Abstract
The utility model relates to a water-absorbing expansion bag which comprises water-permeable outer bag and a water-absorbing expansion body arranged in the outer bag, wherein the water-absorbing expansion body is connected with the outer bag through a connecting belt; the water-absorbing expansion body comprises a plurality of water-absorbing expansion agent carrier layers; each water-absorbing expansion agent carrier layer is internally provided with water-absorbing expansion agent powder; and a layer of non-woven fabric is arranged on each of the upper and the lower sides of each water-absorbing expansion agent carrier layer. The expansion bag has the advantages that the expansion bag has low cost, is convenient in storage and transportation, and can be expanded rapidly after absorbing water; the water-absorbing expansion agent does not lump; and the expansion bag increases rapidly in weight, does not need to depend on sandy soil, and can be used for rapid rescue. After the dangerous case, the expansion bag gradually shrinks due to water loss, and is reusable after being dried.
Description
Technical field:
The utility model relates to the emergency flood fighting technical field, the water uptake expansion bag of using during particularly a kind of emergency flood fighting.
Background technology:
China is the country of a flood pilosity, when flood takes place, be generally used for waterproof, water blockoff most convenient, effectively equipment is exactly a sand hill.But could use because sand hill need pass through the filling sandy soil, and sandy soil are very heavy, need many people constantly load sandy soil, transportation sand hill, waste time and energy, be unfavorable for speedily carrying out rescue work fast.In recent years, the water uptake expansion bag that is used to speedily carry out rescue work occurred, outer bag and inner bag composition are equipped with high hydroscopic resin as water absoption expanding agent in the inner bag, but the water of hundreds of times of himself weight of high hydroscopic resin and fast Absorption after water contacts is used for speedily carrying out rescue work fast.But very easily lump because high hydroscopic resin drops in the water fast,, thereby in flood-fighting, do not obtain real applying so far in case caking promptly reduces its water absorbent rate greatly.
The utility model content:
The purpose of this utility model provides the water uptake expansion bag that a kind of emergency repair is used, can when flood situation take place, and water-control is speedily carried out rescue work with prestissimo, carries out effective waterproof water blockoff at once.The technical scheme of taking for the realization the purpose of this utility model is as follows:
A kind of water uptake expansion bag comprises permeable outer bag and the imbibition body that is contained in the outer bag, links together by connecting band between described imbibition body and the described outer bag; Described imbibition body comprises multi-layer absorbent expansion agent carrier layer, and the water absoption expanding agent powder is housed in the water absoption expanding agent carrier layer, and the both sides up and down of every layer of water absoption expanding agent carrier layer are provided with layer of non-woven fabric.
The utlity model has following advantage: cost is low, deposit, convenient transportation, and suction back rapid expanding, water absoption expanding agent does not lump, and weight increases fast, need not rely on sandy soil, can speedily carry out rescue work fast.After the dangerous situation, expanding bag is because dehydration meeting atrophy gradually is reusable after drying.
Description of drawings:
Fig. 1 is the cross-sectional view of water uptake expansion bag of the present utility model
Among the figure, the 1st, outer bag, 2 are the imbibition body, and 3 is the water absoption expanding agent carrier layer, and 4 is nonwoven, and 5 is connecting band.
The specific embodiment:
Referring to Fig. 1, water uptake expansion bag of the present utility model comprises permeable outer bag 1 and the imbibition body 2 that is contained in the outer bag, links together by connecting band 5 between described imbibition body 2 and the described outer bag 1; Described imbibition body 2 comprises 5 layers of water absoption expanding agent carrier layer 3, and the water absoption expanding agent powder is housed in water absoption expanding agent carrier layer 3, and the both sides up and down of every layer of water absoption expanding agent carrier layer 3 are provided with layer of non-woven fabric 4.
Described water absoption expanding agent carrier layer 3 adopts space wadding or acrylic staple fibre, and it is 70-150 purpose high hydroscopic resin powder that water absoption expanding agent adopts granularity.After in water absoption expanding agent carrier layer 3, adding the super absorbent resin powder,, be equipped with layer of non-woven fabric 4 in the both sides up and down of every layer of water absoption expanding agent carrier layer 3 with its compacting.Be connected with bonding agent between water absoption expanding agent carrier layer 3 and the nonwoven 4, and each layer water absoption expanding agent carrier layer 3 is integrated, form imbibition body 2.
Water uptake expansion bag of the present utility model is with before water contacts, and in light weight, volume is little, is convenient to deposit and transport; In case dangerous situation occurs, it is dropped in the water, because water absoption expanding agent evenly distributes and can not lump, can absorb moisture rapidly fully in expansion agent carrier layer 3, expand rapidly, realize speedily carrying out rescue work fast.
For the ease of preserving, prevent the moisture absorption, outside bag 1 outer setting one deck waterproof plastic bag.During use, expanding bag is transported to the building site of speedily carrying out rescue work, tears outermost waterproof plastic bag off, block is built the place of speedily carrying out rescue work and is got final product.Washed away for preventing, can be around the expanding bag or the centre squeeze into timber and fix.
