Description

Ship interception system and application thereof

Technical Field

The invention relates to the technical field of bridge anti-collision engineering, in particular to a ship interception system and application thereof.

Background

The bridge in the water area of navigation has the risk of being struck by boats and ships, and once boats and ships strike, light then ship, bridge damage, heavy ship sinks, the bridge collapses, directly endangers people's life safety, and the interruption of bridge usually can make whole traffic line or even traffic network paralysis, therefore the result that the ship bridge collision produced is often very serious.

The technical background of the invention is mainly based on the following two points:

protection problem of pier at non-navigation hole of large water area

The bridges in the navigation water area can be generally divided into navigation holes and non-navigation holes. Generally, the pier at the navigation hole is considered to have a large collision risk, and the anti-collision design is considered or an anti-collision device is arranged in the design. However, in a bridge in a large water area, the number of navigation holes is generally small, the number of non-navigation hole piers with large span length and single thin structural design is a weak link for collision resistance, the navigation clearance at the non-navigation holes is low, the piers are relatively weak in design due to factors such as small span and the like, and once ship collision occurs, collapse of a main beam and failure of the piers are easily caused, so that serious accidents are caused.

According to the specification of 'design standard for collision resistance of highway bridges' JTG/T3360-02-2020, the bridge collision resistance region comprises a main navigation hole, an auxiliary navigation hole and a non-navigation hole which can be reached by a ship under the designed highest navigation water level. Therefore, collision avoidance needs to be considered when the pier which is possibly collided exists at the non-navigation hole. If the number of piers at the non-navigation hole is not large and the navigation clearance is met, the anti-collision design can be carried out by referring to the navigation hole if the anti-collision requirement can be met by one-by-one defense of the single piers. However, in a wide water area, such as a cross-sea bridge and the like, the number of non-navigable pore piers is extremely large, if the concept of defense arrangement of a navigable pore to a single pier is still referred, the large manufacturing cost and the high construction difficulty are unrealistic, and the navigable clearance of the non-navigable pores cannot meet the requirement, so that the design concept of anti-collision and anti-collision of the traditional single pier cannot be applied to the non-navigable pores.

Based on the consideration, the collision avoidance of the bridge piers at the non-navigable holes generally adopts a ship interception system, but the number of the interception systems aiming at the non-navigable holes at home and abroad is relatively small, the existing interception system mainly comprises a floating body-blocking net-anchor block type interception system, and the interception system mainly comprises a floating body, a blocking net and an anchor block. The floating body part mainly comprises structures such as a light floating cylinder and the like and has the function of ensuring that structures such as a blocking net and the like float on the water surface; the blocking system part is connected with the anchor block and the floating body and mainly plays a role in blocking the ship and transferring the kinetic energy dissipation of the ship to the anchor block; the anchor block mainly has the effect that after the ship is intercepted, the ship drives the blocking net to move, and then the anchor block is dragged to slide on the water bottom for energy consumption, so that the main energy consumption effect is achieved. Based on the floating body-blocking net-anchor block type interception system, some improved interception systems have been developed, such as: the floating body is arranged in a form of overhead type, automatic falling type and the like, or the cable of the blocking net is arranged in a form of partial breaking energy consumption and the like, but the structural form and the energy consumption form of the main body are not substantially changed, the blocking systems belong to the same class in nature and can be applied to partial water areas. Once such damage occurs, maintenance costs are extremely high. When the interception system works for a long time, the following problems also exist: the interception system depends on the fixed position of the anchor block, the normal work of the anchor block depends on the conditions of underwater landform and the like, and the working condition of the anchor block cannot be observed by daily maintenance because the anchor block is positioned at the water bottom; when the anchor block is misaligned, it is difficult to check and reset.

As mentioned above, this kind of floating body-block-anchor block type interception system mainly relies on the sliding of anchor blocks under water for energy consumption, but this energy consumption mode is too dependent on the topography condition of water bottom; the auxiliary energy consumption mode is controlled by using the fracture failure of part of anchor chains, so that the reliability of the anchor chains is insufficient under the action of wind waves in the sea area; the main components of the fixed blocking net and other systems are anchor blocks, the working state of the anchor blocks cannot be manually controlled, and the problems of falling, winding and the like of the blocking net, displacement of a floating body, collapse and overturning of a tower and the like often occur under the action of wind waves such as typhoons and the like, so that the long-term normal operation of the blocking system cannot be ensured, the maintenance cost is overhigh, and the maintenance technical difficulty is high.

