Description
Technical field
The present invention relates to a kind of annular air-pocket, relate to a kind of air bag that when piling seals pile body and other member in water specifically.
Background technology
In bridge, harbour, power plant construction, usually run in water and drive piles, on pile body, make the construction of cushion cap, when bearing platform prefabrication, need be installed on the pile body with the box-type member of some steel boxes, casing class, as the cofferdam of the mould or the prefabricated cushion cap of prefabricated cushion cap, portion makes cage of reinforcement fluid concrete or rack template within it.The member of these steel boxes, casing class is very big, little then tens of cubic meters, greatly then tens thousand of cubic meters.A cushion cap needs a plurality of pile bodies to support, the logical bridge of picture Soviet Union, a cushion cap needs more than 130 steel pipe pile to support, want correspondence to open a plurality of holes on the member base plate of each steel box, casing class, owing to consider the deviation of piling and the deviation of perforate, for ease of laying these members, the pile body hole of its base plate will be opened greatly, make that the space in pile body and hole is very big, water will enter in the casing by the space, and the water that get rid of in the casing at first will seal the space between hole and the pile body.
Present water-stopping method is at several steel plates that coincide with stake of the hole of base plate loam cake haply, to reduce the space between hole and the pile body, sometimes also will be at the end welding hinge of steel plate for the impact that prevents wave, what also have adds cranse on steel pipe pile, these methods can not play the effect of complete sealing, also to pour into a mould very thick bottom concrete, the employing that has polyurethane foam shutoff under water or expanded rubber leak stopping.These all need diver's underwater operation.Especially in the abominable engineering of execution conditions since surge big, current are anxious, under the situation of the depth of water, usually can cause the sealing failure.Constructional difficulties, the cycle is long, cost is high, the cast bottom concrete can pollute the construction waters, be a unsolved always difficult problem.
Summary of the invention
Problem to be solved by this invention provides a kind of annular air-pocket, can solve the problem that seals between the object effectively, especially solves the difficult problem of the sealing of the sealing between the casing and pile body in the water.
For addressing the above problem, the present invention by the following technical solutions:
A kind of annular air-pocket is characterized in that: the cross section of described annular air-pocket is a rectangle.
Below be the technical scheme of further improvement in the technical proposal:
Its ratio of width to height of the square-section of described annular air-pocket is 1: 1～10.
Its ratio of width to height of the square-section of described annular air-pocket is 1: 3～6.
The square-section of described annular air-pocket has chamfering.
Its each chamfering of the square-section of described annular air-pocket is an arc angling.
Its upper and lower end parts of the square-section of described annular air-pocket is an arc.
It is shaped as rectangle the neighboring of described annular air-pocket, and it is shaped as rectangle or circle or polygon inner rim.
It is shaped as circle the neighboring of described annular air-pocket, and it is shaped as rectangle or polygon inner rim.
It is shaped as circle the neighboring of described annular air-pocket, and it is shaped as eccentric circle inner rim.
Described annular air-pocket comprises casing play.
Described casing play is arranged in the layer of annular air-pocket, that is to say that the utricule of annular air-pocket is divided into sandwich construction, wherein contains casing play.
The material of described annular air-pocket is rubber or plastics or kiss-coating cloth or kiss-coating cord fabric or film-coated fabrics or synthetic leather.
Annular air-pocket mouth of the present invention can be respectively in inboard, the outside of air bag, and Valve for aerocyst can also be a bending, and the setting of Valve for aerocyst is not limited to above-mentioned form certainly, also can be arranged on other positions that can be provided with such as top.
Air bag cross section and outer peripheral shape are by sulfurizing mould or molding fetal and production method decision.Air bag is the various cross sectional shapes that presented under the small air pressure charging into, and along with air bag inflation pressure increases gradually, its any cross section and outer peripheral shape all can trend towards circle under no external force constraint.
And that exoskeletal air bag bears pressure is less, and this class air bag girth under gas pressure alters a great deal, and general elongation rate is in 6%～200%, and it mainly is to realize stagnant water effect by the change that girth elongation, sectional area become big and shape.
The above-mentioned variation that the present invention is listed is not limited only to above-mentioned form of structure, based on design of the present invention brought other for industry those of ordinary skill without the variation that creative work brought, should be within protection scope of the present invention.
Technical scheme of the present invention can be made up according to the shape of the shape of pile body and its corresponding member and be changed.
Beneficial effect, the present invention adopts said method, the air bag of the design comparison circular cross-section of square-section have contact area big, contact advantage closely, therefore sealing effectiveness is better, can convenient installation in narrow and small slit and equidistant slit, the advantage that the mould manufacturing is simple, expense is low of good, the large-scale air bag of positioning performance; The design of corners and fillets can reduce the stress of corner and concentrate, also be convenient to moulding, manufacturing, the difform design of inner rim and neighboring can adapt to the periphery for difform pile body and with the difform needs of the member of its sealing, reach better sealing effectiveness.
The invention will be further described below in conjunction with drawings and Examples:
