Embodiment 1

[0029] see Figure 1-8 As shown, the present invention is a salt discharge structure for restoration and treatment of coastal saline-alkali land, including a solid foundation revetment 1, a salt washing pipe 2, a circulation well 3 and an infiltration pipe group, wherein the solid foundation revetment 1 and the infiltration pipe group are both Buried in the soil layer of the saline-alkali land to be repaired, the circulation well 3 is set up in the offshore of the saline-alkali land, the solid foundation revetment 1 is set in the offshore of the saline-alkali land, and the salt washing pipe 2 is set on the surface of the saline-alkali land; the infiltration pipe group includes the high-permeability pipe 4 And the low-permeability pipe 5, wherein the high-permeability pipe 4 is installed below the low-permeability pipe 5, and both are communicated with the circulation well 3; the salt washing pipe 2 is installed above the low-permeability pipe 5, and is communicated with the cir...

Embodiment 2

[0034]In order to deal with the desalinated water on the surface of the saline-alkali land and the soil of the planting layer above, the infiltration pipe group also includes two confluence boxes 6, and the two confluence boxes 6 are respectively bolted and communicated with several high-permeability pipes 4 and several low-permeability pipes 5, and each infiltration The infiltration water of the tube group is collected and collected, and the eluted salt is deposited; the confluence box 6 and the circulation well 3 are bolted and communicated with a confluence pipe 601 .

Embodiment 3

[0036] In order to cope with the short-term rise of the groundwater level and balance the distribution of moisture and salt in the soil, a number of electro-hydraulic rods 1011 are installed on the lower surface of the connecting beam 101, and the electro-hydraulic rods 1011 extend to the inside of the revetment pipe 102; the output ends of the electro-hydraulic rods 1011 are welded There is a hydraulic plate 1012, and the hydraulic plate 1012 and the inside of the revetment pipe 102 form a piston structure; the inside of the revetment pipe 102 is provided with a piezoelectric valve 1023 and a sliding rod 1024, wherein the piezoelectric valve 1023 and the sliding rod 1024 are socketed, and the two are slidably matched The piezoelectric valve 1023 is welded with the inner surface of the revetment pipe 102; the buoy plate 1025 is welded on the lower end surface of the slide rod 1024, and the baffle plate 1026 is welded on the upper end surface; the piezoelectric valve 1023 is elec...

Abstract

The invention discloses a salt-discharging structure used for restoration and treatment of coastal saline-alkali land, and relates to the technical field of soil restoration and treatment. The invention includes solid foundation revetment, salt washing pipe, circulation well and infiltration pipe group, wherein the solid foundation revetment and infiltration pipe group are buried inside the soil, the salt washing pipe is arranged on the surface, and the salt washing pipe and infiltration pipe group are both Connected with circulation well. The present invention combines the internal seepage pipe with the coastal revetment structure by setting the solid foundation revetment and the infiltration pipe group, while quickly and efficiently performing soil salt discharge restoration on the coastal saline-alkali land, and can also use the solid foundation revetment to stabilize the coastal foundation; wherein, The infiltration pipe group is mainly used to infiltrate groundwater and lower the groundwater level, while the salt washing pipe and circulation well can irrigate and desalt the planting layer of saline-alkali land, and make the salt in the planting layer discharge into the circulation well with the water flow for salinization. The desalinated water in the circulation well is used again for irrigation and desalination, which can quickly restore the coastal saline-alkali land.

Description

technical field [0001] The invention belongs to the technical field of soil remediation and management, and in particular relates to a salt discharge structure used for the remediation and management of coastal saline-alkali land. Background technique [0002] Salinization is a phenomenon of land salt accumulation, which usually affects the growth of crops due to the high salt content in the soil; usually the formation of saline-alkali land is inseparable from the influence of climate, geographical conditions and water flow systems, especially coastal saline-alkali land, Also known as coastal saline-alkali land, it is often formed due to the erosion of coastal soil by the high-salt environment of seawater, which has great harm to the coastal crop economy; Strong plants can be used for restoration, such as the invention patent (CN105908693B), which discloses a planting blanket used for soil improvement of muddy coastal saline-alkali land. Although it has a good effect on rest...
