Description

Technical Field

[0001] The utility model belongs to the technical field of saline-alkali land treatment, and in particular relates to salt-isolating bricks for convenient splicing of saline-alkali land treatment. Background Art

[0002] Saline-alkali land is a type of land where salts accumulate. Various soluble salts are redistributed horizontally and vertically on the ground, so that salt gradually accumulates on the soil surface, forming a salt-accumulating area. The soil in saline-alkali land is compacted, and the high salt content in the soil interferes with crop growth, making it impossible to cultivate crops near saline-alkali land. At present, the traditional way to improve saline-alkali land is generally to drain and wash salt to reduce the salt content of the soil, then plant salt-tolerant plants to fertilize the soil, and finally plant crops.

[0003] In order to prevent salt and alkali from penetrating with water, which will increase the salt content of the treated saline-alkali land, existing research has proposed that a row of salt-isolating bricks be piled between the treated saline-alkali land and the untreated saline-alkali land to separate the saline-alkali land and prevent the salt from the untreated saline-alkali land from penetrating with water into the treated saline-alkali land. Currently, the most common salt-isolating bricks are mainly hollow bricks, which can drain the saline-alkali water.

[0004] For example, a salt-isolating brick for saline-alkali land treatment is disclosed in a patent document with announcement number CN206323758U and announcement date July 14, 2017, including a brick body, the brick body is a hollow uncovered cubic structure, the brick body includes side walls and a bottom surface, a partition is provided inside the brick body, one end of the partition is connected to the top of one side wall, and the other end is connected to the bottom of the other side wall opposite to the side wall. Usually, the salt-isolating brick is a rectangular brick, and this salt-isolating brick for saline-alkali land treatment is usually used by stacking and laying. However, after the salt-isolating brick for saline-alkali land treatment is stacked, there are still gaps at the joints of adjacent salt-isolating bricks. If the salt-isolating brick is used for a long time, saline-alkali water will penetrate into the gap, resulting in poor effect of separating saline-alkali land. Utility Model Content
