AI Technical Summary
When existing geomembranes are anchored to concrete structures, problems such as uneven foundations, debris backing, and geomembrane wrinkles can easily occur, resulting in insufficient compaction of the anchoring structure and inadequate sealing of the edges, which can easily lead to leakage risks.
The first anchoring structure is formed by stainless steel chemical bolts and stainless steel angle steel, which anchors the first geomembrane to the concrete structure. The second anchoring structure is formed by expansion bolts and stainless steel flat steel, which anchors the second geomembrane to the concrete structure. Combined with SR seepage prevention material and elastic sealing agent, the anchoring reliability and sealing performance are enhanced.
This improves the anchoring reliability and sealing performance between the geomembrane and the concrete structure, ensuring that even if the first anchoring structure is at risk of leakage, the second geomembrane can still effectively prevent seepage, thus enhancing the overall seepage prevention effect.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of water conservancy and hydropower engineering, and in particular to a geomembrane and surrounding concrete anchoring reinforcement structure. Background Technology
[0002] With the continuous development of pumped storage power stations, there are more and more sites with complex terrain and geological conditions. Under complex terrain and geological conditions, in order to meet the needs of dam construction and reservoir formation, certain seepage prevention measures are often required. Geomembrane, due to its excellent adaptability to deformation, is often used for seepage prevention at the bottom of reservoirs. The geomembrane and the surrounding concrete structure are anchored together to form a closed seepage prevention system together with the seepage prevention panel on the reservoir bank.
[0003] Existing geomembranes are generally anchored directly to concrete structures. During construction, problems often arise at the anchoring points, such as insufficient smoothness of the foundation grinding, residual debris left in the drill holes, and wrinkles in the geomembrane and cover sheet. These issues result in incomplete compaction of the geomembrane anchoring structure. If the sealing of the anchoring structure is not airtight, leakage is likely to occur at the anchoring points. Utility Model Content
[0004] To address the issues mentioned above, where existing geomembranes are typically anchored directly to concrete structures, resulting in inadequate compaction of the geomembrane anchorage and potential leakage risks at the anchorage location if the sealing edges of the anchorage structure are not properly sealed, this invention provides a reinforced anchorage structure between the geomembrane and the surrounding concrete.
[0005] This utility model provides a geomembrane and surrounding concrete anchorage reinforcement structure, adopting the following technical solution:
[0006] A geomembrane and surrounding concrete anchoring reinforcement structure includes a concrete structure, a first geomembrane on the top of the concrete structure, a first anchoring structure between the right end of the first geomembrane and the concrete structure, a second geomembrane on the outside of the first anchoring structure, the bottom of the left end of the second geomembrane welded to the top of the first geomembrane, and a second anchoring structure between the right end of the second geomembrane and the concrete structure.
[0007] By adopting the above technical solution, the first geomembrane can be easily anchored to the concrete structure through the setting of the first anchoring structure, forming the first anchor. The second geomembrane can be easily anchored to the concrete structure through the setting of the second anchoring structure, and the second geomembrane is located outside the first anchoring structure. When there is a risk of leakage at the location of the first anchoring structure, the second geomembrane anchored through the second anchoring structure can still play a seepage prevention role, which greatly enhances the reliability of the anchoring structure.
[0008] Optionally, the first anchoring structure includes a stainless steel chemical bolt and a stainless steel angle steel. The stainless steel angle steel is sleeved on the upper end of the outside of the stainless steel chemical bolt. The first geomembrane is connected to the concrete structure through the stainless steel chemical bolt and the stainless steel angle steel. A first SR seepage-proof protective cover and an SR base coat are respectively provided between the top of the first geomembrane and the stainless steel angle steel, and the first SR seepage-proof protective cover is located above the SR base coat. From bottom to top, an SR base coat, an SR sliding layer, and an SR seepage-proof strip are sequentially provided between the bottom of the first geomembrane and the concrete structure.
[0009] By adopting the above technical solution, the first geomembrane can be anchored to the concrete structure. The stainless steel angle steel has high rigidity and the stainless steel chemical bolt has high anchoring force, so the anchoring force of the stainless steel chemical bolt can be evenly transmitted to the stainless steel angle steel, which can have good compressive properties for the first geomembrane.
[0010] Optionally, the second anchoring structure includes expansion bolts and stainless steel flat bars. The stainless steel flat bars are sleeved on the outside of the stainless steel chemical bolts. The second geomembrane is connected to the concrete structure through the expansion bolts and the stainless steel flat bars. A first SR seepage-proof protective cover and an SR base coat are respectively provided between the top of the second geomembrane and the stainless steel flat bars, and the first SR seepage-proof protective cover is located above the SR base coat. From bottom to top, an SR base coat, an SR sliding layer, and an SR seepage-proof strip are sequentially provided between the bottom of the second geomembrane and the concrete structure.
