Geotextile tube positioning method

The invention discloses a geotextile tube positioning method which includes the following steps that 1, holes are formed in a geotextile tube in the length direction at intervals, a rope penetrates through the holes and is tied to a control rod, and the geotextile tube is hoisted and transferred to a breakwater construction position through the control rod; 2, a sand filling port of the geotextile tube is connected with a sand filling pipeline; 3, the geotextile tube is pressed to the construction position by pressing the control rod, the periphery of the geotextile tube is assisted by the rope to be fixed in a traction and pulling mode, the geotextile tube is kept to be located above the water surface, and the sand filling port is downward; 4, pressing for the control rod is eased in the sand filling process, traction of the rope is eased, the control rod is released when the geotextile tube can keep stable in water, and the rope assisting in traction and pulling is cut off so that the geotextile tube can slide off and roll to a target position in the water. The method has the advantages of being easy to operate, high in construction efficiency and accurate in positioning.
