Combined cofferdam construction method under hard riverbed
The invention is applicable to the technical field of riverbed cofferdam construction, and provides a combined cofferdam construction method under a hard riverbed. The method comprises the following steps of Step 1, construction preparation; Step 2, island filling and pile foundation construction; Step 3, guide hole construction; Step 4, steel pipe pile and steel sheet pile insertion and driving; Step 5, foundation pit excavation and surrounding sandalwood support installation; Step 6, foundation pit excavation to the preset elevation; Step 7, bearing platform pier body construction and foundation pit backfilling; and Step 8, surrounding sandalwood inner support dismounting, and steel pipe pile and steel sheet pile pulling removal. According to the method, cofferdam construction can be performed on the hard riverbed, the occlusion type hole guiding operation is not needed, the problem that hole staggering can easily occur in the hole guiding process is solved, the construction speed is high, the safety is high, and the application range is wide.
本发明适用于河床围堰施工技术领域，提供了一种坚硬河床下组合式围堰施工方法，所述方法包括步骤：S1、施工准备；S2、对筑岛填筑和桩基施工；S3、进行引孔施工；S4、插打钢管桩及钢板桩；S5、对基坑开挖及围檀支撑安装；S6、通过对所述基坑开挖至预设的标高；S7、对承台墩身施工及所述基坑回填；S8、对所述围檀内撑拆除，并对所述钢管桩和所述钢板桩拔除。本发明能够在坚硬的河床进行围堰施工，无需咬合式引孔作业，避免了引孔过程中容易出现串孔的问题，施工速度快，安全性高，使用范围广。
