桩柱式桥墩亦称排架墩,墩身是利用基础的桩基延伸到地面,项帽即为连接桩或柱的系梁。桩柱式桥墩的构造简单、用料少、施工快,在公路桥梁中应用较多。本文结合六盘水市中心城区城市快线工程桩柱式桥墩施工,总结分析桩柱式桥墩施工工法,提出以门式脚手架代替落地式脚手架配合抱箍施工更为经济实用的施工方法以及增加支撑千斤顶解决中系梁、盖梁标高控制难的问题。
Pile pier also known as pier pier, pier body is the use of the foundation of the pile extends to the ground, the item cap is connected to the pile or column tie beam.
