ring and located between the first washer and the second sealing ring. The second washer is spaced apart from the second sealing ring and the first washer. A glue discharge hole is provided in the base plate, with both ends connecting the bottom surface of the base plate to the glue storage ring groove. The lower ends of the glue discharge holes connect the second sealing ring and the second washer, as well as the third sealing ring and the first washer. When the mounting ring is fully inserted into the mounting groove, the space between the second sealing ring and the second washer, as well as the space between the third sealing ring and the first washer, is filled with silicone sealant.

[0011] By adopting the above technical solution, after placing a counterweight on the base plate, the counterweight applies pressure to the base plate, causing the glue dispensing component to automatically dispense glue onto the bottom surface of the base plate. The glue flows between the glue dispensing component and the second and third sealing rings and adheres to the bridge road surface. This allows for two sealing treatments between the base plate and the bridge road surface in one step, without the need to apply glue to the bridge road surface in advance. This effectively simplifies the layout process of the testing device. At the same time, it allows the glass glue to follow the position of the base plate and accurately seal between the base plate and the bridge road surface. Combined with the two sealing treatments, it can also significantly improve the sealing performance.

[0012] Optionally, the end faces of the second and third sealing rings located below the bottom surface of the base plate are in the form of right-angled triangles. The right-angled outer wall of the right-angled triangle is flush with the outer wall of the base plate and the inner wall of the seepage cavity, and the hypotenuses of the right-angled triangle are arranged opposite each other.

[0013] By adopting the above technical solution, the flexibility of the sealing ring is effectively improved. During the pressure process of the base plate, the sealing ring with a right-angled triangular cross section can deform more smoothly, while also restricting the glass glue.

[0014] Optionally, the third sealing ring has an overflow hole and a sealing plug for closing the overflow hole.

[0015] By adopting the above technical solution, the sealing plug can be removed, and the overflow hole can connect the inside and outside of the third sealing ring, thereby increasing the glue dispensing speed. When the glass glue flows out from the overflow hole, it can also be concluded that the cavity is almost full of glass glue, thus enabling accurate judgment on the glue dispensing and sealing work of the detection device.

[0016] Optionally, a plurality of annular wing plates are integrally formed and spaced apart on the first sealing ring, and the annular wing plates are located outside the annular push plate.

[0017] By adopting the above technical solution, the multiple spaced annular wing plates can improve the flexibility of the outside of the first sealing ring, so as not to hinder the annular pusher plate from pushing the glass glue, and also to improve the sealing performance between the annular pusher plate and the inner wall of the glue storage ring groove.

[0018] Optionally, a return spring is fitted on the connecting rod, with its two ends abutting against the bottom of the mounting groove and the mounting ring, respectively.

[0019] By adopting the above technical solution, after the bridge pavement has completed the water seepage test, the compressed return spring has a strong tendency to unfold, which makes it easier to pull the annular push plate to the bottom of the rubber storage ring groove.

[0020] Optionally, the inner wall of the glue storage ring groove is provided with a groove for embedding the ring cover, and a glue discharge groove is provided on the bottom surface of the groove. The two ends of the glue discharge groove are respectively connected to the inner wall of the glue storage ring groove and the upper end of the glue discharge hole.

[0021] By adopting the above technical solution, the ring cover is located in the groove to protect the ring cover, and the glue discharge groove is opened at the bottom of the groove to facilitate the cleaning of the glue discharge groove and the glue discharge hole.

[0022] Optionally, a locking component is installed on the ring cover, and a lock hole is provided on the bottom surface of the groove for the locking component to be inserted and engaged.

[0023] By adopting the above technical solution, the ring cover can be quickly disassembled and assembled, which facilitates the filling of glue inside the glue storage ring groove.

[0024] Optionally, the locking assembly includes a rotating shaft movably inserted into the ring cover, a locking block fixed to the outer wall of the lower end of the rotating shaft, a locking spring sleeved on the rotating shaft and located on the upper part of the ring cover, and a mounting cap fixed to the upper end of the rotating shaft and abutting against the upper end of the locking spring.

[0025] The lock hole includes an insertion hole formed on the bottom surface of the groove for inserting the rotating shaft and the locking block, and a locking hole formed from the outer wall of the base plate and connected to the insertion hole. When the mounting cap compresses the locking spring, the locking block corresponds to the locking hole, and rotating the mounting cap allows the locking block to be engaged in the locking hole.

[0026] By adopting the above technical solution, pressing the mounting cap compresses the locking spring and rotates the locking block into the locking hole, which can quickly assemble the ring cover and the base plate. At the same time, the overall locking structure is simple, which is convenient for operators to operate and facilitates repeated operation.

[0027] Optionally, a sealing gasket adapted to the bottom of the groove is fixed to the ring cover.

