Field of the Invention The present invention relates to a drainage channel for continuously draining rainwater or the like to form a drainage channel. 2. Description of the Related Art As a drainage channel for draining rainwater or the like, a drainage channel in which side grooves are continuously laid is used.
FIG. 5 is a cross-sectional view of a conventional gutter. A base concrete 10 is cast on crushed stone 9, a bottom 11 is further formed of concrete thereon, and a drainage channel is formed with a gate-shaped gutter 1. [0003] When forming the bottom of a drainage channel with concrete, it is necessary for an operator to enter a narrow trench excavated and to perform concrete work, and the bottom is drained. It is necessary to take the drainage gradient. Therefore, there is a problem that work efficiency is poor. [0004] In addition, the drainage slope can be formed on a sloped road by adjusting the upper surface level of the drainage channel to the road slope and forming a bottom portion with a constant depth. However, if drains are provided on a road with no slope, or if drains are provided on a flat sports ground, they will be flat, so that the top of the drain will be horizontal and the bottom will not have a drain slope. Therefore, there is a problem that it takes time and effort to form the bottom while maintaining the drainage gradient. [0005] Therefore, the present invention is to eliminate the formation of a drainage gradient due to concrete work with poor work efficiency, and to perform the work of constructing a drainage channel in which the upper surface level is horizontal and a drainage gradient needs to be provided at the bottom. It is an object of the present invention to provide a drainage gutter which can be efficiently and easily performed without any problem. SUMMARY OF THE INVENTION A gutter for a drainage channel according to the present invention is a gutter for forming a drainage channel having a horizontal upper surface level and a drainage slope provided at a bottom portion. Comprises a gutter main body, a drainage gradient forming member and a lid, the gutter main body has an opening whose lower part is opened on both sides of the wall, and a step is integrally formed inside the lower part of both sides of the wall, In addition, the inner side of the wall on both sides is connected to the side
A lid hanging part with a downward slope on the drainage side
Is formed, and the lid is directed from the side to the inside of the lower surface.
The slope of the lid hook of the gutter body
A ridge supported on the surface is formed in the longitudinal direction of the gutter main body,
The drain gradient forming member has its upper surface inclined in the drain direction and inclined downward from both sides in the width direction toward the center.
A stepped portion on which the step portion of the side groove main body is placed is formed on both edges in the longitudinal direction, and the entire drainage slope forming member is fitted into the opening. FIG. 1 is an explanatory view of a gutter of the present invention, and FIG. 2 is a side view of the gutter of the present invention. In FIG. 1, the side groove main body 1 has two side walls 2.
And a lid holder 3 on the upper part thereof, and the lower part is open. A lid 4 is put on the upper part of the gutter main body 1. Gutter
The inside of the upper part of the wall on both sides of the body 1 is continuous on each side
And a lid hanging part with a downward slope on the drainage channel side
Is formed. The lid 4 faces from the side to the inside of the lower surface.
The slope of the lid hook of the gutter main body
Convex 5 that will be supported on the inclined surface is formed in the longitudinal direction of the gutter body, the lid by the ridges 5 is supported, Gatatsukazu even cars is through the top of the lid, it is possible to prevent the generation of noise it can. As shown in FIGS. 2 and 4, on the connection end face in the longitudinal direction of the side groove main body 1, an engaging projection 6 and an engaging A recess 7 is formed. FIG. 3 is a side view of the drainage gradient forming member of the present invention, and FIG. 4 is a view showing a state of a bottom slope when a drainage channel is formed by the side groove of the present invention. FIG. 1 shows the drainage gradient surfaces of the respective drainage gradient forming members superimposed for the sake of explanation. An opening at the lower part of the gutter main body 1 is
Gradient forming member 8 for forming a drain gradient at the bottom of
Is fitted. The upper surface of the drainage gradient forming member 8 is inclined
The drain slope 8a is formed to be inclined downward from both sides in the width direction toward the center . Each drainage gradient forming member 8
As shown in FIG. 3, when the height of the preceding drain gradient forming member 8 is gradually reduced to h3 <h2 <h1 as going in the draining direction, and when the gutter is continuously laid, , FIG.
A drainage gradient is formed as shown in FIG. The drainage gradient forming member 8 is prepared as a set of about 10 sheets, and the gutter main body 1 is prepared by sequentially increasing the height for each set of the drainage gradient forming member 8, so that it can be used for construction of a long drainage channel. Can respond. Steps 8b are formed at both longitudinal edges of the drainage gradient forming member 8, and stepped portions 2a formed inside the lower portions of the walls 2 on both sides of the gutter main body 1 are placed on the stepped portions 8. The drain slope 8a enters the inside of the gutter main body 1. An example of construction of a drainage channel using the gutter of the present invention will be described. When a drainage channel is formed in a place where there is no road gradient, a place where a gutter is to be buried is first excavated to form a trench.
The depth of the groove is a fixed depth from the ground level. Next, after the crushed stones are laid, one set of drainage gradient forming members is laid down so that the drainage gradient level decreases toward the drainage direction. Next, the gutter main bodies having the same height are placed on the drainage gradient forming member. When the drainage channel is long, the trench is dug down from the front, and the drainage gradient forming member is laid down so that the drainage gradient level is lowered toward the drainage direction. Is placed on the drainage gradient forming member. This makes it possible to form a drainage channel having a horizontal top surface and a drainage gradient at the bottom. According to the present invention, since the drainage gradient forming member having the drainage gradient surface is used, it is not necessary to perform concrete work for removing the drainage gradient. A drainage channel having a drainage gradient at the bottom can be efficiently formed.