(II) lateral collision avoidance problem of weak bridge pier at existing bridge navigation hole

Common anticollision facilities of pier at navigation hole department mainly can be divided into following several types according to its mounted position and structural feature: (1) attached energy dissipation structures (such as rubber fender, anti-collision block, buffer block and the like); (2) self-floating suites (e.g., steel suites, etc.); (3) an independent anti-collision pier type (an independent guide post or a guide post and a sleeve box combined type and the like); (4) artificial islands, and the like. Wherein, the anti-collision facilities such as the attached energy dissipation structure and the self-floating type sleeve box generally have limited energy consumption capability and mainly need to bear the impact action of the ship by depending on the self anti-collision capability of the pier structure; independent anti-collision piers, artificial islands and the like have excellent protective capability, but the artificial islands seriously compress the channel sections.

Some very serious boat collisions that have occurred in recent years have shown that: the accident bridge is a double-column pier, and the ship is seriously damaged after being collided. This kind of pier structure is fine, structure self anti-collision ability is extremely poor, the attached form, from floating buffer stop can't satisfy actual anti-collision demand usually, and forms such as artificial island are obviously unrealistic in this kind of basin, anti-collision structures such as independent stake are through rational design, can effectively resist the forward striking effect of boats and ships, but can discover according to above-mentioned accident, during these serious boats and ships hit the accident, there is boats and ships side direction striking pier, cause the pier to produce along the bridge to the displacement and then cause the serious accident of roof beam that falls. Although such accidents occur frequently, the existing anti-collision facilities are difficult to effectively deal with the ship collision accidents.

In conclusion, a bridge in a wide water area (particularly a cross-sea bridge) needs to be a brand-new wind wave environment suitable for complex wind waves and can reliably work for a long time in severe weather; and another situation is that a large number of double-column type weak piers exist in the existing bridge, the risk of damage caused by front and side collision exists, the existing anti-collision device cannot effectively solve the protection problem, and an economical, reasonable and novel protection method and measure are needed.

Disclosure of Invention

The invention provides a ship interception system and application thereof, aims to overcome the defects and defects of the existing ship interception and anti-collision facilities in the background technology, provides a guide column-rotary drum-barrier net combined ship interception system which can adapt to severe weather environment and can reliably work for a long time in a wide water area, and simultaneously provides a new positive and side collision integrated protection idea and method for pier structures with poor anti-collision capacity such as a double-column type bridge and the like, thereby protecting the safety of bridge structures and ships.

In order to solve the technical problem, the invention adopts the following technical scheme:

the ship interception system comprises a plurality of blocking nets, independent guide columns fixed on the underwater ground and energy consumption cylinders sleeved outside the independent guide columns, wherein the blocking nets are fixed among the energy consumption cylinders.

The technical scheme is that the intercepting system of the blocking net, the independent guide post and the energy consumption cylinder is adopted, when a ship is intercepted by the intercepting system, the ship is firstly contacted with the blocking net, the kinetic energy of the ship pushes the blocking net to move, the movement of the blocking net generates extrusion on the energy consumption cylinder directly connected with the blocking net, and the energy consumption cylinder plays a main energy consumption role; when the energy consumption cylinders consume energy, the deformation and movement of the blocking net can drive a plurality of connected energy consumption cylinders at a distance to deform and consume energy, so that the combined intercepting effect of energy consumption and protection is achieved; compared with the existing floating body-blocking net-anchor block type intercepting system, the underwater landform intercepting system has small dependence on underwater landforms, and the blocking net and the energy consumption cylinder can be effectively fixed, so that the problems of failure of the intercepting system under the effects of ship intercepting loads and large storms and the like are solved.

As a further improvement of the above technical solution:

the energy consumption barrel comprises a water resistance energy consumption assembly, and the water resistance energy consumption assembly deforms after being stressed to increase the water resistance area. Through the optimization of the structure of the energy consumption barrel, the water resistance energy consumption assembly of the energy consumption barrel deforms after the energy consumption barrel is stressed, the cross section area in the vertical direction is increased, namely the water resistance area in the motion direction of the energy consumption barrel is increased, and the energy consumption effect of the energy consumption barrel on energy can be obviously improved.

