Background technology
More difficult to the control ratio of environment deformation process when deep foundation pit construction, disposable excavation is larger on the impact of surrounding enviroment, and soil excavation huge in construction unloads, and the inner soil body resilience of foundation ditch will be also inevitable to the adverse effect on periphery stratum.
At present; for the safety that guarantees to close on important protection structure; reduce distortion risk out of control; general super-giant foundation pit adopts subregion excavation technique; first construct away from the subregion of protection building; treat that the excavation of foundation pit of constructing is in advance to hole bottom application work base plate, and upwards along accomplishing after ground floor, can excavate follow-up adjacent deep foundation ditch.
The subregion excavation construction method of prior art, exists long construction period, and programming is slow, the duration deficiency in economic performance of especially down town business land develop being utilized.
Utility model content
The purpose of this utility model is the synchronous space enclosing structure of excavating of a kind of deep foundation ditch subregion providing for the deficiencies in the prior art, adopt the subregion excavation structure of horizontal support, jump interval, storehouse synchronous excavation is set, make the environment adverse effect that excavation of foundation pit brings be reduced to bottom line, effectively reduce the impact that foundation ditch subregion is constructed on programming, safety and the environmental protection of the important structure of foundation ditch periphery in guaranteeing foundation ditch safety, are protected, be particularly useful for environmental protection sensitizing range and the disposable excavation open excavation on the larger deep foundation ditch of surrounding enviroment impact, improve duration economic benefit and social benefit, structural stability is good, excavation deformation and hole end resilience are little, the advantage that construction speed is fast.
The purpose of this utility model is achieved in that the space enclosing structure of the synchronous excavation of a kind of deep foundation ditch subregion, comprise the excavation of foundation pit district and the base plate of foundation pit that are surrounded by diaphragm wall, be characterized in that excavation of foundation pit district is divided into several and is provided with the excavation in zones of horizontal support structure by compartment wall, described horizontal support structure is made up of the ground floor structure floor, B1 structure floor and the underground two-layer structure floor that are arranged on steel structure column; Described ground floor structure floor, B1 structure floor and underground two-layer structure floor are connected for building with adjacent diaphragm wall and compartment wall.
Described steel structure column is arranged on castinplace pile.
Described compartment wall is that diaphragm wall or bored pile are constructed.
It is good that the utility model compared with prior art has structural stability; excavation deformation and hole end resilience are little; the advantage that construction speed is fast; and little to surrounding environment influence; operating efficiency is high; engineering risk is low; be particularly useful for the construction of deep foundation ditch under complicated surrounding enviroment condition; make the environment adverse effect that excavation of foundation pit brings be reduced to bottom line; effectively reduce the impact that foundation ditch subregion is constructed on programming, in guaranteeing foundation ditch safety, protected safety and the environmental protection of the important structure of foundation ditch periphery.
