Description
Technical field
The present invention relates to a kind of harbour protection works, particularly to double ships of a kind of breakwater tub component to drawing location side
Method.
Background technology
The tub component of existing breakwater is a kind of novel anti-ripple using the materials such as concrete, reinforcing bar, steel construction to make
Embankment structure form, this class formation bottomless is made up of the anti-ripple tub component of the basic tub component covered and two by one.This structure
Tub component latent refute air supporting after dive by half, need after air supporting to be drawn to installation site.
Traditional caisson location uses big crane ship auxiliary, the air supporting principle of the tub component of this structure and the water of caisson to float
Difference, overall process leans on cabin internal gas pressure air supporting, and active force is the most all in vertical direction, due to crane ship it cannot be guaranteed that double hook active force
Uniformly and plus surging effect of current, bucket is under hanging power effect and shakiness, it is difficult to reaches safe, quickly position.
Summary of the invention
The technical problem to be solved is for the deficiencies in the prior art, it is provided that a kind of reasonable in design, user
Just, safely and fast, double ships of breakwater tub component are to drawing localization method.
The technical problem to be solved is to be realized by following technical scheme, and the present invention is a kind of anti-ripple
Double ships of dike tub component are to drawing localization method, and described tub component includes the bottomless Long Circle staving having lid and is located at oval
Two anti-ripple stavings above shape staving, anti-ripple staving is along the short-axis direction arrangement of Long Circle staving, and described Long Circle staving leads to
Crossing the separation of twice partition wall in length and breadth and have 9 separations, the top of each separation is equipped with steam vent and osculum, on two anti-ripple stavings
Erection has operating platform, and four angles of operating platform are provided with collection staving motion and the GPS data collection device of discrepancy in elevation data, behaviour
Making platform and be provided with the steam vent air bleeding valve one to one with separation top, steam vent passes through discharge duct and air bleeding valve phase
Connecing, the both sides of operating platform are respectively provided with several rows of water pump, and the osculum at separation top is connected with draining pump by drainage pipeline, its
Feature is, its step is,
(1) boats and ships are arranged: under the conditions of high tide level, arrange that in the side of tub component a master pulls ship, and opposite side arranges one
Station keeping ship, main ship, the center of station keeping ship and the tub component of pulling sets on the same line, and main pulling all configures on ship and station keeping ship
Having three groups of windlass, often group two, three groups of windlass on station keeping ship are respectively provided at centre and the two ends of station keeping ship, the often group anchor at two ends
Machine is connected by intersection hawser location anchor, and one group of middle windlass is connected with tub component by intersection hawser；Master pulls ship
On wherein two groups of windlass about arrange, often group is connected by two hawsers of opening location anchor, main pulls on ship additionally
One group is arranged in just fore to tub component, connects with tub component by intersecting hawser, joins with the windlass of station keeping ship centre
Close, it is achieved to tub component to drawing；At the main ship that pulls with under the cooperation of station keeping ship, tub component is slowly pulled to away from installation position
Put 40-60m, make tub component keep attitude, wait ebb；
(2) positioning at the beginning of tub component: along with tidal level declines, when the bottom of tub component is away from mud face 1.3-1.7m, master pulls ship
With station keeping ship drive tub component to installation site, tension is main to be pulled between ship and tub component, station keeping ship and tub component it
Between intersection hawser, now, tub component and station keeping ship, main pull the center of ship point-blank, continue waiting ebb, etc.
During time, the position deviation of variable interval monitoring tub component, by the intersection hawser on folding and unfolding two ship, tub component is just pulled to
Position；
(3) be accurately positioned, aerofluxus is sunk: tidal level declines, and when the bottom of tub component is away from mud face 0.5-0.8m, it is the most fixed to start
Position, according to the position deviation of tub component, is adjusted by the hawser that intersects between two ships with tub component, is being accurately positioned
While, the air bleeding valve on opening operation platform, tub component starts to sink under Gravitative Loads, notes tub in sinking watching
The balance of component, observes GPS reading, when tub component elevation difference everywhere is more than 15cm, comes by controlling capacity
Carry out leveling, after balance, resynchronize aerofluxus；
(4) tub component drainage sink: aerofluxus sinks down into after tub component touches mud, closes air bleeding valve, unties the main ship and fixed of pulling
The intersection hawser that position ship is connected on tub component, opening water discharge pump, it is ensured that the draining pump of each separation the most normally works, draining
Sinking watching continues observe GPS reading, as absolute altitude difference 15cm, carry out leveling by controlling displacement, after balance, continue
Continuous synchronization draining, negative pressure sinking, until bucket enters mud 2.0-3.0m, close each draining pump, sinking operation completes.
The technical problem to be solved can also be realized further by following technical scheme, described hawser
Front section connect nylon cable.
The technical problem to be solved can also be realized further by following technical scheme, station keeping ship two
The span of the location anchor that end intersects on hawser is more than 200m.
The present invention by double ships to drawing, the windlass on conservative control every station keeping ship, improve the positioning sinking of tub component
Precision, by the intersection folding and unfolding effect of intersection hawser, can make tub component smoothly carry out position adjustment, it is achieved precise positioning.
Compared with prior art, it is reasonable in design, and simple in construction is easy to operate, it is achieved that tub component safe, quick, stable
Location and installation.
