Research on Water Conservancy Project Construction and Operation Management based on Cost Management

With the development and progress of economy society, management level my country’s construction projects has also been greatly improved, especially in water conservancy projects, cost process made significant progress; industry is order to improve market enterprises. Competitiveness, increase share company, it necessary company an all-round way, maximize economic benefits company.In efficiency operation this study conducts a theoretical analysis project management, taking reinforcement treatment expansion joints culverts main canal first phase diversion supply as research case, analyzes project. This paper comprehensive investigation, proposes repair plan using chemical bonding with external TPO waterstop PTN petroleum asphalt polyurethane joint material, makes detailed investment estimate for implementation. The results show that externally attached materials can meet needs design strengthening culvert. total static engineering, mechanical electrical equipment installation temporary independent costs basic reserve 4,585,800 yuan, which underdrain 3,594,600 line expectations, indicating design. feasible.
