Description
Technical field
The present invention relates to technical field of building construction more particularly to a kind of anchor pile underpinning to build underground without basement
The method of space increasing layer.
Background technique
Since decision-making brings parking difficulty problem to become increasingly conspicuous to big city now, urban land is nervous, price
Valuableness, building the underground spaces such as underground parking becomes a kind of suitable selection.80~nineties of 20th century, all parts of the country are built
It is largely built without basement, removing this batch of building, to rebuild then cost excessive, does not meet Resources for construction economizing type, environmental-friendly
The general plan of type harmonious society.
To solve to develop the underground of this batch of building under conditions of such as why not influencing normal use and rationally utilizing space
Space, we use Anchored Pile Foundation Underpinning technology, effectively realize the secondary use of the underground space.
Summary of the invention
A kind of method the purpose of the present invention is to provide anchor pile underpinning without basement building underground space increasing layer,
Have and extend basement effective use space, increase effective usable floor area of building, reaches three-dimensional, high efficiency utilizes
Urban land resource, and the construction period is short, the low advantage of project cost, solves existing building and builds without basement but remove weight
Build that cost is excessive, do not meet Resources for construction economizing type, environmentally friendly harmonious society general plan the problem of.
A kind of method of the anchor pile underpinning according to an embodiment of the present invention without basement building underground space increasing layer, tool
Steps are as follows for body:
S1: support construction: carrying out supporting construction around ground, is formed between stake and stake and is mutually twisted arrangement
A kind of foundation pit enclosure structure uses interlocking pile structural support；
S2: pile sinking and pile foundation underpinning: excavating foundation soil from indoor terrace, until former isolated footing end face, uses
The mode of anchor jacked pile carries out pile sinking, the vertical drilling in former isolated footing end face, by burying anchor pole on a stand alone basis
Prefabricated small square pile is pressed by fixed pile driving frame using the self weight of existing building as pressure pile reaction with jack out of piling hole
In soil, and synchronous grouting；After the completion of pile sinking, using envelope pile cover technology, static pressed pile and original basis is bound up, top is tied
Structure load is transferred to pile foundation from former isolated footing, carries out the construction of ground beam, ground beam and frame column in surface of base and interlocking pile connects
It connects；
S3: earth excavation and frame column are handled: being set well-points dewatering on the inside of foundation pit supporting construction, carried out light well point drop
Water excavates former isolated footing side and the bottom surface earthwork below, until at the designed elevation of proposed basement bottom board；It is excavated to and sets
After counting depth, basement bottom board construction is carried out at once, later, in former isolated footing end face inclined borehole, on former isolated footing
Frame column, which extend, to be poured to hole bottom, and extended frame column is formed；
S4: bottom slab concreting: cut out former isolated footing extra in addition to extended frame column and it is new on the basis of anchor rod static pressure
Stake, then pours basement bottom board, completes construction.
On the basis of above scheme, in the S1, the arrangement mode of stake is a not arrangement of reinforcement and mixed using extra retarded set element
Solidifying soil stake and a reinforced concrete pile arranged for interval.
On the basis of above scheme, in the S2, the ground beam and frame column, interlocking pile are using the connection side welded
Formula.
On the basis of above scheme, in the S2, aperture is the 80% of stake diameter.
On the basis of above scheme, in the S3, the deformation of stage detection building is excavated, original basis sedimentation is not more than
5cm, former isolated footing are supported by anchor jacked pile.
On the basis of above scheme, in the S3, using layering, piecemeal, symmetrical digging mode.
Compared with the prior art, the invention has the beneficial effects that: by interlocking pile structural support mode, utilize occlusion
The advantages of stake stiffness by itself and good water insulation effect, building structure can be close to, speed of application is fast, shortens the construction period, to ambient enviroment
Disturbance is smaller, and exterior wall permanent structure can be used as after basement is built up；Synchronous grouting is combined in pile sinking, can be improved anchor
The bearing capacity of rod static pressure pile improves pile foundation surrounding soil mechanical property, controls the sedimentation of superstructure, and use layering, piecemeal,
Symmetrical digging mode can control the uniform settlement of superstructure, by cutting out extra original in addition to extended frame column solely
The plane space that anchor jacked pile on the basis of vertical basic and new can reduce frame column is occupied for the effective of basement space
The influence utilized；The present invention is realized using anchor pile underpinning builds underground space increasing layer without basement, is not influencing to build
While stable structure, basement effective use space is extended, effective usable floor area of building is increased, reaches three-dimensional
Change, high efficiency utilize urban land resource, and the construction period is short, and project cost is low.
