The specific implementation mode is as follows:

the present invention will be further described with reference to fig. 1, fig. 2, fig. 3, fig. 4 and fig. 5:

example 1, as shown in fig. 1, 2, 3 and 4:

in this embodiment, the utility model discloses it includes a supporting steel plate 7 that has the center round hole, supporting steel plate 7 that has the center round hole can directly set up with current bridge on according to the pipeline mouth department of the drainage pipe that the displacement set up, its center round hole coincide with current drainage pipe's pipeline mouth can, as shown in fig. 3. In order to ensure the service life of the supporting steel plate 7, the supporting steel plate is made of stainless steel materials.

In order to realize the utility model discloses filter the purpose of impurity in the rainwater, link up a filter equipment on the supporting steel plate 7 that has central round hole. In actual operation, the filter device is placed in the central circular hole.

In this embodiment, the filtering device is a filtering barrel with a plurality of drainage holes 4 uniformly distributed on one side wall; the top of the filter vat 6 is provided with an extension annular connecting edge 2, and the extension annular connecting edge 2 is provided with a handle 1. The extension annular connecting edge 2 has the advantages that a handle can be welded on the extension annular connecting edge firstly, so that the filtering barrel part can be conveniently and timely lifted out to remove impurities, and the good filtering effect of the filtering barrel is ensured. Another purpose is to support the whole filter vat on the support steel plate 7, completing the placement of the filter vat.

In order to further filter impurities, a horizontal grating plate 3 is arranged at the upper part in the filter barrel, and the horizontal grating plate 3 can primarily filter the impurities.

The water drainage holes 4 are distributed on the side wall 5 from the lower part of the horizontal grid plate 3 to the position which is half of the barrel height away from the barrel bottom, in the embodiment, the aperture of the water drainage holes 4 is 8-10mm, and the hole spacing is 40-50 mm.

Because the horizontal grid plate is provided with certain impurities, a certain support is required, so that the horizontal grid plate is stable in the filter vat and is convenient to move when slag is removed. And a supporting piece for supporting the horizontal grating plate is arranged on the barrel wall below the horizontal grating plate 3. In this embodiment, the support member is a support ring 51 attached to the wall of the tub.

The distance L3 between the horizontal grid plate 3 and the top of the filter barrel is one fourth of the barrel height, the horizontal grid plate is made of stainless steel material, the distance L1 between the lowest row of the water outlet holes and the barrel bottom is one half of the barrel height, so that the filter barrel is actually divided into three parts, the first part is the space between the horizontal grid plate 3 and the top of the filter barrel, the space is a first drainage filtering space, the second part is the space with uniformly distributed water outlet holes, the space is a drainage space, and the third part is the space between the barrel bottom and the lowest row of the water outlet holes, the space is an impurity precipitation space.

The utility model discloses a filter vat 6 can make circular bucket or square bucket according to bridge actual design demand. The filter vat is made of stainless steel materials, so that the service life of the filter vat can be ensured.

Usually the drain is arranged at the road edge 8 and is provided with a rain grid 9, which rain grid 9 is movable.

In the specific construction, as shown in fig. 3 and 4, the rain water grid 9 is removed, the supporting steel plate 7 is arranged under the pavement layer 10 at the position of the water drainage port, and then the filtering barrel 6 is lifted up by the handle 1 and is placed in the central circular hole of the supporting steel plate 7, so that the filtering barrel is ensured to be placed in the drainage pipeline 11. The rain grid 9 is then repositioned. When rainwater enters the filter barrel through the rainwater grid 9, the rainwater is firstly filtered by the horizontal grid plate 3, a part of large impurities are isolated, the rest fine impurities enter an impurity precipitation space of the filter barrel along with the rainwater, the fine impurities are precipitated at the barrel bottom, and the rainwater overflows from the water drainage hole 4 and enters the bridge drainage pipeline. The filter vat can be conveniently lifted out to remove all impurities and put in place. Regular cleaning can always keep the drainage pipeline smooth, and the drainage efficiency is effectively improved.

Example 2, as shown in fig. 5, in this example, the supporting member is a supporting triangle 52 attached to the wall of the tub. The supporting triangles are supporting pieces with uniformly distributed triangular structures. The design can ensure the support of the horizontal grid plate, reduce the resistance of the wall of the filter barrel and is more beneficial to smooth drainage.

In this embodiment, the filtering barrel is an oval barrel, and correspondingly, the horizontal grating plate is also an oval structure.

The rest of this example is exactly the same as example 1.