[0011] By adopting the above technical solution, the second geomembrane can be anchored to the concrete structure. The stainless steel flat bar has good flexibility and can be pressed more tightly. The expansion bolts are easy to install, resulting in good sealing of the anchoring structure.
[0012] Optionally, SR plastic filler and a second SR anti-seepage protective cover are respectively provided between the second geomembrane and the first anchoring structure, and the second SR anti-seepage protective cover covers the outside of the SR plastic filler.
[0013] By adopting the above technical solution, the first anchoring structure is wrapped with SR plastic filler under water pressure, which increases the anchoring reliability. At the same time, the second SR seepage-proof protective cover can prevent the stainless steel chemical bolts and stainless steel angle steel from piercing the second geomembrane under water pressure, thus increasing the safety of the second geomembrane.
[0014] Optionally, an elastic sealing agent is provided between the right end of the first anchoring structure and the concrete structure.
[0015] By adopting the above technical solution and sealing the edges with an elastic sealing agent, the sealing performance of the first anchoring structure and the second anchoring structure during anchoring is increased.
[0016] Optionally, several first anchoring structures are provided, and the spacing between adjacent first anchoring structures is 30 to 45 cm.
[0017] By adopting the above technical solution, the number of holes drilled on the surface of the concrete structure can be reduced, thus ensuring the reliability of the connection between the first geomembrane and the concrete structure.
[0018] Optionally, several second anchoring structures are provided, and the spacing between adjacent first anchoring structures is 20-30cm.
[0019] By adopting the above technical solution, the number of holes drilled on the surface of the concrete structure can be reduced, ensuring the reliability of the connection between the second geomembrane and the concrete structure.
[0020] In summary, this utility model has at least one of the following beneficial effects:
[0021] The first geomembrane is anchored to the concrete structure by the first anchoring structure to form the first anchoring. The second geomembrane is anchored to the concrete structure by the second anchoring structure, and the second geomembrane is set on the outside of the first anchoring structure. Even if there is a risk of leakage at the part of the first anchoring structure, the second geomembrane can still play a seepage prevention role, which greatly enhances the reliability of the anchoring structure.
[0022] The first geomembrane is anchored to the concrete structure by the cooperation of stainless steel chemical bolts and stainless steel angle bars. The stainless steel angle bars have high rigidity, and the stainless steel chemical bolts have high anchoring force, so the anchoring force of the stainless steel chemical bolts can be evenly transmitted to the stainless steel angle bars, which can provide good compressibility for the first geomembrane. At the same time, the spacing between adjacent stainless steel chemical bolts is 30-45cm, which reduces the need for drilling into the concrete structure and ensures the reliability of the connection between the first geomembrane and the concrete structure.
[0023] By welding one side of the second geomembrane to the first geomembrane, and anchoring the other side of the second geomembrane to the concrete structure using expansion bolts and stainless steel flat bars, the stainless steel flat bars have good flexibility and can be pressed more tightly, while the expansion bolts are easy to install, resulting in good sealing of the anchoring structure.
[0024] By setting SR plastic filler and second SR anti-seepage protective cover between the first anchoring structure and the second geomembrane, the SR material has good flexibility. Under water pressure, the SR plastic filler wraps around the first anchoring structure, increasing the anchoring reliability. At the same time, the second SR anti-seepage protective cover can prevent the stainless steel chemical bolts and stainless steel angle steel from piercing the second geomembrane under water pressure, thus increasing the safety of the second geomembrane.

[0029] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.
[0030] Please refer to the attached diagram in the instruction manual. Figure 1This utility model provides an embodiment of a geomembrane and surrounding concrete anchoring reinforcement structure, including a concrete structure 1. A first geomembrane 2 is provided on the top of the concrete structure 1. A first anchoring structure 14 is provided between the right end of the first geomembrane 2 and the concrete structure 1. The first anchoring structure 14 includes a stainless steel chemical bolt 8 and a stainless steel angle steel 10. The stainless steel angle steel 10 is sleeved on the upper end of the outside of the stainless steel chemical bolt 8. The first geomembrane 2 is connected to the concrete structure 1 through the stainless steel chemical bolt 8 and the stainless steel angle steel 10. A first SR seepage-proof protective cover 3 and an SR base adhesive 5 are respectively provided between the top of the first geomembrane 2 and the stainless steel angle steel 10, and the first SR seepage-proof protective cover 3 is located above the SR base adhesive 5. From bottom to top, an SR base adhesive 5, an SR sliding layer 7, and an SR seepage-proof strip 6 are provided between the bottom of the first geomembrane 2 and the concrete structure 1. This allows the first geomembrane 2 to be anchored to the concrete structure 1. The stainless steel angle steel 10 has high rigidity, and the stainless steel chemical bolts 8 have high anchoring force, ensuring that the anchoring force of the stainless steel chemical bolts 8 can be evenly transmitted to the stainless steel angle steel 10, providing excellent compressibility for the first geomembrane 2. Several first anchoring structures 14 are provided, with a spacing of 30-45 cm between adjacent first anchoring structures 14. This reduces the number of holes required on the surface of the concrete structure 1, ensuring the reliability of the connection between the first geomembrane 2 and the concrete structure 1.
