Description

Technical Field

[0001] This invention belongs to the field of geomembrane anchoring deformation technology, and more specifically, relates to a geomembrane tension adjustment and anchoring deformation monitoring and control device and monitoring method. Background Technology

[0002] As a key component of geomembrane structures, the anchoring system reliably connects the membrane material to surrounding structures (such as concrete foundations, anchoring trenches, or adjacent geosynthetics). The stability of the anchoring structure directly determines the overall performance of the seepage prevention system. Excessive deformation or failure in the anchoring zone may lead to membrane tearing, interface slippage, or stress concentration, thereby causing leakage or even engineering disasters.

[0003] Currently, commonly used anchoring methods in engineering include concrete anchoring trenches, mechanical anchoring (such as anchor bolts and pressure strips), and soil covering anchoring. However, these geomembrane anchoring methods currently have the following problems: 1. Temperature changes can affect the interfacial friction angle between the geomembrane and the subbase material. For example, increased temperature will increase the cohesion between the membrane and the interfacial material, but long-term exposure may accelerate material aging and reduce anchoring durability.

[0004] 2. HDPE membranes are prone to creep under long-term loads, which leads to the gradual release of stress at the anchoring ends, resulting in membrane loosening or localized stretching and thinning, especially in steep slopes or high-stress areas.

[0005] 3. Deformation in the anchorage zone is concealed, making it difficult for traditional strain gauges to achieve long-term distributed monitoring, and there is a lack of widespread application of intelligent early warning systems (such as fiber optic sensing).

[0006] 4. The current anchoring methods are not well adapted to steep slopes and complex terrain, and cannot play their due anchoring role under strong earthquake and strong wind loads.

[0007] Therefore, how to provide a device for controlling the deformation of geomembrane anchorage is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0008] One objective of this invention is to provide a geomembrane tension adjustment and anchorage deformation monitoring and control device, which can monitor geomembrane anchorage deformation data in real time and automatically adjust the geomembrane tension based on the geomembrane anchorage deformation data to control deformation, thus solving the geomembrane deformation problem existing in the prior art geomembrane anchorage method.

[0009] Another objective of this invention is to propose a method for monitoring geomembrane tension adjustment and anchorage deformation. By precisely constraining the displacement of the geomembrane anchorage end and evenly dispersing the anchorage stress, this method effectively suppresses the wrinkling, tearing, and tensile deformation of the geomembrane caused by temperature changes, stress concentration, or external loads during the anchorage process, thereby improving the stability and durability of the geomembrane anchorage structure.

[0010] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, the present invention provides a geomembrane tension adjustment and anchorage deformation monitoring and control device, comprising an anchoring mechanism, a data processing mechanism, and a hoisting mechanism, wherein: The anchoring mechanism includes a first protective shell and a base plate. The base plate is used to fix the entire monitoring and control device to the surrounding structure (such as the ground, concrete base, anchoring trench, or adjacent geosynthetic materials), and the protective shell protects the monitoring and control device. The data processing mechanism and the winch mechanism are located inside the first protective shell and are connected to the base plate. The winch mechanism includes a clamping structure and a bidirectional winch structure. A material roller is rotatably mounted on the clamping structure to clamp the free end of the geomembrane. One end of the material roller is connected to the bidirectional winch structure, which rotates forward or backward to adjust the tension of the geomembrane. The winch and tension gauge of the bidirectional winch structure are connected to the data processing mechanism. The data processing mechanism receives tension gauge data in real time. When the readings of the two tension gauges are different, it indicates that the geomembrane has become loose or tight. The data processing mechanism then feeds the signal back to the winch mechanism, driving the winch to adjust the tension of the geomembrane.

[0011] As one possible embodiment of the first aspect of the present invention, the bidirectional winch structure includes a forward winch, a reverse winch, and a drum. The forward winch and the reverse winch are respectively wound around the drum by traction ropes. A tension gauge is provided on the traction rope to monitor the tension of the geomembrane in real time and transmit the monitored data to a data processing mechanism for processing. The drum is mounted on a material roller.

