Embodiment Construction

[0012] The present invention will be further described below in conjunction with the drawings and embodiments.

[0013] Reference figure 1 , The present invention is a ballastless track long-span high-speed railway arch bridge arch-over-arch structure, including a main arch 10, a left side junction pier 11a, a right side junction pier 11b, an upper arch pier column 12 and an upper arch beam 13, the left side The junction pier 11a and the right junction pier 11b are respectively arranged on both sides of the main arch 10, and the upper arch pier columns 12 fixed with the main arch 10 at the lower end are arranged at intervals along the bridge direction. The arch upper beam 13 is a continuous structure within the span of the main arch 10, and is consolidated with the upper ends of the left and right boundary piers 11a and 11b, and is connected to the upper ends of the upper piers 12 of each arch through supports.

[0014] Reference figure 1 , The upper arch beam 13 is a seamless co...

Abstract

The invention relates to a spandrel architectural construction of a ballastless track wide-span high-speed railway arch bridge. According to the construction, the problem that the deformation of corners of beam ends of spandrel beams is out of gauge is thoroughly solved, the smooth degree of a bridge floor is effectively improved, and the requirements of the technical conditions of a wide-span arch bridge ballastless track are met. The driving comfortability and the driving safety are improved, the construction cost of the bridge is reduced, and the later stage operation management and conservation are facilitated. The spandrel architectural construction comprises a main arch, a left junction pier, a right junction pier, spandrel pier columns and spandrel beams, wherein the left junction pier and the right junction pier are respectively arranged on two sides of the main arch, the spandrel pier columns of which the lower ends are in fixed junction with the main arch are arranged at intervals along the bridge. The spandrel architectural construction is characterized in that the spandrel beams are in continuous construction within the span range of the main arch, are in fixedly junction with the upper ends of the left junction pier and the right junction pier, and are connected with the upper ends of the pier columns of arches through a supporting seat.

Description

Technical field [0001] The invention and the bridge particularly relate to an arch-on-arch structure of a ballastless track long-span high-speed railway arch bridge. Background technique [0002] With the rapid development of high-speed railways in my country in recent years, large-span bridges of high-speed railways across mountainous canyons will inevitably emerge in large numbers. As a commonly used bridge type, arch bridges not only have greater spanning capacity and overall rigidity, but also Well combined with the canyon terrain, it has become the main bridge type for high-speed railway crossing the canyon terrain. [0003] At present, the arch structures of railway long-span arch bridges mainly adopt porous simple-supported beams or multi-connected continuous beam structures, and the upper beams of the arch have "broken joints". For example, the Beipanjiang Bridge with a main span of 236m on the Shuibai Railway, built in 2000, has a 10-hole and 24m simple beam system on the ...
