Abstract

The utility model discloses a water expanding type flood preventing and leakage blocking bag, which is provided with an outer sealing bag (1) and an inner sealing bag (2) which have favorable water permeability, wherein, the cross-section of the outer sealing bag (1) presents a rectangular shape, a trapezoidal shape or a triangle shape; the shape and the size of the inner sealing bag (2) are corresponding to the shape and the size of the outer sealing bag (1); a mixture filling material (3) which is composed of a small amount of fine sandstone sediment and high water absorption resin is arranged in the cavity of the inner sealing bag (2); at least one corner of the corners of the outer sealing bag (1) is provided with a buttonhole (4), and flood preventing and leakage blocking bags are connected with each other by ropes (5) which penetrate through the buttonholes (4). The utility model solves the problems that an existing leakage blocking bag which is subjected to water stream impact displaces or floats and can not be resistant to flood impact, etc. The utility model has the advantages that the structure is simple, flood preventing and leakage blocking effects are favorable, the utility model can not displace subjected to the water stream impact, etc. The utility model is widely suitable for being used in occasions, such as water seepage and landslide of a water reservoir or a river course bank, flood prevention and emergency fight, engineering flow closure, blind ditch blocking, blind hole blocking, flood prevention dam extension, the construction of waterproof enclosing walls, etc.

Description

Water expansion type flood control leak stoppage bag

Technical field the utility model relates to a kind of water expansion type flood control leak stoppage bag, more particularly, relate to the mixture filler be made up of fine aggregate deposit and high hydroscopic resin be housed in a kind of bag, can be used for flood control, reservoir, engineering dam etc. flood control leak stoppage bag.

Background technology in the prior art, existing various flood control leak stoppage bags, the most common usefulness is with the gunnysack leak stopping that sandstone is housed, its volume is big, Heavy Weight, more because of meeting the leak that do not expand behind the water, plugging effect is not good enough; Patent No. ZL00257909.X Expanded closure bag discloses adorns a small amount of super absorbent resin in a kind of, it dams effective, but have following shortcoming: the one, density diminishes behind the super absorbent resin water-swellable, be easy to be subjected to water impact and be subjected to displacement or floating, the 2nd, this class means that bag does not connect each other of damming, all bags that dam are depended merely on overlapping each other use, do not form powerful making a concerted effort, be difficult to stop the impact of violent flood and indestructible, thereby need to improve.

The summary of the invention the purpose of this utility model be to provide a kind of plugging effect of controlling flood good, can not be subjected to water impact and be subjected to displacement or water expansion type flood control leak stoppage bag that floating and anti-flood impacts.

In order to achieve the above object, the utility model provides following technical scheme: design a kind of water expansion type flood control leak stoppage bag, have good the sealing outer bag (1) and seal inner bag (2) of water permeability, seal in the inner bag (2) high hydroscopic resin is housed, it is characterized in that: the cross section that seals outer bag (1) is rectangular, trapezoidal or triangle, seal the shape and size of inner bag (2) and seal outer bag (1) and adapt, seal the mixture filler of being made up of fine aggregate deposit and high hydroscopic resin on a small quantity (3) is housed in the partial cavity of inner bag (2), each angle of sealing outer bag (1) has at least one jiao buttonhole (4) is housed.

The utility model technical scheme preferably is: when the cross section of bag (1) is rectangular outside sealing, have two buttonholes (4) or four buttonholes (4), when having two buttonholes (4), be distributed on cornerwise two angles; The cross section of bag (1) is when triangular in shape outside sealing, have a buttonhole (4) then this buttonhole (4) be positioned on the position at minimum angle; Each is controlled flood and passes buttonhole (4) by rope between the leak stoppage bag and be coupled to each other.Like this, can be according to actual needs, difform leak stoppage bag is used for different positions, is convenient to intercept tight and realizes firm connection between each bag, make stressedly evenly to connect firm and form powerful making a concerted effort, be easy to stop the impact of violent flood and indestructible.

The utility model technical scheme preferably is: the filler (3) of mixture that seals mixture filler (3) in inner bag (2) partial cavity and be any one or a few super absorbent resin of fine aggregate deposit and polyacrylate, starch acrylamide silicate polymer or polyvinyl alcohol.Fine aggregate deposit proportion is heavier, can not expand because of water logging again, and it is mixed use with super absorbent resin, and can not expanding because of super absorbent resin is violent, it is floating or be easy to displacement to reduce after the density; Polyacrylate, starch acrylamide silicate polymer or polyvinyl alcohol super absorbent resin are cheap and easy to get, the leak stopping cost that is used to control flood is low, meet the water that can absorb hundreds of times of himself weight behind the water, not only water absorption is big, and rate of water absorption is fast, and water retaining capacity is also very strong, their suction backs are owing to form the very strong gel of water retaining capacity, can not dewater with simple pressing method, and the fine aggregate deposit is mingled with wherein, plugging effect is good and not frivolous.

Compared with prior art, the utlity model has following tangible advantage: 1, simple in structure, the flood control plugging effect is good, can not be subjected to water impact and be subjected to displacement or floating and cost is lower; 2, of many uses, be suitable for that the dark hole of covered conduit is dammed, stopped up on reservoir, river course embankment infiltration landslide, flood control, engineering, flood control dam is increased and occasion use such as constructing waterproof enclosing wall.
