Buried type high-pressure water channel or tunnel seepage-resistant lining structure

[0008] The present invention will be further described below in conjunction with the drawings.

[0009] See figure 1 An anti-seepage steel pipe 1 is provided in the high-pressure pipeline section or high-pressure bifurcated pipe section 4, and leveling or backfill concrete 3 is arranged between the outer wall of the anti-seepage steel pipe 1 and the high-pressure pipe section or the high-pressure bifurcated pipe section 4. The inner wall is provided with reinforced concrete lining 2.

[0010] See figure 1 , By installing a certain thickness of reinforced concrete lining 2 in the anti-seepage steel pipe 1 to share the internal water pressure acting on the anti-seepage steel pipe 1 on the outer layer of reinforced concrete, so as to reduce the thickness of the anti-seepage steel pipe 1, and at the same time use the reinforced concrete lining 2 It has good compressive performance, resists the external water pressure transmitted through the outer steel pipe, completely avoids the occ...
