Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, in particular to a drainage pipeline crossing device for municipal engineering. Background Technique

[0002] The drainage pipeline crossing in municipal engineering refers to the opening part used for rainwater and sewage discharge in the municipal road drainage system. It is a key component connecting the drainage pipeline and the underground drainage system. The design and construction of the drainage pipeline crossing are crucial for the effectiveness and safety of the entire drainage system.

[0003] After a large number of searches, the publication number is CN212104471U, which discloses a drainage pipeline crossing device for municipal engineering. By respectively and movably installing a sliding block on the left and right parts of the mounting plate, and movably connecting a pulling rod to the upper end of the sliding block, the cover plate can be lifted more labor-savingly. By setting a filter plate, larger sundries can be effectively prevented from entering the drainage pipeline, avoiding the blockage of the drainage pipeline.

[0004] When the device in the prior art is in use, the closing plate needs to be opened first, and then the pulling rod can be exposed, and the cover plate is lifted through the pulling rod. However, when the above device is in use, it is usually in an outdoor environment. At this time, once dead branches and fallen leaves enter the sliding groove, the closing plate cannot be effectively closed. When a vehicle runs over the cover plate, it will damage the vehicle tires. At the same time, when the light is dim, it is also easy to trip pedestrians, so there are certain safety hazards in use. For this reason, a drainage pipeline crossing device for municipal engineering is needed to solve the above problems. Content of the Utility Model
