In one embodiment, as shown in fig. 1-3, a bridge drainage device comprises: the bridge deck comprises a supporting base body 100, a bridge deck body 200, a confluence mechanism 300 and a drainage assembly 400, wherein the bridge deck body 200 and the confluence mechanism 300 are arranged on the supporting base body 100, an expansion joint mechanism is arranged on the bridge deck body 200, the bridge deck body 200 and the confluence mechanism 300 are attached to each other, the confluence mechanism 300 has a first descending gradient from the surface of the bridge deck body 200, the drainage assembly 400 is communicated with the confluence mechanism 300, the communication position of the drainage assembly 400 and the confluence mechanism 300 is close to the expansion joint mechanism, and the confluence mechanism 300 reaches the drainage assembly 400 has a second descending gradient.

After the bridge drainage device is built, when the bridge deck body 200 is influenced by rainwater, a large amount of accumulated water can be generated near the expansion joint mechanism. At this time, since the surface of the deck body 200 has the first descending gradient to the surface of the merging mechanism 300, the accumulated water can flow from the surface of the deck body 200 toward the merging mechanism 300 by the first descending gradient and the gravity of the accumulated water itself, and the merging at the merging mechanism 300 is realized. The accumulated water in the confluence means 300 flows toward the drain assembly 400 by means of the second descending slope and the gravity of the accumulated water itself, and is finally discharged through the drain assembly 400. In this process, ponding can not get into expansion joint mechanism inside in a large number, but through mechanism 300 that converges to ponding back, the rethread drainage subassembly 400 is with ponding direct discharge. Therefore, the bridge drainage device greatly reduces the damage of the accumulated water on the bridge deck to the expansion joint mechanism, namely, the accumulated water is prevented from immersing into the inside of the bridge body through the expansion joint mechanism, and the durability of the bridge body is improved.

When the bridge deck body 200 and the support base 100 are installed, the compression resistance of the bridge deck body 200 is improved by installing the expansion joint mechanism. Specifically, the number of the confluence mechanisms 300 may be two, that is, two of the confluence mechanisms 300 are both mounted on the support substrate 100, and the two confluence mechanisms 300 (for convenience of description, the two confluence mechanisms 300 are divided into a first confluence mechanism and a second confluence mechanism) are respectively located at two sides of the bridge deck body 200. At this time, there is a first descending gradient from the surface of the deck body 200 to the first confluence means, and there is also a first descending gradient from the surface of the deck body 200 to the second confluence means. Thus, the surface of the deck body 200 is arched in cross-section (i.e. the surface of the deck body 200 is convex). At this time, accumulated water falling near the expansion joint mechanism or accumulated water on other parts of the surface of the bridge deck body 200 can flow to the first confluence mechanism or the second confluence mechanism, so that the confluence efficiency of the accumulated water is effectively improved.

In another embodiment, there is a first descending slope from the first side of the surface of the deck body 200 to the second side of the deck body 200, and the confluence mechanism 300 is attached to the second side of the deck body 200. When ponding appears on bridge floor body 200 or near expansion joint mechanism, ponding can flow to converging mechanism 300 under the effect of first decline slope and ponding self gravity and converge, avoids appearing a large amount of ponding near bridge floor body 200 surface and expansion joint.

Further, after the accumulated water is converged in the converging mechanism 300, the accumulated water can flow toward the drain assembly 400 under the direction of the second descending slope, and is finally discharged through the drain assembly 400. In this embodiment, the communication position between the drainage assembly 400 and the converging mechanism 300 is located near the expansion joint mechanism, on one hand, it can be ensured that accumulated water on the surface of the bridge deck body 200 (which refers to the surface corresponding to the expansion joint mechanism) can effectively flow into the converging mechanism 300, and on the other hand, the accumulated water is prevented from passing through the expansion joint mechanism when flowing in the converging mechanism 300, that is, the accumulated water in the converging mechanism 300 is prevented from entering the expansion joint mechanism.

