Description

Technical Field

[0001] The utility model relates to the technical field of bridge parts, in particular to a drainage structure for an elevated bridge. Background Art

[0002] With the rapid increase of urban population, the number of vehicles is also increasing. In order to ensure the smooth flow of traffic and avoid the blockage and congestion of the main routes, the overpass and the elevated road form a multi-layer three-dimensional layout. The emergence of urban viaducts greatly improves the speed and passing capacity, and urban viaducts have become an important symbol of modern cities. In order to ensure that the viaduct can be used normally on rainy days, drainage channels are set on both sides of the bridge deck, and the bottom of the drainage channel is generally directly connected with a drainage pipe by bolts to discharge rainwater. However, this design has great disadvantages. When the drainage pipe is damaged and needs to be replaced, workers need to spend more time to turn the bolts to remove the broken drainage pipe. When installing, it also takes more time to turn the bolts to install the new drainage pipe, so that the drainage pipe cannot be quickly disassembled and installed, which increases the working time of the workers and reduces the work efficiency of the workers. At the same time, when the rainfall is heavy, the rushing water will violently impact the drainage pipe, exerting a lot of pressure on the drainage pipe, which is easy to cause the drainage pipe to rupture. Therefore, it is necessary to provide a drainage structure for viaducts to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to solve the problem that the drainage pipe cannot be quickly disassembled and installed in the prior art, and thus a drainage structure for an elevated bridge is proposed.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a drainage structure for an elevated bridge, including a bridge deck, a drainage channel is opened inside the bridge deck, and the drainage channel has a certain slope, a drainage pipe is arranged at the bottom of the drainage channel, a water pipe groove is opened inside the bottom of the bridge deck, and the water pipe groove is arranged around the bottom of the drainage channel, and the top of the drainage pipe is movably arranged in the water pipe groove.

[0005] Furthermore, blocks are fixedly provided on both sides of the top of the drainage pipe, and two through grooves are opened inside the bottom of the bridge deck. The two through grooves are connected to the water pipe grooves, and the two through grooves are located at the longitudinal ends of the water pipe grooves, and the two blocks are respectively adapted to the two through grooves.

[0006] Furthermore, a circular groove is provided inside the bridge deck, which is connected with the water pipe groove and two through grooves, and the circular groove is located on the top of the water pipe groove and the two through grooves. Card slots are provided at the bottom of both lateral ends of the circular groove, and card rods are fixed inside the two card slots. Card holes are provided in the centers of the two card blocks, and the two card blocks are respectively located in the two card slots, and the two card rods are respectively inserted into the two card holes.

[0007] Furthermore, the inner side wall of the drain pipe is circular and has four fixed blocks fixed at equal intervals. Sliding rods are fixed on the top of the four fixed blocks. Slide blocks are slidably arranged on the surfaces of the four sliding rods. Waterproof springs are fixed between the four slide blocks and the four fixed blocks, and the four waterproof springs are respectively sleeved on the surfaces of the four sliding rods.

[0008] Furthermore, a diverter is movably arranged inside the drain pipe, four sliders are fixedly arranged at four ends of the diverter, and the diverter is located below the drain channel.

[0009] The beneficial effects of the utility model are:

[0010] 1. By arranging water pipe grooves, clamping blocks, through grooves, annular grooves, clamping grooves, clamping rods and clamping holes, when the drain pipe needs to be disassembled, the drain pipe is pushed upward to move, so that the two clamping blocks move upward and leave the two clamping grooves, so that the two clamping blocks move into the annular groove, and then the drain pipe is rotated to make the two clamping blocks correspond to the two through grooves, and then the drain pipe is moved downward to facilitate its quick disassembly, so that the drain pipe can be quickly disassembled and installed, thereby reducing the working time of workers and improving the working efficiency of workers.

[0011] 2. By setting fixed blocks, sliding rods, sliders, waterproof springs and diverters, when the rainfall is heavy, the rushing water flow will violently impact the diverter downward, causing the diverter to move downward, driving the four sliders to move downward on the four sliding rods. The four sliders compress the four waterproof springs downward on the four sliding rods, thereby facilitating the buffering of the diverter, and then facilitating the buffering of the rushing water flow, and then dispersing the rushing water flow through the diverter, which greatly weakens the impact force of the water flow, weakens the damage of the water flow to the pipeline, increases the service life of the pipeline, reduces economic losses, allows the pipeline to continuously and stably perform its drainage function, and ensures the normal traffic on the elevated bridge road surface.