[0012] As a possible embodiment of the first aspect of the present invention, it further includes a displacement monitoring structure located at both ends of the material roller in a staggered manner. The displacement monitoring structure is connected to the data processing mechanism and is used to monitor the degree of torsion of the material roller.

[0013] As one possible implementation of the first aspect of the present invention, the displacement monitoring structure includes a fastening ring, a reflector, and a laser rangefinder. The fastening rings are respectively installed at both ends of the material roller, and a reflector is provided on each fastening ring. The two reflectors are located on different sides and are staggered. A laser rangefinder is provided directly below each reflector. The laser rangefinder is connected to a data processing mechanism. When the data processing mechanism detects that the sum of the data from the laser rangefinders on both sides does not meet the set value, that is, the entire material roller on the surface has not been fully twisted, it can be indirectly determined that the overall tension of the geomembrane is uneven. At this time, it is necessary to send personnel to investigate.

[0014] As one possible implementation of the first aspect of the present invention, the data processing mechanism includes a power supply, a data processing module, and an early warning module. The power supply is used to power the data processing module, the early warning module, and the bidirectional winch structure. The data processing module is individually connected to the forward winch, the reverse winch, the force gauge, and the laser rangefinder, and can control the opening and closing of the winch in real time, and collect the measurement data of the force gauge and the laser rangefinder in real time.

[0015] As one possible embodiment of the first aspect of the present invention, the bottom plate of the anchoring mechanism is provided with multiple bolts at equal intervals along its edge, which are anchored to the ground. A rubber gasket is provided between the bottom plate and the ground to improve the installation stability of the device.

[0016] As one possible embodiment of the first aspect of the present invention, the clamping structure includes a bracket and rollers. The bracket includes a bracket one and a bracket two, which are parallel to each other. Two rollers are rotatably mounted on the bracket one, and a geomembrane is clamped between the two rollers. A material roller is rotatably mounted on the bracket two.

[0017] As one possible embodiment of the first aspect of the present invention, the material roller includes an upper material roller and a lower material roller, and the free end of the geomembrane is pressed between the upper material roller and the lower material roller, thereby achieving the anchoring of the geomembrane.

[0018] A second aspect of the present invention provides a method for geomembrane tension adjustment and anchorage deformation monitoring, which uses the above-mentioned device to monitor the degree of geomembrane tension and anchorage deformation, specifically including: Once the entire device is mounted, anchor it to the ground. Then, the free end of the geomembrane is passed through the clamping structure and clamped on the material roller. The tension of the traction rope of the bidirectional winch structure is adjusted to keep the readings of the two tension gauges at the same set value. Powering the data processing mechanism supplies power to the motor of the bidirectional winch structure. The motor is activated based on the change in the tension count value, keeping the readings of the two tension gauges at the set values ​​to adjust the tension of the geomembrane. The number of times the motor of the bidirectional winch structure operates is set in the data processing mechanism. When the set number of times is exceeded, an alarm is triggered, prompting manual inspection to check for deformation of the geomembrane anchorage.

[0019] As a possible implementation of the second aspect of the present invention, after each adjustment of the tension of the geomembrane, the angle of the motor rotation is monitored by a displacement monitoring structure to monitor whether the geomembrane is stretched or relaxed in place. When the difference between the sum of the angles of the motor rotation detected by the displacement monitoring structures on both sides and the initial value is within the set range, it indicates that the motor rotation is in place.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) A geomembrane tension adjustment and anchorage deformation monitoring and control device of the present invention is provided by setting a winch mechanism at one end of the material roller and setting traction ropes on both sides of one end of the material roller. A tension gauge is set on the traction rope. When the reading of the tension gauge on the two traction ropes changes, it is determined that the geomembrane has deformed. The winch can be turned on to work and adjust the tension of the geomembrane.

