Description

Municipal drainage system

Technical Field

The invention relates to the technical field of municipal water supply and drainage, in particular to a municipal drainage system.

Background

At present, in municipal water supply and drainage design, municipal drainage systems are divided into three types: the system comprises a combined system for discharging rainwater, domestic sewage and industrial wastewater in one pipeline, a split system for discharging rainwater, domestic sewage and industrial wastewater in two or more pipelines respectively, and a closure combined system, namely constructing a closure main pipe, and arranging an overflow well at a closure position; the common old urban area mostly adopts a flow-stopping and converging system, while the new urban area mostly adopts a flow-dividing system, namely rainwater and sewage are discharged by a water pipe; it is known that sewage can be discharged only when the sewage reaches the expected index, rainwater and sewage are mixed in a combined system, the water treatment cost is high, rainwater in a separate system can be simply treated and directly discharged, and domestic sewage is discharged after sewage treatment. In the prior art, most of rainwater drainage system designs are concentrated on rainwater planning, terrain height, pipeline trend and other aspects, and the design aiming at impurity removal, reverse water prevention, safety and other aspects of the drainage system is fresh. The following problems in the prior art are urgently needed to be solved:

firstly, the well cover at the position of a pipeline is maintained, when rainwater is large in rainy season, the well cover at the position with relatively low terrain is easy to drain water, overflow and the well cover jack up are caused, pedestrians and vehicles fall off the pipeline to be maintained after observation is not facilitated, and great loss is caused due to the fact that the water quantity in the pipeline is large and the water flow is rapid; in the prior art, the invention discloses a municipal road well lid (CN106592643B) in China, which discloses a well lid, wherein the well lid can float upwards when rainfall and flood happen, and cannot float away when floating upwards, so that the safety of pedestrians is protected; although the safety problem has been solved to a certain extent, its effect of neglecting the maintenance mouth, and the project organization is complicated, and personnel are difficult to descend the trunk line and carry out the operation, and in addition, overflow the well lid when the rainwater is reversed the back, the well lid that floats is as the barrier, causes the potential safety hazard.

The rain grate at the sewer pipeline is a grating plate with simple long circular holes in a hollow manner, and sundries on the road, such as fallen leaves, waste paper, plastics and other solid garbage, easily enter the sewer pipeline along with rainwater, so that the main pipeline is blocked; in addition, when the rainwater is large, the rain grate at the relatively low terrain is easy to drain water, the water accumulation degree of the road surface is increased, and danger is caused; in the prior art, a rain grate with a culvert (CN208251294U) is disclosed in the Chinese utility model, wherein a two-layer filtering culvert is arranged below the rain grate, so that the sewer is prevented from being blocked to the maximum extent by two-layer filtering, and the operation burden of sanitation workers is reduced; the multifunctional filtering culvert has the defects that the capacity of the filtering culvert is limited, sundries are excessive, the rain grate is blocked when the filtering culvert is not cleaned in time, the drainage is not facilitated, and a reverse water preventing device is not arranged.
