Abstract

PROBLEM TO BE SOLVED: To provide a new unit member used in restraining an outflow of rainwater.SOLUTION: In this invention, unit members, in which a plurality of blocks with a vertically stackable shape are arranged in a linear manner by ribs, are built up like a parallel cross in the underground by stacking block portions of the unit members, so as to form a structure. And a surrounding area of the structure is covered with a floor material, a ceiling member and a wall material to form a storage space, and the storage space is coated with an appropriate sheet to form a storage tank or an infiltration tank. Thus a facility for restraining an outflow of rainwater and the like is provided.

Description

The present invention belongs to a unit member used for construction of a rainwater outflow control facility and a rainwater outflow control technology using the unit member.

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. For this purpose, various differently shaped unit members are disclosed in, for example, Japanese Patent Laid-Open Nos. 62-101097, 62-126179, 9-296486, 10-252108, 10-115778, and 11-43971. And proposed and used in JP-A-11-222886. In either method, the unit members are arranged in the basement, the perimeter is wrapped with a water-permeable or water-proof sheet, and a permeation / storage facility for storing rainwater or the like in the internal space is provided.
There is a proposal of a new unit member to replace those unit members.

This invention exists in the proposal of the new unit member used for the outflow suppression of rainwater.

The present invention is a structure in which a plurality of blocks having a shape that can be stacked up and down are arranged in a straight line with ribs, and a block structure of the unit members is stacked in a basement-like structure in a basement, and This facility is a facility for controlling the outflow of rainwater, etc., where the surroundings of the structure are covered with floor materials, ceiling members, and wall materials to form a storage space.

The present invention is a structure in which a plurality of blocks having a shape that can be stacked up and down are arranged in a straight line with ribs, and a block structure of the unit members is stacked in a basement-like structure in a basement, and Since the facility is an outflow control facility for rainwater and the like, which is covered with flooring, ceiling members, and wall materials around the structure, the load is supported by the block, so the strength is increased.

These are the conceptual diagrams which show the example of the unit member which is this invention. These are the conceptual diagrams which show the other example of the unit member which is this invention. These are the conceptual diagrams which show the example of the structure which assembled the unit member. These are the conceptual diagrams which show the other example of the structure which assembled the unit member. These are the conceptual diagrams which show the storage space which gave the top material of the structure, the floor material, and the wall material. Shows an example of using the storage space as rainwater outflow suppression.

Hereinafter, the present invention will be described in more detail with reference to the drawings.
As shown in FIG. 1, the unit member of the present invention has a shape in which a plurality of blocks having holes provided symmetrically in the vertical direction are linearly arranged with ribs. 1a is a plan view, FIG. 1b is a cross-sectional view along the line AA ′, and FIG. 1c is a side view. The block portion is shown in the figure as a rectangular parallelepiped having a square top surface. The block portions are linearly connected by ribs.

The block is provided with a hole opening on the bottom surface of the top surface, a protrusion for engagement, and a recess. In the figure, the hole is tapered so as to narrow toward the center. In the drawing, the hole portion can be reinforced through an iron bar or the like when the unit member described later is assembled so as to penetrate and increase the storage rate. When it is used as a block for suppressing outflow, there is no need to have a hole.
The protrusions and recesses provided at the top and bottom of the block are provided at positions where the unit members are engaged with each other when the unit members are assembled in a cross beam shape. The existing engagement part which can fix a block not only to this protrusion recessed part but up and down can be used.
The shape of the block portion is also square, but when the unit members are assembled in a cross-beam shape, the shape may be any shape that can be assembled without deviation so that the central hole portion is arranged in a straight line when the block portions are stacked and assembled. . A square or a circle is particularly preferable.

The block portions at both ends of the unit member shown in the figure are halved so that the shape of the block is square when the unit members are arranged in a straight line.

FIG. 2 shows another example of the unit member. 2a is a plan view and FIG. 2b is a cross-sectional view. The difference from the unit member of FIG. 1 is that the shape of the block is a cylinder and that the blocks at both ends of the unit member are not divided in half but remain a cylinder.

FIG. 3 shows a structure in which the unit members shown in FIG. A state in which the protrusions and recesses, which are joint portions provided in the block portion of the unit member, are stacked in three rows, one row, and five layers in height is shown. 3A is a plan view, and FIG. 3B is a cross-sectional view taken along the line A-A ′. By piling up in the form of a cross-girder, water flows freely into the structure.

FIG. 4 shows a structure in which the unit members shown in FIG. A state in which the protrusions and recesses, which are joint portions provided in the block portion of the unit member, are stacked in three rows, one row, and five layers in height is shown. 4A is a plan view, and FIG. 4B is a cross-sectional view taken along the line A-A ′. By piling up in the form of a cross-girder, water will flow freely into the structure.

FIG. 5 shows a state where a storage space such as rainwater is constructed by arranging top materials, floor materials, and wall materials around the top, bottom, and surroundings of the structure.

FIG. 6 is a conceptual diagram illustrating an example in which the storage space is used as a rainwater outflow suppression facility.
Wrap around the storage space with a sheet according to the purpose, and use it as a storage facility or infiltration facility for rainwater. When installing in a place where the groundwater level is high, cover the bottom surface, surroundings, and if necessary, the ceiling with a waterproof sheet so that groundwater does not enter the storage space. In addition, for the purpose of infiltrating underground, it is covered with a water-permeable sheet to prevent soil and sand from entering the storage space, and rainwater temporarily stored in the storage space is infiltrated into the soil.
The usage method of this unit member is not different from the block used for the construction of the conventional outflow control facility.

Furthermore, a mud basin, an orifice basin and an inflow / exhaust pipe according to the purpose of use are provided and used as a rainwater outflow control facility.

It can be used as a storage tank, a permeation tank, or a storage tank for effective use of rainwater, which is a rainwater outflow control facility.
