Description
Technical field
The utility model relates to a kind of steel sheet pile cofferdam structure.
Background technology
Along with high-grade highway, generally the building of railway, get more and more across river, bridge engineering for sea-crossing, for underwater support table construction, the construction technology adopting steel sheet-pile cofferdam to carry out water proof more and more becomes the focus of concern.When bearing platform construction position water is darker, cushion cap bottom surface, more than mud face, needs design bearing platform construction template separately, and normal the laying with cofferdam inner support of bearing platform construction template position is conflicted, and increases steel sheet-pile cofferdam design difficulty.In addition, during steel sheet pile cofferdam construction, steel sheet pile inserted to play verticality is difficult to control, and adopts common individual layer guiding construction technology often to occur the phenomenons such as steel sheet pile inserted to play off normal, inclination.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art, provides a kind of steel sheet pile cofferdam structure, adopts this structure effectively can control the vertical precision of steel sheet pile, inner support and cushion cap bed die can be united two into one simultaneously, improve operating efficiency, saved cost.
For achieving the above object, the utility model adopts following technical proposals:
A kind of steel sheet pile cofferdam structure, it comprises the multiple steel sheet piles being arranged on foundation ditch surrounding, location steel pile tube outside the steel sheet-pile cofferdam arranged outside that steel sheet pile is formed, planar positioning structure outer end, upper strata is fixedly connected with location steel pile tube top, outside and the other end holds out against steel sheet pile in the horizontal direction arranges, inner side location steel pile tube is provided with inside steel sheet-pile cofferdam, upper strata enclose purlin be fixedly connected on inner side location steel pile tube and steel sheet-pile cofferdam between top, purlin is enclosed on upper strata and multiple upper stratas steel inner support is fixedly linked, four brackets are symmetrically welded with vertically on the every root steel pile casting top being positioned at steel sheet pile, well ellbeam formula lower floor precast concrete inner support is set up on bracket, each end of well ellbeam formula lower floor precast concrete inner support is all enclosed purlin by built-in fitting and lower floor and is fixedly linked, lower floor encloses purlin and is fixed on the inwall of steel sheet-pile cofferdam, the well ellbeam formula lower floor precast concrete inner support being positioned at steel pile casting position is completely covered with the precast concrete plank of the bottom template as cushion cap.
The beneficial effects of the utility model are: lower floor's precast concrete inner support entirety can be transferred before drawing water, when setting steel sheet pile, purlin Collaborative Control steel sheet pile verticality can be enclosed with upper strata planar positioning structure and upper strata, solve and adopt common individual layer guiding construction technology often to occur the phenomenons such as steel sheet pile inserted to play off normal, inclination; Precast concrete inner support is laid the bed die that precast concrete plank can be used as bearing platform construction, precast concrete inner support and cushion cap bed die are united two into one, do not need to design separately bearing platform construction template, and conflicting of solving that bearing platform construction template position lays with cofferdam inner support; Precast concrete inner support integral rigidity can be utilized in addition large, good stability, effectively can control the distortion of steel sheet pile when drawing water construction, ensureing the resistance to overturning of steel sheet-pile cofferdam.The utility model effectively can control the vertical precision of steel sheet pile, improves operating efficiency simultaneously, has saved cost.
