Hooping type steel sheet pile cofferdam platform and integrated construction method depending on cofferdam platform

Abstract

The invention relates to a hooping type steel sheet pile cofferdam platform and an integrated construction method depending on the cofferdam platform. Fillers are filled in the inner space of a cofferdam; at least two circles of steel tendons are arranged around the periphery of the cofferdam; one end of each steel tendon is fixed on an anchor bearing plate at the fixed end through an anchor device at the fixed end, and the other end of each steel tendon is fixed on an anchor bearing plate at the stretching end through an anchor device at the stretching end; and the steel tendons also pass through a positioning ring which is fixed at the convex part of the periphery of a steel sheet pile. By additionally providing facilities and measures for reinforcing the steel sheet pile cofferdam, the construction of the underwater pile foundation can be finished only depending on the steel sheet pile cofferdam required for the platform construction under the condition that a waterborne overhead pile drilling platform does not need to be arranged, and the integrated construction of the platform can be finished only depending on the steel sheet pile cofferdam arranged in the construction of the underwater pile foundation without additionally arranging a steel sheet pile cofferdam. The method of the invention has the advantages of saving the overall cost of the engineering, shortening the construction period, reducing the unsafe factors in construction, saving the energy, reducing the emission, and the like. The invention can be widely applied to construction of engineering, such as underwater bridges, wharfs, and the like.

Description

technical field [0001] The invention relates to a construction platform and construction method for underwater piles and caps, in particular to a hoop-type steel sheet pile cofferdam platform and an integrated construction method relying on the cofferdam platform. Background technique [0002] For the construction of underwater pile foundations of bridges, wharves and other engineering structures, the current traditional method is generally to set up an overhead drilling platform on the water and rely on the overhead drilling platform for construction. After the construction of the pile foundation is completed, the overhead drilling must be removed first. pile platform, and then the construction of the cap can be started; while the cap is often constructed by setting a steel sheet pile cofferdam, but the steel sheet pile cofferdam is limited to the construction of the substructure such as the cap or pier body; because the water pile The construction supporting facilities of...
