Problems solved by technology

[0004] The traditional measure of salinization and alkali removal is usually to replace the soil, but for coastal areas, the replacement soil is likely to return to alkali with the movement of water and salt

Embodiment Construction

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] In describing the present invention, it is to be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "surrounding" etc. Indicating orientation or positional relationship is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as limiting the present invention .

[0029] Such as Figure 1 to Figure 3 Shown, a kind of seaside green land salinity discharge construction technology, comprises the following steps:

[0030] S10. Excavating the original soil, digging out the original soil in the green area planting area to form a planting pit 1, a...

Abstract

The invention relates to a coastal greenbelt salt and alkali elimination construction process. The process includes steps: S10, original oil excavation; S20, blind ditch excavation; S30, salt elimination well construction; S40, blind ditch paving; S50, isolating layer paving; S60, salt and alkali elimination leaching layer paving; S70, planting soil backfilling. The process has advantages that according to a water-salt movement law that the salt comes along with water, goes away along with water, ascends along with water and descends with water, saline-alkali soil can be improved by paving ofa salt and alkali elimination leaching layer and laying of coarse sand and salt elimination pipes; in the rainy season, salt in soil flows into the salt elimination pipes along with water in rainfall,and salt ascending along with water in water evaporation in the dry season can be prevented through gravel grass mats and the like, so that alkali returning of discharged saline-alkali water due to water level rise can be effectively prevented, salt-containing underground water is prevented from ascending along capillary gaps of soil, the underground water is controlled below a critical depth, and soil salt elimination and salt returning prevention are realized.

Description

technical field [0001] The invention relates to the field of soil treatment of saline-alkali land, in particular to a construction process for draining salt-alkali in coastal green land. Background technique [0002] In recent years, the coastal area has become an important position for the development of my country's "blue economy", and the study of improved greening technology for coastal saline-alkali land is of great significance to urban construction and development. In saline-alkali land greening projects in coastal areas, the improvement effect of saline-alkali land is directly related to whether plants can survive and whether the soil quality can meet the needs of plant growth for a long time, which is the decisive factor for the success of the project. [0003] There are many unfavorable factors for landscaping in saline-alkali land. The main contradiction is that the soil contains too much soluble salt. [0004] The traditional measure of salinization and alkali r...
