[0016] In the description of the utility model, it needs to explain, unless there is explicit provision and limitation, the term "installation", "connection", "connect", "arrangement" should be broad sense understanding, for example, it can be fixed connection, also can be detachable connection, or integrally connected, it can be mechanical connection, also can be electrical connection, it can be direct connection, also can through the intermediate medium indirectly connect, it can be the intercommunication of two elements. For ordinary skilled in the art, the above-mentioned term can be understood according to the specific meaning of the utility model. According to the overall structure of the utility model, its embodiments are described below.

[0017] Referring to Figure 1 And Figure 2 The utility model discloses a kind of precast concrete wave protection wall structures, comprising: front wall and rear wall, the front wall includes the base 11 for contacting ground and the inclined retaining wall 12 for blocking wave, the base 11 and the retaining wall 12 are integrated concrete structure, the rear wall includes the first support plate 21 for abutting the top of the retaining wall 12 and the second support plate 22 for abutting the base 11, the first support plate 21 and the second support plate 22 are integrated concrete structure, from the side of front wall and rear wall, the base 11 and retaining wall 12 form L shape modeling, the first support plate 21 and the second support plate 22 form L shape modeling, the bottom of the second support plate 22 is inserted into the base 11, the upper and lower sides of the retaining wall 12 are fixed by the base 11 and the first support plate 21 respectively, the impact force that the first support plate 21 receives is transmitted to the base 11 by the second support plate 22.

[0018] Different from traditional wave protection wall, this scheme uses assembly structure. On the one hand, the structure gives full play to the advantage that precast concrete structure production efficiency is high;On the other hand, it reduces the amount of internal concrete of wave protection wall, so that the weight of wave protection wall in unit length is greatly reduced. Based on this, the wave protection wall in the scheme of the application has the characteristics of high transportation efficiency and low cost, and the L-shaped structure facilitates the compact placement of a plurality of front wall and rear wall, not only reduces the dependence on heavy crane, but also reduces construction cost, and also shortens construction period. It should be noted that when splicing two sections of wave protection wall, gap between two sections of wave protection wall is filled with waterstop rubber pad.

[0019] As an improvement of the above scheme, the retaining wall 12 is arc-shaped, and the bending direction of the retaining wall 12 faces the second support plate 22. By adopting the above scheme, it is helpful for the retaining wall 12 to absorb the impact force of wave.

[0020] As an improvement to the above solution, the front of the retaining wall 12, which is used to resist waves, is provided with several protrusions or several recesses. The protrusions and recesses serve to break waves and dissipate energy.

[0021] In the first option, such as Figure 1 As shown, the first support plate 21 has a pair of downwardly protruding ribs at the position abutting the top of the retaining wall 12, and the first support plate 21 clamps the front and rear sides of the retaining wall 12 by the ribs. In the second embodiment, as... Figure 2 As shown, the first support plate 21 has a downwardly protruding rib at the position where it abuts the rear side of the retaining wall 12. A screw is pre-embedded in the top of the retaining wall 12. The screw passes through the top of the first support plate 21 and is tightened by a nut.

[0022] Since the upper and lower sides of the retaining wall 12 are locked by the base 11 and the first support plate 21 respectively, the retaining wall 12 can withstand a large impact force, and the thickness of the retaining wall 12 can be reduced to 20cm, further reducing the weight.

[0023] In other designs, the upper surface of the base 11 is inclined, with the side closer to the retaining wall 12 being lower than the side farther from it. The bottom of the retaining wall 12 has drainage holes 30. In this design, a small amount of waves may enter the interior of the wave-breaking wall, but due to the inclination of the upper surface of the base 11, the water will drain away quickly. In actual construction, it is not necessary to provide drainage holes 30 for every section of the wave-breaking wall.

[0024] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. The scope of the present invention is intended to be defined by the claims and their equivalents.
