Abstract

The invention provides a method for concealed conduit salt discharging through underground cave storage. The method includes the steps of salt-discharging concealed conduit laying, wherein the burying depth of salt-discharging concealed conduits is 90 cm to 110 cm; wheat straw bundle making, wherein the diameter of wheat straw is 7 mm to 11 mm, and the moisture content of wheat straw is 32% to 35%; bundle burying and film covering, wherein the water injection rate of an underground cave is 4.0 Kg to 6.0 Kg. The invention also provides an application of the method for concealed conduit salt discharging through underground cave storage to saline-and-alkaline-land improvement; the concealed conduit salt discharging method is adopted, improvement is carried out for one year, the content of soil heavy mental is 9 ppm to 16 ppm.

Description

technical field [0001] The present invention relates to a method for removing salt through underground pipes and its application in the improvement of saline-alkali land, in particular to a method for using underground caverns to remove salt from underground pipes and its application in the improvement of saline-alkali land, which belongs to the rapid desalination and improvement of saline-alkali land technology field. Background technique [0002] According to incomplete statistics from UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. Draining and washing salt is one of the indispensable main measures for the treatment of saline-alkali land, following the natural law of "salt comes with water, salt goes with water". [0003] Underground pipe salt drainage technology is to lay a pipeline with pores at a certain depth underground, and the water that flows into the pipeline after irrig...
