Description

Technical Field

[0001] This invention relates to the field of vertical seepage prevention technology, and more specifically to a GCL vertical laying fixing component and its vertical laying method. Background Technology

[0002] Sodium-based bentonite waterproofing blankets (GCL) composite vertical barrier technology introduces GCL into the field of vertical seepage control, combining it with low-permeability walls to form a composite seepage control structure. The low-permeability wall can be a conventional seepage control wall or a reactive pollution control wall designed according to specific pollutants. The low-permeability wall initially blocks pollutant migration, while the GCL significantly improves the overall seepage control performance. As a composite seepage control structure, GCL composite vertical barrier technology can cope with complex polluted environments, solving problems such as easy leakage at joints and poor wall seepage control performance inherent in conventional seepage control walls. It has been applied in multiple existing waste management projects and is also suitable for tailings treatment, tunnels and subways, water conservancy landscapes, and environmental remediation.

[0003] Currently, when vertically fixing GCLs, the GCLs are first laid vertically in the trench. The fixing method for the top of the GCL is as follows: Figure 1 As shown, an anchoring trench is dug on one side of the trench, the top of the GCL is placed inside the anchoring trench, and then concrete or clay is backfilled and compacted inside the anchoring trench. However, in actual construction, this type of GCL fixing method is complex, requiring the excavation and backfilling of the anchoring trench; it also has high site requirements, requiring sufficient working surface outside the trench for excavation; furthermore, if GCLs are laid on both sides of the excavated trench, this fixing method will also affect the construction of other processes. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a vertical laying and fixing component for GCL and its vertical laying method, which can overcome the above-mentioned defects in the existing technology and has the characteristics of less site restriction, no need to open additional anchor trenches, simple operation and low construction cost.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0014] Pour the wall material into the trench, and remove the supporting components after pouring is complete.

[0015] In this invention, preferably, the GCL vertical laying and fixing assembly further includes an adjustment assembly, which provides support to the support member and adjusts the spacing between the support member and the trench by means of the tensile force received by the GCL waterproof blanket. The adjustment assembly includes...

[0016] Support base,

[0017] The hydraulic assembly includes a first pressure cylinder and a second pressure cylinder, which are interconnected and contain a flowing fluid between them. The output directions of the two pressure cylinders are opposite.

[0018] The counterweight is fixedly connected to the output end of the second pressure cylinder.

[0019] A lifting float is fixedly connected to the output end of the first pressure cylinder. The lifting float is used to support the support member. When the support member squeezes the lifting float, the circulating liquid can flow from the first pressure cylinder to the second pressure cylinder to make the lifting float descend.

[0020] In this invention, preferably, the output end of the second pressure cylinder is provided with an elastic adjustment member. When the lifting float descends, the elastic force on the elastic adjustment member can change to increase the load on the output end of the second pressure cylinder.

[0021] In this invention, preferably, the lifting float is provided with a support assembly, which includes a plurality of fixing members and a plurality of supporting members. The fixing members and the supporting members are arranged opposite each other on both sides of the groove. The fixing members and the lifting float are rotatably connected so that the fixing members can be vertically flipped. One end of the supporting member is detachably connected to the fixing member so that the supporting member can be flipped with the fixing member. The supporting member is used to support the other end of the supporting member.

[0022] In this invention, preferably, a sleeve portion is formed on one end of the support member, the fixing member includes an elastic sleeve, an abutment ring, and a reset member, one end of the elastic sleeve is formed with an elastic claw, the elastic claw is elastic so that its outer diameter is variable, the abutment ring is slidably connected to the elastic sleeve, the abutment ring is abutted against the end face of the sleeve portion so that the abutment ring slides away from the elastic claw, and when the abutment ring slides away from the elastic claw, the elastic claw resets and abuts against the sleeve portion, the reset member is used to reset the abutment ring.

[0023] In this invention, preferably, a limiting portion is formed on the support member, the limiting portion being used to abut against the end of the support member to restrict the movement of the support member.

[0024] In this invention, preferably, the lifting float is provided with a plurality of float sections, and the spacing between each float section is adjustable to adjust the spacing between the fixing members.

[0025] In this invention, preferably, a vertical GCL laying and fixing assembly is provided. The GCL vertical laying and fixing assembly further includes an adjusting assembly. The adjusting assembly provides support for the support member and adjusts the spacing between the support member and the trench by the tensile force received by the GCL waterproof blanket. The adjusting assembly includes...

[0026] Support base,

[0027] The hydraulic assembly includes a first pressure cylinder and a second pressure cylinder, which are interconnected and contain a flowing fluid between them. The output directions of the two pressure cylinders are opposite.

[0028] The counterweight is fixedly connected to the output end of the second pressure cylinder.

[0029] A lifting float is fixedly connected to the output end of the first pressure cylinder. The lifting float is used to support the support member. When the support member squeezes the lifting float, the circulating liquid can flow from the first pressure cylinder to the second pressure cylinder to make the lifting float descend.

[0030] The vertical laying and fixing method of GCL includes:

[0031] Lower the GCL waterproof blanket from the roll onto one side of the trench to the preset depth.

