Abstract
The utility model discloses a major diameter round steel sheet pile cofferdam in water. The major diameter round steel sheet pile cofferdam comprises steel sheet piles, a bearing platform and surrounding purlins. The steel sheet piles are continuously and evenly arranged around the bearing platform with the bearing platform as the center in a round and integral mode to form a cofferdam wall. The bearing platform is lower than the cofferdam wall, and the steel sheet piles are punched into a soil layer to form a steel sheet pile support structure. The two ends of each steel sheet pile are provided with locking openings. The steel sheet piles are meshed with one another to be connected and fixed through the locking openings. The seven layers of surrounding purlins are arranged on the cofferdam wall, are evenly and annularly arranged along the cofferdam wall at intervals and are parallel to the cofferdam wall. The surrounding purlines are connected through polygon H-shaped steel. Triangular support-shaped bracket beams and steel tube stand columns are arranged between the surrounding purlines to play a connecting and supporting role. The steel tube stand columns are arranged in a circular mode with the bearing platform as the center. The major diameter round steel sheet pile cofferdam in water has the advantages that construction and operation are easy and convenient, the bearing platform in water is constructed conveniently, and the inner supporting stress of the cofferdam is even and stable.
Description
Technical field
The utility model relates to the construction field that builds a bridge, and relates in particular to large-diameter circular steel sheet-pile cofferdam in a kind of water.
Background technology
At present, along with social development, the fields such as bridge and building are also in quick progress, and in bridge construction, cofferdam is a kind of must using, in prior art, the operation platform area in cofferdam is large, material usage is large, thereby has caused construction cost high, and has increased difficulty of construction.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide large-diameter circular steel sheet-pile cofferdam in a kind of water.
The utility model takes following technical scheme to realize: large-diameter circular steel sheet-pile cofferdam in a kind of water, and it comprises steel sheet pile, cushion cap and encloses purlin, described steel sheet pile rounded continuous entirety centered by cushion cap is evenly arranged in cushion cap and forms cofferdam wall around; Described cushion cap height is lower than cofferdam wall; Described steel sheet pile is squeezed into soil layer and is formed steel sheet pile supporting and protection structure; Described steel sheet pile two ends are provided with fore shaft; Described steel sheet pile relies on the mutual interlock between fore shaft and is connected and fixed; Described cofferdam wall is provided with seven layers and encloses purlin; The described purlin that encloses is along the even interval of cofferdam wall circular array, and parallel with cofferdam wall; Described enclosing between purlin is to connect to form for polygon I-steel; Described enclosing is provided with Tripod bracket beam between purlin and is connected support with steel pipe post; The rounded arrangement of described steel pipe post and centered by cushion cap; Described steel sheet pile adopts Larsen IV steel sheet pile, and all the other cofferdam are stainless steel with steel; Described support post is steel pipe, between adopt shaped steel connect; Described first, second and third road supports and encloses purlin and adopt single shaped steel of spelling, and fourth, fifth, six, seven roads support and enclose purlin and adopt Two bors d's oeuveres type shaped steel; Described cofferdam back cover geology is permeable fine sand layer, and adopts underwater concrete pouring cofferdam back cover.
The utlity model has in sum following beneficial effect: it is simple and easy to do to the utlity model has constructing operation, the stressed advantage such as uniform and stable of the convenient and cofferdam inner support of underwater support table construction, and adopt circular cofferdam to reduce the minimizing of operation platform area; In circular cofferdam, support without transverse and longitudinal is staggered, thereby cushion cap reinforcing bar, concrete handling construction are accelerated to bearing platform construction progress without impact, the bearing platform construction time under water that shortens is reduced construction cost.

Detailed description of the invention
As shown in Figure 1, large-diameter circular steel sheet-pile cofferdam in a kind of water, it comprises steel sheet pile 1, cushion cap 2 and encloses purlin 3, described steel sheet pile 1 rounded continuous entirety centered by cushion cap 2 is evenly arranged in cushion cap 2 and forms cofferdam wall 10 around, and steel sheet pile 1 and enclosing between purlin 3 by steel plate or short steel pipes support top, thereby ensure circular steel sheet pile 1 outside pressure to be delivered to annular, to enclose purlin 3 stressed; Described cushion cap 2 height are lower than cofferdam wall 10; Described steel sheet pile 1 is squeezed into soil layer and is formed steel sheet pile supporting and protection structure, can play good protective action; The mutual interlock of fore shaft 13 that described steel sheet pile 1 two ends arrange, steel sheet pile 1 body of wall of circular continuous entirety can water proof and gear native; Described cofferdam wall 10 is provided with seven layers and encloses purlin and enclose purlin along cofferdam wall 10 even interval circular array; The described polygon I-steel 12 arranging between purlin 3 that encloses can play support, anti-soil and resist the effect of water lateral pressure; Described enclosing is provided with Tripod bracket beam 11 between purlin 3 and is connected support with steel pipe post 14, and the Tripod bracket beam 11 of setting can play supporting steel sheet pile 1 and transmit the vertical force of steel sheet pile 1 and the effect of horizontal force, thereby has increased the stability of steel sheet pile 1.
The above is the utility model embodiment, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
