Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge drainage, in particular to a bridge expansion joint drainage structure. Background Art
[0002] Bridge expansion joints are typically installed between beam ends, between beam ends and abutments, or at hinged joints to accommodate bridge deck deformation. These joints must be able to expand and contract freely in both directions parallel and perpendicular to the bridge axis, be strong and reliable, and operate smoothly with no jerking or noise when vehicles pass over them. They must also prevent water, debris, and soil from seeping in and blocking the bridge. This is achieved through waterproof strips, but with age, these strips can age and become damaged. Once damaged, these strips lose their waterproofing effectiveness, allowing water to penetrate the joint and corrode the bridge bearings, shortening their service life. In order to solve the above technical problems, a water collection trough is set under the expansion joint to collect water passing through the expansion joint. One side of the water collection trough is fixed on the bottom surface of the beam end on one side of the expansion joint, and the other side is slidably connected to the bottom surface of the beam end on the other side of the expansion joint to ensure that the water collection trough can adapt to the expansion and contraction of the expansion joint. A drain pipe is fixedly connected to the bottom of the water collection trough, and the other end of the drain pipe is connected to a water collection well. The drain pipe introduces the water in the water collection trough into the water collection well for treatment. However, there is a problem with such a structure. One side of the water collection trough is fixed on the end of the beam. When the beam expands and contracts, the water collection trough moves with it. However, the water collection trough and the drain pipe are fixedly connected, which will inevitably lead to damage to the water collection trough, damage to the drain pipe and / or damage to the connection between the water collection trough and the drain pipe, resulting in water collection failure. Utility Model Content
[0003] In view of this, the purpose of the present invention is to provide a bridge expansion joint drainage structure to solve the technical problem that the existing expansion joint drainage structure may cause damage to the sump, damage to the drainage pipe and / or damage to the connection between the sump and the drainage pipe.
[0004] The purpose of this utility model is achieved through the following technical solutions:
[0005] A bridge expansion joint drainage structure includes a water collection trough, which is arranged in parallel with the expansion joint.

Horizontal plug interfaces are respectively provided on both sides of the bottom of the water collection trough, and support plates are movably inserted in the plug interfaces on both sides of the water collection trough. The support plates on both sides of the water collection trough are respectively connected to the bottom of the beam ends on both sides of the expansion joint through connecting parts. The bottom of the water collection trough is connected to a vertical hard drainage pipe, and the drainage pipe is fixed to the bridge pier through a number of fixed structures arranged at intervals. The other end of the drainage pipe is connected to a water collection well.
[0006] Furthermore, the connecting member includes an inverted L-shaped connecting plate, the openings of the inverted L-shaped connecting plate on both sides of the water collection tank are opposite to each other, the inverted L-shaped connecting plate is fixed to the bottom of the beam end by expansion screws, and the inverted L-shaped connecting plate connects the end of the support plate away from the water collection tank.
[0007] Furthermore, the connecting member includes a first vertical plate and a second vertical plate, the first vertical plate is embedded in the beam end, the second vertical plate is connected to the first vertical plate by bolts, and the second vertical plate is connected to the end of the support plate away from the sump.
[0008] Furthermore, the fixing structure includes a semicircular hoop with connecting ears at both ends, and the connecting ears are fixed to the pier by expansion screws.
[0009] Furthermore, there are two drainage pipes, which are respectively located at the two ends of the water collection tank.

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention and are not intended to limit the scope of protection of the present invention.
[0020] like Figure 1 As shown, a bridge expansion joint drainage structure includes a long stainless steel water collection trough 1. The water collection trough 1 is arranged in parallel with the expansion joint, that is, the water collection trough 1 is equal to the length of the expansion joint. The two sides of the water collection trough 1 are respectively located below and close to the bottom of the beam ends 2 on both sides of the expansion joint. That is, the width of the water collection trough 1 is larger than the lower gap of the beam ends 2 on both sides of the expansion joint after contraction, so as to completely collect the water leaking from the expansion joint waterproof strip 3. The two ends of the bottom of the water collection trough 1 are respectively connected to a vertical hard drainage pipe 4. The drainage pipe 4 is attached to the bridge pier 5 and fixed to the bridge pier 5 through a number of fixed structures 6 arranged at intervals. The other end of the drainage pipe 4 is connected to a water collection well. The drainage pipe 4 introduces the water in the water collection trough 1 into the water collection well for treatment. The fixed structure 6 includes a semicircular hoop 7. The two ends of the semicircular hoop 7 are respectively provided with a connecting ear 8. The connecting ear 8 is fixed to the bridge pier 5 by an expansion screw. Horizontal plug-in sockets 9 are respectively provided on both sides of the bottom of the water collection tank 1 between the two drain pipes 4. The plug-in sockets 9 are long and arranged along the length direction of the water collection tank 1. Support plates 10 are movably inserted in the plug-in sockets 9 on both sides of the water collection tank 1. The support plates 10 on both sides of the water collection tank 1 are respectively connected to the bottom of the beam ends 2 on both sides of the expansion joint through connecting parts. The connecting parts are made of stainless steel. The depth of the plug-in sockets 9 must meet the requirement that the beams on both sides of the expansion joint do not interfere with the support plates 10 after extension. The water collection tank 1 is supported by the support plates 10. When the beams on both sides of the expansion joint are extended or contracted, the water collection tank 1 maintains its position due to the pulling action of the drain pipe 4. The position of the support plate 10 changes in the plug-in sockets 9, so that the water collection tank 1 can adapt to the expansion and contraction of the beams on both sides of the expansion joint without damaging the water collection tank 1, the drain pipe 4 and / or the connection between the water collection tank 1 and the drain pipe 4. The connecting piece includes an inverted L-shaped connecting plate 11. The openings of the inverted L-shaped connecting plate 11 on both sides of the water collection tank 1 are opposite to each other. The inverted L-shaped connecting plate 11 is fixed to the bottom of the beam end 2 by expansion screws. The inverted L-shaped connecting plate 11 connects the end of the support plate 10 away from the water collection tank 1.
[0021] During construction, first fix a connector on the beam end 2 on one side of the expansion joint, insert the support plate 10 on the connector into the socket 9 on one side of the sump, insert the support plate 10 on the other connector into the socket 9 on the other side of the sump 1, and fix the other connector on the beam end 2 on the other side of the expansion joint. Then connect the drain pipe 4 to the sump 1, and connect the other end of the drain pipe 4 to the sump, and use several fixed structures to fix the drain pipe 4 on the pier 5.
[0022] There can be multiple sockets 9 on both sides of the water collection tank 1, and there can be multiple supporting plates 10 on both sides of the corresponding water collection tank 1. The structure of the connecting piece can also be other structures, such as including a first vertical plate and a second vertical plate, the first vertical plate is embedded in the beam end 2, the second vertical plate is connected to the first vertical plate by bolts, and the second vertical plate is connected to the end of the supporting plate 10 away from the water collection tank 1.
[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
