Description

Technical Field

[0001] This invention relates to the field of geomembrane laying, and more specifically to a counterweight device for laying vertical barrier geomembranes. Background Technology

[0002] In current contaminated site remediation projects, existing vertical barrier structures mainly consist of a geomembrane at the center of the wall and a mortar protective layer surrounding the geomembrane. Specifically, during construction, trenches are first constructed using trenching equipment; then, a geomembrane laying frame or geomembrane laying machine is used to lay the geomembrane, inserting it from top to bottom to the center of the trench until the bottom of the geomembrane is inserted to the bottom of the trench; finally, the mortar protective layer is poured in. However, in actual construction, problems often arise such as the bottom of the geomembrane not being reliably inserted to the center of the wall, as well as geomembrane twisting and floating. Summary of the Invention

[0003] The purpose of this invention is to provide a counterweight device for vertically blocking geomembranes that can effectively solve the problems of unreliable insertion of the bottom of the geomembrane into the center of the wall, as well as the problems of geomembrane twisting and floating in the prior art.

[0004] The technical solution of this invention is: A counterweight device for deploying a vertical barrier geomembrane, the counterweight device comprising two counterweight components distributed on opposite sides of the geomembrane, the counterweight components comprising: Adhesive blocks are fixed to the lower part of the geomembrane; A counterweight block is suspended below the adhesive block by a connecting rope. The bottom end of the counterweight block is at the same height as the bottom end of the geomembrane, or the bottom end of the counterweight block is higher than the bottom end of the geomembrane. With this design, during the laying process using a membrane-laying frame or a membrane-laying machine, and after being laid to the bottom of the trench, the geomembrane within the trench remains in a vertically tensile state under the weight of the counterweight block, effectively solving the problems of geomembrane twisting and floating. Simultaneously, two counterweight components are distributed on opposite sides of the geomembrane. During the laying process, the counterweight block can cooperate with the inner wall of the trench to provide preliminary auxiliary positioning for the bottom of the geomembrane, ensuring that the bottom of the geomembrane can be inserted into the center of the wall after being laid to the bottom of the trench.

[0005] On the other hand, the bottom of the counterweight is at the same height as the bottom of the geomembrane, or the bottom of the counterweight is higher than the bottom of the geomembrane. In this way, after the geomembrane is laid to the bottom of the trench, it can be ensured that the bottom of the geomembrane is close to the bottom of the trench.

[0006] Preferably, the counterweight blocks rest against the side of the geomembrane, and the counterweight blocks of the two counterweight components of the same counterweight device are at the same height. After the counterweight blocks of the two counterweight components of the same counterweight device are pressed together under their own weight, they will clamp the bottom of the geomembrane. In this way, it is beneficial to play a guiding and auxiliary positioning role for the bottom of the geomembrane during the laying process.

[0007] Preferably, the two counterweight components of the same counterweight device are symmetrically distributed on opposite sides of the geomembrane.

[0008] Preferably, it also includes a bottom-reaching centering support mechanism, which corresponds one-to-one with the counterweight components. The bottom-reaching centering support mechanism includes: The support is a diagonal rod, the lower end of which is hinged to the corresponding counterweight, and the upper end of which extends diagonally upwards and outwards from the counterweight. Support rod, which is fixed to the upper end of the support diagonal rod; Vertical guide holes are set on the corresponding counterweights and penetrate through the counterweights; The top support rod opening is set on the outer side of the corresponding counterweight block and connected to the vertical guide hole; The top support rod is set on the upper part of the support diagonal rod, and the end of the top support rod passes through the top support rod opening and extends into the vertical guide hole; A floating locking rod is slidably installed in a vertical guide hole. The bottom end of the floating locking rod is located below the bottom end of the geomembrane. The top of the floating locking rod is provided with a locking slope. The top support rod faces the locking slope, and there is a gap between the end of the top support rod and the locking slope.

