Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a water collecting basin used for rainwater.

[0002]

2. Description of the Related Art A water collecting basin of this type is buried above ground and used for receiving rainwater from a gutter. For this type of conventional water collecting basin, a synthetic resin molded product that is lightweight, easy to handle, and excellent in mass productivity is often used.

As the water collecting basin, there are known a taper type in which the diameter gradually increases from the bottom toward the opening, and a stray type in which the diameter is substantially constant between the bottom and the opening.

[0004]

Among the above-mentioned conventional water collecting basins, the taper type is capable of minimizing the volume for storage and transportation by inserting a large number of them into the inside and stacking them. There is an advantage. However, since the cylinder wall has a shape in which the diameter gradually increases from the bottom toward the opening, earth pressure that pushes up the catchment basin upwards during and after the burial in the ground There was a problem that the water collecting basin floated up when it was added to the basin.

Further, since the cylindrical wall portion has a shape in which the diameter is gradually increased from the bottom portion toward the opening portion, that is, a shape in which the area of the bottom portion is the smallest, the installation stability during construction for burying in the ground is improved. There were many cases of incorrect placement such as chipping and slant placement.

[0006] The straight type water collecting basin does not have the above-mentioned problem, but it cannot be stacked by sequentially inserting a large number of pieces. For this reason, there is a problem that the volume during storage and transportation increases and it is difficult to handle.

[0007] An object of the present invention is to provide a water collecting basin which can minimize the volume during storage and transportation.

[0008] Another object of the present invention is to provide a catchment basin which is unlikely to rise during and after the construction for being buried in the ground.

Still another object of the present invention is to provide a catchment basin which is excellent in installation stability during construction for being buried in the ground and which is less likely to be erroneously arranged such as an inclined arrangement.

[0010]

In order to solve the above-mentioned problems, the water collecting basin according to the present invention has a basin body, and the basin body has a tubular shape, and the tubular portion is arranged in an axial direction. It has wall surfaces that are substantially parallel to each other, has a bottom portion and an opening portion at both end sides in the axial direction, the bore diameter changes at an intermediate portion in the axial direction, and the inner diameter on the opening side is the inner diameter and the outer It is slightly larger than the diameter.

[0011]

[Operation] Since the basin body is tubular and the diameter changes in the axial middle part, and the inner diameter on the opening side is slightly larger than the outer diameter on the bottom side, a large number of water collecting basins When storing and transporting the water, the water can be stacked by inserting the bottom side of the other water collecting tank into the opening side of the other water collecting tank. Therefore, the volume during storage and transportation can be minimized.

Since the inner diameter of the basin body on the opening side is slightly larger than the inner diameter on the bottom side, the inner peripheral surface on the bottom side projects stepwise due to the difference between the inner diameters. For this reason, when the bottom side of another water collecting basin is inserted into the opening side of one water collecting basin, the bottom of the other water collecting basin inserted into the inner circumferential surface of the bottom side protruding stepwise. Hits against. Therefore, the water collecting basins are not excessively inserted, which facilitates the work of extracting the stacked water collecting basins.

Since the cylindrical body of the basin body has a wall surface whose cylindrical portion is substantially parallel to the axial direction, earth pressure which pushes up the water collecting basin is not likely to be applied during and after the burying work in the ground. Therefore, the water collecting basin is prevented from rising.

Since the tubular body of the basin body has a wall surface that is substantially parallel to the axial direction, a relatively large bottom area can be secured, unlike the tapered water collecting basin. For this reason, the installation stability during the construction for burying in the ground becomes high, and it becomes difficult to cause an illegal arrangement such as an inclined arrangement.

1 is a front sectional view of a water collecting basin according to the present invention, and FIG. 2 is a sectional view taken along the line A2-A2 of FIG. The water collecting basin according to the present invention has a basin body 1. The container main body 1 has a tubular shape, and the tubular portion 10 has a wall surface that is substantially parallel to the axial direction, and has a bottom portion 11 and an opening 12 on both end sides in the axial direction. The caliber body 1 has a caliber that changes in the axial middle portion, and an inner diameter D1 on the opening 12 side is an inner diameter D2 and an outer diameter D3 on the bottom 11 side.
Is a little bigger than.

Since the caliber body 1 has a caliber that changes in the axial middle portion and the inner diameter D1 on the opening 12 side is slightly larger than the outer diameter D3 on the bottom 11 side, as shown in FIG. When storing and transporting the individual water collecting basins M1 to M4, for example, the bottom part 11 of the water collecting basin M2 is provided on the opening 12 side of the water collecting basin M1.
The sides can be inserted and stacked. Therefore, the volume during storage and transportation can be minimized.

