Abstract
The invention relates to a construction method of a supporting type concrete deformation joint water-stop cavity die. The cavity die comprises a movable frame and a support. The support is arranged in the movable frame and fixed to the movable frame into a whole through a fastener. When the cavity die is applied, the opening face of the cavity die is in butt joint with and is embedded in a water-stop piece at the first-stage concrete section. The water-stop piece is arranged in the middle of the support. When second-stage concrete is poured, after second-stage concrete is initially set, the fastener is detached, and after the support and the movable frame are hoisted out, a cavity for injecting molten asphalt is formed in the second-stage concrete.
Description
Technical field
The present invention relates to a kind of underground/submerged structure water-tight device, more particularly to a kind of brace type deformed concrete crack stops
The construction method of water swaging die.
Background technology
In existing concrete 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, movement joint, construction joint are deliberately left pouring often, and these gaps will take antiseep to arrange
Apply, in preventing 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 treatment to 3 faces of concrete pit periphery, this
Sample will extend the duration and increase artificial, simultaneously because concrete pit is general to only have 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 pit is irregular
Deformation, the race that postorder can be caused to irrigate maltha emits phenomenon, and is 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 shortening the duration, but due to groove
Steel will be deposited in dam body, it is not possible to reused, and still cause 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 construction party of brace type deformed concrete crack sealing swaging die
