Description

Temporary water-passing structure for in-service channel transformation Technical Field The utility model relates to the technical field of channel transformation, in particular to an in-service channel transformation temporary water-through structure. Background When the channel is transformed and constructed, steel sheet piles, earth-rock cofferdams and the like are generally adopted to cut off the upstream and downstream of a construction area, dry construction conditions are created, channel dredging, foundation treatment, lining repair and other transformation operations are facilitated, and the technology has the advantages of mature construction method and relatively stable and reliable structure under the working conditions of complete cutoff and long-time water stopping permission through long-term engineering practice inspection. However, for in-service channels that are tasked with urban life, production and ecological water supply along the line, the traditional method of construction of cut-off cannot solve the contradiction between the rigid requirement of continuous water supply during construction period and the dry work environment. Because the in-service channel can not cut off water for a long time, and all construction contents of channel transformation can not be completed in a short time in an allowed water cut-off period. Therefore, a temporary water-through structure for in-service channel transformation needs to be provided, and compared with the prior art, normal water-through of channels is guaranteed while creating dry construction conditions.
