Railway bridge deck drain pipe hole blocking device

Abstract

This utility model belongs to the field of bridge construction technology, specifically a device for plugging holes in drainage pipes of railway bridge decks. It includes a baffle plate with a circular frame fixedly connected to one side. This process involves setting up the baffle plate, circular frame, fixing groove, connecting block, through groove, and inclined groove. In use, multiple grooves of the same length as the connecting block are evenly opened near the drainage pipe. The baffle plate is then placed on the upper side of the drainage pipe, allowing the circular frame to be inserted into the inside of the drainage pipe. Concrete of the same material as that used in bridge construction is then poured into the through groove and inclined groove until both are completely filled. After the concrete solidifies, it clamps the inclined groove, thus fixing the device. The baffle plate blocks the water flow, preventing water from entering the inside of the drainage pipe. A thicker steel plate can be used for the baffle plate; as long as the baffle plate is not penetrated, a seal is achieved. There is no need to worry about water seepage leading to seal failure after long-term use of the concrete, thus improving the stability of the device.

Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically a device for plugging holes in drainage pipes on railway bridge decks. Background Technology

[0002] During the construction of a new railway bridge deck, if there are plans for a new grade highway or railway line below the new line, the drainage pipes already embedded on the new bridge above the planned line need to be sealed.

[0003] Existing methods for plugging holes in railway bridge decks typically involve installing a reinforcing cage inside the drain pipe, injecting concrete (using the same materials as the bridge) into the drain pipe, and then waterproofing the hardened concrete. While this method can seal the drain pipe, the strength and durability of the concrete deteriorate over time, making the seal less tight and affecting the stability of the drain pipe sealing. Therefore, this paper proposes a device for plugging drain pipes on railway bridge decks to address these issues. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A plugging device for a drainage pipe on a railway bridge deck, comprising a baffle, a circular frame fixedly connected to one side of the baffle, a fixing groove formed on the surface of the baffle, a connecting block fixedly connected to the inner side of the fixing groove, a through groove formed on the surface of the connecting block, and an inclined groove formed on the surface of the connecting block, the inclined groove and the through groove communicating with each other; this step involves setting up a baffle, a circular frame, a fixing groove, a connecting block, a through groove, and an inclined groove. In use, multiple holes of the same length as the connecting blocks are evenly opened near the drainage pipe. The device is then constructed by placing a baffle on the upper side of the drain pipe, allowing the circular frame to be inserted into the drain pipe. Concrete, made from the same material as that used in bridge construction, is then poured into the through-channel and inclined channels until both are completely filled. After the concrete hardens, it secures the inclined channel, thus fixing the device in place. The baffle blocks the water flow, preventing it from entering the drain pipe. A thicker steel plate can be used for the baffle; as long as the baffle is not penetrated, a seal is achieved. There is no need to worry about water seepage leading to seal failure after long-term use, thus improving the stability of the device.

[0006] Preferably, a groove is provided on the inner side of the baffle, and a sealing ring is fixedly connected to the inner side of the groove. This step, by setting the groove and the sealing ring, and by placing the sealing ring on the inner side of the groove, ensures that when the baffle is placed on the ground, the sealing plate is not too thick, which would affect the baffle's tightness against the ground. Furthermore, because the sealing ring is made of rubber, when the baffle is pressed against the ground, the sealing ring deforms due to the pressure on the ground, making it fit the ground even better. This further blocks and seals the opening of the drain pipe, improving the sealing performance of the device.

[0007] Preferably, an expansion pad is fixedly connected to the outer side of the circular frame, and an air inlet pipe is connected to the inner side of the expansion pad. The sealing ring and baffle are both fixedly connected to the air inlet pipe. This step involves setting up an expansion pad and an air inlet pipe, both of which are supported by wear-resistant rubber material of a certain thickness. By injecting gas into the inner side of the air inlet pipe, the gas enters between the circular frame and the expansion pad, causing the expansion pad to expand and adhere tightly to the inner wall of the drain pipe. After the gas injection is completed, one end of the air inlet pipe is heat-sealed to close the air inlet pipe, preventing the injected gas from overflowing again. This further seals the inner wall of the drain pipe and the circular frame, further increasing the waterproof measures of the device and improving the sealing performance of the device during use.

