AI Technical Summary
Technical Problem
Existing culvert structures cannot effectively prevent the spread and explosion of liquid/gas leaks during oil and gas pipeline transportation, leading to potential safety hazards.
Method used
Semi-rigid energy-absorbing lightweight soil and flexible backfill sand are used as backfill materials, and a restraining steel mesh is arranged in the lightweight soil. Combined with waste gas and waste liquid collection devices and ignition devices, the leakage of flammable gas is absorbed and collected to limit its diffusion and explosion risk.
Benefits of technology
It effectively absorbs explosion energy, reduces harm, seals flammable gases, prevents their spread and explosion, and ensures safety.

Abstract
本发明公开了一种废气、废液收集吸能的盖板涵结构，废气收集吸能的盖板涵结构包括：吸能装置、废气收集装置、排气管和废气点燃装置；废液收集吸能的盖板涵结构包括：吸能装置和废液收集装置。本发明通过半刚性吸能轻质土与柔性回填砂，吸收爆炸产生能量，减小爆炸产生的危害，通过在管道上安装废气、废液收集装置在油气管道发生泄露时，将可燃气、液体密封在聚四氟乙烯预制件中，从而阻止可燃气体自由扩散；通过安装废气点燃装置、排气管限制可燃气体浓度，当体积浓度超过15％时点燃甲烷，使可燃气体安静燃烧，防止可燃气体发生爆炸。
