Concrete resistance value calibration device and calibration method for superfill monitoring system

Abstract

The concrete resistance value calibration device and its calibration method used in the overfill monitoring system belong to the technical field of overfill monitoring by the resistance value method, and are used to accurately calibrate the resistance value of concrete, and cooperate with the overfill monitoring intelligent system to give an alarm in time, so as to be more accurate control the height of concrete pouring. The system includes a probe, a detection tank and a motor. The electrical box is installed on the right side of the detection tank, and the motor or the manual crank drives the driving gear to rotate; the left probe is installed on the inner side of the left wall of the detection tank, and a The movable partition, the right probe is arranged on the left side of the movable partition, the right probe is set opposite to the left probe, the right side of the movable partition is fixedly connected with one end of the rack connecting rod, and the other end of the rack connecting rod It is fixedly connected with one end of the rack, and the other end of the rack penetrates the right side wall of the detection slot and the electrical box to mesh with the driving gear, and drives the movable partition to move horizontally in the detection slot along the guide rod through the gear transmission structure. The invention has the advantages of simple structure, sensitive measurement and the like.

Description

technical field [0001] The invention belongs to the technical field of overfill monitoring by resistance value method, and in particular relates to a concrete resistance value calibration device and a resistance value calibration method for an overfill monitoring system. Background technique [0002] The construction method of concrete pouring pile is low in cost and simple in operation, and has been widely used in water conservancy, highway, civil construction and other fields. In recent years, some researchers have developed different control devices to control the pouring height of concrete pouring piles. However, most of the devices are not reliable, and it is not convenient to recycle and reuse after pouring, and the use and maintenance costs are relatively high. [0003] The intelligent system for overfilling monitoring of cast-in-place piles based on the resistance value method can better solve this problem. This system is based on the characteristics of the obvious ...

AI Technical Summary

Problems solved by technology

[0004] A very important step in the monitoring method for overfilling of cast-in-place piles based on resistance values ​​is the calibration of concrete resistance values. If the calibration method is inaccurate, it will directly affect the correctness of the alarm value, thus bringing more difficulties to the control of the pouring height of concrete cast-in-place piles. Large error, can not achieve the purpose of preventing overfilling

At present, there is no specific calibration method in the operation process of the overfilling monitoring method based on the resistance value, which needs to be further optimized and perfected
