Porous floating breakwater

Abstract

The invention discloses a porous floating breakwater. The porous floating breakwater comprises a plurality of breakwater units connected in sequence, wherein each breakwater unit comprises a first buoyancy tank, a second buoyancy tank, connecting rods and two vertical plates, the first buoyancy tank and the second buoyancy tank are rigidly connected through the connecting rods and are connected with an anchoring balancing weight through an anchor chain for anchoring, the two vertical plates are fixedly mounted on the connecting rods, water holes are formed in both vertical plates, and aperture ratio of the water holes in the vertical plates is 9%-11%. The porous floating breakwater is good in wave dissipating effect, small in structure stress, good in safety, simple in structure, convenient to construct and wide in applicable range and has important actual significance in wave resistance of port engineering.

Description

technical field [0001] The invention relates to a porous floating breakwater and belongs to the field of breakwaters. Background technique [0002] The breakwater is an important port and coastal engineering structure, mainly used to defend against the invasion of waves on the port waters, to provide stable and safe berthing conditions and operating waters in the port, and to improve the design conditions of the hydraulic structures in the port. Protection of port hydraulic structures. In addition, on sandy or muddy coasts, breakwaters can also reduce or prevent sediment from entering the port. For frozen ports, breakwaters can also reduce the flow of ice outside the port into the port. The structural types of breakwaters mainly include slope type, vertical type, hybrid type, air-through type and floating type, etc., among which the first three are traditional bottom-sitting type breakwaters. The traditional bottom-seat breakwater can better protect the waters in the port ...

AI Technical Summary

Problems solved by technology

The traditional bottom-seat breakwater can better protect the waters in the port and has a long service life. However, the bottom-seat breakwater has inevitable limitations: with the increase of project water depth and the deterioration of foundation conditions, the project cost increases sharply, and The difficulty of construction is increased; the water circulation in the shelter area is restricted, and sediment deposition and water pollution in the port are prone to occur

[0026] (2) When the wave height is high, the structure of the floating breakwater will be stressed, and the safety of the structure during the service period is difficult to guarantee

This is because floating breakwaters are generally anchored by anchor chains or vertical guide piles. Under the action of waves, the floating breakwater moves with the waves. When large waves act, the floating breakwater will move violently. Limiting the movement of the pontoon will generate a lot of force on the structure. security is difficult to guarantee

[0027] (3) For some complex structure floating breakwaters with better wave dissipation performance, although there are many structural types proposed at home and abroad, the structure of floating breakwaters is subject to large wave forces during large waves, and the safety of the structure itself is difficult to guarantee. decreased sex

For example, for the double pontoon-horizontal slab floating breakwater, although its wave dissipation effect is improved compared with the traditional single pontoon floating breakwater, the force on the anchor chain increases, and the wave force on the lower horizontal plate is also large, and the structural reduced security
