Secondary bottom sealing construction method for deep sea widened bearing platform cofferdam
The invention relates to the technical field of bridge engineering construction, and discloses a deep sea widened bearing platform cofferdam secondary bottom sealing construction method which comprises the following steps: step 1, collecting soil of a riverbed through equipment for analysis, and determining the depth of a sheet pile to be driven so as to meet the overall load; secondly, a plurality of guide columns are driven into a riverbed around the old pile foundation through equipment, so that a cofferdam is formed; thirdly, a plurality of sheet piles are driven into the riverbed in the mode that the two sides are diagonally opposite through equipment, the sheet piles are located on the inner sides of the guide columns and make contact with the guide columns, and then the sheet piles are gradually supplemented to the periphery and closed to form an external cofferdam with the guide columns; and fourthly, after the external cofferdam is built, water in the external cofferdam is pumped through equipment. The method has the advantages that secondary cofferdam bottom sealing can be conducted on the old bearing platform, the old bearing platform can be reinforced and maintained conveniently, the overall strength and waterproof performance of the bearing platform are improved, and therefore the service life of the bearing platform can be prolonged.
本发明涉及桥梁工程施工技术领域，公开了一种深海拼宽承台围堰二次封底施工方法，包括以下步骤：步骤一：通过设备采取河床的土壤进行分析并确定板桩需要打的深度，以满足整体负重；步骤二：通过设备将多根导向柱围绕老桩基打入河床，致使形成围堰；步骤三：通过设备将多个板桩以两边对角的方式打入河床，所述板桩位于导向柱的内侧并导向柱接触，然后逐渐向四周补齐板桩并闭合与多根导向柱组成外部围堰；步骤四：外部围堰搭设完成后，通过设备抽取外部围堰内的水。本发明可对老承台进行围堰二次封底，便于对老承台进行加固维护，提高承台的整体强度和防水性能，从而可以延长其使用寿命的优点。
