The present invention relates to a prefabricated vegetation drainage channel and a construction method thereof.

Generally, the drainage path is a structure for smoothly draining rainwater or groundwater by being installed on both sides of the road, preventing soil loss of soil ridges, and underground underground culverts.

Conventional drainage has a cast-in-place concrete structure for constructing major components directly on site, a pre-cast structure for pre-fabricating the main components and then installing these components on-site, and a PE structure using unit parts formed of plastics. Widely used.

In the case of constructing the drainage path by site casting, reinforcing steel bars, installing formwork, placing concrete, and curing are difficult to construct, high construction cost, and difficult to repair.

And, in the case of precast construction, the precast unit structure is easy to install, but when concrete structures are installed on the ridge, it not only damages the scenery but also causes problems in the movement of animals, which is not good for the ecosystem. In addition, the leakage occurs at the connection part of the unit structure, in particular, the curved part, which requires a separate structure for the connection of the unit structure.

In addition, the construction of the drainage channel with PE has the advantage of being light and easy to install, while there is a high possibility of being easily deformed or damaged by temperature change, and particularly, the structure is damaged or lifted due to the earth pressure around the rainfall. Is generated. In order to compensate for this, the method of pouring the floor concrete is adopted, but it is still difficult to reinforce the side has a very disadvantageous problem in terms of durability.

Recently, a steel connection structure by H beams has been used in constructing drainage channels, which are fixed to the ground and are inclined at both ends of the ground as shown in Utility Model Publication No. 2000-7246. And an H beam including a side portion having a long groove formed at each center in the longitudinal direction of the rear surface, a bottom plate formed in accordance with the shape of the base portion of the H beam and connected to the base portion, and both sides thereof as a rectangle in the side grooves of the H beam, respectively. It consists of a side plate inserted. According to this structure, since the H-beam and the bottom plate are continuously installed, the side plate is simply inserted between the H-beams, so that the parts can be produced at the factory and assembled in the field, so that the transportation is convenient and the assembly work is simplified. . However, after the construction, the H-beams are damaged by earth pressure, and the rust generation and twisting deformation of the H-beams formed of steel make it difficult to assemble the base plate or side plate made of concrete.

Accordingly, the present invention is to solve the above-mentioned problems, and to provide a prefabricated vegetation drainage and its construction method that is easy to transport and construction, and made of permeable concrete, so as to prepare in advance and assembled in the field. There is this.

As a technical configuration for achieving the above object, the present invention in the drainage is installed to drain rainwater or groundwater, etc., the bottom portion is made to have a 'ㅂ' shaped cross section by the water-permeable concrete and flowing water And a prefabricated vegetation drainage, characterized in that the side constitutes a drainage passageway of the water by blocks formed impermeable by spraying with water, cement and polymer mixtures.

In addition, the present invention is a method for constructing a drainage channel to drain rain water or ground water, the process of leveling by laying the auxiliary base layer, sand, etc. after the excavation, and the water permeability having a conventional composition on the excavated site The process of installing blocks of 'ㅂ' shaped sections made of concrete and impermeable by spraying with water, cement and polymer mixtures, and permeable permeability provided with the usual composition between the blocks The process of installing an open block of 'U' shaped cross section, made of concrete and formed impermeable by spraying the mixture, spraying soil on the upper part of the block and inducing vegetation such as grass on the part. Construction of prefabricated vegetation drainage, characterized in that it comprises a step of finishing the work by performing the work to It depends on the maryeonham.

Hereinafter, the present invention will be described in more detail.

Figure 1 is a perspective view showing the construction of the prefabricated drainage in accordance with the present invention.

The floor 10 is constructed and formed by in-situ concrete by a conventional method. The bottom 10 may have a shape in which both ends slightly protrude upward, and the bottom 10 may be omitted as necessary, for example, in the case of flat.

Block 20 is placed on top of the bottom 10, the block 20 is manufactured to have a roughly 'ㅂ' shaped cross section.

As shown in more detail in FIG. 2, the block 20 has a main body 22 having a '?' Shaped cross section and a protrusion 24 formed to have a shape slightly protruding upward at both end portions of the main body 22. ).

The block 20 is made of permeable concrete having a conventional composition, it is preferable to add ocher, germanium, charcoal and the like to the permeable concrete in consideration of the vegetation and the surrounding environment.

