The reinforced layer includes a bamboo fiber reinforced layer and a straw reinforced layer. The bamboo fiber reinforced layer includes a plurality of bamboo strip layers. Each bamboo strip layer includes winding bamboo strips. The straw reinforced layer includes a plurality of straw layers. Each straw layer includes winding stems of straw.

Composite pipe and method for manufacturing the same

A hemp-winding composite pipe including a lining layer, a reinforcement layer winding on the lining layer, and an external protective layer, in that order from the inside to the outside in the radial direction. The reinforcement layer is a hemp bast layer, including continuously connected hemp basts.

Hemp-winding composite pipe

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.
