Description

Technical Field

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

[0002] At present, anti-seepage construction is the most important link in the construction process of reservoirs. It is the key to ensure the overall stability of the reservoir and prevent water seepage accidents. The common anti-seepage structural layer is a geomembrane laid on the water-facing surface and the entire bottom of the reservoir, such as HDPE (high-density polyethylene) membrane. The weight of common geomembranes is 0.94-0.98kg / ㎡. The width of geomembranes used in reservoir construction is 6-8m, the length is 50m / roll, and the weight of the whole roll is 282-294kg. Manual laying is difficult and inefficient, especially when laying geomembranes on slopes. The laying difficulty and construction quality are difficult to meet the construction requirements, and there is a lack of automated machinery for laying geomembranes on slopes.

[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 by its own weight to achieve laying. When using this laying method, the geomembrane roll will roll down the slope due to its own weight. The acceleration along the slope 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, so that the originally tightened geomembrane will be subjected to tensile stress exceeding its own limit and be torn off, resulting in seepage points, posing a major safety hazard.

[0004] Existing geomembrane laying machinery can be roughly divided into two categories: one type of machinery is for agricultural geomembranes with small weight and narrow width, but is not suitable for engineering geomembranes with large width and weight, and cannot be used on slopes; the other type of slope covering equipment is based on laying tracks at the bottom and top of the slope, setting up support frames parallel to the slope on the tracks, and hanging rolls of geomembranes for laying. This type of equipment requires customized support frames and slides for different slopes, and the tracks need to be frequently installed and removed, which is inefficient. In addition, the construction base of the geomembrane for the dam is soil, which is not suitable for slide installation. Summary of the invention

[0032] A method for automatically laying a geomembrane on a slope is provided, which uses an automatic geomembrane laying machine for laying the geomembrane on a slope, and comprises the following steps: Step 1: Install the base 1 and the power device on the top of the slope or on the 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; 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.

[0033] In the present invention, step one includes: a staff member installs the base 1 and the motor 4 on the top of the slope or on the vehicle, the staff member pushes the sliding seat 12 to move along the slide groove, 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.

[0034] In the present invention, step 2 includes: turning on the automatic clamp 17 through the controller, the staff clamps 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 is in contact with the geomembrane roll 30, the geomembrane roll 30 rotates, the rotating shaft 1 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.
