Abstract | The utility model relates to the field of pipeline engineering in municipal engineering, and discloses a small-caliber water and gas conveying pipeline structure crossing a highway and railway foundation, which comprises a water and gas conveying pipeline, an elastic cushion layer is wrapped on the outer side of the water and gas conveying pipeline, and an outer protective sleeve is arranged on the outer side of the elastic cushion layer; the length of the outer protection sleeve is not smaller than that of the elastic cushion layer, sealing plugs are arranged at the two ends of the outer protection sleeve, and the elastic cushion layer is sealed in a closed space formed by the water and gas conveying pipeline, the outer protection sleeve and the sealing plugs. Through the buffering effect of the elastic cushion layer, vibration loads generated when vehicles pass through are counteracted, fatigue damage of the vibration loads generated by the vehicles on the road to the water conveying pipeline is reduced, th |