[0028] By adopting the above technical solution, the sealing performance of the ring cover after sealing the rubber storage ring groove is improved.

[0029] Optionally, the lower end of the connecting rod has a threaded section machined on its outer wall, and the threaded section passes through the mounting ring;

[0030] A baffle is sleeved and fixed on the connecting rod and located at the upper end of the threaded section. The baffle is located at the lower end of the return spring, and a nut is threadedly connected to the threaded section.

[0031] By adopting the above technical solution, the mounting ring is connected to the connecting rod, which facilitates the disassembly and assembly of the mounting ring, and thus facilitates the cleaning of the mounting groove and the glue storage ring groove.

[0032] In summary, this application has the following technical effects:

[0033] 1. By setting up a base plate, glue dispensing component, second sealing ring, and third sealing ring, the base plate and bridge pavement can be sealed twice in one go without applying glue to the bridge pavement in advance. This can effectively simplify the layout process of the testing device. At the same time, the glass glue can follow the position of the base plate to dispense glue and accurately seal the base plate and bridge pavement. With the two sealing processes, the sealing performance can be significantly improved.

[0034] 2. By setting the end face of the sealing ring to be a right-angled triangle, the flexibility of the sealing ring is effectively improved. During the pressure process of the base plate, the sealing ring with a right-angled triangle cross section can deform more smoothly, and at the same time, it can also restrict the glass glue.

[0035] 3. By setting an overflow hole and a sealing plug, the sealing plug can be removed. The overflow hole can connect the inside and outside of the third sealing ring, increasing the glue dispensing speed. When the glass glue flows out from the overflow hole, it can be concluded that the cavity is almost full of glass glue, thus enabling accurate judgment on the glue dispensing and sealing work of the detection device.

Detailed Implementation

[0042] The present application will be further described in detail below with reference to the accompanying drawings.

[0043] This application discloses a bridge seepage prevention detection device in bridge engineering, referring to... Figure 1 The detection device includes a circular and horizontally arranged base plate 1, three vertically arranged and equally angled connecting rods 2 on the upper surface of the base plate 1, a circular and horizontally connected top plate 3, a connecting pipe 4 fixed at both ends to the base plate 1 and the top plate 3 and located between the three connecting rods 2, two counterweights 5 that can be placed on the base plate 1, a glue dispensing assembly 6 set on the lower surface of the base plate 1, and a second sealing ring 7 and a third sealing ring 8 set on the lower surface of the base plate 1. The bottoms of the second sealing ring 7 and the third sealing ring 8 are both lower than the lower surface of the base plate 1, and the glue dispensing assembly 6 is located between the second sealing ring 7 and the third sealing ring 8.

[0044] After placing the counterweight 5 on the base plate 1, the counterweight 5 applies pressure to the base plate 1, causing the glue dispensing component 6 to dispense glue onto the bottom surface of the base plate 1. The glue flows between the glue dispensing component 6 and the second sealing ring 7 and the third sealing ring 8 and adheres to the bridge road surface. This allows for two sealing treatments between the base plate 1 and the bridge road surface in one operation, without the need to apply glue to the bridge road surface in advance. This effectively simplifies the setup process of the testing device. At the same time, it allows the glass glue to follow the position of the base plate 1 and dispense glue to accurately seal between the base plate 1 and the bridge road surface. Combined with the two sealing treatments, it can also significantly improve the sealing performance.

[0045] Reference Figure 1A circular seepage cavity 11 is formed on the bottom surface of the base plate 1, and the seepage cavity 11 is connected to the lower end of the connecting pipe 4. A circular glue storage ring groove 12 concentric with the base plate 1 is formed on the upper surface of the base plate 1, and an embedded groove 121 is formed on the side wall of the groove opening of the glue storage ring groove 12. The upper plate of the base plate 1, the embedded groove 121 and the glue storage ring groove 12 are formed in a stepped manner. Multiple glue discharge grooves 122 are formed at equal angles on the bottom surface of the embedded groove 121, and one end of the glue discharge groove 122 is connected to the glue storage ring groove 12. A glue discharge hole 123 is formed on the lower surface of the base plate 1 at the end of the glue discharge groove 122 away from the glue storage ring groove 12. The two ends of the glue discharge hole 123 are connected to the glue discharge groove 122 and the lower surface of the base plate 1, respectively, and the end of the glue discharge hole 123 located on the lower surface of the base plate 1 is located between the glue discharge assembly and the second sealing ring 7 and between the glue discharge assembly and the third sealing ring 8.

