The utility model belongs to the technical field of tube wells, and particularly relates to a modular frame structure of an assembled tube well, which comprises a plurality of tube wells, a pair of long steel bars and a pair of short steel bars are respectively sleeved on the peripheries among the plurality of tube wells, and the adjacent long steel bars and short steel bars are connected through bolts. A plurality of spacing steel bars are connected between the two long steel bars through bolts, and the spacing steel bars are located between the two adjacent tube hoistways; the upper ends of the support joists are connected to the lower ends between the two long steel bars, the lower ends of the supporting stand columns are installed at the upper ends of the corresponding structural beams, the upper ends of the structural beams and the lower ends of the adjacent supporting stand columns are connected into a whole through the studs, and the structural beams provide upward-supporting horizontal supporting faces for the adjacent supporting stand columns. The lower ends of the supporting stand columns take the adjacent structural beams as fulcrums to lift the support joists upwards, the frame assembling process is completed, and the problems that an existing assembly type tube well modular frame structure is low in traditional construction efficiency and poor in safety are solved.
