A thermosetting bamboo sand composite pressure pipe comprises a inner liner layer (1), an inner reinforcement layer (2), a sand adhesive layer (3), an outer reinforcement layer (4) and an outer protection layer (5) arranged respectively from an inside to an outside in a radial direction thereof. The inner reinforcement layer (2) formed by winding bamboo, a thickening layer (3) formed by stirred ore and adhesive, and the outer reinforcement layer (4) formed by winding bamboo are arranged sequentially from an inside to an outside between the inner liner layer (1) and the outer protection layer (5). The composite pressure pipe is energy-saving and environmental-friendly, raw production materials are recyclable, and a price is low.

1. A thermosetting bamboo-sand composite pressure pipe, the pressure pipe comprising: an inner liner layer and an outer protection layer arranged from inside out in a radial direction;an inner reinforcement layer formed by winding bamboo strips;a sand-adhesive thickening layer formed by an evenly blended mixture of ore sand and resin; andan outer reinforcement layer formed by winding bamboo strips,wherein the inner reinforcement layer, the sand-adhesive thickening layer, and the outer reinforcement layer are respectively disposed between the inner liner layer and the outer protection layer from the inside out in the radial direction,wherein in the inner reinforcement layer, the bamboo strips are first radially wound to form a first radial layer to adhere to an outer surface of the inner liner layer, and then the bamboo strips are axially wound to form a first axial layer to adhere to an outer surface of the first radial layer,in the outer reinforcement layer, the bamboo strips are first axially wound to form a second axial layer to adhere to an outer surface of the sand-adhesive thickening layer, and then the bamboo strips are radially wound to form a second radial layer to adhere to an outer surface of the second axial layer, andthe inner liner layer, the inner reinforcement layer, the sand-adhesive thickening layer, and the outer reinforcement layer are adhered and cured in an integrated manner by heating. 2. The pressure pipe of claim 1, wherein the bamboo strips of the inner reinforcement layer and the outer reinforcement layer have a length between 0.5 m and 2 m, a width between 5 mm and 10 mm, and a thickness between 0.3 mm and 1 mm. 3. The pressure pipe of claim 1, wherein the inner liner layer is formed by adhering a bamboo fiber nonwoven fabric to a needled bamboo mat by an adhesive, and a thickness of the inner liner layer is between 1.2 mm and 2.5 mm. 4. The pressure pipe of claim 1, wherein the outer protection layer is coated on an outer surface of the outer reinforcement layer, and a thickness of the outer protection layer is between 0.5 mm and 1.5 mm. 5. A thermosetting bamboo-sand composite pressure pipe, the pressure pipe comprising: an inner liner layer;an inner reinforcement layer adjacent to the inner liner layer, the inner reinforcement layer including first bamboo strips wound radially in a first radial layer and adhered to an outer surface of the inner layer, and second bamboo strips wound axially in a first axial layer and adhered to an outer surface of the first radial layer;a sand-adhesive thickening layer adjacent to the first axial layer, the sand-adhesive thickening layer being formed by an evenly blended mixture of ore sand and resin;an outer reinforcement layer adjacent to the sand-adhesive thickening layer, the outer reinforcement layer including third bamboo strips wound axially in a second axial layer and adhered to an outer surface of the sand-adhesive thickening layer, and fourth bamboo strips wound radially in a second radial layer and adhered to an outer surface of the second axial layer; andan outer protection layer,wherein the inner liner layer, the inner reinforcement layer, the sand-adhesive thickening layer, and the outer reinforcement layer are adhered and cured in an integrated manner by heating, andthe inner liner layer, the inner reinforcement layer, the sand-adhesive thickening layer, the outer reinforcement layer, and the outer protection layer are arranged from inside out in a radial direction. 6. The pressure pipe of claim 5, wherein the first and second bamboo strips of the inner reinforcement layer and the third and fourth bamboo strips of the outer reinforcement layer have a length between 0.5 m and 2 m, a width between 5 mm and 10 mm, and a thickness between 0.3 mm and 1 mm. 7. The pressure pipe of claim 5, wherein the inner liner layer is formed by adhering a bamboo fiber nonwoven fabric to a needled bamboo mat by an adhesive, and a thickness of the inner liner layer is between 1.2 mm and 2.5 mm. 8. The pressure pipe of claim 5, wherein the outer protection layer is coated on an outer surface of the outer reinforcement layer, and a thickness of the outer protection layer is between 0.5 mm and 1.5 mm.
