Description

Retaining wall structure with improved constructability and construction method thereof The present invention relates to a retaining wall structure with improved constructability and a method of constructing the same, and more specifically, to a retaining wall structure and a method of constructing the same in which the wall end and the bottom plate end are implemented in a shape of a certain dimension to improve construction convenience. In architectural engineering, a retaining wall is a structure used for the stability and protection of land, and it is a structure that maintains land stability by controlling the movement of soil erosion, collapse, and tributaries. These retaining wall structures serve to reinforce the soil, distribute the load on the land, and improve bearing capacity. In addition, retaining wall structures prevent soil compression or erosion, thereby minimizing soil deformation and assisting in the stable construction of structures such as buildings or roads on the land. In addition, retaining wall structures not only prevent environmental pollution by separating the boundary between land and water, but in cities, they can also overcome differences in elevation or topographical constraints to adjust the slope of roads and stabilize the foundation of structures for the construction of infrastructure such as roads or railways. Such retaining wall structures can be designed by referring to standard retaining wall drawings or by assuming a cross-section based on the designer's experience. However, standard retaining wall drawings are developed based on universal conditions and requirements and may not be suitable for all situations. In particular, since various geological conditions, topographical features, and load conditions differ in actual construction sites, problems with stability may arise when designing a retaining wall structure based on generalized standard drawings of retaining walls. In addition, standard drawings of retaining walls are not frequently revised, so there are parts that do not align with recent design trends, making it necessary to conduct additional cross-sectional reviews of the retaining wall structure during actual design. In addition, in the case of a retaining wall structure according to conventional technology, the wall and base plate are formed as a single unit in a certain shape without distinguishing between the body and end of the wall and base plate, respectively, and thus there is a problem in that more material than necessary is required at the end of the wall and the end of the base plate where almost no actual moment occurs.
