The pier structure of claim 6, wherein a second reserved slotted hole penetrating through the pier supporting beam is formed in the pier supporting beam, a fourth corrugated pipe is pre-buried in the second reserved slotted hole, and the second reserved slotted hole and the fourth corrugated pipe are equal in height; the fourth corrugated pipe sleeve is arranged on the outer side of the top end of the longitudinal rib, and the concrete pipe is connected with the bridge pier supporting beam through the fourth corrugated pipe.
8. The pier structure of claim 6, wherein if a second corrugated pipe is arranged outside the bottom end of the protective layer, a gap between the second corrugated pipe and the third corrugated pipe is filled with concrete.
9. The pier structure of claim 5, wherein the concrete pipe further comprises: a filler layer nested within the first bellows.
10. A manufacturing method of a pier structure is characterized by comprising the following steps:
step 1: fixing the first corrugated pipe in the longitudinal bars and the stirrups, and pouring and filling concrete on the longitudinal bars and the stirrups to form a protective structure outside the first corrugated pipe to form a concrete pipe; wherein, protective structure includes: the protective layer, a plurality of longitudinal bars and a plurality of stirrups; each longitudinal bar and each stirrup are spliced with each other and annularly arranged on the protective layer; the longitudinal bars are sequentially arranged at intervals in the protective layer along a ring shape, and the stirrups are sequentially bound on the longitudinal bars at intervals from top to bottom;
step 2: embedding a third corrugated pipe in a first reserved slot of a pier foundation; sleeving a second corrugated pipe outside the bottom end of the protective layer, erecting a concrete pipe in the first reserved slotted hole, and pouring concrete between the second corrugated pipe and the third corrugated pipe to connect the concrete pipe with the pier foundation; pouring self-compacting concrete into the first corrugated pipe to the top end of the protective layer;
and step 3: pre-burying a fourth corrugated pipe in a second reserved slot of the bridge pier supporting beam; and sleeving the top ends of the longitudinal ribs in the fourth corrugated pipe, supporting the pier supporting beam on the supporting part, and pouring self-compacting concrete in the second reserved slotted hole to complete the manufacture of the pier structure.
