Abstract

Provided is a sandbag capable of quickly laying with less labor in the occasion of a disaster to cope with the restoring work after a disaster. A water absorbing material 4 increasing the volume when it contains water and an inner bag 3 are contained in an external bag 2. After water is supplied in the water absorbing material 4 to expand the external bag 2 to use the bag as a sandbag, the inner bag 3 is taken out from the external bag 2, the inner bag 3 can be used again as a sandbag 1. The expansion of damage can be quickly depressed by expanding the external bag 2 by the water absorbing material 4 in the occurrence of a disaster. Further, when a restoration work is carried out after elapse of time from the occurrence of the disaster, it is not necessary that a new sandbag is prepared because the inner bag 3 can be used.

Description

Sandbag

[technical field]

The present invention relates generally to employed sandbag when floods take place.

[background technology]

Owing to the floods that river inundation or heavy rain etc. causes ground surface to soak, attacking more autumn with plum rain season or typhoon is the center, and will inevitably take place every year.Wait when causing big flood cross flow ground surface because the river inrushes, stacking sandbag around it is to prevent one of measure that building soaks.Sandbag is to be sewn into sack with burlap etc., and an end ties with rope as the money girdle, the inside soil of packing into, and a plurality of wall shapes of building into are in order to stop flowing water.

Sandbag only just be can use when floods take place, so usage frequency is very low, but river administrative staff etc. take the unit of flood control measure, often will take care of some.When keeping, the soil of surely not packing in bag is piled up but be pressed into flat shape, is placed on narrow and small place and takes care of in a large number.When disaster takes place when, plane sandbag is transported to the scene, the pack of fetching earth from mound or farmland on every side then is laid on required place.

Give the operation of husky packeted soil, carry out at the scene in principle, but taking place not necessarily just to guarantee enough manpowers and soil under this extreme case of disaster.Therefore,, it is expanded,, reached the stage of practicability at present to replace the sandbag product of dress soil at the absorbent materials of packing in advance and can absorb moisture and expand in sandbag inside such as high molecular polymer.But the sandbag of use absorbent material because prolongation moisture in time can be escaped from absorbent material, in the repair of formally carrying out, also still needs to adorn again the sandbag of soil.

Use is packed into behind the sandbag of absorbent material, when needing to adorn the sandbag of soil again in repair, must prepare sandbag separately.But, in the scale of the unpredictable disaster of the moment that disaster takes place, all use up the sandbag of being prepared sometimes after, can't ship new sandbag immediately.In this case, just be difficult to carry out repair, certainly will prolong the time of removing disaster.

[summary of the invention]

The present invention considers at present such present situation and develops, and purpose provides when disaster takes place with seldom labour and can lay rapidly, and can adapt to the sandbag that repair needs after the disaster take place.

Solve the invention that the claim 1 of above-mentioned problem is put down in writing, pack into and absorb the absorbent material and the inner bag that can increase volume behind the moisture in Dai inside outside, expand by bag outside above-mentioned absorbent material water supply makes, after the sandbag use, from outer bag, take out inner bag, inner bag can be used as sandbag once more, sandbag with this characteristics, when disaster takes place, can use rapidly, can also be used in simultaneously in the repair that takes place after the disaster, easily.

Sandbag of the present invention, only different with the past by the sandbag that a sack constitutes, combine by outer bag and two sacks of inner bag.Inner bag has same structure with in the past sandbag, and just as the money girdle is put on rope around peristome, pack into after the soil in inside, sealing rope and can seal peristome once drawing, and makes inside airtight.It is inner that this inner bag is contained in outer bag during fabrication, generally just can't see at all.And outer bag is the sack made from burlap etc., be pressed into during keeping rectangular tabular, can the bulk deposition keeping, the stage of bag is with regard to packed into inner bag and absorbent material making outside.

Absorbent material use to be made employed high molecular polymers such as paper nappy, is characterized in absorbing large quantity of moisture and is not easy to make its escape, and own vol can increase several times.In the process of this absorbent material bag outside making just and inner bag put into inside together, in this stage, it is non-bloating tabular that absorbent material is.Therefore, the sandbag of the present invention that constitutes by outer bag, inner bag and absorbent material, the same with the sandbag in past can the bulk deposition keeping.And absorbent material is contained in the inside of outer bag, rather than is contained in the inside of inner bag, and they are fitted together respectively.

