Sleeve grouting compactness detection method
The embodiment of the invention discloses a sleeve grouting compactness detection method, and particularly relates to the technical field of sleeve grouting. The method comprises the following steps of: 1, welding a plurality of reinforcing steel bars in a sleeve. The sleeve grouting compactness is detected by adopting a vibration signal transmission mode, a vibration generator needs to be mountedon one side of the sleeve before action, a vibration signal receiver is mounted on the other corresponding side, in a vibration transmission process, a vibration signal is gradually weakened, especially when passing through air, the vibration transmission signal is greatly reduced, in a detection process, the vibration generator on one side needs to be started firstly, through the transfer of grouting in the sleeve, the signal can reach the vibration signal receiver on the other side, the sleeve grouting compactness is judged according to the strength of the vibration signal, the weaker the received vibration signal is, the smaller the sleeve grouting compactness is, and the larger the number of internal air holes is, so that the sleeve grouting compactness can be precisely detected. Thedetection method is easy to operate and accurate in detection.
本发明实施例公开了一种套筒灌浆密实度检测方法，具体涉及套筒灌浆技术领域，包括以下步骤：步骤一：在套筒的内部焊接若干根钢筋。通过采用震动信号传递的方式来检测套筒灌浆密实度，在进行前，需要将震动发生器安装在套筒的一侧，而对应的另一侧安装震动信号接收器，在震动传递的过程中震动信号会逐渐减弱，尤其是通过空气时，大大降低震动的传递信号，在检测过程中，需要先将启动一侧的震动发生器，通过套筒内灌浆的传递，到达另一侧的震动信号接收器，根据震动信号的强弱来判断套筒灌浆密实度，接收到的震动信号越弱，说明套筒灌浆密实度越小，内部的气孔数量越多，从而可以精确的检测套筒灌浆密实度，本发明检测方法操作简单，检测精确。
