    • PROBLEM TO BE SOLVED: To provide techniques to strengthen a structural body such as a tunnel lining back face, for instance, a sprayed concrete on a slope face, an earth retaining wall, especially techniques to fill a filler into a cavity (void) like a tunnel lining back face, a cavity (void) formed between the sprayed concrete on a sloped face and a natural ground, a cavity (void) formed between an earth retaining wall and a natural ground, further, techniques to solve problems brought about in the cases of conventional air mortar or a foamed urethane as a filler, especially, problems of cracks or the like to be sealed in advance of the filling work, the problems of underground water pollution, problem having a fear of breakage of the structural body subjected to the water pressure of the back face. SOLUTION: An inorganic powder having pores in the inside is used as the filler to be filled in the cavity of a structural body back face. The inorganic powder having pores in the inside is a glass substance. COPYRIGHT: (C)2004,JPO&NCIPI
    • 要解决的问题:为了提供加强诸如隧道衬里背面的结构体的技术,例如在斜面上的喷射混凝土,挡土墙,特别是将填料填充到空腔中的技术( 空洞),形成在倾斜面上的被喷射的混凝土与自然地面之间形成的空腔(空洞),形成在土挡土墙和自然地面之间的空腔(空洞),还有解决问题的技术 在常规的空气砂浆或泡沫聚氨酯作为填料的情况下,特别是在填充工作之前要密封的裂缝等的问题,地下水污染的问题,担心破裂的问题 结构体受到背面的水压。 解决方案:将内部具有孔的无机粉末用作填充在结构体背面的空腔中的填料。 在内部具有孔的无机粉末是玻璃物质。 版权所有(C)2004,JPO&NCIPI
