Background technology
It needs that building basis is arranged below high-rise, building is formed and is supported, building basis bears to build
The whole load of object is built, and is passed it on ground.Common building basis is generally supported using foundation pile, and foundation pile can be beaten
It is formed and is supported to below ground lithosphere, certain projected depth can also be got to and form friction support.The basis of foundation pile support
Structural support is stablized, but underground structure is complicated, and construction cost is high.
Invention content
It is an object of the invention to solve the basic underground structure of building foundation complexity, the high problem of construction cost carries
For a kind of building well-sinking basis.
The technical solution adopted by the present invention to solve the technical problems is：A kind of building well-sinking basis, including building
Object, is equipped with building basis below building, and the building basis is well foundation, well foundation using open caisson construction and
At setting structure conversion layer connects between the top and building of well foundation, and the structural transition layer holds for armored concrete
Platform.This programme forms well foundation using open caisson, and construction cost is low, and stability of foundation is good, pit shaft top surface setting structure conversion layer
Support building, the pit shaft inner space plasticity below structural transition layer good.Can also be as needed, using pit shaft as
While main support system, reinforcement is carried out using pile foundation.
Preferably, underground garage is arranged inside the well foundation, underground garage is located at below structural transition layer, structure
Underground garage outlet is opened up on conversion layer.The inner space plasticity that pit shaft is located at below structural transition layer is strong, can be used as ground
Lower garage is utilized.
Preferably, the well foundation is single cylinder type basis or multi-cylinder type basis, each cylinder type basis
Diameter is no more than 40 meters.
Preferably, the well foundation is rectangular bucket foundation, rectangular cartridge type base side length is no more than 40 meters.
Preferably, the well foundation is the special-shaped bucket foundation being adapted to contour of building.
Preferably, the well foundation includes the shell and liner being located at below structural transition layer, the shell is upper
The straight-tube shape of under shed, liner are tubular, and side wall of inner is consistent with outer casing inner wall shape and there are gap, liner open-top,
Bottom is equipped with bottom plate, and the gap grouting reinforcement between shell and liner forms bonding course, and the bottom plate of the liner is equipped with mud
Hole, the mud hole use concrete enclosing, the support construction of support construction conversion layer are built in liner.Pit shaft shell barrel
It is thinner than common well sinking wall, be conducive to sinking control, inner shell bottom assembling reinforcement, casting concrete is formed and inner cylinder barrel one
The bottom plate of body sinks after reserving mud hole, and ponding may pass through mud hole, overcome sinking buoyancy, after sinking to bottom, between inside and outside shell
Grouting reinforcement, and close mud hole.It avoids assembling reinforcement, casting concrete in mud from making bottom plate, ensures construction quality.
Preferably, the well foundation is completed to construct according to the following steps：
A, shell sinks down into designed elevation；
B, liner carries out sinking down into designed elevation inside the housing, and mud hole is reserved on bottom plate for the ponding stream on the inside of shell
Enter liner；
C, grouting reinforcement is carried out between shell and liner；
D, the mud hole of interior plate is closed；
F, support construction is built in liner；
G, in the top wiretie casting concrete construction structure conversion layer of shell and liner.
Well foundation is used below building of the present invention, construction cost is low, and base support is reliable, and pit shaft inner space can
Plasticity is high, can be made full use of as garage；The open caisson construction of pit shaft use secondary sinking mode, bottom plate with liner it is prefabricated after under
It is heavy, difficulty of construction is reduced, ensures construction quality.
