It has been.
However, in the above structure, the constituent parts of the unit member are connected in a substantially series in the vertical direction, so that the strength can be increased. However, a gap is formed in the lateral direction (side), and the constituent parts of the unit member are There is a drawback that strength is weakened because it is not laid horizontally.
In particular, since the structure is covered with a waterproof sheet or a protective sheet and is embedded in the ground or underground, it is difficult to reinforce when the strength is insufficient.
In addition, there is a drawback in that the lateral strength is not sufficient due to the large porosity even in a configuration in which a large gap does not occur, such as a configuration in which unit members bent in a channel shape are stacked vertically and horizontally. .

DETAILED DESCRIPTION OF THE INVENTION
Below, the suitable example at the time of applying the buried structure of this invention to groundwater tank 1 is described, referring to drawings.
The unit member 2 of the present embodiment uses a “shinshin block” (trade name: Hayashi Bussan Co., Ltd.) as a well-known container-like member, as shown in a plan view and a bottom view in FIG. 4 and a side view in FIG. Yes.
[0007]
The unit member 2 has a substantially truncated quadrangular pyramid shape having an opening on the top surface and gradually narrowing toward the bottom surface, and a hollow, truncated cone-shaped column portion 25 that opens on the bottom surface side is formed in the center. Has been.
Then, an upper connecting portion 23 made of a hooking hole is formed at the corner of the upper flange 21, and a recessed portion 26 that is recessed inward is formed at the four corners, and the upper surface of the recessed portion 26 A lower connecting hole 24 is formed at a slightly higher position than the bottom surface 22.
[0008]
When the unit members 2 are stacked in the upper stage, the unit members 2 are arranged symmetrically in the vertical direction, aligned with the upper flange 21 and aligned with the upper flange 21 turned downward, and aligned with the bottom surface 22 with the bottom surface 22. Are stacked (see FIG. 11).
The unit member 2 may be a joint having various structures, such as a member having a retaining shaft that engages with the retaining hole, or a tubular member that is fitted to or externally fitted to the column portion 25. A large number of unit members 2 can be connected in the front-rear and left-right directions and in the up-down direction.
[0009]
Here, the reinforcing portion 3 of the present embodiment has a configuration that also serves as a joint function.
That is, as shown in FIG. 1, when the unit member 2 is adjacent vertically and horizontally, the reinforcing portion 3 is hooked into the lower connection holes 24 of each of the upper unit 4 and the lower unit 4 in total of the eight unit members 2. In order to be able to be stopped, a unit member connecting portion 5 in which a pair of upper and lower engaging shafts 51 are arranged at four positions is provided in the center.
[0010]
And the cylindrical latching shaft 51 and the latching wall part 52 of the cross-sectional angle shape which covers the outer side of this latching shaft 51 are formed in the four corners of the said connection part 5. As shown in FIG.
The retaining wall portion 52 is positioned on one of the recesses 26 at the four corners on the bottom surface 22 of the unit member 2, so that the retaining shaft 51 can be latched in the lower connecting hole 24.
[0011]
In addition, four extending portions 6 are formed at intervals of 90 degrees from between the opposing latching shafts 51 of the connecting portion 5.
A connecting component connecting component 4 formed in a hook shape is provided at the tip of the extending portion 6 in order to hook another reinforcing portion 3 adjacent in the extending direction of each extending portion 6.
[0012]
As shown in FIGS. 2, 3, and 6, a pair of locking projections 41 are formed at the distal end of the coupling component 4, while facing the base end of the coupling component 4. A receiving portion 42 for engaging the locking projection 41 of the connecting component 4 is formed.
As clearly shown in FIGS. 2 and 3, the receiving portion 42 has a configuration in which concave and convex portions 43 are formed in the upper and lower portions, and a latching piece portion 44 extends laterally in the center.
[0013]
Therefore, in use, as shown in FIG. 5, the extension portion 6 and the connecting component 4 are arranged in the gap between the unit members 2 so that the connecting components 4 can be latched with each other. .
The reinforcing part 3 ′ is attached to the unit member 2 arranged at the outer end of the embedded structure 1.
[0014]
Accordingly, the reinforcing portion 3 ′ has a configuration in which one or two extending portions and the connecting constituent portions are omitted so as not to protrude outward from the unit member 2 disposed at the outer end, and its width Is set to be the same as the others in the illustrated example, but is preferably set to about half the width so as to be aligned with the end of the unit member 2.
In this way, the reinforcing portion 3 is integrally bridged to the side of the embedded structure 1 so as to intersect vertically and horizontally so as to close the gap between the unit members 2.
Thereby, the intensity | strength of the side of the embedded structure 1 can be raised.
[0015]
In the above embodiment, a large number of reinforcing portions 3 can be connected to form an integrated reinforcing portion group that crosses the embedded structure 1.
[0016]
The reinforcing part 3 of the application example shown in FIG. 7 and FIG. 8 has a structure that also serves as a joint. The base part 31 is formed in a substantially cross shape and is disposed at the four corners that are recessed so as to protrude in a pair of upper and lower sides. It comprises a cylindrical latching shaft 51 and a latching wall portion 52 having an angular cross section whose end is connected to the base portion 31 so as to cover the outside of the latching shaft 51.
[0017]
The retaining wall portion 52 is positioned on one of the recesses 26 at the four corners on the bottom surface 22 of the unit member 2, and the retaining shaft 51 is latched on the lower connecting hole 24.
Thereby, since the reinforcement part 3 and the unit member 2 are united and spanned in the horizontal direction of the embedded structure 1 and serve as a crosspiece, the horizontal strength of the embedded structure 1 can be increased. it can.
[0018]
Further, the reinforcing portion 3 ′ shown in FIG. 9 is attached to the unit member 2 disposed at the outer end of the embedded structure 1.
The reinforcing portion 3 ′ is used together with the reinforcing portion 3 shown in FIG. 7 and has a shape in which the reinforcing portion 3 is halved, so that the outer end portion protrudes outward from the unit member 2. The outer periphery can be formed in a series without covering only the reinforcing portion 3 when the unit member 2 is covered with a waterproof sheet or a protective sheet.
[0019]
Moreover, since tip wall part 32 'has a fixed width | variety, when it collides with the ground, the load added to reinforcement part 3' can be disperse | distributed.
At this time, the distal end wall portion 32 ′ may be set widely as indicated by the phantom line in FIG.
Examples of attaching the reinforcing portion 3 are illustrated in FIGS. 10 and 11.
In FIG. 11, reference numeral 9 denotes a sealing member such as a polystyrene foam or a synthetic resin plate, which is fitted into the outer end of the unit member 2 without a gap to enhance the sealing performance.
[0020]
FIG. 12 illustrates the case of the unit member 2 ′ having a different shape.
The reinforcing portion 3 of this embodiment is composed of a plurality of columnar members that are connected together.
This connection structure is not particularly limited, and even if the columnar members are connected by a joint, or the structure in which the tip of the cylinder part is gradually narrowed to a small diameter and pushed into the other multi-end cylinder part opening and tightened, or a rod A known configuration can be used as appropriate, such as a configuration in which a screw is provided at the front end of the screw and a screw hole is provided at the rear end to connect the screws.
[0021]
And the wide support board 7 is attached to the both ends after a connection so that a load can be disperse | distributed.
In the above embodiment, the unit member 2 ′ forms a gap penetrating in the lateral direction, so that the reinforcing portion 3 is inserted into the gap and horizontally placed in the embedded structure 1 to function as a horizontal rail.
At that time, the reinforcing portion 3 may be provided with connection or restriction means so as to be connected or restricted to the unit member 2, or may be simply inserted and no restriction means may be provided.
In the present embodiment, the diameter is set so as to be restrained by the upper and lower contacts with the unit member 2 ′.
[0022]
In the above embodiment, the structure in which the reinforcing portion 3 is inserted into the gap inside the unit member 2 is illustrated. However, when the gap formed between the unit members 2 and 2 communicates in the lateral direction, the gap is formed. A structure in which a columnar reinforcing portion is inserted into the cylinder may be inserted (see the schematic diagram of FIG. 13).
[0023]
In addition, the configuration of the unit member is not particularly limited, and may be any as long as it has a high porosity such as a hollow member. In short, various design changes can be made without changing the gist of the present invention.
[0024]
【The invention's effect】
Since the present invention uses a reinforcing member to enhance the lateral strength when assembling a buried structure with a high porosity using unit members, the stability and reliability of the structure buried underground or underground Can be increased.
Further, even a unit member that could not be used due to a problem in strength can be used by using the reinforcing portion, so that an embedded structure with a higher porosity can be made.
