Description

Dredging operation system under wharf
Technical Field
The utility model belongs to the technical field of the engineering of dredging or ocean engineering technique field especially involve a pier below dredging operation system.
Background
With the rapid development of international trade, the construction and application of wharfs have received unprecedented attention. Among them, the high-pile wharf is an important structural form in modern wharf form, and has a wide application in areas such as downstream of rivers, estuaries and coasts.
The high-pile wharf belongs to a hollow structure and mainly comprises an upper structure and a pile foundation. The pile foundation of the high-pile wharf is a water-blocking structure, and the seabed in a certain range of an engineering area is scoured and silted due to the influence of the pile foundation on the power condition of a near-shore area in the pile foundation construction process and after the wharf is built. The monitoring results of a large number of high-pile wharfs show that the damping effect of pile foundation groups of the high-pile wharf reduces the local flow rate in pile foundations below the wharf, greatly reduces the sand-carrying capacity of water flow, causes serious sediment deposition below the constructed wharf, causes great damage to the high-pile foundations, and possibly causes phenomena of pile body fracture, wharf bearing capacity weakening, bank slope landslide or collapse and the like, particularly in the last 20 years, the sediment problem of the sediment below the wharf is quite serious, and the sediment quantity required to be cleaned is extremely large. In order to avoid the influence of the pressure of the deposited silt on the pile foundation of the wharf, the implementation of the cleaning and maintenance of the deposited silt below the wharf becomes very important and urgent.
Although the silt deposited at the front edge of the wharf can produce good effect by adopting the traditional dredging platform and equipment to carry out dredging. However, the pile foundation under the high pile type wharf has a complex structure and relatively high requirements for protection of pile foundation groups, so that the dredging working environment under the wharf is severe, the construction by using the traditional dredging platform and equipment is very difficult, and the related dredging equipment generally has the defects of backward technology, high energy consumption, low work efficiency, low slurry concentration, single function, poor adaptability to water depth and soil texture and the like. Meanwhile, the traditional dredging equipment needs related personnel to carry out field operation and construction under the wharf, and has larger potential safety hazard. Therefore, a set of efficient, energy-saving and safe novel dredging platform and equipment suitable for dredging below the wharf is researched and developed to have very important economic value and practical significance for dealing with the extremely large dredging market below the wharf.
Although research institutions at home and abroad research related dredging platforms and equipment, the research products are not limited to small-sized cutter suction vessels or sludge pumping dredging vessels with high-pressure flushing. For a small cutter suction dredger or a pump suction dredge with high-pressure flushing, the traction and positioning of a ship body are realized by adopting a positioning pile or a mode of manually pulling a steel wire rope to wind the positioning pile onto a pile foundation, and the ship body needs to be repositioned when moving forwards every time a period of construction is completed, so that the dredging construction efficiency is low, and the operation difficulty of the traction, positioning and dredging construction of the ship body is high and the personal safety guarantee of operators is low because the construction space below a wharf is limited (generally, the height from the water surface to the effective space of the wharf is about 2 m), and the frequency of the traveling wave and the water level change of the ship is high. Meanwhile, the technology of the dredging equipment is relatively lagged behind, the work efficiency is low, the energy consumption is high, the slurry concentration is low, the excavating depth is shallow, the adaptability to soil quality is poor, the automation degree is not high, and related operators are required to carry out real-time operation in a narrow space below a wharf, so that great personal safety hidden danger is easily generated for the operators who carry out construction below the wharf with limited space and severe environment.
