The structure of the primary anti-seepage bracket can be the same as that of the secondary anti-seepage bracket 4, or it can only include a corrugated extension module without the use of a support frame.

[0042] Exemplarily, the first-level beam anti-seepage membrane 9 is attached to the upper surface of the first-level anti-seepage bracket. The first-level beam anti-seepage membrane 9 is located between the shielding plate 446 and the U-shaped extension plate 441 on the first-level anti-seepage bracket, and is attached to the smoothing strip 448 and abutted against the pressing strip 447. The first-level beam anti-seepage membrane 9 and the first-level anti-seepage bracket form a first-level beam anti-seepage unit, and the second-level beam anti-seepage membrane 11 and the second-level anti-seepage bracket 4 form a second-level beam anti-seepage unit. The first-level beam anti-seepage unit and the second-level beam anti-seepage unit are combined with the upper concrete trough and the filling sand layer 10 to form an anti-seepage structure.

[0043] In the embodiment of the present invention, when the first-level beam road anti-seepage membrane 9 is matched with the first-level anti-seepage bracket, the first-level beam road anti-seepage membrane 9 is laid first, and its corresponding pressing strip 447 is first bent to make it deform through the weakening groove 449, and then the first-level beam road anti-seepage membrane 9 is laid on the upper surface of the first-level anti-seepage bracket, and placed between the shielding plate 446 and the U-shaped extension plate 441, so that the first-level beam road anti-seepage membrane 9 will fit with the smoothing strip 448, and the bent pressing strip 447 is released. After the pressing strip 447 rebounds through the rebound of the weakening groove 449, it will abut against the first-level beam road anti-seepage membrane 9. When the first-level beam road anti-seepage membrane 9 is pulled, the smoothing strip 448 and the pressing strip 447 will smooth the first-level beam road anti-seepage membrane 9. , guiding, when the pulling of the smoothing strip 448 stops, the pressing strip 447 will press the primary beam anti-seepage membrane 9, and when the secondary beam anti-seepage membrane 11 is coordinated with the secondary anti-seepage bracket 4, the secondary beam anti-seepage membrane 11 is laid first, and the secondary beam anti-seepage membrane 11 is attached to the upper surface of the secondary anti-seepage bracket 4, and the secondary beam anti-seepage membrane 11 is located between the U-shaped extension plate 441 and the smoothing limit unit 414, and between the shielding plate 446 and the U-shaped extension plate 441, and the secondary beam anti-seepage membrane 11 is attached to the smoothing strip 448 and abutted against the pressing strip 447, and combined with the working principle during the above pulling, the secondary beam anti-seepage membrane 11 is smoothed, guided and fixed during the pulling process.

[0044] When the fault zone is slightly squeezed or cracked, the first-level beam duct anti-seepage membrane 9 will extend along with the squeezing or cracking, and the U-shaped extension plate 441 will be squeezed or extended synchronously. During the process, the U-shaped extension plate 441 will be deformed by pulling or squeezing. When the fault zone is slightly displaced, the first-level beam duct anti-seepage membrane 9 will fluctuate along with it, and the U-shaped extension plate 441 will fluctuate along with the first-level beam duct anti-seepage membrane 9 when the first L-shaped slot 442 and the second L-shaped slot 443 are engaged.

[0045] When the fault zone is greatly squeezed, cracked and dislocated, through the above working principle, the secondary beam channel anti-seepage membrane 11 will extend or fluctuate with the squeezing and cracking, and at the same time, the U-shaped extension plate 441 will be squeezed, extended or fluctuated synchronously.

[0046] To accommodate upper concrete troughs of varying widths, multiple, sequentially detachably connected U-shaped extension plates 441 can be added to the B group extension modules. To accommodate fracture zones of varying widths, multiple, sequentially detachably connected U-shaped extension plates 441 can be added to the C group extension modules. To accommodate longer fracture zones or facilitate transportation and flexible adaptation, multiple, detachably connected U-shaped elastic plates can be added, detachably connecting the U-shaped elastic plates to the U-shaped extension plates 441.

[0047] The present invention provides a first-level beam channel anti-seepage membrane 9 and a second-level beam channel anti-seepage membrane 11, and adopts a curved laying method, which not only achieves double-layer anti-seepage, but also improves the ductility of the first-level beam channel anti-seepage membrane 9 and the second-level beam channel anti-seepage membrane 11, avoids the occurrence of anti-seepage structure tearing due to extrusion, cracking and dislocation folding of the fracture zone, and solves the problem of open channel seepage caused by anti-seepage structure tearing.

The first-level anti-seepage bracket and the second-level anti-seepage bracket 4 also enable the first-level beam duct anti-seepage membrane 9 and the second-level beam duct anti-seepage membrane 11 to be adapted for use in fracture zones of different widths and lengths, while avoiding folding, accumulation and bubbles during the laying process of the first-level beam duct anti-seepage membrane 9 and the second-level beam duct anti-seepage membrane 11, which affect their use. The first-level beam duct anti-seepage membrane 9 and the second-level beam duct anti-seepage membrane 11 can be bent plastically to enhance their ductility.
