Description

Technical Field

[0001] The invention belongs to the technical field of retaining wall construction, and in particular relates to a construction method of a square and circular window-type retaining wall. Background Art

[0002] Window-type retaining walls typically use concrete, rubble concrete, mortared slab stone, pebbles (gravels), and other materials to create a lattice framework. Plants or other auxiliary protective measures are used within the lattice to effectively prevent gullies from forming on the slopes due to water erosion. During the construction of window-type retaining walls, manually assembled formwork is typically used to reserve the window openings, and then the retaining wall frame is cast. When constructing the frame formwork on steeper slopes, not only does it require enhanced formwork fixation to prevent it from slipping, but the frequent installation and removal is also tedious, requiring significant labor, material resources, and time. The formwork can also deform during this process, affecting the dimensional accuracy of the window openings.

[0003] In view of this, in order to improve the construction quality and efficiency of square and round window-type retaining walls, it is urgent to invent a square and round window-type retaining wall construction method that can reduce the difficulty of installing and positioning the window-type reserved template, reduce the template installation and disassembly time, and realize integrated and standardized operations.