[0008] Preferably, a rubber sleeve is fitted on the outer side of the air intake pipe, and a protrusion is fixedly connected to the inner side of the rubber sleeve. The protrusion and the air intake pipe are slidably connected. This step, by setting a wear-resistant rubber sleeve and a protrusion, allows the rubber sleeve to be fitted on the outer side of the air intake pipe after the gas injection is completed, so that the protrusion is inserted into the inner side of the air intake pipe. Then, the air intake pipe is heat-sealed, so that the rubber sleeve and the protrusion can be fused with the inner and outer sides of the air intake pipe through heat fusion, thereby making the seal of the air intake pipe more stable and improving the stability of the device.

[0009] Preferably, a fixed frame is fixedly connected to the outer side of the baffle, and a cover plate is slidably connected to the inner side of the fixed frame. This step, by setting the fixed frame and the cover plate, allows the air intake pipe to be shielded by placing the cover plate inside the fixed frame after the air intake pipe is heat-sealed. This prevents the part of the air intake pipe exposed outside the baffle from being worn due to contact with the external environment, thus reducing the likelihood of air leakage from the air intake pipe and improving the stability of the device.

[0010] Preferably, the inner side of the baffle is provided with a receiving groove, and a hanging plate is fixedly connected to the inner side of the receiving groove; this step, by setting the receiving groove and the hanging plate, allows the crane hook to pass through the hanging plate when the device is installed and disassembled, thereby facilitating the lifting and placement of the device and improving the convenience of loading and unloading the device.

[0011] The advantages of this utility model are: 1. This utility model, by setting up a baffle, a circular frame, a fixing groove, a connecting block, a through groove, and an inclined groove, is used by first evenly opening multiple grooves of the same length as the connecting block near the drain pipe, then placing the baffle on the upper side of the drain pipe so that the circular frame is inserted into the inside of the drain pipe, and then pouring concrete of the same material as that used in bridges into the through groove and the inclined groove until both are completely filled. After the concrete solidifies, the inclined groove is fixed by the concrete. The baffle blocks the water flow, preventing the water from entering the inside of the drain pipe. The baffle can be made of a relatively thick steel plate. As long as the baffle is not penetrated, the seal can be completed. There is no need to worry about water seepage after long-term use of the concrete causing the seal to fail, thus improving the stability of the device. 2. This utility model, by setting a groove and a sealing ring, with the sealing ring set inside the groove, ensures that when the baffle is placed on the ground, the sealing plate is not too thick, which would affect the baffle's tightness against the ground. Furthermore, because the sealing ring is made of rubber, when the baffle is pressed against the ground, the sealing ring deforms due to the pressure on the ground, making it fit the ground even better. This further blocks and seals the opening of the drain pipe, improving the sealing performance of the device. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0016] Specific implementation examples are given below.

[0017] Please see Figures 1 to 5 As shown, a device for plugging holes in a drainage pipe on a railway bridge deck includes a baffle 1. A circular frame 2 is fixedly connected to one side of the baffle 1. A fixing groove 3 is formed on the surface of the baffle 1. A connecting block 4 is fixedly connected to the inner side of the fixing groove 3. A through groove 5 and an inclined groove 6 are formed on the surface of the connecting block 4, and the inclined groove 6 and the through groove 5 are connected. This step involves setting up the baffle 1, circular frame 2, fixing groove 3, connecting block 4, through groove 5, and inclined groove 6. In use, multiple grooves of the same length as the connecting block 4 are evenly opened near the drainage pipe, and then the baffle 1 is... Placed on the upper side of the drain pipe, the circular frame 2 is inserted into the inside of the drain pipe. Then, concrete of the same material as that used in the bridge is poured into the through groove 5 and the inclined groove 6 until both are completely filled. After the concrete solidifies, the inclined groove 6 is fixed by the concrete. The baffle 1 blocks the water flow, preventing water from entering the inside of the drain pipe. The baffle 1 can be made of a thick steel plate. As long as the baffle 1 is not penetrated, the seal can be completed. There is no need to worry about water seepage after long-term use of the concrete causing the seal to fail, which improves the stability of the device.

