Lijiang Road Underpass Tunnel Construction Organization

China is a vast territory and mountainous country, with the social development and national needs, construction of mountain-road has became a urgent and arduous task. In many mountain roads, tunnel can reduce circumambulation and shorten the route mileage, reduce the maintenance and transport costs, coordinate with local environment and maintain natural landscape; In the city, tunnel can provide convenience to people, increase flow capacity, and improve traffic safety and reliability.Construction of the tunnel is a complex project work, a good construction organization is a strong guarantee and solid foundation to ensure the smooth progress of the project and completed on schedule. Construction organization design is based on a single object for preparation, with a strong technical and comprehensive, Need staff have enough construction theory and some practical experience. For a proposed project, If the construction organization design prepared reasonably, reflected the objective reality accurately and carried out seriously during the construction process, which can guarantee the order of the proposed project going smoothly, getting good, fast, effective and safe province, achieving Technical and economic benefits under certain resource conditions, and running up to goal of construction and economic benefits.Construction organization is a systems engineering technology including organizational management and construction management. This paper from project overview, construction deployment, resource guarantee, technical scheme ,technical measures and other sides to research and explore the construction organization. And have made a detailed analysis shows about schedule,workforce planning,material planning,financial planning, equipment and management system, engineering major and difficult and countermeasures, major construction program, project quality assurance measures, construction measures during winter and the rainy season , site security,civilized construction and environmental protection measures; has also improved the dewatering process and used the new technology which is steel well construction technology.
