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, an integrated anti-blocking bridge floor rainwater drainage port comprises a box body 18 pre-buried at a low point on one side of a bridge floor and adjacent to a bridge sidewalk or an anti-collision body 13, a vertical partition plate 7 extending along a crossing line of the bridge floor and the adjacent bridge sidewalk or the anti-collision body 13 is arranged in the box body 18, the middle upper part of the box body 18 is divided into two parts by the vertical partition plate 7, one part is a precipitable chamber 5 positioned below the bridge floor, the other part is an overflow chamber 6 positioned below the bridge sidewalk or the anti-collision body 13, the overflow chamber 6 is provided with a lateral vertical rainwater gate positioned at the bottom of the edge of the bridge sidewalk or the edge of the anti-collision body, a vertical rainwater grate 1 is installed on the lateral vertical rainwater gate, the precipitable chamber 5 is provided with a planar rainwater gate positioned on the bridge floor and adjacent to the lateral vertical rainwater gate, a planar rainwater grate 2, but sediment chamber 5's bottom is equipped with a supporting beam 11 upper berth is equipped with check guest's box-type 9 intussuseption is filled with rubble or water permeability material 10 the bottom of box 18 is connected with rainwater standpipe 12, rainwater standpipe 12 is located can sediment chamber 5's below, the lower part of box 18 through domatic with rainwater standpipe 12 is connected, overflow rainwater can discharge smoothly when being convenient for can sediment chamber 5 blocks up.

In this embodiment, the grippe net box 9 is provided with a handle 8 for easy cleaning. The lateral vertical rainwater inlet is provided with a limiting groove 3, and the vertical rainwater grate 1 is installed in the limiting groove 3 of the lateral vertical rainwater inlet. The plane rainwater grate 2 is arranged in the limiting groove 4 of the plane rainwater port. 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. The check guest net cage 9 is a stainless steel check guest net cage, so that the corrosion can be avoided, and the service life is prolonged.

By adopting the water outlet, in sunny days, the vertical rainwater grate 1 and the plane rainwater grate 2 can effectively intercept garbage and sundries with large particle sizes from the bridge floor, and the sundries or dust with small particle sizes are intercepted by the check net box 9 in the settling chamber 5 after penetrating through the rainwater grate and are prevented from falling into the rainwater vertical pipe 12. When the drainage port is maintained and cleaned, the plane rainwater grate 2 is only required to be moved away, and the check net box 9 is pulled out of the box body 18, so that cleaning can be completed, and the device is simple and convenient.
