And the sand and stone material part at the lowest layer of the inner backfilling part is backfilled by 1-1000 kg of lump stones or medium grit commonly used for hydraulic structure dikes, and the specific weight and specification of the lump stones or the medium grit are preferably selected according to the sand and stone material of the local site. And the two stones and the broken stone cushion layer of the backfilling part are laid on the upper part of the sand stone material layer and used for leveling gaps among the stones. The C30 concrete wharf surface layer of the inner side backfill part is laid on the upper parts of the two stone and broken stone cushion layers, and the specific strength grade is determined by combining the load above the wharf. The size is not limited to the above, and the material is not limited to the above.
The gabion mesh is internally provided with filling stones 4 and poured with underwater self-protecting concrete 5.
The gabion mesh main body frame of the gabion mesh for automatically protecting the concrete bond underwater is formed by vertically stacking a plurality of gabion mesh, and the vertical structure of the outer edge of the temporary wharf is guaranteed. The lowest gabion mesh needs to be buried for a certain depth treatment in consideration of the geological conditions of the local seabed. The outer frame of the gabion mesh is made of PVC iron wires, and the outer layer of the gabion mesh is subjected to anticorrosion treatment so as to enhance the resistance to corrosion of chloride ions in seawater and keep a stable state under the seawater condition. The interior of the gabion mesh main body frame structure is filled with the rock blocks, and the specific weight and specification of the rock blocks are preferably selected according to the rock materials on the local site. After the stone blocks are filled, under the action of external force load, no sliding is generated between the gabions.
