Multifunctional seawall system

Abstract

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.

Description

technical field [0001] The invention relates to hydraulic engineering / water transportation engineering, in particular to a multifunctional seawall system. Background technique [0002] The seawall is an important hydraulic structure to resist the attack of waves and protect the buildings behind the embankment. In the traditional technology, the seawall usually only considers the protection function of the rear land area, the plane layout is simple, the structure function is single, and the ecological effect is poor. If the foreshore of a single-structure seawall is not well protected, it will be easily eroded and washed down by the long-term erosion of waves and currents, eventually causing the foot of the embankment to be washed out, and even cause the seawall to become unstable and damaged. Moreover, the foreshore of the seawall is basically a smooth beach, lacking in ecology. [0003] In order to solve the above problems, we have made a series of improvements. Content...

In the traditional technology, the seawall usually only considers the protection function of the rear land area, the plane layout is simple, the structure function is single, and the ecological effect is poor

If the foreshore of a single-structure seawall is not well protected, it will be easily eroded and washed down by the long-term erosion of waves and currents, eventually causing the foot of the embankment to be emptied, and even cause the seawall to become unstable and damaged

Moreover, the foreshore of the seawall is basically a smooth beach, which lacks ecological features.
