Abstract

PROBLEM TO BE SOLVED: To provide a storage and permeation tank of rainwater and the like which can change kind and number of columns according to an application and an overburden pressure on a ground.SOLUTION: Provided is a storage and permeation tank of rainwater and the like buried underground in which: a column unit is composed of a board body having a pipe-shaped supporting body for a column member disposed on its surface and a column member supported between the board bodies; the column unit is laid in a peripheral wall obtained by arranging water-bearing blocks, up to the same height as the peripheral wall for a column, to form a storage space; and the storage space is covered with a sheet.SELECTED DRAWING: Figure 8

Description

The present invention belongs to the technology of storage and penetration tanks such as rainwater.

For the purpose of suppressing the outflow of rainwater and the like, rainwater storage and infiltration facilities are widely used in which unit members made of plastic or the like are arrayed and filled in the basement, and the periphery is appropriately covered with a sheet. A method of supporting the ceiling with a pillar has also been proposed. JP2011-196097, JP2008-69568, JP2007-85116
There is a need for a method that can change the type and number of pillars in order to provide a predetermined strength according to the use on the ground and the earth pressure.

The present invention is a proposal for storing and penetrating rainwater or the like that can change the type and number of pillars according to the ground use and soil pressure.

The present invention is a storage penetration tank for rainwater or the like buried underground, and a column member and a column member support body of a tubular body are arranged on the surface in a peripheral wall obtained by arranging an aquifer block. It is a storage and infiltration tank for rainwater or the like, in which a storage space that is made of a board body and lays a pillar unit supporting a pillar member between the board bodies at the same height as the peripheral wall to form a pillar and is covered with a sheet.

The present invention provides a column unit by supporting a rod-like / tubular column member between disk bodies in which a tubular column member support is arranged on the surface in a peripheral wall composed of an aquifer block. The number of columns can be freely changed according to the required strength.

It is a key map showing a board. It is a conceptual diagram which shows a column member. It is a conceptual diagram which shows a pillar unit and its formation procedure. It is a conceptual diagram which shows the change of the kind and number of a board body and a pillar member. It is a conceptual diagram which shows the formation method of a pillar. The example of the coupling which connects a pillar unit up and down is shown. The example of the aquifer block which forms a surrounding wall is shown. It is a conceptual diagram which shows the storage space. It is a conceptual diagram of the storage penetration tank using a storage space.

Hereinafter, the present invention will be described in more detail with reference to the drawings.
As shown in FIG. 1, a column member support made of a tubular body is disposed on the surface of a rectangular flat plate.
Since the column member support is a tube, a rod or tube that can be inserted into the tube as shown in FIG. 2 and a tube fitted from the outside of the tube can be used as the column member. In addition, the cross-sectional shape of a tubular body and a column member is not limited to a circle.

FIG. 3 shows a procedure for forming the pillar unit. Place the panel with the column member support facing up, select the type and number of column members required according to the required column strength, and insert it into the column support of the panel or place the column member support in the column. Fit into the member.
Further, the board body is similarly inserted into or inserted into the pillar members from the upper part and overlapped to form the pillar unit so that the pillar members are fixed between the board bodies.
FIG. 4 shows an example of the type and number of plate members and column members.

As shown in FIG. 5, the pillar units are stacked so as to be the same height as the peripheral wall. At this time, the column unit is connected up and down using a joint shown in FIG.

The peripheral wall is formed, for example, using an aquifer unit in which the aquifers shown in FIG. 7 composed of a board and legs that open to the board are stacked with the legs facing each other. In this case, the aquifer unit and the column unit are preferably the same height and the same surface shape.

Columns are arranged in the peripheral wall to form a storage space shown in FIG. Although the ceiling part is already formed by the board body, the ceiling member which is a prior art can be further laid, or abandoned concrete can also be laid as needed.
The obtained storage space is wrapped with a necessary sheet as shown in FIG. 9 and collected. Additional facilities such as an orifice, an inflow pipe and an overflow pipe can be provided to form a storage permeation tank.

It can be used as an outflow control facility for rainwater.
