Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of revetment device, specifically to a kind of heaped and piled revetment device for preventing collapse. BACKGROUND

[0002] The revetment device is an engineering facility used for reinforcing slope surface, reducing soil erosion and preventing natural disasters such as collapse and debris flow. It protects the safety of roads, buildings and other infrastructure by constructing physical barriers, increasing slope stability and improving water and soil conservation. There are various types of revetment devices, including concrete revetment, ecological revetment and geotextile revetment, and the specific choice is usually determined by topography, soil characteristics, climate conditions and economic considerations.

[0003] The patent with publication number CN220847631U discloses a heaped and piled revetment device for preventing mountain collapse, which includes support blocks. The surface of the support blocks is provided with insertion slots, and the support blocks are also provided with abutting blocks. The surface of the support blocks opposite to the abutting blocks is provided with abutting slots. The inner part of the support blocks is respectively provided with horizontal reinforcing ribs and vertical reinforcing ribs. The support blocks in the utility model can be stacked through the abutting blocks and abutting slots. The stacked support blocks can form columnar structures, and the protective plates can be inserted between two columnar structures to form a protective structure to block falling rocks or debris flow. Meanwhile, the blocks can be stacked to form multiple columnar structures, and the protective plates can be inserted between the multiple columnar structures to form a protective structure. The protective structure can extend along the direction of the road, improving the convenience of installing the revetment device and the flexibility of slope protection.

[0004] The above-mentioned prior art forms columnar structures by stacking multiple support blocks and blocks falling rocks or debris flow by inserting protective plates between two columnar structures. However, this design has certain instability. When falling rocks or debris flow accumulate on one side of the protective plate, the pressure on the bottom of the columnar structure will gradually increase. If the stacking of the support blocks cannot effectively disperse these pressures, the columnar structure may collapse under the action of gravity, causing the revetment device to fail and posing a threat to the surrounding environment and personnel safety. Therefore, in view of the above shortcomings, we propose a heaped and piled revetment device for preventing collapse, aiming to improve the stability of the structure and enhance the overall protection effect.
