Abstract

PROBLEM TO BE SOLVED: To prevent a leakage by fitting a bag body having a float member mounted on the opening edge part, the bag body being formed by setting a flexible water shielding sheet having a cover layer of synthetic resin or the like laminated thereon to an extension length of the total sum of the inside diameter or more followed by thermally fusing and seaming. SOLUTION: To a box-shaped inside wall 5 having an opened upper surface which is surrounded by a water tank 2 made of concrete, a bag body is fitted in the freely isolated state by use of a free fitting part 6. The bag body is formed by thermally fusing and seaming a water shielding sheet 3 set and cut to a protruded extension length of the total sum of the inside diameter of the water tank 2 or more. It is installed to the inside of the upper opening part 7 of the water tank 2 in the state of rolling and covering a float member 4 by turning down the terminal of the sheet 3. Thus, the stored water is held in accommodation to a shape change such as crack, damage, or deformation, and a leakage can be prevented by waterproof mortar at low cost.

嵌装袋体を工業的有利に得ることにある。As described above, when water leakage is prevented by waterproof mortar and a waterproofing agent is applied to the inside of a concrete structure, all of these construction methods can prevent cracking, damage or deformation of the structure. The difficulties have not been solved yet, and they are still in a very fragile repair range, and especially in underground buried water storage tanks, there is a drawback that they are easily affected by the behavior of the surrounding sedimentary layers and groundwater. Therefore, for example, FR inside the water tank
Although the method of forming a double layer by the P method is also adopted, it has a drawback that it is extremely vulnerable to cracking, damage and deformation including disasters such as earthquakes, and that the construction cost is high. The present invention is a bag body composed of a water-blocking sheet on which a resin coating layer of at least a flexible synthetic resin or the like is layered, and the bag body is extended by a total length equal to or larger than the inner diameter length of the water tank to be fitted. It is characterized in that it has a length and is separately fitted with an inner side surface of the water storage tank with a clearance, and that a float member capable of following the liquid level position of the stored water of the bag body is attached. It is an object of the present invention to provide a conformable water storage tank fitting bag. A second object of the present invention is to industrially obtain a water storage tank fitting bag that adapts to the shape of the inside of the water storage tank of underground burial and can follow the change of the liquid level.

き貯水機能を継続できる。In the present invention, the bag made of the water-blocking sheet having a flexible resin coating layer such as a synthetic resin layered thereon has a permissible length not less than the sum of the inner diameters of the water tanks to be fitted. Well,
That is, in order to be able to cope with changes in form such as cracks and deformation of the water storage tank, it is appropriate that the extension length of the total inner diameter length or more is set within the range of 5 to 15% of the total inner diameter length. . As a result, even if the shape of the water tank changes due to cracks, damage, deformation, etc., the flexible water-impervious sheet exhibits conformability to deformation, and cracks, damage, deformation, etc. It is possible to continuously hold the stored water that has been poured into the water storage tank in various forms. Further, various liquid substances and the like that enter from the outside due to cracks in the water storage tank are blocked by the bag body and do not affect the stored water stored in the bag body at all. Further, in the present invention, the bag has a so-called double structure in which the bag is separated and fitted to the inner surface of the water tank with a clearance (free fitting portion) without being bonded or joined to the inner surface of the water tank. The bag body is configured to be a free fitting type without being joined or fixed to the inner wall of the water storage tank. As a result, even if cracks, damages, or deformations occur inside the water tank, their effects are blocked, the bag stores the desired stored water, and conforms to the forms such as cracks and deformations, The water storage function can be continued.

That is, it is necessary to separately deal with the fluctuation of the liquid level of the stored water in the bag, that is, the water level. Therefore, in the present invention, a float member made of a buoyant material selected from, for example, resin foam is attached to the upper opening of the bag. As a result, when the bag body that is separately fitted in the water tank is full of water, the water-blocking sheet of the bag body is in a suspended state due to the buoyancy function of the float member attached to the upper edge of the bag. In addition, the bag body conforms to the shape of the inside of the water storage tank and can maintain a full state. In addition, when the stored water is sucked out and reduced in water, the upper edge of the bag lowers together with the attached float member, but the stored water can be retained in that state, and when the water level increases. The upper end edge of the bag body is raised by the float member, and the full state can be maintained again.

In the case of a water tank installed outdoors, in addition to ultraviolet rays, it is necessary to cope with weather resistance, stains caused by exudation of plasticizer and dust adhesion, etc., and the acrylic resin having weather resistance in the resin material of the bag body, Alternatively, it is preferable that the surface treatment is performed with a fluororesin or the like. Further, as measures against rain and wind, for example, a structure such as a shielding member or a cover lid stopper for preventing rainwater from penetrating across the upper opening of the water tank and the upper edge of the bag body should be adopted. You can Further, in order to maintain the behavior of the float members attached to the upper edge portion of the bag body and the mutual space therebetween, it is also possible to adopt a configuration in which a bridging member is attached in a bridging manner between the opposing float members.

3m x vertical tangential line height of 3m, cylindrical fire protection water tank with a capacity of about 40 tons, each with a protruding extension length of 5%, cut and welded around the bottom and other parts by welder welding Then, they were joined by welder-heat fusion sewing to produce a bag. This was fitted into the cylindrical water tank. In the upper opening 7 of the bag body, a float member 4 made of a foam polystyrene material which is deformable into a curved shape or the like is divided into ten pieces, and the upper edge 8 of the water-blocking sheet 3 is used. It was attached as a rolled-up state. After the water storage tank fitting bag 1 of the present invention thus constructed is fitted inside the fire protection water storage tank 2 of the underground installation type, the stored water 11 is poured until the liquid level position 10 is full, and the flow is completed. The holding member 4 is kept in contact with the inside of the upper opening 7 of the water storage tank 2 at substantially the same height, and the stored water 11
Was able to be stored in a full state. Next, when the stored water 11 is absorbed to reduce the water, the float member 4 follows the lowered liquid surface position 10 and descends, and the water blocking sheet 3 is slackened at the bottom of the water tank 2 or the like. Although the state can be seen, it was confirmed that the stored water 11 can be stored at the water level at the liquid surface position 10 of the float member 4 also in the reduced water state. Although one embodiment of the present invention has been described, the present invention is not limited to the above-described embodiment, and design changes and the like within a scope not departing from the gist of the present invention are included in the present invention.

Since it has the extended length and the float member is attached to the upper edge, even if a change in shape such as cracks, damage, or deformation occurs, it is necessary to adapt to the shape and retain the stored water. You can In addition, the fitting bag of the present invention has a conventional construction method of applying a waterproofing agent or an FRP inside a water tank.
The construction method solves the disadvantage that the structure is cracked, damaged, deformed, etc., improves the prevention of water leakage by waterproof mortar, and has an effect of being able to cope with it at low cost.
