Description

Technical Field

[0001] The present application relates to the field of bridge expansion joint anti-leakage technology, and in particular to an expansion joint anti-leakage water drainage device. Background Art

[0002] Bridge expansion joints refer to a structural joint set at an appropriate position along the bridge or in the direction of the bridge construction joint to prevent cracks or damage to the bridge components due to climate and temperature changes. The expansion joint divides the bridge components above the foundation into two independent parts, allowing the bridge to expand and contract horizontally along the length.

[0003] Rubber strips are usually installed in the expansion joints of bridges to prevent dirt from falling. They also block rainwater and divert water flow to a certain extent to prevent rainwater from invading the expansion joints and corroding the bridge structure. However, after the bridge is put into use, the traffic will make it more difficult for the construction unit to maintain the rubber strips, resulting in a short service life of the rubber strips, which cannot play a long-term role. Eventually, they will be damaged and rainwater and debris will directly penetrate into them, which will aggravate the corrosion of the connection between the box girder and the main beam. It is usually necessary to install a drainage device under the waterproof strip to divert the rainwater out.

[0004] However, the existing drainage device is usually fixed in the expansion joint with bolts. Due to the small operating space in the expansion joint and the need to shorten the working time as much as possible and reduce the impact on the normal traffic of the bridge, the disassembly, assembly and maintenance of the drainage device is difficult. Utility Model Content

[0005] In order to facilitate the disassembly, assembly and maintenance of a larger drainage device, the present application provides an expansion joint anti-leakage drainage device.

[0006] The present application provides an expansion joint anti-leakage drainage device that adopts the following technical solution:

[0007] A drainage device for preventing water leakage in an expansion joint comprises a bridge body and a drainage pipe, wherein the bridge body is provided with an expansion joint, the drainage pipe is installed on the bridge body, and further comprises a mounting seat and an arc-shaped guide plate, a bridge mounting groove is provided on the inner side wall of the expansion joint, the mounting seat is installed in the bridge mounting groove, a mounting seat plug-in groove is provided on the mounting seat, a plug-in plate is provided on the arc-shaped guide plate corresponding to the mounting seat plug-in groove, a plug-in rod is slidably connected to the mounting seat, the plug-in rod can pass through the plug-in plate to connect the arc-shaped guide plate with the mounting seat, and the arc-shaped guide plate is connected to the drainage pipe.

[0008] By adopting the above technical solution, the plug plate provided on the arc guide plate is inserted into the plug groove of the mounting seat, and then the plug rod is moved relative to the mounting seat, and the plug rod passes through the plug plate setting, thereby fixing the arc guide plate on the mounting seat. When the arc guide plate and the mounting seat need to be disassembled and repaired, the positioning rod can be pulled out, thereby quickly releasing the connection between the arc guide plate and the mounting seat, and the arc guide plate and the mounting seat can be repaired, which is beneficial to improving the efficiency of disassembly and maintenance of the drainage device.

[0009] In a specific possible implementation scheme, it also includes a sealing seat, which is installed in the bridge mounting groove. A sealing seat mounting groove is opened on the sealing seat. The mounting seat is slidably connected in the sealing seat mounting groove, and the side wall of the mounting seat abuts against the inner wall of the sealing seat mounting groove.

[0010] By adopting the above technical solution, the mounting seat is slidably connected in the sealing seat mounting groove, and the mounting seat is abutted against the sealing seat, thereby achieving sealing of the mounting seat and preventing rainwater from penetrating from the connection between the sealing seat and the inner wall of the expansion joint.

[0011] In a specific feasible implementation scheme, it also includes a limit buffer structure, which includes a limit rod, a roller, a positioning rod and a positioning block, wherein a cavity is opened in the mounting seat, and a mounting seat mounting groove is arranged on the mounting seat, one end of the sliding rod is arranged in the cavity, and the other end of the sliding rod penetrates the side wall of the mounting seat and extends into the mounting seat mounting groove and is rotatably connected to the roller, the inner side wall of the sealing seat mounting groove is provided with a sliding groove, and the roller can slide in the sliding groove, one end of the positioning rod is arranged in the cavity, and the other end of the positioning rod penetrates the side wall of the mounting seat, the positioning block is arranged in the cavity and fixedly connected to the positioning rod, the positioning block is inclinedly arranged adjacent to the side wall of one side of the limit rod, and the shape of one end of the limit rod adjacent to the positioning block corresponds to the inclined side wall of the positioning block, and the positioning block is used to push the limit rod to move out of the cavity.

