Cofferdam method for bearing platform
The invention discloses a cofferdam method for a bearing platform. The cofferdam method comprises the following steps of pile driving, wherein a plurality of pile foundation pile casings are inserted into the ground from the river bottom; and a plurality of main beams are installed on the tops of the pile foundation protection cylinders correspondingly, and perforating jacks are installed on the main beams correspondingly and connected with lifting threaded rods correspondingly. And building a construction platform. And an inner supporting assembly is built. And lowering the sub-assembly body. And repeating the step of lowering the sub-assembly. And a board inserting step. The requirement for the rigidity of the inner supporting assembly can be lowered, and it is guaranteed that the inner supporting assembly has enough strength after being installed. And moreover, ship hoisting is not needed, so that a series of problems caused by ship hoisting are avoided.
本发明公开了一种用于承台的围堰方法，包括以下步骤：打桩步骤：将多根桩基护筒从河底插入地底下；将多个主梁分别安装在各桩基护筒的顶部，并在各主梁上分别安装有穿孔千斤顶，各穿孔千斤顶均连接有升降螺纹杆。搭建施工平台步骤。搭建内撑组件步骤。下放子装配体步骤。重复下放子装配体步骤。插板步骤。其能够降低对内撑组件的刚度要求，以及保障内撑组件安装后具备足够的强度；而且，无需采用船舶吊装，从而避免因采用船舶吊装而引发的一系列难题。
