[0042] The primary beam channel anti-seepage unit of the embodiment of the present invention comprises a corrugated primary anti-seepage bracket and a primary beam channel anti-seepage membrane 9; the primary beam channel anti-seepage membrane 9 is fixed to the upper surface of the primary anti-seepage bracket. The structure of the primary anti-seepage bracket may be the same as that of the secondary anti-seepage bracket 4, or may only comprise a corrugated extension module without using a support frame.

[0043] Exemplarily, the first-level beam road anti-seepage membrane 9 is attached to the upper surface of the first-level anti-seepage bracket, the first-level beam road 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 road anti-seepage membrane 9 and the first-level anti-seepage bracket form a first-level beam road anti-seepage unit, the second-level beam road anti-seepage membrane 11 and the second-level anti-seepage bracket 4 form a second-level beam road anti-seepage unit, the first-level beam road anti-seepage unit and the second-level beam road anti-seepage unit are combined with the upper concrete trough and the filling sand layer 10 to form an anti-seepage structure.

[0044] 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 it is placed between the shielding plate 446 and the U-shaped extension plate 441, so that the first-level beam road anti-seepage membrane 9 and the smoothing strip 448 are fitted together, 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 duct anti-seepage membrane 9, and when the secondary beam duct anti-seepage membrane 11 cooperates with the secondary anti-seepage bracket 4, the secondary beam duct anti-seepage membrane 11 is laid first, and the secondary beam duct anti-seepage membrane 11 is attached to the upper surface of the secondary anti-seepage bracket 4, and the secondary beam duct 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 duct 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 duct anti-seepage membrane 11 is smoothed, guided and fixed during the pulling process.

[0045] 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.

[0046] When the fault zone is greatly squeezed, cracked and displaced, through the above working principle, the secondary beam channel anti-seepage membrane 11 will extend or fluctuate with the squeezing and cracking, and the U-shaped extension plate 441 will be squeezed, extended or fluctuated synchronously.

[0047] When it is necessary to adapt to upper plate concrete troughs of different widths, multiple U-shaped extension plates 441 that can be detachably connected in sequence can be added to the B group extension module. When it is necessary to adapt to fracture zones of different widths, multiple U-shaped extension plates 441 that can be detachably connected in sequence can be added to the C group extension module. When it is necessary to adapt to longer fracture zones or to facilitate transportation and flexible adaptation, multiple detachably connected U-shaped elastic plates can be added, and the U-shaped elastic plates and the U-shaped extension plates 441 can be connected in a detachable manner.

[0048] The present invention not only realizes double-layer anti-seepage by arranging a primary beam duct anti-seepage membrane 9 and a secondary beam duct anti-seepage membrane 11 and adopting a curved paving method, but also improves the ductility of the primary beam duct anti-seepage membrane 9 and the secondary beam duct anti-seepage membrane 11, avoids the occurrence of anti-seepage structure tearing due to extrusion, cracking and dislocation folding of the fault zone, and solves the problem of open channel seepage caused by anti-seepage structure tearing.

[0049] The present invention not only increases the structural strength and service life of the first-level beam-way anti-seepage membrane 9 and the second-level beam-way anti-seepage membrane 11 by providing a first-level anti-seepage bracket and a second-level anti-seepage bracket 4, but also further improves the anti-seepage effect, and avoids the occurrence of water seepage due to traction damage during use. The first-level anti-seepage bracket and the second-level anti-seepage bracket 4 also allow the first-level beam-way anti-seepage membrane 9 and the second-level beam-way 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-way anti-seepage membrane 9 and the second-level beam-way anti-seepage membrane 11, which affect the use, and can bend the first-level beam-way anti-seepage membrane 9 and the second-level beam-way anti-seepage membrane 11 to enhance their ductility.
