Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly relates to a construction technology for a gravity retaining wall. Background Art

[0002] The construction of retaining walls is an important link in civil engineering and is widely used in fields such as slope support and road construction. With the acceleration of the urbanization process, the construction space is increasingly limited, and the demand for retaining wall construction in narrow working environments has increased significantly.

[0003] However, traditional retaining wall construction methods face many challenges in narrow spaces. For example, problems such as low construction efficiency, unstable quality, and poor operation flexibility make it difficult to meet the requirements of modern engineering for high-efficiency and high-quality construction.

[0004] The existing technologies have the following deficiencies: Currently, in the industry, to solve the problem of retaining wall construction in narrow spaces, methods such as cast-in-place concrete retaining walls, precast block assembled retaining walls, and construction with small mechanical equipment are mainly used; although cast-in-place concrete retaining walls have the advantages of flexible construction and strong adaptability, they require a long curing time, and it is difficult to perform effective vibration and curing in narrow spaces, resulting in a long construction period and unstable quality. Although precast block assembled retaining walls have a fast construction speed and controllable quality, they are difficult to assemble in narrow spaces, require a large operating space, and have high assembly accuracy requirements, and it is easy to have problems such as loose assembly, affecting the stability and durability of the overall structure. In addition, although construction with small mechanical equipment can relieve the space limitation to a certain extent, due to the limited power of the equipment, the construction efficiency is low, and the operation flexibility in narrow spaces is poor, making it difficult to fully meet the requirements of complex construction environments.

[0005] Therefore, the existing retaining wall construction methods have obvious defects in narrow working spaces, and there is an urgent need for a new construction technology that can significantly improve construction efficiency, ensure stable construction quality, and enhance operation flexibility to meet the actual needs of retaining wall construction in narrow spaces.

[0006] The above information disclosed in the background art section is only used to enhance the understanding of the background of the present disclosure, and thus it may include information that does not constitute the prior art known to those of ordinary skill in the art.
