Description

A kind of horizontal inclined plate permeable breakwater

technical field

The invention belongs to the technical field of marine engineering, and relates to a novel horizontal oblique plate permeable breakwater.

Background technique

With the development of marine engineering to deep water, the cost of traditional breakwaters has increased sharply, and the construction difficulty has increased. Since the energy of the wave is mainly concentrated in the upper part of the water body, 90%-98% of the wave energy is concentrated in the range of 2-3 times the wave height of the water surface, so we reduce the wave by arranging special structures on the upper layer of the water surface. Therefore, a permeable breakwater structure was created. The new type of permeable breakwater structure has attracted more and more attention due to its advantages such as favorable exchange of internal and external water bodies, low requirements for geological conditions, and low construction cost. The current new breakwater structures mainly include horizontal plate permeable breakwater structures, and the current breakwater structures mainly include double-layer horizontal plate structures and multi-layer horizontal plate structures. The transmittance of the double-layer horizontal plate to the wave is high, mainly to break the wave to reduce the wave, and the reflectivity to the wave is poor, and the wave elimination effect is not good enough. The multi-layer horizontal plate structure is relatively complicated and the cost is high. In addition, the multi-layer baffle permeable breakwater structure has a complex structure, the vertical plate is subjected to a large wave force, the structure is easily damaged, and the construction cost is high and the installation is difficult.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a permeable breakwater with a horizontal inclined plate, which solves the problems of the existing breakwater structure such as poor wave absorbing effect, complex structure and large stress. The beneficial effect of the present invention is that the passing rate of waves can be reduced, and the transmitted wave height can be reduced. By adding sloping boards, the wave force on the vertical boards is reduced, and the structure is more stable.

The invention comprises a first horizontal plate, a second horizontal plate, a first oblique inserting plate and a second oblique inserting plate, the first horizontal plate is located above the second horizontal plate, and the first horizontal plate and the second horizontal plate are supported by the buttresses, The first oblique insert plate is connected to the lower part of the first horizontal plate located on the upper layer, and the second oblique insert plate is connected to the upper part of the second horizontal plate located on the lower layer.

Further, the size of the first horizontal board and the second horizontal board are the same, and the size of the first inclined board and the second diagonal board are the same.

Further, the vertical height of the first oblique inserting board and the second oblique inserting board is half of the distance between the first horizontal board and the second horizontal board.

Detailed ways

The present invention will be described in detail below with reference to specific embodiments.

As shown in FIG. 1 , the novel horizontal oblique plate permeable breakwater of the present invention includes a first horizontal plate 1 , a second horizontal plate 2 , a first oblique plate 3 , a second oblique plate 4 , and a first horizontal plate 1 The same size as the second horizontal board 2, the first inclined board 3 and the second inclined board 4 are the same size, the first horizontal board 1 is located above the second horizontal board 2, and the first horizontal board 1 and the second horizontal board 2 are formed by The support pier 5 is supported, the first oblique insert plate 3 is connected to the lower part of the first horizontal plate 1 located on the upper layer, the second oblique insert plate 4 is connected to the upper part of the second horizontal plate 2 located on the lower layer, the first oblique insert plate 3 and the second The vertical height of the inclined board 4 is half of the distance between the first horizontal board 1 and the second horizontal board 2 .

The permeable breakwater of the present invention is divided into two parts: the upper wave blocking structure and the lower support pier 5 . The upper wave retaining structure is mainly used to cut waves, thereby ensuring a stable water surface in the harbor. The lower buttress 5 mainly supports the upper structure. The wave blocking structure at the upper part of the permeable breakwater structure is fixed, and the support pier 5 at the lower part is permeable. Since the substructure is permeable, the exchange of water bodies inside and outside the port can be carried out, so that the water quality requirements in the port can be maintained. Figure 2 is the flow field distribution diagram of the breakwater of the present invention. The permeable breakwater has the advantages of better wave elimination effect, suitable for deeper waters, lower cost, less influence by geological conditions, and rapid construction.

The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention belong to the present invention. within the scope of the technical solution of the invention.
