(Configuration of water storage device)
As shown in FIGS. 1 to 3, the water storage device 1 is configured by winding and laminating pipe materials in a spiral shape. The pipe laminate 6 is provided with an outlet 5 at the top and an inlet 4 at the bottom. More specifically, the inflow port 4 is connected to one end of a tube material stacking portion 6 that has been wound and stacked, and the outflow port 5 is connected to the other end of the tube material stacking portion 6. As shown in FIG. 10A, a water pipe 12 drawn from the outside of the house 10 is connected to the inlet 4, and a pipe 11 laid in the house 10 is connected to the outlet 5. It is connected to the.

  The tubular material stacking portion 6 can be constituted by winding one tubular member that stores water therein or a plurality of tubular members connected in a spiral manner and stacking them. In the present embodiment, the tube stacking unit 6 is configured by stacking the stacking units 61 that are spirally wound around the tube as shown in FIG. 4. In each stacking unit 61, the tube is spiral-shaped. The outer end 61a and the inner end 61b wound around are smoothly bent and inclined in the opposite directions. In FIG. 4, (a) and (b) represent the front and back of the same stack unit.

  And the pipe material lamination | stacking part 6 piles up each lamination | stacking unit 61,61 ... so that the front and back may become opposite alternately, and the inner ends 61b and 61b of the lamination | stacking unit located up and down, or outer ends 61a and 61a mutually Are connected at the junction 61c and stacked. The inner ends 61b, 61b or the outer ends 61a, 61a are connected to be inclined up and down, and a constant hydrodynamic gradient is formed at the connecting portion. Thus, the friction loss in the internal water flow can be minimized by connecting the upper and lower pipe members so as to be smoothly bent or smoothly inclined with a free pipe or the like. In addition, as shown in FIG. 2 (b), the connection between the upper and lower pipe members is made up and down as shown in FIG. 2 (b) instead of smoothly bending the end portion of the pipe at the inner edge or the outer edge of each stacked unit. You may make it arrange | position the flexible pipes 61d and 61e which incline the outer ends and inner ends of a pipe material smoothly between the laminated units 61 and 61 located.

  In addition, pipes that have been rolled up and stacked may be fastened together with belts, wires, or other jigs, or fixed by welding, etc., to prevent deformation. When formed, it is desirable to use a laminated container described later.

As shown in FIG. 4B, when the valves 52a and 52b are disengaged, the check valve 52c is pressed against the narrow diameter portion of the constricted shape by the water pressure on the upstream side to stop the water. . According to this, in normal times, when a pair of valves 52a and 52b are connected and water is passed, and a sudden change in water pressure occurs on the downstream side during a disaster, the downstream valve 52a is disconnected, The inflow of sewage from the outside is blocked, and the upstream check valve 52c can prevent the water in the apparatus from being ejected.

  Further, such an emergency stop valve 52 may be provided on the inflow port 4 side. In this case, the emergency water stop valve 52 is provided on the upstream side of the check valve 7 so as to stop the water by fluctuation of the water pressure on the upstream (water pipe 12) side. According to this, when the upstream side of the water pipe 12 is damaged at the time of a disaster and the water pressure fluctuates, the water can be stopped, and the sewage generated on the upstream side is prevented from flowing into the apparatus through the inlet 4.
