Description
Technical field
The invention belongs to the water-stopping structure in man-made island steel cylinder cofferdam in the waters, the water-stopping structure in the concrete steel cylinder cofferdam, worker island that relates to a kind of especially suitable narrow and small irregular steel conformational space sealing.
Background technology
The cofferdam is to go along with sb. to guard him hydraulic structure construction foundation pit and construction plant, makes it avoid that current and wave effect become construction at dry land and the temporary water dash building built.Steel sheet-pile cofferdam is island, the cofferdam job practices of the most often using at present, and the employing steel sheet pile is repeatedly located to set and reached stagnant water effect as the one of which.Steel sheet pile is a kind of shaped steel that has fore shaft, and there are straight plate shape, flute profile and Z-shaped etc. in its cross section, and different size dimensions and interlocking form are arranged.Common Ademilson formula, the clarke Wan Nashi etc. of drawing.Steel sheet-pile cofferdam has the intensity height, squeezes into hard soil layer easily; Can in deep water, construct, add the characteristics that bearing diagonal becomes an inclosure in case of necessity.Its water resistance is good; Can form the cofferdam of various profiles on demand, and can be repeatedly used.Steel pipe pile commonly used is to make structure body cofferdam in hydraulic architecture.It is to be made up of many interconnected monomers, and each monomer is made up of many steel sheet piles again, tamps with native stone in the middle of the monomer.The scope that go along with sb. to guard him in the cofferdam is very big, can not use to support and support the weir wall, so each monomer can both be resisted the drawing crack of toppling, sliding and preventing the interlocking place alone.Commonly used have forms such as circle and next door shape.
The construction of existing steel sheet-pile cofferdam is comparatively loaded down with trivial details, and structure is also comparatively complicated, and the accumulated error that steel pipe pile is repeatedly located usually can be brought various quality problems.
Summary of the invention
The invention provides the water-stopping structure in the man-made island steel cylinder cofferdam of a kind of reasonable in design, form of construction work shortcut and simple; Its adopt tongue-and-groove and gusset to be connected and through being provided with of mould bag form stable firmly, the good structure of stagnant water effect, have the advantage of light-duty, high strength and rapid construction simultaneously.This water-stopping structure has high compact property and high-durability, can effectively reduce the difficulty of construction and the amount of labour, improves efficiency of construction and reduces construction cost.
The technical scheme that the present invention adopted is following:
The water-stopping structure in a kind of man-made island steel cylinder cofferdam; It is characterized in that said water-stopping structure comprises the steel pipe pile of steel cylindrical structure and the steel cylinder cofferdam that secondary lattice curved plate is combined to form, tongue-and-groove and the gusset that cooperatively interacts is set respectively between said steel pipe pile outer wall and secondary lattice curved plate;
Said gusset is installed in the said tongue-and-groove, also is filled with the mould bag in this tongue-and-groove, is filled with the sealing composite material in this mould bag, and said mould bag is squeezed in gusset and forms the sealing hermetically-sealed construction in the said tongue-and-groove opening.
In the specific embodiment, said steel pipe pile is provided with at interval, connects between the adjacent steel pipe pile two groups of secondary lattice curved plates are set.
In one embodiment, the dual-side of said secondary lattice curved plate is provided with the gusset of width greater than secondary lattice curved plate thickness, and said gusset is the spiral-lock setting in tongue-and-groove; The mould bag is arranged in the space between gusset and the steel pipe pile outer wall along tongue-and-groove.
In another embodiment, the outer wall of said tongue-and-groove fixedly installs sheet rubber in the inside and outside both sides of secondary lattice curved plate, and said sheet rubber extends the side end face of the secondary lattice curved plate of covering outside tongue-and-groove, backfill sandstone in the cavity in the said secondary lattice curved plate.
In the embodiment, said tongue-and-groove outside welding reinforcing rib distributes between said reinforcing rib and said tongue-and-groove outer wall and steel pipe pile outer wall and welds again.
The water-stopping structure in this man-made island steel cylinder cofferdam adopts the steel pipe pile of steel cylindrical structure and the mode of secondary lattice curved plate combination to form steel cylinder cofferdam; The steel pipe pile of steel cylindrical structure is provided with at interval; Form coffered foundation, the space between the steel pipe pile is by the block of secondary lattice curved plate.Be provided with two secondary lattice curved plates between the adjacent steel pipe pile, secondary lattice curved plate can form the zone between the adjacent steel pile tube space of a sealing.Between secondary lattice curved plate and the steel pipe pile through gusset with tongue-and-groove realization assemble and be connected; The dual-side welding of secondary lattice curved plate is provided with the gusset of width greater than secondary lattice curved plate thickness; Tongue-and-groove is to have the opening that is equivalent to secondary lattice curved plate thickness, has the containing cavity that is equivalent to the gusset width in it.The concrete middle tenon groove of using can adopt two L shaped steel plate welding to form, and distributed and arranged T type reinforcement longitudinally gusset is to improve the intensity of secondary lattice curved plate on the secondary lattice curved plate.
Realize the vertical heavy assembling of shaking between the gusset of secondary lattice curved plate and the tongue-and-groove of steel cylinder stake, the assembling back is the sealing ability between raising tongue-and-groove and gusset, and the present invention is employed in the mode that the tongue-and-groove inherence is filled with the mould bag and realizes.The mould bag has a flexible macromolecule tubular bag, between the outer tube wall of its gusset and steel pipe pile in tongue-and-groove, can fill in the sealing composite material in this mould bag, and from inside to outside pressing rib and tongue-and-groove opening part form sealing.Said sealing composite material can adopt mixes swell soil plastic cement mortar; The cement mortar that together forms with sand after the hardening of cement has certain intensity; And swell soil has expansion, can suppress the contraction in the cement hydrating hardening process, and stagnant water effect is good.In addition; Outer wall at tongue-and-groove fixedly installs sheet rubber in the inside and outside both sides of secondary lattice curved plate; One side of two sheet rubbers is fixed with the other steel plate wall of tongue-and-groove opening respectively; Stagnant water effect can further be improved after filling sandstone in the cavity between secondary lattice curved plate and steel cylinder stake in the fit inside and outside side end face of secondary lattice curved plate of the opposite side of two sheet rubbers.
Beneficial effect of the present invention is; Water-stopping structure reasonable in design, the form of construction work shortcut and simple in this man-made island steel cylinder cofferdam; Its adopt tongue-and-groove and gusset to be connected and through being provided with of mould bag form stable firmly, the good structure of stagnant water effect, have the advantage of light-duty, high strength and rapid construction simultaneously.This water-stopping structure has high compact property and high-durability, can effectively reduce the difficulty of construction and the amount of labour, improves efficiency of construction and reduces construction cost.
