Method for quickly detaching high-pile mass concrete bearing platform in water

The invention provides a method for quickly detaching a high-pile mass concrete bearing platform in water. The method includes the following steps that a floating crane is in position; the bearing platform is equally divided into concrete blocks in the proper size and scribed and marked; one end of a steel wire rope penetrates through a reserved hole A of one to-be-lifted concrete block and is fixed to a limiting device below the to-be-lifted concrete block, and the to-be-lifted concrete block is lifted through the floating crane; a wire saw cutting machine is installed; and the to-be-lifted concrete block is cut off and lifted by the floating crane to be transferred to a transfer ship. By the adoption of the method, the detaching speed is high, and the safety coefficient is high. 本发明提供了种水中高桩大体积混凝土承台快速拆除方法，包括以下步骤：船吊就位；将承台等分成合适大小的混凝土块并画线标记；用钢丝绳端穿过待吊装的混凝土块的预留孔A，并与混凝土块下方的限位装置固定在起，用船吊起吊；绳锯切割机安装；将待吊装的混凝土块切割下来，船吊吊起转放到转运船上。本发明拆除速度快，安全系数高。
