Description
Technical field
The present invention relates to a kind of underground/submerged structure water-tight device, particularly to a kind of concrete works swaging die air bag
And manufacture method.
Background technology
In existing xoncrete structure, the such as underground such as checkdam, cistern, subway, culvert, sluice, tunnel, under water
In engineering, due to can not continuous placing or the deformation due to settlement of foundation (earthquake), or the coagulation caused due to the change of temperature
The reason such as expand with heat and contract with cold of soil component, the most deliberately leaves movement joint, construction joint pouring, and these gaps antiseep to be taked is arranged
Executing, prevent external water or subsoil water from leaking in structure space, present usual way is, at fist stage concrete and second phase coagulation
Concrete pit is set between soil, in groove, sets maltha and copper sheet or rubber water-proof sheet, but, this method needs precast concrete in advance
Groove, in order to make concrete pit can combine closely with second stage concrete, needs 3 faces peripheral to concrete pit to carry out dabbing process, this
Sample will extend the duration and increase artificial, simultaneously because the most every segment length of concrete pit (highly) only has 50-100cm, deformation
Gap to be connected and composed by multiple concrete pits, therefore can produce a plurality of transverse slot, and multiple concrete pit is irregular
Deformation, can cause the race of postorder perfusion maltha to emit phenomenon, and be difficult to clean up；And use number of patent application 2014100489253
With channel-section steel replace concrete pit technology, although expense and reduction of erection time can be saved than former construction method, but due to groove
In steel dam body to be deposited in, it is not possible to recycling, still causing waste, being therefore badly in need of one can be at second stage concrete section
Precast the equipment putting the die cavity holding Colophonium.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of concrete works swaging die air bag and manufacture method thereof, permissible
Second stage concrete section preset go out a semicircle die cavity, in die cavity, pour into Colophonium can play sealing effect, and carry
The swaging die having this air bag takes out and can repeatedly use after using, and uses the vertical water sealing structure of this technology can meet many
Plant ground condition/stratum differential settlement or the changing of the relative positions, telescopic displacement etc., Master Cost and reduction of erection time can be saved.
For achieving the above object, the present invention provides following technical scheme:
A kind of concrete works swaging die air bag, including hollow gasbag body, it is characterised in that:
Described air bag is semi-cylindrical, and the middle part of its semi-cylindrical plane is provided with air bag groove, described along its length

Described air bag upper end is provided with valve cock, and lower end sets the Packed end；
Reinforcing fiber silk it is mingled with in the cyst wall of described air bag；
In order to make Colophonium more preferably can be distributed with projection in air bag circular arc external surface the adhesive of concrete-type intracavity,
Projection can be round point shape, or in the vertical or horizontal glazing bar protruding surface, can form concave point or recessed after the demoulding in die cavity
Groove, to increase the cohesive force of Colophonium.
Described air bag groove walls, air bag planar wall and air bag two side wall thickness is more than air bag antetheca, and two side is forward
Wall circular arc is the most thinning.
The manufacture method of described concrete works swaging die air bag, including following technique: first make semicircle air bag
Mould, arranges reinforcing fiber silk in mould, with castable rubber molding, the demoulding, high frequency welding bottom surface, lower end and upper surface
Valve cock i.e. obtains air bag.
The invention also discloses the using method of above-mentioned concrete works swaging die air bag, comprise the steps:
1) assembling of swaging die: air bag groove is directed at skeleton groove, is arranged on bottom air bag on skeleton base, is positioned at gas
The fixing point of capsule backward plane is equipped with to be assembled integrally in the fixing hole that skeleton is corresponding and i.e. forms swaging die；
2) setting of swaging die: after fist stage concrete solidification, the groove of skeleton is stuck on the sealing piece of protrusion, at skeleton
Both sides concrete cross section on bituminous felt is set；
3) air bag pressurization: add compressed air, air bag from the valve cock being arranged on air bag top in the air bag set
Form certain air pressure；
4) second stage concrete pours: after setting air bag pressure and template, second stage concrete pours according to highl stratification, often
Secondary every layer of about 50cm, waits lower floor's initial set to pour last layer again after having certain degree of hardness, until it reaches the height of needs；
5) die cavity is formed: after second stage concrete initial set, releases air bag internal gas pressure, arranges suspension hook in the lifting hole(eyelet) of skeleton,
Hang out swaging die, form semicircle die cavity at second stage concrete section part；
6) asphalt reperfusion: fill molten asphalt in semicircle die cavity, cool down；
7) when arranging multiple movement joint, repeat the above steps 1-6, Colophonium does once perfusion or irrigates for several times；Hang out
Swaging die is cleared up in time, is maintained, and stores, in order to recycling.
Beneficial effects of the present invention
Compared with prior art, the beneficial effect comprise that
1. use the die cavity preset mode of this air bag so that one, second stage concrete pour conveniently, section is neat；
2. hanging out second stage concrete after swaging die use i.e. can reuse, can economize on resources minimizing waste；
3. can solve the permanent seam in underground, the Underwater Engineering such as checkdam, cistern, subway, culvert, sluice, tunnel
Leakage problems；
4. compare with conventional construction method, because it is not required to concrete soil box, it is possible to reduce needed for concrete soil box
Manually, the expense such as machinery, template；
The most again because being not required to reserved channel-section steel in inside, save metal material consumption；
6. use this method construction the working procedure on critical circuits in the past, become non-key circuit operation, save
Duration.Create the biggest economic benefit and social benefit.
7. the coagulation that the technology of the present invention can solve multiple ground condition/stratum differential settlement or the change due to temperature causes
The deformation joint seepage problem that the reason such as expand with heat and contract with cold of soil component causes；Can also prevent because of breaking that the natural disasters such as earthquake cause
The leakage problems that the face interface changing of the relative positions, deformation cause.
