摘要： The present invention is a waterproof sheet for a tunnel containing a base sheet containing a synthetic resin having on a surface thereof a silica-containing surface layer containing silica having a silicon dioxide content of 90% by mass or more in a ratio of from 30 to 200 mg/cm3, formed over a depth of from 5 to 30 μm from the surface of the waterproof sheet, and having a tensile breaking strength of 10 MPa or more and a mortar adhesion strength of 15 N/cm or more, and thus provides a waterproof sheet for a tunnel that forms no gap between the sheet and the concrete structure even when a prolonged period of time is elapsed from the installation, or the installed surface suffers large deterioration in evenness or levelness, ground subsidence or earthquake, and also does not cause problems including breakage and the like upon installation and after installation in the tunnel, thereby preventing smoothly water seeping from the earth or the ground from leaking into the tunnel.

摘要翻译： 本发明是一种用于隧道的防水片材，其包含含有合成树脂的基片，其表面上具有含二氧化硅的二氧化硅表面层，二氧化硅含量为90质量％以上，比例为30〜 200mg / cm 3，从防水片的表面形成5〜30μm的深度，拉伸断裂强度为10MPa以上，砂浆粘合强度为15N / cm以上，因此提供 用于隧道的防水片，即使在从安装中经过较长时间之后也不会形成片材和混凝土结构之间的间隙，或者安装的表面在均匀度或水平度，地面沉降或地震中遭受大的劣化，并且还 在安装和安装在隧道中时不会造成包括断裂等的问题，从而防止地球或地面的平滑的水渗入隧道。
