[0002] The roadbed is the foundation of the road surface and is a geotechnical structure formed by excavation or filling. The roadbed can provide the necessary conditions for road paving and vehicle operation, and bear the load of the road surface and vehicles or the road surface and traffic, while transmitting and spreading the traffic load deep into the roadbed.

[0003] The Chinese invention patent (invention publication number: CN109958015A name: a frozen soil roadbed protection structure) includes a concrete base, a drainage channel is provided on the front of the concrete base, a rounded gravel slope is provided on the side of the concrete base, a transverse drainage pipe layer is provided at the bottom of the rounded gravel slope, an anti-freeze filling material is provided at the bottom of the transverse drainage pipe layer, a thermal insulation berm is provided at the bottom of the anti-freeze filling material, a slate layer is provided on the side of the thermal insulation berm, a stable foundation filling stone is provided at the bottom of the slate layer, an impermeable geotextile is provided on the upper surface of the concrete base, an asphalt concrete water sealing layer is provided on the upper surface of the impermeable geotextile, a roadbed surface is provided on the upper surface of the asphalt concrete water sealing layer, an anti-skid speed bump is provided on the upper surface of the roadbed, a surface water insulation layer is provided on the left side of the anti-skid speed bump, and a roadbed filling layer is provided at the bottom of the surface water insulation layer.

However, frozen soil will melt in seasons with higher temperatures such as spring and summer. The moisture formed by the melting of frozen soil enters the roadbed, causing the water content in the roadbed to increase. When the water content in the roadbed is too high, it is easy to cause frost heave and mudslides in the roadbed. Summary of the invention

[0010] Preferably, a buffer plate is fixed on the baffle, and a hollow portion is formed between the buffer plate and the baffle, and the hollow portion extends from the middle portion to both ends of the baffle.

[0011] A method for reinforcing a roadbed reinforcement device in a glacial deposit area comprises the following steps: S1: Dig a trench on the side wall of the roadbed, then place the stainless steel water tank, and finally backfill the soil to fix the stainless steel water tank in the trench; S2: According to the actual area of ​​the roadbed sidewall, plan the number and size of the required stainless steel water troughs, and make water guide rods of corresponding length and quantity according to the geological conditions and water content of the roadbed.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1 As shown, a glacial accumulation area roadbed reinforcement device includes a stainless steel water tank 1 embedded in the side wall of the roadbed, the stainless steel water tank 1 is door-shaped and its end is far away from the road surface, and a plurality of water guide rods 2 are also embedded in the roadbed, the water guide rods 2 penetrate the bottom of the stainless steel water tank 1, and the water guide rods 2 are made of porous ceramic material. The stainless steel water tank 1 is covered with a panel 3, and a door frame-shaped grid plate 4 is fixed on the panel 3. The grid plate 4 is used to erect the panel 3 above the stainless steel water tank 1, and the grid plate 4 is fitted with the inner wall of the outer side of the stainless steel water tank 1. The water guide rods 2 can penetrate into the roadbed at multiple points and promote the water in the roadbed to merge with itself, so as to efficiently suck out the water in the roadbed, thereby effectively reducing the water content of the roadbed, greatly reducing the degree of erosion of the roadbed in spring and summer, and improving the deformation resistance and stability of the roadbed. At the same time, the grid plate 4 can also block debris mixed in rainwater to prevent debris from entering the stainless steel water tank 1 and clogging it, thereby ensuring smooth drainage of the stainless steel water tank 1.

[0023] In this embodiment, if Figure 1 and 2As shown, it also includes a mounting plate 5 and a baffle 6. The mounting plate 5 is used to erect the baffle 6 above the panel 3. A wing plate is welded to the side wall of the mounting plate 5 near the bottom. The wing plate is fixed to the side wall of the roadbed through anchor rods 7. The anchor rods 7 located on both sides of the roadbed are staggered into a mesh. The mesh-like cross-arranged anchor rods 7 can achieve a good reinforcement effect, which can effectively improve the stability coefficient and anti-overturning ability of the roadbed, thereby greatly reducing the phenomenon of slope damage and instability. At the same time, the baffle 6 can form a solid and reliable barrier on the side of the roadbed, which can quickly and massively buffer and consume the impact force when objects such as falling rocks appear, thereby reducing the damage of objects such as falling rocks to the road surface.

[0024] In this embodiment, if Figure 1 As shown, the end faces of both ends of the stainless steel water tank 1 are inclined surfaces, and the inclined surfaces face the road surface, so as to conveniently and quickly drain the snow water in the stainless steel water tank 1 to avoid water accumulation.

[0025] In this embodiment, if Figure 4 and 5 As shown, the cross-section of the baffle 6 is wavy, and a waist-shaped hole 8 is opened at the bottom of the wave. Screws are installed in the waist-shaped hole 8, and the screws are used to fix the baffle 6 on the mounting plate 5. Reinforcing ribs are fixed on the baffle 6. The reinforcing ribs are located on the side of the baffle 6 close to the mounting plate 5. The reinforcing ribs include straight ribs 9 and plate ribs 10. The straight ribs 9 are arranged along the extension direction of the baffle 6, and the plate ribs 10 are arranged parallel to the cross-section of the baffle 6. The design of the reinforcing ribs can further improve the rigidity and other structural strength of the guardrail, so that the baffle 6 is more impact-resistant and less prone to bending, deformation and breakage.

[0026] In this embodiment, if Figure 5 As shown, a buffer plate 11 is fixed on the baffle 6, and a hollow portion is formed between the buffer plate 11 and the baffle 6, and the hollow portion extends from the middle portion of the baffle 6 to both ends. The hollow portion can be used to improve the toughness and softness of the baffle 6 to reduce the force of the falling rocks hitting the baffle 6. At this time, the buffer portion of the baffle 6 will make the baffle 6 produce the effect of absorbing vibration and impact force like an elastomer, thereby eliminating the huge energy generated by the impact, so as to minimize the force of damage to the baffle 6 and effectively avoid interception failure caused by the breakage of the baffle 6.

[0027] A method for reinforcing a roadbed reinforcement device in a glacial deposit area comprises the following steps: S1: Dig a trench on the side wall of the roadbed, then place the stainless steel water tank 1, and finally backfill the soil to fix the stainless steel water tank 1 in the trench; S2: According to the actual area of ​​the roadbed sidewall, the number and size of the required stainless steel water troughs 1 are planned, and the water guide rods 2 of corresponding length and quantity are made according to the geological conditions and water content of the roadbed. Then, the water guide rods 2 are sequentially inserted through the stainless steel water troughs 1 and obliquely downward into the roadbed. Finally, the panels 3 are installed to completely cover each stainless steel water trough 1 and splice them into a whole. S3: A channel is opened on the panel 3 that is spliced ​​into a whole to fix the mounting plate 5 on the side wall of the roadbed. The anchor rods 7 on both sides of the roadbed are staggered. The staggered anchor rods 7 form a mesh on the cross section of the highway. Finally, the baffle 6 is fixed above the panel 3 through the mounting plate 5 to buffer the impact of falling rocks on the mountains on both sides of the road.
