Abstract

The utility model discloses a water expansion bag, be in including outer bag, inner bag and setting water expansion agent in the inner bag, the inner bag with outer bag links together through the rope made of hemp, outer bag is sack or plastic woven sack, the inner bag is chemical fabric bag or nonwoven sack, rope made of hemp surface scribbles the coating that absorbs water, the coating that absorbs water is acrylic acid or N, N - methene bisacrylamide. The utility model provides a water expansion bag, the inner bag links together through the rope made of hemp with outer bag, a bulk strength and anti water impact performance for improving water expansion bag, wherein the rope made of hemp has the effect of drainage, can improve water expansion bag's the speed of absorbing water, and through the coating that absorbs water that coats on the rope made of hemp, can improve the drainage speed of the rope made of hemp, thereby further improve water expansion bag's the speed that absorbs water, make the inflation bag to expand rapidly, it is slow to avoid the water expansion bag speed of absorbing water, receive the problem that water impact takes place the drift easily.

Description

A kind of water uptake expansion bag

Technical field

This utility model relates to flood control field of harnessing the river, and particularly relates to a kind of water uptake expansion bag.

Background technology

China is the country that a flood takes place frequently, abnormal particular with global climate, and local flood is even more serious, when there is flood, dams through carrying out water blockoff frequently with water uptake expansion bag.At present, in order to improve leak stopping capability, through being everlasting, water uptake expansion bag adds High hydrophilous resin, but the absorption speed of this water uptake expansion bag is slow so that it easily, under water impact, drifts about, it is difficult to play the effect that water blockoff dams.

Utility model content

In view of this, the purpose of this utility model is to provide a kind of water uptake expansion bag, solves existing water uptake expansion bag absorption speed slow, it is easy to be subject to water impact and the technical problem of drift occurs.

To achieve these goals, this utility model provides following technical scheme:

A kind of water uptake expansion bag, including outer bag, inner bag and be arranged on the water absoption expanding agent in described inner bag；Described inner bag and described outer bag are linked together by the rope made of hemp；Described outer bag is gunnysack or Polywoven Bag, and described inner bag is chemical fibre cloth bag or non-woven bag；Described rope made of hemp surface scribbles the coating of drafting, and described the coating of drafting is acrylic acid or N,N methylene bis acrylamide.

Preferably, described water absoption expanding agent includes the attapulgite of 60～80%, 5～60% bentonite, 2～20% anhydrous gypsums and 1～15% High hydrophilous resin.

Preferably, described water absoption expanding agent is high-molecular polythene water-absorbing resin.

Preferably, the length-width ratio of described outer bag and described inner bag is 2～4:1.

Preferably, it is provided with filler between described outer bag and described inner bag.

Preferably, described filler is space wadding or acrylic staple fibre.

Can be seen that from technique scheme, the water uptake expansion bag that this utility model provides, inner bag and outer bag are linked together by the rope made of hemp, it is used for improving bulk strength and the anti-current-rush performance of water uptake expansion bag, wherein the rope made of hemp has the effect of drain, the absorption speed of water uptake expansion bag can be improved, and by being coated with the coating of drafting on the rope made of hemp, the drainage speed of the rope made of hemp can be improved, thus improving the rate of water absorption of water uptake expansion bag further, expanding bag can be expanded rapidly, avoid water uptake expansion bag absorption speed slow, it is easily subject to the problem that drift occurs water impact.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the structural representation of this utility model water uptake expansion bag.

In Fig. 1:

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.

As it is shown in figure 1, the water uptake expansion bag that this utility model provides, including outer bag 1, inner bag 2 and be arranged on the water absoption expanding agent 3 in described inner bag 2；Described inner bag 2 and described outer bag 1 are linked together by the rope made of hemp；Described outer bag 1 is gunnysack or Polywoven Bag, and described inner bag 2 is chemical fibre cloth bag or non-woven bag；Described rope made of hemp surface scribbles the coating of drafting, and described the coating of drafting is acrylic acid or N,N methylene bis acrylamide.

In technique scheme, outer bag 1 is gunnysack or Polywoven Bag, arranges, by crisscross, the intensity improving water uptake expansion bag；Inner bag 2 is chemical fibre cloth bag or non-woven bag, is placed with water absoption expanding agent 3 in it, is integrated for 2-in-1 with inner bag, forms imbibition body；Inner bag 2 and outer bag 1 are linked together by the rope made of hemp, it is used for improving bulk strength and the anti-current-rush performance of water uptake expansion bag, wherein the rope made of hemp has the effect of drain, the absorption speed of water uptake expansion bag can be improved, and by being coated with the coating of drafting on the rope made of hemp, it is possible to increase the drainage speed of the rope made of hemp, thus improving the rate of water absorption of water uptake expansion bag further, expanding bag can be expanded rapidly, it is to avoid water uptake expansion bag absorption speed is slow, it is easy to be subject to the problem that drift occurs water impact；Wherein the coating of drafting is acrylic acid or N,N methylene bis acrylamide.

It should be noted that, in order to improve the holding capacity of water uptake expansion bag, strengthen the stable fastness of water uptake expansion bag, avoiding under water impact, produce drift, water absoption expanding agent 3 can be the attapulgite of 60～80%, 5～60% bentonite, 2～20% anhydrous gypsums and 1～15% High hydrophilous resin, it is also possible to high-molecular polythene water-absorbing resin, both water absoption expanding agents 3 can both make the water absoption expanding agent 3 in bag be evenly distributed and closely knit.

It should be noted that when the length-width ratio of outer bag 1 and inner bag 2 is 2～4:1, it is reasonable that water uptake expansion bag arranges comparison, it is possible to effectively resists the impact of current.

It should be noted that for the absorption speed improving water uptake expansion bag further, improve anti-current-rush, be provided with filler 4 between outer bag 1 and inner bag 2, filler 4 can be space wadding or acrylic staple fibre.Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses this utility model.The multiple amendment of these embodiments be will be apparent from for those skilled in the art, and generic principles defined herein when without departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, this utility model is not intended to be limited to the embodiments shown herein, and is to fit to the widest scope consistent with principles disclosed herein and novel features.
