Description

Bridge pier cofferdam device for bridge construction Technical Field The utility model relates to the technical field of bridge construction devices, in particular to a bridge pier cofferdam device for bridge construction. Background In bridge construction, when bridge piers and platform foundations are located below the surface water level, a cofferdam is needed to be built, a water area with a certain range is surrounded by the cofferdam, water is blocked outside the cofferdam, and a bridge pier construction area and surrounding water are isolated, so that a construction area without water level is formed inside the cofferdam, and smooth construction or repair of the bridge pier foundations is ensured. At present, a cofferdam device is formed by splicing a plurality of water retaining steel plates to form a fence, and the water retaining steel plates are combined by buckling two adjacent baffle plates when being spliced. But after a plurality of manger plate steel plates lock joint installation, can have the clearance when two adjacent manger plate steel plates lock joint, lead to the phenomenon that appears the seepage between two adjacent manger plate steel plates in the device use easily to influence cofferdam effect. Disclosure of utility model Based on this, it is necessary to provide a bridge pier cofferdam device for bridge construction, which is easy to cause leakage between two adjacent water retaining steel plates in the using process of the device because a gap exists when the two adjacent water retaining steel plates are fastened, thereby affecting the cofferdam effect.
