Abstract

The utility model relates to a material for controlling and resisting a flood, in particular to a carried conveniently sand bag that can absorb water quickly to make the volume extend to stop the water flowing. The sand bag for resisting flood comprises a plastic compound bag body, chemical material that is stuffed in the bag and can absorb water with high efficiency, and sediment. The chemical material absorbing water with high efficiency can be the polyvinyl alcohol resins, the polyacrylate sodium, the polyacrylic acid potassium, the polyacrylamide or other mixtures. The sediment can be broken stones, river sands or other mixtures. Compared with traditional sand bags, the sand bag has the advantages of having light weight, convenient transportation and operation, and good effect. The sand bag can be used to stop water flowing to resist a flood urgently, or used to urgently mat low-lyings and ditches covered by a hard board to make the concave places be plane.

Description

Flood fighting sand hill and assembly thereof

Technical field:

The utility model relates to a kind of flood control, flood fighting goods and materials, specifically is a kind of sand hill that water can absorb water fast and make its volume expansion can stop water to flow and be convenient to transport of meeting.

Background technology:

When flood attacks our home, general adopt in the packaging bag that filling is husky, be used for building check dam behind stone or the earth, stop up and break down or piping etc., this is a kind of economy and effective method, but often be subjected to the restriction of natural conditions, and need cost great amount of manpower and material resources and transport resource, even can cause loss without redemption because of losing the best opportune time.

Summary of the invention:

The purpose of this utility model is to overcome the situation that existing disaster relief means fall behind, and the flood fighting sand hill and the sand hill assembly of a kind of in light weight, convenient transportation, effect brilliance is provided.

Flood fighting sand hill described in the utility model comprises high-efficiency water-absorbing chemical material and the precipitum loaded in Polywoven Bag bag and the bag.

High-efficiency water-absorbing chemical material described in the utility model can be polyvinyl alcohol resin, Sodium Polyacrylate, polyacrylic acid potassium, polyacrylamide or its mixture; Described precipitum can be rubble, river sand or its mixture.

The high-efficiency water-absorbing chemical material is a kind of macromolecular compound with light weight cross-linked structure, on the strand own hydrophilic radical is arranged, can absorb self heavy hundred times or more water, after the suction, own wt is hundreds of times increase and generates colloid, in the Polywoven Bag bag of high tenacity, expand at a high speed, form a software chemistry sand hill.Owing to be filled with precipitums such as Shi Sha in the bag simultaneously, can allow sand hill fall in the water, be difficult for being taken away by current.Certainly, the volume of Polywoven Bag should be considered the volume that expands in high-efficiency water-absorbing chemical material suction back.

Flood fighting sand hill assembly described in the utility model is to place the plastics mesh bag to form an assembly in some flood fighting sand hills, so that increase work efficiency and stop up effect.In like manner, the intensity of plastics mesh bag and volume also should be considered tension force and the volume that expands in high-efficiency water-absorbing chemical material suction back.

Because thing when the flood fighting sand hill is the spare time, the goods and materials of using when tight, and content is a kind of material that is easy to moisture absorption, therefore, moistureproof external packing is absolutely necessary, and moistureproof external packing should be easy-tear type, makes flood fighting sand hill assembly before dropping into water, needn't the just peelable damp-prrof packing bag that removes of any instrument; For the ease of storing and transportation, the transportation loading and unloading base anchor is set in the bottom of flood fighting sand hill assembly.

The utility model and traditional sand hill relatively, have in light weight, be convenient to packed and transported, easy to operate, advantage such as result of use is good, mainly as stoping water to flow, the usefulness of a urgent flood fighting; Also can be used for low-lying, the urgent place mat in ditch, pad is gone up hardboard above, and changing low-lying is the usefulness on level land, for example is used for military affairs or engineering.

Description of drawings:

Fig. 1 is the structural representation of embodiment 1 flood fighting sand hill.

Fig. 2 is the structural representation of embodiment 2 flood fighting sand hill assemblies.

The specific embodiment:

Embodiment 1, flood fighting sand hill.

With reference to Fig. 1, this flood fighting sand hill 1 is made of filling high-efficiency water-absorbing chemical material and precipitum 12 in Polywoven Bag bag 11 and the bag.Described high-efficiency water-absorbing chemical material can be chosen polyvinyl alcohol resin, Sodium Polyacrylate, polyacrylic acid potassium, polyacrylamide or its mixture.Precipitum can be chosen river sand, before the pack, needs river sand is dried or flood is done, prevent river sand with the storage period of moisture effects high-efficiency water-absorbing chemical material.The flood fighting sand hill can use separately, also can be packaged into assembly and use.

Embodiment 2, flood fighting sand hill assembly.

With reference to Fig. 2, this flood fighting sand hill assembly, being loaded on plastics mesh bag 2 by some bag embodiment 1 described flood fighting sand hills 1 constitutes, and in the outside of described plastics mesh bag 2, easy-tear type damp-prrof packing bag 3 is set, and its bottom transportation loading and unloading base anchor 4 is set, big vast sand hill assembly is anchored on the transportation loading and unloading base anchor 4 by bale ties 5.
