The side wall of the drill rod 1 is abutted with the rotating mechanisms 4, and in the embodiment, two rotating mechanisms 4 are symmetrically arranged on two sides of the drill rod 1 in order to improve the measurement accuracy. The drill rod 1 moves up and down to drive the rotating mechanism 4 to rotate synchronously, the metering instrument 5 on the rotating mechanism 4 sends rotating data of the rotating mechanism 4 to the control device, and the control device is mainly used for calculating all data and automatically controlling all components to act cooperatively.

Slewing mechanism 4 includes a plurality of saw-tooth gyro wheels 7 of evenly installing on dwang 6, and the different directions of saw-tooth orientation of two adjacent saw-tooth gyro wheels 7, saw-

tooth gyro wheel

7 and 1 butt of drilling rod, saw-tooth gyro wheel 7 can adopt high strength saw-tooth gyro wheel, guarantees to be unlikely to make the gyro wheel diameter change because of mud is too much in the use, and the saw-tooth gyro wheel 7 of high strength also can durable wear-resisting, uses after a period, can directly wash. In the specific embodiment, dwang 6 is installed on support piece 8, and support piece 8's width is greater than drilling rod 1 diameter for when drilling rod 1 promoted or transfers the in-process to appear shaking, sawtooth gyro wheel 7 on the support piece 8 all can adapt to. Seven sawtooth gyro wheels 7 are no less than evenly installed to dwang 6, and in this embodiment, seven sawtooth gyro wheels 7 are evenly installed to dwang 6. The measuring instrument 5 is installed to 8 lateral walls of support piece, and 6 tip of dwang are connected with measuring instrument 5, and measuring instrument 5 sends the rotation volume of dwang 6 that detects often to controlling means in, and controlling means receives back analysis and processing.

the test of the standard penetration and the dynamic detection is finished in the last time, the drilling tool 3 in the hole is extracted, and then the standard penetration device or the dynamic probe and a plurality of drill rods are immediately put down to the bottom of the hole. Therefore, after the drill-down is completed, the current depth, namely the depth of the original position test starting point is obtained, then the driller presses the standard penetration/dynamic detection button, the equipment starts to measure, the depth is recorded every time the drill-down is performed in the test process, the penetration times are recorded at the same time, meanwhile, the standard penetration/dynamic detection data are automatically calculated by a software system embedded in the matched receiving instrument, and when the standard penetration/dynamic detection data meet the standard requirement and can not be performed any more, the indicating lamp flickers to prompt the driller to stop the test. After the test is completed, the driller presses the completion indexing/probing test button, and the equipment stops measuring indexing/probing data. After the penetration/movement is completed, the penetration/movement probe needs to be lifted out of the hole, and the process is similar to the drilling lifting work and is not described again.

The measured error of the drilling depth of the device can be controlled within about 0.3 percent, and the test data recorded by the marking and dynamic probing automatically is consistent with the manual counting.

The drilling depth, the standard penetration and the dynamic exploration data are wirelessly transmitted in an instrument terminal held by a driller team descriptor or driller, and are uploaded to a cloud platform by clicking one key after a single or a plurality of drilling final holes. The test data corresponds to the actual test time and can not be modified by the drill team, so that the problem of field description counterfeiting is avoided.
