Description

emergency drainage

technical field

The invention relates to the field of drainage equipment, in particular to an emergency drainage device.

Background technique

With the development of urban construction, more and more power distribution lines are laid underground, and more and more special box transformers for urban lighting are built in the underground space. The power distribution lines are transported to various street lights through underground cable channels. Below the pole, there is generally a special cable well channel near the underground box transformer or cable trench for maintenance or emergency operations.
