Abstract: An apparatus for tree protection and tree disaster prevention includes a plurality of supports that are provided with a predetermined spacing distance, a blocking part that is fixed by the plurality of supports, and a sealing support part that is interlocked and supported between the plurality of supports and inserted into the blocking part. The apparatus for tree protection and tree disaster prevention has effects of implementing ease of construction at a work site by uniformly and densely providing a plurality of through holes and increasing supporting force and resilience of the blocking wall, and enhance noise blocking, heat preservation, and shock absorption functions by manufacturing the blocking wall in the form of an air pocket.
