Abstract

An eco-friendly ridge gutter is provided to effectively drain the rainwater after collecting rainwater and to have eco-friendly effect. An eco-friendly ridge gutter has a water collecting dummy ditch installed in the lower part of an open channel installed in a slope. A vertical drain pipe(6) is connected from the open channel to the dummy ditch to drain water. The face in which water flows in the open channel is reinforced with an erosion prevention net(8) and a lattice frame(1).

Description

Eco-friendly diversion drain {Nature-friendly diversion drain at top of slope}

The present invention relates to a drainage path (hereinafter referred to as a ridge side opening) for guiding water from a ridge of an incision for opening a road or a railroad to a starting point of the incision. Conventionally, cast-in-place concrete type precasting, precast type plastic opener, and blood opener have been applied. Among them, cast-in-place concrete type is used the most.

The cast-in-place concrete casting has many difficulties in construction.

Above all, since the excavation machine has to work on a high incision site, the safety risk is very high, concrete pouring on the slope is not easy and form assembly is also very difficult to construct. Even after the construction was completed, the rainwater did not flow into the clearing well and the backfilled soils on both sides of the clearing were eroded.

In order to improve the difficulty of construction, the precast type or plastic or concrete PC is manufactured and installed. However, even in this case, the backfill soil is lost and the bottom is often eroded and damaged.

The goal is to create a vegetation that can serve as a vegetation so that rainwater, which is the role of ridges, can be drained and drained naturally.

In the existing ridged side, it was not possible to make a pledge with a machine due to the condition of backfilling in the burrow to install concrete casting or precast removal. In addition, when the water is saturated, the water is settled down and the water flows to the part, and the rainwater does not enter into the open space, but erodes to the side.

In addition, it was uneconomical because the amount of rainwater collected into the ridges was very small compared to the capacity of the sides.

This problem was solved as follows. In the drainage method of the ridge, the perforated pipe (2) wound around the filter material is laid at the deepest part of the trench to collect rainwater.In the backfill, the permeability coefficient is relatively relatively from the deepest to the half height of the perforated pipe (2). Filled with less soil (3), the upper part of the well-pitched soil layer backfilled into the U type (4) to allow the water flowing through the open water into the perforated pipe (2) to be drained. That is, it is a ridge side opening of the form which installed the catchment blind mare 12 in the lower part of an open space.

When the blind culvert is also installed in the lower part of the existing precast or cast-in-place concrete ducts, even when rainwater penetrates into the backfill part, it is collected into the blind pit (12) to prevent erosion.

When the slope is urgent, the reinforcement is reinforced with an erosion prevention net 8 or a grid 1. Erosion prevention net 8 or vegetation mat or lattice frame 1 is installed to prevent erosion of open spaces.In case of high flow rate or steep slope, a combination of erosion prevention net 8 and lattice frame 1 is installed. do. The grid frame (1) is a grid of top and bottom open elements are integrated to form a projection (7) at the intersection of the grid to facilitate the attachment of the wire mesh and the cross section is characterized by the function of preventing the erosion because of the open shape have. As a construction method, a U-type lattice frame (1) is installed on the top of the blind lamella (12), which is suitable for the cross-sectional shape of the lattice frame (1), and the vegetation base material (10) is attached thereto. . The vegetation base material is prevented from being eroded by the grid 1 even when water flows. Attaching the net to the grid projections 7 can further supplement the function of preventing erosion, which is selectively applied depending on the importance of the structure and the speed of the flow rate.

Erosion prevention net (8) and the grid frame (1) can be fixed by hammering the pin (9) to the ground by hammering or fixed by perforation.

Vegetation base material (10) is a kind of compost mixed soil used for slope recording is installed by air or when the gradient is gentle when the vegetation base material (10) to fill the grid frame (1) and is constructed by construction.

In order to prevent the erosion, the open water is connected to the vertical drainage pipe (6) from the open water (11) to the blind rock (12) in order to prevent the erosion. The position of the drain pipe 6 is installed at regular intervals or where the same number of water in the gradation is changed, so that the rainwater flows to the blind pit 12 located in the lower part of the lagoon.

The vegetation of the open garden should select well-growing plant seeds even when it is wet. The dry kiln which is dried during the dry season uses the vegetation seed on the general slope.

Existing ridge sideways could not be compacted by machines due to the narrow space in the trench for installing concrete casting or precast separation, but the environment-friendly ridge side is easy to install because there is no process like concrete placement. . In addition, when the water is saturated, rainwater is not introduced into the watershed, but water flows into the submerged backfill portion, so that the water is eroded to the side. In order to remedy these shortcomings, it is easy to make compaction by installing blind culverts for drainage, to prevent rain from being eroded by leading rainwater to the culverts, and to make the clearing itself green.

When explaining the embodiment using the drawings in the order of construction,

Digging a Ditch on a Ridge of the Incision

Laying the perforated pipe (2) wound with a nonwoven fabric (5) or filter material on the trench surface

Step 3 to backfill with soil having a relatively small permeability coefficient up to 1/2 the height of the perforated pipe (2)

A step (4) of backfilling into a cross-sectional shape of the lattice frame (1) up to the upper end of the perforated pipe (2) with a granulated soil that can act as a filter

Step of installing the U-shaped grid frame (1)

Fixing the U-shaped grid frame (1) with a fixing pin (9)

Mounting the vegetation base material (10) mixed with seeds to the grid (1)

Step of installing the erosion prevention wire mesh (8)

Fixing the erosion prevention wire mesh (8)

Eco-friendly ridge side mouth

In the construction step, the erosion prevention wire mesh 8 may be installed or omitted depending on the steep slope and the mild slope of the ridge side opening, and the fixing pin 9 used for fixing the U-shaped grid may be added or subtracted. .

Determine the size of the blind culvert by dividing a large amount and a small amount of water flowing into the open duct, and if necessary, connect the duct with a vertical open tube (6) to the bottom of the clear duct (12) and the grid (1) By doing so, the water flowing into the open space (11) can be easily introduced into the blind.

The vertically open tube 6 is advantageously installed at an inflection point where the gradient of the gamut changes from steep to mild incline.
