Steel Sheet Pile Cofferdam Construction Technology In Winter

Steel sheet pile cofferdam is the most commonly used as a sheet pile cofferdam. With a locking steel sheet pile is a steel, the cross section of the candy bar-shaped, Z-shaped trough, and so on, a variety of sizes and chain form. Common are Larson-type, type, and so Lackawanna. Its advantages:high strength, easy to break into the hard soil; construction in deep water, if necessary, add a ramp around the cage support. Waterproof performance; to form various shapes as needed cofferdam, and can be repeatedly used, therefore, it is widely used. Steel sheet pile cofferdam at home and abroad is very mature technology, but the steel sheet pile cofferdam construction technology in winter still in its infancy, there is no formation reported in the literature.Harbin Songpu Bridge tower platform based in the Songhua river water, to ensure the scheduled opening of cap construction to be completed in the winter, the cap at the depth of about 5 meters,1 meter layer of frozen river in winter the water and back steel sheet pile cofferdam Concrete Placement in the successful application of the program, based on time and cap the tower, completed in full bridge won the planes on schedule. With Harbin Matsuura Bridge tower foundation construction master instance, the water in winter to cold steel sheet pile cofferdam and construction of underwater concrete back to study.
