If market presents rapid growth momentum, for ship dredging construction enterprise, the height of construction technology level and field management
Quality have become the important topic for being directly connected to enterprise's existence and development.In terms of large-scale dredging work, for mud and
The dredging of sandy seabed, the technique for having had comparative maturity at present, but for reef, rock class substrate, still lack the technical side of system
Case.Particularly navigation channel both sides waters is shallower and ditch is more, when driving anchor under conventional methods, if traversing cable releases long, clear cable
Overlong time；Conversely, traversing cable releases too short, hawser bears that resistance is little, and anchor is equally stopped incessantly.Due to project water price condition, lead
Construction cutter suction dredger transverse moving left and right anchor problem of " stopping and incessantly, easily drag of anchor " is caused to occur again and again.
The content of the invention
The present invention is provided stably to twist to inhale in a kind of pan soil matter construction to solve technical problem present in known technology and dug
The method of the traversing oscillation system of mud ship.
It is an object of the invention to provide a kind of have adaptable, simple, operation efficient, various informative, cost
It is cheap, easy to operate, applied range, can fast and stable cutter suction dredger traversing oscillation system, improve cutter suction dredger and apply
The traversing pendulum of stable cutter suction dredger in the pan soil matter construction of the features such as work time availability and Construction Productivity, increase economic benefit
The method of dynamic system.
The present invention is provided a method that for how cutter suction dredger stablizes traversing oscillation system in the construction of pan soil matter.
The present invention is located at about 37 kilometers of Karachi city the southeast based on Kasim port fire coal emergency power station projects, project
In place Kasim harbour industry park, close to Arabian Sea bank beach.Engineering construction area is located at Rhizophora apiculata Blume interior zone, and north side is
There is a mangrove in land, southern side, and construction area is not affected by stormy waves, ocean current substantially, is only subject to fluctuation tide to affect.Construction area does not have
Have enough open waters, billow is difficult development, trend is reversing current and flow velocity is fast, Chang Lang to for SW to, wave height is integrally less,
Usually phase wave is less than 0.3m, and it is 0.56m to meet within 50 years one wave H13%.Project Areas ocean current be reversing current, quayside Peak Flow Rate
