Spliced chamber cofferdam for repair of canal lining projects
The invention discloses a spliced chamber cofferdam for repair of canal lining projects. The cofferdam is in an I shape can comprises top end cofferdams and a middle cofferdam, wherein the top end cofferdams are matched with the cross section of a canal in shapes and located at the two ends of the upstream and the downstream, and the middle cofferdam is arranged between the two top end cofferdams and located in the center of the canal. The cofferdams are formed by splicing a plurality of chamber bodies in the direction of water flow, every two chamber bodies connected in the direction of the water flow are communicated with each other, hydraulic doors used for opening or closing a water flow channel is arranged on the chamber bodies located at the top ends, the adjacent chamber bodies are connected with each other through lock catches and are provided with waterstops, bottom plates of the chamber bodies which are located at the center of the canal and are in contact with the bottom of the cannel can be disassembled, and a pedestrian path leading to the bottom of the canal is arranged at the tops of the chamber bodies of the middle cofferdam. The spliced chamber cofferdam for canal lining repair does not need a pile foundation, is stable without a root, and cannot damage canal lining concrete and water-stopping materials under the canal lining concrete. The spliced chamber cofferdam is convenient to assemble, disassemble, store, transport and construct, good in safety, capable of being repeatedly utilized, and particularly suitable for repair and replacement of the canal lining concrete of large water conveyance projects and the water-stopping materials under the canal lining concrete.
