[0002] The cast-in-place concrete pile is a widely used pile foundation form. To eliminate the weakening of the bearing capacity caused by the bottom sediment and side mud skin of the pile, the pile bottom and side grouting processes are often adopted to improve the vertical bearing capacity of a single pile. The pile bottom and side grouting are carried out by burying grouting pipes. The grouting pipes are tied to the steel reinforcement cage and the top is exposed above the ground. The outer diameter of the grouting pipe is usually ∮32 or ∮50. Usually, 2 - 3 grouting pipes are provided for each pile. The top end of the grouting pipe exposed above the ground is usually a thread, which is connected to the female joint of the grouting hose of the grouting machine for grouting.
[0003] When the existing connection joint is connected, since the external installation pipe needs to be installed, the user needs to manually or with the help of an external support to support the connection joint, which is time-consuming and laborious. Then, the joint and the installation pipe are installed by means of knocking installation. However, this installation method not only requires the user to limit the connection joint and the installation pipe, but also causes the grouting pipe and the threaded end to be unable to be effectively connected during connection, and is liable to cause the jacking pipe to be squeezed and bent, etc. Eventually, the grouting pipe and the grouting hose cannot be connected, and then the grouting operation cannot be carried out, which is not convenient for use and increases the installation workload of the user. Therefore, we have proposed a self-tightening connection joint device for grouting pipes and sonic logging pipes, which has the function of being convenient for use and is urgently to be developed.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] When the existing connecting joint is connected, since it is necessary to install the external installation pipe, the user needs to manually support the connecting joint or use an external bracket to support it, which is time-consuming and laborious. Then, the joint and the installation pipe are installed by means of knocking and installation. However, this installation method not only requires the user to limit the connecting joint and the installation pipe, but also causes the grouting pipe and the threaded end to be unable to be effectively docked during connection, and is prone to problems such as the jacking pipe being squeezed and bent. Eventually, the grouting pipe and the grouting hose cannot be connected, and then the grouting operation cannot be carried out, which is not convenient to use and increases the installation work burden of the user. Therefore, through research, the inventor provides a self-tightening connecting joint device for grouting pipes and acoustic logging pipes. By setting the auxiliary installation component, it plays the role of connecting and contacting the joint device and the installation pipe. Specifically, the fixing plate drives the installation block, the limiting plate, the round rod and the sliding rod to move towards the connecting pipe until the sliding rod contacts and clamps the connecting pipe, thus completing the installation and support effect. And after installation, the joint device can also be installed by knocking, and the stability during installation is improved, avoiding the situation of position deviation during installation, improving the accuracy during installation, being convenient to use, and thus solving the above defects.
