Technical Field

[0001] This utility model relates to the field of maintenance well technology, specifically a maintenance well structure suitable for cable tunnel ventilation. Background Technology

[0002] Cable tunnels are generally laid under sidewalks on roads. They are shallowly buried, equipped with openable covers (for ventilation during installation and maintenance), and do not require lighting or ventilation equipment. They are widely used in urban construction due to their low cost.

[0003] However, in some old urban areas, due to insufficient total road width and sidewalk width not meeting the requirements for cable tunnel layout, cable tunnels can only be laid under motor vehicle lanes and cannot be equipped with openable covers (using a closed structure). Ventilation and heat dissipation are problems. If ventilation facilities are set up as a trunk and branch integrated utility tunnel, the cost will increase significantly. Therefore, a maintenance well structure suitable for cable tunnel ventilation is proposed to solve the ventilation and heat dissipation problems with minimal additional cost. Utility Model Content