[0009] During the process of laying the geomembrane from top to bottom into the trench, the support rod abuts against the inner wall of the trench under its own weight, and the support rod can rotate around the hinge axis at the lower end of the support rod towards the geomembrane; when the bottom of the geomembrane is laid to the bottom of the trench, the floating locking rod is supported at the bottom of the trench and moves upward along the vertical guide hole so that the locking inclined surface abuts against the end of the top support rod.

[0010] While counterweights placed on both sides of the geomembrane can provide initial, auxiliary positioning for the bottom of the geomembrane, a sufficient gap (typically 10-20 cm) must be maintained between the counterweights and the trench wall to ensure smooth installation. This prevents accurate centering of the geomembrane bottom within the wall, and the counterweights may tilt after the geomembrane reaches the trench bottom, further affecting the geomembrane's placement. To address this issue, this solution incorporates a bottom-contact centering support mechanism. This mechanism, after the geomembrane reaches the trench bottom, centers the bottom of the geomembrane within the wall without hindering its smooth installation, preventing the counterweights from tilting and affecting the geomembrane's placement. Specifically… During the process of laying the geomembrane from top to bottom into the trench, the supporting rods abut against the inner wall of the trench under their own weight, and the supporting rods can rotate around the hinge axis at the lower end of the supporting rods towards the geomembrane. Thus, during the laying of the geomembrane, when the supporting rods encounter obstacles on the inner wall of the trench (such as protrusions on the inner wall of the trench), the supporting rods can rotate around the hinge axis at the lower end of the supporting rods towards the geomembrane, thereby bypassing the obstacles and ensuring the smooth laying of the geomembrane.

[0011] When the bottom of the geomembrane is laid to the bottom of the trench, the bottom end of the floating locking rod is supported at the bottom of the trench and moves upward along the vertical guide hole so that the locking ramp abuts against the end of the top support rod. Specifically, when the geomembrane is close to the bottom of the trench, the bottom end of the floating locking rod is first supported at the bottom of the trench. Then the counterweight continues to move down until it is supported at the bottom of the trench. During this process, the floating locking rod moves upward along the vertical guide hole so that the locking ramp abuts against the end of the top support rod. The top support rod drives the support rod to rotate around the hinge axis at the lower end of the support ramp towards the outside of the counterweight, so that the support rod abuts against the inner wall of the trench. This achieves the centering and positioning of the bottom of the geomembrane at the center of the wall. At the same time, the bottom-contact centering support mechanism supports the counterweight to prevent the counterweight from tilting and affecting the placement of the bottom of the geomembrane.

[0012] Preferably, the support diagonal rod and the corresponding counterweight are connected by a connecting line. In this way, the initial position of the support diagonal rod can be defined by the connecting line.

[0013] Preferably, the bottom-contact centering support mechanisms on the two counterweight components of the same counterweight device are distributed on opposite sides of the geomembrane.

[0014] Preferably, the counterweight has a bottom slope, and the bottom slopes of the counterweights in the two counterweight components of the same counterweight device form a V-shaped structure. This facilitates the counterweights in inserting the geomembrane into the trench.

[0015] As a preferred option, the counterweight is a precast reinforced concrete block.

[0016] Preferably, the top of the counterweight is provided with an embedded part, and the lower end of the connecting rope is connected to the embedded part. This facilitates the connection between the connecting rope and the counterweight.

[0017] The beneficial effects of this invention are: during the laying process and after the geomembrane is laid to the bottom of the trench, the geomembrane inside the trench remains in a vertically tensile state under the weight of the counterweights, thus effectively solving the problems of geomembrane twisting and floating. Simultaneously, the two counterweight components are distributed on opposite sides of the geomembrane. During the laying process, the counterweights can cooperate with the inner wall of the trench to provide a guiding and auxiliary positioning function for the bottom of the geomembrane, ensuring that the bottom of the geomembrane can be inserted into the center of the wall after it is laid to the bottom of the trench.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Specific Implementation Example 1, such as Figure 1 , Figure 2 As shown, a counterweight device for deploying a vertical barrier geomembrane includes two counterweight components 1. The two counterweight components are distributed on opposite sides of the geomembrane 2. In this embodiment, the two counterweight components of the same counterweight device are symmetrically distributed on opposite sides of the geomembrane.

