Undisturbed grouting plugging device under flowing water condition
The invention discloses an undisturbed grouting plugging device under the flowing water condition, and belongs to the technical field of grouting plugging, the undisturbed grouting plugging device comprises a grouting hose and a grouting floral tube connected with the grouting hose, a fixing seat is installed on the side, close to a grout outlet, of the grouting hose, the diameter of the fixing seat is larger than that of the grouting hose, and the grouting floral tube is connected with the grouting hose. The fixing seat is provided with an empty groove with an opening facing the grout outlet side, an annular piston plate is slidably mounted in the empty groove in a limited mode, the grouting hose penetrates through the annular piston plate and is connected with the annular piston plate in a sealed mode, and a first air hole communicated with the empty groove is formed in the fixing seat. An air bag communicated with the empty groove through a first air hole is installed on the peripheral wall of the fixing base, the grouting floral tube is provided with an installation cavity matched with the fixing base, and a sealing gasket is installed on the bottom wall of the installation cavity. The fixing base makes contact with the sealing gasket, the air bag expands in the grouting process and abuts against the inner wall of the mounting cavity, and slurry leakage is avoided.
本发明公开了一种动水条件下无扰动注浆封堵装置，属于注浆封堵技术领域，包括：注浆软管以及与注浆软管连接的注浆花管，所述注浆软管上靠近出浆口侧安装有固定座，所述固定座的直径大于注浆软管的直径，所述固定座设有开口方向朝向出浆口侧的空槽，所述空槽内限位滑动安装有环形活塞板，所述注浆软管穿过环形活塞板设置，且所述注浆软管与环形活塞板密封连接，所述固定座上设有与所述空槽连通的第一气孔，所述固定座周壁安装有通过第一气孔与空槽连通的气囊，所述注浆花管设有与所述固定座配合的安装腔，所述安装腔底壁安装有密封垫。本发明通过固定座与密封垫接触以及注浆过程中气囊膨胀，抵住安装腔内壁，避免浆料漏出。
