Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of railway engineering, in particular to a railway corrugated pipe with damping function. BACKGROUND

[0002] As a key stress compensation and protection component in track engineering, the railway corrugated pipe is widely used in railway subgrade drainage systems, cable sleeves and bridge expansion joints, etc. Its damping performance is directly related to the long-term stability and operation safety of the track structure. With the extension of high-speed railway network to complex geological areas, the corrugated pipe needs to maintain structural integrity under the coupling action of continuous dynamic load, temperature difference deformation and chemical corrosion, which puts strict requirements on the energy dissipation capacity and interface adaptability of the material.

[0003] In the prior art, traditional corrugated pipes are mostly made of single-layer metal or polymer structures. The homogeneous material design leads to linear conduction of vibration energy along the pipe body, making it difficult to achieve shock wave attenuation through gradient impedance matching, especially in the frequently occurring microseismic area, fatigue crack propagation is easy to occur. Although some improved schemes add a rubber interlayer to improve the buffering performance, the insufficient interfacial adhesion strength between the layers can easily cause delamination failure, and the lack of directional energy absorption mechanism leads to low broadband damping efficiency. The existing pipe docking system mostly relies on flanges and bolt fastening, and the rigid connection mode is difficult to compensate for the concentricity deviation between pipes of different diameters, and is easy to cause sealing failure under thermal expansion and cold contraction conditions, and manual adjustment of the clamp positioning is time-consuming and labor-intensive, which restricts the large-scale railway maintenance efficiency. Therefore, there is an urgent need for a railway corrugated pipe with damping function to break through the technical bottleneck of weak anti-seismic performance and poor construction adaptability of traditional products.
