INJECTION NOZZLE FOR PINNING METHOD, AND PINNING METHOD USING THE SAME
To provide an injection nozzle for pinning method capable of preventing a first nozzle part constituting a first injection channel from sticking to a hole wall of a base hole while maintaining the second injection channel.SOLUTION: An injection nozzle includes: a nozzle body 22 having adhesive channels 61, 62 therein; an aperture sealing part 23 attached to the tip of the nozzle body 22; a first nozzle part 24 that extends from the nozzle body 22 through the opening sealing part 23 to the forward direction, and has a first injection channel 33 that communicates with the adhesive channel 61 therein; a second nozzle part 25 that has a second injection channel 55 communicating with the adhesive channel 62 in the gap between the nozzle part 24 and the opening sealing part 23; and a nozzle holder 64 that holds the first nozzle part 24 coaxially with the second nozzle part 25.SELECTED DRAWING: Figure 3
【課題】第２注入流路を維持しつつ、第１注入流路を構成した第１ノズル部が下穴の穴壁につかえるのを抑制することができるピンニング工法用の注入ノズルを提供する【解決手段】 内部に接着剤流路６１，６２を有するノズルボディ２２と、ノズルボディ２２の先端部に取り付けられた開口封止部２３と、ノズルボディ２２から開口封止部２３を貫通して先方に延び、内部に接着剤流路６１に連通する第１注入流路３３を有する第１ノズル部２４と、第１ノズル部２４と開口封止部２３との間隙に接着剤流路６２に連通する第２注入流路５５を有する第２ノズル部２５と、第１ノズル部２４を、第２ノズル部２５と同軸上に保持するノズル保持部６４と、を備えたものである。【選択図】 図３
