Description

Technical Field

[0001] This utility model relates to the field of prefabricated retaining wall technology, and in particular to a prefabricated retaining wall and its revetment. Background Technology

[0002] In the field of civil engineering, retaining wall structures are widely used in slope protection, roadbed support, river management, and other scenarios. Their stability and durability directly affect the safety and service life of the project. Traditional retaining wall construction mostly uses cast-in-place concrete, which, although providing good overall structural integrity, suffers from problems such as long construction periods, significant susceptibility to weather conditions, and difficulty in quality control.

[0003] With the development of prefabrication technology, prefabricated retaining walls have gradually become the preferred solution for engineering construction due to their advantages such as quick construction, controllable quality, and high cost-effectiveness. However, the existing connection methods between adjacent retaining wall modules (such as bolts and welding) are easily affected by external forces, leading to water seepage or displacement at the joints, affecting the overall stability. In addition, the expansion joint design of traditional retaining walls is simple and lacks elastic buffer materials, making it difficult to adapt to deformation caused by foundation settlement or temperature changes, which easily leads to cracks and affects the service quality of prefabricated retaining walls on revetments.
