Embodiment

[0017] A hollow-type wave-dissipating pipe for emergency floating breakwaters, such as figure 1 As shown, three 120° arc-shaped PVC plates 1 are assembled into a cylindrical structure, and the two PVC plates are connected by a staggered joint, and the staggered joint is an inverted trapezoid, such as figure 2 As shown, through holes 2 are evenly distributed on the PVC board, and three 120° arc-shaped PVC boards 1 are fixed by two ring fastening frames 4 with quick locks 3 .

[0018] In this embodiment, three pieces of 120° arc-shaped PVC plates are assembled to form a hollow-type wave-dissipating pipe with an outer diameter of 3m, a length of 30m, and a thickness of 150mm in the PVC plate; the diameter of the through hole on the PVC plate is 150mm. The spacing is 628mm; the ring fastening frame is formed by connecting two semicircular steel strips, the thickness of the steel strip is 20mm, and the width of the steel strip is 150mm.

Abstract

A permeable type wave dissipation pipe used for an emergency type floating breakwater is of a cylindrical structure formed by assembling three 120-degree arc PVC sheets. Every two PVC sheets are in butt joint in a staggered-joint mode. Each staggered joint is in an inverse trapezoid shape. Through holes are evenly distributed in the PVC sheets. The three 120-degree arc PVC sheets are fixed through two annular fastening frames with rapid buckles. The permeable type wave dissipation pipe has the advantages that the permeable type wave dissipation pipe is simple in structure and easy to implement; the permeable type wave dissipation pipe reduces the flow speed of water flow through the through-hole structure, the flowing directions of water flow in three dimensions are changed, the flowing conditions of incoming flow and incoming waves are affected, and therefore spreading of waves and ocean currents is damaged, and the effect of wave and current dissipation is achieved; the permeable type wave dissipation pipe is good in wave dissipation performance, quick to assemble, capable of being repeatedly used, low in manufacturing cost and the like, and meets the requirements for offshore emergent salvage and port engineering emergent wave resistance.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a hollow-type wave-dissipating pipe used for emergency floating breakwaters. Background technique [0002] With the rapid development of the economy, people have begun to focus on the research of port construction under offshore, deep water and complex foundation conditions. During the construction process, the open sea and deep water are often in an unprotected state. When construction operations are carried out in the open sea, they are often attacked by strong winds, waves and undercurrents. Without effective temporary protection measures, the construction period of the project will be greatly extended. In addition, affected by global climate conditions, sea wave conditions are getting worse and worse, and major maritime disasters occur frequently. How to carry out effective rescue and stop losses after maritime disasters occur, which puts forward higher ...
