Description

Technical Field

[0001] The invention belongs to the technical field of slope geomembrane laying, and particularly relates to an automatic slope geomembrane laying machine and a laying method thereof. Background Art

[0002] Currently, anti-seepage construction is the most critical step in reservoir construction, crucial for ensuring the overall stability of the reservoir and preventing water seepage accidents. A common anti-seepage structural layer is a geomembrane, such as HDPE (high-density polyethylene), laid across the entire surface of the reservoir, including the water-facing surface and the bottom. Typical geomembranes weigh 0.94-0.98 kg / m2. Geomembranes used in reservoir construction are 6-8 meters wide, 50 meters long per roll, and weigh 282-294 kg per roll. Manual geomembrane installation is difficult and inefficient, especially when laying geomembranes on slopes. The difficulty and quality of installation are insufficient to meet construction requirements, and automated machinery for geomembrane installation on slopes is lacking.

[0003] In the existing construction method, the manual laying method of geomembrane on the slope of the dam is: a whole roll of geomembrane is placed on the top of the slope, and 4-5 workers rely on their own weight to step on the end of the geomembrane with their feet, so that the whole roll of geomembrane can freely roll down the slope and unfold under its own weight to achieve laying. Using this laying method, the geomembrane roll will generate an acceleration downward along the slope due to its own weight during the process of rolling down the slope, which will pull the unfolded geomembrane, so that the geomembrane is tightened after laying, and tensile stress is generated inside. Especially at the intersection of the slope foot and the reservoir bottom, after water is stored, the reservoir bottom will produce uneven settlement relative to the dam under the action of water pressure, causing the originally tightened geomembrane to be subjected to tensile stress exceeding its own limit and be torn apart, resulting in seepage points, posing a major safety hazard.

[0004] Existing geomembrane laying machinery can be roughly divided into two categories: one type is designed for lightweight, narrow agricultural geomembranes and is not suitable for large, heavy engineering geomembranes, nor can it be used on slopes. The other type of slope covering equipment uses tracks laid at the bottom and top of the slope, on which support frames parallel to the slope are erected, from which rolls of geomembrane are suspended for laying. This type of equipment requires customized support frames and slides for different slopes, requiring frequent track installation and removal, resulting in low efficiency. Furthermore, the soil base of the geomembrane surrounding the dam is not suitable for slide installation. Summary of the Invention

[0047] A method for automatically laying a geomembrane on a slope is provided, which utilizes an automatic geomembrane laying machine for laying the geomembrane on a slope, and comprises the following steps:

[0048] Step 1: Install the base 1 and the power device on the top of the slope or on a vehicle, adjust the position of the limiting device 2, and place the geomembrane roll 30 between the limiting device 1 and the limiting device 2;

[0049] Step 2: Turn on the power device, and the geomembrane will slide down the slope by automatic gravity. When the end of the geomembrane slides to the bottom of the slope, the laying of the geomembrane on the slope is completed.

[0050] In the present invention, step one includes: a staff member installs the base 1 and the motor 14 on the top of the slope or on the vehicle, the staff member pushes the sliding seat 12 to move along the slide, opens the cylinder 10, the cylinder 10 pushes the bearing 23, adjusts the position of the rotating shaft 3 8, closes the cylinder 10, and another staff member contacts the geomembrane roll 30 with the rotating shaft 5 20, the rotating shaft 3 8 and the rotating shaft 7 22, opens the cylinder 2 14, the cylinder 2 14 pushes the bearing 3 28, adjusts the position of the rotating shaft 6 21, and makes the rotating shaft 6 21 contact with the geomembrane roll 30.

[0051] In the present invention, step 2 includes: turning on the automatic clamp 17 through the controller, the staff clamping the automatic clamp 17 with the end of the geomembrane roll 30, turning on the motor 14, making the motor 14 forward, the motor 14 drives the rotating shaft 4 19 to rotate, the rotating shaft 4 19 drives the rotating shaft 5 20 to rotate, the rotating shaft 5 20 drives the rotating shaft 2 5 to rotate, the rotating shaft 2 5 drives the rotating shaft 1 2 to rotate, because the rotating shaft 5 20 contacts the geomembrane roll 30, so that the geomembrane roll 30 rotates, the rotating shaft 2 drives the rope member to rotate, so that the geomembrane roll 30 It slides down to the bottom of the slope synchronously with the automatic clamp 17. During the sliding of the geomembrane roll 30, the rotating shaft 6 21 rotates in the bearing 3 28, the rotating shaft 7 22 rotates in the bearing 4 29, and the rotating shaft 3 8 rotates in the rotating shaft 3 8.

[0052] In the present invention, after the laying of the slope geomembrane is completed, the automatic clamp 17 is closed by the controller, the motor 14 is turned on, and the motor 14 is reversed. The motor 14 drives the rotating shaft 4 19 to rotate. Due to the internal meshing ratchet 31, the internal meshing ratchet 31 does not drive the rotating shaft 5 20 to rotate, but drives the pulley 2 11 to rotate. The pulley 2 11 drives the pulley 1 6 to rotate, thereby rotating the rotating shaft 2 and retracting the automatic clamp 17.