[0032] Several holes were formed by puncturing the upper part of the GCL waterproof blanket.

[0033] Support members are inserted into each of the holes to provide support for the GCL waterproof blanket. The two ends of the support rods are mounted on the lifting floating plate.

[0034] Wall material is poured into the trench. When the GCL waterproof blanket is squeezed, the lifting float can descend to lower the GCL waterproof blanket. As the descent distance of the GCL waterproof blanket increases, the load on the output end of the second output cylinder increases.

[0035] The beneficial effects of this invention are:

[0036] 1. Compared with the existing anchoring trench, the present invention uses external support members to support the GCL waterproof blanket, eliminating the need for additional space for fixing the GCL waterproof blanket. It is suitable for narrow sections on both sides of the trench, is less affected by the construction environment, has a wide range of applications, and is simple to construct, which can significantly save construction time. In addition, the tools involved in this application are reusable, and the material and mechanical costs are negligible. The cost is very low compared to the anchoring trench. At the same time, it has a good fixing effect on the GCL waterproof blanket, which is not prone to falling. The GCL waterproof blanket punctured at the top exceeds the height of the wall and will not affect the seepage prevention performance of the vertical barrier.

[0037] 2. This application includes an adjustment component, which allows for fine-tuning of the support height of the GCL waterproof blanket. When the GCL waterproof blanket is compressed during the pouring process, to prevent excessive stress on the connection between the GCL waterproof blanket and the support, the height of the support can be lowered, thereby reducing the force at the connection between the GCL waterproof blanket and the support. At the same time, the adjustment component itself has a certain counterweight, which ensures that the GCL waterproof blanket remains flat during the pouring process, so that the final composite vertical barrier has good seepage prevention performance.

Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0049] Example 1:

[0050] Please see Figures 2 to 3 This embodiment provides a vertical laying and fixing component for GCL, including a roller 3, a GCL waterproof blanket 1 and a support 4. The support 4 can be set as a rigid support that is not easy to bend, such as a steel pipe, square steel, steel bar, or wooden stick. One end of the GCL waterproof blanket 1 is rolled up on the roller 3, and the support 4 is set on both sides of the trench and provides support by passing through the GCL waterproof blanket 1.

[0051] A method for vertically laying and fixing GCLs, providing the above-mentioned vertical laying and fixing component for GCLs, the method for vertically laying and fixing GCLs includes:

[0052] Lower the GCL waterproof blanket 1 on the roll 3 to the preset depth on one side of the trench;

[0053] Several holes are formed by puncturing the upper end of the GCL waterproof blanket 1, which is flush with the guide wall. The horizontal position of the holes is as even as possible so that the supporting force of the support member 4 can be evenly applied to the GCL waterproof blanket 1. The number of holes is set according to the horizontal length of the GCL waterproof blanket 1. The tools involved in this step are a utility knife or scissors, which can be reused. In addition, the GCL punctured at the top has exceeded the GCL used for wall composite, and will not affect the seepage prevention performance of the composite vertical barrier.

[0054] Support members 4 are inserted into each hole. The two ends of the support members 4 are placed on the guide wall to provide support for the GCL waterproof blanket 1. Multiple support members 4 support the GCL, making it less likely to fall.

[0055] Pour the wall material into the trench, and remove the support component 4 after pouring is completed.

[0056] Compared to the existing anchoring trench 2, this invention uses the support member 4 to provide support for the GCL waterproof blanket 1, eliminating the need for additional space for fixing the GCL waterproof blanket 1. This is suitable for narrow sections on both sides of the trench, is less affected by the construction environment, has a wide range of applications, and is simple to construct, significantly saving construction time. In addition, all tools involved in this application are reusable, and the material and machinery costs are negligible, making the cost much lower than that of the anchoring trench 2. At the same time, it provides good fixation for the GCL waterproof blanket 1, reducing the risk of it falling. Even if the top of the GCL waterproof blanket 1 is punctured beyond the height of the wall, it will not affect the seepage prevention performance of the vertical barrier.

[0057] Example 2:

[0058] Please refer to Figures 4 to 6 This embodiment provides a vertical GCL laying and fixing component. In addition to the structure in Embodiment 1, the GCL vertical laying and fixing component also includes an adjustment component. The adjustment component provides support for the support member 4 and adjusts the distance between the support member 4 and the groove by adjusting the tension on the GCL waterproof blanket 1. The adjustment component is designed considering that the holes on the GCL waterproof blanket 1 are made on-site using tools such as scissors. Therefore, the hole area is the weakest part of the entire GCL waterproof blanket 1. During the pouring of wall material, the poured material will inevitably shrink, so the hole area will be subjected to a large force, which can easily lead to damage to the hole area. In severe cases, it can cause the support for the GCL waterproof blanket 1 to fail, and the waterproof blanket to sag.

[0059] Specifically, the adjustment assembly includes a support base 5, a hydraulic system, a counterweight 621, and a lifting float 611. The support base 5 includes two support sections, which are installed on both sides of the trench. Two sets of the hydraulic system, the counterweight 621, and the lifting float 611 are each provided.

