Description
Technical field
The present invention relates to a kind of protect non-navigation bridge section block ship's repairs & maintenance facilities.
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, thus reduces ship impact force.This type of crashproof engineering services skill level is complicated, and construction and installation expense is higher.For non-navigation bridge section, under usual bridge, clear height is limited, needs 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 resistance that drags of anchor of gravity anchor is utilized to do the elastic-plastic deformation of negative work or cable body material to consume the kinetic energy of boats and ships, final prevention boats and ships move to bridge location, usually have overhead fixed, mooring floating, mooring and fixing hybrid.For overhead fixed and hybrid, its pile foundation support table does not possess the ability of bearing large ship and directly clashing into usually, 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 horizontal turn, and the lateral current power suffered by boats and ships after horizontal turn is much larger than the longitudinal drag force suffered by boats and ships, needs corresponding anchorage facility, construction and installation expense can be caused equally high, otherwise cannot effectively block boats and ships out of control.
Summary of the invention
Guaranteeing under the prerequisite of blocking effect, in order to reduce the construction and installation expense of blocking ship's repairs & maintenance facilities and the restoration costs after being hit by ship, adapting to tidal range, the depth of water and geological conditions better, the invention provides that the controlled floating foundation of a kind of resistance is overhead blocks ship's repairs & maintenance facilities.
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, bracing frame, arresting net, damping box and anchorage facility etc.Several floating foundation keep at a certain distance away setting, by piggy-back anchor and auxiliary anchor cable mooring, support arresting net by the bracing frame on floating foundation.Floating foundation arranges damping box, 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 component 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 permitted bearing capacity of Bower Anchor chain and damping chain, thus can protect damping chain and Bower Anchor chain not disrumpent feelings.
Arresting net is made up of main check cable, auxiliary check cable, connecting strand.Main check cable and auxiliary check cable are connected on the floating foundation at two ends directly or indirectly, therefore when a certain hole arresting net is subject to active force, and can by this force transmission to the floating foundation at these arresting net two ends, hole and on the arresting net of adjacent holes.When ship collision arresting net, drive floating foundation is moved 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 can provide metastable Resistance Value, consume boats and ships kinetic energy, the final boats and ships that stop move to bridge location.The resistance of damping chain is determined by the parameter such as specification, quantity of the rope that consumes energy, can according to the requirement design of blocking boats and ships.
After preventing being blocked horizontal turn of boats and ships, cause safety barrier to lose efficacy, jointly limit the horizontal gyration of boats and ships by multiple floating foundation and stop the motion after horizontal turn of boats and ships.When boats and ships directly clash into floating foundation, floating foundation will allow partially, thus boats and ships are finally applied on arresting net, and safety barrier can be prevented to lose efficacy.
The invention has the beneficial effects as follows:
The resistance of damping chain is controlled, and compared with the resistance dragged of anchor, the excursion of Resistance Value is relatively little, does not affect by geological conditions, and therefore safety barrier can protect boats and ships out of control better.Though there is part arresting net to act on bow, jointly limits the horizontal gyration of boats and ships by multiple floating foundation and stop the motion after horizontal turn of boats and ships, can not because being blocked the horizontal of boats and ships then being caused blocking unsuccessfully; Adopt floating foundation to support arresting net, SEA LEVEL VARIATION can be adapted to preferably and use in profundal zone, being convenient to transition and using and any spreading; Under the direct shock condition of boats and ships, partially will allow after floating foundation is stressed, safety barrier can not be caused to lose efficacy.

Detailed description of the invention
In FIG with in Fig. 2, floating foundation (1) is by piggy-back anchor (4) and auxiliary anchor cable (5) anchorage.Floating foundation (1) arranges damping box (6) and bracing frame (7), utilizes 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 arrange guide ring (9) at the shipboard that comes of floating foundation (1).When 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), floating foundation (1) motion will be driven 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, thus consuming boats and ships kinetic energy, the final boats and ships that stop move to bridge location.In the process of blocking, auxiliary anchor cable (5) is allowed to lose efficacy.
In FIG, 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 are arranged is auxiliary check cable (12).The rope of vertical setting is connecting strand (13).When blocking spitkit, the auxiliary check cable (12) of main dependence, connecting strand (13) play a role; When 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) can top large, below is little, concrete size needs the size according to blocking boats and ships to determine.
In figure 3, when 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) close can be blocked boats and ships, thus limit and blocked the horizontal gyration of boats and ships, reduce then the drag force that increase horizontal because of boats and ships.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 closer to being blocked boats and ships, and less by the horizontal gyration blocking boats and ships, 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) extremely can be relatively large by the distance of blocking boats and ships, 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, and safety barrier can provide enough counter-forces.
In the diagram, when boats and ships Transverse Impact arresting net (8), blocked boats and ships and be subject to larger lateral current power effect, more damping chain (10) will be pulled out, consume kinetic energy and the lateral current power institute work of 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 effectively blocking.
In Figure 5, the centre of power consumption rope (14) is around 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 in 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 is controlled by the bearing capacity of the rope that consumes energy (14), length and arrangement, needs the requirement design according to blocking boats and ships.In order to protect spitkit better, the several power consumption ropes played a role at first can select the cable body that Fracture Force is relatively less.The Resistance Value of damping chain (10) is less than the permitted bearing capacity of damping chain (10) and Bower Anchor chain (3), thus damping chain and Bower Anchor chain can be prevented to be pulled off.When recovering, damping chain (10) is reusable, and power consumption rope (15) needs to change.
