Beschreibung
Zusammenfassung:	The utility model discloses a hydraulic jack adjustable support for pipe jacking construction, which is characterized in that more than two longitudinal beams uniformly divide the interior of a support frame into more than two layers of mounting cavities, and each layer of mounting cavity is internally connected with large H-shaped steel and small H-shaped steel in a sliding manner; more than two groups of limiting structures are symmetrically and fixedly arranged on the side wall of the mounting cavity, each group of limiting structures comprises three side plates, a sliding cavity is defined by every two adjacent side plates, the ends, close to each other, of the large H-shaped steel and the small H-shaped steel are slidably connected with the sliding cavities, the finish-rolled twisted steel is arranged in the mounting cavity, and two sleeves are in threaded connection with the finish-rolled twisted steel; the side face of each sleeve is rotationally connected with two connecting rods, the free end of one
