Ship intercepting system and application thereof

Abstract

The invention discloses a ship intercepting system and application thereof.The ship intercepting system comprises a blocking net, a plurality of independent guide columns fixed to the underwater ground and energy consumption barrels arranged outside the independent guide columns in a sleeving mode, and the blocking net is fixed between the energy consumption barrels; the device can be applied to interception of non-navigable holes in large water areas or collision prevention of ship side collision of existing bridges, and has the advantages of being environmentally friendly in energy dissipation form, high in energy dissipation capacity, low in construction and maintenance cost and capable of resisting large storm waves and ship collision.

Description

technical field [0001] The invention relates to the technical field of bridge anti-collision engineering, in particular to a ship interception system and its application. Background technique [0002] Bridges in navigable waters are at risk of being hit by ships, and once a ship hits, the ship and bridge will be damaged in light, and the ship will sink or the bridge will collapse, which directly endangers people's lives. Even the traffic network is paralyzed, so the consequences of a ship-bridge collision are often severe. [0003] The technical background of the present invention is mainly based on the following two points: [0004] (1) Protection of bridge piers at non-navigation holes in large waters [0005] Bridges in navigable waters can generally be divided into navigable holes and non-navigable holes. It is generally believed that the piers at the navigation holes are at high risk of being hit, and anti-collision design or anti-collision devices are mostly conside...

AI Technical Summary

Problems solved by technology

When this type of interception system works for a long time, there are also the following problems: the interception system relies on the anchor block to fix the position, and the normal operation of the anchor block is very dependent on the underwater landform and other conditions. Because the anchor block is located at the bottom of the water, the anchor block cannot be observed in daily maintenance. working conditions; when the anchor block is misaligned, it is difficult to check and reset

[0008] As mentioned above, this type of floating body-block-anchor interception system mainly relies on the sliding of the anchor block on the bottom of the water to dissipate energy, but this energy consumption method is too dependent on the bottom landform conditions; If it is in the form of energy, its reliability is insufficient under the action of wind and waves in the sea area; because the main component of the fixed block system is the anchor block, the working state of the anchor block cannot be controlled artificially, and the block often falls off and becomes entangled under the action of typhoon and other wind waves. etc., floating body displacement, tower collapse and overturning, etc., so the long-term normal operation of the interception system cannot be guaranteed, and the maintenance cost is too high and the maintenance technology is difficult

[0009] (2) The problem of lateral collision avoidance of weak piers at the navigation holes of existing bridges

This type of bridge pier has a slender structure, and its own anti-collision ability is extremely poor. Attached and self-floating anti-collision devices usually cannot meet the actual anti-collision requirements, and artificial islands and other forms in this type of watershed are obviously unrealistic. The anti-collision structure can effectively resist the forward impact of the ship through reasonable design, but according to the above accidents, it can be found that in these serious ship collision accidents, there are ships hitting the pier sideways, causing the pier to displace along the direction of the bridge and then Serious Accidents Leading to Falling Beams

Although such accidents occur frequently, the existing anti-collision facilities are difficult to effectively deal with these ship collision accidents

[0012] In summary, bridges in wide waters (especially cross-sea bridges) need a brand-new bridge that adapts to complex wind and wave environments and can work reliably for a long time in harsh climates; in another case, existing bridges There are a large number of double-column weak piers in the bridge, and there is a risk of damage caused by prominent frontal and side collisions. The existing anti-collision devices cannot effectively solve the protection problem, and an economical and reasonable new protection method and measure are needed
