Description

Technical Field

[0001] The present application relates to the technical field of environmental protection construction, and particularly relates to an automatic HDPE membrane laying device for self-setting mortar ultra-deep wall segments. Background Art

[0002] In the field of environmental protection, heavy metal pollution in groundwater caused by the stacking of industrial waste residues, leakage of leachate from domestic waste landfills leading to groundwater pollution, and the spread of soil pollution caused by oil and chemical industries in recent years, resulting in pollution of surrounding farmland and living areas. More and more pollution incidents have been exposed, leading to excessive heavy metals in river water, pollution of underground soil by landfilled organic chemical residues, and pollution of domestic water around mines, etc.

[0003] The eradication of pollution sources is not achieved overnight, but the spread of the pollution radius is increasing year by year and month by month, constantly threatening the life and survival of humans; therefore, the control of pollution sources is particularly important. The vertical flexible anti-seepage technology has gradually been applied to the control and treatment of pollution sources due to its advantages of small floor area, quick effect, and corrosion resistance.

[0004] Vertical flexible anti-seepage forms a vertical groove, and then vertically installs the HDPE membrane into the groove to block the flow of underground polluted water and prevent the spread of polluted groundwater, thereby achieving closed control of the pollution source.

[0005] Since the width of the laid HDPE membrane is limited, matching locking grooves need to be respectively arranged on both sides of the HDPE membrane so that adjacent HDPE membranes can be butted to ensure integrity; however, the locking grooves of the previously laid HDPE membrane will be blocked by mud, making it impossible for adjacent HDPE membranes to be butted, resulting in incomplete butting and leakage. Therefore, the above problems need to be solved urgently. Summary of the Invention

[0006] In view of the above defects or deficiencies in the prior art, it is desired to provide an automatic HDPE membrane laying device for self-setting mortar ultra-deep wall segments.

[0007] The present application provides an automatic HDPE membrane laying device for self-setting mortar ultra-deep wall segments, including a frame body and an HDEP roller;

[0008] The HDEP roller is rotatably installed on the frame body and is used to provide the HDEP membrane; counterweights are provided at the ends of the HDEP membrane, and locking grooves are respectively provided on both sides;

[0009] A driving component and an auxiliary component are respectively provided on the frame body corresponding to the HDEP membrane; the driving component is butted with the counterweight and is used to provide the laying power;

[0010] The auxiliary component includes a hot melt welder; the hot melt welder is installed on one side of the frame body and is used to weld the sealing film on the lock groove; a cutting knife is provided on the side of the counterweight away from the hot melt welder and is used to separate the sealing film from the lock groove.

[0011] Furthermore, a guide roller is also provided on the frame body corresponding to the HDEP film; the guide roller is rotatably installed on the frame body and is used to control the verticality of the output end of the HDEP film.

[0012] Furthermore, the guide roller is connected to the frame body through a slider; the slider is slidably installed on the frame body and is driven by a first electric cylinder; the guide roller is rotatably installed on the slider.

[0013] Furthermore, the driving component includes a second electric cylinder and a counterweight plate; the counterweight plate is connected to the second electric cylinder through a pressing steel pipe and one end abuts against the counterweight; the second electric cylinder is fixedly installed on the frame body, and the telescopic direction is parallel to the direction where the HDEP film is laid.

[0014] Furthermore, the length of the pressing steel pipe matches the stroke of the second electric cylinder, and thread male heads and thread female heads are respectively provided at both ends; after the thread male head and the thread female head are butted, a reduced diameter with a relatively small diameter is formed.

[0015] Furthermore, a docking sleeve is provided on the second electric cylinder corresponding to the pressing steel pipe; the docking sleeve is sleeved on the pressing steel pipe and is provided with clamping claws; the clamping claws are rotatably installed on the docking sleeve and are used for clamping with the reduced diameter.

[0016] Furthermore, a nozzle is also provided on the counterweight plate; the nozzle is located on the side close to the cutting knife and is connected to the outside through a hose.

