System for monitoring and pre-warning pile foundation damage in real time

The invention discloses a system scheme for monitoring pile foundation damage in real time and providing early warning. In the scheme, a sensor (2) for monitoring the pile foundation damage is arranged on a pile foundation (1), driven into the ground together with the pile foundation, led out through a lead (3) and connected to a signal acquisition device (4). Through the system, real-time monitoring of the pile foundation damage can be realized. The system has two functions, namely in the building construction process, the system can be used for accurately judging the pile driving quality of the pile foundation and providing early warning for the damage produced in the pile driving process; and in the building using process, the system can be used for monitoring the safety of the pile foundation in real time, providing early warning signals in time and sending the monitoring results in wired and wireless manners.
