Description
Technical field
The utility model belongs to Soft Soil Subgrade Treatment Techniques field, applies in particular to for Combined Vacuum-surcharge Preloading
The furrow making dveice of work.
Background technique
Combined Vacuum-surcharge Preloading is a kind of method that vacuum preloading and piling prepressing combine and handle soft base,
It is gradually used widely in Expressway Ground Improvement in recent years.Piling prepressing is one of method of Soft Ground.
Preloading, that is, preloading drainage consolidation method.This method makes the pore water in the soil body along row by loading precompressed in place
The discharge of water plate, gradually consolidates, ground settles, while intensity steps up.Preloading has all kinds of soft foundations
Effect；Simple using material, equipment, constructing operation is convenient.But piling prepressing needs the regular hour, is suitble to construction period not tight
Project.For deep saturated soft soil, the time required for discharging consolidation is very long, while needing a large amount of heap carrier material, makes
With can be limited.Vacuum method is first to be laid with sand bedding course on the soft soil foundation surface to need reinforcement, then buries vertical drainage
Pipeline, then make itself and atmospheric isolation with air-locked close membrane, sealing film end carries out pile things on processing, by burying in sand bedding course
Suction piping, vacuumized using vacuum pump or other vacuum means, form it into negative pressure under film, increase ground has effect
Power.
In Combined Vacuum-surcharge Preloading construction, after being laid with sand bedding course, embedded drainage pipeline is needed.Embedded drainpipe it
Before, it needs to excavate pipe laying ditch on sand bedding course.Because construction area is usually very big, need to excavate the extremely huge pipe laying of quantity
Ditch.Major part ditching operation is artificial ditching at present, and construction efficiency is only about 300m/ work day, and labor intensity is larger and low efficiency
Under.And due to being mud below sand bedding course, the soil body is softer, easily caves in mining process, a pipe laying ditch often occurs
It not yet excavates and finishes, the soil for having excavated part just collapses, and has little time the situation of pipe laying.When additionally, due to excavating pipe laying ditch
Sealing press mold ditch is avoided, ditch spacing is smaller, and only about 1-2 meters.Although before the construction of deep vacuum preloading joint preloading, construction
Region is usually first handled through shallow-layer vacuum preloading, and bearing capacity is able to satisfy small-sized machine operation substantially, but existing excavator
Tool is excessive, is not suitable with so small ditch spacing or heavier, can not operation on soft soil foundation.Therefore it is badly in need of a kind of digging
Dig high-efficient, light quality, the excavator of small volume largely buries to meet quickly to excavate in Combined Vacuum-surcharge Preloading construction
The needs of pipe trench.
Summary of the invention
Based on this situation, the ad hoc meter of the utility model provides the furrow making dveice of tractive force by small hand tractor to solve