Outer bag is the same with sandbag in the past, is a satchel, but owing to outer bag expands because of absorbent material, inside there is no need the soil of packing into, so do not need to have the peristome as the money girdle, outer bag will be sewed it up all around with line, make the absorbent material of expansion be unlikely to come off.When disaster takes place when, sandbag of the present invention is transported to after the scene, outer bag is dipped in the water, make it be impregnated into inside, absorbent material expands and is deformed into the three-dimensional shape of pillow shape, can stop the water that gushes.For sandbag is interconnected, loaded onto fixedly rope outside around the bag.

Disaster takes place through behind the certain hour, because the water of ground surface reduces gradually, sandbag has been finished its bearing of task and has been removed.In case be difficult to after the absorbent material imbibition utilize once more, so will cut near the part of outer bag end face, take out absorbent material with scissors, it is contacted with dehydrating material based on marble, after the volume minimizing, can be used as combustible and give burning disposal.Simultaneously, the material manufacturing of toxic gas does not take place after will using burning such as natural rubber in the non-slipping block of outer bag etc. yet, so that make outer bag of burning disposal equally.At this moment inner bag uses as yet, and portion's soil etc. of packing into is within it sealed with rope and mouthful can be used as sandbag immediately.

The inner bag that takes out from outer bag can use separately, but does not dispose outer bag immediately sometimes, and wishes to be used effectively.For this reason, the invention of putting down in writing as claim 2 was pointed out, at least a portion around beyond the peristome of inner bag was made integratedly with suture and outer bag, and outer bag is linked up with inner bag, can continue to use outer bag.As previously mentioned, outer bag by suture will around seam get up, do not have peristome, and in the table that constitutes outer bag between two clothes with the peripheral overlapping embedding of inner bag, inner bag is clipped between outer bag the cloth, both are sewed together.

Make with outer bag around the inner bag, after cutting around the outer bag, for native to the inner dress of inner bag, the peristome of inner bag will not sew.Simultaneously, the position of cutting outer bag will stamp shear line in advance in this position than the peristome of inner bag slightly in the outer part, bag outside shear line is cut off takes out after the absorbent material, inwardly packeted soil, seal with rope, like this, just made the sandbag that constitutes by outer bag and inner bag.

Sandbag is because use soaking under the state of water, and the surface of outer bag becomes very sliding easily, therefore can reckon with and ground surface between or and adjacent soil between can not form enough frictional force, be difficult to withstand current, during carrying too cunning also be a problem.For this reason, the invention of putting down in writing as claim 3 was pointed out, Dai surface was provided with non-slipping block outside, makes it have enough frictional force.The form of non-slipping block does not have certain restriction, and the simplest is to be interrupted the material that rubber etc. is easy to generate frictional force is set.This non-slipping block is outer bag apparent one big characteristics, consider factor decision its configuration and sizes such as attractive in appearance.

[specific embodiment]

Fig. 1 has represented the formation of sandbag 1 of the present invention, and Fig. 1 (a) is an oblique view, and Fig. 1 (b) is the A-A end view drawing.Outer bag 2 is to make pouch after burlap is cut off, and is illustrated plane when keeping and transportation, long 60cm, and about wide 40cm, inside packed into inner bag 3 and absorbent material 4.Inner bag 3 is littler than outer bag 2, packs into flat shape, and absorbent material 4 is that certain thickness cuboid is arranged, long 20cm, and wide 10cm, about thick 5mm, area is more much smaller than outer bag.

Absorbent material 4 is by employed high molecular polymer manufacturings such as paper nappys, be aforesaid tabular before using, but when Once you begin absorbing moisture, with regard to rapid expansion, makes outer bag 2 and is out of shape and become the pillow shape.When disaster takes place, expand, at the scene outer bag 2 is soaked in the water, make inner saturated with water in order to make absorbent material.At this moment around suture 5 will sow, do not break halfway, give a tongue-lashing out from outer bag 2 to prevent absorbent material 4.

