Description
Technical field
The utility model belongs to technical field of bridge engineering, is specifically related to a kind of bridge pier cofferdam equipment integrating and construction method thereof.
Background technology
Cofferdam refers in hydraulic engineering construction, for building permanent water conservancy projects, and the provisional space enclosing structure of building.Its effect be prevent water and soil from entering building build position so that at cofferdam internal drainage, excavation pit, builds building.Generally be mainly used in hydraulic architecture, except the part as formal building, cofferdam is generally removed after being finished.Cofferdam height is higher than the peak level that may occur in the construction period.
Steel sheet-pile cofferdam is the most frequently used a kind of sheet pile cofferdam.Steel sheet pile is a kind of shaped steel with fore shaft, and there are straight plate shape, flute profile and Z-shaped etc. in its cross section, has full range of sizes and interlocking form.Common are and draw Ademilson formula, clarke Wan Nashi etc.Its advantage is: intensity is high, easily squeezes into hard soil layer; Can at dark subaqueous work, water resistance is good; The cofferdam of various profile can be formed on demand, and can repeatedly use, therefore, it of many uses.The cofferdam on open caisson top is usually used in, the cofferdam etc. of cylinder pile foundation, pile foundation and open cut foundation in bridge construction.Have vertical cross binding in these closed cofferdam of many employings single wall, cofferdam, adding bearing diagonal if desired becomes an inclosure.As the cylinder pile foundation of Nanjing of China the Changjiang river bridge, once used steel sheet pile circular cofferdam, its diameter 21.9 meters, long 36 meters of steel sheet pile, after underwater concrete back cover reaches requirement of strength, draw water and build cushion cap and pier shaft, projected depth of drawing water reaches 20 meters.In hydraulic architecture, general construction area is very large, then conventional to make structure body cofferdam.It is be made up of many monomers be connected to each other, and each monomer is made up of many steel sheet piles again, and monomer centre soil tamps.The scope that cofferdam is gone along with sb. to guard him is very large, and can not support weir wall with supporting, therefore each monomer can resist alone the drawing crack toppling, slide and prevent interlocking place.Conventional has the form such as circle and next door shape.
Steel sheet-pile cofferdam is applied more in China's construction, but its construction is extensive, and cost haggles over height, and also tamp with soil between steel sheet pile composition, such duration is longer, needs water pump ceaselessly to draw water in inside, cofferdam, and such operation is very trouble.
Secondly, if a patent No. is ZL201220322013.7, the applying date 2012. 07 .05, a kind of circular cofferdam is disclosed in the Chinese utility model patent of notification number CN202706045U, comprise the one group of steel sheet pile and cofferdam substrate that are enclosed in cushion cap periphery, it is characterized in that: described steel sheet pile is arranged to tubular cofferdam wall along cushion cap circumferential annular, the root of described steel sheet pile extends to below cofferdam substrate, and the top of steel sheet pile is higher than cushion cap; Be close to this group steel sheet pile inside wall be provided with cofferdam, described in enclose purlin along wall border, cofferdam from top to bottom successively interval be circular layout; Also be provided with the inner support be fixedly connected with cofferdam inwall in the disk at described first cofferdam and the 3rd cofferdam, road place respectively, described inner support is the rectangular frame that encloses of steel pipe and itself and cofferdam substrate are arranged in parallel.
And for example a patent No. is ZL201120427362.0, the applying date 2011. 11 .02, a kind of steel sheet pile cofferdam structure is disclosed in the Chinese utility model patent of notification number CN202359565U, be made up of steel sheet pile and weir, cofferdam body, it is characterized in that: described steel sheet pile is single, be arranged at body side near water, weir, cofferdam; Weir, described cofferdam body is filled by rock structure and forms.
Both cofferdam structures above-mentioned generally apply in construction at present, and its construction is extensive, and the time is long, and a large amount of bamboo pole is buried in inserting in operation waters of having; And a large amount of clothes is hung up above, cloth fixed point on bamboo pole with resistance effect is many, and operation is slow; After operation completes, the recovery for bamboo pole and cloth too bothers, especially when cofferdam workload is large.
Summary of the invention
