Description
Technical field
The invention belongs to civil construction fields, and in particular to a kind of building inclination rectification method.
Background technology
Building inclination rectification means that building causes basis uneven due to certain of ground, basis or building itself
Sedimentation, upper part structure deviate upright position and run-off the straight, when the inclined degree of building be more than the related code requirement of country,
Seriously affect taken when building safety and normal use to ensuring building safety and restore its normal usage function
Rectification righting, reinforce stable measure.
The common method of rectification has：Pressing Ioad correcting method, soil digging correcting method, immersion correcting method and soil digging douche etc..
These methods are mostly to increase settling amount in the small side of building settlement, so as to adjusting the relative settlement on entire basis.To rise
To the inclined purpose of correction building.These methods need to estimate settling amount, and a large amount of theoretical meter is carried out to soil digging amount, irrigation quantity
It calculates, it is empirical very strong, it is theoretical also immature.In fact big side will be settled to promote building, can equally reach rectification
Purpose, and tilting procedure is simple, controllable.
Invention content
In view of the above shortcomings of the prior art, the object of the present invention is to provide a kind of promotions for frame structure building
Correcting method.
In order to achieve the goal above, the technical scheme is that：
A kind of frame structure lifting inclination-correcting method, includes the following steps：
1) working pit is excavated in the foundation soil in the relatively large region of settlement of foundation of the building of run-off the straight, exposure
Go out the isolated footing below frame column at this；
2) piling hole is opened up at the top of isolated footing, piling hole is low wide and up narrow broadening formation；
3) suspension hook is installed in the both sides in the piling hole at the top of isolated footing；
4) first segment prefabricated pile is placed vertically in piling hole, stake top is inserted in pile cover, and elevator is installed on pile cover, will carry
The hoisting rope of the machine of liter is connected with the suspension hook on basis top；
5) elevator is started, prefabricated pile is pressed into the foundation soil of ground beneath using building weight as counter-force；
6) when the prefabricated stake top of first segment is depressed near piling hole, pile cover and elevator are temporarily removed, in first segment stake
Apical grafting length the second section prefabricated pile, installs pile cover and elevator, continues to start elevator piling；
7) constantly spreading and piling, until first segment prefabricated pile pile top reaches hard soil layer；
8) continue to start elevator, since prefabricated pile is supported on hard soil layer, do not continue to, isolated footing can quilt
It is promoted；The differential settlement between building inclination rate and frame column is measured in basic lifting process；When building inclination rate and frame
Differential settlement between column stops being promoted after being less than tolerance as defined in specification；
9) pea gravel concreten is perfused being elevated in basis and foundation soil gap and piling hole.
Further, the minimum place aperture in piling hole not only needs receiving correction prefabricated pile, but also when considering rectification
Building isolated footing horizontal offset；
Further, suspension hook is installed by the method for bar planting.
Further, the piling hole number at least two, two or more drillings are in the isolated footing
Top be uniformly distributed.
Further, the total height of prefabricated pile, pile cover and elevator is usually no more than architecture bottom layer floor height.
Further, frame column fractional load is transmitted to prefabricated pile and heavily fortified point by the frictional force of pea gravel concreten in piling hole
Hard soil layer；Separately there is fractional load to be transmitted in foundation soil by the pea gravel concreten that ground beneath is filled；
Further, further include that step 10) removes pile cover and elevator, the basic prefabricated pile remaining at most of amputation；
Further, further include step 11) backfilling working hole, restore ground.
Beneficial effects of the present invention are：
It is simpler compared to the method for forced landing, safe, controllable using the method for promotion, settling amount need not be estimated in advance, draw
Soil and irrigation quantity, it is only necessary to intuitively complete rectification using conventional measurement means.In addition, superstructure load passes through prefabricated pile
It is transmitted with two paths of original basis, safety and reliability reduces posterior settlement.
