Abstract

The invention provides a good-pressure-resistance salt elimination concealed pipe for saline and alkali soil. The concealed pipe comprises, by weight, 50-55 parts of polyethylene, 18-20 parts of polycarbonate, 15-19 parts of fatty alcohol phosphate ester, 1-3 parts of sodium bicarbonate, 2.3-3.5 parts of rock wool, 1.2-1.9 parts of nano calcium oxide powder, 2.5-4.2 parts of butadiene styrene rubber, 5-7 parts of alkyd resin, 5.2-6.9 parts of isothiazolinone and 0.8-1.3 parts of calcium ricinoleate. The concealed pipe is a corrugated pipe, the nominal outside diameter is 112 mm, and the wall thickness is 5 mm. Water inflow holes are formed in the concealed pipe and are oval, and according to the ovality, the ratio of the maximum outer diameter to the minimum inner diameter is not larger than 120%. The number of the water inflow holes on the same circumference is three. Every three water inflow holes are evenly distributed at the interval of 120 degrees, and the overall water inflow area is 38 cm <2>/m. The concealed pipe is high in pressure resistance, good in thermal tolerance, and the deformation ratio of the concealed pipe is low.

Description

technical field [0001] The invention belongs to the field of improvement of saline-alkali land, and relates to a salt-discharging concealed pipe for saline-alkali land, in particular to a salt-discharging concealed pipe for saline-alkali land with good pressure resistance and an application thereof. Background technique [0002] Due to the accumulation of a large amount of salt in the saline-alkali land, it causes a series of soil deterioration, sticky structure, poor air permeability, high bulk density, serious compaction, poor microbial activity in the soil, and aggravated salinization; it has a serious impact on plant growth, and the soil in coastal saline-alkali land contains salt High water flow, high groundwater table, high soil pH, low organic matter content; high wind speed, large evaporation, and high groundwater salinity. Therefore, the primary problem of saline-alkali land greening is how to improve the soil as soon as possible, solve the problem of salt content i...
