[0002] The main construction methods for roadbed stone excavation are mechanical method and blasting method. Although mechanical method is fast and relatively safe, it is expensive. In blasting excavation, the risks of explosive material transportation and on-site construction are relatively high, but the on-site construction is mostly controlled blasting and smooth blasting, which can effectively reduce the safety risks of blasting construction. When using blasting method to excavate rock slopes, in order to improve the engineering quality of the excavated slopes, the use of smooth blasting method can effectively avoid or weaken the destructive effect of rock excavation blasting on the surrounding rock, increase the stability of the slope, thereby controlling and reducing disasters such as landslides caused by slope damage, so that the quality of the project can be easily guaranteed.

[0003] Smooth surface blasting of roadbed is the most common excavation method for deep-dig square stone cutting slopes in highway construction. Its characteristics are to arrange blastholes at a certain interval around the excavation limit, and to blast with a controlled resistance line and amount of explosives in the presence of a lateral free surface to form a smooth and flat slope. However, in the actual construction process, since the blastholes are drilled on the roadbed slope, deviations are prone to occur, resulting in changes in the resistance line and affecting the effect of smooth surface blasting. At the same time, deviations will bring about safety hazards such as uncertain directions of flying rocks during blasting.

[0036] The operation principle of the locking structure: the locking structure includes a locking card head 6 and a locking card block 9. Both sides of the locking card head 8 are provided with arc-shaped grooves 801 for easy clamping. The arc-shaped grooves 801 are convenient for life to perform spot checks during installation. A locking card block 9 is fixedly connected to one side of the locking card head 6. A protruding tooth block 901 is provided on the top of the locking card block 9. The locking card block 9 is inserted into the locking card guide groove 501 located on the fixed shaft 5 by passing through the reserved hole on the sealing shaft disk 6, and the protruding tooth block 901 on the top of the locking card block 9 extends out of the locking card guide groove 501 and is clamped on the first inner tooth groove 11, the gasket tooth groove 1801 located on the gasket 18, and the second inner tooth groove 1901. After the slope positioning structure is positioned, the locking block 9 is inserted into the locking guide groove 501. The insertion depth is the width of the second inner tooth rotating sleeve 19. The raised tooth block 901 on the top of the locking block 9 is clamped in the second inner tooth groove 1901 on the inner side of the second inner tooth rotating sleeve 19, so that the slope positioning structure and the vertical angle of the punching machine fixed disk 1 are fixed, that is, the angle C is determined. After the frame is stabilized by adjusting the support leg positioning structure, the locking block 9 is further inserted into the locking guide groove 501 into the first inner tooth groove 11 by pushing the locking head 6 to achieve complete positioning of the structure. This process is simple to operate, and locking and contraction can be easily achieved. The structure is foldable and easy to carry.

[0037] like Figure 1 , 2 As shown in 5, the leg positioning structure also includes a first rotating stiffener 12, a first fixed shaft 13, a second rotating stiffener 14 and a sinking positioning base plate 16. The angle between the first rotating stiffener 12 and the second rotating stiffener 14 is greater than 90 degrees during positioning to prevent the frame from being dragged in the reverse direction and causing instability of the punch frame.

[0038] like Figure 1 ,2 As shown in 5, the first inner tooth groove 11 is evenly arranged on the inner circumferential surface of the first inner tooth rotating sleeve 10, the top angle of the first inner tooth groove 11 is outward from the center of the first inner tooth rotating sleeve 10, and the inner side surface of the first inner tooth rotating sleeve 10 adjacent to the bottom of the first inner tooth groove 11 is arc-shaped, not tooth-shaped, to prevent wear of the fixed shaft 5, one end of the first rotating stiffening rod 12 is fixedly connected to the outer circumferential surface of the first inner tooth rotating sleeve 10, the other end of the first rotating stiffening rod 12 is provided with a first shaft sleeve ear 1201, the first shaft sleeve ear 1201 is installed on the first fixed vertical ears 1401 on both sides of the top of the second rotating stiffening rod 14 through the first fixed rotating shaft 13, the bottom of the second rotating stiffening rod 14 is installed on the second fixed vertical ears 1601 on both sides of the top of the settlement positioning base plate 16 through the second shaft sleeve ear 1402, and a plurality of groups of first limiting nails 17 are evenly installed on the bottom of the settlement positioning base plate 16, and the first limiting nails 17 are tapered downward.

[0039] like Figure 1 , 2 As shown in 5, the slope positioning structure includes a second inner tooth rotating sleeve 19, a positioning stiffening plate 20, an angle pointer 21 and a second limit pin 22.

During positioning, the locking structure preferentially fixes the second inner tooth rotating sleeve 19 including the second inner tooth groove 1901.

[0040] like Figure 5 As shown, a second inner tooth groove 1901 is provided on the inner circumferential surface of the second inner tooth rotating sleeve 19, a positioning stiffening plate 20 is fixedly connected to the outer circumferential surface of the second inner tooth rotating sleeve 19, an angle pointer 21 is installed on one side surface of the positioning stiffening plate 20, a plurality of groups of second limit nails 22 are evenly distributed on the bottom surface of the positioning stiffening plate 20, and a plurality of through holes are also penetrated on the positioning stiffening plate 20. When the fixation is not good, steel nails can be selected to fix the positioning stiffening plate 20 on the slope surface.

[0041] like Figure 2 , 5 As shown, the bottom surface of the positioning stiffening plate 20 is tangent to the circumference of the second inner gear rotating sleeve 19. After the positioning stiffening plate 20 is fixed in parallel on the slope inclined surface, it is equivalent to the slope inclined surface. If the bottom surface of the positioning stiffening plate 20 is not tangent to the circumference of the second inner gear rotating sleeve 19, an angle will be generated, resulting in a reduction in the adjustment angle of the punching machine frame. The second inner gear rotating sleeve 19 and the top surface height are greater than the diameter of the second inner gear rotating sleeve 19, and the tip of the angle pointer 21 points to the center of the circular scale 7.

A locking block 9 is fixedly connected to one side of the locking head 6. A protruding tooth block 901 is provided on the top of the locking block 9. The locking block 9 is inserted into the locking guide groove 501 located on the fixed shaft 5 by passing through the reserved hole on the sealing shaft disk 6, and the protruding tooth block 901 on the top of the locking block 9 extends out of the locking guide groove 501 and is clamped on the first inner tooth groove 11, the gasket tooth groove 1801 located on the gasket 18, and the second inner tooth groove 1901.

[0045] Step 1: Drag the punch frame so that the center of the punch fixing plate (1) is aligned with the punching position;

[0046] Step 2: Fix the positioning stiffening plates (20) of the side slope positioning structure of the punching frame in parallel on the side slope, and after compaction, the second limiting nails (22) at the bottom of the positioning stiffening plates (20) are firmly engaged with the side slope;

[0047] Step 3: By measuring and designing the known slope inclination angle A and smooth blasting inclination angle B in advance, the circular dial reading to be adjusted is: angle C, unplug the locking structure, and according to the formula: smooth blasting inclination angle B = slope inclination angle A + angle C, the difference between the smooth blasting inclination angle B and the slope inclination angle A is the angle C adjusted by the punching frame;

[0048] Step 4: Rotate the puncher fixed plate (1) and read the angle between the vertical line on the puncher fixed plate (1) and the angle indicator (21) on the circumferential scale plate (7), that is, the angle C between the 0 degree mark on the top of the circumferential scale plate (7) and the angle indicator (21);
