Description
Technical field
The invention belongs to civil construction fields, and in particular to a kind of frame structure building lifting correcting method.
Background technology
Building inclination rectification means that building causes basic unevenness due to certain of ground, basis or building itself
Even sedimentation, upper part structure deviate upright position and run-off the straight, when the inclined degree of building is more than that the related specification of country is wanted
Ask, seriously affect taken when building safety and normal use to ensuring building safety and restore its normal use
Stable measure is reinforced in the rectification righting of function.
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, are carried out to soil digging amount, irrigation quantity a large amount of theoretical
It calculates, it is empirical very strong, it is theoretical also immature.In fact big side will be settled to be lifted building, can equally reach and entangle
The purpose inclined, 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 lifts for frame structure building
Rise correcting method.
In order to achieve the goal above, the technical scheme is that：
A kind of frame structure building lifting 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, cruelly
Expose the isolated footing below frame column at this；
2) it drills downwards the working pit bottom excavated since step 1), until hard bearing stratum；
3) steel reinforcement cage is placed in drilling, concrete perfusion forms cast-in-place concrete pile；
4) support device is horizontally disposed on frame column；
5) lifting apparatus is placed between bored concrete pile top surface and support device；
6) frame column for settling major part and isolated footing are lifted by support device with lifting apparatus, were lifted
The differential settlement between building inclination rate and frame column is measured in journey；Differential settlement between building inclination rate and frame column
Less than stopping lifting after tolerance as defined in specification；
7) it interspaces interior casting concrete in isolated footing and foundation soil.
Further, drilling machine is installed in the isolated footing surrounding, drilling machine drilling is up to hard holding force
Soil layer.
Further, the drilling is at least arranged two, two or more drillings are the four of the isolated footing
Week is uniformly distributed.
Further, the support device is concrete hanging top.
Further, the construction method of the concrete hanging top is：In two lateral extent isolated footing end face of frame column
At certain altitude position, concrete hanging top is arranged by the method for being implanted into reinforcing bar and casting concrete, Cantilever Beams both ends should prolong
It extends to above the bored concrete pile of both sides, the arrangement of reinforcement of Cantilever Beams should ensure that does not generate destruction in the case where being lifted load action.
Further, the lifting apparatus is jack.
Further, jack is placed between bored concrete pile top surface and concrete hanging top.
Further, further include step 8), after concrete curing reaches some strength, remove jack.
Further, further include step 9) assembling reinforcement between Cantilever Beams and bored concrete pile, supporting module, pouring reinforcement
Concrete column；Frame column load is not only transferred to foundation soil by isolated footing, but also is transferred to by Cantilever Beams, bored concrete pile
Hard bearing stratum prevents isolated footing from further sedimentation occurs.
Further, further include step 10) backfilling working hole, restore ground.
Beneficial effects of the present invention are：
The method being lifted using jack, simpler compared to the method for forced landing, safe, controllable, it is heavy to estimate in advance
Drop amount, soil digging and irrigation quantity, it is only necessary to intuitively complete rectification using conventional measurement means.It is bored in isolated footing end face
Hole construction bored concrete pile is compared, and difficulty of construction is reduced.
