Abstract
A floating foundation overhead ship arresting facility with controllable resistance is composed of floating foundations, supporting frames, damping boxes, an arresting net, an anchorage system and the like. A damping chain and an energy consumption cable are arranged in each damping box. When a ship collides with the arresting net, the arresting net drives the floating foundations to move towards a bridge location, the damping chains are pulled out, and therefore kinetic energy of the ship is consumed, and eventually the ship is prevented from moving towards the bridge location. The resistance of the damping chains can be designed, so that the out-of-control ship can be well protected. Even though part of the arresting net acts on a bow, the transversely-rotating angle of the ship and motion after transverse rotating of the ship is blocked are limited through the multiple floating foundations together, and arresting failures caused when the arrested ship transversely rotates can not occur. The floating foundations are used for supporting the arresting net, and the floating foundation overhead ship blocking facility can well adapt to variation of the water level, and be used in an abyssal region and used for transition and any extension. Under direct collision of the ship, the floating foundations deviate after being stressed, and therefore the arresting facility cannot break down.
Description
Technical field
The present invention relates to a kind of ship's repairs & maintenance facilities that blocks of protecting non-navigation bridge section.
Background technology
At present, the anti-ship collision engineering services of known bridge, mainly contain two classes.
One class is arranged on bridge pier, utilizes the distortion of fender system, absorbs boats and ships kinetic energy, extends the effect of impact time, thereby reduces ship impact force.This type of crashproof engineering services skill level complexity, construction and installation expense is higher.For non-navigation bridge section, under bridge, clear height is limited conventionally, need to protect bridge pier and superstructure simultaneously, and this type of facility is difficult to play a role.
Another kind ofly be arranged on non-navigation bridge section and come outside the certain distance of shipboard, the elastic-plastic deformation of utilizing the resistance that drags of anchor of gravity anchor to do negative work or cable body material consumes the kinetic energy of boats and ships, the final boats and ships that stop move to bridge location, conventionally have overhead fixed, mooring floating, mooring and fix hybrid.For overhead fixed and hybrid, its pile foundation support table does not possess the ability of bearing the direct shock of large ship conventionally, if pile foundation support table is directly clashed into by boats and ships, may cause blocking unsuccessfully.For mooring formula and hybrid, in the process of blocking, boats and ships will inevitably horizontally turn, and the suffered lateral current power of boats and ships after horizontal turning is much larger than the suffered longitudinal drag force of boats and ships, needs anchorage facility correspondingly, can cause equally construction and installation expense high, otherwise cannot effectively block boats and ships out of control.
Summary of the invention
Guaranteeing to block under the prerequisite of effect, for reduce block the construction and installation expense of ship's repairs & maintenance facilities and hit by ship after restoration costs, adapt to better tidal range, the depth of water and geological conditions, the invention provides the overhead ship's repairs & maintenance facilities that blocks of the controlled floating foundation of a kind of resistance.
The technical solution adopted for the present invention to solve the technical problems is:
The controlled overhead ship's repairs & maintenance facilities that blocks of floating foundation of resistance is made up of floating foundation, arresting net, damping box and anchorage facility etc.The setting that keeps at a certain distance away of several floating foundation, by piggy-back anchor and auxiliary anchor cable mooring, is used for supporting arresting net.Damping box is set on floating foundation, in damping box, is provided with damping chain, power consumption rope, power consumption rope mount pad and power consumption rope steady pin.One end of damping chain is fixed on the member in damping box, and the other end is connected with Bower Anchor chain.One end of power consumption rope lies on the chain link of damping chain, and the other end is fixed on power consumption rope mount pad.The Resistance Value that damping chain can provide is less than the permission bearing capacity of Bower Anchor chain and damping chain, thus can protect damping chain and Bower Anchor chain not disrumpent feelings.
In the time of ship collision arresting net, will drive floating foundation to move to bridge location, owing to being subject to the constraint of Bower Anchor and Bower Anchor chain, damping chain is constantly pulled out, and the power consumption Suo Yici of One's name is legion is stressed and be pulled off, and metastable Resistance Value can be provided, consume boats and ships kinetic energy, finally stop boats and ships to move to bridge location.The resistance of damping chain is determined by the parameter such as specification, quantity of the rope that consumes energy, and can design according to the requirement of blocking boats and ships.
In order to prevent from being blocked, boats and ships are horizontal causes blocking facility after turning and lost efficacy, and jointly limit the horizontal gyration of boats and ships and stop that boats and ships are horizontal motion after turning by multiple floating foundation.In the time that boats and ships directly clash into floating foundation, floating foundation will allow partially, thereby boats and ships are finally applied on arresting net, can prevent from blocking facility and lose efficacy.
