Problems solved by technology

[0005] (1) Poor temperature resistance;
[0006] (2) Poor flexibility at low temperature. Due to the low temperature in winter, the existing coiled hidden pipes have poor flexibility, high brittleness, and are easy to break when stretched.
[0007] (3) Poor pressure resistance and impact resistance;
[0008] (4) Easy to age and short service life

Abstract

The invention provides a ramie fiber salt elimination underground pipe used for saline-alkali soil. The underground pipe comprises, by weight, 26-38 parts of ramie fiber, 45-53 parts of modified polypropylene, 4-9 parts of phenyl alkyl-sulfonate, 0.6-1.8 parts of p-toluenesulfonhydrazide, 1.4-1.9 parts of calcium stearate, 4-11 parts of devulcanized rubber powder elastomers, 1-3 parts of petroleum-based hydrocarbon oil, 6-12 parts of nanometer titanium dioxide, 7-14 parts of silicone rubber, 5-13 parts of chlorinated polypropylene resin and 1-5 parts of sulfosalicylic acid. The invention further provides a preparation method of the underground pipe. The underground pipe has the advantages that the tolerated high temperature can reach 100-120 DEG C; the coil diameter reaches 12-15 meters under the low temperature of -50DEG C to -35 DEG C; the impact strength is 168-182 kJ / m<2>; the tolerant working pressure reaches 26-29 MPa, and the ring stiffness is 8-12 KN / m<2>.

Description

technical field [0001] The invention provides a ramie fiber salt-discharging concealed pipe for saline-alkali land and a preparation method thereof, belonging to the technical field of saline-alkali land improvement. Background technique [0002] The traditional saline-alkali land improvement technology is carried out by measures such as open ditch alkali drainage, large water pressure alkali drainage, and terrace alkali drainage. These measures generally use a large amount of fresh water, resulting in a shortage of water sources; the phenomenon of reverse osmosis of underground alkaline water is serious, and once the water is short of fresh water pressure irrigation, it will cause land salinization again, making it difficult to improve the saline-alkali land thoroughly. [0003] At present, the technology of underground pipe salt drainage is generally used to improve saline-alkali land, that is, through the buried pipe network buried under the soil layer of saline-alkali la...
