Steel sheet pile

Mar 21,2017


    Steel sheet pile cofferdam is one of the most commonly used sheet pile cofferdam. Steel sheet pile with a steel lock, the section is provided with a straight groove shape, and Z shape, there are a variety of sizes and interlocking form. There is a common type of Larson, Lackawanna type etc..

    The utility model has the advantages of high strength, easy to break into the hard soil layer; construction in deep water, if necessary with the inclined support into a cage. The utility model has the advantages of good waterproof performance, and can form various shapes of the cofferdam according to requirements, and can be used repeatedly. It is widely used in the construction of cofferdam in the bridge construction. Column foundation, pile foundation and cofferdam of open cut foundation. The use of single wall enclosed cofferdam, cofferdam in the vertical and horizontal support, if necessary with the inclined support into a cage. Such as the Yangtze River Bridge in Nanjing, China, the foundation of the column, the use of circular steel sheet pile cofferdam, the diameter of 21.9 meters, steel sheet pile length of 36 meters, there are various sizes and interlocking forms. To reach the bottom of underwater concrete strength requirements, pile cap and pier construction pumping, pumping design depth of 20 meters.

    In hydraulic engineering, the general construction area is large, it is often used to make the structure of the cofferdam. It is a single connected to each other by many, each monomer is composed of many steel sheet pile, single middle filled with soil. The enclosure of the cofferdam is so large that it can not be used to support the wall of the weir, so each monomer can resist overturning, sliding and preventing the crack of the interlock. Commonly used in the form of circular and adjacent.
