Problems solved by technology

[0011] The above-mentioned desalination improvement technologies for saline-alkali land can avoid the hazards of saline-alkali to varying degrees, prevent the increase of underground salinity, and achieve the improvement effect of salt washing and desalination. A device and method for improving saline-alkali land in 200810240783.5 and an engineering technology for improving saline-alkali land system with the application number 200510044210.1. Some of them have high work intensity and complicated construction links, and some have unreasonable structures of hidden pipes. Short lifespan leads to long treatment cycle and high treatment cost. It takes a long time to adhere to maintenance measures such as post-maintenance and management in order to achieve long-term salt and alkali control

Abstract

The invention discloses a saline discharge and alkali reduction concealed conduit device for saline-alkali soil. The saline discharge and alkali reduction concealed conduit device is characterized in that a dressing layer is arranged around the pipe walls of main pipes and branch pipes for forming a saline discharge and alkali reduction concealed conduit, the dressing layer consists of a water seeping layer formed by polyvinyl chloride (PVC) or poly ethylene (PE) granulation materials or ceramic particles with the granularity diameter being 0.5 to 0.8cm and the thickness being 10 to 15cm, a macadam and / or coarse sand layer with the thickness being 10 to 15cm is arranged above the dressing layer, the main pipes for forming the saline discharge and alkali reduction concealed conduit are distributed at intervals (L) being 30 to 40m and form the arrangement with the inclination being 3 to 5 degrees during pavement, the depth (H) from the top of an underground pipe network formed by the main pipes and the sub pipes to the ground is 80 to 100cm, a butt joint part is arranged in each position of the main pipe with the length being 30 to 50m, an inspection shaft is additionally arranged in each butt joint part or every two butt joint parts, and the length, the width and the depth of the inspection shaft are respectively 80 cm, 80cm and 120cm. The saline discharge and alkali reduction concealed conduit device has the advantages that the structure is simple, the formed structure of the underground pipe network is reasonable, the construction is convenient, the governing period is short, the cost is lower than that in the prior art, and the maintenance cost is avoided.

Description

(1) Technical field [0001] The invention relates to a soil improvement technique for saline-alkali land, in particular to a dark pipe device for discharging salt and reducing alkali in saline-alkali land. (2) Background technology [0002] Current methods used to improve saline land include: [0003] 1. Planting salt-alkali-tolerant crop varieties. According to the degree of salinization, plant varieties with strong salt tolerance are selected for planting. [0004] 2. Increase the application of organic fertilizers to improve the soil. Organic fertilizers can improve the soil aggregate structure, increase fertility, promote the soil improvement of the plow layer, reduce the salt content, and alleviate the negative impact of salinity (the aggregate structure makes the soil loose, cuts off the capillary pores of the soil, and increases the non-capillary pores, which is beneficial to prevent the salt of the groundwater from directly rise to the ground soil and concentrate, ...
