[0002] High-density polyethylene self-adhesive geomembrane is a type of geomembrane. High-density polyethylene self-adhesive geomembrane (HDPE self-adhesive geomembrane) is a composite geotechnical material that combines high-density polyethylene (HDPE) geomembrane with self-adhesive technology.

[0003] In construction projects, groundwater is susceptible to contaminants, such as hazardous substances and wastewater from landfills. Installing geomembranes can effectively prevent these pollutants from seeping into groundwater, thereby protecting the safety and cleanliness of groundwater resources. This role is particularly important in sites like landfills and sewage treatment plants. In infrastructure construction, such as municipal roads and highways, geomembranes can prevent penetration and infiltration of foundation soil, reduce the risk of foundation settlement, and improve road stability and safety. The installation of geomembranes is crucial for environmental protection, project safety, agricultural production, and economic benefits. In practical applications, the appropriate geomembrane material and installation method should be selected based on the specific project requirements and conditions to fully leverage its advantages and benefits.

[0004] The utility model patent with application number: CN202322678394.3 and publication number: CN221026784U (hereinafter referred to as "prior art 1") discloses a geomembrane laying auxiliary device, which includes a mounting plate and a walking member arranged on the bottom surface of the mounting plate. The mounting plate moves on the reservoir ground through the walking member. A pushing assembly is provided on the mounting plate, and the pushing assembly is used to push the geomembrane roll to rotate on the ground. The pushing assembly includes a pushing plate arranged on the mounting plate, and the pushing plate is used to abut against the geomembrane roll.

[0005] The specification of prior art 1 discloses a geomembrane laying auxiliary device. When in use, the geomembrane roll is first placed on the bottom surface of the reservoir, so that one end of the geomembrane on the geomembrane roll is fixed on the ground, and then the roller is abutted against the laid geomembrane, and the pushing plate and the geomembrane roll are abutted at the same time. The staff pushes the installation plate through the handle, and the installation plate drives the pushing plate to move, and the pushing plate pushes the geomembrane roll to rotate on the ground, thereby laying the geomembrane on the geomembrane roll on the bottom surface of the reservoir. However, in actual application, since the size of the pushing plate is fixed, the radius of the geomembrane roll will become smaller and smaller as the geomembrane roll is laid, so that the pushing plate changes from surface contact at the starting position to point contact, which makes the pushing plate unable to stably lay the geomembrane roll.

DETAILED DESCRIPTION

[0027] The present invention is further described below with reference to the embodiments. The embodiments described are only a portion of the embodiments of the present invention and are not intended to be all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by persons of ordinary skill in the art without creative effort are also within the scope of protection of the present invention.

[0028] See also Figure 1-3 As shown, this embodiment discloses a geomembrane laying structure, specifically a high-density polyethylene self-adhesive geomembrane laying structure, including a fixing device and a laying device, the fixing device is used to fix the geomembrane body 101, and the laying device is used to lay the geomembrane body 101 while moving on the ground;

[0029] The fixing device includes a support frame 102, a winding roller 103, a tensioning assembly and a pressing assembly. The support frame 102 is used to be fixed on the ground. The winding roller 103 is rotatably installed on the support frame 102 and is used to reel the geomembrane body 101. The tensioning assembly and the pressing assembly are installed on the support frame 102. The tensioning assembly is used to tension the geomembrane body 101, and the pressing assembly is used to fix the geomembrane body 101.

[0030] The laying device includes a mobile body 104 and a clamping assembly. The mobile body 104 is used to move on the ground. The clamping assembly is installed on the mobile body 104. The clamping assembly is used to clamp and fix the end of the geomembrane body 101.

[0031] In actual use of the present invention, the staff installs the rolled-up geomembrane body 101 and the winding roller 103 on the support frame 102, and then pulls out the end of the geomembrane body 101, so that the geomembrane body 101 passes through the compression assembly and the tensioning assembly in sequence and is finally fixed to the bottom of the mobile vehicle 104. Then, the position of the compression assembly is adjusted, the compression assembly and the support frame 102 are fixed to the ground, and the mobile vehicle 104 is pulled. When the mobile vehicle 104 moves on the ground, the geomembrane body 101 is pulled. At this time, the geomembrane body 101 is released by the winding roller 103 until the geomembrane body 101 completely covers the area to be covered, and then stops. The mobile body 104 is moved, and finally the end of the geomembrane body 101 is removed from the mobile body 104, and the geomembrane body 101 is fixed on the ground; when the geomembrane body 101 is recycled, it is only necessary to disengage the geomembrane body 101 from the ground, and then wind up the winding roller 103, and rewind the geomembrane body 101 on the winding roller 103; the advantage of this arrangement is that the geomembrane body 101 can be laid stably by the movement and pulling of the mobile body 104, and the geomembrane body 101 can also be recycled by the rotation of the winding roller 103; the geomembrane body 101 is more stable during laying and more convenient during recycling.

