When the mounting block 43 slides on the base 1, the grouting pipe 16 clamped by the first clamping piece 2 and the second clamping piece 3 on the mounting block 43 also slides on the base 1, so that a special constructor does not need to hold the grouting pipe 16 by hands and then grout the building foundation, the aim of unmanned grouting is achieved, and the manpower saving effect is achieved. The bottom of base 1 is equipped with a plurality of universal wheels 13, and the quantity of universal wheel 13 is specific can be four, and four universal wheels 13 set up four edges in base 1 bottom respectively, and the connected mode of universal wheel 13 and base 1 can be bolted connection simultaneously. Under the effect of universal wheel 13, this building foundation reinforced grouting support removes comparatively conveniently. In addition, in order to prevent the grouting support for reinforcing the building foundation from slipping during grouting, the bottom end of the base 1 is provided with a telescopic supporting leg 15, the sectional area of the supporting leg 15 can be trapezoidal, and the sectional area of the supporting leg 15 is gradually reduced from bottom to top. The cylinder body of the air cylinder 14 can be fixedly arranged on the base 1 through bolts, and the piston rod of the air cylinder 14 is fixedly connected with the supporting legs 15, so that the supporting legs 15 can correspondingly stretch relative to the base 1 when the piston rod of the air cylinder 14 stretches. The supporting legs 15 are supported on the ground by extending out the piston rod of the cylinder 14 during grouting, so that the grouting support is not easy to slide, and is stable during grouting.

Regarding the specific arrangement of the mounting block 43 sliding on the base 1, as shown in fig. 2, the grouting support for building foundation reinforcement further includes a first driving mechanism 4, the first driving mechanism 4 includes a first motor 41, a screw rod 42 and the mounting block 43, an output shaft of the first motor 41 is fixedly connected with the screw rod 42, and the fixed connection may be welding.
