The invention discloses a coral sand improvement matrix, an improved coral sand and application thereof; the coral sand improvement matrix comprises modified water-absorbing fiber cotton, aluminosilicate, flocculant, coconut shell powder, soil structure stabilizer and bentonite. Modified coral sand includes coral sand modified substrate and coral sand. After the coral sand is modified by the modified matrix in the present application, the compactness of the coral sand is significantly improved. After the island is built with the modified coral sand as the island building material, it is beneficial to ensure the stability of the pile foundation, and the resulting improved Coral sand has excellent desalination performance and good water retention performance. The desalination performance can desalinate the infiltrating seawater, and then form fresh water that can be used by vegetation in the artificial island formation, which is conducive to promoting the formation of natural vegetation on the surface; the water retention performance can lock the infiltrated rainwater during rainfall, thereby accelerating the artificial island. Underground freshwater lens is formed to increase the underground freshwater content. The application of improved coral sand is conducive to promoting the formation of island reef freshwater ecosystems. |
