Servo support and construction method thereof

The invention relates to a servo support and a construction method thereof, the servo support comprises a concrete support, a steel rib is arranged in the concrete support, one end of the steel rib abuts against an enclosure body through a jack, and the other end of the steel rib is poured in the concrete support. The construction method comprises the steps that after the upper-layer concrete support is constructed, the lower-layer concrete support is partially constructed; steel ribs are erected, one end of each steel rib abuts against a currently-constructed concrete support, and the other end of each steel rib abuts against the enclosure body through a jack; the concrete supports and the concrete enclosing purlins in the edge areas continue to be poured; and the jack carries out subsequent loading. According to the servo support and the construction method thereof, the steel ribs used for supporting are arranged in the edge concrete support, the pre-jacking force is applied in advance, the problem that a c
