Further, the a-quadrant and B regions are two relative regions, respectively positioned at C regions both sides.
Further, the area equation of the a-quadrant and B regions.
Further, the lower section of building bottom plate 11 is additionally provided with former engineering pile 10.
It is used for the method for correcting error of the rectifying of leaned building structure of stake end sandy soil supporting course described in a kind of claim 1, including
Following steps：
A bottom plate 11) is distributed according to building superstructure load assignment, differential settlement situation and former engineering pile 10
Region opens up piling hole, then divides the class of A, B, C tri- stake subregion；
B) construction A classes stake, piling completes to carry out envelope stake using prestressing apparatus 6 at once, then carries out the stake piling of B classes, complete
Stake wouldn't be sealed after into piling, the permeable hole reserved by stake end carries out water filling, disturbance stake end sandy soil makes the relatively rapid production in the side
Raw certain sedimentation；At the same time, crossed construction C classes stake, sets certain thickness compressible material 9, and use in time in stake top
Concrete seven carries out envelope stake；
C) according to monitoring materials, after the building time amount of inclining meets design requirement, certain thickness is set to B classes stake stake top
Compressible material 9, and carry out envelope stake.
Further, step B is carried out) and step C) when, the thickness of the compressible material 9 in the piling hole of B classes is big
In the stake of C classes.
The beneficial effects of the present invention are：
1) according to the situation of sedimentation, building bottom plate is divided into three different regions, each region anchor rod static pressure pile driving construction
Carry out in particular order, and use different envelope piling method combination water injection methods, return building and incline, reach the effect of correction
Really；
2) rectifying of leaned building effect preferably, can be implemented to carry out construction adjustment during correction according to actual conditions；
3) while the safety and reliability of Deviation Correction Construction is higher.
