Description

  The present invention relates to rainwater storage and infiltration facilities. More specifically, rainwater and other water on the road surface (hereinafter referred to as rainwater) is temporarily stored below the ground to avoid disasters caused by heavy rain and to facilitate natural water circulation. Infiltration facilities such as rainwater that penetrate into the interior have been developed. These facilities are used for storage using schoolyards, underground storage pipes, storage by underground adjustment ponds, rainwater infiltration, rainwater infiltration by infiltration trenches, etc., but the present invention stores and infiltrates such rainwater. Regarding equipment.

  Conventional infiltration facilities such as rainwater are more made of plastic than concrete. However, plastic products have the following problems. For example, when trying to control runoff in a limited area such as in an urban area, the infiltration facilities such as rainwater are inevitably deep, but the problem is the groundwater level and the rainfall If the groundwater level rises due to such factors, buoyancy tends to work in the plastic storage tank. Moreover, since it is weak to the load of a horizontal direction, when an uneven load is applied when refilling earth and sand, there also exists a fault that a load tends to concentrate on a joint part (refer nonpatent literature 1).

  In view of the above circumstances, an object of the present invention is to provide a storage and infiltration facility such as rainwater that can perform a storage and infiltration function over a long period of time without causing problems such as deformation damage due to load and floating due to groundwater.

A rainwater storage and infiltration facility according to a first aspect of the present invention is a rainwater storage and infiltration tank provided with an inner partition surrounded by an outer wall, wherein the outer wall and the inner partition are rectangular rod-shaped concrete made of porous concrete. The concrete block is constructed of blocks, and the concrete block is connected at both end portions thereof to a joint engaging portion for fitting the ends of the concrete block continuously provided in the same direction and the ends of the concrete block arranged in the orthogonal direction. It has the orthogonal engagement part which fits .
The rainwater storage and infiltration facility according to a second aspect of the present invention is the first aspect of the invention, wherein the outer wall is configured by stacking a plurality of concrete blocks in a vertical direction and continuously connecting in a plurality of rows in the width direction, The concrete blocks are arranged so as to be orthogonal to each other in adjacent upper and lower stages.
The rainwater storage and infiltration facility according to a third aspect of the present invention is the second aspect of the invention, wherein the concrete block is formed with a fitting convex portion that fits with another concrete block on the upper surface and fitted with another concrete block on the lower surface. wherein the engagement recess is formed.
Rainwater reservoir penetration equipment of the fourth invention, in the third invention, the concrete blocks, characterized in that the uneven surface is formed on the side surface.

According to the first invention, the following effects are obtained.
a) An outer wall and a partition can be constructed only by a combination of concrete blocks, and a larger water storage space can be secured by providing a long continuous connection. Moreover, since the specific gravity of the concrete block is heavy, there will be no inconvenience that the concrete block will rise even if the buoyancy at the groundwater level acts. Furthermore, since water permeability is given to the outer wall by using porous concrete, a water-permeable sheet becomes unnecessary when used in a permeation tank.
b) Since the engagement between the adjacent engaging blocks and the orthogonal engaging portions formed at both ends of the concrete block is difficult to disengage adjacent concrete blocks, the resistance to the external force is high and the function of the storage and permeation tank can be achieved for a long period of time. Moreover, the installation in the polygon which changed the shape not only in the quadrangle but two-dimensionally is possible.
According to the second aspect of the present invention, as a result of the partitioning being made orthogonal to each other in the adjacent upper and lower stages, a space is created between the upper and lower stages, and a continuous large internal space is formed. For this reason, even if the installation area is the same, a large amount of water can be secured.
According to the third invention, since the fitting convex part and the fitting concave part are fitted to each other, the free movement between the upper and lower adjacent concrete blocks is restrained, so that the outer wall and the partition are not broken even if they are stacked. Can be constructed as follows.
According to the 4th invention, since the unevenness | corrugation of the side surface of the concrete block used for the outer wall becomes resistance with respect to external forces, such as a vibration, in a ground, a tank structure does not collapse easily.

Next, an embodiment of the present invention will be described with reference to the drawings.
(Basic structure)
The basic structure of the rainwater storage and infiltration facility RP according to the present invention will be described with reference to FIG. The rainwater storage and infiltration facility RP of the present invention is a three-dimensional structure formed into a quadrilateral or other polygonal shape.
W is an outer wall, and is configured by stacking a plurality of square bar-like concrete blocks (hereinafter referred to as square bar blocks b) vertically and continuously in a plurality of rows in the width direction.
S is a partition and is constructed by stacking square bar blocks so as to be orthogonal to each other at adjacent upper and lower stages.
R is a lid, which is constructed by mounting a plurality of planar plate blocks.

