Description

Novel centrifugal type anti-blocking rainwater inlet

Technical Field

The utility model relates to a drainage technical field, concretely relates to novel centrifugal prevent blockking up inlet for stom water.

Background

In recent years, due to various factors such as climate change and urban construction, urban waterlogging occurs frequently, and the life and property safety of residents is seriously threatened. In addition to the increase of extreme rainstorm weather, the phenomenon of urban waterlogging caused by the reduction of drainage capacity due to the blockage of a rainwater inlet and the siltation of a rainwater pipeline is also very common. The gully is the main accessory structure of urban drainage pipeline system, and is also the important component of urban road drainage. The gullies are located at the beginning of the urban drainage system, usually at a distance from the town roads, squares, street intersections and street gutters. The gutter inlet is the starting point of an urban drainage system and has the functions of collecting rainwater and intercepting dirt. Scientific and reasonable's rain inlet design of intercepting dirty can reduce rubbish such as silt and block up the rain inlet and cause the rainwater not to have the passageway way or cause road and low-lying area ponding to form the phenomenon that waterlogging spot hinders the traffic or damages the road, and rain inlet intercepting device is as road surface drainage pollution control facility, and its structural design is especially important, consequently when waterlogging control reasonable design updates the management maintenance pipeline, adopts LID, GSI measure, should regard the design of urban road rain inlet in the drainage pipe network design, carries out reasonable transformation to current rainwater outlet.

At present, most of rainwater inlet structures laid on roads have rainwater well grates on the top surfaces, rainwater inlet shafts below the rainwater inlet structures, rainwater branch pipes connected with rainwater wells at the bottoms, and a plurality of orifices on the rainwater well grates. When cleaning, fallen leaves and sand are easy to be brought into a rainwater well, and the silt carried by initial rainwater is easy to be deposited at the bottom of the rainwater well, so that a sewer is blocked, and a water-soaking point is formed in a rainy period. In order to reduce blockage and improve drainage performance, the rainwater grate needs to be opened regularly to clean garbage in the rainwater grate, time and labor are wasted, danger is caused, and accidents of death and injury caused by falling of personnel are caused for many times. The cleaning of the rainwater inlet on the road also greatly influences the smooth transportation and traffic safety of urban roads. Garbage such as leaves deposited in the rainwater port can ferment, decay and emit peculiar smell under the soaking of rainwater, pollute surrounding air, and can cause pipeline explosion and the like to cause great economic loss and adverse social influence.

Therefore, a novel rainwater inlet is urgently needed to be designed to solve the problem that the rainwater inlet is easy to block and inconvenient to clean.
