Rainwater drainage pipe additionally provided with filter screen

Abstract

The invention discloses a rainwater drainage pipe additionally provided with a filter screen. The filter screen is arranged at the connection portion of an upper pipe half and a lower pipe half, a transverse semipermeable drainage pipe is arranged on the inner wall of a drill hole of the upper pipe half, a water stop material is arranged between the lower half portion of the transverse semipermeable drainage pipe and the lower half portion of the drill hole, multiple independent branch pipes are arranged inside the lower pipe half, each branch pipe is arranged between corresponding adjacent tree-shaped rainwater pipe drainage sub-systems, the multiple branch pipes are connected together for forming a netlike rainwater pipe drainage net, each filter screen is arranged to be of a three-layer structure, an upper filter screen body and a lower filter screen body are each a large-hole steel mesh, and an intermediate filter screen body is provided with an activated carbon adsorption film. By means of a netlike rainwater pipe drainage system, the void volume of pipes on other lines can be utilized sufficiently, high water level pressure can be effectively lowered, the phenomena of ponding can be effectively reduced, and drainage safety and smoothness are improved; the filter screen is good in filtering and adsorbing effect, easy to produce and low in cost, and it is helpful to improve the drainage effect.

Description

technical field [0001] The invention belongs to the technical field of drainage pipeline equipment, and in particular relates to a rainwater drainage pipeline with a filter net. Background technique [0002] Drainage pipeline refers to the system composed of pipes and channels and their ancillary facilities for collecting and discharging sewage, waste water and rainwater. Including main pipes, branch pipes and pipelines leading to treatment plants, no matter they are built on streets or anywhere else, as long as they are used for drainage, they should be counted as drainage pipelines. The length of drainage pipes is calculated based on the sum of the lengths of all main drainage pipes, main pipes, branch pipes, inspection wells, and inlets and outlets of connecting wells, excluding the connecting pipes, inlet pipes and open channels between rainwater outlets and drainage pipes. The calculation shall be based on a single pipe, that is, if there are two or more side-by-side d...

Problems solved by technology

Due to the tree-like layout of the rainwater pipeline system, it is determined that the pressure flow drainage difficulty and water accumulation are limited to the upstream pipeline, and have no impact on the downstream pipeline of the pipeline, other pipelines in the system and adjacent rainwater pipeline system pipelines. , can not make more use of the void volume generated in other pipelines and adjacent rainwater piping systems in this system

The traditional drainage pipe is not only a drainage measure, but also a leaky pipeline; there is a gap between the drainage pipe and the drainage area, and some pore water will flow along the gap, and the drainage effect is not ideal. Therefore, it is required to introduce a better drainage effect and simple technology. , a new type of drainage pipe with a wide range of applications
