Device for monitoring concrete liquid level of cast-in-place pile in real time
The invention discloses a device for monitoring the concrete liquid level height of a cast-in-place pile in real time. The device comprises a support, a fixing support is installed on the support, a winch, an upper computer and a pile casing are installed on the fixing support, a fixed pulley is installed on the lower side of the outlet end of the pile casing, and a limiting block is installed on the upper side of the fixed pulley; one end of the measuring rope is connected with the measuring ball, and the other end of the measuring rope bypasses the fixed pulley and is connected with the winch; a stress-strain optical fiber and a transmission signal line are arranged in the measuring rope, and the transmission signal line is connected with an upper computer; the lower portion of the measuring ball is a solid portion, the upper portion of the measuring ball is a hollow portion, clear water is injected into the hollow portion, and the measuring ball density is adjusted by adding clear water. The monitor has the following advantages that the SMF-28e stress-strain optical fiber is adopted as a measurement and control unit, high sensitivity is achieved, the concrete liquid level elevation of the cast-in-place pile can be monitored in real time, and the problem of over-filling can be solved.
本发明公开了一种实时监测灌注桩混凝土液面高度的装置，包括支座，支座上安装有固定支架，固定支架上安装有卷扬机、上位机和护筒，护筒出口端下侧安装有定滑轮，定滑轮上侧安装有限动块；测绳一端与测球相连，另一端绕过定滑轮与卷扬机相连，上位机通过触发线与卷扬机下位机相连；测绳内部安装应力应变光纤和传输信号线，传输信号线与上位机连接；测球下部为实心部分，上部为空心部分，空心部分注清水，测球通过添加清水来调节测球密度。本发明监测仪具有如下优点：采用SMF‑28e应力应变光纤为测控单元，具有高灵敏度，能够实时监测灌注桩混凝土液面标高，有利于解决“超灌”问题。
