Combined cofferdam suitable for offshore large-size bearing platform construction

Abstract

The invention discloses a combined cofferdam suitable for offshore large-size bearing platform construction, relates to the field of constructional engineering, and aims to solve the problems that under the conditions of super-thick silt layer geology and large-size bearing platform construction, an existing constructed cofferdam is too high in material consumption, high in cost, difficult in sinking, prone to deviation, high in measurement and positioning difficulty and the like. The combined cofferdam suitable for offshore large-size bearing platform construction comprises a plurality of main steel pipes, a plurality of connecting lock catches and a plurality of pieces of profile steel; a plurality of bearing platforms are arranged in multiple columns; each column of bearing platforms is formed by vertically arranging the plurality of bearing platforms side by side; a circle of profile steel is welded to the periphery of each bearing platform; the multiple main steel pipes are arranged in rows; every two adjacent main steel pipes are connected through a connecting lock catch; the rows of main steel pipes surround the peripheries of the multiple columns of bearing platforms and are welded to the profile steel; and every two adjacent columns of bearing platforms are arranged in a staggered mode and are connected through one row of main steel pipes. The combined cofferdam is used for fixing the bearing platforms.

Description

Technical field [0001] The present invention relates to the field of construction engineering, in particular to a combination of a large number of large-volume gauges for sea. Background technique [0002] During the construction of the sea, the steel plate pile cofferdam is usually used, and the Shuangshuang Steel Fujun is usually used. Because the typhoon high-risk region and geological laminar plastic silty clay clay, the engineering nature is poor, especially for geological exploration Clearly, the construction of large volume concrete is highly safe and secure, but the construction flexibility is poor, transportation, assembly and demolition, etc., the safety risk is very large. [0003] In the face of the above situation, some engineering teams use Shuangwu Subai Construction Jobs to avoid quality accidents and ensure safety. However, this operation is not applicable in such operations in the case of ultra-thick silt layers, and the reason is that the silt layer thickness i...