[0025] The counterweight assembly 1 includes an adhesive block 1.1 and a counterweight block 1.2. The adhesive block is fixed to the lower part of the geomembrane by means of adhesive bonding or by heat fusion welding. In this embodiment, the adhesive block is fixed to the lower part of the geomembrane by heat fusion welding, and the adhesive block and the geomembrane are made of the same material. The adhesive block is located near the bottom of the geomembrane.

[0026] The counterweight is suspended below the adhesive block by connecting rope 1.3. The bottom end of the counterweight is at the same height as the bottom end of the geomembrane, or the bottom end of the counterweight is higher than the bottom end of the geomembrane. In this embodiment, the bottom end of the counterweight is at the same height as the bottom end of the geomembrane. The counterweight in the same counterweight assembly is one unit.

[0027] In actual construction, such as Figure 3 As shown, the bottom of the geomembrane is equipped with several counterweight devices, which are distributed sequentially along the bottom edge of the geomembrane, with a spacing of 1-3 meters between two adjacent counterweight devices.

[0028] In this embodiment, during the laying process using a membrane-laying frame or a membrane-laying machine, and after being laid to the bottom of the trench, the geomembrane within the trench remains in a vertically tensile state under the weight of the counterweights, effectively solving the problems of geomembrane twisting and floating. Simultaneously, two counterweight components are distributed on opposite sides of the geomembrane. During laying, the counterweights work in conjunction with the inner wall of the trench to provide preliminary auxiliary positioning for the bottom of the geomembrane, ensuring that the bottom of the geomembrane can be inserted into the center of the wall after being laid to the bottom of the trench. Furthermore, the bottom end of the counterweights is at the same height as the bottom end of the geomembrane, thus ensuring that the bottom of the geomembrane is firmly against the bottom of the trench after being laid.

[0029] Specifically, the counterweight is a precast reinforced concrete block. An embedded part 1.4 is located at the top of the counterweight, and the lower end of the connecting rope is connected to this embedded part. This facilitates the connection between the connecting rope and the counterweight.

[0030] In this embodiment, the connecting rope is made of the same material as the geomembrane, and its length ensures that the bottom of the counterweight is flush with the bottom of the geomembrane. It should be noted, however, that the connecting rope can also be made of other materials, such as plastic rope, nylon rope, or steel wire rope.

[0031] The counterweight blocks rest against the side of the geomembrane. Specifically, the side of the counterweight block facing the geomembrane is a flat surface, and this flat surface rests against the side of the geomembrane under the weight of the counterweight block. The counterweight blocks of the two counterweight components of the same counterweight device are at the same height. After the counterweight blocks of the two counterweight components of the same counterweight device are pressed together under their own weight, they will clamp the bottom of the geomembrane. In this way, it is beneficial to guide and assist in positioning the bottom of the geomembrane during the laying process.

[0032] The counterweight has a 1.5-degree slope at its bottom. The bottom slopes of the counterweights in the two counterweight components of the same counterweight device form a V-shaped structure. This facilitates the insertion of the geomembrane into the trench by the counterweight.

[0033] In this second specific embodiment, the remaining structure is the same as in the first specific embodiment, except that... like Figure 4 , Figure 5 As shown, a counterweight device for deploying vertical barrier geomembranes further includes a bottom-aligning support mechanism 3, which corresponds one-to-one with the counterweight components. In this embodiment, the bottom-aligning support mechanisms on the two counterweight components of the same counterweight device are said to be distributed on opposite sides of the geomembrane.

[0034] The bottom-reaching centering support mechanism 3 includes a support diagonal rod 3.1, a support top rod 3.2, a vertical guide hole 3.3, a top support rod through-hole 3.5, a top support rod 3.6, and a floating locking rod 3.4. The lower end of the support diagonal rod 3.1 is hinged to the counterweight block of the corresponding counterweight assembly. The upper end of the support diagonal rod extends obliquely upwards and outwards from the counterweight block. In this embodiment, the support diagonal rod and the corresponding counterweight block are connected by a connecting line 3.8.

