摘要
以昌赣客专赣州赣江特大桥36#主墩水中基础施工为工程背景,介绍在深水裸岩地质条件下采用锁扣钢管与混凝土组合桩围堰施工工艺,详细介绍了组合围堰的设计、内力计算、施工安全质量控制要点等,此组合围堰的成功产生了良好的社会效益,具有广泛的应用前景和推广价值。
Taking the No. 36 main pier foundation construction in water of Ganjiang River Bridge on Nanchang-Ganzhou High-speed Railway as the background, the paper introduces the construction technology of lock catch steel pipe and concrete composite pile cofferdam under the condition of deep water and bare rock geology. The design, internal force calculation, construction safety and quality control points of the combination-cofferdam are introduced in detail. The success of the combination-cofferdam brings good social benefits, which has a wide application prospect and popularization value.
