    • PROBLEM TO BE SOLVED: To provide a construction method for solidifying vegetation greening sand preventing wind erosion to enable vegetative greening even in an area lack of rich underground water and suffered from gusty wind erosion, and excellent in construction property and economical efficiency. SOLUTION: The construction method for hardening vegetation greening sand comprises spraying a vegetative greening composition containing seeds, fertilizer, a water-holding agent and a fertilizer-holding agent on the surface of the desert, spraying an aqueous solution for solidification composed of hydrophilic polyurethane resin and water so as to form a solidified porous sand layer. The thickness of the porous sand layer is 5-50 mm, and the concentration of the hydrophilic polyurethane resin in the aqueous solution for solidification is 2-7 wt.%. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:提供一种施工方法,用于固化防止风蚀的植被绿化沙,使得即使在缺乏丰富的地下水的地区也能营造绿化,遭受阵风风蚀,建筑性能和经济效益优良。 解决方案:植被绿化固化施工方法包括在沙漠表面喷洒含有种子,肥料,保水剂和肥料保持剂的营养绿化组合物,喷洒固化水溶液,由 亲水性聚氨酯树脂和水,以形成固化的多孔砂层。 多孔砂层的厚度为5-50mm,凝固水溶液中的亲水性聚氨酯树脂的浓度为2-7重量%。 版权所有(C)2009,JPO&INPIT
