In existing concrete structure, such as checkdam, reservoir, subway, culvert, sluice, the undergrounds such as tunnel, in Underwater Engineering, due to can not continuous placing or the distortion due to foundation settlement (earthquake), or the reason such as to expand with heat and contract with cold of the concrete component to cause due to the change of temperature, often deliberately deformation joint is left building, constuction joint, anti-seep measure will be taked in these gaps, prevent outside water or ground water seepage in structure space, present usual way is, between fist stage concrete and second stage concrete, concrete pit is set, maltha and copper sheet or rubber water-proof sheet is established in groove, but, this method needs concrete soil box in advance, can combine closely to make concrete pit and second stage concrete, need to carry out dabbing process to peripheral 3 faces of concrete pit, the duration will be extended like this and increase artificial, simultaneously because the general every segment length (highly) of concrete pit only has 50-100cm, distortion gap will be connected and composed by multiple concrete pit, therefore many transverse slots can be produced, and the irregular deformation of multiple concrete pit, phenomenon is emitted in the race that postorder can be caused to pour into maltha, and be difficult to cleaning, and adopt the technology replacing concrete pit with channel-section steel of number of patent application 2014100489253, although can cost saving and reduction of erection time than former construction method, but because channel-section steel will be deposited in dam body, cannot reuse, still cause waste, be therefore badly in need of a kind of equipment that can form die cavity at second stage concrete section.

Utility model content

In order to solve the problem, the utility model provides a kind of concrete work deformation joint vertical water-stopping structure, second stage concrete section preset go out a prefabricated chamber of semicircle, pour into pitch, and take out after the swaging die for arranging prefabricated chamber uses, can repeatedly use, adopt the vertical water-stopping structure of this structure can meet multiple 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 utility model provides following technical scheme:

The vertical water-stopping structure of a kind of concrete work deformation joint, comprise sealing piece and prefabricated chamber, it is characterized in that: sealing piece side is fixed in the middle part of fist stage concrete deformation joint section, opposite side protrudes and stretches in the prefabricated chamber of second stage concrete deformation joint section, is provided with pitch in prefabricated chamber.

Further, described sealing piece is rectangle copper sheet, the side being embedded in fist stage concrete deformation joint section part in advance is longitudinally provided with 90 ° of knuckles, and certain length outside the middle part that opposite side stretches out fist stage concrete deformation joint section, general half is embedded in fist stage concrete.

Further, described prefabricated chamber is semi-cylindrical die cavity, and inside is provided with pitch.

Further, the prefabricated chamber of described semi-cylindrical, for when second stage concrete is built, is provided with semicircle swaging die at fist stage concrete deformation joint, after second stage concrete solidifies, takes out swaging die, namely forms the prefabricated chamber of semi-cylindrical.

Further, the semi-cylindrical air bag composition that described swaging die is the reeded swaging die skeleton of band and is mated.

Further, described semi-cylindrical is provided with pitch in prefabricated chamber, and described pitch is No. 30 building asphalts, cools 2-12 hour after filling prefabricated chamber after melting.

Further, the both sides in described prefabricated chamber are also provided with bituminous felt between fist stage concrete section and second stage concrete section.

In order to make better adhesive in concrete prefabricated chamber of pitch, can be distributed with projection at swaging die external surface, projection can be round point shape, or the glazing bar in vertical or horizontal protrusion surface, concave point or groove can be formed in prefabricated chamber, to increase the adhesion stress of pitch after the demoulding.

The beneficial effects of the utility model

1. adopt prefabricated cavity configuration of the present utility model, make one, second stage concrete builds conveniently, section is neat;

2. hang out second stage concrete after swaging die use namely can reuse, can economize on resources and cut the waste;

3. can solve the leakage problems of the permanent seam in underground, the Underwater Engineering such as checkdam, reservoir, subway, culvert, sluice, tunnel;

4. compare with conventional construction method, because it does not need concrete soil box, the expenses such as artificial, mechanical, the template needed for concrete soil box can be reduced;

5., again because not needing reserved channel-section steel in inside, save metal material consumption;

6. adopt this method construction former working procedure on critical circuits, become non-key circuit operation, save the duration.Create very large economic benefit and social benefit.

7. the deformation joint seepage problem that the utility model technology can solve multiple ground condition/stratum differential settlement or the reason such as to expand with heat and contract with cold of the concrete component that causes due to the change of temperature causes; Also can prevent the section interface changing of the relative positions because the natural calamities such as earthquake cause, be out of shape the leakage problems caused.
