Underwater dismantling method for steel-concrete structure of steel cofferdam
The invention discloses an underwater dismantling method for a steel-concrete structure of a steel cofferdam. The construction method comprises the following steps. The method comprises the steps of 1, construction preparation; 2, main equipment is prepared, wherein a hydraulic rope sawing machine and a floating crane are prepared; 3, the steel-concrete structure is subjected to blocking operation; 4, a wire saw is installed; 5, steel and concrete dismantling operation is carried out; step 6, realizing cut object treatment operation; and step 7, performing underwater operation construction operation by the diver. The method has the following construction characteristics that the method is not limited by the size and the shape of a cut object, and a large reinforced concrete structure can be cut and dismantled; the cutting speed is high, a notch is straight, subsequent procedures are not needed, and a building structure is not damaged; cutting in any direction, such as the transverse direction, the vertical direction and the diagonal direction, can be realized; and the construction period can be shortened through rapid cutting. The cutting efficiency is about 2.2 m < 2 >/h; and the cutting process can be remotely controlled.
本发明公开了一种钢围堰钢混结构水下拆除方法；施工方法流程如下；步骤1，施工准备；步骤2，主要设备准备，包括液压绳锯机及浮吊的准备；步骤3，钢混结构进行分块操作；步骤4，进行绳锯机安装操作；步骤5，进行钢混拆除操作；步骤6，实现切割物处理操作；步骤7，潜水员水下作业施工操作。具有如下施工特点：不受被切割物体积大小和形状的限制，能切割和拆除大型的钢筋混凝土构筑物；切割速度快，切口平直，无须后续工序，对建筑物结构无损伤；可以实现任意方向的切割，如横向、竖向、对角线方向等；快速的切割可以缩短工期。切割效率：2.2㎡/h左右；可远距离控制切割过程。
