Order, is effectively facilitated the raising of the limited parking stall utilization rate in parking lot, stopping at release problem, therefore, the demand of intelligent parking garage
Rise constantly.
At present, existing building type of foundation mainly has following several：(1) isolated footing, in the isolated footing individually excavated
Middle pouring reinforcement concrete, uneven soil property is constructed, construction is uncomplicated；But when upper load is larger, using independence
Basis relatively wastes, and when soil property is uneven, isolated footing settlement difference is larger.(2) strip footing, bending rigidity is big, will
Top load is converted into uniform load, makes basic stress more uniform；It is more unrestrained but strip footing construction is complex
Take, scene uses cast-type operation, and construction period is longer.(3) raft foundation, the compressive load per unit area of foundation soil can be reduced, carried
High foundation bearing capacity, and strengthen the integral rigidity on basis；But raft foundation volume is larger, casting concrete amount during construction
Greatly, construct more complicated, economy is poor.(4) pile foundation, has higher bearing capacity, and antidumping and sidesway to building have very
High guarantee；But cost is higher.
As can be seen here, traditional infrastructure form all inevitably needs excavation and construction.But in some large- and-medium size cities
In the case that housing-group is intensive, underground utilities are intricate, excavation of foundation pit is carried out, inevitably to Adjacent Buildings, pipeline
And the security of other underground installations constitutes a threat to.When especially excavation of foundation pit frontier distance existing building is close, foundation ditch
Additional shearing and moment of flexure can be applied to close to buildings and its basis by excavating soil body movement caused by off-load, and even more serious
Be so that the foundation soil of settlement stability due to settling again already, and particularly the mixed old building of brick is to uneven heavy
Drop very sensitive.
Therefore, it is significant to design a kind of foundation structure in digging-free assembled stereoscopic garage.
