[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Please refer to Figure 1-6 A double-layer geotextile laying device comprises a hull 1 (the main function of the positioning ship is to accurately position the geotextile laying buoy and operate the platform, which is mainly composed of a hull, a control room, a GPS antenna, a radio antenna, an anchor windlass, a generator, etc. These parts are all existing technologies and will not be repeated here). A buoy 2 is provided on the front side of the hull 1, and a plurality of sandbags 3 are fixedly installed on the top of the buoy 2 near the rear side. A supporting frame 4 is provided on the top of the buoy 2 near the front side. Two winch bodies 5 are fixedly installed on the top of the hull 1 near one side. The winch bodies 5 are arranged on the left and right, and steel ropes 7 are installed on the winch bodies 5. Two inclined rods 6 are provided on the top of the hull 1 near one side, and a cross bar 8 is fixedly installed on the bottom end of the steel rope 7. The geotextile can be laid on a slope containing water, thereby reducing the cost of laying the geotextile and improving the laying efficiency.

[0023] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 One side of the support frame 4 movably passes through the movable rod 16, and both ends of the movable rod 16 are rotatably connected to the vertical plate 15. The bottom of the vertical plate 15 is fixedly connected to the top of the buoy 2, which can support the geotextile when it is unrolled.

[0024] A support seat 9 is fixedly installed on the rear side of the diagonal rod 6, and the bottom of the support seat 9 is fixedly connected to the top of the hull 1. L-shaped brackets 10 are fixedly installed on both sides of the diagonal rod 6 near the middle position, and the bottom of the L-shaped bracket 10 is fixedly connected to the buoy 2. By setting the support seat 9 and the L-shaped bracket 10, the diagonal rod 6 can be supported.

[0025] A rectangular opening 11 is provided on the front side of the inclined rod 6, and the inner cavity side walls of the rectangular opening 11 are rotatably connected to a rotating shaft 13. A pulley 12 is fixedly sleeved on the outer periphery of the rotating shaft 13 near the middle position, and the pulley 12 can support the steel rope 7.

[0026] A limiting annular groove 14 is provided at the middle position of the outer circumference of the pulley 12, and the outer circumference of the steel rope 7 is located in the inner cavity of the limiting annular groove 14, and the steel rope 7 can be limited by the limiting annular groove 14 provided on the pulley 12.

[0027] Working principle: 1. The geotextile is manually spread on the buoy 2, and the land end is fixed with sandbags (the number of sandbags is 1 bag / m).

[0028] 2. Use the winch body 5 to place the crossbar 8 into the water and keep the pressure bar 2m-2.5m underwater at all times, and adjust the remaining geotextile on the buoy 2 to make it smooth and wrinkle-free.

[0029] 3. According to the geotextile laying grid diagram, slowly move the positioning boat 1 and the pontoon 2 away from the shore. When laying the geotextile on the water, use the onboard detection system to reflect the geotextile laying trajectory. If there is any deviation, make adjustments immediately. The step distance of each boat movement is 4m. The geotextile is dragged by manpower to make it move slowly with the hull 1, and a small amount of half bricks are thrown from the pontoon 2 to the geotextile unfolded in the water for ballasting, so that the geotextile sinks to the bottom of the water and fits the slope. A 3m area is reserved at the overlap between the current geotextile and the next geotextile without throwing half bricks, and half bricks are thrown after the next geotextile is laid. If the water flow is too strong and the geotextile may float on both sides, sandbags 3 need to be thrown in time for ballasting.

[0030] 4. When there is 4m left in the laying of geotextile, stop moving the boat, wrap the end of the geotextile with sandbag 3 and tie nylon ropes with a certain length exceeding the water depth at both ends of the geotextile to ensure that after moving the boat for the last 4m, the drift of the geotextile can be controlled by the nylon ropes on both sides so that the geotextile at this elevation can better fit and fix to the slope.
