Abstract
The present application discloses a prestressed tube section structure and a construction method thereof. The prestressed tube section structure includes multiple successively connected segments. A shear-resistant structure and a water stop system are arranged between two segments; multiple prestressing tendons are arranged in the tube section along the circumferential direction of the tube section; and each prestressing tendon is communicated along the longitudinal direction of the tube section, and is partitioned into multiple sections at a position close to a segment joint. By the arrangement of the multiple successively connected segments of the present application, the shear-resistant structure and the water stop system are arranged between the two segments, so that a portion between two segments may bear a shear force and have watertightness; the arrangement of the multiple prestressing tendons in the tube section enables the multiple segments to be connected in series and spliced into a whole; in addition, each prestressing tendon is partitioned into multiple sections at the position close to each segment joint, so that the tube section has higher flexibility on the premise …
