Abstract

The invention relates to the technical field of municipal drainage, in particular to a reverse dredging device for a drainage pavement, which comprises a hollow pressurizing cylinder, a pressure release valve communicated with an inner cavity of the pressurizing cylinder is arranged on the outer side wall of the pressurizing cylinder, a mounting ring is arranged at the top of the pressurizing cylinder, and a cover plate is arranged at the top of the mounting ring. A pressurizing cavity is defined by the cover plate, the mounting ring and the pressurizing cylinder, a pressurizing assembly used for pressurizing air into the pressurizing cylinder is arranged in the pressurizing cavity, an air inlet hole communicated with the pressurizing cavity is formed in the cover plate, a mounting well is formed in the drainage road surface, the pressurizing cylinder is located in the mounting well, and the cover plate is arranged at the wellhead of the mounting well in a sealed mode. The method has the advantage of environmental protection.

Description

technical field [0001] The invention relates to the technical field of municipal drainage, in particular to a reverse dredging device for drainage pavement. Background technique [0002] In recent years, with the development of road science and technology, drainage pavement has attracted more and more attention from road workers. Drainage pavement refers to a pavement structure with a pavement porosity of 18% to 25%. When it rains, rainwater can pass through the pores of the pavement. Drain quickly. At present, the permeable pavement materials used are mainly permeable concrete, permeable asphalt, permeable brick and so on. [0003] The Chinese patent with the publication number of CN112878131A discloses a drainage pavement structure, which includes a first asphalt layer, and the first asphalt layer includes a drainage asphalt mixture. [0004] In the long-term use of the above-mentioned drainage pavement, its drainage performance may gradually decrease. In the final analy...
