Supporting integrated hydraulic servo device capable of self-adapting enclosure and construction method of supporting integrated hydraulic servo device

The invention relates to the field of foundation pit construction engineering, in particular to a supporting integrated hydraulic servo device capable of being self-adaptive to an enclosure and a construction method of the supporting integrated hydraulic servo device. According to the technical scheme, the device comprises a servo device and a steel support which are integrated, wherein the servo device comprises a shell; the jack group is arranged in the shell, and the output end of the jack group extends out of the shell; the end head plate is arranged at the end part of the jack group, the end head plate is hinged with the jack group through a spherical hinge, and the end head plate is positioned outside the shell. The device has the beneficial effects that the jack set and the end plate are arranged, the end plate is fixed to the jack set in a hinged mode, and therefore the jack set can push the end plate to form a certain angle, the situation that a connecting steel plate is partially disengaged is preve
