Description

Technical Field

[0001] The utility model relates to the technical field of pipe trench covers, in particular to a ventilation pipe trench cover with a self-contained drainage system. Background Art

[0002] Pipeline trenches are mainly used to safely bury various pipelines under the surface, such as hydrogen, natural gas, LNG and other pipelines; and the pipeline trenches need to be covered with trench covers to protect the underground pipelines from the external environment and provide passage for pedestrians and vehicles. The most commonly used cover is the perforated cover.

[0003] A new type of ditch cover with publication number TWM289162U is mainly composed of two cover sets, and a support frame is set inside the two, and the drain holes on the cover are avoided, and the support frame is used as a support. However, the drainage is the same as the traditional perforated cover. The rainwater will flow into the ditch along the drain holes on the cover, and then an appropriate slope is set in the ditch to make the rainwater flow into the special drainage pipe and then into the collection pool. This method is not only cumbersome to construct and requires a large investment, but also easy to cause pipeline corrosion. For this reason, we provide a ventilated ditch cover with its own drainage system to solve the above problems. Utility Model Content