[0032] In some embodiments, the tensioning assembly includes a mounting rod 105 and a tensioning roller 106. There are two mounting rods 105, and the two mounting rods 105 are arranged on the support frame 102. The two ends of the tensioning roller 106 are respectively rotatably installed on the two mounting rods 105. The geomembrane body 101 is used to contact the tensioning roller 106 after passing through the compression assembly.

[0033] During actual use, the tensioning roller 106 can rotate on the two mounting rods 105. When the geomembrane body 101 is laid or recovered, the rotation of the tensioning roller 106 can reduce the friction between the geomembrane body 101 and the tensioning roller 106, and the tensioning roller 106 can always play a role in tensioning and pressing the geomembrane body 101.

[0034] In some embodiments, the compression assembly includes a crank 107, a compression roller 108 and a ground anchor 109. There are two cranks 107, and both cranks 107 are connected to the support frame 102 for damping rotation. The compression roller 108 is rotatably installed between the two cranks 107, and the ground anchor 109 is rotatably installed on the crank 107. The ground anchor 109 is used to fix the position of the crank 107 after being inserted under the ground, and the geomembrane body 101 is used to be wound on the compression roller 108.

[0035] During actual use, the staff needs to adjust the inclination angle of the crank 107, so that the compression roller 108 and the tensioning roller 106 cooperate to tension the geomembrane body 101, and finally use the ground film to fix the position of the compression roller 108 to prevent the geomembrane body 101 from changing the inclination angle of the crank 107 when pulling.

[0036] In some embodiments, the crank 107 is rotationally engaged with the support frame 102 via a sliding protrusion 110 . A sliding recess 111 is provided on the support frame 102 , and the sliding protrusion 110 is used to be slidably installed in the sliding recess 111 .

[0037] During actual use, the sliding protrusion and the sliding recess 111 are matched with damped sliding. A large force is required to slide between the sliding protrusion and the sliding recess 111. The purpose of damped sliding is to prevent the angle of the crank 107 from changing when laying the geomembrane body 101. Since the force of the geomembrane body 101 itself is relatively small when it is pulled, after damped sliding, relative sliding cannot occur between the sliding protrusion and the sliding recess 111 when laying or recovering the geomembrane body 101. The advantage of this setting is that it is easy to adjust the angle of the crank 107.

[0038] In some embodiments, the clamping assembly includes a U-shaped fixing plate 112 and a sliding pressure plate 113. The U-shaped fixing plate 112 is installed under the mobile body 104, and the sliding pressure plate 113 is slidably installed on the U-shaped fixing plate 112. A threaded hole is provided on the mobile body 104, and a bolt 114 is provided in the threaded hole. The end of the bolt 114 is rotatably connected to the sliding pressure plate 113.

[0039] During actual use, when the geomembrane body 101 needs to be fixed, the staff places the geomembrane body 101 on the U-shaped fixing plate 112, and then turns the bolt 114. As the bolt 114 rotates, the sliding pressure plate 113 moves toward the U-shaped fixing plate 112, and finally the sliding pressure plate 113 fixes the geomembrane body 101 on the U-shaped fixing plate 112.

[0040] In some embodiments, a guide hole is further provided on the mobile body 104 , and a guide rod 115 is slidably provided in the guide hole, and an end of the guide rod 115 is fixedly connected to the sliding pressure plate 113 .

[0041] In actual use, the purpose of providing the guide hole is to make the sliding pressure plate 113 more stable when sliding.

[0042] In some embodiments, a pulling handle 116 is provided on the mobile body 104 .

[0043] During actual use, the staff drags the push-pull handle Genori to move the mobile body 104. The provision of the pulling handle 116 enables the staff to move the mobile body 104 more labor-savingly.

[0044] In some embodiments, the bottom of the mobile body 104 has a plurality of rollers 117 .

[0045] During actual use, the mobile body 104 moves relative to the ground via the plurality of rollers 117 .

[0046] In some embodiments, a leveling device is provided at the bottom of the mobile vehicle 104 , and the leveling device is used to level the angle of the geomembrane body 101 .

[0047] In actual use, the function of the leveling device is to ensure that the geomembrane body 101 remains flat after the wet mobile vehicle body 104 moves away from the support frame 102 .

[0048] In some embodiments, the leveling device includes a rotating part 118 and a leveling roller 119. There are two rotating parts 118, and the two rotating parts 118 are fixedly installed under the mobile body 104. The leveling roller 119 is rotatably installed between the two rotating parts 118, and the geomembrane body 101 is used to contact the leveling roller 119.

[0049] During actual use, the geomembrane body 101 is released by the winding roller 103, passes through the pressing roller 108, the tensioning roller 106 and the leveling roller 119 in sequence, and is finally fixed by the sliding pressure plate 113. After the geomembrane body 101 contacts the leveling roller 119, the geomembrane body 101 can remain flat.
