Abstract

The utility model provides an anti-flood sand-bag swelling when touches water, which stuffs high molecule water absorption swelling materials which are stuffed by easy solubleness damp prevention materials in a sealing way or high molecule water absorption swelling materials which are added with solidifying agent into gunny bags or other bag bodies which are made from natural fiber materials. The utility model has the advantage of light weight. Besides, the utility model can rapidly swell after the absorption of water, and the weight of the utility model can increase tens of times. Furthermore, the utility model can also be solidified after the absorption of water. The utility model can be widely used for the construction of low-tension water stop walls and the fast blockage of pipelines of dams, and the utility model can also be used for the sealing blockage of water permeability mines or other rescue engineering which is needed to be sealed, caulked and stopped for water. Owing to light weight, the utility model is convenient for mass transport or the carrying by people, and earth and stones are not needed to be stuffed temporarily so as to lead to large labor saving. Furthermore, the quick reaction capability of the rescue engineering is effectively enhanced.

Description

Quick-acting water-swellable flood control sand hills

The utility model relates to a kind of protecting wall structure that prevent flood, especially a kind of quick-acting water-swellable flood control sand hills.

For these years, people can only load behind the native stone with straw bag, gunnysack or other container facing to flood and other water damage and its build be blocked the water dykes and dams or plug is stifled breaks down, and some hydraulic engineerings or mine are also permeable with sand bag plug leak stopping water, mine.Though this method is effective, is subject to the restriction of natural conditions, and need employ great amount of manpower and material resources and transportation strength, this disaster relief mode is very easily lost the best opportunity and is resulted in greater loss.

The purpose of this utility model provide a kind of in light weight, transportation is easy to carry, meets water imbibition rapidly, own wt also is tens of times of increases, can effectively improve the quick-acting water-swellables flood control sand hills of the quick-reaction capability of disaster relief engineering.

The technical solution of the utility model is: load by the polymer water uptake expansion material of easy molten barrier material encapsulation in the bag that gunnysack or other natural fiber materials are made or add the polymer water uptake expansion material of curing compound.

This sand hill is compared it with traditional sandbag and is had in light weight, imbibition rapidly behind the chance water, own wt also is tens of times increase and forms gel, if add the curing compound of other compositions, solidify after can also making it meet water, can be widely used in and build low pressure and block waterwall, the stifled dike piping of plug fast, also can be used for shutoff permeable shaft or other need sealing, the disaster relief engineering of filleting, sealing.Because this sand hill is in light weight, be convenient to transport in a large number or carry by personnel, need not again the native stone of interim filling, save a large amount of manpowers and resource, can improve the quick-reaction capability of disaster relief engineering effectively.

Elaborate below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Bag 5 of the present utility model is made by the natural fiber cloth of intermediate density and is formed, and can be seamed into other shapes such as square, circular, microscler on request, each bag should be reserved a little survivor of a murder attempt 1, so that filling material, the bag angle also has fixing with link 2, polymer water uptake expansion (curing) agent 4 needs to be packaged into bar shaped or square with special easy to be molten barrier material 3, and expansion agent should and be filled in the bag by a certain percentage by the bag volume and get final product.

Claims

1, a kind of quick-acting water-swellable flood control sand hill, comprise the bag of making by gunnysack or other natural fiber materials, it is characterized in that: polymer water uptake expansion material of loading in the bag (5) (4) that is encapsulated by easy molten barrier material (3) or the polymer water uptake expansion material that adds curing compound.
