3. The construction quality is easy to guarantee, and various assemblies used in the invention are manufactured in factories and are subjected to quality inspection in the factories, so that the construction quality is easy to guarantee. However, the cast-in-place concrete structure is easy to crack, has a plurality of inconspicuous hidden problems, and also has the problems of uneven vibration, later maintenance and the like during pouring, and has larger artificial influence and natural environment influence.
4. The retaining wall structure is a detachable structure and can be repeatedly used for other projects by only dismantling bolts on the joint plates when the temporary support projects are used.
5. The invention has the advantages that the invention is green and pollution-free, most of the used assemblies are steel structures, and are recyclable metal products, and compared with the recycled metal products, the concrete structure generates a large amount of construction wastes when the service life is prolonged, thereby causing more adverse effects on the environment.
6. The safety and stability are the same as those of other supporting structures, and the safety and stability of the revetment can be maintained during reasonable calculation design.