The block 20 is formed of an impermeable portion of the outer surface. The water impermeability is formed by spraying a mixture of water, cement and polymer with a spray on the surface of the block 20, and the mixture may be ocher, germanium, charcoal, or the like.

Spraying the mixture on the surface of the block 20 may be done directly while installing the block in the field, and if necessary, the mixture may be sprayed in advance on the necessary portion.

At this time, the portion of the surface of the block 20 is formed impermeable may include a portion to block the water permeation, for example, the lower portion of the water flowing, and the entire portion of the side or side adjacent to the lower portion.

In particular, in the case of constructing the bottom 10, the permeability of the area enclosed by the bottom 10 need not be removed, and in the case of not constructing the bottom 10, the mixture is formed on the lower surface of the block 20. Spray to remove permeability.

In addition, the part from which the permeability is removed may vary depending on the characteristics of the place where the block 20 is installed. For example, when one side of the block 20 is located on a hill or a mountain side, the part is only as low as possible from the bottom. Impervious and other parts are made permeable so that water coming down from the hill or the mountain side can be introduced into the inside of the block 20, while the other part not located on the hill or the mountain side is to the highest part from the bottom. It is impermeable.

In addition, a plurality of blocks 20 are installed to be in close contact with neighboring ones along the bottom 10, and between the blocks 20, it is preferable to block the gap by spraying the above mixture with a spray. In particular, when the block 20 is constructed along a curve, a gap is formed between the block 20 and the block 20, and the gap is filled as well as neighboring blocks by spraying the mixture on the gap. May have a function of adhering to each other.

In addition, it is preferable that an open block 30 is installed between a certain number of blocks 20, and the open block 30 is formed to have an approximately 'U' cross section as shown in more detail in FIG. .

Of course, the open block 30 is also made to be water-permeable, and the above-mentioned mixture is sprayed so that the part corresponding to the water-impermeable part of the block 20 is impermeable.

When the open type block 30 is installed between the predetermined number of blocks 20, the inside of the block 20 is easy to clean, and when the porous voids of the block 20 are preferred, it is easy in terms of the action.

Then, when the soil is sprayed on the upper portion of the block 20 constructed as described above and the vegetation is induced to the portion, the selected portion of the upper and side portions of the block 20 is formed permeable, so that the settlement of the vegetation is relatively easy.

In addition, when the vegetation is settled on the upper portion of the block 20, not only becomes a free movement path of the animal, but also when the animal enters the inside of the block 20 through the open block 30, the upper portion of the block 20 is porous. It is made of a permeable having helps the animal easily escape through the open block 30 without feeling the fear.

When the drainage channel is constructed with a block and an open block having the upper part permeable and the lower part impermeable, water is freely flowed through the upper part into the drainage channel, and the water thus flowed through the bottom of the impermeable part. May be discharged.

Hereinafter, a method for constructing a prefabricated vegetation drainage passage according to the present invention will be described.

First of all, in order to construct the drainage, the trench is laid and the auxiliary base layer, sand, etc. are leveled.

Next, the floor 10 is constructed in the site-cast concrete by a conventional method in the excavated site. This process may be omitted if necessary, and the water impermeable portion of the block 20 and the open block 30 to be described later may vary depending on the construction of the floor 10.

Subsequently, blocks 20 are installed along the bottom 10 and these blocks 20 are continuously placed so that neighboring ones are in close contact with each other.

At this time, the block 20 is formed of the required portion is impermeable, this impervious portion may be formed by spraying the mixture on the surface of the block 20 in the field or may be formed in advance.

In addition, when the bottom 10 is constructed, the lower portion of the block 10 may maintain the permeability, because the rain 10 or ground water is blocked by the bottom 10 to pass through. And, if the bottom 10 is not constructed, the lower portion of the block 10 should be formed impermeable.

Preferably, the gap between the blocks 20 is sprayed by spraying the mixture.

In addition, the open type block 30 is positioned between a predetermined number of blocks 20, in detail, a portion into which rainwater is introduced.

Subsequently, the work is completed by spraying the soil on the upper portion of the block 20 constructed as described above and inducing vegetation such as grass to the site.

As described above, according to the prefabricated vegetation drainage and the construction method thereof according to the present invention, it is possible to construct an eco-friendly drainage that is easy to vegetation by forming a drainage passage with a block having an upper permeability and an impermeable bottom portion.

In addition, an open block is installed between a predetermined number of blocks to facilitate the cleaning of the blocks.
