Lotus is up to 8000~10000 tons.To prevent that ground is punctured, cause platform inclination or even tumble.Precompressed is carried out using ballast water
Very slow, the ballast tank of measurement tons up to ten thousand is also difficult to, and can only use main under " the diagonal pressure " of two leg stress, this state
Hull stress greatly, causes Ship Structure increase weight hundreds of or even upper kiloton.Even if the large-scale shoe equipped with 100 square meters, soft
Native condition often also needs tens of rice to insert could provide enough bearing capacities deeply, not only add on the length of spud leg, rack band
Silt has a strong impact on the lifter wheel life-span.Under extreme condition, in some instances it may even be possible to can be inadequate because of spud leg length or oversize cause intensity not
Foot can not realize operation.

Pressure lower greatly.Absorption affinity, soil cohesive strength, side friction and the soil that also overcome shoe bottom to bear pore water pressure formation simultaneously are cut
Cut destructive power.When slotting depth is deeper, pile pulling power is very big, and pile pulling is extremely difficult.High pressure water flushing stake can supplement shoe bottom pore water,
Eliminate negative-pressure sucking.But when shoe inserts deeper in mud, soil strength is very high, rushes stake difficulty also very big.Under special circumstances,
Possibly even rush motionless stake.The buoyancy overcoming pile pulling power of ship, the progress of one one are borrowed during pile pulling.Time and effort consuming, pile pulling
When encountering difficulties, a few days, 1~2 week, or even longer (having case to expend 10 time-of-weeks) may be needed.Sometimes still pull out not by every possible means
Go out, have no alternative but that shoe have to be sliced off.In weak soil marine site, in some instances it may even be possible to have influence on undertaking installation task, air exercise because pile pulling is difficult
It is undoubtedly a big restrictive condition for stake ship.
Efficiency and risk：According to investigation, when pitching pile formula pile driving barge operation is smooth, a pile is averagely made a call to about 1 week or so.In shale
Under the conditions of, plug piling can account for for 1/3~1/2 activity duration, and when meeting difficulty, the time is more uncontrollable.When pulling out
When stake is difficult, not only existence time is consumed, and as uncontrolled uncertain state.At sea need to face daily
The conditions such as flood tide, ebb tide and the stormy waves of change, not only add load and the life-span of jacking system, and the risk of whole ship is also greatly
Increase.
It was found from above-mentioned analysis, plug stake process is the link most taken time and effort in pile driving barge operation process, but it is made
With the job platform for being only offer stabilization.If the process of stake can be avoided plugging on the premise of platform stabilization is ensured, to improving
