Double-wall steel cofferdam floating transportation positioning sinking construction method with pile foundation first and cofferdam later
The invention relates to the technical field of cofferdam construction, and particularly relates to a double-wall steel cofferdam floating transportation positioning sinking construction method with a pile foundation first and a cofferdam later. The method comprises the following steps that S1, a construction steel trestle and a floating platform are built, and a bottom section cofferdam is assembled on the floating platform; S2, water is injected into a floating box to enable the floating box to sink until the bottom section cofferdam floats in the water, and other sections of cofferdam on the upper portion are assembled on the bottom section cofferdam; S3, pile foundation steel casing underwater cutting and positioning steel casing inserting and beating are carried out at the pier position; S4, the assembled double-wall steel cofferdam is transported to the pile foundation steel casing in a floating mode; S5, the double-wall steel cofferdam is positioned, sunk and leveled; and S6, foundation cleaning and bottom sealing are carried out in the double-wall steel cofferdam, and a bearing platform and a pier body are constructed. According to the construction method, the double-wall steel cofferdam assembling and the pile foundation synchronous construction can be realized, the large occupation of the cofferdam assembling on the construction period is avoided, the cofferdam construction period is effectively shortened, and sufficient construction period storage is provided for subsequent construction of the bearing platform, the pier body and the like.
本发明涉及围堰施工技术领域，具体涉及一种先桩基后围堰的双壁钢围堰浮运定位下沉施工方法，包括以下步骤：S1.搭建施工钢栈桥和浮平台；在浮平台上拼装底节围堰；S2.对浮箱注水使其下沉，直至底节围堰在水中自浮；在底节围堰上完成上部其他节段围堰拼装；S3.在墩位处进行桩基钢护筒水下切割及定位钢护筒插打；S4.将已拼装完成的双壁钢围堰浮运至桩基钢护筒处；S5.进行双壁钢围堰定位下沉并调平；S6.进行双壁钢围堰内清基封底，施工承台和墩身。本发明的施工方法可实现双壁钢围堰拼装和桩基的同步施工，避免了围堰拼装对工期的大量占用，有效缩短围堰施工工期，为后续承台、墩身及其他施工提供充足的工期的储备。
