Three-pipe-combined wave absorbing unit for emergency floating breakwater

Abstract

A three-pipe-combined wave absorbing unit for an emergency floating breakwater is formed by arranging two permeable wave absorbing pipes and one airbag type wave absorbing pipe in a triangular manner, and is fixed with two triangular grip holders with quick lock catches. Each wave absorbing pipe is of a tubular structure assembled by three arc PVC sheets with radian of 120 degrees, wherein every two PVC sheets are in butt joint through inverted trapezoidal staggered joints, and the three arc PVC sheets with radian of 120 degrees are fixed with two annular grip holders with quick lock catches. Through holes are evenly distributed in the PVC plates of the permeable wave absorbing pipes. A cambiform self-inflation rubber air bag is arranged in the airbag type wave absorbing pipe. The three-pipe-combined wave absorbing unit has the beneficial effects of being fast to assemble, capable of being recycled, low in manufacturing price and good in wave absorbing effect; the permeable wave absorbing pipes can fully utilize water and reflection for absorbing waves, so that the wave absorbing character of the permeable wave absorbing pipes is greatly improved; and the airbag type wave absorbing pipe can adjust the underwater penetration of the breakwater rapidly.

Description

Technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a three-pipe combined wave absorbing unit used for an emergency floating breakwater. Background technique [0002] With the rapid economic development, people have begun to focus on the study of port construction under offshore, deep water and complex foundation conditions. During the construction process, the open sea and deep water conditions are often in an unshielded state, and construction operations in the open sea are often attacked by strong winds, waves and undercurrents. Without effective temporary protection measures, the construction period will be greatly extended. In addition, affected by global climate conditions, sea wave conditions are getting worse, and major maritime disasters occur frequently. How to effectively rescue and stop losses after maritime disasters has put forward higher requirements for rescue and salvage work. It is necessary to ...

AI Technical Summary

Problems solved by technology

[0003] At present, disaster wave conditions are a great threat to port safety and can easily cause serious economic losses; but there is no effective way to reduce its impact. At the same time, with the change of global climate, disaster events occur more frequently