As clearly shown in FIG. 2, the square block b for the partition S is stacked perpendicularly to each other in the step adjacent in the vertical direction. For this reason, a gap is formed between the upper and lower stages, and this gap is open in directions orthogonal to each other. Moreover, this gap is a large space h that is slightly shorter than the square bar block b. For this reason, the storage volume in a tank can be enlarged.
In addition, the square block b for the partition S can connect the outer walls W, W to maintain the strength of the tank structure high.

Next, a rectangular bar block constituting the outer wall W and the partition S will be described. The square bar blocks 10 and 20 shown in FIGS. 3 and 4 show two types of long blocks, and the square bar blocks 30 and 40 shown in FIGS. 5 and 6 show two types of short blocks.
The rainwater storage and infiltration facility RP of the present invention can be composed of only the long blocks 10 and 20, or can be composed of only the short blocks 30 and 40, and the long blocks 10 and 20 and the short blocks 30 and 40 are combined. Can also be configured.
When the long blocks 10 and 20 are used, it is easy to construct a storage and penetration facility RP such as rainwater. When the short blocks 30 and 40 are used, it is easy to construct a storage and penetration facility RP such as rainwater small. Combining the long blocks 10 and 20 and the short blocks 30 and 40 makes it easy to construct a storage and infiltration facility RP such as rainwater having a complicated shape.

Further, on both sides of the convex portion 31 and the concave portion 32, engaging concave portions 33, 33 that engage with the other square bar block convex portions 31 are formed as orthogonal engaging portions.
A fitting convex part 34 for fitting with the bottom surface of the upper block is formed on the upper surface, and a fitting concave part 35 for fitting with the top surface of the lower block is formed on the lower surface. The number of the engaging convex portions 34 and the engaging concave portions 35 is eight, but the number is arbitrary.
In addition, one vertical recess 36 is formed on both side surfaces.

Further, one vertical recess 46 is formed on both side surfaces.

(Lid block)
The lid block 50 will be described with reference to FIG.
The lid block 50 is a square having a certain thickness in a plan view. On the lower surface of the lid block, a fitting recess 55 that fits into the fitting protrusions 14 to 44 of the square bar block is formed.
A nut for screwing the lifting bracket is embedded in the upper surface of each square bar block 10-40 including the lid block 50.

(Porous concrete)
The square bar blocks 10, 20, 30, 40 and the lid block 50 are made of porous concrete.
Porous concrete is porous concrete in which many continuous pores are formed. Accordingly, moisture can pass through the square bar blocks 10, 20, 30, 40 and the lid block 50.

(Square bar block assembly structure)
The assembly structure of the square bar block will be described with reference to FIGS.
FIG. 8 shows the arrangement of the rectangular bars on the lower side, and the thick solid line shows the arrangement blocks on the same stage. FIG. 9 shows the arrangement of the square bar block on the upper stage side, and the thick solid line shows the arrangement block in the same stage.
As can be seen by comparing FIG. 8 and FIG. 9, a plurality of square bar blocks 10 and 20 are vertically stacked on the outer wall 1. Therefore, there is no large gap on the outer wall, and no earth or sand enters. In the partition block, the upper side square bar block 10 and the lower side square bar block 10 are arranged orthogonally, and the square bar blocks 10, 10 of the upper and lower adjacent stages are stacked only at both ends. The above-described fitting convex portions 14 to 44 and fitting concave portions 15 to 45 are fitted to each other. Due to such a stacked form, a space substantially corresponding to the volume of one square bar block is provided between the upper and lower square bar blocks 10 and 10. However, both end portions of the square bar block are stacked portions, and these portions do not form gaps, but have a small volume and a sufficiently large space.

Since it is a structure as described above, the block structure of the present embodiment is formed by connecting engagement portions 11 to 41, 12 to 42 and orthogonal engagement portions 13 to 43 formed at both ends of the square bar blocks 10 to 40, respectively. Since the adjacent square bar blocks 10 to 40 are not easily disengaged, the resistance to external force is high, and the function of the storage and permeation tank can be fulfilled for a long time.
Further, as shown in FIGS. 8 and 9, the installation is not limited to a quadrangle, but a polygon whose shape is changed in a plane.
As shown in FIG. 2, as a result of the rectangular bar blocks 10, 10 of the partition being orthogonal to each other in the upper and lower adjacent stages, a space is formed between the upper and lower stages, and a continuous large internal space is formed. For this reason, even if the installation area is the same, a large amount of water can be secured. Furthermore, since the vertical recesses 16 to 46 on the side surfaces of the square bar blocks 10 and 20 used for the outer wall serve as resistance against external forces such as vibration in the ground, the tank structure is not easily broken.

Next, each use form of rainwater storage and infiltration facilities will be described.
