Abstract

The invention discloses a cofferdam device for hydraulic construction. The cofferdam device comprises a first outer coaming, a second inner coaming and a clamping groove, wherein a second outer coaming is mounted below the first outer coaming; a stiffener is mounted above the left side of the first outer coaming; an auxiliary outer coaming is mounted at the end, away from the first outer coaming,of the stiffener; connecting rods are arranged on the left side of the first outer coaming; a first inner coaming is mounted on the left sides of the connecting rods; the second inner coaming is mounted below the first inner coaming; screw holes are formed in the middle of the first inner coaming; steel wire ropes are fixed below the first inner coaming; reinforcing nails are fixed below the steelwire ropes; a connecting groove is formed in the right side of the first outer coaming; a connecting block is mounted in the connecting groove. The cofferdam device for hydraulic construction is provided with a clamp plate, so that impact force of water flow on the outer coamings can be reduced, the service life of a cofferdam is prolonged, and the surface of the clamp plate is of a bulge structure.

Description

technical field [0001] The invention relates to the technical field of water conservancy construction cofferdams, in particular to a water conservancy construction cofferdam device. 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. , building buildings, generally mainly used in hydraulic construction, except as a part of the formal building, the cofferdam is generally removed after use, and the height of the cofferdam is higher than the highest water level that may occur during the construction period, so the cofferdam Stability and water resistance, as well as the convenience of disassembly and assembly are of great significance to the cofferdam. [0003] The structure of the cofferdam on the market is complex, the installation and disassembly are very cumbersome, and the practicability is low. Secondly, the cofferdam can...
