Abstract
A composite utility tunnel including a plurality of prefabricated tunnel units which are connected to one another. Each tunnel unit includes a tunnel body and a support component. The tunnel body includes a liner layer, a structural layer and an outer protective layer from inside to outside in the radial direction. The liner layer includes a flame-retardant resin and a flame-retardant fabric. The structural layer at least includes a plurality of bamboo strip layers including winding bamboo strips to which a water-soluble resin is adhered. The outer protective layer at least includes flame-retardant resin; and the support component is secured to an inner surface of the tunnel body.
