TWIN TUBE TYPE CHEMICAL INJECTION DEVICE AND CHEMICAL INJECTION METHOD USING IT
To arbitrarily select 1 to 2 shots according to the request, especially in the case of 1 shot or 1.5 shots, perform simultaneous injection into 2 injection areas.SOLUTION: A chemical injection device comprises an injection tube 2 and two tip monitors 3 and 4 inserted into the injection tube 2. The injection tube 2 comprises an inner tube 5 and an outer tube sleeve 6 mounted in close contact with an outer peripheral surface of the inner tube 5. The inner tube 5 comprises one outer inner tube 8 that surrounds the whole in a cross-sectional view, and two tubular inner tubes 9A and 9B arranged in parallel in the outer inner tube 8, and comprises one or a plurality of inner tube discharge ports 10a and 10b. The outer tube sleeve 6 is made of a material that can be deformed in the cross-sectional expansion/contraction direction, and includes outer tube discharge ports 6a and 6b at predetermined intervals in the tube longitudinal direction. The tip monitors 3 and 4 are insertable into the tubular inner tubes 9A and 9B, have outlets 3a and 4a for injection materials, and are provided with packer portions 11 and 12 at vertical positions thereof.SELECTED DRAWING: Figure 3
【課題】要求に応じて１ショット〜２ショットまでを任意に選択でき、特に１ショット又は１．５ショットの場合は２箇所の注入領域に対しての同時注入を可能とする。【解決手段】注入管２と、この注入管２に挿入される２本の先端モニター３、４とから構成される。前記注入管２は、内管５と、この内管５の外周面に密着した状態で装着された外管スリーブ６とからなり、前記内管５は、断面視で全体を囲繞する１つの外形内管８と、この外形内管８内に並列配置された２つのチューブ状内管９Ａ、９Ｂとからなり、１又は複数の内管吐出口１０ａ、１０ｂを備える。前記外管スリーブ６は、断面拡縮方向に変形可能な材料によって構成され、管長手方向に所定の間隔で外管吐出口６ａ、６ｂを備える。前記先端モニター３、４は、前記チューブ状内管９Ａ、９Ｂに挿入可能とされ、注入材の流出口３ａ、４ａを有するとともに、その上下位置にパッカー部１１、１２を備えている。【選択図】図３
