Mooring buffering ship collision preventive system

Abstract

A mooring buffering ship collision preventive system comprises a floater, main anchors, main ropes, damping units, a buffering pad, auxiliary anchors, auxiliary ropes and the like. The floater is moored through the main anchors, the main ropes, the auxiliary anchors and the auxiliary ropes; at least two damping units on the floater are disposed at intervals; each damping unit is composed of a damping chain, an energy-dissipating rope and the like. The mooring buffering ship collision preventive system has the advantages that energy can be dissipated by continuously elongating and breaking the energy-dissipating ropes, the moving direction of a ship can be changed through the floater which is in oblique connection with the axis of a bridge, energy can also be dissipated by elastic plastic deformation of a collision preventive pad arranged on the floater and of a floater structure, mutual action between the ship and collision preventive equipment can be greatly reduced, impact that a pier possibly bears is greatly reduced, and the safety of the pier and of the ship can be protected.

Description

Technical field [0001] The invention relates to a bridge anti-ship collision system, in particular to a separate moored floating anti-ship collision system for protecting bridge piers. Background technique [0002] There are mainly two types of well-known bridge pier anti-ship collision facilities. [0003] One type is the attached anti-collision facilities installed on the bridge piers. There are relatively more engineering applications. The structural deformation of the anti-collision facilities is mainly used to consume the kinetic energy of the ship and prolong the impact time. Usually, it can reduce the impact force of the ship by about 30%, but The pier itself has high requirements for collision resistance, and its construction and installation costs are high. It is difficult and expensive to repair after being hit by a ship, which is not conducive to protecting the ship out of control. [0004] The other type of separate anti-collision facilities set at a certain distance fro...

AI Technical Summary

Problems solved by technology

For fixed anti-collision facilities such as independent anti-collision piers and artificial islands, not only the construction and installation costs are relatively high, but it is also not conducive to protecting out-of-control ships.

For mooring buoys, gravity anchors can be used to move the anchor or the deformation of the anchor cable consumes energy, which is beneficial to protect out-of-control ships, but the gravity anchor may be trapped in the mud and cannot move the anchor, and the bearing capacity of the anchor cable exposed to water and sunlight will drop rapidly , it is difficult to continue to function
