Description

Technical Field

[0001] This utility model relates to the technical field of drainage auxiliary devices for elevated bridges, and in particular to a drainage auxiliary structure for elevated bridges. Background Technology

[0002] To alleviate urban traffic congestion, many cities are constructing elevated expressways, or viaducts. During the rainy season, water easily accumulates on the surface of these viaducts, affecting their lifespan. Therefore, drainage systems are installed on these viaducts. Existing drainage systems are generally integrated cylindrical units installed in pre-drilled holes in the precast bridge components. These holes are pre-drilled during the production of the precast components, and then the integrated drainage device, i.e., the drainage pipe, is inserted into these holes at the bridge installation site to form the drainage system.

[0003] Existing drainage systems lack filtration capabilities, leading to pipe blockages caused by impurities in rainwater over extended periods. Therefore, designing an auxiliary drainage structure for elevated bridges to address these technical issues is of paramount importance. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing drainage device structures lack filtration functions, and impurities in rainwater will clog the pipes after long-term use, so a drainage auxiliary structure for elevated bridges is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary structure for drainage of an elevated bridge, including a bridge deck drainage outlet, positioning plates symmetrically distributed on the inner wall of the bridge deck drainage outlet, a frame overlapping the positioning plates, a stainless steel filter screen installed in the frame, a guide plate installed below the positioning plates, a treatment box installed below the bridge deck drainage outlet, and discharge pipes evenly distributed at the bottom of the treatment box.

[0006] Preferably, a rectangular plate is installed on the inner wall of the processing box, and a screen is installed in the rectangular plate, the aperture of the screen being smaller than that of the stainless steel filter screen.

[0007] Preferably, the screen is also made of corrosion-resistant material, and an auxiliary ring is installed on the screen. The screen is installed from the opening of the bridge deck drainage outlet.

[0008] Preferably, the frame is equipped with handles.

[0009] Preferably, sliders are installed on both sides of the frame, and a groove is provided on the inner wall of the bridge deck drainage outlet. The sliders are slidably disposed in the grooves, and the cross-section of the sliders is a wedge-shaped structure.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by installing a stainless steel filter screen and sieve structure at the bridge deck drainage outlet, rainwater is filtered in a timely manner, reducing the risk of drainage pipe blockage. Compared with conventional bridge deck drainage outlets without screening devices, the technical solution adopted by this utility model can screen impurities and mud in rainwater, reducing the risk of pipe blockage. The overall structure is compact and easy for workers to install and maintain. The overall structure is directly installed on the bridge deck 1, optimizing the existing working space and solving the problem that existing drainage device structures lack filtration functions, and impurities in rainwater will block the pipes after long-term use.

[0012] 2. In this utility model, during use, sliders are installed on both sides of the frame, and a groove is provided on the inner wall of the bridge deck drainage outlet. The sliders are slidably disposed in the groove. The cross-section of the slider is a wedge-shaped structure, and the frame slides in the groove to play a guiding role. Attached Figure Description

Detailed Implementation

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] This utility model provides an auxiliary drainage structure for an elevated bridge, including a bridge deck drainage outlet 1. Positioning plates 2 are symmetrically distributed on the inner wall of the bridge deck drainage outlet 1. A frame 3 is attached to the positioning plates 2, and a stainless steel filter screen 301 is installed in the frame 3. A guide plate 302 is installed below the positioning plates 2. A treatment box 4 is installed below the bridge deck drainage outlet 1, and discharge pipes 5 are evenly distributed at the bottom of the treatment box 4. A rectangular plate 401 is installed on the inner wall of the treatment box 4, and a screen 402 is installed in the rectangular plate 401. The aperture of the screen 402 is smaller than that of the stainless steel filter screen 301. The screen 402 is also made of corrosion-resistant material. An auxiliary ring 403 is installed on the screen 402. The screen 402 is installed from the opening of the bridge deck drainage outlet 1, providing space for future disassembly and maintenance.

[0018] In actual use, the auxiliary drainage structure for the viaduct includes a rectangular plate 401 in the treatment box 4, a screen 402 on the rectangular plate 401, and a stainless steel filter 301 at the bridge deck drainage outlet 1. The stainless steel filter 301 forms the first layer of filtration at the bridge deck drainage outlet 1, performing preliminary filtration and screening to remove dust clumps and large particles formed after rainwater runoff, reducing the risk of clogging. The screen 402 then forms the second layer of filtration, further filtering the pre-filtered rainwater. Both the stainless steel filter screen 301 and the screen 402 structure are detachable and can be installed in the bridge deck drainage outlet 1, which is conducive to later disassembly and maintenance. By installing the stainless steel filter screen 301 and the screen 402 structure at the bridge deck drainage outlet 1, rainwater can be filtered in time, reducing the risk of drainage pipe blockage. Compared with the conventional bridge deck drainage outlet 1 without a screening device, the technical solution adopted by this utility model can screen impurities and mud in the rainwater, reducing the risk of pipe blockage. The overall structure is compact and easy for workers to install and maintain. The overall structure is directly installed on the bridge deck 1, optimizing the existing working space.

[0019] Example 1

[0020] like Figure 1-2 As shown, a handle 305 is installed on the frame 3, and sliders 303 are installed on both sides of the frame 3. A groove 304 is provided on the inner wall of the bridge deck drainage outlet 1, and the slider 303 is slidably disposed in the groove 304. The cross-section of the slider 303 is a wedge-shaped structure.

[0021] The effect achieved by the entire embodiment 1 is that, in use, sliders 303 are installed on both sides of the frame 3, and a groove 304 is provided on the inner wall of the bridge deck drainage outlet 1. The sliders 303 are slidably disposed in the groove 304. The cross-section of the sliders 303 is a wedge-shaped structure. The frame 3 slides in the groove 304 to play a guiding role.

[0022] Working principle: A rectangular plate structure is set in the treatment box, and then a screen structure is installed on the rectangular plate. Then, a stainless steel filter screen structure is installed at the bridge deck drainage outlet. The stainless steel filter screen forms the first layer of filtration and protection structure at the bridge deck drainage outlet, performing preliminary filtration and screening to remove dust clumps and large particles formed after rainwater runoff, reducing the risk of clogging. Then, the screen structure forms the second layer of filtration to further filter the rainwater after the preliminary filtration. Both the stainless steel filter screen and the screen structure can be disassembled and installed in the bridge deck drainage outlet, which is convenient for later disassembly and maintenance.
