Invention content
The purpose of this utility model is to provide a kind of foundation pit supporting constructions that working performance is excellent and underground structure, basis
Integrated structure.
The technical solution of the utility model is：
A kind of foundation pit supporting construction and underground structure, basic integrated structure, it is characterized in that：Supporting construction is by single or more
Stiff composite pile wall composition is arranged, often arranges support pile coping, middle part is connected by armoured concrete slab with underground structure, foundation pit
The top of interior row's supporting piling wall is combined closely by micro-expansion cement soil with outer wall of basement, the lower part of row's supporting piling wall in foundation pit
It is connected with the stiff composite pile in basis by the cement earth pile of grid-like lap connection.
Often row's stiff composite pile wall is inserted into peripheral cement earth pile by prefabricated pile and forms, and prefabricated pile can partly or entirely use pre-
Bracket is arranged in the top of bracket stake processed, the prefabricated bracket stake, and bracket and reversed bracket is arranged in middle part.When supporting construction is multiple rows of
, can be different per campshed wall top absolute altitude when stiff composite pile wall, outer campshed is high, and interior campshed is low, mixed by reinforcing bar respectively per campshed top
Concrete board and the top plate of underground structure, basement one plate, two laminate of underground etc. are connected.
Armoured concrete slab is prefabricated board or Bars In Poured Concrete Slab, one end and support pile coping Guan Liang or top bracket, in
Portion's collar tie beam or middle part bracket symmetrical above and below are connected, the top plate of the other end and underground structure, basement one plate, two laminate of underground, bottom
Plate etc. is connected.For armoured concrete slab in addition to both ends, middle section space set reserved opening facilitates backfill micro-expansion cement
Soil.
In foundation pit campshed wall lower part be located at foundation pit bottom surface pass through to the stiff composite pile periphery cement earth pile of lower part it is multiple rows of
The cement earth pile of grid-like lap connection is connected with the stiff composite pile in basis, and the resistance to compression withdrawal resistance on basis is transferred to foundation pit
In supporting construction；The row's spacing for overlapping cement earth pile is identical as the stiff composite pile spacing in basis, increases near foundation pit walls side
Addend root overlaps cement earth pile and concrete perfusion ensures strength of joint, and the depth for overlapping cement earth pile is no more than pattern foundation pit supporting structure
The depth of stake.
The utility model makes building foundation that the resistance to compression breakout capacity of supporting construction be utilized, it is possible to reduce basic resistance to compression resistance to plucking
The quantity of stake.Foundation area is expanded as the area of entire foundation pit by original base areas（Increase fertile slot and supporting construction
Area）, take measures to be reliably connected with underground structure and basis from supporting stake top to stake bottom, collaboration carrying, overall stability
It is good, building settlement can be reduced.
