Description

Technical Field

[0001] The utility model relates to the technical field of breakwater structures in marine engineering, in particular to a simple passage structure located on the top of the breakwater. Background Art

[0002] In recent years, my country's nuclear power plants (thermal power plants) have reported a number of operational incidents caused by marine organisms or marine debris blocking the water intake system, and the number of related abnormal reports has been increasing. Doing a good job in protecting the front end of the water intake channel is the top priority of cold source protection.

[0003] In order to meet the needs of operation and maintenance personnel for inspection and salvage of waste, a pedestrian passage needs to be set up on the top of the breakwater of the open water intake channel.

[0004] At present, most of the open channel breakwaters (diversion dikes) of power plants in service adopt the structure of riprap slope embankment + artificial face protection blocks. The artificial face protection blocks usually adopt a twisted king-shaped block structure, and people cannot pass on the upper part of the face protection blocks. Therefore, it is urgent to design a simple passage structure located on the top of the breakwater to solve the above problems. Utility Model Content

[0005] In view of the above existing technical problems, the utility model provides a simple passage structure located on the top of the breakwater, characterized in that it includes a passage structure and a railing installed on the top of the breakwater, the passage structure is composed of a horizontal part and a bent part, the horizontal part and the bent part are connected as an integral structure, the horizontal part and the bent part are both provided with drainage holes for effectively reducing the buoyancy of waves, and railings are fixedly installed on both sides of the top surface of the horizontal part through embedded parts,

[0006] The embedded parts are composed of steel plates and embedded columns. The embedded columns are fixedly installed at the four corners of the steel plates.

[0007] The installation position of the passage structure is located at the back-wave side of the slope protection embankment.

[0008] Specifically, the passage structure is a plain concrete structure, and the construction and installation method of the passage structure is any one of the following two methods: on-site casting construction and prefabricated installation construction.

[0009] Specifically, the passage structure is a part of the face protection block structure arranged on the top of the breakwater, and the thickness of the horizontal part and the bent part is consistent with the thickness of the face protection block, which is convenient for on-site construction.

[0010] Beneficial effects of the utility model:

[0011] The passage structure designed by the utility model can be designed in combination with the size of the original face blocks of the breakwater, and its structural size can be adjusted according to the use requirements to meet the needs of small and simple equipment passage or installation;

[0012] The passage structure designed by the utility model is arranged and installed on the back side of the breakwater crest as a part of the face block structure, which not only meets the stability requirement of the breakwater face, but also meets the requirement of personnel passage. The passage structure can be installed by on-site casting construction or prefabricated installation construction, and the installation and construction of the structure is also relatively convenient.

DETAILED DESCRIPTION

[0019] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0021] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Example 1

[0023] As shown in the figure, the passage structure 1 is installed on the top of the breakwater and is located at the inner side of the channel (back wave side) of the breakwater axis 100. The passage structure 1 can be used as a part of the protective block structure at the top of the breakwater. The thickness of the passage structure 1 is consistent with the thickness of the protective block 101, which is convenient for on-site construction. The passage structure is a plain concrete structure and can be cast on-site or prefabricated and installed.

[0024] The passage structure 1 is composed of a horizontal portion 11 and a bent portion 12, which are connected as an integral structure. The horizontal portion 11 and the bent portion 12 are both provided with drainage holes 13, which can effectively reduce the buoyancy of waves and ensure the safety and stability of the structure under the action of offshore waves. The railings 2 are fixedly installed on both sides of the top surface of the horizontal portion 11 of the passage structure 1 through embedded parts 21.

[0025] like Figure 5 and 6 The railing 2 is provided with an embedded part 21, which consists of a steel plate 211 and an embedded column 212. The embedded columns 212 are fixedly installed at the four corners of the steel plate 211.

[0026] Example 2

[0027] When the utility model is installed on the slope breakwater, for the newly built slope breakwater, the newly built breakwater needs to first install the protective block 101 adjacent to the passage structure 1, and then adopt the method of on-site casting or prefabrication installation to construct the passage structure 1. The structural size of the passage structure 1 matches the structure of the protective block 101, and is provided with a drainage hole 13, which can effectively reduce the buoyancy of waves and ensure the safety and stability of the structure under the action of offshore waves. The railing 2 is installed on the top of the passage structure 1 through the embedded part 21, and a simple track installation can be performed in combination with the use requirements.

[0028] When renovating an existing breakwater, it is necessary to remove the face blocks 101 used to install the passage structure and install the passage structure 1. The structural dimensions of the passage structure 1 match the face block 101 as part of the entire face block structure on the breakwater.

[0029] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The various components mentioned in the utility model are common technologies in the existing field. The technicians in this industry should understand that the utility model is not limited by the above embodiments.
