INJECTION NOZZLE FOR PINNING METHOD AND PINNING METHOD USING THE SAME
To provide an injection nozzle and the like for a pinning method, which can efficiently inject an adhesive in accordance with the properties such as the quantity and occurrence locations and the like of "floating part" that occurs on a wall body.SOLUTION: An injection nozzle 12 for a pinning method to inject an adhesive R into a prepared hole 8 drilled to a predetermined depth on an external wall 1 while sealing an opening 8a of the prepared hole. The injection nozzle comprises: a first nozzle port 32 facing a deep part of the prepared hole 8; a second nozzle port 56 facing the vicinity of the opening 8a of the prepared hole 8; a first adhesive duct 61 in communication with the first nozzle port 32; a second adhesive duct 62 in communication with the second nozzle port 56; and a second on-off valve mechanism 67 that opens and closes only the second adhesive duct 62.SELECTED DRAWING: Figure 3
【課題】壁体に生ずる「浮き部」の数や発生個所等の性状に合わせて、接着剤を効率良く注入することができるピンニング工法用の注入ノズル等を提供する。【解決手段】外壁１を所定の深さまで穿孔した下穴８に、その開口部８ａを封止しながら接着剤Ｒを注入するピンニング工法用の注入ノズル１２であって、下穴８の奥部に臨む第１ノズル口３２と、下穴８の開口部８ａ近傍に臨む第２ノズル口５６と、第１ノズル口３２に連通する第１接着剤流路６１と、第２ノズル口５６に連通する第２接着剤流路６２と、第２接着剤流路６２のみを開閉する第２開閉弁機構６７と、を備えたものである。【選択図】 図３
