[0002] Debris flow interception dams can effectively intercept debris flows. They incorporate various design features to improve their impact resistance and drainage performance. Suitable for both sides of mine roads, they can effectively prevent debris flows from impacting and damaging roads, ensuring the safety and smooth flow of mine roads.
[0003] Existing debris flow interception dam structures are used to intercept debris flows. By being installed on both sides of the road, they can prevent sudden debris flows from harming vehicles and pedestrians who have not yet left the road. However, they lack buffering under long-term resistance to debris flows and can be damaged by large rocks, which will affect the interception effect of the dam.
[0004] This utility model designs an interception dam structure on both sides of a mine road to prevent debris flow impact and solve the above problems. Utility Model Content
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A dam structure for preventing debris flow impact on both sides of a mine road includes an earthen base and a dam body. The dam body is fixedly connected to the top of the earthen base. The dam body includes a concrete layer and a dam base. The concrete layer is placed on the upper end of the earthen base, and the dam base is placed on top of the concrete layer. The top of the dam base extends out of the upper surface of the earthen base. An arched dam and a reinforcing support wall located behind the arched dam are respectively installed on the upper end of the dam base. The top of the reinforcing support wall supports the lower end of the top of the arched dam. Two support columns are set on the upper end of the dam base located in front of the arched dam.
[0007] Two support columns are symmetrically distributed on the dam base. Two reinforcing rods are fixedly connected between the two support columns. The two reinforcing rods are located at the top and bottom of the support columns respectively. Multiple support rings are fixedly connected to the reinforcing rods. An interception and buffer metal mesh is installed between the two support columns. The upper and lower ends of the interception and buffer metal mesh are fixedly connected to the support rings on both sides respectively. Multiple buffer mechanisms are fixedly connected to the front face of the arch dam.
[0008] Multiple reinforced barbed column devices with their tops fixedly connected to the concrete layer are installed in the soil base. A buffer step is installed on the front side of the dam base, and a stacking trough is opened on the upper surface of the dam base.
[0009] As a preferred embodiment, the buffer mechanism includes a U-shaped support plate, a rubber support rod, and a rubber buffer bucket. The U-shaped support plate is fixed to the front end face of the arched dam. The U-shaped support plate has a groove with the opening facing forward. The rubber support rod is installed in the groove of the U-shaped support plate, and the rubber buffer bucket is rotatably connected to the rubber support rod.
[0010] As a preferred embodiment, the reinforced barbed post device is a post body, and both ends of the reinforced barbed post device are fixedly connected with a first barbed rivet and a second barbed rivet.
[0011] As a preferred embodiment, multiple through-holes are provided on the dam base and the concrete layer, with the first drainage holes extending vertically, and multiple through-holes are provided on the arch dam, with the second drainage holes extending in the front-to-back direction.

[0013] As a preferred option, a reflective warning plate is fixedly connected to the rear end of the reinforced support wall.
[0014] Compared with existing technologies, the advantages of this utility model are:
[0015] 1. This utility model utilizes an intercepting and buffering metal mesh fixedly connected between multiple support rings at both ends to buffer debris flows while intercepting larger rocks. The arched dam structure can withstand large loads without generating excessive stress concentration in local areas, thereby improving the overall stability and safety of the structure and intercepting debris flows.
[0016] 2. This utility model utilizes multiple reinforcing hook column devices installed at the bottom of the dam body to strengthen the connection between the dam body and the soil base, thereby preventing excessive movement caused by excessive stress on the dam body. The set buffer steps are used to buffer the debris flow by blocking it multiple times. The set accumulation trough is used to fill the accumulation trough after the debris flow occurs, thereby increasing the weight of the dam body and reducing the overall tilting amplitude. The set buffer mechanism is used to reduce the impact of debris flow on the arch dam.
[0017] 3.

