A building inclination correction truncated pile underpinning structure, comprising: the pile comprises a pile 100, a jack 2 and a supporting structure 1;

the original pile 100 is an original pile 100 to be cut off on a building site, and a precast slab a100 is arranged above the original pile 100; wherein, the side wall of the original pile 100 is provided with a positioning hole a101 with an axis intersecting with and vertical to the axis of the original pile 100; the original pile 100 is inserted into the positioning hole a101 so that the axis of the original pile 100 is perpendicular to the axis of the original pile 100; the supporting structure 1 is arranged in the positioning hole a101; more specifically, the support structure 1 includes a support column 11 inserted in the positioning hole a101, and the support column 11 is preferably integrally cast by using reinforced concrete through a mold; after the support column 11 is inserted into the positioning hole a101, the axis of the support column 11 is intersected with and perpendicular to the axis of the original pile 100; wherein, a supporting plate 111 is arranged at the upper end of the supporting column 11, and a jack 2 which is abutted against the bottom of the precast slab a100 is arranged on the surface of the supporting plate 111; the mounting position of the jack 2 is positioned right above the support column 11; so arranged, the pressure borne by the jack 2 is supported by the support column 11, and the support column 11 is connected with the original pile 100, so that the support column 11 has better pressure;

more specifically, the bottom of the supporting column 11 is also provided with a supporting rod 3 connected with the original pile 100; the side wall of the original pile 100 is provided with a fixing piece 4 used for supporting the supporting rod 3 below the original pile 100, and the fixing piece 4 is formed by splicing a plurality of semicircular rings; the fixing piece 4 is provided with an arc surface a4 corresponding to the outer wall of the original pile 100; the arc surface a4 is tightly attached to the side wall of the original pile 100; the fixed side wall is provided with a plurality of fastening bolts 41; the fastening bolt 41 fixes the fixing member 4 to the side wall of the original pile 100; wherein, the surface of the fixing piece 4 forms a fixing groove a41 corresponding to the supporting rod 3;

more specifically, the fixing groove a41 is recessed in a surface portion of the fixing member 4 and extends in a circumferential direction of the fixing member 4; the fixing groove a41 forms a fixing hole a411 with a bolt or a portion corresponding to the support column 11; wherein, the connection part of the support rod 3 and the fixing piece 4 forms a support block 42 inserted into the fixing hole a411; the end part of the supporting block 42 is hinged with the supporting rod 3; since the fixing hole a411 corresponds to the bolt, the position strength of the fixing member 4 at the fixing hole a411 is maximized; after the supporting block 42 is arranged in the fixing hole a411, the strength is enough to support the pressure transmitted by the jack 2, so that the stability is improved.
