CRASHED OLIVINE SOIL AND METHOD OF CONSTRUCTING PLAYGROUND USING THE SAME

摘要

PURPOSE: An olivine crushed soil and a playground construction method using thereof are provided to improve water permeability and hydrous by including proper sized olivine particles. CONSTITUTION: An olivine crushed soil comprises a plurality of olivine pieces with particle diameter of 0.001-6mm. A playground construction method comprises next steps: uniformly installing gravel with particle diameter of 13-25mm and planarizing in order to form a first base layer(L1); installing the gravel with the particle diameter of 10-13mm on top end portion of the first base layer and planarizing a second base layer(L2); installing olivine crushed soil which a plurality of olivine pieces with particle diameter of 0.002-5.8mm are mixed on top end portion of the second base layer in 120mm thickness and planarizing in order to form a third base layer(L3); spraying soil stabilizer over the base layer and planarizing after 72 hours; Installing olivine crushed soil which a plurality of olivine with particle diameter of 0.002-3.2mm is mixed on top end portion of the third base layer in 10-12mm thickness; and planarizing in order to form a surface layer(L4).