[0021] (2) A geomembrane tension adjustment and anchorage deformation monitoring and control device of the present invention has a displacement monitoring structure set at both ends of the material roller. The displacement monitoring structure adopts a laser rangefinder and a reflector. The reflector is installed at the end of the material roller. The device measures the change in the sum of the displacements of the laser rangefinders on both sides from the reflector before and after the winch rotates, and indirectly monitors the torsion angle of the material roller to determine whether the geomembrane has been completely torsioned.

[0022] (3) The present invention provides a method for monitoring geomembrane tension adjustment and anchoring deformation. By analyzing the numerical changes of the forward and reverse tension gauges in the bidirectional winch structure, the power is turned on to supply power to the corresponding winch to contract or relax the geomembrane roll, thereby adjusting the tension of the geomembrane. At the same time, an alarm will be issued if the number of times the power is supplied to the winch exceeds a threshold. Therefore, deformation of the geomembrane during anchoring is avoided, and key areas with severe geomembrane deformation can be detected in time, reducing the excessive stretching deformation or even damage of the geomembrane that is prone to occur in traditional anchoring methods. More optimized, displacement monitoring structures are set at opposite ends of the material roller. By analyzing the sum of the displacements collected by the laser rangefinders on both sides of the displacement monitoring structure, the motor is monitored to ensure that the tension of the geomembrane is adjusted and the motor is in the correct position, thus avoiding overall deformation of the geomembrane during the adjustment process.

[0026] like Figure 1 and 2 As shown, this embodiment of a geomembrane tension adjustment and anchorage deformation monitoring and control device includes an anchoring mechanism 1, a data processing mechanism 2, and a hoisting mechanism 3. The anchoring mechanism 1 includes a first protective shell 101 and a base plate 102. The first protective shell 101 is fixedly installed on the base plate 102, and the base plate 102 is anchored to the surrounding structure. Specifically, as shown... Figure 2 As shown, the bottom plate 102 of the anchoring mechanism 1 is provided with multiple bolts 104 at equal intervals along its edge. The bolts 104 are used to anchor the bottom plate 102 to the ground or the dam toe. A gasket 105 is also provided at the connection between the bolt 104 and the bottom plate 102. A rubber gasket 103 is provided between the bottom plate 102 and the contact surface of the surrounding structure to prevent the bottom plate 102 from directly contacting the ground and reduce the wear of the bottom plate 102.

[0027] The data processing mechanism 2 and the hoisting mechanism 3 are located inside the first protective housing 101 and are connected to the base plate 102. The first protective housing 101 and the base plate 102 form a mounting cavity, inside which the data processing mechanism 2 and the hoisting mechanism 3 are installed. Figure 3As shown, the data processing mechanism 2 includes a second protective shell 201, a power supply 202, a data processing module 203, and an early warning module 204. Because it houses the power supply equipment, and the geomembrane installation environment is complex, a waterproof second protective shell 201 is installed to protect the power supply 202, data processing module 203, and early warning module 204 inside, ensuring that all components can operate normally underwater. The power supply 202 provides power to the data processing module 203, the early warning module 204, and the displacement monitoring structure 301 and the bidirectional winch structure 303 in the winch mechanism 3. The data processing module 203 processes and analyzes the changes in the readings of the tension gauge in the winch mechanism 3, and drives the motor of the winch mechanism 3 according to the different changes in the tension gauge readings, adjusting the tension of the geomembrane when anchoring deformation occurs.

[0028] The winch mechanism 3 includes a clamping structure 302 and a bidirectional winch structure 303. A material roller 3023 is rotatably mounted on the clamping structure 302, and the material roller 3023 is used to clamp the free end of the geomembrane 4. One end of the material roller 3023 is connected to the bidirectional winch structure 303. The bidirectional winch structure 303 rotates forward or backward to drive the material roller 3023 to rotate, thereby adjusting the tension of the geomembrane 4. The motor and tension gauge of the bidirectional winch structure 303 are respectively connected to the data processing mechanism 2.

