Embodiment
The embodiment of the utility model is described in further detail below in conjunction with attached drawing.
Referring to shown in Fig. 1 to Fig. 3, the utility model embodiment provides a kind of cofferdam with Combined steel tube sheet pile, bag
Some steel pipe sheet piles 1 are included, which includes a steel pipe 2 and steel sheet pile 3, wherein, steel sheet pile 3 is cross bar stake, steel sheet pile
3 both ends are respectively provided with a fore shaft 33, and it is integral that two fore shafts 33 can mutually fasten shape, is offered along its length in steel sheet pile 3
One receiving space 34, the receiving space 34 divide steel sheet pile 3 for the first steel sheet pile 31 and the second steel sheet pile 32, wherein, this first
Steel sheet pile 31 is identical with 32 size of the second steel sheet pile, can make the ability to bear phase of the first steel sheet pile 31 and the second steel sheet pile 32
Together, ensure that the overall support capacity in cofferdam 4 is uniform, can also facilitate the installation of the steel pipe sheet pile 1, be carried out without specially choice direction
Installation, receiving space 34 is interior to be equipped with a steel pipe 2, and steel pipe 2 is respectively with the first steel sheet pile 31 and the second steel sheet pile 32 away from fore shaft 33
Sealed set is held, and two adjacent steel pipe sheet piles 1 are locked and are connected into the entirety of a cofferdam 4 successively by fore shaft 33, it is some by setting
Steel pipe sheet pile 1, and by some steel pipe sheet piles 1 lock connection it is integral, can solve that steel is used alone present in existing cofferdam 4
The problem of easily deforming during sheet pile, i.e., when steel sheet pile is used alone, support rigidity is smaller, opposite under equal soil pressure
The problem of moderate finite deformation can occur in other forms supporting, and individually use cost during steel-pipe pile higher, i.e., make integrally
During with steel-pipe pile, have the shortcomings that steel quantity consumption is big and cost is higher, pass through the steel pipe for setting steel pipe 2 and steel sheet pile 3 to combine to form
It is overall that sheet pile 1 forms cofferdam 4, it is possible to increase the supporting intensity in cofferdam 4, reduces the auxiliary equipment for being used for strengthening supporting intensity, phase
