Abstract

The invention discloses a double-wall steel cofferdam construction multifunctional platform which adopts the scheme that a bottom isolation cabin is arranged at the bottom of the inner side of the steel cofferdam; a plurality rows of uprights vertical to the upper surface of the bottom isolation cabin are arranged on the bottom isolation cabin; a horizontal track beam is mounted at the tops of each row of the uprights; a steel rail parallel to each track beam is mounted at the top of each track beam; a moving joist barrow is arranged on each steel rail; a plurality of horizontal bearing beams are arranged on the inner wall of the steel cofferdam; drilling platform main beams are erected at the tops of the bearing beams, and are erected at the tops of the track beams; a plurality of vertical steel casings are mounted on the drilling platform main beams. According to the invention, the uprights and track beams fixed at the tops of the uprights are arranged inside the steel cofferdam, and a mud suction platform and a drilling platform can be erected on the track beams in sequence, so that mud suction platform dismantling time can be shortened, and drilling platform mounting time can be reduced; besides, the use quantity of steel materials can be reduced and manufacturing cost is reduced as the mud suction platform and the drilling platform can be combined.

Description

technical field [0001] The invention relates to a cofferdam, in particular to a double-wall steel cofferdam construction multifunctional platform and a construction method thereof. Background technique [0002] Cofferdam refers to the temporary enclosure structure built for the construction of permanent water conservancy facilities in the construction of water conservancy projects. Its function is to prevent water and soil from entering the construction site of the building, so as to drain water in the cofferdam, excavate the foundation pit, and build the building. Generally, it is mainly used in hydraulic construction. Except as a part of formal buildings, cofferdams are generally removed after use. When the pile foundation construction in water adopts the first cofferdam and then the platform construction method, it is necessary to set up a mud suction platform on the steel cofferdam, and the mud suction will make the cofferdam sink to the design elevation. After the cof...