[0029] Specifically, such as Figure 4As shown, the bidirectional winch structure 303 includes a forward winch 3032, a reverse winch 3033, and a drum 3037. The forward winch 3032 and the reverse winch 3033 are respectively mounted on the base plate 102 via bases. The drum 3037 is threaded to the end of the material roller 3023. The forward winch 3032 and the reverse winch 3033 are respectively wound around the drum 3037 via traction ropes 3034. Each of the two traction ropes 3034 is equipped with a tension gauge. A forward tension gauge 3035 is installed in the middle of the traction rope 3034 connected to the forward winch 3032, and a reverse tension gauge 3036 is installed in the middle of the traction rope 3034 connected to the reverse winch 3033. The forward tension gauge 3035 and the reverse tension gauge 3036 are used to measure the tension on the traction ropes 3034. During installation, adjust the tension of the geomembrane, and then adjust the traction force of the two traction ropes 3034 to the set value, that is, the readings of the forward tension gauge 3035 and the reverse tension gauge 3036 are consistent. The forward tension gauge 3035 mainly measures the tension value of the forward winch 3032 during the tightening or loosening of the traction rope 3034, while the reverse tension gauge 3036 mainly measures the tension value of the reverse winch 3033 during the tightening or loosening of the traction rope 3034. The forward tension gauge 3035, the reverse tension gauge 3036, and the data processing module 203 are connected to transmit the detected tension data to the data processing module 203 for analysis. When the geomembrane 4 is stretched, the tension value on the reverse tension gauge 3036 increases while the tension value on the forward tension gauge 3035 decreases. At this time, the data processing module 203 controls the power supply 202 to supply power to the forward winch 3032 and the reverse winch 3033. The forward winch 3032 tightens the traction rope 3034 and drives the winch. The drum 3037, the material roller 3023, and the geomembrane 4 rotate counterclockwise. At the same time, the reverse winch 3033 will simultaneously loosen the traction rope 3034, allowing the material roller 3023 and the geomembrane 4 to rotate smoothly, thereby achieving the loosening of the geomembrane 4. When the data processing module 203 detects that the tension values ​​displayed by the forward tension gauge 3035 and the reverse tension gauge 3036 are equal, it stops supplying power to the forward winch 3032 and the reverse winch 3033. At this moment, the geomembrane 4 returns to its initial unstretched state.

[0030] When the geomembrane 4 becomes loose, the tension value on the reverse tension gauge 3036 decreases while the tension value on the forward tension gauge 3035 increases. At this time, the data processing module 203 controls the power supply 202 to supply power to the forward winch 3032 and the reverse winch 3033. The reverse winch 3032 tightens the traction rope 3034, while the forward winch 3033 simultaneously loosens the traction rope 3034, causing the drum 3037, the material roller 3023, and the geomembrane 4 to rotate clockwise until the tension values ​​on the forward tension gauge 3035 and the reverse tension gauge 3036 are equal. The data processing module then controls the power supply 202 to stop supplying power to the forward winch 3032 and the reverse winch 3033. At this time, the geomembrane 4 returns to its initial unloose state.

[0031] More optimized, combined Figure 4 and Figure 5 In this embodiment, displacement monitoring structures 301 are offset at both ends of the material roller 3023. These structures are connected to the data processing mechanism 2 and are used to monitor the degree of torsion of the material roller 3023. Each displacement monitoring structure 301 includes a fastening ring 3011, a reflector 3012, and a laser rangefinder 3013. The fastening rings 3011 are respectively installed at both ends of the material roller 3023, and are threadedly connected to the roller 3023. Each fastening ring 3011 has a reflector 3012, with the two reflectors located on different sides and offset. A laser rangefinder 3013 is positioned directly below each reflector 3012, and the laser rangefinder 3013 is connected to the data processing module 203 of the data processing mechanism 2. After adjusting the tension of the geomembrane 4, the sum of the readings of the two laser rangefinders 3013 can be checked to see if it meets the set value. If it does, it indicates that the material roller 3023 has rotated as a whole. If it does not meet the set value, it indicates that the adjustment has not been completed. The warning module 204 can be used to issue a warning and prompt the operator to check.

