This application discloses a system and method for measuring the depth of concrete surface during the construction of a seepage-proof wall, relating to the field of seepage-proof wall construction technology. The system includes a signal feedback line, a main connecting wire, and a calibration resistance line. The first end of the signal feedback line is electrically connected to the measuring contact of the display structure; the first end of the main connecting wire is electrically connected to the positive terminal of the display structure; and the first end of the calibration resistance line is electrically connected to the calibration contact of the display structure. The second ends of the signal feedback line, the main connecting wire, and the calibration resistance line are electrically connected, and all three are connected to a counterweight structure. The signal feedback line has multiple equally spaced depth sensing resistors. The display structure is used to display the depth of the concrete surface in the pouring trench in real time. The number of burst resistors is equal to the number of depth sensing resistors, and the burst resistors and depth sensing resistors are connected in parallel. The burst resistors have a breakable outer shell. This application measures the concrete surface depth by measuring resistance changes, achieving high accuracy, high construction efficiency, and cost savings.
