The invention relates to a multifunctional
seawall system. The multifunctional
seawall system comprises a main
seawall, a longitudinal dam, a cellular dam and a beach protection and
siltation promotion area, the longitudinal dam is parallelly arranged on the
wave resistance side of the main seawall, the cellular dam is perpendicularly connected with the main seawall and the middle of the longitudinal dam, and the beach protection and
siltation promotion area is arranged among the main seawall, the longitudinal dam and the cellular dam, wherein the beach protection and
siltation promotion area comprises an
intertidal zone, water plants and bentonic
organism. Compared with a traditional technology, according to the multifunctional seawall
system, the longitudinal dam and the cellular dam are additionally arranged on the
wave resistance side of the main seawall,
waves can be effectively weakened, the wave load acting on the main seawall structure is reduced, the
sediment carrying capacity of a
water body is weakened,
sediment backflow is blocked, depositing of
sediment on the foreshore of the main seawall is facilitated, the main seawall foundation is protected from being eroded and scoured, the function of beach protection and siltation promotion is achieved, the anti-sliding stability of the main seawall is enhanced through sediment deposited in front of the dam, the stability safety factor is increased, a growth
habitat is provided for the water plants, the bentonic
organism and birds, the
peripheral ecological environment is improved, the ecological benefits are improved, and growth of large water plants plays a role of certain wave dissipation.
