Description
Technical field
The present invention relates to a kind of underground/submerged structure water-tight device, more particularly to a kind of concrete works swaging die air bag
Application method.
Background technology
In existing concrete structure, for example, it is the underground such as checkdam, cistern, subway, culvert, sluice, tunnel, underwater
In engineering, due to being unable to continuous placing or the deformation due to settlement of foundation (earthquake), or the coagulation caused by the change of temperature
The reason such as expand with heat and contract with cold of native component, deliberately leaves movement joint, construction joint, these gaps will take antiseep to arrange often pouring
Apply, prevent external water or underground water from leaking into structure space, present usual way is, in fist stage concrete and the second stage of coagulation
Concrete pit is set between soil, maltha and copper sheet or rubber water-proof piece are set in groove, however, this method needs advance precast concrete
Groove, in order that concrete pit and second stage concrete can combine closely, it is necessary to carry out dabbing processing to peripheral 3 faces of concrete pit, this
Sample will extend the duration and increase is artificial, simultaneously because concrete pit typically only has 50-100cm per segment length (height), deform
Gap will be connected and composed by multiple concrete pits, therefore can produce a plurality of transverse slot, and multiple concrete pits is irregular
Deformation, the race of postorder perfusion maltha can be caused 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 than former construction method can save expense and shorten the duration, due to groove
Steel will be deposited in dam body, it is not possible to reused, still caused to waste, therefore urgent need one kind can be in second stage concrete section
Precast the equipment for putting the die cavity for holding pitch.
The content of the invention
In order to solve the above problems, the present invention provides a kind of application method of concrete works swaging die air bag, Ke Yi
Second stage concrete section it is preset go out a semicircle die cavity, pitch is poured into die cavity can play sealing effect, and carry
The swaging die of this air bag can be repeatedly used using rear taking-up, can be met using the vertical water sealing structure of this technology a variety of
Ground condition/stratum differential settlement or the changing of the relative positions, telescopic displacement etc., Master Cost can be saved and shorten the duration.
