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.

Description

Mesh rainwater drainage system

Technical field

The present invention relates to an urban drainage system, and more particularly to a mesh rainwater drainage system for urban drainage.

Background technique

In urban construction areas, the rainwater pipeline system is responsible for the main tasks of urban rainwater removal. Rainwater pipelines are arranged according to the distribution of the buildings, the road network, the terrain and the location of the river. The rainwater pipeline system generally consists of a gully, a gully branch pipe, a rainwater pipe, an inspection well, and a rainwater discharge port. Each rainwater pipe (including the gully branch pipe and the rainwater discharge port) is connected by the inspection well and arranged under the urban road in the form of a tree to form a plurality of adjacent and independent tree-like rainwater pipe systems.

The tree-shaped rainwater pipeline system is characterized in that the rainwater pipelines of different pipe diameters in the river basin are connected by the inspection wells, and the downward connection is started from the starting rainwater pipes, and the intermediate branch pipelines, the trunk pipelines and the trunk pipelines are connected to the only rainwater drainage pipeline. Export. Rainwater flows in one direction in the rainwater pipe, and is finally discharged to the rainwater discharge port through the multiple rainwater pipelines and intermediate rainwater pipelines in the system. It can also be seen from the current composition of the rainwater inspection well that there are many rainwater drainage pipes (including the stormwater branch pipe) that are discharged into the well, but only one discharge rainwater pipe is discharged downstream, as shown in Figure 1. Show.

Currently, urban stormwater pipelines are designed for full flow. Under normal circumstances, the designed rainwater pipeline can meet the drainage requirements when actual rainfall is planned and designed. However, due to the change of topography and catchment area and uneven rainfall in urban construction areas, it will be difficult for some rainwater pipelines to drain due to excessive amounts of rainwater. In pipelines where drainage difficulties occur, rainwater that cannot be drained in time can only be accumulated in upstream inspection wells and rainwater pipelines (including stormwater branch pipes) to form pressure flow drainage. In severe cases, the accumulated rainwater will rise to the ground and form groundwater. Due to the tree arrangement of the rainwater pipeline system, it is determined that such pressure flow drainage difficulties and water accumulation conditions are limited to the upstream pipeline, and have no effect on the downstream pipeline of the pipeline, other pipeline pipelines in the system, and adjacent stormwater pipeline system pipelines. , can not make more use of the gap volume generated in other line pipes and adjacent rainwater pipe systems in the system.
