[0004]

As described above, the conventional water collecting basin of this type is formed in a cylindrical shape having a bottom portion and an opening portion at both ends in the axial direction, and the cylinder wall portion is opened from the bottom portion. Since it is a synthetic resin molded product with a shape in which the diameter gradually increases toward the section, earth pressure is applied to the water collecting basin during and after the construction of burying it in the ground, pushing up the water collecting basin upward. . Therefore, there is a problem that the water collecting basin floats.

Since the water collecting basin has a shape in which the diameter of the cylindrical wall gradually increases from the bottom toward the opening, that is, the shape of the area of the bottom is the smallest, it is installed in the ground during construction. It lacked stability and often resulted in improper placement such as tilted placement.

An object of the present invention is to provide a water collecting basin which is lightweight, easy to handle, and excellent in mass productivity.

[0007] Another object of the present invention is to provide a water collecting basin capable of minimizing the volume during storage and transportation.

Still another object of the present invention is to provide a water catchment basin which is prevented from rising due to earth pressure applied during and after burying 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 cause improper placement such as inclined placement.

[0010]

In order to solve the above-mentioned problems, the present invention is a water collecting basin including a basin body and an auxiliary member, wherein the basin body is formed of a synthetic resin and has an axial direction. It is formed in a tubular shape having a bottom portion and an opening portion on both end sides,
The cylindrical wall portion has a shape in which the diameter gradually increases from the bottom portion toward the opening portion, and has a stopper portion projecting within the outer diameter of the bottom portion near the bottom portion, and the auxiliary member is Has an outer diameter larger than the outer diameter of the bottom portion, and is attached to the bottom portion side by the stopper portion.

[0011]

[Function] Since the basin body is made of synthetic resin and is formed into a tubular shape having a bottom and an opening at both ends in the axial direction, it is lightweight, easy to handle, and excellent in mass productivity. Is obtained.

Since the cylindrical main body has a shape in which the cylindrical wall portion has a diameter that gradually increases from the bottom toward the opening, a large number of them are sequentially inserted inside and stacked without an auxiliary member attached. The volume during storage and transportation can be minimized.

Since the sill body has a stop portion, the auxiliary member has an outer diameter larger than the outer diameter of the bottom portion, and the auxiliary member is attached to the bottom portion side of the sill body by the stop portion, so that it is buried in the ground. During and after construction, earth pressure is applied to the water collecting basin against the auxiliary member so as to press the water collecting basin downward. For this reason,
Lifting of the catchment basin is prevented.

Since the auxiliary member has an outer diameter larger than the outer diameter of the bottom portion, the receiving surface of the bottom surface is substantially enlarged by the auxiliary member. 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.
