Abstract
The utility model discloses a kind of combination steel cofferdam, comprise main part and extention, described main part is Double-wall sin-gle-image radiography, and described extention is Larsen steel sheet-pile cofferdam; Described Double-wall sin-gle-image radiography comprises inside panel and exterior panel, and the bottom of described inside panel and exterior panel is connected to form the sword pin of closed compartment; Described Double-wall sin-gle-image radiography adopts fore shaft to be connected with described Larsen steel sheet-pile cofferdam joint portion, drag hook type fore shaft is welded with at the exterior panel external surface of described Double-wall sin-gle-image radiography and Larsen steel sheet-pile cofferdam link position, described drag hook type fore shaft can be engaged mutually with Larsen steel sheet pile self drag hook type fore shaft, fore shaft lap position forms water shutoff storehouse, with the shutoff of M25 flocculation mortar in water shutoff storehouse.The utility model is applicable to large area labyrinth deepwater foundation construction and has good, the impermeable advantage of resistance to overturning.
Description
Technical field
The utility model relates to a kind of combination steel cofferdam of deepwater foundation construction.
Background technology
Along with China is in the large scale investment of foundation construction field, cross over river in a large number, extra large grand bridge is built one after another, and these grand bridges often needs to build huge pier footing in deep water.In order to create good environment to the construction of pier footing, need to carry out cofferdam construction.The deepwater foundation construction cofferdam overwhelming majority of current pier footing adopts steel cofferdam, and Double-wall sin-gle-image radiography, steel sheet-pile cofferdam are deep water construction Common Steels cofferdam, and they have respective advantage but also have respective shortcoming.The advantages such as Double-wall sin-gle-image radiography has that integral rigidity is large, barrier properties good, suitable large area deep water is gone along with sb. to guard him, but due to volume large, be generally arranged to the flat shape of circle, ellipse or regular polygon, be not suitable for the space enclosing structure as flat shape complexity; Steel sheet-pile cofferdam have lightweight, cost is low, can be spliced into the advantage of various shape, but its globality rigidity is less, easily tilts, and needs to arrange strong and close inner support, is not suitable for as large-area deep water space enclosing structure; Easily there is infiltration in different cofferdam binding site in addition.Therefore, lack a kind of good seepage-proof property at present, and can be used as the steel cofferdam that large area labyrinth deep water goes along with sb. to guard him.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide and is a kind ofly applicable to large area labyrinth deepwater foundation construction and the combination steel cofferdam that resistance to overturning is good, antiseepage is good.
For achieving the above object, the utility model have employed following technical scheme:
A kind of combination steel cofferdam, comprise main part and extention, described main part is Double-wall sin-gle-image radiography, and described extention is Larsen steel sheet-pile cofferdam; Described Double-wall sin-gle-image radiography comprises inside panel and exterior panel, and the bottom of described inside panel and exterior panel is connected to form the sword pin of closed compartment; Described Double-wall sin-gle-image radiography adopts fore shaft to be connected with described Larsen steel sheet-pile cofferdam joint portion, drag hook type fore shaft is welded with at the exterior panel external surface of described Double-wall sin-gle-image radiography and Larsen steel sheet-pile cofferdam link position, described drag hook type fore shaft can be engaged mutually with Larsen steel sheet pile self drag hook type fore shaft, fore shaft lap position forms water shutoff storehouse, with the shutoff of M25 flocculation mortar in water shutoff storehouse.
As preferably, in the compartment that described inside panel and described exterior panel are formed, be provided with support member and the partition panel of some connection inside panels and exterior panel.
As preferably, in described Larsen steel sheet-pile cofferdam, be provided with truss inner support.
As preferably, described support member comprises the angle steel diagonal brace of level is located at the inwall ring flat-plate of inside panel lateral surface, corresponding inwall ring flat-plate is located at exterior panel medial surface outer wall ring flat-plate and the described inwall ring flat-plate of some connections and outer wall ring flat-plate.
As preferably, in described Double-wall sin-gle-image radiography, be provided with cofferdam leading truck and cofferdam suspension centre.
As preferably, described Double-wall sin-gle-image radiography and Larsen steel sheet-pile cofferdam link position are provided with stiffener, and one end of described stiffener is welded on the external surface of described exterior panel, and the other end is welded on the longeron of steel sheet pile.
As preferably, in described sword pin, pour into pea gravel concreten.
The beneficial effects of the utility model: by Double-wall sin-gle-image radiography and Larsen steel sheet-pile cofferdam are combined, the advantage that large, the suitable large area structure of the existing integral rigidity of combination steel cofferdam of the present utility model is gone along with sb. to guard him also has the advantage that suitable labyrinth is gone along with sb. to guard him; The binding site in other two kinds of cofferdam is connected by fore shaft, has the advantage of good seepage-proof property.
