Building drainage structure capable of reducing blockage

Abstract

The invention relates to a building drainage structure capable of reducing blockage, and relates to the technical field of drainage devices.The building drainage structure comprises a sub-drainage pipe arranged in a foundation, the sub-drainage pipe is connected with a main drainage pipe, a filter plate is arranged in the sub-drainage pipe, a plurality of filter holes are formed in the filter plate, a supporting rod is fixedly arranged in the sub-drainage pipe, and the supporting rod is connected with the main drainage pipe. A cleaning rod is arranged on the supporting rod; a guide rod is arranged on the supporting rod, the guide rod penetrates through the filter plate, the guide rod is sleeved with an abutting spring, the side wall of the sub drainage pipe is connected with an auxiliary drainage pipe, the auxiliary drainage pipe is located below the filter plate, and the auxiliary drainage pipe is communicated with the main drainage pipe; a blocking piece is arranged in the auxiliary drainage pipe and used for blocking impurities in the auxiliary drainage pipe. The device has the effects that the phenomenon of drainage blockage is reduced, and accumulated impurities are automatically recycled.

Description

technical field [0001] The present invention relates to the technical field of drainage devices, in particular to a building drainage structure that reduces clogging. Background technique [0002] At present, the building drainage structure usually refers to the rainwater and sewage pipes under the municipal roads, which are commonly known as "sewage pipes". The building drainage structure needs to have a certain filtering function to prevent debris from entering the drainage pipe and causing the drainage pipe to be blocked, thereby affecting the drainage function of the drainage structure. [0003] The Chinese patent with the authorization announcement number CN210713148U designed in the related art provides a municipal building drainage structure, which includes a support frame and a manhole cover arranged on the support frame, and the manhole cover is provided with a plurality of drainage outlets; It can block the larger impurities in the sewage, and the sewage enters th...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing this application, the inventor found that there are at least the following problems in this technology: the drainage outlet on the manhole cover is small, and when the sewage contains relatively large impurities, impurities such as leaves and garbage are easy to block the drainage outlet, resulting in drainage blockage , so it needs to be improved