[0060] The hydraulic assembly includes a first pressure cylinder 61 and a second pressure cylinder 62, which are interconnected and contain a circulating fluid. The output directions of the two pressure cylinders 61 and 62 are opposite. A counterweight 621 is fixedly connected to the output end of the second pressure cylinder 62, and a lifting float 611 is fixedly connected to the output end of the first pressure cylinder 61. The lifting float 611 is used to support the support member 4. When the support member 4 presses the lifting float 611, the circulating fluid can flow from the first pressure cylinder 61 to the second pressure cylinder 62, causing the lifting float 611 to descend. This configuration ensures that when the GCL waterproof blanket 1 is stretched, if the pressure of the support member 4 on the lifting float 611 is greater than the load on the output end of the second pressure cylinder 62, the lifting float 611 can descend, reducing the tension on the GCL waterproof blanket 1 and preventing the GCL waterproof blanket 1 from falling due to damage to the perforated parts. This results in a composite vertical barrier with good seepage prevention performance.

[0061] The output end of the second pressure cylinder 62 is provided with an elastic adjusting member 622. When the lifting float 611 descends, the elastic force on the elastic adjusting member 622 can change to increase the load on the output end of the second pressure cylinder 62. In this embodiment, the elastic adjusting member 622 is specifically set as a compression spring. When the lifting float 611 descends, the output end of the second pressure cylinder 62 rises. At this time, the compression spring is compressed, the elastic force increases, and thus the load on the output end of the second pressure cylinder 62 increases.

[0062] A support assembly is provided on the lifting float 611. The support assembly includes several fixing parts 7 and several supporting parts 8, which are arranged opposite each other on both sides of the trench. The fixing parts 7 and the lifting float 611 are rotatably connected, allowing the fixing parts 7 to rotate vertically. One end of the supporting part 4 is detachably connected to the fixing part 7, allowing the supporting part 4 to rotate with the fixing part 7. The supporting parts 8 are used to support the other end of the supporting part 4. The main purpose of the support assembly is to fix the supporting part 4 and prevent its position from shifting during the pouring process, which would affect the laying effect of the GCL waterproof blanket 1.

[0063] A sleeve portion is formed on one end of the support member 4. The fixing member 7 includes an elastic sleeve 71, an abutment ring 72, and a reset member 73. An elastic claw 711 is formed on one end of the elastic sleeve 71. The elastic claw 711 is elastic so that its outer diameter can be variable. The abutment ring 72 is slidably connected to the elastic sleeve 71. The abutment ring 72 is abutted against the end face of the sleeve portion so that the abutment ring 72 slides away from the end of the elastic claw 711. When the abutment ring 72 slides away from the end of the elastic claw 711, the elastic claw 711 resets and abuts against the sleeve portion. The reset member 73 is used to reset the abutment ring 72. In this structure, when the fixing member 7 is in its natural state, the elastic claw 711 is in a contracted state under the action of the reset member 73 and the abutment ring 72, facilitating the sleeve portion on the support member 4 to engage with the outside of the elastic claw 711. Then, the support member 4 presses the abutment ring 72, causing the abutment ring 72 to move away from the elastic claw 711. At this time, the outer diameter of the reset elastic claw 711 gradually increases until it abuts against the sleeve portion. A limiting portion 81 is formed on the support member 8, which abuts against the end of the support member 4 to restrict the movement of the support member 4, enabling quick connection and fixation of the support member 4, while also facilitating disassembly.

[0064] In this embodiment, considering that the specific structure of the support member 4 is limited, when the support member 4 is specifically set as a cylindrical tubular structure such as a steel pipe, it can be used directly. When it is set as a solid structure such as a steel bar or a wooden stick, or a square steel, an external connector can be used to form a sleeve structure at the end of the support member 4, so that the function of this application can be realized.

[0065] The lifting float 611 is equipped with multiple sets of fixing components 7 and supporting components 8. The specific number depends on the construction dimensions of the trench, and can be 3-5 sets. The lifting float 611 includes several float sections, the spacing between which is adjustable to adjust the spacing between the fixing components 7. Specifically, the float sections are connected by a scissor-type telescopic structure, allowing each float section to extend and retract while maintaining the same height to adapt to trenches of different sizes. Furthermore, it can be folded before and after use to reduce the overall size of the device. The number of first support cylinders is consistent with the number of float sections, while the number of second support cylinders can remain unchanged. The difference is that the first support cylinders must be connected to both the first and second support cylinders. The two support sections can also be connected by a telescopic sliding rail.

[0066] This embodiment also provides a method for vertically laying and fixing GCLs, which includes:

[0067] Lower the GCL waterproof blanket 1 on the roll 3 to the preset depth on one side of the trench;

[0068] Several holes were formed by puncturing the upper part of GCL waterproof blanket 1;

[0069] Support members 4 are inserted into each hole to provide support for the GCL waterproof blanket 1, and the two ends of the support rods are mounted on the lifting float 611.

[0070] When wall material is poured into the trench, the lifting float 611 can descend to lower the GCL waterproof blanket 1 when it is squeezed. As the descent distance of the GCL waterproof blanket 1 increases, the load on the output end of the second output cylinder increases.

[0071] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
