Problems solved by technology
The existing special-shaped face armor blocks cannot be well overlapped with each other, and the integrity is poor. Under the impact of waves, the force is not clear or prone to stress concentration. In addition, the ability to offset waves is poor, and the cost There are many problems such as high, and the degree of construction and wave dissipation effect is not satisfactory, and the protection effect on the breakwater is poor

Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] Such as Figure 1~5 Shown is a preferred embodiment of the present invention.
[0018] A face protection block of a slope type breakwater, including a base body A, the base body A has a base plate 1 and an arched protection body 2, the protection body 2 is arranged on the water-facing surface of the base plate 1, and the base plate 1 and the protection body 2 are poured together Formed, the shape of the protective body 2 is a shield-shaped arch that gradually increases from bottom to top. A cavity 3 with an opening at one end and a lower volume and a larger upper volume is formed between them, and a plurality of drainage holes 21 are opened on the surface of the protective body 2 .
[0019] A drainage hole 21 is provided at the lower end of the protective body, 2 to 3 drainage holes 21 are respectively opened on the left and right sid...

The invention relates to a surface protecting block of a mound breakwater. The surface protecting block comprises a base body (A), and is characterized in that the base body (A) is provided with a base plate (1) and an arching protecting body (2), the protecting body (2) is arranged on the upstream face of the base plate (1), a cavity with an open end is formed between the protecting body (2) and the upstream face of the base plate (1), and a plurality of drainage holes (21) are formed in the surface of the protecting body (2). According to the arching protecting body mainly playing a role in water retaining, wave force can be attenuated better due to the shape of the arching protecting body; besides, since the cavity is formed between the protecting body and the base plate, a water body can fall when waves impact the protecting body, rotational flow is formed in the cavity, and therefore the acting force of water flow is further reduced; in addition, since the drainage holes are punched in the protecting body, on the one hand, water in the cavity can be drained through the drainage holes, one the other hand, convection can be generated between the drained water flow and waves of a next time of wave impact, so that the wave force is reduced, and damage power of the waves to the surface protecting block is reduced.
Description
technical field [0001] The invention belongs to the technical field of port water conservancy engineering, and in particular relates to a face protection block of a slope type breakwater, which is mainly used for the face protection of a slope type breakwater or a slope type revetment. Background technique [0002] The slope type breakwater is a widely used breakwater embankment type, which mainly uses natural stones, concrete blocks and various artificial blocks of special shapes as the protective surface. This requires us to choose the appropriate face protection block according to the specific use environment. The common face protection block styles include I-shaped blocks, four-legged hollow squares, and four-legged cones. The existing special-shaped face armor blocks cannot be well overlapped with each other, and the integrity is poor. Under the impact of waves, the force is not clear or prone to stress concentration. In addition, the ability to offset waves is poor, a...
