Description

Drainage treatment of roads {METHOD FOR DRAINAGE OF ROAD}

The present invention relates to a wastewater treatment method of a road, and more particularly, in order to smoothly handle a large amount of rainwater in case of heavy rains in summer, rainwater in a roadway is first drained, followed by a rainwater pitched to the sidewalk. The present invention relates to a road drainage treatment method configured to prevent a backflow phenomenon of the drainage and to enable a smooth drainage flow.

In general, roads are divided into driveways and sidewalks, and rainwater generated on the roadways and sidewalks is transferred through concrete drainage channels formed in the driveways and sidewalks.

That is, the rainwater generated in the roadway is transferred to the vertical drainage pipe through a drainage hole installed to match the road surface of the roadway, and the rainwater generated in the sidewalk is transferred to the vertical drainage pipe.

However, when heavy rain pours in a short time due to seasonal influences, such as in summer, there is a problem that flooding the drainage pipes overflows due to the large amount of rainwater flowing into the drainage pipes at the bottom of the driveway. Currently, most roads are divided drained to separate rainwater and sewage.

In addition, in the case of a new road, it can be said that most of the construction of a suitable concrete drainage channel using the numerical value of annual precipitation.

1 is a view showing the state of the sidewalk drainage treatment of a general road, the road R is composed of a sidewalk 10 and the driveway 20, the sidewalk 10 is a sidewalk boundary stone 12 and the driveway boundary stone 22 The sidewalk block 14 is installed between the pedestrians pass through the road, the driveway 20 is a road in which the vehicles run in a structure paved with asphalt in contact with the driveway boundary seat 22 and the el-shaped side door 24. .

The elbow side mouth 24 formed by a structure in which the sidewalk 10 and the driveway 20 are distinguished and the roadway boundary stone 22 is stacked on the upper part is formed in a structure through which the rain receiver 26 penetrates, The drain 26 is connected to the drainage connection pipe 28 on the lower side, and the drainage connection pipe 28 is coupled to the vertical drainage pipe 50 at the other end.

The storm receiver 26 is a concrete product and a plastic product is used, most of which is composed of a structure that is seated using a plastic product, the storm receiver 26 is a drain cover 40 is installed on the top road ( It prevents the inflow of foreign substances generated in R).

The vertical arrows in the drawing indicate rainwater, that is, a state in which heavy rain pours, and the horizontal arrows indicate a state in which rainwater is collected from the sidewalk 10 and the driveway 20 to the rainwater receiver 26.

A sand layer S is formed below the sidewalk block 14, and a nonwoven fabric 30 is installed below the sand layer S to support the sand layer S.

The road R having the above-described structure has excellent rain generated on the sidewalk 10 and the roadway 20, that is, when heavy rain occurs during the summer season. All are poured into the storm receiver 26, and if the amount of rainwater is greater than the capacity to be drained, the rainwater overflows to be accumulated on the driveway 20 has a disadvantage that many problems occur.

Particularly, the present situation is that the drainage structure using the roadway boundary stone 22 is being developed and constructed, but it is a reality that the large-capacity rainwater cannot be smoothly processed due to the overall structure. Although there is a structure in which a nonwoven fabric is installed to adjust the level, in reality, when a large amount of heavy rain is poured, it is difficult to expect a smooth drainage function, and rainwater penetrates into the lower ground so that the sidewalk is broken or the sand layer constructed at the bottom of the sidewalk block is settled. As a result, many difficulties occur in traffic, such as the difference in the height of the sidewalk block.

In addition, the products using the roadway boundary stone 22 and the nonwoven fabric have a complicated structure in many ways, and thus there is a problem in that installation and fabrication are difficult and thus weakening competitiveness.

In order to solve the above problems, the present invention provides a method in which the rainwater generated in the roadway is pretreated and then the rainwater generated in the sidewalk is treated with a time difference, so that The purpose of the present invention is to provide a wastewater treatment method for a road that has a smooth structure for installation and fabrication as well as for smooth treatment.
