“…1, the x-axis represents the time, the y-axis represents the distance of the pile top from the ground, and S0 and S1 represent the height of the pile top after the stabilisation of two consecutive hammers, respectively. at the moment of t0, the hammer core strikes the pile top and forces the pile to sink, and at the time of reaching the lowest point of the curve, the pile will rebound due to the elastic damping effect of the soil on the pile and this rebound effect will be a small amplitude of the bouncing for a finite number of periods, and finally reaches the stabilisation value of S1 [10][11] , ΔS is the penetration value. Therefore, in the collected pile vibration signal, extract the corresponding S0 and S1 values, and the difference between the two can be obtained penetration.…”

This paper designs a device for measuring the penetration depth of pile driving on construction sites in response to problems such as high subjectivity and ineffective recording in traditional penetration depth detection. The device uses a laser ranging sensor for non-contact measurement of the pile body, filters the vibration signal through a microprocessor, extracts the effective penetration depth, displays it on the human-computer interaction interface, records the penetration depth data via an SD card, and sends the data to a server via WiFi. This device replaces manual measurement, enabling more scientific and standardized measurement of penetration depth, timely notifying workers to stop hammering when the penetration depth meets the stopping criteria. Field experiments show that the accuracy of the device's hammeringstop prompt is 96.90%, and its detection has high standardization and meets user needs, improving construction efficiency.

Based on the pure bending orthogonal test of different diameter grouting micro circular steel pipe, the influence of the parameters such as steel ratio, steel yield strength, the type and strength of filling material on the bending performance of the grouting steel pipe pile was simulated by the finite element software. The results show that the error between the ultimate bearing capacity of the cast-in-place steel pipe pile simulated by the finite element method and the test data is between 6.4% and 13.6%, which is in good agreement and can be used for simulation calculation; under the pure bending action, the steel content of the cast-in-place steel pipe component has a great influence on its bearing capacity; the yield strength of the steel pipe has a significant effect on improving the bending bearing capacity of the micro steel pipe pile; the filling core material of the steel pipe The influence of strength on flexural capacity is less, so the core filling material with low compressive strength can be used to reduce the investment.
