Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, and particularly relates to a drainage ditch structure with an impurity filtering structure for municipal engineering. Background Technique

[0002] Urban sewage discharge has become the main source of urban water pollution in our country. Urban sewage treatment is a key point in current and future urban water conservation and urban water environment protection work. In order to facilitate the discharge of this sewage, a large number of drainage structures are often designed and built in cities. However, in some special areas, heavy rainfall often occurs, and ordinary drainage structures are easily blocked and difficult to cope with heavy rainfall, resulting in floods in cities.

[0003] For example, the Chinese utility model provides "a multi-layer filtering drainage ditch", and its publication number is: CN211816821U, which includes at least two layers of filter plates. The first-layer filter plate includes a first angle steel embedded in the socket joints on both sides of the drainage ditch, first horizontal support rods evenly spaced between the angle steels, and a filter steel plate laid on the first horizontal support rods. The top surface of the filter steel plate is flush with the horizontal flange plate of the angle steel; the second-layer filter plate includes a second angle steel, a support frame arranged between the two second angle steels, and a fiber filter net wrapped on the support frame. The horizontal flange plate of the second angle steel overlaps on a horizontal support plate arranged on the vertical flange plate of the first angle steel. The support frame plate is inserted into a slideway arranged on the vertical flange plate of the second angle steel. The whole filter plate adopts a detachable splicing method, which is convenient for cleaning and installation. The multi-layer filtering method can filter out impurities as small as rice grains, thus avoiding the blockage of the drainage ditch by sundries and the generation of unpleasant odors and flying insects due to the deterioration of sundries.

[0004] In the process of realizing the present utility model, the inventor found that at least the following problems exist in this technology. The drainage ditch structure in the above patent does not have the function of cleaning the fallen leaf impurities filtered out during use, and thus is prone to blockage, and cannot improve the drainage efficiency of the drainage ditch. For this reason, we propose a drainage ditch structure with an impurity filtering structure for municipal engineering. Content of the Utility Model