[0035] The support rod 3.2 is fixed to the upper end of the support diagonal rod. In this embodiment, the support rod is parallel to the geomembrane, the support rod is horizontally distributed, and the support rod is parallel to the hinge axis at the lower end of the support diagonal rod.

[0036] A vertical guide hole 3.3 is provided on the corresponding counterweight and passes through the counterweight. A strut through-hole 3.5 is provided on the outer side of the corresponding counterweight and connects to the vertical guide hole.

[0037] The top support rod 3.6 is installed on the upper part of the support diagonal rod. The end of the top support rod passes through the top support rod opening and extends into the vertical guide hole.

[0038] The floating locking rod 3.4 is slidably mounted inside the vertical guide hole. In this embodiment, the upper end of the floating locking rod is connected to the top of the counterweight block via a suspension rope, so that the floating locking rod is suspended inside the vertical guide hole. The bottom end of the floating locking rod is located below the vertical guide hole and below the bottom end of the geomembrane. The top of the floating locking rod is provided with a locking ramp 3.7, the upper part of which slopes towards the geomembrane. The top support rod faces the locking ramp, and there is a gap between the end of the top support rod and the locking ramp.

[0039] During the process of laying the geomembrane from top to bottom into the trench 4, the support rod abuts against the inner wall of the trench under its own weight, and the support rod can rotate around the hinge axis at the lower end of the support rod towards the geomembrane.

[0040] When the geomembrane is laid to the bottom of the trench, the floating locking rod is supported at the bottom of the trench and moves upward along the vertical guide hole so that the locking ramp abuts against the end of the top support rod.

[0041] While counterweights placed on both sides of the geomembrane can provide initial, auxiliary positioning for the bottom of the geomembrane, a sufficient gap (typically 10-20 cm) must be maintained between the counterweights and the trench wall to ensure smooth installation. This prevents accurate centering of the geomembrane bottom within the wall, and the counterweights may tilt after the geomembrane reaches the trench bottom, further affecting the geomembrane's placement. To address this issue, this solution incorporates a bottom-contact centering support mechanism. This mechanism, after the geomembrane reaches the trench bottom, centers the bottom of the geomembrane within the wall without hindering its smooth installation, preventing the counterweights from tilting and affecting the geomembrane's placement. Specifically… During the process of laying the geomembrane from top to bottom into the trench, the supporting rods abut against the inner wall of the trench under their own weight, and the supporting rods can rotate around the hinge axis at the lower end of the supporting rods towards the geomembrane. Thus, during the laying of the geomembrane, when the supporting rods encounter obstacles on the inner wall of the trench (such as protrusions on the inner wall of the trench), the supporting rods can rotate around the hinge axis at the lower end of the supporting rods towards the geomembrane, thereby bypassing the obstacles and ensuring the smooth laying of the geomembrane.

[0042] When the bottom of the geomembrane is laid to the bottom of the trench, the bottom end of the floating locking rod is supported at the bottom of the trench and moves upward along the vertical guide hole so that the locking ramp abuts against the end of the top support rod. Specifically, when the geomembrane is close to the bottom of the trench, the bottom end of the floating locking rod is first supported at the bottom of the trench. Then the counterweight continues to move down until it is supported at the bottom of the trench. During this process, the floating locking rod moves upward along the vertical guide hole so that the locking ramp abuts against the end of the top support rod. The top support rod drives the support rod to rotate around the hinge axis at the lower end of the support ramp towards the outside of the counterweight, so that the support rod abuts against the inner wall of the trench. This achieves the centering and positioning of the bottom of the geomembrane at the center of the wall. At the same time, the bottom-contact centering support mechanism supports the counterweight to prevent the counterweight from tilting and affecting the placement of the bottom of the geomembrane.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, alterations, and equivalent transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
