Description

Drain hole {DRAIN GUTTER FOR DRAINAGE STRUCTURE}

The present invention relates to a drainage side opening, and more particularly, to a drainage side opening having a function of inducing drainage to the surface subsurface rainwater during rainfall.

In Korea, most of the country is composed of mountainous terrain, and the country is narrow, and it is inevitable to develop mountainous areas according to industrialization and urbanization. Therefore, slopes are inevitably formed during the construction of roads, railways, or complexes, and damages are also increasing.

On the other hand, in a series of studies on slope collapse, rainfall is commonly known as a decisive factor that causes slope disaster physically and mechanically. When rainfall acts on the slope, rainwater flows on the slope to form surface flows, It is known to penetrate vertically to a certain depth (0.5 to 2m) and then move laterally to form subsurface flow.

Most slopes are unsaturated because they are above ground level.

When it is in an unsaturated state, negative pore water pressure is present inside the slope, thereby maintaining the stability of the slope. This negative pore water pressure is also called matric suction.

5 is a diagram illustrating deep and shallow destruction due to rainfall.

If the groundwater level is near the surface of the slope and the permeability of the slope ground is large due to cracks or joints, the entire slope is likely to be completely saturated when rainfall occurs. In this case, the stability of the slope drastically decreases according to the rainfall. Deep failures in the form of arcs are likely to occur.

On the other hand, when the groundwater level is located deep, it is difficult to saturate the entire slope, the permeability is low in unsaturated soils, and because of the water storage capacity between the internal gaps, it is possible to rainfall down to deep depths. Is difficult to penetrate and reach.

That is, the rainwater penetrated from the slope surface is moved to the inside of the slope while reducing the capillary absorption in the vicinity of the slope surface, the strength of the ground is weakened when the capillary absorption is reduced or extinguished due to the infiltration rain.

In addition, the groundwater level is rapidly formed temporarily even near the surface, and the ground strength is rapidly reduced as the pore water pressure is applied.

On these weakened slopes, the slope collapses as a result of continuous rainfall and penetration into critical depths where the stability of the slope cannot be secured. This type of decay occurs mostly near the surface of the slope, and thus forms a form of shallow failure or surfacial failure.

Traditionally, geotechnical engineering dealing with slope disasters has established stable analysis and disaster countermeasures that assume deep destruction. However, according to the recent researches since 2000s, slope collapse has occurred within 2.0m near the earth's surface. It needs a stable analysis of disasters and countermeasures against disasters.

The causes of shallow fractures are the penetration of rainwater through the earth's surface and the ground strength degradation due to the movement of infiltrated rainwater. In order to block the infiltration and movement of the infiltration water, slope design standards at home and abroad are to install a ridged drain on the top of the slope as shown in Figure 6a.

At this time, the ridge drain drains the surface flow flowing into the slope from the top of the slope, and serves to block the rain water from penetrating the surface.

However, as shown in FIG. 6B, when the right side of the drainage port is lost, a function of blocking the flow of the ground surface is lost, and a dangerous situation may occur instead of promoting penetration.

This phenomenon occurs because, as described above, when the rainfall occurs, the surface flow and the subsurface flow are formed because the subsurface flow promotes the soil loss on the side of the drain, thus preventing the soil loss on the side of the ridge drain. It is necessary to find out.

In addition, if the ground wetted by rainwater is not dried or drained in a short time, it may be inconvenient to use the place where people use frequently, such as sports grounds, parks, and residential complexes. There is a need.

The present invention has been devised by the necessity as described above, and an embodiment of the present invention has a function of inducing a flow of subsurface rainwater to a drain, and in particular, when installing a drain on a ridge, the soil on the side of the drain is an indicator of rainwater. It relates to a side outlet for drainage which can be prevented from being lost by the downstream flow.

According to a preferred embodiment of the present invention, in the side opening for drains comprising a bottom surface portion and a pair of side portions extending upwardly on both sides of the bottom surface portion to face each other, at least one of the top portion of the pair of side portions Is made of a mesh of metal or synthetic resin material, the space inside the net is filled with gravel, and the side surface for the drain is provided, characterized in that the surface underwater flows into the bottom surface through the net.

Here, it is preferable that the shape of the mesh is a shape in which the side part extended.

In addition, the side portion may be formed to be inclined with respect to the bottom surface portion.

In addition, the mesh may be integrally formed with the side portion.

According to the side opening for the drain according to a preferred embodiment of the present invention, the subsurface flow of rainwater is induced into the side through the mesh of the side portion located below the ground surface, accordingly in the case of the drain to be installed on the ridge Soil loss can be prevented, slope collapse due to shallow destruction can be prevented, and when installed in a playground, a park or a residential complex, it is possible to solve the inconvenience caused by weather conditions by draining the subsurface rainwater quickly.