The water resistance energy dissipation assembly comprises elastic filler and a corrugated elastic panel covering the surface of the elastic filler, and an elastic partition plate is arranged in the elastic filler. The further improvement on the structure of the water resistance energy dissipation assembly can ensure the realization of the function of increasing the cross section area of the water resistance energy dissipation assembly in the vertical direction after stress: when the elastic packing is stressed, the corrugated elastic panel and the elastic packing are subjected to pressure from water in the direction opposite to the impact direction, so that the elastic packing deforms and the corrugated elastic panel is unfolded, the water blocking area is increased, the energy consumption effect is enhanced, meanwhile, the elastic packing, the corrugated elastic panel and the elastic partition plate can provide a self-resetting function for the water blocking energy consumption assembly, and after the load is dissipated, the original appearance can be automatically restored without maintenance and replacement.

The energy consumption barrel further comprises an energy consumption interlayer and an impact panel; the water resistance energy dissipation assembly, the energy dissipation interlayer and the impact panel are fixedly connected in sequence from inside to outside of the energy dissipation cylinder. The impact panel, the energy dissipation interlayer and the water resistance energy dissipation assembly form a combined multi-stage energy dissipation sleeve, a multi-stage energy dissipation mode can be realized, under the action of wind waves such as typhoons and the like and the action of small impact interception of ships, the energy dissipation cylinder consumes energy by means of self-resettable water resistance energy dissipation components and automatically recovers after load dissipation; and when a large ship and the like are impacted, the water-blocking energy-consuming components are not enough to dissipate all kinetic energy, so that the blocking net further compresses the energy-consuming cylinders, the impact action is transmitted to the energy-consuming interlayer to dissipate the impact kinetic energy through the impact panel with excellent impact resistance, and the impact action is transmitted to the independent guide columns to further dissipate the energy, so that the stable operation of the ship intercepting system under the large impact action is ensured.

The independent guide post with the structure has higher overall rigidity, is convenient to construct, and can ensure the safety and reliability of the independent guide post under the action of large wind waves (such as typhoons) and ship impact.

And the top of the independent guide post is provided with a limiting device. The limiting device can prevent the floating energy-consuming cylinder from slipping off from the top of the independent guide post under the action of high water level and high wind waves.

The blocking net is provided with a plurality of floating bodies, and the floating bodies are provided with water blocking plates. The floating body can ensure that the barrier net between the two independent guide posts floats on the water surface, the effective interception height of the barrier net is ensured, meanwhile, when a ship collides with the barrier net, the vertical cable is pulled, the floating body is further dragged, the water blocking plate of the floating body can effectively utilize the damping effect on the water body to play an energy dissipation role, and therefore the floating body can also play an auxiliary energy dissipation role under the collision.

The energy consumption cylinders are provided with fixing devices, and the blocking nets are fixed between the energy consumption cylinders in an annular closed mode through the fixing devices. The design can ensure that after the ship impacts the blocking net at one position, the blocking net at the impacted position can move to drive the energy consumption barrel, so that the blocking net and the energy consumption barrel at other adjacent positions can be driven, the impacted load is transferred to the whole intercepting system, and efficient energy consumption is ensured.

The barrier net comprises a plurality of horizontal cables arranged in the vertical direction, the horizontal cables are connected through vertical cables, and locking adjusting devices used for adjusting the tightness of the barrier net are arranged on the horizontal cables.

Based on the same technical concept, the invention also provides an application of the ship interception system, and the ship interception system is applied to interception of non-navigation holes in large water areas or anti-collision of existing bridges.

Because the energy consumption cylinder 2 floats on the water surface and is formed by combining segment assembling technology, the energy consumption cylinder is convenient to replace and maintain after failure. In addition, the floating body 4 enables the water blocking plate 41 to generate a damping effect due to the movement of the barrier net 3, the floating body 4 plays a role in floating the height of the barrier net 3 and the like, more importantly, the effect of assisting energy consumption can be achieved in the collision process, the energy consumption way is the damping effect of utilizing the water body, and the energy consumption mode is environment-friendly.
