In addition, the connection stability is poor due to the placement alone, which poses certain safety hazards.

[0026] To do this, see Figure 1-4 The utility model provides a prefabricated concrete slope protection component and a slope protection structure, the slope protection component comprises an upper slope protection component 1 and a lower slope protection component 2, the cross section of the upper slope protection component 1 and the lower slope protection component 2 after being matched can form a hexagonal structure, a semicircular through groove is opened on the side wall opposite to the upper slope protection component 1 and the lower slope protection component 2, a semicircular support plate 3 is fixedly connected in the two semicircular through grooves, the bottom ends of the two semicircular support plates 3 are flush with the bottom ends of the upper slope protection component 1 and the lower slope protection component 2, a plurality of circular through holes 31 are opened on the two semicircular support plates 3, and a semicircular through hole 32 is respectively opened at the center of the two semicircular support plates 3 after being matched, and the two semicircular through holes 32 can form a circular through hole 31, a combined through hole of the same size, a locking structure is connected between the upper slope protection member 1 and the lower slope protection member 2, a latch a11 with an isosceles trapezoidal structure in vertical section is fixedly connected to the left side wall of the upper slope protection member 1, a latch c21 with an isosceles trapezoidal structure in vertical section is fixedly connected to the left side wall of the lower slope protection member 2, a pin groove c12 matching with the latch c21 is provided on the right side wall of the upper slope protection member 1, a pin groove a22 matching with the latch a11 is provided on the right side wall of the lower slope protection member 2, a synchronous locking anti-slip structure 4 is installed in the semicircular through groove of the upper slope protection member 1, and the synchronous locking anti-slip structure 4 is connected with the latch a11, the latch c21, the pin groove c12 and the pin groove a22;

[0030] The arrangement of the engaging structure enables the upper slope protection member 1 and the lower slope protection member 2 to be initially engaged with each other.

[0031] Further as Figure 1-4 As shown, it is worth specifically explaining that in order to prevent multiple groups of slope protection components from sliding after being laid, a synchronous locking anti-slip structure 4 is provided, including an inverted L-shaped guide rod 47 fixed to the middle part of the inner wall of the upper slope protection member 1, and a transmission rod 45 is slidably sleeved on the outer side of the inverted L-shaped guide rod 47, and a transmission channel 46 is provided on the transmission rod 45.
