Detailed description of the invention
Fig. 1 is the decomposition diagram of sealing bar in the utility model embodiment;
Fig. 2 is the structural schematic diagram of self-expanding water blockoff bag in the utility model embodiment.
Specific embodiment
In order to preferably explain the present invention, a specific embodiment of the invention is made into detailed elaboration below with reference to legend.
Referring to attached drawing, the technical solution of the utility model is further illustrated.
A kind of cavity or hole in dykes and dams or dam deepwater environment gush leak read fastly closure self-expansion type it is stifled
Water bag divides including bag body, the bi-component self-expanding material being contained in bag body, and by bi-component self-expanding material sealing
The rapid seal being interposed between in two separate chambers of bag body.
As shown in Figure 1, rapid seal is sealing bar 2 comprising the outer bar portion 21 and interior bar portion 22 of longitudinal.Outer bar portion
21 have uniform C-shaped cross-section and both ends open along its length, and the interior bar portion 22 is suitable for being inserted into the outer bar from both ends
The inner space being made of C-shaped cross-section in portion 21.
Preferably, the interior bar portion 22 includes and the inner wall shape of the outer bar portion 21 and the matched outer wall of size.When
It, can be to bilayer film material existing between the inside and outside wall of the two when the interior bar portion 22 is inserted into outer 21 inside of bar portion
Chucking power appropriate is formed, so that the interlayer of bilayer film material be made to form sealing.
Preferably, the length of the interior bar portion 22 is greater than or equal to the length of the outer bar portion 21.
Preferably, the sealing bar 2 is made of plastics.
It will be appreciated that rapid seal is not limited only to the structure of attached sealing bar shown in FIG. 12.Such as clips etc.
Sealing effect identical with sealing bar 2 also may be implemented in structure, and is also able to achieve Rapid reversal sealing.It will be understood, therefore, that figure
Sealing bar 2 shown in 1 is only preferred embodiment.
The bag body 1 of the water blockoff bag is made of flexible thin-film material, preferably by the compound of thickness 0.2mm to 0.5mm
The polyethylene or polypropylene plastic material of aluminum foil material or some strength are made.Bag body can by after a piece of material doubling
Open edge thermal compression welding and formed.Since above-mentioned material has excellent thermocompression bonding sealing characteristics, it can guarantee bag body
Stability and resistance to pressure with higher.
Preferably, the bag body is opposed by two panels previous materials, and forms seal line by thermal compression welding in surrounding.It is this
The mode of surrounding welding, due to longer seal line 11, when bag body internal material expands to form outside pressure,
It can crack simultaneously in surrounding and make internal material that expansion be rapidly completed.
Certainly, it if forming longer seal line 11 by more material piece thermal compression weldings, also will be helpful to quickly swollen
It is swollen.But relatively, the stability of bag body itself and resistance to pressure can also reduce, therefore needs and bag when designing length of sealing line
Body structural strength is balanced.
The chamber of bag body 1 is separated into two independent accommodating cavity A and accommodating by the cooperation of sealing bar 2 and bag body 1
Chamber B is respectively used to the component A and B component of perfusion two-part intumescent material.It, can depending on the difference matched needed for component A and B component
Sealing bar 2 to be arranged in the suitable position of bag body 1 according to space proportion, it is equal or not that accommodating cavity A and accommodating cavity B, which are divided,
Equal space.Preferably, accommodating cavity A and accommodating cavity B space proportion are matched with the volume ratio of component A and B component.
When sealing bar 2 is installed in bag body 1, can by outer bar portion 21 along bag body width direction (by accommodating cavity in bag body 1
Direction definition A and accommodating cavity B arranged side by side is the length direction of bag body, is width direction perpendicular to the length direction) it puts
The one side in the materials at two layers piece for forming bag body 1 is set, interior bar portion 22 is inserted along the another side for the materials at two layers piece for forming bag body 1
Enter outer bar portion 21, to the materials at two layers piece for forming bag body 1 is clamped between the outer bar portion 21 and interior bar portion 22, sealing bar
2 length be shorter than bag body 1 minimum widith, make accommodating cavity A and accommodating cavity B be located at sealing bar 2 both sides and mutually it is close
Insulate from.
Aforementioned two-part intumescent material is preferably the self-reactive polyurethane resin foamed material of property, can be in A
It 15~20 times of fast reaction foaming and intumescing or so and was consolidated into more high-strength within 10~30 second time after component and B component mixing
The macromolecule resin hardening thing of degree and toughness.Component A and B component sheet are as liquid material, suitable for passing through after the dismounting of sealing bar 2
The flowing of itself mutually quickly mixes.
In use, bag body 1 is extracted out from sealing bar 2, is unfolded, make the accommodating cavity A and accommodating cavity B two parts phase of bag body 1
It is logical, it is simply rubbed 5~10 seconds with hand, mixes component A and B component.Then rapidly by component A and the mixed bag of B component
Body 1 is placed in the channel of the cavity, hole that gush leak, the expanding material in bag body 1 can the expansion of quick autoreaction, and from hot weld
Bag body is strutted at seam, and continues rapid expanding and consolidates molding, and adapts to surrounding country rock situation and squeezes infiltration, to realize quick
Block the effect for gushing leak.
Preferably, component A and the mixed bag body 1 of B component can be strapped in a fixed link with adhesive tape, with convenient
It rapidly puts it into the channel of the cavity, hole that gush leak.Fixed link can be metal or wooden.
The utility model main function is: cavity or hole under deepwater environment gush that water leakage is larger, pressure is higher
In the case of, after first taking mould bag building stones filling cavity and hole, then water blockoff bag is gushed by above-mentioned be put into using mode of operation in time
In aquaporin, water blockoff bag internal expansion material itself fast reaction expansion, solidification form the consolidation of higher-strength and higher toughness
Body, quick blocking live penetrating passage, water-flowing path are cut off, to fast implement water blockoff purpose.
The size of self-expanding water blockoff bag can be customized to different size according to project situation, can primary multiple expansions
Water blockoff bag is used in combination, so as to realize that the quick blocking of the big water gushing channelway of complex condition gushes leak.
It is to be appreciated that describing the skill simply to illustrate that of the invention to what specific embodiments of the present invention carried out above
Art route and feature, its object is to allow those skilled in the art to can understand the content of the present invention and implement it accordingly, but
The present invention is not limited to above-mentioned particular implementations.All various changes made within the scope of the claims are repaired
Decorations, should be covered by the scope of protection of the present invention.
