Construction Technology of Combined Tower Crane Foundation in Deep Foundation Pit
With the development of society and the improvement of construction technology,in order to fully utilize land resources,coupled with the increasing complexity of construction projects and surrounding environments,people are beginning to design more and more high-rise buildings and expand space underground.The depth and scale of basements are increasing,and the foundation pit enclosure structure is becoming more and more complex.Especially in deep foundation pit engineering,the forms of support are complex and diverse.In modern large-scale deep foundation pit engineering,the steel lattice column composite foundation is increasingly widely used as a construction tower crane foundation in construction projects.In the construction process of deep foundation pits,creating conditions to ensure the early use of tower cranes is of great significance for reducing deformation of the pit enclosure and improving the efficiency of basement construction.Especially in deep and large foundation pits under weak geological conditions,the use of a lattice column combined tower crane foundation(i.e.steel columns and abutments)can meet the structural stability and construction lifting requirements of tower crane equipment.This paper discusses the key points of construction technology control for this combined foundation.
