Abstract
The invention relates to a ship blocking method capable of defusing a transverse rotating risk of a ship. The method has the characteristics that only strong blocking cables in blocking nets can pull gravity anchors to drag away under impact of the yawing ship; however, medium blocking cables and lower blocking cables only exert cable accompanying effects, can pull the strong blocking cables on a ship deck, and do not have the bearing capacity to pull the gravity anchors to drag; when the yawing prow is drilled into blocking net grids, the medium blocking cables, the lower blocking cables and connecting cables which block movement of the ship are fractured at a certain part, so that the strong blocking cables finally exert the effect on an upper part structure of the middle rear part of the ship; the blocked ship can be prevented from moving towards a bridge position downstream again after rotating transversely; the blocking for the yawing ship is achieved really; the safety of a bridge is protected; and when a blocking facility consists of a plurality of blocking units, the blocking facility can have the ship with a blocking impact force greater than the impact resistance of end part support frames in a manner that the end part support frames of the two adjacent units are staggered, so that the construction cost of the blocking facility is saved greatly.
Description
Technical field
The present invention relates to a kind of boats and ships method for arresting, especially relate to a kind of horizontal boats and ships method of blocking that turns risk of boats and ships of dissolving.
Background technology
At present, about the anti-ship problem of hitting of non-navigation bridge, become one of study hotspot of engineering circles, published pertinent literature is more, and major part is that boats and ships are blocked in the energy dissipating that drags of anchor by gravity anchor.
When boats and ships are sailed against the current, easily handle, even break down, also relatively easily process, be difficult for clashing into the bridge in the place ahead; When boats and ships are sailed with the current, if driftage very easily causes dangerous situation and major accident.Therefore, most ships hit the bridge accident and occur in the period of sailing with the current.When blocking facility and only act on bow, after even boats and ships are blocked and are stopped, but under the effect of the bonding forces such as bourn acting force, boats and ships turn horizontal, and the lateral current active force that the boats and ships after horizontal turning are subject to will be vertical bourn acting force decades of times, as when the flow velocity 2.5m/s, the lateral current active force that 3 kilotons, 5 kilotons and 1 ton boats and ships are subject to can reach respectively 3100kN, 4200kN and more than 5800kN, need to block facility and have the ability of blocking accordingly, otherwise the boats and ships after horizontal turning will threaten the bridge in the place ahead again.More disadvantageously, in blocking the boats and ships process, the gravity anchor that the two ends of arresting net have been sunk under water is strained, and arresting net only acts on bow, boats and ships are horizontal turn over journey in stern will first cross the arresting net that sunk, then the whole piece ship is crossed arresting net, following current is moved to bridge location again.Comprise domestic built facility and the published pertinent literature of blocking, only have the described arresting system of patent of invention ZL200510095592.0 could finally block boats and ships by the gravity anchor that corresponding resistance requirement can be provided is set, all the other methods are the not anti-horizontal ability that turns of boats and ships all.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of horizontal risk rather than horizontal boats and ships method of blocking that turns of opposing boats and ships of turning of boats and ships of dissolving.
The technical solution adopted for the present invention to solve the technical problems is: a kind of horizontal boats and ships method of blocking that turns risk of boats and ships of dissolving comprises the following steps:
(1) keep at a certain distance away, the end support shelves that pile foundation, cushion cap and upper bracket form two ends is set;
(2) supplemental support of some quantity is set on the line of end support shelves;
(3) strong check cable, middle check cable, lower check cable, connecting strand are connected into to arresting net, then be installed on end support shelves and supplemental support;
(4) gravity anchor is installed, and is connected with the strong check cable in arresting net by anchor chain or anchor cable.
End support shelves and between supplemental support, arresting net, anchor chain or anchor cable, gravity anchor form one and block unit.Because the length of blocking unit always is subject to certain condition restriction, when the single unit that blocks can not meet while blocking the requiring of total length, can meet by several arrangements of blocking unit.When long when blocking facility and blocking unit and rearrange by several, if not possessing opposing, end support shelves need not block the ability that boats and ships directly clash into, adjacent two end support shelves of blocking unit are crisscross arranged, the boats and ships that make to go off course can only knock wherein 1 place's end support shelves down, thereby can prevent that boats and ships from crossing defence line from two joint portions of blocking unit, guarantee to block effect.When end portion supports possesses corresponding impact resistance, adjacent two block unit can share 1 place's end support shelves.
Set end support shelves, major function are to support arresting net to reach design height, and possess certain impact resistance.
Set supplemental support, be generally single stake, can set up in case of necessity the anchorage facility and improve lateral bearing power, and major function is vertically to lift arresting net, and bears the arresting net lateral force that causes because of wind pressure, bourn acting force.After supplemental support was knocked down by boats and ships, arresting net just highly descended.If it is shorter to block the length of unit, the end support shelves at two ends can only be set, and supplemental support is not set.
For reducing after ship hits the restoration costs of blocking facility, on end support shelves and supplemental support, be respectively equipped with and weakly be connected to install arresting net, arresting net can separate with supplemental support with end support shelves after ship collision.
Strong check cable used, can be single, also can be many, needs to require to select strong check cable according to the maximum check cable tension force that may form under the boats and ships effect, and major function is that the traction gravity anchor drags of anchor.
The middle check cable that uses, lower check cable play companion Suo Zuoyong, can strong check cable be drawn and fall on ship deck by connecting strand, but not possess the desired supporting capacity that drags of anchor of drawing gravity anchor.
The height of the strong check cable lowest part that the water surface is above, higher than the height of bow, and have certain height more than needed.If in the middle of boats and ships directly knock down, after 1 place's supplemental support, the height of strong check cable lowest part will descend, but still higher than the height of bow, thereby guarantee that strong check cable can be applied to the superstructure of boats and ships postmedian.
