Municipal road drainage system

Abstract

The invention discloses a municipal road drainage system. The municipal road drainage system comprises a drainage assembly, wherein a first step groove and a drainage well are sequentially formed in the upper surface of a road main body from top to bottom, a drainage cover is arranged in the first step groove, and a plurality of flow holes are formed in the drainage cover; a plugging mechanism is arranged in the drainage well, the plugging mechanism comprises a plugging assembly and a control assembly, the plugging assembly comprises a fixing rod, a fixing plate, a first spring, a sealing plate and an inserting block, the fixing rod penetrates through the sealing plate and is connected with the sealing plate in a sliding mode, and the top of the sealing plate abuts against the bottom of the drainage cover; and the control assembly is used for driving the top of the sealing plate to be separated from the bottom of the drainage cover during rainfall. According to the scheme, when rainfall does not occur, under the elastic force action of the first spring, the top of the sealing plate abuts against the bottom of the drainage cover, the inserting block is matched with the flow holes in an inserting mode, so that the probability that impurities such as dust enter the flow holes and block the flow holes is reduced; and when rainfall occurs, the control assembly controls the sealing plate to be far away from the drainage cover, so that the inserting block is separated from the flow holes, and the drainage work is facilitated.

Description

technical field [0001] The invention relates to the technical field of municipal drainage, in particular to a municipal road drainage system. Background technique [0002] Drainage system refers to the overall combination of drainage collection, transportation, water quality treatment and discharge facilities in a certain way, and is used to eliminate waterlogging, prevent waterlogging and prevent salt. Drainage adjustment network, all levels of drainage ditches, waterlogging lakes, drainage sluices, pumping and drainage pumping stations, and drainage capacity and discharge areas. The excess water in the drainage area first flows into the field drainage regulation network, and then is discharged to the drainage area by the drainage sluice or the pumping station through the drainage ditches at all levels or after being stored in the lake. [0003] A municipal road drainage structure is disclosed in the Chinese utility model patent with the notification number CN211774444U, w...

Problems solved by technology

[0004] However, the inventor believes that the above-mentioned technical solution has the following defects: in order to ensure the drainage efficiency, there are multiple flow holes on each drainage cover. The probability is that when it is not raining, dust and other sundries accumulate on the filter screen and block the flow holes on the drain cover, which affects the drainage efficiency of the drain cover when it rains