As shown in fig. 1 to 3, in one embodiment, the confluence mechanism 300 includes a supporting pad 310, an auxiliary road deck 320 and a confluence part 330, the supporting pad 310 is mounted on the supporting substrate 100, the auxiliary road deck 320 is erected on the supporting pad 310, the confluence part 330 is mounted on the supporting substrate 100, a first side of the confluence part 330 is attached to the deck body 200, accumulated water on the deck body 200 enters the confluence part 330 through the first side of the confluence part 330, and a second side of the confluence part 330 is attached to the auxiliary road deck 320. The mechanism 300 that converges includes lip block 310, auxiliary road bridge floor 320 and the portion 330 that converges, lip block 310 is installed on the support base member 100, auxiliary road bridge floor 320 sets up on lip block 310, the portion 330 that converges is installed on the support base member 100, converge the first side of portion 330 with bridge floor body 200 laminates mutually, just ponding process on the bridge floor body 200 the first side of the portion 330 that converges gets into converge inside the portion 330, converge the second side of the portion 330 with auxiliary road bridge floor 320 laminates mutually. Specifically, the confluence part 330 is a stone or concrete block. After the deck body 200 is paved on the support substrate 100, the auxiliary road deck 320 is paved on the support substrate 100 through the supporting cushion blocks 310, and at this time, an installation gap is reserved between the auxiliary road deck 320 and the support substrate 100, and the installation gap can be used for corresponding embedding operation (for example, cable laying or maintenance space reservation, etc.).

Further, according to different bridge design requirements, after the installation of the auxiliary road bridge deck 320 is completed, a height difference exists between the auxiliary road bridge deck 320 and the bridge deck body 200, that is, the height of the auxiliary road bridge deck 320 is higher than that of the bridge deck body 200. At this time, when the accumulated water on the deck body 200 flows toward the merging mechanism 300, the accumulated water directly enters the merging portion 330 to be merged. In addition, the deck body 200 is often used as a road surface for motor vehicles to travel, and the auxiliary road deck 320 can be used for non-motor driving or pedestrian walking. At this time, the surface of the sub-tunnel bridge deck 320 may also be designed to have a certain descending slope, that is, when water accumulates on the sub-tunnel bridge deck 320, the accumulated water may flow to the side of the sub-tunnel bridge deck 320, for example, the accumulated water on the sub-tunnel bridge deck 320 may flow to the bridge deck body 200, and then flow into the confluence portion 330 through the bridge deck body 200 for confluence. Or the accumulated water on the auxiliary road deck 320 can directly flow to the outside of the bridge body.

As shown in fig. 1 to 3, in one embodiment, the junction 330 extends along a long side direction of the deck body 200 and a long side direction of the auxiliary deck 320, and a plurality of junction holes are spaced on a first side of the junction 330. In particular, the above-mentioned embodiment can effectively ensure that the accumulated water on the whole bridge deck body 200 can flow into the confluence part 330 for confluence, i.e. ensure the confluence effect of the confluence mechanism 300 on the accumulated water.

As shown in fig. 2 to 3, in one embodiment, the bridge drainage device further comprises a plurality of grate members 331. The plurality of grate members 331 are installed on the flow-merging holes in a one-to-one correspondence. Specifically, considering that the bridge deck body 200 tends to generate garbage or other foreign objects, the garbage (or other foreign objects) is driven to move towards the confluence mechanism 300 together when the accumulated water flows. At this time, the grate member 331 can prevent garbage from flowing into the collecting device 300 together with the accumulated water, i.e., prevent the garbage from being clogged in the collecting device 300.

As shown in fig. 2 and 3, in one embodiment, the bridge drainage device further includes a sealing member 332, the sealing member 332 is installed at the junction of the grate member 331 and the flow-merging hole along the circumferential direction of the grate member 331. Specifically, the sealing member 332 is a sealant or a sealing strip. Considering that the collecting hole of the collecting part 330 is opened at the side of the collecting part 330, when the comb member 331 is installed, the side (the side where the collecting hole is opened) corresponding to the collecting part 330 is opened with the recess 333 capable of receiving the comb member 331, and the collecting hole is opened at the recess 333. Such an embodiment as described above allows the grate members 331 to avoid protruding from the sides of the bus bar 330 after the grate members 331 are installed in the bus bar 330, thereby ensuring that the sides of the bus bar 330 are flat. Meanwhile, when the accumulated water flows to the merging portion 330, the concave portion 333 of the merging portion 330 also has a converging effect on the accumulated water, so that the accumulated water can enter the merging portion 330 more conveniently.

