Meshed rainwater pipeline drainage system

Abstract

A reticular rainwater pipes drainage system comprises a plurality of independent dendritic rainwater pipes drainage subsystems (1a-1f) leading to a channel respectively. A plurality of first intercommunicating rainwater pipes manholes (2) are respectively set between adjacent dendritic rainwater pipes drainage subsystems (1a-1f) so as to make adjacent dendritic rainwater pipes drainage subsystems (1a-1f) communicate with each other. All of the dendritic rain water pipes drainage subsystems (1a-1f) are connected together to form the reticular rainwater pipes drainage system, so that each independent dendritic rainwater pipes drainage subsystems (1a-1f) and dendritic rainwater pipes of the subsystems are interconnected. When drainage problem in certain dendritic rainwater pipes drainage subsystems (1a-1f) occurs by reason of heavily local rainfall, the drainage system can utilize the other subsystems and the void volume of rainwater pipes in the system to drain rainwater as quickly as possible, so as to enhance an ability to drain rainwater. The reticular rainwater pipes drainage system is improved to form on the basis of current dendritic rainwater pipes drainage system without being rebuilt over again and cost is saved.

Description

technical field [0001] The invention relates to an urban drainage system, in particular to a mesh rainwater pipe drainage system for urban drainage. Background technique [0002] In the urban construction area, the rainwater pipeline system is responsible for the main task of urban rainwater drainage. Rainwater pipes are arranged according to the distribution of buildings, road network, topography and river location. The rainwater pipeline system generally consists of a rainwater outlet, a rainwater branch pipe, a rainwater pipe, an inspection well and a rainwater discharge outlet. The rainwater pipelines (including the rainwater branch pipes and the rainwater discharge outlets) are connected by inspection wells and arranged under the urban roads in a tree form, forming multiple adjacent and independent tree-like rainwater pipeline systems. [0003] The characteristic of the tree-like rainwater pipeline system is that the rainwater pipelines of different diameters in the w...

AI Technical Summary

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
