REINFORCEMENT METHOD OF MASONRY RETAINING WALL
To provide a reinforcement method of a masonry retaining wall with excellent appearance which can rigidly connect a masonry retaining wall to a sloped natural ground while effectively forming a hardened layer of an urethane foam in a gap in back-filling cobble stone.SOLUTION: A head storing recessed portion 12 with a predetermined depth is formed at a predetermined place in wedge stones 4 becoming a masonry retaining wall 2. A drilling rock bolt 20 drills from a bottom portion of the head storing recessed portion 12 to a predetermined depth reaching a sloped natural ground 10. A head portion of the drilling rock bolt 20 is made to remain in a drilled hole 14 so as not to protrude to an outside from the head storing recessed portion 12. After a hardened layer of an urethane foam 34 is formed around the drilled hole 14, a caulking material is filled into the head storing recessed portion 12, and the head portion of the drilling rock bolt 20 is embedded in a caulking portion 44, to be fixed to the masonry retaining wall 2 where the head storing recessed portion 12 is formed.SELECTED DRAWING: Figure 3
【課題】裏込めグリ石の隙間にウレタン発泡体の硬化層を効果的に形成しつつ、傾斜地山に対する、石積擁壁の連結を強固に行ない得るように構成すると共に、景観に優れた石積擁壁の補強工法を提供する。【解決手段】石積擁壁２となる間知石４の所定箇所に所定深さの頭部収容凹所１２を形成し、この頭部収容凹所１２の底部から、傾斜地山１０に達する所定深さまで穿孔ロックボルト２０を穿孔させて、かかる穿孔ロックボルト２０の頭部が頭部収容凹所１２から外部に突出しないように、穿孔１４内に残留せしめ、穿孔１４の周囲にウレタン発泡体３４の硬化層を形成した後、頭部収容凹所１２にコーキング剤を充填して、穿孔ロックボルト２０の頭部を、コーキング部４４内に埋没させ、頭部収容凹所１２の形成されている石積擁壁２に固定せしめるようにした。【選択図】図３
