Embodiment 1

[0027] Such as figure 1 and figure 2 A cofferdam pile hanging and flood control method for pier construction is shown, using a double-layer cofferdam: (a) floating the cofferdam to the design water area for positioning; (b) using a floating crane to place the cofferdam N positioning steel casings are inserted inside, and N positioning steel casings are evenly arranged along the inner wall of the cofferdam, and N is an integer greater than or equal to 4; (c) Open holes facing the cofferdam on each positioning steel casing , weld the reinforcement plate in the hole, and install the hanging pile corbel on the reinforcement plate; (d) Slowly pour water into the side plate compartment of the double-layer structure cofferdam, so that the cofferdam will sink by itself until the inner bracket of the cofferdam and each hanging The pile corbels contact and 30% of the cofferdam's self-weight is supported by the hanging pile corbels to complete the positioning of the cofferdam hanging p...

Abstract

The invention discloses a method for cofferdam pile suspension of pier construction and flood protection. The height of a cofferdam can be increased under the conditions that a locating steel protective cylinder is static, so that a cofferdam can safely pass the flood season, consumed material and cost for manufacturing the cofferdam are greatly reduced, the self weight and draft are reduced, requirements for the water area depth are lowered, and engineering construction has wider applied range. According to the method, the material consumption and engineering cost are greatly reduced while the cofferdam can pass the flood season safely.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a cofferdam pile hanging and flood control method for bridge pier construction. 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. Cofferdams can be divided into earth-rock cofferdams, grass-soil cofferdams, wooden sheet pile cofferdams, wooden cage cofferdams, steel sheet pile cofferdams, locking pipe pile cofferdams, reinforced concrete or prestressed concrete sheet pile cofferdams, Concrete cofferdams, e...