[0032] Combination Figure 5 The clamping structure 302 includes a bracket 3022 and rollers 3021. The bracket 3022 includes a first bracket and a second bracket, which are parallel to each other. Two rollers 3021 are rotatably mounted on the first bracket via bearing components, and the geomembrane 4 is clamped between the two rollers 3021. A material roller 3023 is rotatably mounted on the second bracket. Figure 7As shown, the material roller 3023 includes an upper material roller 3023-1 and a lower material roller 3023-2. The free end of the geomembrane 4 is pressed between the upper material roller 3023-1 and the lower material roller 3023-2. The contact surfaces of the upper material roller 3023-1 and the lower material roller 3023-2 are processed into a wavy structure, which improves the clamping firmness of the geomembrane 4 compared to the existing flat surface. At the same time, both ends of the upper material roller 3023-1 and the lower material roller 3023-2 are processed with threads to facilitate the installation with the fastening ring 3011 and the roller 3021.

[0033] The device in this embodiment effectively suppresses wrinkling, tearing, and tensile deformation of the geomembrane during anchoring by precisely constraining the displacement of the geomembrane anchoring end and evenly dispersing the anchoring stress, thereby improving the stability and durability of the geomembrane anchoring structure.

[0034] Furthermore, this embodiment also provides a method for monitoring geomembrane tension adjustment and anchorage deformation using the aforementioned device, specifically including: Once the entire device is mounted, anchor it to the ground. Then, the free end of the geomembrane 4 is passed through the clamping structure 302 and clamped on the material roller 3023. The tension of the traction rope of the bidirectional winch structure 303 is adjusted to keep the readings of the two tension gauges at the same set value. Powering the data processing mechanism 2 supplies power to the motor of the bidirectional winch structure 303. The motor of the bidirectional winch structure 303 is started to work according to the change of the tension count value, so that the readings of the two tension gauges are kept at the set value, thereby adjusting the tension of the geomembrane 4. The number of times the motor of the bidirectional winch structure 303 works is set in the data processing mechanism 2. When the set number of times is exceeded, an alarm is issued to prompt manual inspection to check whether there is deformation in the anchoring of the geomembrane 4.

[0035] In a more optimized configuration, after each adjustment of the geomembrane 4's tension, the laser rangefinder 3013 and reflector 3012 of the displacement monitoring structure 301 monitor the motor's rotation angle to determine whether the geomembrane 4 has been stretched or relaxed sufficiently. If the difference between the sum of the angles detected by the two displacement monitoring structures 301 and the initial value is within the set range, it indicates that the motor has rotated sufficiently. Conversely, if the difference is not within the set range, the early warning module 204 will issue a warning, prompting the operator to address the issue.

[0036] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.

Start the motor of the bidirectional winch structure (303) to work according to the change of the tension count value, so that the readings of the two tension gauges remain at the set value, so as to adjust the tension of the geomembrane (4). In addition, the number of times the motor of the bidirectional winch structure (303) works is set in the data processing mechanism (2). When the set number of times is exceeded, an alarm is issued to prompt the personnel to check whether there is deformation in the anchoring of the geomembrane (4).

10. The method for monitoring geomembrane tension adjustment and anchorage deformation according to claim 9, characterized in that: After each adjustment of the tension of the geomembrane (4), the angle of the motor rotation is monitored by the displacement monitoring structure (301) to monitor whether the geomembrane (4) is stretched or relaxed in place. When the difference between the sum of the angles of the motor rotation detected by the displacement monitoring structures (301) on both sides and the initial value is within the set range, it indicates that the motor rotation is in place.