[0046] Combination Figure 2 and Figure 3 A ring cover 13 for covering the glue storage ring groove 12 is detachably provided in the groove 121. The inner diameter of the ring cover 13 is larger than the diameter of the top plate 3, so that the ring cover 13 can be easily removed through the top plate 3. A ring-shaped sealing gasket is bonded to the lower surface of the ring cover 13. The sealing gasket is consistent with the shape of the ring cover 13, thereby improving the sealing performance of the ring cover 13 to the glue storage ring groove 12.

[0047] Combination Figure 3 and Figure 4 A locking assembly 14 is provided on the ring cover 13. The locking assembly 14 includes a vertical rotating shaft 141 that passes through the ring cover 13, a locking block 142 that is fixed to the lower side wall of the rotating shaft 141 and located below the sealing gasket, a locking spring 143 that is sleeved on the rotating shaft 141 and located on the upper surface of the ring cover 13, and a mounting cap 144 that is fixed to the upper end of the rotating shaft 141 and is hollow inside. When the locking spring 143 is compressed, it can be completely located inside the mounting cap 144. At this time, the bottom of the mounting cap 144 abuts against the upper surface of the ring cover 13.

[0048] Reference Figure 3A locking hole 15 is provided on the base plate 1 to cooperate with the locking assembly 14. The locking hole 15 includes an insertion hole 151 and a snap-fit ​​hole 152, which are located at the bottom of the groove 121 and between the two glue discharge grooves 122. The shapes of the rotating shaft 141 and the snap-fit ​​block 142 are adapted to the insertion hole 151 and can be inserted into the insertion hole 151 at the same time. The insertion hole 151 and the snap-fit ​​hole 152 are offset and have an included angle. The two ends of the snap-fit ​​hole 152 are respectively connected to the insertion hole 151 and the outer wall of the base plate 1. The snap-fit ​​hole 152 is formed by machining the outer wall of the base plate 1 into the interior of the base plate 1. After the rotating shaft 141 and the snap-fit ​​block 142 are inserted into the insertion hole 151, the mounting cap 144 is rotated to make the snap-fit ​​block 142 snap into the snap-fit ​​hole 152. The mounting cap 144 then presses down the locking spring 143 and abuts against the upper surface of the ring cover 13, thereby connecting the ring cover 13 to the base plate 1 and sealing the glue storage ring groove 12. When it is necessary to add silicone sealant to the sealant storage ring groove 12, simply unscrew the mounting cap 144 to remove the ring cover 13. The operation is simple and convenient.

[0049] An exhaust valve 16, which connects to the seepage chamber 11, is also installed on the upper surface of the base plate 1.

[0050] The lower end of the connecting rod 2 is machined into a threaded section 631 and is threadedly connected to the upper surface of the base plate 1. The upper end of the connecting rod 2 is integrally formed with an end cap. The section of the connecting rod 2 near the end cap is machined with threads. After the lower end of the connecting rod 2 passes through the top plate 3, a connecting nut is screwed on. The connecting nut and the end cap clamp the top plate 3 and complete the connection between the base plate 1 and the top plate 3.

[0051] Reference Figure 2 A measuring cylinder 31 is vertically installed at the center of the top plate 3. The lower end of the measuring cylinder 31 is fixed to the top plate 3 and connected to the upper end of the connecting pipe 4. A valve 41 and a flow meter 42 are installed on the connecting pipe 4, with the flow meter 42 located between the valve 41 and the top plate 3. After the valve 41 is opened, the water in the measuring cylinder 31 can flow into the seepage chamber 11 through the connecting pipe 4. Before filling the seepage chamber 11 with water, the air vent valve 16 is opened. After the water flows out of the air vent valve 16, the air vent valve 16 is closed, thereby ensuring that the seepage chamber 11 is completely filled with water.

[0052] There are two counterweights 5. The counterweights 5 are semi-circular plates with V-shaped clearance grooves. When the two counterweights 5 are placed on the base plate 1 at the same time, the three connecting rods 2 are respectively located in the clearance grooves on the two counterweights 5.

[0053] Reference Figure 3 An annular mounting groove 17 for mounting the glue dispensing component 6 is provided on the lower surface of the base plate 1. The width of the groove opening of the mounting groove 17 is smaller than the width of the groove opening of the glue storage ring groove 12, and the mounting groove 17 and the glue storage ring groove 12 are spaced apart. A through hole connecting the two is provided inside the base plate 1 between the mounting groove 17 and the glue storage ring groove 12.

