Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-3 As shown, a gravity retaining wall heightening structure comprises an old retaining wall 1 and dry-hanging granite 3 arranged at the left side thereof; a fifty-centimeter-level crushed stone layer 9 and a fifty-centimeter steel bar foundation are arranged behind the old retaining wall 1, on which a C30 concrete wall body 4 is cast-in-place and the integrity is enhanced by arranging embedded steel bars 2 between the old and new retaining walls 1. The utility model is improved to increase the retaining wall top elevation, enhance the water retaining and flood prevention effects, and at the same time increase the overall stability and safety of the retaining wall.

[0023] like Figure 2 and Figure 3 As shown, a plug-in board layer 10 is arranged at the middle position of the C30 concrete wall 4, and an upper foam layer 11 is arranged at the upper end position of the plug-in board layer 10. The upper foam layer 11 will float due to the buoyancy of water. The floating plug-in board layer 10 and the upper foam layer 11 can further increase the height of the retaining wall, thereby further improving the flood prevention capacity of the retaining wall.
