Construction Organization Design And Analysis Of Chang-Ping Expressway Reconstruction And Extension Project

Construction has experienced twenty-eight years from Shanghai-Jiading Expresswayopened to traffic so far in China. With the continuous development of the national economy,a number of expressway capacity can not meet the demand, in order to speed up the transportspeed with minimal damage to the environment, reconstruction and extension on the existingexpressway is imperative. Chang-Ping expressway is the first one in Jilin province and it hasbeen included in the renovation and expansion plan. There is a certain difficulty to theconstruction organization due to the geographical environment in our province and materialsupply capacity is different from other regions. According to the geographical situation androad network conditions of Jilin province and surrounding provinces, constructionorganization analysis of reconstruction and extension project of Chang-Ping expressway iscarried out in this paper. After analyzing and comparing the various constructionorganization features of reconstruction and extension project, the construction organization isproposed which is fit for Chang-Ping expressway reconstruction and extension project. Inorder to reduce the temporary works and temporary land used, the roadbed widened willused as longitudinal construction road and construction organization Change the extension offor high-speed reconstruction and existing toll stations, service areas as construction plant.An objective analysis of the Chang-Ping expressway reconstruction and extensionproject and other projects at the same time is carried out. The procurement of materials andtransport is reasonably arranged. The traffic organization is planed using the existing roadnetwork during the renovation and expansion to make the transportation unimpeded duringthe construction. In the organizational arrangements of the sub-construction works, theChang-Ping expressway bilateral widening and the Liu house unilateral widening combinedwith the actual situation, in accordance with the construction characteristics of thesub-project, construction organization plan semi-enclosed and segmented closed combined isproposed. It is a combination of an effective solution to ensure the passage and complete theconstruction, and provides strong technical support for Chang-Ping expresswayreconstruction and extension project. Through the construction organization design ofrenovation and expansion project, organization of the construction of the expresswayconstruction is in-depth analyzed. The construction organization design for the construction of guiding significance is stated in details close combined with construction design andanalysis, provides a basis for the promotion of design and construction combined.