[0054] Combination Figure 3 and Figure 5 The dispensing assembly 6 includes an annular push plate 61 disposed in the glue storage ring groove 12, a first sealing ring 62 respectively installed on the inner and outer walls of the annular push plate 61 and in contact with the inner wall of the glue storage ring groove 12, a connecting rod 63 passing through the through hole and fixed at its upper end to the lower plate surface of the annular push plate 61, a return spring 64 sleeved on the push rod and located in the mounting groove 17, a mounting ring 65 fixed to the lower end of the connecting rod 63 and slidably disposed in the mounting groove 17, and a first washer 66 and a second washer 67 concentrically bonded to the side of the mounting ring 65 away from the base plate 1 and spaced apart from each other. The inner diameter of the first washer 66 is larger than the outer diameter of the second washer 67. The outer diameter of the first washer 66 is the same as the outer diameter of the mounting ring 65 and their outer walls are flush. The inner diameter of the second washer 67 is the same as the inner diameter of the mounting ring 65 and their inner walls are flush. The two discharge holes 123 are respectively connected to the space between the second sealing ring 7, the base plate 1 and the second gasket 67 and the space between the first sealing ring 62, the base plate 1 and the second gasket 67, so as to perform double-layer sealing treatment on the base plate 1 and the bridge road surface at the same time.

[0055] Reference Figure 5 The annular push plate 61 has a slot 611 on its side wall for installing the first sealing ring 62. After the first sealing ring 62 is inserted into the slot 611, the outer part of the first sealing ring 62 is outside the opening of the slot 611. The portion of the first sealing ring 62 outside the slot 611 is machined with spaced annular wing plates 621 along the thickness direction of the first sealing ring 62. The spaced annular wing plates 621 can improve the flexibility of the first sealing ring 62 and effectively improve the sealing performance of the first sealing ring 62 between the annular push plate 61 and the wall of the glue storage ring groove 12.

[0056] The upper end of the connecting rod 63 is fixedly connected to the annular push plate 61. A threaded section 631 is machined on the outer wall of the connecting rod 63 near its lower end. A baffle 632 is sleeved and fixed on the connecting rod 63 above the threaded section 631, and the baffle 632 abuts against the upper surface of the mounting ring 65. The lower end of the connecting rod 63 passes through the mounting ring 65. A countersunk hole is opened on the lower surface of the mounting ring 65, located between the first washer 66 and the second washer 67. The lower end of the connecting rod 63 is located in the countersunk hole and a nut 633 is screwed on. The nut 633 is located in the countersunk hole and its lower surface is flush with the lower surface of the mounting ring 65.

[0057] When the counterweight 5 is placed on the base plate 1, the base plate 1 is pressed down and moves downward, causing the annular push plate 61 to move upward relative to the glue storage ring groove 12. This allows the glass glue filled in the glue storage ring groove 12 to flow into the space between the gasket and the sealing ring through the glue discharge groove 122 and the glue discharge hole 123. When the space between the gasket and the sealing ring is completely filled with glass glue, the lower surface of the gasket is flush with the lower surface of the sealing ring.

[0058] Reference Figure 3 Grooves are machined into the outer and inner edges of the base plate 1 near the lower surface. A first connecting ring 71 is integrally formed on the second sealing ring 7, and a second connecting ring 81 is integrally formed on the third sealing ring 8. The first connecting ring 71 and the second connecting ring 81 are respectively adapted to the grooves and can be locked in the grooves. The second sealing ring 7 and the third sealing ring 8 can be installed on the inner and outer walls of the base plate 1 respectively by screws, bolts and other connecting parts. The end faces of the main bodies of the first sealing ring 62 and the second sealing ring 7 are both right-angled triangles, and the hypotenuses of the right-angled triangles are arranged opposite each other, thereby effectively improving the flexibility of the sealing rings. During the pressing of the counterweight block 5, the sealing ring with a right-angled triangle cross section can deform more smoothly, and at the same time, it can also restrict the glass glue.

[0059] Reference Figure 3 An overflow hole 82 is provided on the side wall of the third sealing ring 8, with its two ends connecting the right-angled outer wall and the inclined inner wall of the third sealing ring 8, respectively. The overflow hole 82 is located near the second connecting ring 81, and a sealing plug 83 is threaded into the overflow hole 82. Before the adhesive dispensing assembly 6 squeezes the sealant into the cavity between the sealing ring, the bottom surface of the base plate 1, and the gasket, the sealing plug 83 is removed. The overflow hole 82 can connect the inside and outside of the third sealing ring 8, increasing the dispensing speed. When the glass glue flows out from the overflow hole 82, it can be concluded that the cavity is almost full of glass glue, thus enabling accurate judgment of the dispensing and sealing work of the detection device. The second sealing ring 7 does not have an overflow hole 82 or a sealing plug 83. Since there will be gaps between the second sealing ring 7 and the second gasket 67 during contact with the bridge road surface, they cannot be completely sealed. This ensures that the glass glue can smoothly enter the cavity formed between the second sealing ring 7, the bottom surface of the base plate 1, and the second gasket 67, so as to achieve the purpose of forming a double-layer seal between the base plate 1 and the bridge road surface.

[0060] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
