Description

Technical Field

[0001] The utility model belongs to the technical field of backfill slope protection engineering and ecological management engineering construction, and relates to a light-weight interlocking assembled ecological retaining wall with preset deformation. Background Art

[0002] In recent years, with the rapid economic growth and continuous progress of science and technology in my country, the country's requirements for highway traffic construction are increasing day by day. While pursuing efficiency, it is also necessary to ensure the quality of the project. As an important part of highway traffic engineering, the quality and stability of retaining walls have a profound impact on the structures and soil built on the walls. In highway construction, due to the very complex actual geological conditions on site, in order to avoid high filling and deep excavation of roadbed, reduce the height of the slope, strengthen the stability of the roadbed, prevent and control roadbed diseases, prevent water erosion from affecting the stability of the embankment, save land, occupy less farmland, and protect important existing buildings, etc., it is often necessary to set up roadbed retaining walls, and they are widely used in highway engineering construction.

[0003] At present, most reinforced concrete projects still use traditional cast-in-place construction technology, which has a long construction period, large manpower investment, many consumables, and heavy pollution. Prefabricated and assembled retaining wall structures started late in my country and developed slowly. Since 2016, the state has successively issued a number of policies on prefabricated and assembled retaining wall structures, vigorously advocating the development of prefabricated and assembled retaining wall structures and building green construction processes. Prefabricated and assembled retaining wall structures, with their reliable quality, high degree of mechanization, and beautiful appearance, will surely become a trend in the development of highway transportation industry structures. Therefore, it is necessary to innovate and explore prefabricated and assembled retaining wall structures.

[0004] Prefabricated retaining walls reduce their own weight to a certain extent, lower the requirements for foundation bearing capacity, and enhance adaptability; most of the components are prefabricated, and the construction time is short, which effectively solves the disadvantage of the long construction period of traditional gravity retaining walls. Compared with traditional construction methods, prefabricated retaining walls can achieve the goals of energy saving, water saving, material saving, time saving, labor saving, and environmental protection, and meet the development requirements of green, circular, and low-carbon in the modern construction industry. The raw materials used in block manufacturing are cheap, the process is simple, the unit cost is low, and the installation cost is low. Even if the area to be installed is large, the cost is easy to bear.

[0005] At the same time, the inconsistent size of the components of the prefabricated retaining wall can easily limit the production equipment, so it is difficult to produce components with larger sizes; although prefabricated buildings have been vigorously promoted by the country, they are currently subject to greater restrictions on the total building height and floor height; the integrity and rigidity of the prefabricated retaining wall are weak, its impact resistance is poor, it is easy to deform or even collapse, and its stability has not been optimized. At the same time, for the slopes of the sand-mudstone mixture filling project, its post-construction deformation is large, and traditional retaining walls are difficult to adapt to the mechanical properties of this type of fill slope, and are prone to instability and damage, leading to accidents. Therefore, a retaining wall that allows deformation needs to be designed for the sand-mudstone mixture filling project. The stress condition of the retaining wall can be adjusted within a certain range as the slope deforms, and a stable state can be reached after a certain deformation stage. Utility Model Content
