Abstract

The invention discloses a blind pipe for municipal greening and a manufacturing method thereof. The blind pipe comprises a pipe body, wherein the pipe body comprises an annular pipe wall and an innercavity surrounded by the pipe wall; and water seepage holes are formed in the pipe body, the water seepage holes communicate with the inner cavity, and the water seepage holes extend continuously in the length direction of the pipe body. According to the blind pipe for the municipal greening and the manufacturing method thereof, the blind pipe with multiple and different water seepage hole types is provided, the blind pipe is simple in structure and simple and convenient to manufacture, and is suitable for different construction conditions and drainage needs in municipal greening engineering.

Description

technical field [0001] The invention relates to the field of municipal greening pipelines, in particular to a blind pipe for municipal greening and a manufacturing method thereof. Background technique [0002] Blind pipe, also known as drainage blind pipe and blind ditch, is a geotechnical product made mainly of synthetic fibers, plastics, and synthetic rubber through different processes. The blind pipe has a very high surface water seepage capacity and internal water flow capacity, and its main function is to collect water seepage in the drained soil to reduce groundwater pressure and remove excess water. Existing blind tubes are mostly three-dimensional porous materials formed by heating and melting thermoplastic synthetic resins, extruding fiber filaments through nozzles, and fusing their joints. The manufacture is cumbersome, costly, and simple in structure. In addition, a large number of blind pipes are needed in municipal greening projects, and their drainage requirem...
