Description

Irrigation experiment facilities for road to analyze the optimal collection efficiency according to the shape of the road and to provide the drainage according to it

The present invention relates to a hydraulic test apparatus for a road that can analyze the optimal collection efficiency according to the shape of the road, and more specifically, to configure the actual road structure or shape and experiment the drainage state of the road surface water flowing thereon By providing a device that can be used, it is possible to suggest a way to improve drainage capacity according to the road structure and condition, and thus optimal car collection according to the type of road to prevent flooding or minimize flooding of the road. A hydraulic test apparatus for roads to analyze the efficiency and provide a drain accordingly.

In general, in Korea, a lot of damages are caused not only by flood disasters caused by heavy rains in summer but also by local heavy rains.

In addition, localized heavy rains frequently cause flood damage, especially in low-lying areas and low-water drainage and low-water drainage areas where river coastal or runoff increases rapidly.

In addition, the increase of the impermeable area due to the urbanization process further increases the inundation damage due to the change in hydrological characteristics such as the increase of the peak flow rate and the decrease of the peak flow time.

In addition, rainwater in urban areas is moved and drained through roads.

The road drainage system consists of side openings, waterways, collection wells, drainage pipes, drainage culverts, rain gutters and manholes installed on urban planning roads.

And the road drainage system includes not only the purpose of ensuring the stability of the road surface but also the function of drainage of outflow water flowing outside the road.

However, in the sewage facilities such as rain gutters installed near the road, the rainwater is not drained smoothly, and the road surface becomes stagnant, and the road surface water flows into neighboring residential districts, causing flood damage.

In addition, the stagnant road surface water may cause accidents due to slippage such as traffic jams and hydroplaning, and may cause road breakage by causing stripping and port holes in the pavement.

Flooding in road areas can also cause catastrophic effects on structures installed in underground spaces such as subways.

Therefore, the drainage capacity necessary to prevent flood damage and to maintain the stability of the road surface is selected in consideration of the type, size, traffic volume and year of the planned road, and the purpose of drainage and the location of the drainage facility for each drainage facility. When conditions and planned flow rates are exceeded, the size of the drainage system should be determined taking into account the extent and economics of the impact on the surrounding area.

In determining the size of these drainage facilities, it is inappropriate to apply the general rainwater reclamation method presented in other countries, considering the topography of Korea, which is mostly mountainous.

Considering these points, there is a need for reasonable drainage to protect the property of citizens from flood damage and to maintain the level of road service and traffic safety.

Therefore, it is necessary to analyze the collection efficiency of rain gutters and establish measures to reduce the flooding of urban floods by improving the rainwater rejection capability of the wet flooded areas by installing the rain gutters according to road conditions, proper size and management measures.

Therefore, the appropriate size, shape, and spacing of rain gutters are examined through experiments according to the change of road width, longitudinal slope and cross slope, and the ratio of rainwater efficiency decreases due to blockage of inlet through experiments. By suggesting the type of sink inlet, flood damage should be reduced by improving the rainwater removal capacity of urban sewer pipes.

For reference, look at the conventional rain gutter installation method as follows.

Rain gutters should be installed at the place where water is easy to collect along the road or at the lower end of the L-shaped opening. However, it is better not to install the pedestrian crossing and the entrance of the house as much as possible. If there is a distinction between the sidewalk and the roadway, the installation location shall be the boundary. If there is no distinction between the sidewalk and the roadway, the boundary between the road and the private land shall be established.

Rain gutters are clogged with inflows due to garbage or debris, which causes road flooding problems.

Therefore, it is necessary to change the structure to reduce the inflow of dirty materials and soil and to facilitate the cleaning, and to establish a countermeasure according to the change of the road slope due to road repair work.

For reference, the interval between the rain gutters is as follows.

According to the Basic Planning Guidelines and Design Standards of the Ministry of Construction, the installation intervals of rainwater gutters were suggested as less than one per 20m.In the sewage facility standard of the Ministry of Environment, rainwater gutters of road drainage were approximately 10 ~ 30m. It is suggested to install at proper intervals considering the installation criteria for each slope.

I. It is installed in the place where water near the road is easy to collect or at the lowest point in each corner, and at the lower end of the L-shaped side.

Analysis of Dwelling Efficiency due to Blockage of Lattice-type Rain Gutter

If rain gutters are blocked by gravel, soil, and other contaminants, the net area of the inlet decreases, causing the rain gutter inlet to fail to function and add to flood damage on the road.

Therefore, it is necessary to analyze the clogging phenomenon of rain gutter inlet for rational design and management of rain gutter inlet.

As a result of the survey, the clogging of rain gutters due to contaminants does not occur with a certain rule, so it is difficult to predict the net area reduction of the rain gutter inlet due to clogging. In addition, it can be seen that there are various kinds of transport goods.

1 is a perspective view of a conventional grid rain gutter inlet in use state, the rain gutter inlet 100 is installed in the inclined portion between the end of the driveway 200 and the sidewalk (300).

However, irrespective of the amount or flow of road surface water such as rainwater, or the state of the road, the rainwater bucket and the hall are uniformly formed in a constant size and in a certain direction, and thus there is a problem that efficient drainage according to the state of the road cannot be achieved. .

Need for improvement

First, as the longitudinal inclination of the road increases, the flow velocity of the rain gutter increases, and when the grate is installed in the direction perpendicular to the flow direction flowing into the gutter, water drainage occurs at the inlet of the gutter, so There was this decreasing issue.

Therefore, it can be seen that the collection efficiency increases when the flow direction and the grate flowing into the rain gutter inlet are installed in the same direction.

Second, as the lateral inclination increases, the flow width of the road decreases so that the rainwater flowing into the rain gutter flows to the curb side, and when the flow rate increases, the water flow phenomenon and the water shape of the water gutter on the curb side There was a problem that the collection efficiency is reduced.

Third, in general, the front collecting flow rate is higher than the side collecting flow rate of rain gutters, but when the inflow flow rate increases, the side collecting flow rate also increases, so that the water flows into the side and the direction of the declination is right, so that a lot of water is generated. Therefore, there was a problem that the collection efficiency is reduced.

Fourth, as a result of the field survey, clogging of the rainwater gutter inlet does not have any tendency, but there is a problem that clogging in the curb direction is more frequent.

If the rain gutter inlet is blocked in the curb direction, it can be seen that there is a need for improvement as it can be seen that as the longitudinal slope of the road and the transverse slope of the sideways increase, the collection efficiency decreases significantly.