[0018] Furthermore, such as Figure 1 As shown, a groove 7 is provided on the inner side of the baffle 1, and a sealing ring 8 is fixedly connected to the inner side of the groove 7. This step, by setting the groove 7 and the sealing ring 8, and by setting the sealing ring 8 on the inner side of the groove 7, makes it so that when the baffle 1 is placed on the ground, the sealing plate 9 is not too thick and will not affect the baffle 1's tightness to the ground. And because the sealing ring 8 is made of rubber, when the baffle 1 is pressed against the ground, the sealing ring 8 deforms due to the tightness to the ground, making it fit the ground better, thereby further blocking and sealing the opening of the drain pipe, improving the sealing performance of the device.

[0019] Furthermore, such as Figure 2 and Figure 5As shown, an expansion pad 9 is fixedly connected to the outer side of the circular frame 2, and an air inlet pipe 10 is connected to the inner side of the expansion pad 9. The sealing ring 8 and the baffle 1 are both fixedly connected to the air inlet pipe 10. This step involves setting up the expansion pad 9 and the air inlet pipe 10, both of which are supported by wear-resistant rubber material of a certain thickness. By injecting gas into the inner side of the air inlet pipe 10, the gas enters between the circular frame 2 and the expansion pad 9, causing the expansion pad 9 to expand and adhere tightly to the inner wall of the drain pipe. After the gas injection is completed, one end of the air inlet pipe 10 is sealed by heat fusion to close the air inlet pipe 10, so that the injected gas will not overflow again, thereby further sealing the inner wall of the drain pipe and the circular frame 2, further increasing the waterproof measures of the device, and improving the sealing performance of the device during use.

[0020] Furthermore, such as Figure 1 and Figure 4 As shown, a rubber sleeve 11 is fitted on the outer side of the air intake pipe 10, and a protrusion 12 is fixedly connected to the inner side of the rubber sleeve 11. The protrusion 12 and the air intake pipe 10 are slidably connected. This step, by setting the wear-resistant rubber sleeve 11 and the protrusion 12, allows the rubber sleeve 11 to be fitted on the outer side of the air intake pipe 10 after the gas injection is completed, so that the protrusion 12 is inserted into the inner side of the air intake pipe 10. Then, the air intake pipe 10 is heat-sealed, so that the rubber sleeve 11 and the protrusion 12 can be fused with the inner and outer sides of the air intake pipe 11 by heat fusion, thereby making the seal of the air intake pipe 10 more stable and improving the stability of the device.

[0021] Furthermore, such as Figure 1 and Figure 2 As shown, a fixed frame 13 is fixedly connected to the outer side of the baffle 1, and a cover plate 14 is slidably connected to the inner side of the fixed frame 13. This step, by setting the fixed frame 13 and the cover plate 14, allows the air intake pipe 10 to be shielded by placing the cover plate 14 inside the fixed frame 13 after the air intake pipe 10 is heat-sealed. This prevents the part of the air intake pipe 10 exposed outside the baffle 1 from being worn due to contact with the external environment, thus reducing the likelihood of air leakage from the air intake pipe 10 and improving the stability of the device.

[0022] Furthermore, such as Figure 1 As shown, the inner side of the baffle 1 is provided with a receiving groove 15, and a hanging plate 16 is fixedly connected to the inner side of the receiving groove 15. This step, by setting the receiving groove 15 and the hanging plate 16, allows the crane hook to pass through the hanging plate 16 when the device is installed and disassembled, thereby facilitating the lifting and placement of the device and improving the convenience of loading and unloading the device.

[0023] Working principle: During use, first, multiple grooves of the same length as connecting block 4 are evenly opened in the ground near the drain pipe. Then, baffle 1 is placed on the upper side of the drain pipe, and connecting block 4 is inserted into the multiple grooves, extending into the concrete ground. Circular frame 2 is inserted into the drain pipe. Then, concrete of the same material used in bridge construction is injected into the through groove 5 and inclined groove 6, ensuring the injected concrete contacts the concrete on the ground surface until both are completely filled. After the concrete hardens, it will connect and fix to the existing concrete on the ground. The device is fixed in position by securing the inclined groove 6 with concrete. Gas is injected into the inside of the air inlet pipe 10, and the gas enters between the circular frame 2 and the expansion pad 9, causing the expansion pad 9 to expand and adhere tightly to the inner wall of the drain pipe. After the gas injection is completed, one end of the air inlet pipe 10 is sealed by heat fusion to prevent the injected gas from overflowing again. Then, the baffle 14 is placed inside the fixed frame 13 to seal the air inlet pipe 10. The water flow is blocked by the baffle 1, preventing the water from entering the inside of the drain pipe.
