Abstract
The utility model relates to the technical field bridge structures, in particular to a double-rectangular columnar pier of high-speed rail. The double-rectangular columnar pier of the high-speed rail comprises two pier columns and a straining beam, wherein the two pier columns are fixed on a base, the straining beam is arranged at the upper portions of pier columns and two ends of the straining beam are respectively fixed in the two pier columns. The double-rectangular columnar pier of the high-speed rail is reasonable in structure, simple in construction, rapid and convenient to repair and maintain and good in durability. According to the double-rectangular columnar pier of the high-speed rail, two pier column structures with relatively small size are arranged below a bridge support, stress of the whole structure is explicit, the straining beam is arranged below the top of each pier column, requirements of transverse stiffness of the pier of the high-speed rail can be met, and the straining beam can be used as an operation platform for inspection and maintenance at the same time. The double-rectangular columnar pier of the high-speed rail is explicit in stress, reasonable in structure, economical, capable of well meeting requirements of intensity and stiffness of the pier of the high-speed rail, rapid and convenient to construct, simple in template design, fast in construction period and capable of prolonging the service life of the structure.
Description
Technical field
The utility model relates to the bridge construction technical field, is specifically related to a kind of high-speed railway double square columnar pier.
Background technology
The construction problem of high-speed railway bridge pier is the problem that receives much concern always, and the ballastless track bridge design, be generally rectangular solid pier, cylinder pier, rectangular hollow, board-like bridge pier etc. at present.The design of domestic high-speed railway bridge pier is generally adopted nose circle shape solid pier, hollow pier, rectangular solid pier, hollow pier.General solid pier is because the scale of construction is large, and bridge abutment moulding plate requires to adopt punching block from factors such as the bridge pier outward appearance are smoother, and because the bridge pier scale of construction is large, the steel that stencil design needs are many.And hollow pier has enough to meet the need slow, long construction period due to the internal mold constructional difficulties.Hollow pier particularly, due to the structure relative complex, construction quality is difficult to guarantee fully, and long construction period, often affects construction quality and duration of a project.
Thereby for the high speed bridge pier, how to choose rational form of structure, to overcome the high speed bridge pier to the requirement of pier stiffness, again can convenient construction, maintenance, improve the endurance quality of structure, guarantee the application life of structure, this is to demand one of key technology of studying and solving urgently.
Summary of the invention
The purpose of this utility model is for above-mentioned technical problem, provides a kind of and can satisfy high speed bridge pier intensity, rigidity requirement, convenient and quick construction, the high-speed railway double square columnar pier that stencil design is simple, the construction turnover is fast.
The technical solution of the utility model is: high-speed railway double square columnar pier comprises two pier studs that are fixed on base and is positioned at the binder on pier stud top, and it is inner that binder two ends are separately fixed at two pier studs.
Preferably, described pier stud is the solid concrete rectangular configuration, is highly 100-150m, and the pier stud top is provided with supporting seat, and the supporting seat cross section is less than the pier stud cross section.
The utility model provide a kind of rational in infrastructure, construction is simple, maintenance is convenient, fast, the bridge pier structure of good endurance, and the pillarwork of two scale of construction less is set under bridge pad, total is stressed clear and definite.Under pier stud pushes up, binder is set, has both satisfied the requirement of high speed bridge pier lateral stiffness, can take into account the maintenance and inspection operating platform simultaneously.
The high-speed railway double square columnar pier structure that the utility model proposes, stressed clear and definite, structure rationally, good economy performance, can finely satisfy high speed bridge pier intensity, rigidity requirement, convenient and quick construction, stencil design is simple, the construction turnover is fast, the application life of guaranteeing structure.

Fig. 3 is the utility model top view.
The specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments, be convenient to be well understood to the present invention, but they do not consist of restriction to the present invention.
High-speed railway double square columnar pier as Figure 1-3 comprises the binder 2 that is fixed on two pier studs 1 on base 4 and is positioned at pier stud 1 top, binder 2 two ends are separately fixed at two pier stud 1 inside, the binder 2 that arranges had both satisfied the requirement of high speed bridge pier lateral stiffness, can take into account the maintenance and inspection operating platform simultaneously.Pier stud 1 is the solid concrete rectangular configuration, and the scale of construction is less, is highly 100-150m, and total is stressed clear and definite.Pier stud 1 top is provided with supporting seat 3, and supporting seat 3 can conveniently contact with bearing at the bottom of bridge, and supporting seat 3 cross sections are less than pier stud 1 cross section.
In order to make high-speed railway double square columnar pier structure have necessary strength and stiffness, guarantee its fatigue durability and reasonable economy, consider simultaneously convenient and quick construction, maintenance convenience, two pier stud spacings can be adjusted according to the spacing of bearing at the bottom of bridge, the binder height is 100cm and is positioned at from pier stud top 100cm eminence, and this is capable of regulating highly as required.
The utility model high-speed railway double square columnar pier structure, compare with conventional high speed bridge pier, bridge pier is not all established the top cap, and is simple in structure, and it is consistent with conventional rectangular hollow profile that two columned pier keeps, the concrete scale of construction is little, be very easy to the making of bridge pier external mold, the use of falling, two columned pier internal mold has especially also been economized, can reduce cost, can save the duration again, have good society and economic benefit.The utility model is initiated high-speed railway double square columnar pier structure, and to Railway Bridges And Piers, particularly the design of high-speed railway bridge pier has reference and reference.
