Description
Technical field
The invention belongs to dredging and reclamation technical field, more particularly to a kind of construction method of overlength basin slope excavating.
Background technology
First, basic condition
The development of China's dredging industry has the history of centuries, is quickly sent out in economic globalization tide and international trade
Under the promotion of exhibition, to adapt to the demand of container and tanker enlargement development, China various regions are built harbour, are widened simultaneously one after another
Deep coastal waterway is dug, to improve Navigation capacity, dredging industry has obtained quick development.At the same time, with harbour, navigation channel,
Irrigation and water conservancy and the development in coastal cities, dredging operation field have also obtained largely extending, from traditional harbor approach
Dredging and maintenance, rivers and lakes are administered and water conservancy projects is built, and successively expands to irrigation and water conservancy and reservoir construction and maintenance, national defence
The fields such as engineering construction, environmental protection dredging, land reclamation.
In future, China's dredging work industry will keep fast-developing, and in ship dredging construction, slope excavating construction will be more next
It is more.
The either dredging of port boat or water conservancy, the dredging of environmental protection aspect all suffers from a large amount of slope excavating, and overlength
The operating mode of slope excavating also will be more complicated.To handle these targets, it is necessary to improve waterway construction technical merit, navigation channel is accelerated to build
If with management modernization.Devoting Major Efforts To Developing is wanted using navigation channel canalization, regulation, dredging complete set technology；It is planned in waterway engineering, exploration,
In design, research, construction, management, implement science, specification, efficient dynamic and manage.Active adoption GPS, GIS remote sensing, communication,
The new and high technologies such as computer and control technology；Improve dredging vessel equipment level and dredging technology modernization level.
But at present for different soil properties and slope than excavation technology also lack the analysis of system, in particular for overlength
Slope excavating also lacks the scope of application of various process programs and reasonably defines, up for further studying.
2nd, existing construction method there are the problem of
The not analysis Jing Guo system of existing overlength slope construction, all slope excavatings mostly with same construction technology into
Row, being mostly need not be without effective construction organization, and planless guiding theory, science, does not be easy to cause the high cost operation of ship machine,
It is unfavorable for improving project progress.
Slope construction quality is checked and accepted as dredging work, and an important content of quality grade evaluation standard, is always thin
Dredge the most important thing of Engineering Quality Control.Slope construction quality problems are mainly reflected in two aspects, backbreak and owe to dig.
1st, it backbreaks, on the one hand can cause unnecessary useless side, influence the production efficiency of workboat；
2nd, the side slope near Special zone, such as shore protection, harbour, breakwater building is constructed, and is backbreak excessive, easily
Jeopardize the safety of building, form safety accident.
3rd, it owes to dig excessively, then need to move ship or ship is adjusted to carry out secondary excavation, not only reduce the production efficiency of workboat, simultaneously
Construction cost is also added, after carrying out secondary excavation, is also easily formed and backbreak.
4th, it twists and inhales ship construction operation, the depth and flatness quality in grooving are generally relatively easy to control, the construction quality of appearance
Problem is largely focused on slope excavating region.
Therefore, it is necessary to be proved in detail the various factors for causing to twist suction ship slope construction quality, seek solution and arrange
It applies.
