The present invention relates to a drainage canal structure, and in particular to a prefabrication type drainage canal structure which makes it possible to prevent a transformation and disengagement of a drainage canal in such a way that a plurality of drainage canal bodies each equipped with a waveform reinforcing unit are assembled in series, and a protection net is arranged over the drainage canal bodies which are buried underground, and a side reinforcing unit is installed into the ground so that a bottom foundation can be expanded, and the drainage canal bodies can be fixed in place on the ground. Trees, gravels, etc. can be prevented from penetrating into the drainage canal bodies thanks to the protection net. The drainage canal structure with an increased self-weight can be provided, which can keep it in place. Work and construction time can be saved because the drainage canal structure can be manufactured on the spot.
Drainage canals are installed in roads, mountains, rivers, etc. or in an agricultural drainage canal, an industrial complex, a housing complex, etc. in order to guide the flows of rain water and drainage water.
More specifically, the above mentioned drainage canals are installed at a bottom of a mountain ridge, a water guide canal, a rain water guide canal, etc. in an attempt to guide rain water or draining water.
The above mentioned drainage canals can be manufactured in a shape of blocks each with a certain length in such a way to cast concrete on the spot (hereinafter referred to a casting work on the spot) or to use a prefabricated concrete block or a synthetic resin.
In most of drainage canals, water is guided to flow inwards over the side walls of the drainage canals; however the water, sometimes, does not flow into the drainage canals due in part to the difference in the physical properties between the concrete and the synthetic resin.
If water flows long through the drainage canals, the synthetic resin may decompose and may be broken because the drainage canals made from the synthetic resin is directly exposed to sunshine.
SUMMARY OF THE INVENTIONAccordingly, it is an object of the present invention to provide a prefabrication type drainage canal structure which is invented so as to resolve the problems occurred when the conventional drainage canals heave due to rain water or the original ground moves away, and which makes it possible to prevent the loss of the original ground on which the drainage canals are constructed and to prevent the loss of the installed drainage canal structure. The drainage canal structure can be manufactured on the spot, and a simplified manufacture procedure and a stable assembling structure can be obtained in the present invention.
To achieve the above objects, there is provided a prefabrication type drainage canal structure equipped with a drainage canal body with a channel shaped vertical cross section and installed at a drainage carnal formed on the ground of a cutting area, which comprises a plurality of protrusion type waveform reinforcing units which are formed at regular intervals on at least one of an outer surface, an inner surface and both the inner and outer surfaces of the drainage canal body, a plurality of reinforcing units which are installed in a row at regular intervals traversing the interior of the drainage canal body, and a plurality of through holes which are formed at regular intervals at the tops of both sides of the drainage canal body.
The present invention is directed to a drainage canal structure whose transportation and installation work can be easy, and it can be easily assembled on the spot, and a transformation due to the pressure of surrounding soil can be prevented by forming a waveform reinforcing unit on an outer surface of a drainage canal body. When a drainage canal structure is installed at the drainage canal which is disposed underground, it is possible to prevent gravels from entering the drainage canal body by providing a protection net, thus preventing the clogging of the drainage canal body. The whole weight of the drainage canal structure can be increased by filling with soil the empty space from the outer tops of the drainage canals to the bottoms of the drainage canals including an assistant water way for thereby preventing the transformation and heaving of the drainage canals.
In addition, an eco-corridor for the sake of wild animals can be secured because a protection net is provided over the tops of the drainage canals, so the wild animals are not allowed to enter the drainage canal body, which leads to protection of wild animals.
The present invention will become better understood with reference to the accompanying drawings which are given only by way of illustration and thus are not limitative of the present invention, wherein;
The preferred embodiments of the present invention will be described with reference to the accompanying drawings.
The drainage canal structure according to the present invention has features in that a drainage canal structure can be manufactured on the spot and can be installed in an easier way as compared with the conventional art in which the drainage canal structure is manufactured at a factory and is transported from the factory to the spot of the construction.
In addition, the present invention makes it possible to guide the flow of water by installing a drainage canal structure at a drainage canal so as to prevent rain water or drainage water from flowing into the ground or onto the ground wherein the drainage canal where the drainage canal structure of the present invention is installed is provided at the ground near a cutting area, a river or an agricultural field so as to guide the flow of rain water or drainage water.

The side support bar 321 and the bottom support bar 322 of the outer reinforcing member 320 are fixed at both side surfaces and the bottom of the drainage canal body 200, respectively, for thereby more stably keeping the structure of the drainage canal body 200 (preventions of distortion and bending of the drainage canal body). A slope bar 23 is installed at a certain slope at one surface of the bottom support bar 322 in one surface of the side support bar 321 so as to provide a resistance force against the soil pressure at the outer sides of the drainage canal body 200 before and after the construction for thereby resolving the problems related with the soil pressure.
A plurality of outer reinforcing members 320 are installed at an outer surface of the drainage canal body 200 for thereby more stably supporting the drainage canal body 200.
The side support bar 321 of the outer reinforcing member 320 is vertically installed in consideration of the configuration of the drainage canal body 200; however it is obvious that the side support bar 321 of the outer reinforcing member 320 is sloped at a certain angle when both sides of the drainage canal body 200 are sloped at certain angles.
In addition, a plurality of the outer reinforcing members 320 are installed at an outer surface of the drainage canal. When it is installed at a drainage canal of a slope area, it is possible to increase the friction force with the ground thanks to the outer reinforcing member 320, so the drainage canal body 200 is not slipped or disengaged from the ground for thereby accurately installing the drainage canal body 200 at the drainage canal in the middle of the construction. In addition, it is possible to keep the drainage canal body 200 in place in the drainage canal after the construction.
