Construction Technology Of Underwater Pile Foundation And Pile Caps Of Shuiyang River Bridge

As the rapid development of infrastructure construction in the area of railway engineering and highway engineering, more and more bridge engineering technology are used in crossing the river and other obstacles. Many bridges must be built in deep water foundation. Deep water foundation becomes the key to the construction of Bridges because security risk is high, the construction is difficult and the construction period is long and so on. Research on bridge deep water foundation construction technology of our country’s railway construction, especially the bridge construction has a great practical significance.The construction technology of the water pile caps of the bridge and Lassen IV steel sheet pile cofferdam in construction of Shuiyang River bridge is systematically explained in thesis,which is based on the research of 480 # and 481 # bridge pier foundation construction. The design and installation of steel pipe pile, the construction process of bearing platform and temperature control technology of the mass concrete construction is expounded in thesis. Second, The technology of Lassen IV steel sheet pile cofferdam hoisting, earthwork excavation and installing internal support construction process is particularly introduced in thesis. Next, The process of the excavation steel sheet pile cofferdam system in different working conditions is checked. Thesis also optimized for mass concrete construction technology, and through temperature monitoring, the construction rationality is verified, provide experience for future similar projects.