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following embodiments or drawings are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0024] A type of intercepting dam structure to prevent debris flow impact on both sides of a mining road, such as... Figures 1 to 4 As shown, it includes a soil base 1 and a dam body 2. The dam body 2 is fixedly connected to the top of the soil base 1. The dam body 2 includes a concrete layer 3 and a dam base 4. The concrete layer 3 is set on the upper end of the soil base 1, and the dam base 4 is set on the top of the concrete layer 3. The top of the dam base 4 extends out of the upper surface of the soil base 1. An arched dam 5 and a reinforcing support wall 6 located behind the arched dam 5 are respectively installed on the upper end of the dam base 4. The top of the reinforcing support wall 6 is supported on the lower end of the top of the arched dam 5. Two support columns 7 located in front of the arched dam 5 are set on the upper end of the dam base 4.
[0025] Two support columns 7 are symmetrically distributed on the dam base 4. Two reinforcing rods 8 are fixedly connected between the two support columns 7. The two reinforcing rods 8 are located at the top and bottom of the support columns 7 respectively. Multiple support rings 9 are fixedly connected to the reinforcing rods 8. An interception buffer metal mesh 10 is installed between the two support columns 7. The upper and lower ends of the interception buffer metal mesh 10 are fixedly connected to the support rings 9 on both sides respectively. Multiple buffer mechanisms are fixedly connected to the front face of the arch dam 5.
[0026] Multiple reinforced barbed column devices 11 with their tops fixedly connected to the concrete layer 3 are installed in the soil base 1. A buffer step 12 is provided on the front side of the dam base 4. An accumulation trough 13 is opened on the upper surface of the dam base 4.
[0027] The intercepting and buffering metal mesh 10 buffers the debris flow while intercepting larger rocks. The arched dam 5, through its arched structure, can withstand large loads without generating excessive stress concentration in localized areas, thus improving the overall stability and safety of the structure. The dam body 2 is fixed to the soil base 1 surface using a concrete layer 3, and the arched dam 5 is reinforced and supported by a reinforcing support wall 6.
[0028] By using multiple reinforcing hook column devices 11, the connection between the dam body 2 and the soil base 1 is strengthened, preventing excessive movement caused by excessive stress on the dam body 2. The buffer steps 12 are used to buffer the debris flow by blocking it multiple times. The set accumulation trough 13 is used to fill the accumulation trough 13 after the debris flow occurs, which strengthens the weight of the dam body 2 and reduces the overall tilting. The set buffer mechanism reduces the impact of the debris flow on the arch dam 5, solving the problem that the existing interception dam structure lacks buffering and is damaged by large rocks, affecting the interception effect of the dam body.
[0029] The buffer mechanism includes a U-shaped support plate 14, a rubber support rod 15, and a rubber buffer bucket 16. The U-shaped support plate 14 is fixed to the front end face of the arch dam 5. The U-shaped support plate 14 has a groove with the opening facing forward. The rubber support rod 15 is installed in the groove of the U-shaped support plate 14. The rubber buffer bucket 16 is rotatably connected to the rubber support rod 15. The rubber buffer bucket 16 reduces the impact of debris flow on the arch dam 5 and enhances the buffering effect of the arch dam 5 through the elasticity and rotation of the rubber.
[0030] The reinforced barbed post device 11 is a post body, and both ends of the reinforced barbed post device 11 are fixedly connected with a first barbed rivet 17 and a second barbed rivet 18. By utilizing the first barbed rivet 17 and the second barbed rivet 18 set on the side walls at both ends of the reinforced barbed post device 11, the gripping ability of the reinforced barbed post device 11 in the soil base 1 is enhanced.
[0031] Multiple through-holes 19 are provided on the dam base 4 and the concrete layer 3. The first drainage holes 19 extend vertically. Multiple through-holes 20 are provided on the arch dam 5. The second drainage holes 20 extend in the front-back direction. By using the multiple corresponding first drainage holes 19 and multiple second drainage holes 20, most of the sewage in the debris flow is discharged into the soil base layer 1, thus preventing sewage from accumulating on the surface of the dam body 2.
[0032] The surface of the dam body 2 is coated with an anti-corrosion epoxy resin coating to enhance the service life of the dam body 2. The surface of the intercepting and buffering metal mesh 10 is coated with a Teflon coating to enhance the service life of the intercepting and buffering metal mesh 10.
[0033] The rear end of the reinforced support wall 6 is fixedly connected to a reflective warning plate 21. The reflective warning plate 21 is used to warn vehicles at night and prevent them from colliding with the dam body 2.
[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
