Description
Technical field
The utility model relates to technical field of bridge engineering.
Background technique
Enclose water-bound of the cofferdam as underwater support table, pile foundation construction later period are installed, and are cushion cap to draw water after back cover
Construction provides " dry environment ", and a kind of trend that Large Span Bridges have become bridge construction is built between great river, straits.But
Under complicated marine environment, due to climate variability, wind is big, wave is high, gushes the reasons such as anxious, and cofferdam, which is removed, bears and the comparable water in conventional inland river
It flows outside power, is also subjected to huge wave force.
Utility model content
The purpose of this utility model is for above-mentioned problem, to provide a kind of cofferdam under complicated marine environment, with energy
Enough reduce the structure that part wave force generates significant horizontal power to cofferdam.
In order to solve the above technical problems, the utility model provides a kind of cofferdam, comprising: side plate；Further include: inner support；
The side plate is connect with the inner support；
Side plate is double-walled construction, comprising: exterior panel, inside panel；Multiple first holes are offered on the exterior panel, it is described interior
Multiple second holes are offered on siding, the first hole forms access through exterior panel and inner wall sheet separation and the second hole, goes back on inside panel
It is provided with the second hole close mechanism.
Carrying out preferred technical solution to above-mentioned foundation structure is, the inner support is multilayer inner support.
Further preferred technical solution is that the inner support includes: upper, middle and lower-ranking inner support.
Technical solution still further preferably, which is that the multiple first hole is uniformly distributed, to be set on the exterior panel.
Further preferred technical solution is the oval pore structure in the first hole.
Further preferred technical solution is that the first hole of the oval pore structure is longitudinally opened in the side again
On the exterior panel of plate.
More preferred technical solution is that the side plate is double-walled steel construction.
The utility model has the beneficial effects that:
1. cofferdam provided by the utility model, several the first holes are provided on the exterior panel of side plate, first hole
The effect for the significant horizontal power that part wave force generates cofferdam can be effectively reduced, so that the utility model can be applicable in
In complicated marine environment.
2. the utility model is provided with several the second holes on the inside panel of side plate, the second hole is when later period cofferdam is transferred
It need to stay open, so that head difference is consistent inside and outside cofferdam, guarantee cofferdam structure safety.After the completion of the decentralization of cofferdam, lead to
It crosses the second hole close mechanism to block the second hole, then back cover, draws water, to provide " dry environment " for bearing platform construction.
3. cofferdam provided by the utility model has multilayer inner support, it can guarantee that cofferdam is tied under complicated marine environment
The stability of structure.

Specific embodiment
It is the technical means and efficacy reaching predetermined purpose of utility model and being taken for the utility model is further described, with
Lower combination attached drawing and preferred embodiment, to according to the utility model proposes cofferdam specific embodiment and working principle carry out
It is described in detail.
Cofferdam is integrally manufactured using batch production in the present embodiment.Its structure specifically includes that side plate 1, inner support 2.Side plate 1 with
Inner support 2 connects, and side plate 1 is double-walled construction, comprising: exterior panel, inside panel.Multiple first holes 9, inner wall are offered on exterior panel
Multiple second holes are offered on plate, the first hole forms access through exterior panel and inner wall sheet separation and the second hole, also sets on inside panel
It is equipped with the second hole close mechanism.
The purpose that the first hole 9 is arranged is: in complicated marine environment, cofferdam is subjected to huge wave force, passes through
First hole 9 is set, the effect for the significant horizontal power that part wave force generates cofferdam can be effectively reduced.
Be in the purpose that the second hole is arranged in inside panel: when later period cofferdam is transferred, the second hole needs to be kept open, water
It flows to reach behind the first hole 9 on exterior panel, the second hole on exterior panel and inner wall sheet separation, inside panel outside the side plate of cofferdam and enclose
In weir, keep head difference inside and outside cofferdam consistent, to guarantee cofferdam structure safety.
For the stability for reinforcing cofferdam structure, it is preferred that use multilayer inner support 2.Inner support 2 in the present embodiment uses
Be as shown in Figure 2 and Figure 3, comprising: upper, middle and lower-ranking inner support 2.
For side plate 1, it is preferred that use double-walled steel construction.
Setting for the first hole 9, it is preferred that multiple first holes 9 are uniformly distributed and are set on exterior panel.For first
The structure in hole 9, using oval-shaped pore structures as shown in Figure 4 in the present embodiment.First hole of oval pore structure is vertical
To being set on the exterior panel of side plate 1.
It should be noted last that the above specific embodiment is only to illustrate the technical solution of the utility model rather than limits
System, although the utility model is described in detail referring to example, those skilled in the art should understand that, it can be right
The technical solution of the utility model is modified or replaced equivalently, without departing from the spirit and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
