Description of the Related Art In an urbanized area where there are few unpaved roads and vacant spaces, rainwater flows into rivers through gutters without penetrating into the ground, and large amounts of rainwater concentrate on rivers during the rainy season. In short, it exceeds the capacity of rivers, causing so-called urban floods. On the other hand, in the dry season, the water level of dams and lakes decreases, resulting in water shortages.

It has become.

There is known a structure having a structure in which sheets are stacked and filled, and a water-permeable sheet is stacked thereon and covered with soil. Further, as a water-permeable groundwater tank, there is known a water-permeable groundwater tank having a structure in which a water-permeable sheet is provided along the side surface, and similarly, a filling body is filled inside the water tank and the upper part is covered with a water-permeable sheet and soil. ing.

破壊され易くなるという問題があった。However, as described above, the synthetic resin fillers provided with the pillars are arranged vertically and horizontally and stacked up and down to fill the underground water tank, and the outer periphery of the synthetic resin side plate is provided. Although the filling structure provided with is said to improve the pressure resistance against the earth pressure from the surroundings somewhat due to the side plate, the side plate alone is not sufficient in pressure resistance, so the side plate is destroyed by the earth pressure from the surroundings, and the soil becomes groundwater. I was worried about getting inside the tank and being crushed. In particular, when stacking fillers having long pillars, there is a problem that the side plates are easily broken by the earth pressure because the vertical interval of the frame of the filler supporting the side plate from the inside is widened.

ことになる。To increase the strength of the side plate, the thickness of the side plate may be increased or reinforcing ribs may be formed on the side plate. However, even if the strength of the side plate is increased by such a method, there is a limit. Not only does the cost increase due to use, but the weight of the side plate increases, making it difficult to carry, resulting in a decrease in workability.

A long round pipe made of a hard-to-bend metal or hard synthetic resin is stretched over, and both ends of the round pipe 5

That is, since four rod receiving portions 5b are formed on the side plate 5 as described above, two projecting rods 9 are bridged between the left and right side plates 5, 5, and both ends thereof are formed on the upper side. By fitting the two rods 9 between the front and rear side plates while fitting them into the two rod receivers 5b, 5b, and fitting both ends into the lower two rod receivers 5b, 5b, The two rods 9 in the left-right direction and the two rods 9 in the front-rear direction are mounted so as to be displaced up and down so as not to hit each other.

柱４２に側方から当たって座屈させる恐れは生じない。Since the rod receiving portion 5b of the side plate 5 is formed in an annular shape, a round pipe is used as the strut 9; however, the strut 9 is not limited to such a round pipe. Instead, hollow or solid rods having various cross-sectional shapes can be used. In particular, cross-sectional shapes that are hardly bent in the left-right direction than in the up-down direction (for example, oblong oval, rectangular, H-shaped, etc.) A bar having a sectional shape is preferably used. When the bar 9 having such a cross-sectional shape is bridged between the opposing side plates 5, 5 when the earth pressure acts on the side plates 5, the bar 9 may bend vertically. Does not bend in the left-right direction, so that there is no possibility that the strut 9 will hit the pillar 42 of the filler 4 from the side and buckle.

May be changed to FIG. 6 is a front view showing another example of the side plate in which the number and shape of the rod receiving portions are changed in such a manner, and FIG. 7 is a partial perspective view showing a state in which a stick bar is attached to the side plate.

Therefore, the end of the strut 9 can be fitted into the rod receiving portion 50b very easily from the open upper part.

The two rod receiving portions 50b of the second stage of the side plate 50 are fitted to the two rod receiving portions 50b of the second stage and the third stage. Two rod receiving part 50b
By inserting the rods in the right and left directions, the position of the rod 9 in the left-right direction and the rod 9 in the front-rear direction can be shifted up and down so that the four rods 9 can be bridged, so that the number of the rods 9 is increased. The pressure resistance can be further improved by that much.

Therefore, it can withstand the earth pressure sufficiently. Therefore,
There is almost no fear that the side plate 5 (50) will be broken and the surrounding earth and sand will enter the underground water tank 1.

It is no longer necessary to use a long strut as in the case of bridging a strut between them, and a short strut 9 equal to the interval between the intermediate plate 11 and the side plate 50 can be used. Such a short strut 9 is harder to bend than a long strut when an earth pressure acts on the side wall 50, so that the pressure resistance can be sufficiently improved.

The side plate 50 is prevented from falling off in the event of an earthquake, or a holding rod (not shown) is attached to the outside of the side plate 50 to fix the holding rod to the intermediate plate 11. It is also possible to prevent the side plate 50 from dropping and to prevent infiltration of earth and sand into the underground water tank by fixing with a fastener or the like to the end of the strut 9 bridged between the and the side plate 50.

Although the filler 4 in which the pillars 42 are fitted into the fitting holes 41a of the frame 41 is used, the number of pillars 42 may be increased or decreased,
A filler in which the frame 41 and the pillar 42 are integrally formed of a synthetic resin may be used. As a preferable example of such a filling body, four pillars are integrally formed at four corners on one side of the frame, and a deep hole is formed at a tip of each pillar, and reinforcing ribs are formed on one side of the frame. Can be mentioned.

By inserting the upper half of the core into the hole at the tip of the pillar, the pillars are stacked and filled with the pillars joined up and down.

きる。When the fillers are stacked in a state where the pillars are joined as described above, the interval between the frames of the upper and lower fillers is widened to twice the length of the pillars, and the side plate 5 is caused by the earth pressure. If the side plate 5 is supported from the inside by the strut 9 using the filling structure of the present invention, the side plate 5 can be effectively prevented from being broken, and the pressure resistance can be significantly improved.

防止できるので極めて有効である。In the case where the fillers are stacked in a state where the pillars are joined together as described above, there is a possibility that buckling may occur relatively easily when an external force acts on the pillars from the lateral direction. It is very effective to use a strut having a cross-sectional shape that is hardly bent in the left-right direction as described above, since this buckling can be reliably prevented.

果を併せて奏する。As is apparent from the above description, the filling structure of the underground water tank of the present invention can be supported from the inside by the strut rod even if a large earth pressure acts on the side plate from around the underground water tank. Therefore, it is possible to sufficiently withstand the earth pressure, and it has a remarkable effect that the side plate is broken and the surrounding earth and sand can be prevented from entering the underground water tank. And the end of the stay rod is fixed to the side plate, or the holding rod attached to the outside of the side plate is fixed to the end of the stay rod, which can prevent the side plate from falling off in the event of an earthquake, It also has the effect of preventing intrusion.
