Steel boxed cofferdam and positioning construction method
The invention relates to the technical field of bridge building, in particular to a steel boxed cofferdam and a positioning construction method. The steel boxed cofferdam comprises a boxed cofferdam bottom plate, boxed cofferdam side plates, guide tubes and limiting brackets; the boxed cofferdam side plates are arranged to the edges of the boxed cofferdam bottom plate vertically, and the boxed cofferdam side plates and the boxed cofferdam bottom plate jointly encircle a box body with the top open; mounting holes used for allowing pile foundation steel casings to be penetratingly arranged are arranged in the box cofferdam bottom plate; each limiting bracket is arranged at the edge of the corresponding mounting hole; each guide tube is arranged on the corresponding pile foundation steel casing, clings to the corresponding boxed cofferdam side plate and is used for guiding the box body to sink axially along the pile foundation steel casings. The steel boxed cofferdam can realize accurate positioning by the aid of itself and the pile position and has the advantages of being simple and convenient to construct, beneficial to control and high in precision.
