Description
Technical field
The present invention relates to using displacement hull carry out barged-in fill carry out stabilization by drainage, more particularly to a kind of hard and soft formula displacement hull and
Its construction method, handled suitable for the fast dewatering of the ultra-softs such as barged-in fill soil.
Background technology
As development especially " 12 " planning outline of economic construction of China is proposed after promoting marine economy development, edge
Requirement of the Haicheng City for border on the sea land-based area area and development rate is necessarily lifted, and causes the quantity and exploitation speed of reclamation engineering
Spend also fast development.Traditional reclaiming land around sea is typically used based on sand material, but by environmental protection, water conservancy safety and sand material price
Influence and yield.Filler used in China's reclamation engineering largely oozes for muck soil or organic matter clay etc. are weak at present
Permeability, high saturability, low-intensity, based on high rheological variation weakness barged-in fill, after the completion of hydraulic reclamation, the land-based area soil body is because of it in the short time
Moisture content is high, and intensity and bearing capacity are extremely low and can not carry out the relevant treatment of ground in time.Meanwhile China cruiseway lake
Pool, reservoir can all produce substantial amounts of dredging silt every year, and desilting mud is stacked to dry for a long time to be deposited to environment and land used resource
In certain pollution and waste.If the barged-in fill of hydraulic reclamation desilting quickly is carried out into draining, the minimizing processing of desilting is realized,
It is urgent problem to be solved.
For the reclamation engineering of blowing-filling sludge soil, need to have to the advance drainage sunk well of its super soft weak soil to be formed
The crust layer of some strength and thickness；For the dredging silt in stockyard, then need to carry out drainage sunk well to it to contain to reduce the soil body
Water rate.To sum up, above engineering problem is core is how quickly to reduce the moisture content of superficial layer mud, so as to realize barged-in fill
Deng the fast dewatering processing of ultra-soft soil.
At present, the Treatment Methods of high-moisture percentage barged-in fill mainly have：Firstth, natural drying：The method is typically dried and at least needed
Take 1 year and easily influenceed by weather, efficiency of construction is very low.Secondth, plastic draining board：Joined using plastic draining boards such as plastic draining boards
Close vacuum method and carry out drainage sunk well, plastic draining board can be retained in the soil body after changing method disposal, if outward transport minimizing is clear
Silt mud, white pollution can be caused.If stockyard need to repeatedly have enough to meet the need utilization, plastic draining board can not be applied multiple times, and cause to waste.The
3rd, rigid drainage body：By pre-setting rigidity in stockyard, vertically and horizontally drainage channel carries out vacuum dehydration processing to mud, this
Method can realize the recycling of displacement hull, but rigid pipe can not settle with the soil body, during vacuum dehydration, can because
Rigid drainage pipe it is exposed, cause vacuum to decline；Meanwhile rigid pipe water permeable area is small（Mainly by the permeable flower on rigid pipe
Hole）, drainage rates are less than seepy materials such as plastic draining boards.
To sum up, it would be highly desirable to a kind of displacement hull suitable for high-moisture percentage barged-in fill Quick drainage is researched and developed, and can be in vacuum preloading
Joint utilizes, and can realize and recycle and reuse.
The content of the invention

Both can be used displacement hull press-in die be placed on it is pending in super soft weak soil in, barged-in fill stockyard can also be pre-set at
In.The hard and soft formula displacement hull can realize recycling, while can be together with the soil body（Plastic draining board）Generation compression, true
Can be avoided in empty pre-compaction process because displacement hull is incompressible and caused by vacuum pressure can not be directly applied to soil body top layer.The row
Water body can be used in vacuum preloading operating mode, and can realize the partially recycled utilization of displacement hull, so as to reduce construction costs.With with
Lower advantage：Firstth, using the discharge structure of hard and soft formula, the recovery of rigid body after draining terminates, can be completed, reduces construction costs
And the wasting of resources；Second, top uses flexible water drainage structure, and in drainage procedure, displacement hull can occur to coordinate sedimentation with the soil body,
Can avoid because displacement hull is incompressible and caused by vacuum pressure can not be directly applied to soil body top layer.3rd, bottom is rigidly arranged
Water body uses internal permeable steel pipe, the structure of outside loaded filter, avoids because the flower hole aperture area of permeable steel pipe is too small, the row of causing
Water for prepressing is ineffective.
