Description

Technical Field

[0001] The utility model relates to the technical field of roadbed slope, in particular to a composite anti-seepage structure. Background Art

[0002] The roadbed is a structure formed by filling or excavation that directly supports the track, also called the line substructure. The roadbed is connected with bridges and tunnels to form the line. There are two basic forms of roadbed depending on the terrain conditions: embankment and cutting, commonly known as fill and excavation. The roadbed is a geotechnical structure that is often attacked and damaged by changes in natural conditions such as geology, water, rainfall, climate, and earthquakes, and has poor resistance. Therefore, the roadbed should have sufficient strength, stability, and durability.

[0003] Traditional roadbed slope protection structures do not perform well in terms of waterproofing, especially in rainy seasons or humid areas. Water can easily penetrate into the slope through structural gaps or material pores, causing soil softening and reduced strength. Secondly, the stability of these structures is also problematic. Due to the effect of water, the physical and mechanical properties of the slope soil will change, leading to safety hazards such as structural instability and landslides.

[0004] Based on the above, the waterproof effect of the anti-seepage structure of the roadbed slope is particularly insufficient when facing rainy days. This deficiency directly leads to a significant decrease in the stability of the structure. The penetration of rainwater not only makes the soil gradually soften, but also reduces the bearing capacity of the soil, thereby greatly increasing the probability of slope instability and landslide safety risks. The safety hazard not only threatens the normal use of the road, but also poses a serious threat to driving safety. Utility Model Content

[0010] In order to increase greening, as a preferred composite anti-seepage structure of the utility model, the base layer and the planting layer are both soil fillers, and the thickness of the planting layer is 12 cm.

The first concrete frame 8 and the second concrete frame 9 are fixedly installed on the upper surface of the reinforcement layer 15. The first concrete frame 8 and the second concrete frame 9 built by concrete can play a role in reinforcing the roadbed slope.

[0022] As a technical optimization scheme of the utility model, the first concrete frame 8 and the second concrete frame 9 form a drainage channel, which corresponds to the drainage trough 5. The upper surface of the reinforcement layer 15 is paved with a planting layer 6, which corresponds to the second concrete frame 9. Green plants 7 for soil fixation are planted above the planting layer 6.

[0023] In this embodiment: as shown in the figure, the first concrete frame 8 extends roughly along the inclined direction of the inclined surface, the second concrete frame 9 extends alternately with the first concrete frame 8, the first concrete frame 8 and the second concrete frame 9 are designed to be trough-shaped, and the first concrete frame 8 and the second concrete frame 9 are connected through the trough-shaped structure, so that the first concrete frame 8 and the second concrete frame 9 form a drainage channel. At the same time, the first concrete frame 8 and the second concrete frame 9 are arranged in the reinforcement layer 15 to form a planting layer 6. The upper surface of the reinforcement layer 15 is paved with a planting layer 6. The planting layer 6 is on the inner side of the structure enclosed by the first concrete frame 8 and the second concrete frame 9. Through the fixed arrangement of the first concrete frame 8 and the second concrete frame 9 and the reinforcement layer 15, it can speed up the diversion of rainwater and drain it into the drainage ditch 5, reduce the penetration of accumulated water into the roadbed slope, and by planting green plants 7 above the planting layer 6, it can achieve the purpose of increasing the greening of the roadbed slope.

[0024] As a technical optimization solution of the utility model, one end of the drain pipe 10 is sleeved with a filter sleeve 17 for filtering, a plurality of drainage holes 16 are opened on the outer side of one end of the drain pipe 10, and the other end of the drain pipe 10 is threadedly sleeved with a protective head 18; the drain pipe 10 passes through the gravel layer 14 and the reinforcement layer 15, and the filter sleeve 17 is installed at the first filter layer 12 and the second filter layer 13, and the protective head 18 extends into the drainage groove 5.

[0025] In this embodiment: the rainwater is filtered and blocked by impurities through the filter sleeve 17, enters the drain pipe 10 through the drainage hole 16 and is discharged into the drainage groove 5, and the rainwater is drained secondary to reduce water accumulation. The protection head 18 can prevent external garbage from clogging the drain pipe 10, play a protective role on the drain pipe 10, and facilitate better drainage.

[0026] As a technical optimization solution of the utility model, the base layer 2 and the planting layer 6 are both soil fillers, and the thickness of the planting layer 6 is 12 cm.

[0029] In this embodiment: the materials of the first filter layer 12 and the second filter layer 13 are both permeable geotextiles. When the reinforcement layer 15 is cracked or partially damaged and water seepage occurs, the first filter layer 12 and the second filter layer 13 can filter the infiltrated water. When the infiltrated water is close to the waterproof layer 11, it can flow down along the waterproof layer 11. The first filtration of impurities carried by the infiltrated water by the second filter layer 13 can help maintain the water permeability of the first filter layer 12 and prevent the first filter layer 12 from being blocked by impurities such as sludge, thereby reducing the resistance of water flowing down from the first filter layer 12 and facilitating better secondary drainage.

The inclined slope of the reinforcement layer 15 can drain rainwater into the drainage ditch 5 for better drainage.

[0032] Working principle: The base layer 2 is piled and compacted by using large equipment, and the waterproof layer 11, the first filter layer 12, the second filter layer 13, the gravel layer 14 and the reinforcement layer 15 are laid on the inclined surface of the base layer 2 from the inside to the outside in sequence and fixed. On rainy days, rainwater above the road surface 3 will be collected through the downspout 4 into the drainage channel formed by the first concrete frame 8 and the second concrete frame 9, and finally collected into the drainage trough 5. When the reinforcement layer 15 is cracked or partially damaged and water seepage occurs, the first filter layer 12 and the second filter layer 13 can filter the infiltrated water. When the infiltrated water is close to the waterproof layer 11, it can flow down along the waterproof layer 11, and the waterproof layer 11 is used to block and protect the penetration of the base layer 2. The rainwater is filtered again by the filter sleeve 17 and discharged into the drainage trough 5 through the drain pipe 10 for secondary drainage, thereby reducing water accumulation and improving the waterproof performance of the roadbed slope anti-seepage structure.