[0012] By adopting the above technical solution, the side wall of the positioning block adjacent to the fixed limit rod is inclined, and the shape of the limit rod adjacent to one end of the positioning block is correspondingly set, so that the positioning block is driven by the positioning rod, and the inclined surface of the positioning block squeezes the inclined surface of the limit rod. As the positioning block moves, the limit rod is gradually pushed out of the cavity, thereby slidingly connected in the slide groove. When the bridge body is deformed horizontally due to thermal expansion and contraction, the roller slides in the slide groove to play a buffering role, thereby avoiding damage to the mounting seat and the arc guide plate.

[0013] In a specific possible implementation scheme, two of the limit rods and two of the rollers are provided, the two limit rods are arranged opposite to each other and move in opposite directions, and two of the mounting seat mounting grooves and two of the sliding grooves are provided correspondingly.

[0014] By adopting the above technical solution and setting two rollers, on the one hand, the stability of limiting the mounting seat on the sealing seat can be improved, and on the other hand, the friction between the mounting seat and the sealing seat can be reduced, thereby improving the smoothness and stability of the movement of the mounting seat.

[0015] In a specific possible implementation manner, a return spring is further included, one end of the return spring is fixedly connected to the inner wall of the cavity, and the other end of the return spring is fixedly connected to the limiting rod.

[0016] By adopting the above technical solution, when the mounting seat needs to be disassembled and overhauled, the positioning rod drives the positioning block in the reverse direction to release the support of the positioning block on the limit rod. Under the action of the reset spring, the limit rod moves into the cavity, thereby causing the roller to shrink into the mounting groove of the mounting seat, and the mounting seat can be removed, thereby improving the efficiency of disassembly and overhaul of the mounting seat.

[0017] In a specific possible implementation scheme, a protective net is installed on the arc-shaped guide plate, and a plurality of water holes are opened on the protective net.

[0018] By adopting the above technical solution, the water holes on the protective net can allow rainwater to smoothly enter the arc guide plate for diversion. At the same time, the protective net can block dirt and prevent dirt from entering the arc guide plate and accelerating the corrosion of the arc guide plate.

[0019] In a specific possible implementation scheme, the bridge mounting groove is arranged obliquely, and the lowest end of the arc-shaped guide plate is connected to the drainage pipe.

[0020] By adopting the above technical solution, the bridge installation groove is tilted, so that the arc guide plate is tilted, and rainwater flows into the drain pipe along the arc guide plate under the influence of gravity, which is beneficial to the drainage of rainwater.

[0021] In a specific feasible implementation scheme, the arc guide plate is configured as a "V"-shaped plate, the bridge mounting groove and the mounting seat are configured to correspond to the shape of the arc guide plate, and both ends of the arc guide plate are respectively connected to the drainage pipe.

[0022] By adopting the above technical solution, the arc guide plate adopts a "V"-shaped plate setting. When the amount of rainwater is too large, the rainwater can be diverted to both ends, thereby speeding up the diversion of rainwater and avoiding damage to the arc guide plate due to excessive accumulation of rainwater due to unilateral diversion.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Insert the plug plate on the arc guide plate into the plug slot of the mounting seat, and then move the plug rod relative to the mounting seat. The plug rod passes through the plug plate, so that the arc guide plate is fixed on the mounting seat. When the arc guide plate and the mounting seat need to be disassembled and repaired, the positioning rod can be pulled out, so as to quickly release the connection between the arc guide plate and the mounting seat, and the arc guide plate and the mounting seat can be repaired, which is conducive to improving the efficiency of disassembly and repair of the drainage device;

[0025] 2. The side wall of the positioning block adjacent to the fixed limit rod is inclined, and the shape of the limit rod adjacent to one end of the positioning block is correspondingly set, so that the positioning block is driven by the positioning rod, and the inclined surface of the positioning block squeezes the inclined surface of the limit rod. As the positioning block moves, the limit rod is gradually pushed out of the cavity, thereby slidingly connected in the slide groove. When the bridge body is deformed in the horizontal direction due to thermal expansion and contraction, the roller slides in the slide groove to play a buffering role, thereby avoiding damage to the mounting seat and the arc guide plate;

[0026] 3. The arc guide plate adopts a "V"-shaped plate setting. When the amount of rainwater is too large, it can divert the rainwater to both ends, thereby speeding up the diversion of rainwater and avoiding damage to the arc guide plate due to excessive accumulation of rainwater due to unilateral diversion.

