It is single structure, the support rigidity of the steel sheet pile of this structure is smaller, relative to other forms branch under same soil pressure
The sedimentation and deformation that moderate finite deformation can be occurred, while cause foundation pit surrounding soil big by protecting can not to endanger foundation pit Adjacent Buildings
Meet the requirement in some places.
Utility model content
In view of the deficiencies in the prior art, the purpose of this utility model is to provide one kind having combination shaped steel plate pile
Cofferdam, the supporting intensity of single steel sheet pile can be improved.
To achieve the above objectives, the technical scheme adopted by the utility model is that：A kind of cofferdam with combination shaped steel plate pile,
Including：
Several combination piling bars, each combination piling bar includes a drum steel and steel sheet pile, and the steel sheet pile both ends are respectively set
There are a fore shaft, the drum steel to be attached at the steel plate stake body along the steel sheet pile length direction；
The adjacent combination piling bar is locked successively by the fore shaft is connected into the cofferdam entirety.
Based on the above technical solution, the steel sheet pile is shape for hat stake.
Based on the above technical solution, the drum ladle includes two wing plates and a web, wherein a wing plate patch
Set on the steel plate stake body, the web is perpendicular to the steel plate stake body.
Based on the above technical solution, the wing plate for being attached at the steel plate stake body is attached at the steel sheet pile
In the middle part of pile body.
Based on the above technical solution, the drum steel is set to the side of steel sheet pile protrusion.
Based on the above technical solution, the length of the drum steel be 24000mm, width 300mm, a height of 800mm,
The length of the steel sheet pile is 24000mm, width 900mm, a height of 240mm.
Compared with prior art, the utility model has the advantage of：
(1) a kind of cofferdam with combination shaped steel plate pile in the utility model, by carrying out drum steel and steel sheet pile
In conjunction with, can enhance the supporting intensity of steel sheet pile, reduce ordinary steel sheet pile due to slight insufficient and caused by being built around foundation pit
The harm for building object, makes that it is suitable for different places.

Fig. 3 is the side view that piling bar is combined in the utility model embodiment；
Fig. 4 is the structural schematic diagram in cofferdam in the utility model embodiment；
In figure：1- combines piling bar, 2- drum steel, 21- wing plates, 22- webs, 3- steel sheet piles, 31- fore shafts, the cofferdam 4-.
Specific implementation mode
The embodiments of the present invention are described in further detail below in conjunction with attached drawing.
Shown in Figure 1, the utility model embodiment provides a kind of cofferdam with combination shaped steel plate pile, including several groups
Piling bar 1 is closed, each piling bar 1 that combines includes a drum steel 2 and steel sheet pile 3, and steel sheet pile 3 is shape for hat stake, and drum steel 2 includes two wing plates
21 and a web 22, wherein a wing plate 21 is attached at 3 pile body of steel sheet pile, using interrupted between 3 pile body of the wing plate 21 and steel sheet pile
Fillet welding is fixed, the web 22 of drum steel 2 perpendicular to 3 pile body of steel sheet pile, this kind of combination can piling scene or its
Nearby processing site is welded for he, is convenient for the transport and storage of the combination piling bar 1, moreover it is possible to be designed according to site contour different
The welding manner of steel sheet pile 3 and drum steel 2, and the wing plate 21 for being attached at 3 pile body of steel sheet pile is attached in the middle part of 3 pile body of steel sheet pile,
3 supporting intensity of steel sheet pile of 2 both sides of drum steel can be made identical, be further ensured that the whole support capacity in cofferdam 4 is uniform, keep away
Exempt to occur that a certain position supporting intensity is relatively low to be damaged so as to cause the position, support capacity is lost so as to cause the cofferdam 4.
Shown in Fig. 1 to Fig. 4,3 both ends of steel sheet pile are respectively provided with a fore shaft 31, and drum steel 2 is pasted along 3 length direction of steel sheet pile
Set on 3 pile body of steel sheet pile, it is preferred that drum steel 2 is set to the side that steel sheet pile 3 protrudes, and can be the combination piling bar 1 has bigger
Rigidity, and two adjacent combination piling bars 1 lock that be connected into a cofferdam 4 whole by fore shaft 31 successively, pass through and several steel pipes are arranged
Sheet pile 1, and the locking connection of several steel pipe sheet piles 1 is integral, it can solve to use ordinary steel sheet pile present in existing cofferdam 4
When the problem of easily deforming, i.e., support rigidity is smaller when using ordinary steel sheet pile, relative to it under same soil pressure
The problem of moderate finite deformation can occur for its form supporting combines 1 shape of combination piling bar formed by the way that drum steel 2 and steel sheet pile 3 is arranged
It is whole at cofferdam 4, the supporting intensity in cofferdam 4 can be improved, the auxiliary equipment for being used for enhancing supporting intensity is reduced, it is corresponding to reduce
Cost, and this is simple in structure, easy construction, can shorten the construction period accordingly.
Shown in Fig. 2 to Fig. 4, further, adjacent fore shaft 31 fits closely when being connected at the fore shaft 31 of connection, equal nothing
Need Concrete Filled can sealing, can reduce cost, the length of drum steel 2 is 24000mm, width 300mm, a height of 800mm,
The length of steel sheet pile 3 is 24000mm, width 900mm, a height of 240mm.
