abstract
The utility model discloses a device for detecting the pouring depth of cast-in-place pile concrete. It comprises a probe hammer (1), a force sensor (2) and a signal receiving alarm (3); The probe hammer (1) is vertically installed on the lower side of the surface of concrete (10/) poured in the pile hole (6) of the cast-in-place pile through a pull wire (1 1), and the other end of the pull wire (1) is connected with the weighing sensor (. The signal receiving alarm (3) is located on the ground; The signal receiving alarm (3) is communicated with the weighing sensor (2) through a signal line (3 1). The use of this device can save a lot of concrete, reduce the workload of pile cutting in the later period, improve the construction efficiency, reduce the construction cost and reduce the labor intensity of workers. The device is simple in structure, easy to install and operate, and suitable for popularization and application.
