Problems solved by technology

[0004] In the prior art, the caisson has problems such as large wave reflection in front of the structure, large force, and easy erosion of the seabed in front of the structure. At the same time, when the wave height is large and the water depth in front of the structure is relatively small, the wave may break and the structure suffers a strong impact. As a result, the wave force on the caisson increases sharply and the wave dissipation effect is not good

Embodiment 1

[0035] Such as figure 1 As shown, different from the existing square caisson, the special-shaped energy-dissipating caisson of this embodiment includes a box body 2, and the side of the box body 2 is suitable for assembling the structure to be assembled. Such as figure 2 As shown, the front side shown is the wave-facing side of the special-shaped energy-dissipating caisson, that is, the front side. The box body 2 includes a left wall, a right wall and a bottom wall. The left and right walls of the box body 2, that is, the two side walls, reserve a through-hole area running through the front and back.

[0036] The upper surface of the bottom wall is below the hollow area, and the lower surface of the fixing block 101 is above the hollow area. In this embodiment, the hollow area is a straight hole, but it may actually have a certain bend. Before actual manufacturing, the hydrological data of the place of use should be referred to, and the overall stability of the structure ...

Embodiment 2

[0055] Such as Figure 8 As shown, multiple embodiments 1 are arranged side by side to form a breakwater, and the compartment 21 is filled with gravel as a counterweight. The breast wall 1 on the upper part is integrally cast on site, and the bottom surface is joined with the top surface of the box body 2 .

Embodiment 3

[0057] The front of the box 2 is a U-shape, including a bottom wall and two caissons. When multiple U-shaped boxes 2 are juxtaposed, the sides of the adjacent caissons are attached, and the fit between the caissons makes the overall stability of the structure better. Wherein the strip-shaped holes of the vertical perforated plate 32 are horizontal, and the strip-shaped holes of the horizontal perforated plate 33 are longitudinal.

Abstract

The invention relates to a special-shaped energy dissipation caisson, which comprises a box body and an energy dissipation device, wherein the box body comprises a permeable area with the front part communicating with the rear part, the energy dissipation device is arranged in the upper half of the permeable area, the side surface of the energy dissipation device is matched with the side surface of the permeable area, a water passage is arranged between the bottom surface of the energy dissipation device and the bottom surface of the permeable area, the front surface of the energy dissipationdevice is arranged behind relative to the front surface of the box body, the energy dissipation device comprises a cavity, the front wall of the cavity is provided with a perpendicular perforated plate which comprises perpendicular strip through holes in the vertical direction, so that the front surface of the energy dissipation device communicates with the cavity., the lower wall of the cavity isprovided with a horizontal perforated plate which comprises horizontal perforated holes in the transverse direction, so that the cavity communicates with the water passage, and the rear wall of the cavity is provided with a wing plate. The design of the special-shaped energy dissipation device of the special-shaped energy dissipation caisson provided by the invention can effectively reduce wave energy, improve the free exchange capacity of sea water and prevent ecological isolation. The velocity of flow at the entrance is reduced to ensure navigation safety. The caisson is light in structure,reduces investment outlay, and is good in structural stress. The modular design makes manufacturing and installation simple and efficient.

Description

technical field [0001] The invention relates to the field of port and coastal engineering, in particular to a special-shaped energy-dissipating caisson. [0002] The invention also provides a breakwater. Background technique [0003] The caisson belongs to the traditional port engineering structure and is widely used in port and coastal engineering such as breakwaters, wharves, and revetments. In recent years, with the rapid development of port and coastal engineering construction, it is more and more common to construct port engineering structures in open waters with big waves, deep water, and fast currents. Therefore, the structural requirements for caissons are also getting higher and higher. [0004] In the prior art, the caisson has problems such as large wave reflection in front of the structure, large force, and easy erosion of the seabed in front of the structure. At the same time, when the wave height is large and the water depth in front of the structure is relati...
