Description

Technical Field

[0002] According to Chinese Patent No. CN211240739U, a salt-isolating and drainage structure for saline-alkali land includes a planting soil layer at a higher elevation in the saline-alkali land. A 40cm thick gravel layer is laid horizontally within the planting soil layer. A first non-woven fabric layer is laid on top of the gravel layer. A 5cm diameter PVC pipe is installed 10cm from the bottom of the gravel layer, with a 3‰ slope within the gravel layer. The end of the PVC pipe connects to a low-lying area or a drainage ditch. Drainage holes with a diameter of 1cm are opened every 50cm on the side of the PVC pipe. A second non-woven fabric layer wraps around the outside of the PVC pipe. This salt-isolating and drainage structure for saline-alkali land can effectively reduce soluble salts in the planting soil, lower soil salinity, prevent salt and alkali from harming plants, improve the survival rate of salt-intolerant plants, and enhance tree growth.

[0003] The aforementioned prior art and related documents have the following technical problems:

[0004] 1. If a section of a complete PVC pipe becomes blocked, the entire pipe needs to be repaired, which is costly and inconvenient to maintain.

[0005] 2. Relying solely on natural gravity filtration results in a slow treatment process. Utility Model Content

[0014] Beneficial effects

[0015] In this invention, a locking buckle is used to connect the salt drain pipe and it is fixed with ground-inserted anchors. This allows for quick assembly and disassembly. The locking buckle structure allows for connection or separation without tools, facilitating regular cleaning of salt crystals. In case of failure, individual pipe fittings can be replaced without disassembling the entire pipeline, saving costs. The locking buckle structure with no dead angles at the interface reduces salt solution retention. Combined with regular backflushing, it can reduce the risk of scaling at the interface.

The water pump can be used to control the water flow to ensure the normal operation and effective desalination of the desalination system. At the same time, by adjusting the speed and pressure of the water flow, it can help clean the desalination pipes. In addition, in saline-alkali land that urgently needs to be treated, the water pump can accelerate the treatment process and restore the saline-alkali land to usability as soon as possible.
