Construction method of double-wall steel hanging box cofferdam serving as drilling platform
The invention relates to a construction method of a double-wall steel hanging box cofferdam concurrently serving as a drilling platform, and belongs to the technical field of cofferdam construction.The construction method comprises the following steps that firstly, a cofferdam is assembled, a fixing assembly is arranged in the cofferdam, and a positioning steel casing is installed in the fixing assembly; secondly, a first positioner is inserted into the center of the target position of the positioning steel casing, a second positioner is arranged in the positioning steel casing, the first positioner and the second positioner are aligned, and after alignment, the cofferdam and a shore fixing pile are connected through an anchor cable; thirdly, the fixing assembly keeps fixing the positioning steel casing in the horizontal direction, the second positioner is removed, and the positioning steel casing is inserted and hit through the floating crane; fourthly, the cofferdam is made to sink and sealed, and the interior of the cofferdam is isolated from the exterior of the cofferdam; the cofferdam positioning device has the characteristic of high cofferdam positioning efficiency.
本发明涉及一种兼做钻孔平台的双壁钢吊箱围堰施工方法，属于围堰施工技术领域，包括下列步骤：步骤一：进行围堰的拼装，并在所述围堰中设置固定组件，在所述固定组件内安装定位钢护筒；步骤二：在所述定位钢护筒目标位置中心处插下第一定位器，在所述定位钢护筒内设置第二定位器，使第一定位器和第二定位器对齐，对齐后利用锚索将围堰与岸上固定桩连接；步骤三：所述固定组件保持对定位钢护筒在水平方向上的固定，将第二定位器移除，利用浮吊插打定位钢护筒；步骤四：使围堰下沉，并进行密封，使围堰内部和外部隔绝；其具有围堰定位效率高的特点。
