Embodiment 1

[0045] The bamboo is processed into multiple bamboo strips according to the following two specifications. The size of the first bamboo strip is set to be 1500m in length, 8mm in width, and 0.5mm in thickness. The moisture content can be selected as 10%. The specifications and sizes of the two kinds of bamboo strips are set as 20mm in length, 6mm in width and 1mm in thickness, and the moisture content can be selected as 10%, and then they are treated by degreasing, cleaning and dehydration for later use.

[0046] Then, the above-mentioned first bamboo strips are overlapped one by one along their lengths, and simultaneously arranged in parallel along their width (for example, 6 bamboo strips), finally forming a total length of 150m, a width of about 48mm, and a gap between adjacent bamboo strips. The gap area is 0.09cm 2 In addition, the above-mentioned second bamboo strips are overlapped one by one along the width direction, and the final weaving form has a total length of 150m...

Embodiment 2

[0051] The bamboo is processed into multiple bamboo strips according to the following two specifications. The size of the first bamboo strip is set to be 2000m long, 8mm wide, and 0.5mm thick. The moisture content can be selected as 15%. The specifications and sizes of the two kinds of bamboo strips are set to be 20mm long, 10mm wide, and 0.5mm thick, and the moisture content can be selected as 15%, and then they are degreased, cleaned and dehydrated for later use.

[0052] Then, the above-mentioned first bamboo strips are overlapped one by one along their lengths, and simultaneously arranged in parallel along their width (for example, 6 bamboo strips), finally forming a total length of 150m, a width of about 48mm, and a gap between adjacent bamboo strips. The gap area is 0.12cm 2 In addition, the above-mentioned second bamboo strips are overlapped one by one along the width direction, and the final weaving form has a total length of 150m and a width of 20mm, and the gap area ...

Embodiment 3

[0057] The bamboo is processed into multiple bamboo strips according to the following two specifications. The size of the first bamboo strip is set to be 2500m long, 4mm wide, and 1mm thick. The moisture content can be selected as 15%. The size of the bamboo strips is set as 40mm in length, 4mm in width, and 1mm in thickness, and the moisture content can be selected as 15%, which is then degreased, cleaned and dehydrated for later use.

[0058] Then, the above-mentioned first bamboo strips are overlapped one by one along their lengths, and simultaneously arranged in parallel along their width (for example, 10 bamboo strips), finally forming a total length of 150m, a width of about 40mm, and a gap between adjacent bamboo strips. The gap area is 0.25cm 2 In addition, the above-mentioned second bamboo strips are lapped one by one along the width direction, and the final weaving form has a total length of 150m and a width of 40mm, and the gap area between adjacent bamboo strips is...

Abstract

The invention belongs to the related field of composite tubes, and discloses an ultra-large-diameter bamboo winding composite tube. The bamboo winding composite tube comprises a lining layer, a composite strengthening layer and an outer protection layer from inside to outside, and the lining layer is made of fiber blankets or non-woven fabrics with anticorrosive resin in an adhesion manner; the composite strengthening layer is formed in a manner that two different types of bamboo skin curtains are wound outside the lining layer in a layer-by-layer manner according to the proper layer number and the thickness proportion wholly in the ring direction, the bamboo skin curtains are sprayed with the resin in a liquid-leaching manner while winding is carried out, and then bonding curing is carried out; and the outer protection layer is cured on the outer surface of the strengthening layer in a coating manner, and the effects of water prevention, corrosion prevention, radiation prevention and the like are achieved. The invention further discloses a corresponding manufacturing method. Through the ultra-large-diameter bamboo winding composite tube and the manufacturing method, even under the tube diameter obvious expanding condition, the characteristic that the whole structure of the bamboo winding composite tube is free of stress distribution defect can be well kept, and meanwhile comprehensive properties of pressure resistance, ring stiffness, long-term use quality stability and the like can be obviously improved.

Description

technical field [0001] The invention belongs to the technical field related to composite pipes, and more specifically relates to a super-large diameter bamboo winding composite pipe and a manufacturing method thereof. Background technique [0002] At present, various types of pipes are widely used in many industries at home and abroad. Traditional pipes are mainly divided into metal pipes (such as seamless steel pipes, ductile cast iron pipes, etc.), plastic pipes (such as PVC pipes, HDPE pipes, etc.), cement pipes, and glass steel pipes (such as sand-filled glass steel pipes). Different performance characteristics, but also present different advantages and disadvantages: for example, seamless steel pipe has high pressure bearing capacity, high temperature resistance, easy processing, but heavy weight, easy corrosion, difficult construction and average service life; HDPE pipe is light in weight, durable Corrosion, easy to process, but poor temperature resistance and pressur...
