Description
Technical field
The present invention relates to a kind of underground/submerged structure water-tight device, more particularly to a kind of gasbag-type concrete works deformation
The construction method of seam sealing swaging die.
Background technology
In existing xoncrete structure, such as underground such as checkdam, cistern, subway, culvert, sluice, tunnel, under water
In engineering, due to being unable to 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 native component, deliberately leave often movement joint pouring, and these gaps will take anti-seep measure, prevent
External water or subsoil water are leaked in structure space, and present usual way is set between fist stage concrete and second stage concrete
Concrete pit is put, maltha and copper sheet or rubber water-proof piece are set in groove, however, this method needs advance concrete soil box, be
Enable concrete pit to combine closely with second stage concrete, need to carry out dabbing process to 3 faces of concrete pit periphery, thus can
Extend the duration and increase artificial, simultaneously because concrete pit is general to only have 50-100cm per segment length (height), deformation gap will
Connected and composed by multiple concrete pits, therefore a plurality of transverse slot, and the irregular deformation of multiple concrete pits, meeting can be produced
The race for causing postorder perfusion maltha emits phenomenon, and is difficult to clean up；And adopt number of patent application 2014100489253 with channel-section steel
Replace the technology of concrete pit, although can save expense and reduction of erection time than former construction method, but because channel-section steel will be retained
In dam body, it is not possible to reuse, still cause to waste, therefore urgent need one kind can precast in second stage concrete section and put
Hold the die cavity equipment of Colophonium.
The content of the invention
In order to solve the above problems, the present invention provides a kind of construction of gasbag-type concrete works movement joint sealing swaging die
