[0028] Referring to FIGS. 1, 2 and 3, a slope reinforcing and protecting device for hydraulic engineering is provided. The device includes a connecting base body 10. An upper end of the connecting base body 10 is fixedly connected to a protection assembly 20, a fastening assembly 30 is arranged in the protection assembly 20 for supporting, and a protection net 50 is connected around an outer side of the connecting base body 10. Further, a second column body 34 of the fastening assembly 30 is buried in soil, and a first column body 32 is partially exposed.

[0029] Referring to FIG. 4, the connecting base body 10 is shown. The connecting base body 10 is of a square body, and the center of the connecting base body is provided with an octagonal boss. The center of the boss is provided with a first through hole 14, the boss is at a certain angle, and a drainage groove 11 is provided around the first through hole 14. Trapezoidal notches 12 are provided in both sides of the connecting base body 10, and a plurality of retaining rings 13 are fixedly connected to a side edge of the connecting base body 10.

[0030] Further, water flow outlets of the drainage groove 11 in the surface of the connecting base body 10 are the notches 12 at two sides, and the purpose of arranging the drainage groove 11 is that rainwater can drop to the ground along the drainage groove 11 when rainstorm weather comes, such that excessive rainfall can be prevented from accumulating in the center of the connecting base body 10 to cause soil loosening and collapse. In addition, a service life of the fastening assembly 30 is prolonged to a certain extent.

Embodiment 2

[0031] As shown in FIGS. 2 and 5, the difference between this embodiment and Embodiment 1 is that in the present disclosure, the protection assembly 20 includes a first protection assembly 21. The first protection assembly 21 is composed of two plate bodies, the two plate bodies are fixedly connected, and an included angle between the plate bodies is a right angle. A corner of the first protection assembly 21 is provided with a second through hole 211, and a surface of the plate body is provided with a third through hole 212. A second protection assembly 22 is arranged in the first protection assembly 21, and the second protection assembly 22 is of a square frame body. A fourth through hole 221 with the same diameter as the third through hole 212 is provided in a surface of the second protection assembly 22, and the fourth through hole 221 and the third through hole 212 are coaxial.

[0032] Referring to FIG. 2, Further, the protection assembly 20 is fixedly connected to the connecting base body 10, and a screw rod is arranged in the second through hole 211 in the first protection assembly 21. The screw rod can be firmly clamped in a first base body 33 on a surface of the fastening assembly 30 so as to play a reinforcing role. When a depth of the soil required for protection is relatively low, a considerable portion of the fastening assembly 30 will be exposed to an external environment, which will accelerate the reduction of a service life of the fastening assembly 30. When landslide occurs, the fastening assembly 30 the considerable portion of which is exposed will quite likely to fracture due to uneven stress of bolts inside and outside the soil. The first protection assembly 21 is fixedly connected to the surface of the connecting base body 10, and the first protection assembly 21 is fixedly connected to the second protection assembly 22 through bolts. The first protection assembly 21 and the second protection assembly 22 surround an upper portion of the fastening assembly 30 so as to achieve the purpose of protecting the fastening assembly 30. The screw rod on the first protection assembly 21 can be aligned with a gap between various portions of a first base body 33 so as to control the fastening assembly to accurately ensure the depth by which the fastening assembly 30 is driven into the soil, each bolt can provide a considerable pre-tightening force, and partial soil is prevented from not being compacted and partial soil is prevented from being excessively compacted.

[0033] Referring to FIG. 3, when a fastening base body 35 is completely unfolded, the soil can give the fastening assembly 30 a pushback force. The first protection assembly 21 is fixedly connected to the connecting base body 10, and the counterweight of the first protection assembly 21 is increased, such that the screw rod on the first protection assembly 21 always abuts against the gap between various portions of the first base body 33 in the form of downward pressing, so as to offset the pushback force received by the fastening assembly 30, thereby avoiding the screw rod of the first protection assembly 21 from being offset due to the pushback force given by the first base body 33, and further avoiding loss of the function of controlling the fastening assembly 30.

[0034] Referring to FIG. 6, in the present disclosure, the fastening assembly 30 includes a first column body 32, and a nut 31 is arranged at an upper end of the first column body 32 in a sleeving manner. The first base body 33 is arranged around a surface of the first column body 32, and a second column body 34 is fixedly connected to a lower end of the first column body.

