Port breakwater, offshore water-blocking dam and installation method thereof

Abstract

The invention discloses a port breakwater, relates to the technical field of hydraulic construction, and particularly belongs to structural design and installation method of the port breakwater and acoastal reclamation water-blocking dam. The method is characterized in that caissons with pile holes are used as a foundation for installing wave blocking plate assemblies, the wave blocking plate assemblies and wave breaking piles are additionally installed between every two adjacent caissons, and a breakwater is formed by connecting a plurality of caissons and the wave blocking plate assembliesbetween the caissons. A wave breaking pile is installed on a front wave blocking plate and comprises a polyhedral fixed base and a wave breaking column on a wave facing face of the fixed base. The front end inclined plane of the fixed base is the wave facing surface, and the wave breaking column is arranged on the front end inclined plane. The invention provides the port breakwater, the offshore water-blocking dam and the installation method of the port breakwater and the offshore water blocking dam. A large number of sea-filling dike-making complex offshore construction operations in the prior art are changed into a method for manufacturing complete components on land and installing the components on the sea, the components are simple in structure, easy to manufacture and install and short in construction period, the construction cost is greatly reduced, and the influence on the environment of nearby sea areas is small.

Description

technical field [0001] The invention relates to the technical field of hydraulic construction, in particular to a structural design of a harbor breakwater and a land-blocking dam constructed by reclamation of the sea and an installation method thereof. Background technique [0002] In the current port construction projects, apart from building in a naturally formed bay with excellent wind shelter conditions, there is no need to build a breakwater. Recently, a common port is to build a breakwater on the periphery of the planned area with an entry and exit channel for ships to enter and exit. , At the same time, it is also necessary to build a water blocking dam when reclamation of the sea or construction of a tidal dam. [0003] Present breakwaters and water blocking dams are all built with large stones, crushed stones and sand reclamation, and are also installed with integrally prefabricated structural parts of reinforced concrete. On the side of the breakwater facing the s...

AI Technical Summary

Problems solved by technology

Especially in the sea area that deepens suddenly not far from the coastline, the construction cost of the breakwater will increase exponentially, or the port area will have to be reduced, which will affect the operating efficiency and navigation safety of ships in the port.

Even the breakwaters installed with integral prefabricated components still have the above problems

[0006] Third, according to the current port construction method, if there is a cliff-like submarine terrain not far from the coastline, it is impossible to build a breakwater in this sea area, so it is impossible to build a port

[0007] Fourth, there is no doubt that the physical structure of the breakwater has caused changes in the marine biological environment and has had a greater impact on regional marine life