Since the inner diameter D1 on the opening 12 side of the container body 1 is slightly larger than the inner diameter D2 on the bottom 11 side, the inner peripheral surface on the bottom 11 side is caused by the difference in both inner diameters (D1-D2). Project in steps. Therefore, for example, when the bottom 11 side of the water collecting basin M2 is inserted into the opening 12 side of the water collecting basin M1,
The bottom 11 of the water collecting basin M2 abuts on the inner circumferential surface of the water collecting basin M1 on the side of the bottom 11 protruding in a stepwise manner. Therefore, the catchment basin M2
Is not excessively inserted into the water collecting basin M1, so that the work of extracting the stacked water collecting basins M1 to M4 becomes easy.

Since the tubular body 10 of the basin body 1 has a wall surface which is substantially parallel to the axial direction, as shown in FIG. 4, the water collecting basin M is inserted during and after the burial in the ground G. It is hard to apply earth pressure that pushes up. Therefore, the lifting of the water collecting basin M is prevented. In FIG. 4, 3 is a lid, 4
Reference numerals 1 and 42 are pipes. The container main body 1 has a pipe connecting portion 13 at an intermediate portion in the axial direction of the tubular portion 10, and the pipes 41 and 42 are connected to the pipe connecting portion 13. The holes for connecting the pipes 41 and 42 are formed by using an appropriate opening device during field work.

Since the tubular body 10 of the basin body 1 has a wall surface that is substantially parallel to the axial direction, the basin body 1 is different from the taper type water collecting basin.
A relatively large bottom area can be secured. For this reason, the installation stability during the construction for burying in the ground becomes high, and it becomes difficult to cause an illegal arrangement such as an inclined arrangement. The holes for connecting the pipes 41 and 42 are formed by using an appropriate opening device during field work. Although not shown, by arranging a block having an invert inside the cell body 1, it can be used as another drainage cell such as a sewage cell.

The container body 11 can be formed by using an appropriate synthetic resin. When the basin body 1 is made of synthetic resin, it is lightweight and easy to handle, and a water collecting basin excellent in mass productivity can be obtained. However, concrete may be used instead of the synthetic resin.

FIG. 5 is a sectional view showing another embodiment of the water collecting basin according to the present invention, and FIG. 6 is a perspective view of an auxiliary member. In the embodiment, a stopper portion 14 that protrudes within the outer diameter of the bottom portion 11 is provided near the bottom portion 11. The auxiliary member 2 is the bottom 1
It has an outer diameter larger than the outer diameter of 1, and is attached to the bottom portion 11 side by a stop portion 14. The auxiliary member 2 has at least a pair of recesses 20 on the outer circumference on both sides in the radial direction. Recess 2
The number of 0s is arbitrary. The auxiliary member 2 can be made using a synthetic resin plate, a metal plate, or the like.

Further, the main body 1 has a stop portion 14, the auxiliary member 2 has an outer diameter larger than the outer diameter of the bottom portion 11, and is attached to the bottom portion 11 side of the main body body 1 by the stop portion 14. Therefore, as shown in FIG. 7, earth pressure F1 in the direction of pressing the water collecting basin against the auxiliary member 2 is applied to the water collecting basin during and after the work of burying in the ground G. Therefore, the water collecting basin is prevented from rising.

The stopper 14 shown in the drawing is provided with a plurality of two or more stoppers 14 at substantially equal intervals in the circumferential direction of the bottom 11, and each of them has a groove 141 that opens toward the outside. The auxiliary member 2 is formed in a ring shape having a hole 21 in its surface, and the inner edge of the hole 21 is inserted into the concave groove 141 and attached to the bottom portion 11.

Since the auxiliary member 2 has an outer diameter larger than the outer diameter of the bottom portion 11, the receiving surface of the bottom surface is substantially enlarged by the auxiliary member 2. For this reason, the installation stability during the construction for burying in the ground becomes high, and it becomes difficult to cause an illegal arrangement such as an inclined arrangement.

Since the auxiliary member 2 has at least a pair of recesses 20 on the outer circumferences on both sides in the radial direction, as shown in FIG. And band or rope R
The stacked water collecting tanks M1 to M4 can be bound together. Therefore, it is possible to reliably prevent the load from collapsing during transportation or storage.

The auxiliary member 2 has a notch 22 corresponding to the stopper 14 on the inner edge thereof, and is joined to the stopper 14 via the notch 22. When combining, the stopper 14 is provided at the cutout 22.
After inserting, the auxiliary member 22 is surface-rotated in either direction. As a result, the inner edge around the notch 22 enters into the concave groove 141 of the stopper 14, and the auxiliary member 2 is hooked on the stopper 14.
