Title:
INTERNAL-SPACE REINFORCING WALL SURFACE AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JP3939404
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain strong adhesion in a short time, and to prevent deterioration and falling from a wall surface by bonding and covering the steep-gradient wall surface between chambers in a tunnel with a sheet-shaped reinforcing layer by a cold radical reaction resin cured article and compounding the reinforcing layer and the cured article.
SOLUTION: When a sheet-shaped article is compounded with a wall surface containing sections having gradients of 45-315°, the foundation adjustment, primer coating and unevenness correction of the wall surface are conducted. The wall surface is coated with an adhesive, the sheet-shaped article is stuck, and an impregnant is applied and cured. When the sheet-shaped article is compounded, processes after the coating of the adhesive are repeated. A thixotropic-property imparting material is added to the adhesive and impregnant layer, and a composite sheet-shaped article is pasted and impregnation into the sheet is reinforced. An acrylic acid ester, a vinyl ester, etc., are used as a cold radical reaction resin. A fibrous article such as a carbon fibers, an aramid rein, etc., and the sheet-shaped article, etc., such as a metal, glass, etc., are employed as the reinforcing material of the resin.
