Abstract

The invention relates to an attached type steel jacket box cofferdam, and relates to the technical field of bridge construction. The attached type steel jacket box cofferdam comprises a steel jacket box body connected with an existing structure object, a connector device is arranged between the existing structure object and the steel jacket box body and comprises a connecting guide device fixedlyconnected with the steel jacket box body and an insertion plate device moving in the connecting guide device; and a gap between the connecting guide device and the existing structure object is filledwith the insertion plate device and forms a filling space. According to a semi-encircling steel jacket box structure, the problem about construction of the steel jacket box cofferdam is solved throughthe connector device.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an abutting type steel casing cofferdam. Background technique [0002] Prior Art Steel box cofferdam is a common technical measure for the construction of underwater structures. The common structural forms are square, circular or other closed structures. However, when the underwater structure is close to the existing structure, the gap between the two When the space size is insufficient and the steel box cannot form a closed structure, the construction of the steel box cofferdam cannot be completed according to the self-closed structure. [0003] Now the public document with the publication number CN106638639A discloses a steel casing cofferdam, which comprises a cofferdam left side plate and a cofferdam right side plate, and the cofferdam left side plate and the cofferdam right side plate are connected by tenon-type snapping, The left side panel of the cofferdam inc...
