Highway frame type bridge abutment and construction method
The invention discloses a highway frame type bridge abutment and construction method. The highway frame type bridge abutment comprises an abutment body used for transmitting a main beam and loads on an upper portion of the main beam to a foundation, wherein the bottom of the abutment body is connected with a bearing platform playing a role in bearing and supporting the abutment body, and the bottom of the bearing platform is connected with a pile foundation extending to the underground and used for improving stability of the bearing platform; the abutment body comprises a front abutment body which is arranged on the top of one side of the main beam and connected with an abutment cap and a back abutment body which is far away from one side of the main beam, the tops of the abutment cap and the back abutment body are connected with a rigid frame beam, ear walls are symmetrically arranged on one side, far away from the main beam, of the rigid frame beam, and a supporting beam is connected between the bearing platforms. The bridge abutment can effectively solve an arrangement problem of the bridge abutment when the expressway crosses the road with poorer geology and the municipal road, can shorten the length of the bridge, saves the manufacturing cost, and can avoid the appearance of high and large cones.
本发明公开了一种公路框架式桥台及构筑方法，包括用于传递主梁及其上部荷载到地基的台身，所述台身底部连接有对台身起承载支撑作用的承台，所述承台底部连接有延伸至地下用于增加承台稳定性的桩基，所述台身包括安设于主梁一侧顶部与台帽连接的前台身和远离主梁一侧的后台身，所述台帽与后台身顶部连接有刚性框架梁，所述刚性框架梁远离主梁的一侧对称安设有耳墙，所述承台之间连接有支撑梁。本发明能有效解决高速公路跨越地质较差的公路、市政道路时桥台的设置问题，能够缩短桥长，节省造价，能避免高大锥体的出现。
