Abstract
The invention provides a design method for a large deep foundation pit of a super high-rise building, which comprises the following steps of: dividing the large deep foundation pit of the super high-rise building into a tower community foundation pit and a podium community foundation pit; carrying out construction on envelope enclosures of a pile foundation and the foundation pit of the tower community foundation pit; carrying out down-top construction on the tower community foundation pit; carrying out construction on envelope enclosures of a pile foundation and the foundation pit of the podium community foundation pit; and after building a tower structure to finish a top plate of a basement, carrying out top-down construction on the podium community foundation pit. According to the design method for the large deep foundation pit of the super high-rise building which is provided by the invention, the construction period of the super high-rise building is accelerated by using coordinative designed construction of the tower community foundation pit and the podium community foundation pit, so that the whole construction period is positioned at an optimal time value; and meanwhile, the problem of insufficient construction site is solved and the influence of foundation pit construction on a surrounding environment is reduced.
Description
Technical field
The present invention relates to the underground construction design field, relate in particular to a kind of method for designing of super highrise building deep big foundation pit.
Background technology
Along with the continuous development of urban construction, various types of underground constructions, deep-foundation pit engineering are more and more, and the construction method of deep foundation ditch of efficient, economy, energy-saving and environmental protection seems particularly important.At present, traditional construction method of deep foundation ditch is open type construction, and its method is to go along with sb. to guard him the back vertical cut or excavate with putting the slope greatly with supporting and protection structure.Dig to design elevation after-pouring steel bar concrete base plate, the basement structure of from bottom to top successively constructing is again treated to carry out the superstructure construction again after underground structure is accomplished, and this job practices is along practice construction.Opposite with suitable practice construction is contrary sequence method (Top-down method) construction; After space enclosing structure and engineering piles and stand column pile completion; Directly the construction underground structure top board; And then successively carry out the shoveling of each layer of below ground successively downwards, and successively carry out the construction of each layer basement floor downwards, all accomplish the excavation that just carries out lower floor's earthwork after this floor plate construction at every turn.
For the work items that comprises high building and multilayer podium in the super highrise building, high building district foundation ditch and podium district foundation ditch carry out along practice construction usually simultaneously, yet because high building district floor is a lot; The shared duration is long partially, accomplishes in the podium district when binding, and the high building district accomplishes also poor quite a lot of a period of time from construction; High building district and podium district are accomplished around; Prolonged the time of completion of whole construction project, in addition, high building district foundation ditch and podium district foundation ditch carry out causing the construction plant not enough along practice construction simultaneously; And the sedimentation relatively more easily of foundation ditch periphery, environment pollutions such as construction noise and airborne dust are serious; In addition, also have the part engineering to adopt and earlier the podium district carried out reverse construction, however the high building district duration that construction consumes in later stage delayed whole time of completion, make this foundation ditch design scheme also have drawback.
Summary of the invention
Technical problem to be solved by this invention has provided a kind of method for designing of super highrise building deep big foundation pit, how to plan as a whole to design the foundation ditch construction of high building district and the foundation ditch construction of podium district makes whole construction period be in best problem to solve.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: the super highrise building deep big foundation pit is divided into high building district foundation ditch and podium district foundation ditch; Said high building district foundation ditch is carried out pile foundation and foundation pit enclosure structure construction; Said high building district foundation ditch is carried out suitable the construction, and said podium district foundation ditch is carried out pile foundation and foundation pit enclosure structure construction; Treat the high building structure return build accomplish basement roof after, said podium district foundation ditch is carried out adverse construction method.
Further, when said podium district foundation ditch carries out adverse construction method, utilize of the support of the structural beams plate body system of big rigidity as said podium district foundation ditch.
Further, when said podium district foundation ditch was carried out adverse construction method, said high building structure was carried out the above construction in ground.
Further, return to build in the high building structure and said podium district foundation ditch is carried out adverse construction method after accomplishing basement roof, said each floor plate of high building structure basement is docked with each floor plate of basement in said podium district.。
Further, the superstructure number of plies in said high building district is more than or equal to 50 layers.
Further, the superstructure number of plies in said podium district is less than or equal to 8 layers.
The method for designing of super highrise building deep big foundation pit provided by the invention and since the duration that the high building district builds than podium district build long in time limit, therefore; Earlier high building district foundation ditch is carried out along constructing; Can guarantee that high building binds as early as possible, plan as a whole the high building district foundation ditch of design and build and the construction of podium district foundation ditch, make whole construction period be in a best time value; Simultaneously; When high building district foundation ditch is carried out operation, can utilize the podium district that does not begin as yet to construct as the construction plant, the problem that the construction plant that possibly run into when having solved high building district excavation of foundation pit is not enough; Treat the high building structure return build accomplish basement roof after, said podium district foundation ditch is carried out adverse construction method, to reduce high building district and the interval of podium district deadline; Thereby make the time of accomplishing the duration plan as a whole to reach best, in addition, the podium district carries out adverse construction method; The top board in podium district that can utilize completion is as the construction plant in high building district and podium district; Simultaneously, podium district foundation ditch adverse construction method can reduce construction noise, airborne dust etc., to avoid that explosion takes place when making in the construction supporting removal; Reduced the influence of engineering construction, fully implemented the requirement of green building technology surrounding enviroment.
Further, when said podium district foundation ditch carries out adverse construction method, utilize of the support of the structural beams plate body system of big rigidity, help controlling the safety and stability of foundation pit enclosure structure structure as said podium district foundation ditch, thus the better protect surrounding enviroment.
Further, return to build in the high building structure and said podium district foundation ditch is carried out adverse construction method after accomplishing basement roof, said each floor plate of high building structure basement is docked with each floor plate of basement in said podium district., so that the structure level force transfer system is continuous between the zones of different, to guarantee the stable of whole building structure.
