Description
Technical field
A kind of hydraulic reclamation district barged-in fill uniform deposition tapping equipment that the utility model relates to sea, river, lake dredging and reclamation make construction equipment field, ground.
Background technology
Along with economic fast development, Land Demand increases day by day, soil resource relative in short supply become a social very important difficult problem.So sea reclamation, land reclamation become the only way solving land resources shortage problem.
Barged-in fill has another name called dredger fill, is when renovating and dredge rivers river course, the sedimentary soil silt particle bottom river course or harbour formed by waterpower hydraulic reclamation with dredge boat or slush pump.In hydraulic reclamation process, sediment structure is destroyed, and the character of barged-in fill has that water content is high, void ratio large, contracting is high, shear strength is low, transmission coefficient is little, is generally softly to mould liquid-plastic state.The material composition of barged-in fill is usually comparatively complicated, and in most of the cases, the material of hydraulic reclamation is clay silt.Barged-in fill based on cohesive soil, containing a large amount of moisture in soil, and discharge difficulty, intensity could will improve after for a long time.The engineering properties of barged-in fill and sand grain form closely related: the barged-in fill that sand content is more, its consolidation situation and mechanical property better; The barged-in fill that argillaceous particle is higher, then belong to the under-compacted soil that intensity is lower and compressibilty is higher, its intensity and compressible index are all poor than similar natural long-pending soil more.Due to the separation in streaming current effect of barged-in fill in deposition process, coarse-grained soil is concentrated and is deposited on mud mouth, fine grained soil, away from mud mouth, causes hydraulic reclamation district grain composition extremely uneven.Sand, silt have good water permeability, and consolidation rate is very fast.Clay particle is often deposited on the place from the far withdrawal nozzle of mud mouth, exists with the form of mud.The long moisture evaporation in top layer will cause soil body volume-diminished and occur crack, and in silt district, common cracks width can reach 4-more than 5cm; Be deposited on below, then often exist with the form of mud, after construction terminates the several years, cohesive soil remains flow regime, and these clay consolidations are extremely difficult, generally can not be directly used in engineering construction, needs to carry out ground consolidation process.
Cause barged-in fill in the reason of hydraulic reclamation district nonuniform deposition: existing hydraulic reclamation mode adopts one or several hydraulic fill pipeline to be fixed on one or several position of fill area usually, when barged-in fill to be input to after hydraulic reclamation district goes out pipeline by pipeline, sediment movement is subject to the double action of turbulent fluctuation diffusion and gravitational settling, when Action of Gravity Field is better than turbulent diffusion, silt then sedimentation alluvial, under the impact of separation in streaming current effect, coarse sediment first deposits.At the hydraulic reclamation initial stage, water is husky always flows to the most low-lying place along the direction on abrupt slope, ground, hydraulic reclamation district, covering of the fan diffusion that to be then summit with outlet spout be, along with fluidized bed resistance increases, reduced velocity flow, first coarse sediment separates out precipitation from water, forms strong covering of the fan accumulation area around outlet spout, and follow that extension is raised in alluvial, swing and change of river course form advances to downstream, sediment deposit has thickness to replace the feature of interlayer.Water is husky in withdrawal nozzle transmittance process, and choke water control by withdrawal nozzle weir crest, flow velocity slows down along journey, silt has slightly to sink to subfractionation, in whole hydraulic reclamation process, withdrawal nozzle is choked water and is in low flow velocity district all the time and even occurs static current, is the concentration zones of fine sediment deposit buildup.In a word, this mode determines the inhomogeneities of barged-in fill deposition.
Because existing form of construction work causes the special generation type of aforementioned dredger fill, need to homogenize consolidation process to hydraulic reclamation district before construction in later period.Consolidation barged-in fill method is probably divided into two classes, one class is the method for physics, by impacting the soil body or making to occur pressure reduction in the soil body, pore water is discharged with this, more typically dynamic compaction, preloading, vacuum method and true dynamic consolidation method, High vacuum compacting method, fully enclosed stereoscopic formula vacuum drop water law based on vacuum method appearance, squeeze into preformed pile method, replacement cushion method, reinforcement method etc. in addition; Another kind of is the method for chemistry, and the method adds Admixture exactly in barged-in fill, and the material composition in Admixture and the soil body reacts, and makes soil solidifying.Relatively typical method is deep mixing method, powder spray piling method etc.The said method engineering time is long, and cost is high, and it is then often at a loss what to do for running into clay particle.
Utility model content
The purpose of this utility model brings the technical problem of consolidation, provides that a kind of structure is simple, easy to operate, use safety, cheap hydraulic reclamation district barged-in fill isotropic deposit tapping equipment.
The technical solution of the utility model is as follows:
A kind of hydraulic reclamation district barged-in fill isotropic deposit tapping equipment is: Bing Jie 2-5 road flexible pipe on sediment delivery pipe, the output port often propping up flexible pipe connects floatation device by support.
Such scheme comprises further: described floatation device is buoyancy tank or floating block, and described flexible pipe is plastic flexible pipe or water-band.
Described flexible pipe is connected by threeway and valve with sediment delivery pipe, the combining structure that every road flexible pipe adopts multistage to be connected by quick box cupling or snap, and the diameter of flexible pipe is 0.6-0.8 times of sediment delivery pipe diameter.
The buoyancy tank of described floatation device or floating block are hull shape, arrange balancing weight above.
This device has that structure is simple, easy construction, use safety, cheap feature, by branched flexible pipe dispersion hydraulic reclamation, hydraulic reclamation district barged-in fill homogeneous emission problem and dredger fill is solved because depositing the uneven basement process difficulty caused from source, thus create prerequisite for dredger fill consolidation process, can greatly reduce consolidation cost, reduction of erection time, have higher theoretical foundation and important economic benefit.
