Straddle-type monorail bridge with large line space T piers, and design method for T piers thereof

Abstract

The invention discloses a straddle-type monorail bridge with large line space T piers. The straddle-type monorail bridge comprises track beams, as well as a plurality of large line space T piers arranged under the track beams; each large line space T pier comprises a pier column (2), a capping beam and pad stones (5), and the capping beam comprises standard segment capping beams (3) and change segment capping beams (4) arranged at the two ends of the capping beam transversely; the structures and sizes of the standard segment capping beams (3) in each large line space T pier are the same; the end height of the change segment capping beams (4) is the same as the end height of the standard segment capping beams (3); and the transverse lengths of the change segment capping beams (4) of different large line space T piers are the same or different. The invention further discloses a design method for the large line space T piers of the straddle-type monorail bridge. According to the straddle-type monorail bridge, the length of the change segment capping beams only needs to be designed according to the line space, and the workload for design and drawing is reduced; and meanwhile improvement of the repeated utilization ratio of templates is benefited.

Description

technical field [0001] The invention belongs to the technical field of rail transit bridge structures, and more specifically relates to a straddling monorail bridge with large line spacing T piers and a design method for the T piers. Background technique [0002] Straddle-type monorail traffic is a kind of urban rail transit. Because straddle-type monorail has many advantages such as good landscape, low cost and low noise, the construction period of straddle-type monorail traffic is often less than half of the subway construction period, and the cost is also lower. It is only about one-third of the subway, but it is a medium-capacity rail transit system, which can greatly improve the city's traffic problems. At present, domestic third- and fourth-tier cities are very enthusiastic about straddle-type monorail transportation, and many cities are planning and building monorail transportation, which has great market potential. [0003] The design of bridge piers of straddling m...

Problems solved by technology

[0005] 1. When setting up a single-column large-arm T-pier, because the line spacing of each pier is different, the size of the cover beam of each pier is different, and the straddle monorail line usually has dozens or even hundreds of large line spacing The length and height of bridge piers and cap girders are designed according to the line spacing corresponding to each bridge pier, which increases the workload of design drawing in the design;

[0006] 2. When there are many T piers with large line spacing, the workload of drawing T pier reinforcement diagrams is increased, and the design efficiency of straddling monorail large line spacing T piers is reduced;

[0007] 3. Since the size of the cover beams of each pier is different, corresponding formworks of different sizes are required, which increases the use of formwork during construction and increases the production cost of formwork
