Study Of Hole-pile Method Construction Technology Using In Subway Line No.1 Of Shenyang At Shenyang Station

On the basis of analyzing hole-pile construction principle, this thesis has expounded the facts that isolated station of the single span and single column—pair span station of side type step construction procedure, also including the key technologies of construction, the difficult points of construction and corresponding countermeasures.Standing for the example with Subway Line No. 1 of Shenyang, this thesis has described the hole-pile method in Shenyang station of subway construction. Supporting in excavating,piling on side of cave,roof beam on piles,manual excavating,steel pipe pile,top arch excavating and support,excavating under station and support as well as other auxiliary furniture in construction are deeply anglicized .All of these have offered experience and beneficial reference for similar project.Utilize supervision survey to obtain procedure information data to guide construction. it is an indispensable part in hole-pile method. For example with Subway Line No. 1 of Shenyang, this thesis has studied that how to take advantage survey data to guide the construction. This has offered a feasible method for informationization in construction procedure . Proceed from development trend of the informationization of subway construction, constructor should set up a GIS system , which monitoring and conducting construction procedure to assist auxiliary furniture, this system's designation including overall design and detail function design. Considering the system development and GIS platform to select the function design.
