With the progress of the society, the construction technology has been developed rapidly. The rationality of construction technology has a very important iimpact on the completion of construction schedule and the economic rationality of the scheme. Canal is an indispensable element of transportation network in modern society. Compared with highway construction, more attention should be paid by all related organizations to the the safety requirements for water operation on the canal project. Taking the comprehensive renovation project of the outer ring canal as an example, an omnibearing research on engineering was made from the introduction of the initial working conditions of the project, the calculation of construction resources, the arrangement of construction schedule and the guarantee of construction,which can play a guiding role in the smooth construction of the project. The research findings can provide a feasible reference for the construction management of the same type of canals.