The gravity anchor that adopts, be usually placed in the two ends of blocking unit, often the gravity anchor group of a plurality of gravity anchors compositions.For preventing that gravity anchor is embedded in mud, gravity anchor is placed in to the cushion cap top of end support shelves or hangs on the side-lower of end support shelves.If block the middle part of unit, increase the gravity anchor be used to the energy dissipating that drags of anchor, also need to take corresponding measure.
The invention has the beneficial effects as follows, Upper Structure by strong check cable and boats and ships postmedian, the traction gravity anchor drags of anchor and does negative work consumption boats and ships kinetic energy, thereby prevent the boats and ships that blocked after the External Force Acting bottom rails such as current turn again following current to bridge location, move, real realization is blocked the driftage boats and ships, the safety of protection bridge; By adjacent end support shelves of blocking unit, can block the boats and ships that impact surpasses end support shelves self impact resistance, significantly save the Facilities Construction expense of blocking.

The specific embodiment
A kind of horizontal boats and ships method of blocking that turns risk of boats and ships of dissolving comprises the following steps:
1. keep at a certain distance away, the end support shelves that pile foundation (1), cushion cap (2) and upper bracket (3) form two ends is set;
2. the supplemental support (4) of some quantity is set on the line of end support shelves;
3. strong check cable (5), middle check cable (6), lower check cable (7), connecting strand (8) are connected into to arresting net, then be installed on end support shelves and supplemental support (4);
Gravity anchor (9) 4. is installed, and is connected with the strong check cable (5) in arresting net by anchor chain or anchor cable (10).
In Fig. 1, pile foundation (1), cushion cap (2) and upper bracket (3) form the end support shelves at two ends; Strong check cable (5), middle check cable (6), lower check cable (7), connecting strand (8) connect into arresting net; Gravity anchor (9) is connected with the strong check cable (5) in arresting net by anchor chain or anchor cable (10).End support shelves and between supplemental support (4), arresting net, anchor chain or anchor cable (10), gravity anchor (9) form one and block unit.Long block unit some places supplemental support (4) may be arranged, the shorter unit that blocks can not arrange supplemental support (4).Strong check cable (5) used, can be single, also can be many, needs to require to select strong check cable (5) according to the maximum check cable tension force that may form under the boats and ships effect, and major function is that traction gravity anchor (9) drags of anchor.The middle check cable (6) that uses, lower check cable (7) mainly play companion Suo Zuoyong, energy draw strong check cable (5) to fall on ship deck by connecting strand (8), but does not possess the desired supporting capacity that drags of anchor of traction gravity anchor (9).The height of strong check cable (5) lowest part that the water surface is above, higher than the height of bow, and have certain height more than needed.If in the middle of boats and ships directly knock down, after 1 place's supplemental support (4), the height of strong check cable lowest part will descend, but still higher than the height of bow, thereby guarantee that strong check cable (5) can be applied to the superstructure of boats and ships postmedian.
In Fig. 2, gravity anchor (9) is generally several, is placed on cushion cap (2) top of end support shelves or hangs over cushion cap (2) side-lower.
In Fig. 3, when end support shelves does not possess the corresponding ship collision ability of opposing, adjacent two end support shelves of blocking unit are crisscross arranged, perpendicular to come the ship to overlap length greater than the width of the boats and ships of setting up defences, the boats and ships that make to go off course can only bump against 1 place's end support shelves at the most; Be parallel to come the ship to longitudinal separation greater than the height of end support shelves, even front-seat end portion supports is knocked down, do not affect rear row yet and block unit and play a role.Simultaneously in connection with the gravity anchor (9) of section, by long anchor chain or anchor cable (10), being set to rear row's end support shelves does not affect the position that it drags of anchor, and usually can place above the cushion cap (2) of rear row's end support shelves or hang over outside the cushion cap (2) of rear row's end support shelves.In order to prevent the whole end support shelves of blocking the starting point of facility of ship collision, to near navigation channel, arrange near the end support shelves in navigation channel as far as possible, in bridge, the headroom of first non-navigable in close navigation channel is higher, even there are boats and ships to pierce, be only also top and the bridge superstructure effect of boats and ships mast, can not threaten bridge security; To be arranged on away from the end support shelves of the navigation channel other end outside the scope that boats and ships may clash into, reduce the possibility of directly being clashed into by boats and ships.
When the driftage boats and ships directly clash into supplemental support (4), supplemental support (4) will lose efficacy, under the Action of Gravity Field of arresting net, the height of main check cable (5) lowest part will descend, but still higher than the height of bow, boats and ships move on, and will clash into arresting net.
When driftage ship collision arresting net, middle check cable (6) or lower check cable (7) first are subject to the boats and ships active force, then by connecting strand (8), strong check cable (5) are drawn and fall the ship deck top.at boats and ships, continue in the process of bridge location motion, bow will creep into the grid of arresting net, due to middle check cable (6), lower check cable (7) and connecting strand (8) do not possess traction gravity anchor (9) the required supporting capacity that drags of anchor, the middle check cable (6) that the restriction boats and ships advance, lower check cable (7) and connecting strand (8) will be disrumpent feelings at certain position, bow will pass the grid of arresting net, strong check cable (5) will with the Upper Structure of boats and ships postmedian, this moment, bow was front, force part is at the boats and ships postmedian, thereby boats and ships can horizontally not turn under the following current condition, and consume boats and ships kinetic energy in the process that check cable (5) traction gravity anchor (9) drags of anchor by force, the final boats and ships that stop move to bridge location.
