Abstract:
     The present invention relates to a pile-meassuring apparatus equipped with the device capable of synchronously amplifying signals with time function. It is mainly characterized by that the pile-measuring apparatus is equipped with a device capable of real-time and synchronously amplifying signals according to the attenuation law of reflection signals of pile-foundation defect or pihe bottom or in accordance with the preset time function relationship. Said apparatus consists of binary programmable amplifier, data latch, function-storage device, address conuter, data I/O interface, read-write and chip-selecting controller, signal amplitude discrimination device and logic decoder. The storage value of said function-storage device can be set by CPU under the control of software according to the the time function relationship, and then the synchronized signal is given out by signal amplitude discrimination device.
