The invention provides a positioning method of a rotary excavating drilling and floating platform, which comprises the following steps of: moving a workboat to a construction position, and throwing a positioning anchor for preliminary positioning; re-positioning by using a core-pulling anchor; the shore side of the floating platform is fixed through the mooring rope and the anchor rod, and the river side is anchored and fixed through the mooring rope; by means of the sensor and the controller, when the water level mode changes, the control system adjusts the positioning anchor, the core-pulling anchor and the mooring rope, so that the plane position of the floating platform is fixed, and the mooring rope is in a stressed tightening state all the time. The floating platform positioning device can solve the problem of floating platform positioning, can meet the requirement of the rotary drilling rig for resisting torque generated by rotary drilling, is wide in application range, and can be applied to positioning of all rotary drilling rig overwater construction floating platforms.

    本发明提供了旋挖钻浮平台的定位方法,包括以下步骤,移动施工船至施工位置,抛设定位锚进行初步定位;利用抽芯锚进行再次定位;通过缆绳和锚杆对浮平台岸侧进行固定,而江侧则通过缆绳抛锚固定;利用传感器以及控制器,在水位方式变化时,控制系统调整定位锚和抽芯锚以及缆绳,使得浮平台平面位置固定,且缆绳始终处于受力收紧状态。本发明可以解决浮平台定位的同时,还可以满足旋挖钻机钻孔作业需要抵抗旋挖钻孔产生的扭矩,且适用范围广,可应用于所有旋挖钻水上施工浮平台定位。
