Example Embodiment

[0028] According to the attached figure 1 with figure 2 , Give the preferred embodiments of the present invention and describe them in detail, so as to better understand the functions and characteristics of the present invention.

[0029] See figure 1 with figure 2 , A method for rectifying deviation of building jacking in an embodiment of the present invention includes the steps:

[0030] S1: Set up a new cap 1 and reserve a pile hole 2 for the newly added cap 1.

[0031] S2: Reliably connect the new pile cap 1 with an original pile cap 3.

[0032] In step S2, the newly-added cap 1 and the original cap 3 are reliably connected by means of reinforcing bars and chiseling.

[0033] S3: Construct an anchor static pressure pile in the pile hole 2.

[0034] The S3 step further includes the steps:

[0035] S31: Construct an anchor static pressure pile in the pile hole 2;

[0036] S32: Obtain a supplementary pile 4 after supplementing the anchor static pressure pile;

[0037] S33: Use concrete...

Abstract

The invention provides a method for jacking rectification of a building. The method includes the following steps that S1, a newly added bearing platform is arranged, the newly added bearing platform reserves a pile pressing hole; S2, the newly added bearing platform is reliably connected with an original bearing platform; S3, an anchor rod static pressure pile is constructed in the pile pressing hole; S4, the newly added platform and the original bearing platform are supported by a jacking system and the anchor rod static pressure pile; S5, an original pile of the original bearing platform iscut off; S6, the newly added platform and the original bearing platform are jacked by the jacking system; S7, a gap below the newly added platform and the original bearing platform is fully filled; and S8, the pile pressing hole is sealed. According to the method for jacking rectification of the building, the damage to the building caused by jacking is reduced, damage to an original structure of the building is not required, and the safety is relatively high.

Description

technical field [0001] The invention relates to the technical field of jacking and rectifying, in particular to a method for jacking and rectifying a building. Background technique [0002] Current jacking correction methods include: [0003] 1. In the area where the settlement is relatively large, the structural column is underpinned first, then the column is cut off, and a jack is put into it for lifting. After the deflection is corrected to meet the design requirements, the jack is removed and the structural column is restored. [0004] 2. Cut out a hole in the shear wall in the side area where the settlement is large, put in a jack for underpinning, then cut off the remaining shear wall, and start jacking. After the jacking is completed, remove the jack and restore the shear wall. [0005] These two methods have damaged structural columns or shear walls, which need to be repaired later, which not only has a negative impact on the integrity, safety, and reliability of th...