[0035] Further, the first base body 33 has a multi-layer structure and is mainly used for firmly clamping the screw rod of the first protection assembly 21 abutting against the first column body 32. The first base body 33 is arranged on the surface of the first column body 32 in a sleeving manner, and an upper end and a lower end of the first base body are fixedly connected to the nut 31 and an end surface of the second column body 34 respectively. An end portion of the nut 31 is provided with a cross-shaped opening, and a tail portion of the nut is provided with a rotating shaft for urging the supporting rod to move.

[0036] In the present disclosure, a plurality of groove bodies are provided in a side of the second column body 34, supporting rods 36 are arranged in the groove bodies, and bottoms of the supporting rods 36 are fixedly connected to the second column body 34. Fastening base bodies 35 are slidably connected to tops of the supporting rods 36, and bottoms of the fastening base bodies 35 are rotationally connected to the second column body 34. A bolt head 37 is arranged at a lower end of the second column body 34, and a blade-like cutting base body 38 is arranged around a surface of the bolt head 37. The spiral blade-like structure at the top enables the bolt to be driven into the soil more easily and easily, which is conductive to tight abutment between the fastening assembly 30 and the protection assembly 20. The bolt head 37 is of a conical structure, and the cutting base body 38 arranged around the bolt head 37 can stir the surrounding soil, such that the excavated soil forms a space structure with a wide upper portion and a narrow lower portion, and a partial space is reserved for the fastening base body 35 to be unfolded. The fastening base body 35 is unfolded, and the surrounding soil is pushed to move, such that obstruction of the soil to the fastening base body 35 can be reduced, and the conical structure formed by the soil is easier to partially accumulate downwards under a pushing action of the fastening base body 35, which ensures that the bolt head 37 and the fastening base body 35 are completely immersed in the soil to avoid gaps affecting the tightness of the connection.

[0037] When the nut 31 is rotated, the rotating shaft at the tail portion of the nut 31 drives the supporting rod 36 to expand outwards or contract inwards. When the supporting rod 36 is expanded outwards, the space inside the second column body 34 is exposed and can be used for accumulating external soil so as to make the connection tighter. Moreover, an end portion of the supporting rod 36 is connected to the fastening base body 35 in the form of supporting plate sliding, such that the supporting rod 36 can be protected from fracture when the supporting rod 36 expands and contracts in the soil, simultaneously the supporting force received by the fastening base body 35 can be increased, and the fastening base body 35 can be completely unfolded in the soil. When the supporting rod 36 contracts inwards, the rotating shaft at the tail portion of the nut 31 rotates downwards to squeeze soil out of the groove body at a side edge of the second column body 34, so as to avoid the situation that the fastening base body 35 cannot contract smoothly due to insufficient retreat space.

Embodiment 3

[0038] Referring to FIGS. 1, 7 and 8, the difference between this embodiment and Embodiment 1 is that in the present disclosure, an end portion of a protection net 50 is provided with a connecting assembly 40 in a sleeved manner, and the connecting assembly 40 includes a first rotating column body 44. Two sides of the first rotating column body 44 are rotationally connected to a first plate body 41, and a plurality of connecting holes 42 are provided in a surface of the first plate body 41. Limiting grooves 43 are provided between the connecting holes 42, and head portions and tail portions of the limiting grooves 43 are connected to the connecting holes 42. In the present disclosure, the protection nets 50 are connected through the connecting assemblies 40. Surfaces of the connecting holes 42 abut against knots 51, connecting ropes 52 are arranged between the knots 51, and the connecting ropes 52 are arranged in the limiting grooves 43.

[0039] Referring to FIGS. 1 and 8, Further, the rotating column 44 can enable each slope surface protection device to rotate relatively. The slope surface is not a flat plane, and the rotating column 44 can ensure that the connection between the slope surface protection devices will not become loose due to the uneven slope surface, and the situation that the slope surface needing protection cannot be completely covered is avoided. The combination form of rope body crossing and abutting is employed for the protection net 50, and each net opening is of a rhombus, in which crops such as vegetation can be planted for soil reinforcement. The main purpose of the connecting assembly 40 is that after the protection net 50 is arranged, the protection net 50 is usually in a tension state, and when the soil slides due to other factors, the connecting assembly rotates under force, such that the protection net 50 forms a net pocket structure, and sliding soil and stones are caught, so as to avoid the protection net 50 from being broken due to excessive tension.
