Technical Field

[0001] The utility model relates to the technical field of retaining walls, in particular to a pile foundation support beam buttress type retaining wall provided with a supporting structure. Background Art

[0002] A retaining wall, also known as an earth retaining wall, is a structure used to support roadbed fill or hillside soil to prevent the fill or soil from deforming and becoming unstable. A retaining wall is generally composed of a main body such as a wall heel, a wall body, and buttresses. The wall heel serves as the foundation of the entire retaining wall, while the buttresses serve as the supporting mechanism of the retaining wall to maintain the stability of the retaining wall. Some retaining walls will also be equipped with pile foundations due to geological problems to ensure that the retaining wall will not sink or shift.

[0003] However, most of the existing retaining walls are directly constructed on-site, with the wall body and supporting structure as a whole. On-site construction is time-consuming and prone to accidents during the long construction process, such as slope collapse in rainy weather. In addition, once the retaining wall and its supporting structure are deformed or collapsed, it is impossible to make timely repairs, which is inconvenient. Utility Model Content
