[0035] A using method of a grooving sampling device includes the following steps:

[0036] The first step: Determine the cutting parameters according to the rock strength, joint development, integrity degree and sample size requirements, including the cutting depth and the cutting angle;

[0037] The second step: According to the sampling design, draw guiding lines on both sides of the prospecting drift and the approach with paint. The guiding lines include two upper and lower ones;

[0038] The third step: Use a special grooving cutting device for construction sampling. Cut from top to bottom. First, use the device to cut its upper part to be cut (1-1). After the upper part is cut, rotate the cutting device 180° parallel to the rock surface. After adjusting the height, then use the device to cut its lower part to be cut (1-2). After cutting is completed, the geological personnel use the flat side of the geological hammer head to put the trapezoidal or triangular sample into the upper cutting seam, use the lever principle to pry off the sample, and then load it into the lithology box. Wait until it is transported to the surface and use the lithology splitting device to divide it into two parts. One half is used for analysis and testing, and the other half is retained for subsequent research.

[0039] The cutting device consists of a housing, a cutting machine, a cutting machine fixing frame, and a sliding device. The housing is rectangular as a whole, with two angle adjustment scales 2-1 arranged front and back, and 4 fixing parts 2-2 arranged on each side for connecting the cutting device and the moving device into one body. Screw holes 2-3 are reserved on the fixing parts 2-2. A cutting slot 3-1 is arranged at the lower part of the housing. During operation, one side of the cutting slot is aligned with the upper and lower guiding lines on the object to be cut. The cutting machine fixing frame is connected to the housing through a fixing device 3-2 arranged at the bottom of the housing. The cutting machine fixing frame consists of an angle adjustment rod 3-3, a frame body 3-4, and two slide rails 3-5. The outside of the angle adjustment rod 3-3 is threaded, and the angle of the cutting machine fixing frame is fixed by using a fixing nut 2-4, thereby fixing the angle of the cutting machine. The cutting machine is fixed by a tubular fixing part 3-6 through a fixing screw 3-7. Two sliders 3-8 are arranged on both sides of the tubular fixing part and are connected to the slide rails. The tubular fixing part 3-6 is connected to a telescopic rod 3-9, and the telescopic rod 3-9 provides pressure to enable the cutting machine to smoothly cut a groove. A pressure sensor 3-10 is installed between the tubular fixing part 3-6 and the telescopic rod 3-9 to control the pressure. The pressure sensor 3-10 transmits the pressure to the pressure controller 3-11 at the rear end. When the pressure is too high, the telescopic rod 3-9 stops power supply and locks, and when the pressure is too low, the telescopic rod 3-9 extends.

[0040] The moving device has upper and lower layers. Four horizontal bubble levels 6-2 and four fixing parts 6-3 matching the fixing parts on the housing are arranged on the upper layer plate 6-1. A spring group 6-4 and 3-4 connecting rods 6-5 are arranged between the upper and lower layers. The outside of the spring group 6-4 is protected by a cloth cover 6-6.