[0036] like Figure 1 and Figure 2 As shown, the anti-leakage drainage device of the expansion joint 11 includes a bridge body 1, a drainage pipe 2, a mounting seat 3, an arc-shaped guide plate 5 and a sealing seat 4. An expansion joint 11 is provided on the bridge body 1, and a telescopic cover for covering the expansion joint 11 is installed on the bridge body 1, and a waterproof rubber strip is installed on the telescopic cover. A drain pipe 2 is installed on the bridge body 1 for discharging rainwater from the bridge deck, and bridge mounting grooves 12 are provided on the side walls on both sides of the expansion joint 11 below the telescopic cover. The bridge mounting grooves 12 are linearly inclined. Two mounting seats 3 and two sealing seats 4 are provided. The two sealing seats 4 are respectively installed in the bridge mounting grooves 12 on both sides. The sealing seat 4 is preferably set to a "U" shape. A sealing seat mounting groove 41 is provided on the sealing seat 4. The mounting seat 3 is slidably connected in the sealing seat mounting groove 41, and the side wall of the mounting seat 3 abuts against the inner wall of the sealing seat mounting groove 41 to achieve sealing. The two ends of the arc guide plate 5 are respectively detachably connected to the mounting seats 3 on both sides, and the arc guide plate 5 is linearly arranged corresponding to the sealing seat mounting groove 41, and the lower end of the arc guide plate 5 is connected to the drain pipe 2.

[0037] like Figure 3 and Figure 4As shown, in the embodiment of the present application, a limit buffer structure is also included, which includes a limit rod 61, a roller 62, a positioning rod 63, a positioning block 64 and a reset spring 65. Two limit rods 61, rollers 62 and reset springs 65 are provided. A cavity 31 is provided in the mounting seat 3. The mounting seat mounting grooves 32 are symmetrically provided on the side walls of the mounting seat 3 adjacent to the sealing seat 4. One end of the limit rod 61 is provided in the cavity 31, and the other end of the limit rod 61 penetrates the side wall of the mounting seat 3 and extends into the mounting seat mounting groove 32, and is rotatably connected to the roller 62. The limit rod 61 can move relative to the mounting seat 3, and the reset spring 65 is installed in the cavity 31. One end of the reset spring 65 is connected to the limit rod 6 1 is fixedly connected, the other end of the return spring 65 is fixedly connected to the inner wall of the cavity 31, and the return spring 65 is always in a compressed state. The positioning rod 63 is arranged perpendicular to the limiting rod 61, one end of the positioning rod 63 is arranged in the cavity 31, and the other end of the positioning rod 63 penetrates the side wall of the mounting seat 3, and the positioning rod 63 can move relative to the mounting seat 3. The positioning rod 63 is arranged in the cavity 31. One end of the positioning block 64 is fixedly connected to the positioning block 64, and the positioning block 64 is arranged in a "V" shape and inclined on one side of the limiting rod 61. The two positioning rods 63 are arranged on the inclined side wall of the positioning block 64 adjacent to one end. The sealing seat mounting groove 41 is provided with a slide groove 42 corresponding to the roller 62, and the slide groove 42 can be slidably connected in the slide groove 42;

[0038] Since the return spring 65 is always in a compressed state, the roller 62 is accommodated in the mounting groove 32 of the mounting seat, and the limit rod 61 pushes the positioning rod 63. The positioning rod 63 moves into the cavity 31 and drives the positioning block 64. The positioning block 64 tilts the side walls to squeeze the limit rods 61 on both sides and push the limit rods 61 to move out of the cavity 31. The spring is compressed and stores the force.

[0040] The implementation principle of the anti-leakage drainage device of the expansion joint 11 of the embodiment of the present application is as follows: the sealing seat 4 is installed in the bridge mounting groove 12, and the mounting seat 3 is inserted into the sealing seat mounting groove 41. Since the reset spring 65 is always in a compressed state, the roller 62 is received in the mounting seat mounting groove 32, and the limit rod 61 pushes the positioning rod 63, and the positioning rod 63 moves into the cavity 31 and drives the positioning block 64. The positioning block 64 tilts the side wall to squeeze the limit rods 61 on both sides and push the limit rods 61 to move out of the cavity 31. The reset spring 65 is compressed and stores the force. The roller 62 is slidably connected in the sealing seat mounting groove 41 with the movement of the limit rod 61. When the bridge body 1 is deformed due to thermal expansion and contraction, , the roller 62 slides relative to the slide groove 42, thereby avoiding damage to the mounting seat 3 and the arc-shaped guide plate 5 due to extrusion, facilitating the disassembly and maintenance of the mounting seat 3, and then the plug plates 51 at both ends of the arc-shaped guide plate 5 are plugged into the mounting seat plug grooves 33 at both ends, and the plug rod 7 slidably connected to the mounting seat 3 passes through the plug hole of the plug plate 51 to fix the arc-shaped guide plate 5 with the mounting seat 3.
