Detailed Description

For further understanding of the contents, features and effects of the present invention, the following embodiments are exemplified and will be described in detail with reference to the accompanying drawings:

referring to fig. 1 to 3, the integrated anti-blocking easy-to-clean bridge deck rainwater drainage port comprises a box body 1 pre-embedded at a low point of a bridge roadway, a horizontal grid plate 11 is arranged at the lower part of the box body 1, a grid filter barrel 4 with a conical top cover is placed on the horizontal grid plate 11, and broken stones or water permeable materials 9 are filled in the grid filter barrel 4 to intercept impurities such as small-particle-size dust. The middle upper part of the box body 1 is divided into a discharge chamber 5 positioned on the upper part and an annular overflow chamber 6 positioned on the lower part by the grid filter barrel 4, the top of the box body 1 is provided with a rainwater grate 2, the bottom of the box body 1 is connected with a rainwater vertical pipe 12, and the lower part of the box body 1 is connected with the rainwater vertical pipe 12 through a slope surface, so that rainwater can be smoothly discharged.

In this embodiment, the main body of the grid filter barrel 4 is of a cylindrical structure, and the tapered top cover of the grid filter barrel 4 is of a conical structure. Horizontal grid plate 11 is supported by spacing strip 10 that is located its below, spacing strip 10 is fixed in box 1, be convenient for pull out horizontal grid plate 11, simple structure. The grid filter barrel 4 is made of stainless steel grid plates, so that the corrosion can be avoided, and the service life is prolonged. Similarly, the horizontal grid plate 11 is made of a stainless steel grid plate. The horizontal grid plate 11 is fixedly connected with a limiting block 7 of the grid filter barrel 4 and used for fixing the position of the grid filter barrel 4. The top of the box body 1 is provided with a limiting groove 3, and the rainwater grate 2 is arranged in the limiting groove 3. The rainwater grate is fixed by the limiting groove, so that the rainwater grate is prevented from falling off and shaking and is convenient to install and maintain.

By adopting the water outlet, in sunny days, the rainwater grate 2 can effectively intercept garbage and impurities with large particle sizes from the bridge floor, the impurities or dust with small particle sizes are intercepted by the grating filter barrel 4 and the horizontal grating plate 11 in the box body 1 after penetrating through the rainwater grate 2, the conical top cover of the filter barrel 4 is convenient for separating the garbage with small particle sizes to the peripheral annular overflow chamber and is intercepted by the horizontal grating plate 11, and the impurities or dust with small particle sizes can be prevented from falling into the rainwater vertical pipe 12. When the drainage port is maintained and cleaned, the rainwater grate 2 is only required to be moved away, and the horizontal grid plate 11 and the grid filter barrel 4 are pulled out of the box body 1, so that cleaning can be completed, and the device is simple and convenient. If meet proruption heavy rain, and rubbish in the box 1 fails in time to clear up, then the water level in the annular overflow cavity 6 will sharply rise to discharge to rainwater standpipe 12 through the side grid 8 of grid filter vat 4 and rubble or the water permeability material 9 in the grid filter vat 4, can guarantee that the whole discharge capacity in outlet is not influenced, can effectively avoid bridge floor ponding.

The main body of the water outlet adopts a box-shaped structure, the box body 1 is pre-embedded to a set position by adopting backfill concrete 15 in the construction process, the bridge sidewalk or the anti-collision body 13, the bridge guardrail 14, the bridge deck asphalt structure layer 16, the concrete cushion layer 17 and the bridge box body 18 are constructed according to the conventional process, special measures are not needed, and the construction difficulty is not increased.

In the construction process, the box body 18 is pre-buried to the lower point of the bridge deck, the bridge guardrail 14, the bridge deck asphalt structure layer 16, the concrete cushion 17 and the bridge box body 19 are constructed according to the conventional process, special measures are not needed, and the construction difficulty is not increased.

Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention, which is within the scope of the present invention.
