Abstract
A kind of device that utilizes air bag to carry out Double-Wall Steel Boxed Cofferdam dismounting, comprise Double-Wall Steel Boxed Cofferdam to be removed, Double-Wall Steel Boxed Cofferdam is positioned at below waterline, it comprises the double wall concrete of bottom and the double wall on top, between double wall concrete and double wall, by flange bolt device, be connected, described flange bolt device comprises the flange that is arranged on respectively double wall concrete and double wall opposite sides, between two flanges, waterstop pad is installed, and two flanges are connected and fixed by many groups high-strength bolt in the outside of double wall; Double wall outside is provided with many group aerofoil profile plates, and the downside of aerofoil profile plate is provided with air bag, and gas tube one end connects air bag, more than the other end reaches waterline.While removing cofferdam, by diver, the high-strength bolt between double wall concrete and double wall is excised, then utilize aerating device to airbag aeration, the buoyancy that air bag provides holds up cofferdam and pays the water surface, then carries out cutting waterborne.By this scheme, remove both arms steel cofferdam, significantly reduced the intensity of subaqueous construction, can effectively increase work efficiency, reduce construction risk.
Description
Technical field
The utility model relates to a kind of Double-Wall Steel Boxed Cofferdam, is specially a kind of device that utilizes air bag to remove Double-Wall Steel Boxed Cofferdam.
Background technology
Double-Wall Steel Boxed Cofferdam, as the water-retaining structure of deep-water bridge foundation construction, is widely used in bridge construction.It is sealed into underwater foundation construction by bottom concrete and self wall body dry execution conditions is provided.Double-Wall Steel Boxed Cofferdam is monolithic construction at present, and the following part in coxopodite riverbed has all been built double wall concrete, to increase its sinking ability, in the middle of the above part in riverbed, conventionally pours water.After foundation construction completes in water, conventionally by diver, dived beneath the water and do not carried out cutting whole into sections in water to building double wall concrete part cofferdam, the mode that recycling boom hoisting carries out lifting by crane in water is removed.This expense of cutting disassembling method is under water high, efficiency is low and have great potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of device that utilizes air bag to carry out Double-Wall Steel Boxed Cofferdam dismounting, and the application by this platform can reduce the unnecessary length of steel casing, reduces construction cost, guarantees construction quality.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of device that utilizes air bag to carry out Double-Wall Steel Boxed Cofferdam dismounting, comprise Double-Wall Steel Boxed Cofferdam to be removed, Double-Wall Steel Boxed Cofferdam is positioned at below waterline, it comprises the double wall concrete of bottom and the double wall on top, between double wall concrete and double wall, by flange bolt device, be connected, described flange bolt device comprises the flange that is arranged on respectively double wall concrete and double wall opposite sides, between two flanges, waterstop pad is installed, two flanges are connected and fixed by many groups high-strength bolt in the outside of double wall; Double wall outside is provided with many group aerofoil profile plates, and the downside of aerofoil profile plate is provided with air bag, and gas tube one end connects air bag, more than the other end reaches waterline.
The inner side of described aerofoil profile plate is fixedly connected with double wall, and is provided with deep floor below aerofoil profile plate, makes it have larger rigidity; The outside of aerofoil profile plate is with downward radian or connect downward flap, can play a protective role to air bag, has certain position-limiting action simultaneously.In addition, in aerofoil profile plate inner side, be provided with retainer ring, air bag is provided with pulling eye outward, and retainer ring is connected with pulling eye.
In the double wall of described mounting flange position, be provided with stiffener, for improving the rigidity at this position.
Described waterstop pad, for adopting elastomeric material to make, by the design of waterstop pad, guarantees its sealing effectiveness.
The utility model is owing to adopting said structure, after construction, in the time of need to removing cofferdam, by diver, the high-strength bolt between double wall concrete and double wall is excised, then utilize aerating device to airbag aeration, the buoyancy that air bag provides holds up cofferdam and pays the water surface, then carries out cutting waterborne.By this scheme, remove both arms steel cofferdam, significantly reduced the intensity of subaqueous construction, can effectively increase work efficiency, reduce construction risk.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
