Abstract

The invention discloses bridge pier-cofferdam integrated equipment. The bridge pier-cofferdam integrated equipment is characterized by comprising a cofferdam, wherein the cofferdam is formed by mounting and connecting a plurality of water separating devices and water pumping devices having the same arrangement number at intervals. The bridge pier-cofferdam integrated equipment has the following advantages: (1) the equipment is small in size and number and is convenient to mount and transport; (2) in the mounting and application process, the cofferdam can be quickly formed through quick assembly and the recovery is fast, so that the automation degree is high and the whole construction process time is greatly shortened; and (3) the equipment can efficiently and conveniently divide and block a water area; and the device recovering process becomes convenient.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a bridge cofferdam integrated device and a construction method thereof. 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. The height of the cofferdam is higher than the highest water level that may occur during the construction period. [0003] Sheet pile cofferdam is the most commonly used type of sheet pile cofferdam. Steel sheet pile is a kind of section steel with lock. Its cross...
