我们在豫北某地采用钻孔灌注桩修建5孔10米装配式钢筋混凝土桥,每座墩台由钻孔直径为80厘米、深24米、每根设计承载力为107吨的两根桩柱组成。全桥12根钻孔桩柱,连同墩台盖梁在内,历时36天全部完成。施工速度快,而且免去水下作业和围堰抽水等困难工程,大幅度地降低了造价。这次施工中,吸取了兄弟单位的很多有益经验,使全桥工程能顺利完成。兹将其中点滴经验介绍如后:
We use a bored pile in northern Henan to build a 5-hole, 10-meter, prefabricated reinforced concrete bridge. Each pier consists of two piles with a hole diameter of 80 cm and a depth of 24 meters, each designed to have a carrying capacity of 107 tons Column composition. The whole bridge 12 bored piles, together with the abutment cap beam, which took 36 days to complete. Construction speed, but also eliminates the need for underwater works and cofferdam pumping and other difficult projects, significantly reducing the cost. In this construction, learned a lot of useful experience of the brothers unit, so that the bridge project can be successfully completed. I will introduce one after another experience as follows:
