Embodiment
The utility model is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1-12, a kind of unilateral underpinning structure in brick wall pedestal foot basis, including original basis bed course 1, brick wall 3, L
Shape underpins translation building block 6, transform beams 8, steel reinforcement cage 5, pile cover 9；Horizontal cross perforate on brick wall 3, L-shaped underpin translation building block
6 insert in the hole；Transform beams 8, underpin translation building block 6, original basis bed course 1 pours integral, and it is vertical to be reserved on the transform beams
Stake holes 7；Steel-pipe pile 4 is provided with stake holes 7, steel reinforcement cage 5 is arranged outside steel-pipe pile 4；Concrete perfusion fills out core in steel-pipe pile 4, support
Change the top casting concrete pile cover 9 of beam 8.
Referring to 10,12, it is described underpin translation building block 6 it is vertical with steel-pipe pile 4, staggeredly, alternate setting.
Referring to 7,9, the transform beams 8 are arranged on the outside of brick wall, and the dress L-shaped underpins the end of translation building block 6 and brick
The inner side of wall 3 is concordant.
Referring to Fig. 8,10, the stake holes 7 is square hole.
Referring to Fig. 9,11, the bottom of brick wall is pressed close in the position of horizontal cross perforate on brick wall 3.

The model for underpining translation building block type, wall thickness, length and steel-pipe pile that is used in the present embodiment, the section of transform beams
Size, arrangement of reinforcement are calculated according to brick wall bearing load and determined.
This example is in the specific implementation：It is circle first in the perforate of wall one side, porthole, there is arching, only produce ring
To shear force, perforate terminates afterwards rapidly to insert the translation building block 6 that underpins in corresponding aperture in porthole, underpins translation building block 6 and uses type
Steel is welded to connect, and underpins translation building block 6 and brick wall load is play supporting role, and controls deformation of wall；Reserved stake holes 7, pours coagulation
The newly-increased collar tie beam of soil, anchor jacked pile construction is carried out after collar tie beam maintenance to design strength；After the completion of piling, steel reinforcement cage 5, steel are placed
Muscle cage length determines according to actual conditions；Steel reinforcement cage is placed in steel-pipe pile and concrete perfusion, finally by coagulation grave stake,
Steel-pipe pile and newly-increased collar tie beam are poured integral.Underpin translation building block 6, steel-pipe pile 4 is connected with transform beams 8 by concreting
It is integral, underpin translation building block 6 and form firm domain with newly-increased collar tie beam connecting portion, will effectively can be made because of unilateral underpinning bias
Into moment of torsion and Shear transfer to steel-pipe pile, Path of Force Transfer is clear and definite, easy for construction.
Above is preferred embodiment of the present utility model, those of ordinary skill in the art can also be carried out respectively on this basis
Kind conversion improves, and on the premise of the total design of the utility model is not departed from, these conversion or improvement should also be as belonging to this reality
Within the scope of new be claimed.
