A curvilinear arch breakwater

Abstract

The invention provides a curved-edge arched wave prevention dam which is mainly formed by a dam body, protecting feet, a seepage prevention curtain, buttresses, piers and a backfilling region I; the protecting feet are distributed along the full length of the coastline and are poured and formed in a foundation stratum; the seepage prevention curtain deep into the impervious bed of the foundation stratum is arranged at the lower ends of the protecting feet; the dam body is located above the protecting feet and is arched, the inner concave surface of the arch shape is a working face of the wave prevention dam, and the outer convex surface of the arch shape is the back of the wave prevention dam; a plurality of stones are backfilled to the back of the dam to form the slope-shaped backfilling region I; a plurality of buttresses are arranged above the backfilling region I; the buttresses are stripe concrete boards obliquely supported at the back of the dam body; a certain distance is formed between adjacent buttresses; a section of clearance is reserved between each buttress and the backfilling region I; a pier is arranged at the rear side of each buttress; and the piers support the bottom ends of the buttresses. The curved-edge arched wave prevention dam is good in wave dissipation effect, can save materials, and is convenient for construction and wide in application.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, in particular to a curved-side arch breakwater. Background technique [0002] Breakwaters are mainly divided into two types: vertical type and slope type according to their cross-sectional forms. [0003] Vertical breakwaters generally consist of walls, superstructures and foundations, mostly riprap foundations. Because the wall is vertical, less material is used, and the space occupied is small. The inner side of the dike can also be used as a dock, which is convenient to use. However, the wall stands vertically in the foundation, which is equivalent to a cantilever structure. The foundation stress is large, so the foundation is required to be solid and have good carrying capacity. Since the wall is vertical, waves with a relatively high flow velocity directly act on the wall, which requires very high quality of the wall, and the wave reflection is large, so the wave dissipation ef...
