The invention relates to a hydraulic prop jig frame for segmented construction of a tension leg platform. The hydraulic prop jig frame comprises a base, an upright installed on the base and a top support pillar which sleeves on the top of the upright and can be detached, wherein the upright comprises a hollow upright body and a lifting prop located in the upright body, the length of the lifting prop is shorter than that of the hollow upright body, the upper end of the lifting prop can abut against the top support pillar so as to drive the top support pillar to rise and fall, and a connectable hydraulic system is formed by a hollow structure between the bottom of the lifting prop and the base, so that a height-adjustable hydraulic oil cylinder is achieved. According to the hydraulic prop jig frame for segmented construction of the tension leg platform, a previous screw-type support pillar structure is eliminated and changed into the top support pillar which is installed on the top of the upright on the base in a sleeving manner and can be detached, so that installation of the top support pillar is convenient to achieve, and the time waste in the process of installing or detaching the top support pillar is avoided; and the hydraulic-driving lifting prop is used for abutting against the top support pillar for enabling the top support pillar to rise and fall, and stepless adjustment of height of the jig frame is achieved.