The invention has the beneficial effects as follows:
The resistance of damping chain is controlled, and compared with the resistance dragging of anchor, the excursion of Resistance Value is relatively little, not affected by geological conditions, therefore blocks facility and can protect better boats and ships out of control.Though there is part arresting net to act on bow, jointly limit the horizontal gyration of boats and ships and stop that boats and ships are horizontal motion after turning by multiple floating foundation, can be because being blocked the horizontal of boats and ships then cause blocking unsuccessfully; Employing floating foundation supports arresting net, can adapt to preferably SEA LEVEL VARIATION and use in profundal zone, is convenient to transition and uses and any spreading; Under the direct shock condition of boats and ships, after floating foundation is stressed, will partially allow, can not cause blocking facility and lose efficacy.

The specific embodiment
In Fig. 1 and in Fig. 2, floating foundation (1) is by piggy-back anchor (4) and auxiliary anchor cable (5) anchorage.Damping box (6) and bracing frame (7) are set on floating foundation (1), utilize bracing frame (7) to support arresting net (8) and reach design height.Floating foundation (1) can be monomer, binary or multiple hull construction, if adopt the floating foundation (1) of binary or multiple hull construction, need guide ring (9) be set at the shipboard that comes of floating foundation (1).In the time that boats and ships directly clash into floating foundation (1), will first hit the side of or floating foundation (1) upper at guide ring (9), promote floating foundation (1) and partially allow, final boats and ships will be applied on arresting net (8).When ship collision arresting net (8), to drive floating foundation (1) motion by arresting net (8), owing to being subject to the constraint of Bower Anchor (2) and Bower Anchor chain (3), damping chain (10) is constantly pulled out, thereby consume boats and ships kinetic energy, finally stop boats and ships to move to bridge location.In the process of blocking, allow auxiliary anchor cable (5) to lose efficacy.
In Fig. 1, arresting net (8) is made up of main check cable (11), auxiliary check cable (12), connecting strand (13).Main check cable (11) is generally the check cable of the top in arresting net (8), and the check cable that all the other horizontal directions arrange is auxiliary check cable (12).The vertical rope arranging is connecting strand (13).In the time blocking spitkit, main auxiliary check cable (12), the connecting strand (13) of relying on plays a role; In the time blocking large ship, main check cable (11), auxiliary check cable (12), connecting strand (13) play a role jointly.Therefore, for reducing the deadweight of arresting net (8) and suffered wind active force, the bearing capacity of main check cable (11) is often greater than the bearing capacity of auxiliary check cable (12), the grid of arresting net (8) is can top large, below is little, and concrete size needs to determine according to the size of blocking boats and ships.
In Fig. 3, in the time of boats and ships longitudinal impact arresting net (8), the damping chain (10) of impingement position both sides is constantly blocked out, make floating foundation (1) be blocked boats and ships near quilt, thereby limit the horizontal gyration that is blocked boats and ships, reduced drag force horizontal because of boats and ships then that increase.For large ship, because its kinetic energy is large, the length that damping chain (10) is drawn out is longer, and floating foundation (1) can block boats and ships by more close quilt, and the horizontal gyration that is blocked boats and ships is less, and the amplitude that drag force increases is also corresponding little.For spitkit, because its kinetic energy is little, the length that damping chain (10) is drawn out is less, floating foundation (1) to the distance of being blocked boats and ships can be relatively large, being blocked the horizontal gyration of boats and ships also can be more greatly, but because the horizontal current obstruction area of spitkit is relatively less, suffered lateral current power is also corresponding little, blocks facility enough counter-forces can be provided.
In Fig. 4, in the time of boats and ships Transverse Impact arresting net (8), being blocked boats and ships is subject to larger lateral current power effect, to pull out more damping chain (10), the kinetic energy and the lateral current power institute work that have consumed boats and ships on the one hand, jointly stop lateral drift boats and ships by multiple floating foundation (1) on the other hand, enough resistances can be provided, realize and effectively blocking.
In Fig. 5, the centre of power consumption rope (14) is on the chain link of damping chain (10), and the two ends of power consumption rope (14) arrange claim-reduction, utilizes spacer pin to be fixed on power consumption rope mount pad (15).When damping chain (10) is drawn out, many power consumption ropes (14) are successively pulled off, and its resistance, by bearing capacity, length and the arrangement control of the rope that consumes energy (14), needs according to the requirement design of blocking boats and ships.In order to protect better spitkit, the several power consumption ropes that play a role at first can be selected the cable body that Fracture Force is relatively less.The Resistance Value of damping chain (10) is less than the permission bearing capacity of damping chain (10) and Bower Anchor chain (3), thereby can prevent that damping chain and Bower Anchor chain are pulled off.In the time recovering, damping chain (10) is reusable, and power consumption rope (15) needs to change.
