Into tree root shape.It is laterally long equivalent to pile foundation under column 30 after slurries horizontal infiltration enters the Soft Soil Layer of 20 lower part of foundation stabilization platform
Go out multiple " roots ", and be linked to be an entirety with " the vertical main root " of pile foundation under column 30, so as to increase pile foundation 30 and weak soil under column
Frictional force between layer, effectively improves the load-bearing capacity of pile foundation 30 under column.
As shown in Figure 1, it is characterised in that pile foundation 30 is by controlling grouting pressure to form what is gradually increased from top to bottom under column
Pile foundation 30 is up-small and down-big structure under skirt ladder type, i.e. column, and this structure can effectively improve the support energy of pile foundation 30 under column
Power, prevents that sedimentation phenomenon occurs in pile foundation 30 under column.
Preferably, pile foundation 30 is distributed in the surrounding of building bearing column under column.Pressure of the building bearing column for building foundation
Maximum, this position are easiest to sedimentation phenomenon occur, by pile foundation 30 under setting column in the surrounding of building bearing column, so as to improve
The structural strength and enabling capabilities of building bearing column lower part building foundation so that lifting occurs in building bearing column.
Preferably, pile foundation is using the integral protrusive delamination pour slurry construction technology of note is bored under column, and the technique aperture is small, and slip casting is deep
Degree is big, and downward slip casting is layered by top, avoids secondary settlement from destroying, slurry infiltration evenly, and is put down by high-pressure slip-casting
Steady lifting building foundation, reaches in design requirement deviation range.
It can be seen from the above description that the above embodiments of the present invention achieve the following technical effects：
By way of reinforcing layer by layer, pile foundation 30 forms three under bed course reinforcement and strengthening layer 10, foundation stabilization platform 20 and column
Dimensional support system is tieed up, first carries out building foundation reinforcing, then carries out building foundation lifting, realizes that building foundation is reinforced and lifting is entangled
Partially integrated purpose, successfully solves the purpose on building differential settlement and lifting correction basis, building foundation is reached carrying
In the range of power requirement and design tolerance.
