Problems solved by technology

[0004] It can be seen that with the increase of the speed and the height of the long-span high pier, the amount of concrete used for the pier body will increase geometrically in order to meet the dynamic performance of the bridge when the traditional design of the broom-shaped hollow high pier structure is adopted. The cost of the project will increase substantially

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] refer to figure 1 , the long-connected, long-span continuous structure bridge herringbone super-high hollow pier of the present invention includes a pier body and a cap 30 consolidated therewith. The lower section 20 of the pier is composed of two outriggers 21, 22, the top of which meets the upper section 10 of the pier to form a herringbone-shaped pier in frontal projection. The lower ends of the two supporting legs 21, 22 are respectively consolidated with the bearing platform 30; the upper section 10 of the pier body and the supporting legs 21, 22 adopt hollow sections.

[0020] refer to image 3 , the upper section 10 adopts a rectangular hollow section with a transverse circular arc surface, which is similar to the section of a traditional hollow pier. refer to Figure 5 and Figure 6 , the legs 21, 22 adopt a transverse arc-shaped rec...

Abstract

The invention relates to an inverted Y-shaped superhigh hollow pier for a large-span long continuous structural bridge, which can greatly save the pier masonry quantity and obviously reduce the construction cost on the premise of ensuring the safety of the entire structure. The inverted Y-shaped superhigh hollow pier comprises a pier body and a bearing platform (30) fixedly connected with the pier body, wherein the lower segment (20) of the pier body is composed of two support legs (21 and 22), and the tops of the two support legs converge with the upper segment (10) of the pier body, thus forming the pier body of which the front projection is in an inverted Y shape; the lower ends of the two support legs (21 and 22) are fixedly connected with the bearing platform respectively; and the upper segment (10) of the pier body and the support legs (21 and 22) adopt hollow sections.

Description

technical field [0001] The invention relates to a bridge pier, in particular to a herringbone-shaped super-high hollow pier applied to a long-connected, long-span continuous structure bridge of a high-speed railway. Background technique [0002] With the rapid development of transportation, large-span bridges across rivers and canyons will inevitably emerge in large numbers. Due to the extremely complex geological and landform characteristics of railway construction in western my country, various unfavorable geology and steep slope canyons emerge in endlessly, and long-span long-connected structures and super-high piers will be inevitable. [0003] At present, the railway bridge with the largest pier height in China is the Dukou River Bridge on the Yiwan Railway, with a design speed of 160km / h. 128m, with a broom-shaped hollow pier; the largest-span railway rigid-frame bridge is the Niujiaoping Bridge on the Xiangyu Line, the main bridge is (100+192+100)m prestressed concre...
