摘要
为了满足挡土支护需要而设计制作了新型围护桩——先张法预应力混凝土U型板桩(以下简称U型混凝土板桩),U型混凝土板桩相比于传统的钻孔灌注桩具有质量可靠、施工方便快速、成本低廉和施工过程无污染等显著特点。重点介绍了在不同情况下的U型混凝土板桩沉桩施工方法及工艺流程。
Pre-tensioned prestressed concrete U-shaped sheet pile is designed in order to meet retaining support requirement（ hereinafter referred to as U-shaped concrete sheet pile）,which has some advantages in comparison to traditional bored pile,including reliable quality,convenient and fast construction,low cost,no pollution in construction. This paper introduces the construction method and construction process of pile driving of U-shaped concrete sheet piles under different conditions in detail.