[0017] Furthermore, universal wheels are also included; the universal wheels are installed at the four corners of the bottom of the frame body.

[0018] Furthermore, third electric cylinders are respectively provided on the frame body corresponding to the universal wheels; the third electric cylinders are fixedly installed on the frame body, and the telescopic direction is parallel to the direction where the HDEP film is laid.

[0019] Furthermore, stay cables are also included; the stay cables are respectively installed at the four corners of the top of the frame body and are used to connect to the ground to form a pulling force.

[0020] The advantages and positive effects of this application are:

[0021] This technical solution can effectively form a driving force by setting a driving component on the frame and cooperating with the counterweight at the end of the HDEP film, so as to ensure the normal lowering of the HDEP film; a matching sealing film and a hot melt welder are also provided in the locking groove on one side of the frame corresponding to the HDEP film. As the HDEP film is lowered, the hot melt welder will weld the sealing film on the locking groove, thereby preventing sludge from entering and causing the locking groove to be blocked; the cutting knife installed on the side of the counterweight away from the hot melt welder can effectively separate the sealing film and the locking groove. When the subsequent HDEP film is lowered, the cutting knife will first peel off the sealing film before docking, which can effectively ensure the integrity of the assembly.

Detailed Description of the Embodiment

[0026] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present application.

[0027] Please refer to Figures 1-3, this embodiment provides an automatic HDPE membrane laying device for self-setting mortar ultra-deep wall segments, including a frame body 100; a relatively rotatable HDEP roller 200 and a sealing membrane roller 321 are respectively arranged on the frame body 100; wherein the HDEP roller 200 is used to provide the laid HDEP membrane 210; and the sealing membrane roller 321 is used to provide the sealing membrane 320; at the same time, corresponding driving components and auxiliary components are respectively arranged on the frame body 100 for the HDEP membrane 210 and the sealing membrane 320.

[0028] Preferably, locking grooves 212 that match each other are respectively arranged on both sides of the HDEP membrane 210, so as to ensure that adjacent HDEP membranes 210 can be slidably butted, ensuring the integrity between the HDEP membranes 210; a relatively fixed counterweight 211 is arranged at one end of the HDEP membrane 210 away from the HDEP roller 200.

[0029] In a preferred embodiment, the driving component includes a second electric cylinder 120; the second electric cylinder 120 is fixedly installed on the frame body 100, respectively located on both sides of the HDEP membrane 210, and drives the continuous laying of the HDEP membrane 210 by pressing down the steel pipe 122.

[0030] Preferably, thread male heads and thread female heads are respectively arranged at both ends of the pressing-down steel pipe 122, and the length is the same as the telescopic length of the second electric cylinder 120; the diameter of the thread male head is relatively smaller than the diameter of the pressing-down steel pipe 122. When the thread male head is connected to the thread female head of another pressing-down steel pipe 122, a reduced diameter with a relatively smaller diameter will be formed.

[0031] Preferably, the pressing-down steel pipe 122 is butted against the HDEP membrane 210 through a counterweight plate 121; the counterweight plate 121 is respectively connected to two juxtaposed pressing-down steel pipes 122, and a matching card slot is arranged at one end away from the second electric cylinder 120 corresponding to the counterweight 211; during laying, the counterweight plate 121 can not only be clamped with the counterweight 211 to drive the HDEP membrane 210, but also provide a downward pressure through its own gravity; when the laying of the HDEP membrane 210 is completed, the counterweight plate 121 can also be separated from the counterweight 211 at any time and rise and return together with the pressing-down steel pipe 122.

