s2: reliably connecting the newly-added bearing platform with an original bearing platform;
s3: constructing a anchor rod static pressure pile in the pile pressing hole;
s4: utilizing a jacking system and the anchor rod static pressure pile to jack up the newly added platform and the original bearing platform;
s5: cutting off the original pile of the original bearing platform;
s6: jacking the newly-added platform and the original bearing platform by using the jacking system;
s7: completely filling gaps below the newly added platform and the original bearing platform;
s8: and sealing the pile pressing hole.
Preferably, in the step S2, the newly added bearing platform is reliably connected to the original bearing platform in a manner of bar planting and chiseling.
Preferably, the step of S3 further comprises the steps of:
s31: constructing a anchor rod static pressure pile in the pile pressing hole;
s32: pile repairing is carried out on the anchor rod static pressure pile to obtain a repaired pile;
s33: and filling the filling pile with a core by using concrete.
Preferably, in the step S4, the jacking system includes a jack and a transmission rod; the dowel bar is arranged at the top of the pile repairing and partially extends out of the pile pressing hole; the jack is arranged at the top of the dowel bar and connected with the newly added bearing platform.
Preferably, in the step S5, a pile cutting working surface is excavated from a side of the original bearing platform far from the new bearing platform, and the original pile of the original bearing platform is cut.
Preferably, in the step S7, the gap below the new platform and the original platform is completely filled with cement slurry.
Due to the adoption of the technical scheme, the invention has the following beneficial effects:
the method for adding the bearing platform and filling the pile can be suitable for various soil layers, and the single pile has high bearing capacity and can provide larger jacking force. A large amount of soil bodies do not need to be excavated downwards, and the construction is simple and convenient. The hole sealing method is simple and has low technical requirements. And the building jacking can be smoothly completed without cutting structural columns, shear walls and other members and influencing the integrity, safety and reliability of the original structure.
