Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1, a drainage treatment structure for a drainage ditch of a bridge road, comprising a sand settling ditch 1 and a drainage ditch 2, wherein the sand settling ditch 1 and the drainage ditch 2 are both square structures, the middle part of the bottom end of the drainage ditch 2 is communicated with a vertical pipe 3, an interlayer 4 is arranged between the sand settling ditch 1 and the drainage ditch 2, one side of the interlayer 4, which is positioned at the drainage ditch 2, is provided with a chute 5, the chute 5 is connected with a sliding plate 6 in a sliding way in the vertical direction, one side of the sliding plate 6 is provided with an overflow port I7 and a drainage port I8 in sequence from top to bottom, the inner side of the chute 5 is provided with an overflow port II 10 and a drainage port II 11 in sequence from top to bottom, the sliding plate 6 is positioned at one side of the drainage ditch 2, the upper end of the drainage port I8 is fixedly connected with a floating plate 9, a double-layer step 12 is arranged at the port part of the sand settling, and the top cover 15 is of a pore plate structure, and the lower end of the square frame 13 is fixedly connected with a filter mesh bag 14.

The sliding groove 5 and the sliding plate 6 are both in a T shape, the sliding plate 6 is limited to slide in the sliding groove 5, and the sliding groove 5 and the sliding plate 6 can also adopt other structures with limiting effects.

The shapes and sizes of the overflow port I7, the overflow port II 10, the water outlet I8 and the water outlet II 11 are the same, and the sliding plate 6 is provided with parts capable of blocking the overflow port I7 and the water outlet I8 at the upper end and the lower end thereof.

The longitudinal length of the filter mesh bag 14 is larger than that of the desilting ditch 1, so that the filter mesh bag 14 is partially stacked in the desilting ditch 1 to avoid the dragging of impurities.

The height of the inner bottom surface of the desilting ditch 1 is higher than that of the inner bottom surface of the drainage ditch 2, so that rainwater cannot accumulate in the desilting ditch 1, and the condition that microorganisms grow to cause odor is avoided.

In rainy days, the bottom end of the sliding plate 6 is abutted against the inner bottom surface of the sliding groove 5 under the action of the gravity of the sliding plate, the first overflow port 7 is positioned at the upper end of the second overflow port 10, and the first water outlet 8 is opposite to the second water outlet 11;

in rainy days and when the rainfall is small, rainwater flows into the desilting ditch 1 through the top cover 15, impurities are intercepted in the filter mesh bag 14, and the rainwater without impurities is discharged into the drainage ditch 2 through the second drainage port 11 and the first drainage port 8 and is discharged through the vertical pipe 3;

in rainy days, when the rainfall is large and the drainage quantity of the vertical pipe 3 is far smaller than the water inflow quantity of the drainage ditch 2, in the process that rainwater gradually enters the drainage ditch 2, the rainwater liquid level in the drainage ditch 2 gradually rises to the lower end of the floating plate 9, the floating plate 9 gradually drives the sliding plate 6 to rise so that the drainage port I8 and the drainage port II 11 are staggered, the overflow port I7 is opposite to the overflow port II 10, in the process, the situation that the vertical pipe 3 discharges the water in the drainage ditch 2 and the sliding plate 6 gradually moves downwards is likely to occur, the consideration is not taken into consideration, then the water in the desilting ditch 1 flows into the drainage ditch 2 through the overflow port II 10 and the overflow port I7, the purpose of the arrangement is to form a water storage buffer space between the desilting ditch 1 and the drainage ditch 2 and avoid frequent scouring of impurities at the bottom in the filtering mesh bag 14 to cause the blockage of the impurities and influence on the filtering situation, and the bottom of the filtering is formed to deposit, when the amount of rainwater is gradually reduced, the sliding plate 6 is lowered to the bottom end position of the sliding chute 5 again, and the state of draining water through the second water outlet 11 and the first water outlet 8 is restored.

After long-time use, when filter bag 14 interception impurity is more, can take out top cap 15, square frame 13 that stack on double-deck step 12 in proper order, pour the processing in the impurity that filter bag 14 was collected concentratedly, maintain convenient simple and efficient.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