[0032] Preferably, the second electric cylinder 120 is connected to the downward pressing steel pipe 122 through a docking sleeve 130; the docking sleeve 130 is sleeved on the downward pressing steel pipe 122 and fixedly connected to the piston rod of the second electric cylinder 120; at the same time, the docking sleeve 130 is also provided with clamping claws 131 corresponding to the diameter change of the downward pressing steel pipe 122; the number of the clamping claws 131 is three, evenly arranged around the docking sleeve 130 and hinged to the docking sleeve 130; a torsion spring is installed on the hinge shaft to enable the clamping claws 131 to self-reset, and at the same time, the inner side of the end of the clamping claws 131 is a bevel structure. When the docking sleeve 130 slides downward relative to the downward pressing steel pipe 122, the clamping claws 131 always hold tightly on the downward pressing steel pipe 122 until the diameter-changing position, forming a clamping connection to drive it; conversely, when the docking sleeve 130 rises relative to the downward pressing steel pipe 122, the clamping claws 131 will slide out of the diameter change through the bevel structure; therefore, in cooperation with the second electric cylinder 120, continuous driving of the HDEP film 210 can be achieved.

[0033] In a preferred embodiment, a guide roller 110 is further provided on the frame 100 corresponding to the HDEP film 210; the guide roller 110 is slidably installed on the frame 100, located between the HDEP roller 200 and the driving assembly, and is used to support the HDEP film 210 and adjust the downward angle, so as to facilitate docking with the adjacent HDEP film 210.

[0034] Preferably, the guide roller 110 is connected to the frame 100 through a slider 111; the slider 111 is rotatably installed on the frame 100 and driven by a first electric cylinder 112; the guide roller 110 is rotatably installed on the slider 111 to prevent friction with the HDEP film 210, thereby affecting the downward setting of the HDEP film 210.

[0035] In a preferred embodiment, the auxiliary assembly includes a hot melt welder 300; the hot melt welder 300 is installed on one side of the frame 100 and corresponds to the locking groove 212; the sealing film 320 is located between the locking groove 212 and the hot melt welder 300, and can be hot melt welded to the locking groove 212 after being heated by the hot melt welder 300; thus, preventing mud from entering.

[0036] Preferably, after the sealing film 320 is welded to the locking groove 212, water is injected into the locking groove 212 to ensure the pressure balance inside and outside the sealing film 320 and prevent the sealing film 320 from bursting due to pressure difference.

[0037] Preferably, a cutting knife 310 is further provided on the counterweight 211; the cutting knife 310 is fixedly installed at the end of the counterweight 211, located on the side of the HDEP film 210 away from the hot melt welder 300, and can peel the welded sealing film 320, so as to ensure that the HDEP film 210 set down again can be docked with the adjacent HDEP film 210.

[0038] Preferably, a nozzle 123 is further installed on the counterweight plate 121; the nozzle 123 is fixedly installed on the counterweight plate 121, on the side close to the cutting blade 310, and is connected to the outside through a hose; by spraying high-pressure water through the nozzle 123, the pressure caused by the mud on the sealing film 320 can be effectively solved, so as to ensure that after the cutting blade 310 cuts the sealing film 320, the sealing film 320 can smoothly disengage from the locking groove 212, thus avoiding affecting the butt joint between the HDEP films 210.

[0039] In a preferred embodiment, universal wheels 140 are further provided at the bottom of the frame body 100; the universal wheels 140 are fixedly installed at the four corners of the frame body 100, so that the frame body 100 can still be moved to the designated position without the aid of peripheral equipment.

[0040] Preferably, third electric cylinders 141 are respectively provided corresponding to the universal wheels 140 at the four corners of the frame body 100; the third electric cylinders 141 are fixedly installed on the frame body 100, and a floor anchor is installed on the piston rod. After being fully extended and retracted, the frame body 100 can be lifted as a whole, so that the universal wheels 140 are separated from the ground, preventing the frame body 100 from moving again.

[0041] Preferably, the four third electric cylinders 141 are respectively linked with an inclination sensor; the inclination sensor is fixedly installed on the frame body. By controlling the four third electric cylinders 141, it can be ensured that the frame body 100 is in a horizontal state, thereby further ensuring that the HDEP film 210 can be vertically lowered.

[0042] Preferably, stay cables 150 are further installed on the frame body 100; the stay cables 150 are respectively installed at the four corners of the top of the frame body 100. By connecting to the ground, a pulling force is formed, so as to offset the reverse force generated by the lowering of the HDEP film 210.
