Embodiment

[0040] Example: An improved greening construction method for saline-alkali land, the specific steps are as follows:

[0041] S1: Clean and level the site, first remove the salt mud, garbage and weeds on the surface, and then excavate the saline-alkali soil according to the depth, width and flatness required by the design to form a green belt. The salt mud content in the surface layer of the saline-alkali soil is basically saturated, and all the salt mud is excavated and transported out, which can not only eliminate the saline and alkali, but also prevent the garbage and impurities in the salt mud from affecting the soil flow effect of the green belt.

[0042] If the surface of the construction site is uneven, it is necessary to lay a 30cm gravel layer, and then backfill the alkaline soil to form a level site, enhance the structural strength of the site, and then pave the soil layer to avoid a collapse in the green belt due to the unstable underlying alkaline soil.

[0043] S2: Lay ou...

Abstract

The invention discloses a construction method for improvement and greening of a saline-alkali land. The construction method comprises the following concrete steps: S1, land cleaning and leveling; S2,setting-out; S3, salt-discharge ditch digging; S4, gravel backfilling for salt-discharge ditches, and slope formation; S5, alkali discharge pipe laying; S6, salt-alkali discharge isolation layer laying; S7, peripheral salt-alkali soil isolation; S8, greening planting soil backfilling; S9, salt-discharge inspection well construction; and S10, greening construction. According to the invention, in virtue of cooperation of an alkali-discharge pipe, a drainage open channel and an isolation layer, separation of alkaline soil from planting soil is realized; the salt in the alkaline soil is avoided from being raised into the planting soil; and in virtue of cooperation of a first sleeve drum and a second sleeve drum, cleaning of the soil surrounding the alkali-discharge pipe is realized, and the blockage of the alkali-discharge pipe is avoided.

Description

Technical field [0001] The invention relates to the technical field of saline-alkali land improvement, and more specifically, it relates to an improved greening construction method for saline-alkali land. Background technique [0002] At present, land salinization is a worldwide problem facing mankind. There are large areas of salinized land in China, which are mainly distributed in the North China Plain, the Northeast Plain, the inland areas of the Northwest and the coastal areas. The survival rate of plants planted in saline-alkali land is generally very low, which seriously affects my country's agricultural and forestry production. [0003] Publication No. CN106171104A, Publication Date 20161207 discloses a method for flat plowing and deep ploughing and applying desulfurized gypsum to improve saline-alkali land. The method for flat plowing and deep ploughing and applying desulfurized gypsum to improve saline-alkali land. The specific steps are as follows: S1: the ratio of improv...
