Description

Technical Field

[0001] The utility model belongs to the technical field of concrete formwork support, in particular to an integrated retaining wall formwork system. Background Art

[0002] Retaining wall casting construction is a key link in retaining wall construction. Its quality and stability are directly related to the overall performance and service life of the retaining wall.

[0003] When constructing a retaining wall, the foundation is constructed first, then the formwork is installed according to the height of the wall, and finally the concrete is poured.

[0004] Foundation construction involves both foundation reinforcement and wall reinforcement. For foundation reinforcement, a base layer of reinforcement is installed on the foundation cushion. For wall reinforcement, inserts are installed first, followed by vertical and horizontal reinforcement, and finally, tie and support reinforcement. Formwork installation utilizes traditional wooden formwork supports.

[0005] From the above, we can see that in the traditional retaining wall construction process, the construction of wall reinforcement and the installation of formwork are two independent processes, and the construction of wall reinforcement has the problem of numerous processes, time-consuming and labor-intensive; while the installation of formwork also has the problems of low formwork adaptability, time-consuming and labor-intensive formwork support, and low formwork reuse rate.
