Abstract

The invention discloses a sensing type fixed pulley testing system for monitoring a dynamic compaction operation process and a method of the sensing type fixed pulley testing system. The system comprises a ring code fixed pulley and a logic controller, wherein a ring of annular bar codes is arranged on the inner wall of the ring code fixed pulley, a code scanner scans the bar codes to read the number of turns of the ring code fixed pulley and an angle between any two bar code locations, wherein the angle is accurate to 0.5 degree; the shaft of the ring code fixed pulley is a matched shaft pin type force measuring sensor which is fixed on a support arm through a bolt to measure the pressure born by a wheel axle of the ring code fixed pulley in real time; the logic controller receives and processes real-time data from the shaft pin type force measuring sensor and the code scanner to be calculated and output to a display, so that the display can display the drop distance, the hammer weight and the tamping energy, and when requirements are not met, an alarm gives an alarm to monitor the dynamic compaction construction quality in real time.

Description

technical field [0001] The invention relates to a sensor-type fixed pulley testing system and a method thereof for monitoring a dynamic compaction operation process, and is especially suitable for monitoring the self-weight, drop distance and tamping times of a rammer in the dynamic compaction operation process. Background technique [0002] The dynamic compaction method is to lift a heavy hammer (8-40 tons) with a diameter of 1-3 meters to a certain height (6-30 meters), let it fall freely, and use the impact energy of the falling weight to power the soil. Tamping is a soil reinforcement method to increase its compactness and strength and reduce its compressibility. The dynamic compaction method is widely used in the reinforcement treatment of subgrades and foundations because of its simple equipment, convenient construction operation, wide range of applicable soil properties, fast construction speed, and low construction cost. [0003] The reinforcement effect of the dyna...
