Double-rectangular column type pier of high speed railway

Abstract

The invention relates to the technical field of a bridge structure, and particularly relates to a double-rectangular column type pier of a high speed railway. The double-rectangular column type pier of the high speed railway comprises two piers fixed on a base seat and straining beams located on the top portion of the piers, and two ends of the straining beams are fixed inside the two piers respectively. The double-rectangular column type pier of the high speed railway is reasonable in structure, simple in construction, convenient and fast to maintain, good in durability, the two piers with relative small mass are arranged below a supporting base of a bridge beam, and stress of the whole structure is clear. The straining beams are arranged below the tops of the piers, the requirement of a transverse stiffness of the high speed piers is met, and the straining beams can be used as an operation platform for checking and maintaining. The pier structure is clear in stress, the structure is reasonable, economy is good, requirements of the strength and the stiffness of the high speed piers are met, the construction is convenient and fast, the template design is simple, the construction process can move fast, and service life of the structure is assured.

Description

technical field [0001] The invention relates to the technical field of bridge structures, in particular to a high-speed railway double rectangular column pier. Background technique [0002] The construction of high-speed railway bridge piers has always been a matter of concern. At present, foreign high-speed railway bridge designs generally include rectangular solid piers, cylindrical piers, rectangular hollow piers, and slab piers. The design of domestic high-speed railway bridge piers generally adopts round-end solid piers, hollow piers, rectangular solid piers, and hollow piers. Generally, due to the large size of the solid bridge pier, steel formwork is required for the formwork of the bridge pier due to the smooth appearance of the bridge pier. However, due to the difficulty in the construction of the internal formwork, the hollow pier has slow turnover and long construction period. Especially for hollow piers, due to the relatively complex structure, it is difficult ...

AI Technical Summary

Problems solved by technology

However, due to the difficulty in the construction of the internal formwork, the hollow pier has a slow turnover and a long construction period.

Especially for hollow piers, due to the relatively complex structure, it is difficult to fully guarantee the construction quality, and the construction period is long, which often affects the construction quality and project schedule
