Technical Field

[0001] This utility model belongs to the field of utility tunnel engineering maintenance, and in particular relates to a utility tunnel engineering maintenance system. Background Technology

[0002] Currently, utility tunnel projects involve many concrete construction procedures, and all concrete construction requires curing. Curing is usually carried out by manually laying geotextiles and other water-retaining materials, plus intermittent manual watering.
