The present invention relates to a sump for a drainage channel used to drain living water or rainwater by sinking into a boundary line of a car, a sidewalk, or a residential street, and in particular, a sump body is formed in a polygonal shape and the sump is deformed by external earth pressure. Earth and sand entering the sump with rainwater and so on. The present invention relates to a filter net for filtering dirt, formed integrally with rainwater inlets and outlets, and welded to the sump body to prevent separation and breakage of the filter net.

Conventional water collection tanks were formed of cement concrete or synthetic resin materials, but when constructed with cement concrete, the construction period is long and the loss of materials is uneconomical and difficult to install. If it is not installed, a large amount of rain or sewage or sewage is discharged into the sewer pipes to block the sewers, or when the sewer pipes have been buried for a long time, the sewage and sewage are stacked inside the sewer pipes and the sewer pipes are blocked.

Therefore, when a large amount of water flows into the sump at a time, the water is not discharged into the sewer pipe and overflows to the road, causing inconvenience to traffic of vehicles and people, as well as excessive difficulty and expense in repairing the sewer pipe.

And in the case of the sump made of synthetic resin, the filtering net is composed separately from the sump main body, so that the filter net is frequently separated and broken from the sump because the filter net is combined with bolts or screws. Since the shape is simply formed in a square or formed in a circle or a shape, the shape is easily deformed by external earth pressure, or the collection tank is easily broken.

The present invention has been made in order to solve the above-mentioned general drawbacks as described above to prevent the deformation or breakage of the circular shape of the main body of the sump to the maximum, and to prevent the filtering net from being separated from the sump.

Features of the present invention for achieving the above object is to slightly project both sides of the central portion of the sump to the outside, the filter net is formed integrally with the connecting pipe welded to the sump as described in detail according to the accompanying drawings as follows. same.

1 is a perspective view showing a state in which the lid is separated from the water collection tank of the present invention, FIG. 2 is a plan view without the lid, and FIG. 3 is a cross-sectional view of the water collection tank of the present invention cut into the longitudinal section.

As shown, the upper part is opened so that the lid 7 can be covered, and the centers of the two side surfaces 5, 5 'facing each other in the sump body 2, which are configured to be inclined in a light-receiving side shape, in which the front and rear sides are inclined. So that its cross section is " Of the collection tank 1 in which the connection pipe 3 is melt-welded 6 to the lower side thereof, and the filter net 4 is integrally formed with the connection pipe 3 on one side of the connection pipe 3. In the accompanying drawings, reference numeral 8 denotes a drain pipe.

The present invention as shown in Figure 6 may be used as a gutter and sewage by making the height of the connecting pipe (3) different. And it can also be carried out by forming the connecting pipe (3) on only one side.

When explaining the effect of the present invention as shown in Figure 4 when the collection tank (1) is buried in the boundary of the car, sidewalk or road, that is, the space is buried in concrete or soil around the collection tank (1) When the compacting operation is performed, the left and right sides 5, 5 'of the water collecting tank 1 are pushed into the inside or the water collecting tank 1 is destroyed by the earth pressure which is compacted. It can be seen that the earth pressure structure) is much stronger.

And, by welding the connecting pipe (3) formed integrally with the filter net (4) to the sump body (2) it is possible to prevent the filter net (4) from being separated or broken.

Claims (1)

The inner periphery of the main body 2 having the lid 7 inserted and detachable at the upper end and protruding outwardly from the central portions of the opposite side surfaces 5 and 5 'is formed in the upper and lower narrow shapes. In the drainage collecting tank (1) in which the connecting pipe (3) is fixed at a lower predetermined position, the connecting pipe (3) is characterized in that the filter net (4) is integrally formed on one side thereof and welded to the main body (2). Drainage tank for drainage.