[0031] Please refer to the attached diagram in the instruction manual. Figure 1 A second geomembrane 13 is provided on the outside of the first anchoring structure 14. SR plastic filler 4 and a second SR anti-seepage protective cover 16 are respectively provided between the second geomembrane 13 and the first anchoring structure 14, with the second SR anti-seepage protective cover 16 covering the outside of the SR plastic filler 4. Under water pressure conditions, the SR plastic filler 4 wraps around the first anchoring structure 14, increasing the anchoring reliability. Simultaneously, the second SR anti-seepage protective cover 16 prevents the stainless steel chemical bolts 8 and stainless steel angle steel 10 from piercing the second geomembrane 13 under water pressure, increasing the safety of the second geomembrane 13.
[0032] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2The bottom left end of the second geomembrane 13 is welded to the top of the first geomembrane 2. A second anchoring structure 15 is provided between the right end of the second geomembrane 13 and the concrete structure 1. The second anchoring structure 15 includes expansion bolts 9 and stainless steel flat bars 11. The stainless steel flat bars 11 are fitted over the outside of the stainless steel chemical bolts 8. The second geomembrane 13 is connected to the concrete structure 1 via the expansion bolts 9 and the stainless steel flat bars 11. A first SR seepage-proof protective cover 3 and an SR base coat 5 are respectively provided between the top of the second geomembrane 13 and the stainless steel flat bars 11, with the first SR seepage-proof protective cover 3 located above the SR base coat 5. From bottom to top, an SR base coat 5, an SR sliding layer 7, and an SR seepage-proof strip 6 are sequentially provided between the bottom of the second geomembrane 13 and the concrete structure 1. This allows the second geomembrane 13 to be anchored to the concrete structure 1. The stainless steel flat bars 11 have good flexibility and provide a tighter fit, while the expansion bolts 9 are easy to install, resulting in good sealing of the anchoring structure.
[0033] Please refer to the attached diagram in the instruction manual. Figure 1 Elastic sealing agent 12 is provided between the right ends of the first anchoring structure 14 and the second anchoring structure 15 and the concrete structure 1. Sealing with the elastic sealing agent 12 increases the sealing performance of the first anchoring structure 14 and the second anchoring structure 15 during anchoring. Several second anchoring structures 15 are provided, with a spacing of 20-30 cm between adjacent first anchoring structures 14. This reduces the number of holes required on the surface of the concrete structure 1, ensuring the reliability of the connection between the second geomembrane 13 and the concrete structure 1.
[0034] Working principle: In use, the foundation of the anchoring part of the first anchoring structure 14 is first ground flat, then SR primer 5 is applied, 10-15cm wide, followed by SR sliding layer 7, 10-15cm wide and about 6mm thick. Then SR anti-seepage strip 6 is laid on top, with the SR material side facing up, about 10cm wide and about 6mm thick. Then the first geomembrane 2 is laid in sequence, followed by SR primer 5 applied again. The first SR anti-seepage protective cover 3 is set on top of the SR primer 5. Then the first geomembrane 2 is anchored to the concrete structure 1 by stainless steel chemical bolts 8 and stainless steel angle steel 10. The stainless steel angle steel 10 has high rigidity and the stainless steel chemical bolts 8 have high anchoring force, so the anchoring force of the stainless steel chemical bolts 8 can be evenly transmitted to the stainless steel angle steel 10, which can have good compressive properties for the first geomembrane 2.
[0035] After the first geomembrane 2 is anchored, a second geomembrane 13 is added to the outside of the first anchoring structure 14. The foundation of the anchoring part of the second anchoring structure 15 is first ground smooth, and then SR primer 5 is applied, with a width of 10-15cm. Then, SR sliding layer 7 is laid, with a width of 10-15cm and a thickness of about 6mm. Then, SR anti-seepage strip 6 is laid on top, with the SR material side facing up, with a width of about 10cm and a thickness of about 6mm. Then, the second geomembrane 13 is laid in sequence, and then SR primer 5 is applied again. The first SR anti-seepage protective cover 3 is set on the top of the SR primer 5. Then, the second geomembrane 13 is anchored to the concrete structure 1 by expansion bolts 9 and stainless steel flat steel 11. Even if there are defects or weak parts in the first anchoring structure 14, the second geomembrane 13 can still play an anti-seepage role, which greatly enhances the reliability of the anchoring structure.
[0036] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
