Description

Technical Field

[0001] The utility model belongs to the technical field of drainage devices, in particular to a drainage device for an elevated bridge on an expressway. Background Art

[0002] During the construction of elevated bridges on urban expressways, cap beams, piers and box beams are currently mostly constructed in prefabricated and assembled styles. After the erection and installation of prefabricated piers, cap beams and box beams, auxiliary structures such as anti-collision guardrails and bridge deck pavement need to be constructed. The bridge deck pavement mostly uses 8cm thick C50 reinforced concrete (anti-seepage grade S6) leveling layer + 2mm waterproof layer + 10cm noise reduction asphalt concrete, and the anti-collision guardrail is generally constructed with cast-in-place concrete structure. The length of each bridge deck is about 120m, and 80-type noise reduction comb plate expansion joints will be set. There are rainwater inlets and drainage pipes on both sides of the bridge deck. Local rainwater or accumulated water will enter the end of the bridge deck expansion joint through the weak link at the boundary between the bridge deck surface layer and the anti-collision guardrail and eventually seep into the cap beams on both sides of the bridge. Water that seeps onto the cap beams on both sides of the bridge will leave water stains on the cap beams, affecting the overall appearance of the bridge. If there is a road under the bridge, the water stains on the cap beams will drip onto the windshields of cars driving on the road, which will also have a certain impact on the driving of the cars. The water stains on the cap beams will drip onto pedestrians, wetting their clothes and causing a certain impact on them.

[0027] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0028] like Figure 1 to Figure 3 As shown, a drainage device for an expressway viaduct in one embodiment of the utility model includes a plurality of bridge bodies S1, a cap beam S2 is installed at the lower end of the bridge body S1, the cap beam S2 is installed at the joint of two adjacent bridge bodies S1, and an expansion joint S3 is installed at the joint of the two bridge bodies S1. The expansion joint S3 can effectively reduce noise and improve the comfort of road use. Among them, an original drainage pipe 10 is installed on the bridge body S1, and the original drainage pipe 10 is used to drain the accumulated water on the bridge body S1.

[0029] like Figure 1 to Figure 3 As shown, the drainage device includes a water collection structure and a liquid infusion structure, which are interconnected. The water collection structure is used to collect the flowing water at the end of the expansion joint S3, and the end of the liquid infusion structure away from the water collection structure is connected to the original drainage pipe 10. That is, the water collected by the water collection structure can be transported to the original drainage pipe 10 through the liquid infusion structure, and the water is discharged from the original drainage pipe 10.

[0030] Specifically, Figure 1 to Figure 3 As shown, the water collection structure includes a first water collection pipe 1, which is a semicircular water collection structure, installed at the lower end of the bridge body S1, and matches the position of the expansion joint S3, so as to collect water flowing out through the expansion joint S3. The lower end of the first water collection pipe 1 is fixedly connected with an expansion joint 3, which can expand the volume of the first water collection pipe 1. When the water flow rate of the expansion joint S3 is too fast, the first water collection pipe 1 and the expansion joint 3 are combined to temporarily store the water flowing out of the expansion joint S3, and then transported to the original drain pipe 10 by the infusion structure and discharged.

[0031] like Figure 1 to Figure 3 As shown, the infusion structure includes a first connecting pipe 5, one end of which is connected to the expansion joint 3, and the other end is equipped with a connector 6, and the end of the connector 6 away from the first connecting pipe 5 is equipped with a second connecting pipe 7, and the other end of the second connecting pipe 7 is connected to the original drainage pipe 10. Generally, the first connecting pipe 5 is vertically arranged, and the second connecting pipe 7 is horizontally arranged.

With such an arrangement, the infusion structure is more beautiful, and the beauty of the expressway viaduct is improved to a certain extent.

[0032] In the above embodiment, the leakage water is collected by the water collection structure and the liquid infusion structure, and the leakage water is drained into the original drainage pipe 10, so as to reduce the leakage water leaving water stains on the bridge body S1 or the cap beam S2, which affects the appearance of the expressway viaduct. At the same time, it can also reduce the leakage water dripping on the road vehicles or pedestrians under the expressway viaduct as much as possible, reducing the impact of the leakage water on the vehicles or pedestrians.

[0033] In another embodiment, if Figure 1 to Figure 3 As shown, a first sealing gasket 2 is fixedly connected to the contact surface between the first water collecting pipe 1 and the expressway viaduct. The first sealing gasket 2 is generally made of rubber. A third groove 11 is respectively provided at both ends of the first water collecting pipe 1. A clamp 4 matching the third groove 11 can be installed on the first water collecting pipe 1, and the first water collecting pipe 1 is fixedly connected to the bridge body S1 through the clamp 4. The clamp 4 fixes the first water collecting pipe 1 to the bridge body S1 by bolts. During the fixing process, the clamp 4 applies pressure to the first water collecting pipe 1, causing the first sealing gasket 2 to deform, thereby increasing the sealing between the first water collecting pipe 1 and the bridge body S1. Reduce water leakage from the connection between the first water collecting pipe 1 and the bridge body S1.

[0034] In another embodiment, the water collection structure includes a second water collection pipe 8, the lower end of which is fixedly connected with an expansion joint 3, the expansion joint 3 is used to increase the volume of the second water collection pipe 8, and the expansion joint 3 is connected to the infusion structure.

Since the second water collection pipe 8 and the third water collection pipe 9 are slidable, that is, the size of the water collection structure can be changed, so that the water collection structure can face bridges of different lengths, thereby improving the applicability of the water collection structure.

[0035] Specifically, Figure 4 As shown, sliders 93 are fixedly connected to both side walls of the third water collecting pipe 9, and a slide groove 83 matching the slide groove 93 is provided on the inner wall of the second water collecting pipe 8. The third water collecting pipe 9 is slidably connected to the second water collecting pipe 8 through the cooperation of the slide groove 83 and the slider 93, and the length of the water collecting structure can be changed during the sliding process.

[0036] like Figures 4 to 6 As shown, first grooves 82 are respectively provided on both sides of the second water collecting pipe 8, and a second groove 92 is provided on the third water collecting pipe 9. Both the first groove 82 and the second groove 92 match the clamp 4. The second water collecting pipe 8 can be fixedly connected to the bridge body S1 through the clamp 4, and the third water collecting pipe 9 can also be fixedly connected to the bridge body S1 through the clamp 4, thereby further fixing the third water collecting pipe 9.

[0037] like Figures 4 to 6As shown, a second sealing gasket 81 is installed on the contact surface between the second water collecting pipe 8 and the expressway viaduct, and a third sealing gasket 91 is installed on the contact surface between the third water collecting pipe 9 and the expressway viaduct. The second sealing gasket 81 and the third sealing gasket 91 are both used to increase the sealing between the second water collecting pipe 8 and the third water collecting pipe 9 and the bridge body S1, and to avoid water leakage from the connection between the third water collecting pipe 9 and the bridge body S1 and the connection between the second water collecting pipe 8 and the bridge body S1 as much as possible.

[0038] In the above embodiment, by setting the second water collecting pipe 8 and the third water collecting pipe 9, the length of the water collecting structure can be changed, making the water collecting structure more adaptable, and the length can be fine-tuned according to the specifications of the bridge body S1, thereby improving the practicality of the variable water collecting structure.
