The utility model discloses an over-filling management device for a cast-in-place pile, and relates to the field of cast-in-place piles. When the cast-in-place pile over-filling management equipment is used, laitance, concrete grout and aggregate concrete are comprehensively distinguished by detecting the impedance of different media and the rotating speed of a front-end blade plate of the sensing module, real-time and accurate filling liquid level monitoring is achieved in the concrete filling process of the cast-in-place pile through comprehensive judgment of two sets of detection data, over-filling is avoided, and the service life of the cast-in-place pile is prolonged. The sensing module is simple in structure and low in cost, material resources and labor cost are saved, and detection electric power data are compensated, optimized and detected in real time through a temperature monitoring module in the sensing shell, so that impedance judgment of different media is more accurate. The rotating speed of a front-end vane plate of the sensing module is comprehensively judged through vane plate motor current value detection and rotating speed pulse value detection; the device can accurately detect the rotating speed of the vane plate in different medium environments, is simple in structure and convenient to operate, and brings a better use prospect.

This utility model belongs to the field of medical device technology, and particularly relates to a combination cap for infusion containers; it includes an outer cap, an inner cap, and a gasket disposed between the outer and inner caps; the outer cap is stepped, with multiple sealing valves at its top; the cavity formed by the combination of the outer and inner caps contains several liquid channels, and the gasket is disposed within the liquid channels; the gasket is pressed tightly into the liquid channels by the inner cap; a fixing mechanism is disposed on the outer cap to fix the infusion tubing and prevent it from shaking during use; an anti-shaking mechanism, through a locking mechanism, prevents unnecessary shaking of the infusion tubing during infusion, thereby maintaining a sealing effect. This utility model provides a combination cap for infusion containers that improves sealing performance and prevents loosening of the interface due to shaking of the infusion tubing.
