白杨沟大桥钻孔灌注桩施工技术

Talking about the Bored Pile Construction Techniques Adopted in Baiyanggou Bridge

介绍了太长高速公路白杨沟大桥的施工经验,指出采用新型E25HD—R200型旋挖钻孔设备进行桩基施工,可以提高施工质量,加快施工进度,减少质量隐患,是保证钻孔桩质量和提前工期的有效措施。

This paper introduces the construction experiences in Baiyanggou Bridge on Taichang Superhighway, and points out that adopting new-type E25HD-R200 rotary drilling equipment in the construction of the pile foundation,which can improve the construction quality, speed the construction up, reduce the incipient quality faults, is an effective measure for guaranteeing the quality of the bored pile and shortening the construction period.
