Description

[Detailed explanation of the invention] This invention is designed to prevent rainwater from falling on the floors of structures such as houses.
When there is a risk of flooding on the ground, the waterproof water bladder of this invention is placed closely between the walls and pillars of houses, etc., and water is injected into the cavity to fill it and stand upright. This invention relates to a waterproof water bag that holds a cube to form a water-blocking wall to prevent water from seeping onto the floor or ground of a building.

Conventionally, such inundation of rainwater has generally been waterproofed by using shielding walls such as soil and weir plates. However, this has the disadvantage that the waterproofing work is complicated and the waterproofing effect is insufficient.

On the other hand, the invention of this application eliminates the drawbacks of these known structures.According to the invention of this application, a narrow flat upper side cloth and an opposing structure arranged at an appropriate interval on the underside thereof are provided. The inner and outer edges of the wide flat lower side cloth are sealed by the rising outer peripheral cloth and the inner peripheral cloth so as to form a rectangular gutter-like cavity with a wide bottom inside. Inside, there is constructed a shielding wall of an appropriate shape such as a substantially straight cylinder shape, which is partitioned at appropriate intervals with a plurality of partitioning fabrics each having a communication port at the bottom to maintain its shape. The shielding wall body is maintained in an upright state by internal water pressure caused by filling the cavity with water from a water inlet provided in the upper cloth, and is sealed with sealing cloths on both sides of the shielding wall body. At the same time, the sealing fabric on both sides is tensioned with a plurality of tension tapes, so if you want to prevent rainwater from seeping in, the waterproof water bag of this application can be placed closely between walls, pillars, etc. Once installed, water is injected into the cavity from the water inlet, and the internal water pressure from the filling of the injected water makes it possible to maintain the upright position.In addition, the inside of the cavity is partitioned with internal partitioning fabric, and water is injected. will be filled with
Since its shape is prevented from collapsing and it is reinforced by the tension tape, it is extremely useful to construct an extremely strong water bladder.

An embodiment of this invention shown in the drawings will be described next.

In the embodiment shown in FIGS. 1 to 7, the inner and outer edges of a narrow flat upper side cloth 1 and a wide flat lower side cloth 2 facing each other at an appropriate interval on the lower side are inclined. The rising outer periphery 3 and the vertically rising inner periphery cloth 4 are sealed to form a rectangular cavity 5 with a wide bottom. A shielding body having an appropriate shape such as a substantially straight cylinder shape is formed, which is partitioned by a plurality of partitioning fabrics 7 provided with communication ports 6 to maintain the shape. The upright state is maintained by the internal water pressure caused by the filling of water 9 into the cavity 5 from the provided water inlet 8, and the openings 10 and 11 at both ends of the shielding wall are appropriately closed with sealing cloths 12 and 13. It is sealed and both sides of the sealing cloth 12,
Reference numeral 13 is tensioned by a plurality of tension tapes 14, 14... as appropriate, and the upper side cloth, lower side cloth, inner and outer peripheral cloths, partition tension cloth, and sealing cloth of the above-mentioned shielding wall are each , made of synthetic fibers such as canvas or strong woven fabrics such as vegetable fibers on which a thermoplastic resin such as vinyl chloride resin is infiltrated and adhered to the surface, and these are suitably bent edges 15, 15, etc. to absorb high frequency waves. The tension tape 14 is bonded by thermal bonding or the like, and the tension tape 14 is made of a strong woven fabric such as canvas, and has a plurality of water holes 16, 16 formed in the partition tension cloth 7.
...fits loosely inside, both ends 17, 18, 17, 18...
is bonded to the sealing cloth by high-frequency thermal bonding or the like, and a drain port 20 that can be opened and closed by an opening/closing cloth 19 is provided on the lower side of the inner peripheral cloth 4, and a drain pipe 25 is connected to the drain port 20. The water 9 in the cavity 5 is discharged through the hole.

Furthermore, connecting cloths 22 such as Velcro fasteners are provided on the upper and lower outer surfaces of the both side sealing cloths 12 and 13, respectively.
22, 23, 23 are fixed thereto, and connecting cloths 26, 2 are provided with a plurality of eyelets 25, 25, .
6 is provided.

A plurality of shielding bodies can be tightly connected by the connecting cloth and the connecting string.

In the drawing, 27 indicates the embolus of the water inlet 8, 28 indicates rainwater, and 29 and 30 indicate pillars and walls.

FIG. 8 shows a sectional view of another embodiment in which a cavity having a truncated pyramidal cross section is formed by inclined inner and outer peripheral cloths 3 and 4, respectively.

In this way, according to the invention of this application, in order to prevent rainwater from seeping in, the waterproof water bag of this application is placed closely between walls, pillars, etc.
By injecting water into the cavity from the water inlet, it is possible to maintain the upright state by the internal water pressure caused by the filling of the water, and the inside of the cavity is partitioned by an internal partitioning cloth and the cavity is filled with water. This prevents the water bag from deforming and is reinforced by the tension tape, making it possible to construct an extremely strong water bag, and to drain the water by opening the drain port after use. It is extremely useful.
