Device for quickly sealing pipe orifice of cast-in-situ bored pile post-grouting pipe
The invention provides a device for quickly sealing a pipe orifice of a cast-in-situ bored pile post-grouting pipe. The device comprises a fixed sleeve, a sliding sleeve, a rubber hose, a water passing pipe and a press grouting pipe, wherein the sliding sleeve is arranged below the fixed sleeve, the two ends of the rubber hose are connected to the opposite ends of the fixed sleeve and the slidingsleeve in a sleeving mode correspondingly, a water cavity is defined between the fixed sleeve and the sliding sleeve, the water passing pipe is arranged on the fixed sleeve in a penetrating mode, a water outlet of the water passing pipe communicates with the water cavity and is used for conveying water into the water cavity so as to enable the rubber hose to expand under the action of water pressure to abut against the grouting pipe to be sealed to block the grouting pipe to be sealed, the press grouting pipe is arranged in the fixed sleeve and the sliding sleeve in a penetrating mode, and a grout outlet of the press grouting pipe is formed below the sliding sleeve and used for grouting the grouting pipe to be sealed. According to the device, the rubber hose is arranged at the pipe orificeof the grouting pipe to be sealed and slightly expands to abut against the inner wall of the grouting pipe to be sealed to form a bottle plug, so that the pipe orifice of the grouting pipe to be sealed is quickly sealed.
本发明提供了一种钻孔灌注桩后注浆管快速封闭管口的装置，该装置包括：固定套；滑动套，其设置在固定套的下方；橡胶软管，其两端分别套设且连接在固定套和滑动套的相对端部上，在固定套和滑动套之间围设形成水腔；通水管，其穿设于固定套上，并且，通水管的出水口与水腔相连通，用以向水腔内输送水，以使橡胶软管在水压的作用下膨胀抵压在待封闭注浆管上实现待封闭注浆管的封堵；压浆管，其穿设于固定套和滑动套，并且，压浆管的出浆口设置在滑动套的下方，用以向待封闭注浆管内灌浆。本发明通过在待封闭注浆管管口处设置橡胶软管轻微膨胀顶住待封闭注浆管内壁形成“瓶塞”，以快速封闭住待封闭注浆管的管口。