Sandbag 1 common a plurality of accumulations get up to use, and in order to keep its stacking states, the fixedly rope 6 that connects adjacent sandbag 1 will be connected on the outer bag 2.4 holes about diameter 5mm have been stayed on bag 2 summits next door outside, and fixedly rope 6 passes these holes, do not add at its two ends to fix and can freely use.Therefore, when laying sandbag 1, can be held together, withstand current with adjacent sandbag or with stake etc.

Actual when using sandbag 1, all the things all are immersed in the water, make the surface very sliding, thus outside the surface configuration of bag 2 non-slipping block 8.Non-slipping block 8 shown in Figure 1, be with the cylindrical natural rubber of diameter 10mm, high 3mm with the configuration continuously of the interval two dimension of 15mm, during manufacturing the natural rubber of fusion is sticked to the surface of outer bag 2, staggered chimeric with the fiber of outer bag 2, can not peel off.

Absorbent material 4 just can't utilize after in a single day expanding once more, so absorbent material 4 must waste treatment after use with outer bag 2.But, intractable under the state of bag 2 bulging outside, simultaneously inner bag 3 also uses, and absorbent material 4 and inner bag 3 must be taken out.For this reason, the end face of bag 2 next door has stamped shear line 7 outside, and the bag 2 outside this shear line 7 is cut off with scissors or knife therefrom takes out absorbent material 4 and inner bag 3.Shear line 7 will be imprinted on than suture 5 place slightly in the inner part, so that outer bag 2 is opened easily, also can not scratch inner bag 3 simultaneously.By outer bag 2 absorbent materials that take out 4, contact with dehydrating material remove moisture and reduce volume after, can carry out burning disposal, outer simultaneously bag 2 non-slipping block 8 because of adhered to natural rubber on burlap also can carry out same processing.And the inner bag 3 that takes out, portion loads onto soil within it, just can use as general sandbag immediately.

Fig. 2 has represented to sew on suture 5 formation of the sandbag of making 1 of inner bag 3 all around, and Fig. 2 (a) is an oblique view, and Fig. 2 (b) is the B-B end view drawing.The form of outer bag 2 and absorbent material 4 grades is the same with Fig. 1, but inner bag 3 stitches extremely and fixed with suture 5 around except that peristome, and inner bag 3 can not take out from outer bag 2.But when taking out absorbent material 4 after expansion, considering will be toward dress soil in the inner bag 3, so on the next door of peristome 9, do not sew on outer bag 2.

Fig. 3 represents the use form of inner bag 3, the situation of the sandbag 1 of Fig. 3 (a) presentation graphs 1, the situation of the sandbag 1 of Fig. 3 (b) presentation graphs 2.When the sandbag 1 of Fig. 1 is cut off along outer bag 2 shear lines that printed 7, can shown in Fig. 3 (a), inner bag 3 be taken out with absorbent material 4, the soil of in the inner bag 3 that takes out, packing into, one draws and sealed rope at 10 o'clock, and peristome 9 just can be sealed, thereby has made sandbag.

In addition, when the sandbag 1 of Fig. 2 is cut off along outer bag 2 shear lines that printed 7, can take out absorbent material 4, but inner bag 3 is got to be come out because of being sewn on outer bag 2 with suture., shown in Fig. 3 (b), the peristome 9 of inner bag 3 is being opened, and from here can be to the inside of inner bag 3 soil of packing into, one draws and seals rope then, and peristome 9 just can be sealed, thereby has made sandbag.

The effect of invention

Shown in the invention of claim 1 record, the arrangement of the inside of outer bag packed into absorbent material and Inner bag, absorbent material expands outer bag when disaster takes place, and just can at short notice with less labour To use, can control rapidly the expansion of the condition of a disaster, behind disaster course of emergency certain hour, carry out simultaneously During repair, do not need to allot new sandbag by using inner bag, process rapidly.

Shown in the invention of claim 2 record, outer bag has been sewn on inner bag, use inner bag The time also have outer bag, can increase sandbag intensity and prevent breakage, simultaneously because the surface of outer bag is provided with anti-Slide block has also increased frictional force. Shown in the invention of claim 3 record, be provided with non-slipping block on the surface of outer bag, even be in all around Soaking state, sandbag can not sent out cunning yet, can improve reliability.
