[0013] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementations.

[0014] A mine restoration and anti-soil loss device comprises a modular protective structure 1 and an oblique fixed pin rod 2. The modular protective structure 1 is provided with a plurality of groups, and the plurality of groups of modular protective structures 1 are arranged in an array, and the side ends of two adjacent groups of modular protective structures 1 are connected and fixed by the oblique fixed pin rod 2. The modular protective structure 1 is composed of a ground fixing pile 3, a protective net structure 4, an underground anchor rod 5, and a net fixing bolt 6. The protective net structure 4 is fixed to the top side of the ground fixing pile 3 by the net fixing bolt 6. The underground anchor rod 5 is provided with a plurality of groups, and the upper ends of the plurality of groups of underground anchor rods 5 are fixed in the ground fixing pile 3.

[0015] The protective screen structure 4 is composed of a screen frame 7 and a protective net 8. The protective net 8 is fixed to the side of the screen frame 7. A frame fixing hole 9 is opened on the bottom side of the screen frame 7. The upper end of the screen fixing bolt 6 is passed through and fixed in the frame fixing hole 9, and the lower section of the screen fixing bolt 6 is fixed in the ground fixing pile 3.

[0016] The ground fixing pile 3 is made of reinforced concrete material, and is provided with a straight fixing hole 10 and an oblique through hole 11. The straight fixing hole 10 is provided in multiple groups, and the multiple groups of straight fixing holes 10 are arranged in an array, and the straight fixing holes 10 are connected to the upper side and the lower side of the ground fixing pile 3. The oblique through holes 11 are provided on the side and the top surface of the ground fixing pile 3, and the oblique through holes 11 are connected to the end side and the top side of the ground fixing pile 3. The oblique through holes 11 at both ends of the ground fixing pile 3 are staggered, and the oblique fixing pin rod 2 is inserted into the oblique through holes 11 of two groups of adjacent ground fixing piles. The lower section of the barrier fixing bolt 6 and the upper section of the ground anchor rod 5 are both fixed in the straight fixing hole 10.

[0017] Working principle of the utility model: the use of the structure is simple, and the three-level design has respective functions.

[0018] The function of the underground anchor rod 5 is to form a fixed anchor point on the mine surface, so as to facilitate the subsequent fixing and installation work of the ground fixed pile 3.

[0019] The function of the ground fixing piles 3 is to prevent the soil on the ground from continuing to flow. The soil between the stepped ground fixing piles 3 can be stably stored, and slight rain erosion can also effectively prevent the rain from carrying the soil.

[0020] The function of the protective barrier structure 4 is to reduce the landslide problem after heavy rainfall, and can effectively intercept the falling rocks and mud-rock flows caused by the landslide to continue to trigger a chain reaction.

[0021] In addition, the connection method of two adjacent groups of ground fixing piles 3 is simple. After multiple groups of ground fixing piles 3 are fixed, the connection between the ground fixing piles 3 only needs to use the oblique fixing pins 2 to cross-insert into the oblique through holes 11 at the side ends of the two adjacent groups to complete the fixing and connection of the ground fixing piles 3, so that it can provide overall structural strength and reduce the chain reaction caused by the breakage of the underground anchor rods 5 fixed on the bottom side of the single group of assembled protective structure 1.

[0022] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
