Description

Technical Field

[0001] The utility model relates to the technical field of flood control mechanisms, in particular to a flood control protection structure during the construction period of a seawall. Background Art

[0002] Seawalls are embankments built along the coast to block tides and waves. Seawalls are important hydraulic structures in sea reclamation projects. As wave-proof structures, seawalls not only withstand the effects of waves, but also block tides. Structurally, seawalls consist of two parts: tide-proof and anti-seepage soil and wave-proof structures. Seawalls are generally not allowed to cross waves, and their top elevation requirements are relatively high. Although the inner slopes of seawalls are mostly earth slopes, they generally do not require face protection because there is no requirement for wave protection.

[0003] During the construction of seawalls, it is necessary to set up corresponding flood prevention organizations. There is currently a seawall slope protection ecological transformation structure with a Chinese patent publication number of CN109868789A, which changes the traditional hard and cold reinforced concrete structure on the outside of the seawall, greatly improving the ecological effect of the seawall; it does not reduce the original seawall's wave-breaking capacity and defense standards, and has no effect on the structural stability of the original seawall; it is easy to construct and has mature technology, and can be applied to the ecological transformation of the hard outer slope structure of ordinary seawalls.

[0004] However, the device is installed directly in contact with the seawall, so its flood control range is relatively limited and its practicality is insufficient. Utility Model Content

[0014] (III) Beneficial effects