As shown in fig. 1, in one embodiment, the bridge drainage device further comprises a flattened portion 210. The flat part 210 is installed on the bridge deck body 200, the flat part 210 is attached to the first side of the confluence part 330, and the end of the flat part 210 is located at the height position of the first side of the confluence part 330, and the confluence hole is located in the height range of the first side of the confluence part 330. Specifically, the flat part 210 is granite flat stone or concrete stone. Sometimes, due to installation needs or installation errors, the junction hole (the portion of the junction hole closest to the deck body 200) formed in the junction part 330 is higher than the deck body 200. Therefore, the bridge deck body 200 is additionally provided with the flat part 210 for height compensation until the height compensated by the flat part 210 is within the height range of the confluence part 330 of the confluence hole. Such an embodiment can ensure that accumulated water flowing to the confluence part 330 on the bridge deck body 200 can directly enter the confluence part 330, and the accumulated water is prevented from being retained at the connection part of the confluence part 330 and the bridge deck body 200.

In one embodiment, a water stop is provided at the end of the expansion joint mechanism, and the communication between the drainage assembly 400 and the confluence mechanism 300 is separated from the water stop. Specifically, the sealing rod can avoid outside ponding from the tip infiltration expansion joint mechanism or the internal portion of pontic of expansion joint mechanism, has improved the durability of pontic.

As shown in fig. 1, in one embodiment, the drainage assembly 400 includes a drainage straight pipe 410 and a drainage bent pipe 420, a drainage hole is formed on a second side of the merging portion 330, the drainage straight pipe 410 is located between the secondary deck 320 and the supporting base 100, one end of the drainage straight pipe 410 is communicated with the drainage hole, the other end of the drainage straight pipe 410 is communicated with one end of the drainage bent pipe 420, and the other end of the drainage bent pipe 420 penetrates through the supporting base 100. Specifically, because the mounting gap is reserved between the auxiliary road bridge deck 320 and the support base 100 under the action of the supporting cushion block 310, at this time, the drainage straight pipe 410 is paved in the mounting gap, and the drainage straight pipe 410 is in contact with the support base 100, that is, the support base 100 supports the drainage straight pipe 410, and simultaneously, the shake generated when the drainage straight pipe 410 is used for water delivery is also reduced. Then, a mounting hole for the drain trap 420 to pass through is formed in the support base 100, and finally, after the drain trap 420 is connected to the drain branch pipe, the other end of the drain trap 420 passes through the support base 100 via the mounting hole. Such an embodiment as described above avoids that the accumulated water penetrates into the interior of the bridge body when the accumulated water is drained.

As shown in fig. 1, in one embodiment, an adapter tube 411 is disposed at a first end of the straight drainage tube 410, and the straight drainage tube 410 is communicated with the drainage hole through the adapter tube 411. Specifically, the pipe diameter of the adapter pipe 411 is larger than that of the straight drainage pipe 410, and considering that the water flow is large when the accumulated water is guided into the drainage assembly 400 from the confluence mechanism 300, the impact of the accumulated water on the drainage assembly 400 can be effectively transferred by increasing the pipe diameter of the adapter pipe 411, so that the drainage assembly 400 is prevented from being deformed or damaged.

As shown in fig. 1, in one embodiment, the bridge drainage arrangement further comprises an access panel 321. Be equipped with the access hole on the auxiliary road bridge floor 320, the access hole with drainage straight tube 410 reaches drainage return bend 420 is corresponding, access cover 321 movably installs access hole department. Specifically, the drainage straight pipe 410 and the drainage bent pipe 420 are installed at the side of the bridge deck body 200, so that the space of the bridge deck body 200 may not be occupied when the drainage straight pipe 410 or the drainage bent pipe 420 is repaired, that is, the normal running of the vehicle is ensured.
