在市政桥梁中,由于道路路幅较宽、承台较小而长,或是单桩单柱、土质较软等情况,有些施工方法就不太经济实用。针对这种单桩单柱、路幅较宽、水深4m以内的跨河桥梁,采用在河道中打入木桩平台进行水中钻孔桩、墩柱及盖梁的施工。本文以某市政桥梁为例,结合施工实际情况提出了切实可行的水中打木桩平台施工技术方案。 In municipal bridges, some methods of construction are less economical and practical due to wider road width, smaller and longer caps, or single-pillared monopiles with softer soil. In view of this kind of single-pile single-column, the width of the road, the water depth within 4m of the bridge across the river, using into the river platform into the pile of bored piles, piers and capping beam construction. In this paper, a municipal bridge as an example, combined with the actual situation of the construction put forward a feasible platform for the construction of water piling technology program.
