Abstract
The invention relates to a vacuum preloading drainage assembly. The vacuum preloading drainage assembly comprises a drainage tube 3 and three or more drainage plates 4, and is characterized in that all the drainage plates 4 are arranged in a radial manner and share one side edge, the upper ends of the drainage plates 4 are connected with the drainage pipe 3 through a bow knot 1, and a plurality of holes 2 are formed in each drainage plate 4. When the vacuum preloading drainage assembly is adopted for construction, the assembly has the advantages of being large in water discharge capacity and short in construction period.
Description
Technical field
The present invention relates to a kind of vacuum preloading pumping equipment.
Background technology
With expanding economy, the nervous contradiction of coastal area urban infrastructure construction land used, therefore respectively
Big city has started the upsurge of one sea reclamation, and the barged-in fill that waterway dredging is formed often is used as the ground of sea reclamation
Base.But the deep hydraulic reclamation ultra-soft soil that dredging silt is formed, sticky content of its grain diameter less than 0.005mm 30%~
Between 50%, and with the bad geology such as high-moisture percentage, macrovoid ratio, low-intensity, high-compressibility, hypotonicity and rheology
Engineering Geological Characteristics.The foundation reinforcement method such as conventional surcharge preloading Loading method and heavy-tamping method cannot again dredging silt formed ground converge in
Use, therefore professor kjellman proposes vacuum method to solve the problems, such as the reinforcing of hydraulic reclamation super soft ground.
The vertical and transverse drainage passage that vacuum preloading before is used using to be sand drain carry out vertical and horizontal row
Water, vacuum preloading scene common at present, uses plastic draining board as vertical drainage passage, transverse drainage passage mostly
Using traditional sand bedding course or remove sand bedding course.
In engineering practice, the construction technology process of vacuum preloading is broadly divided into 9 construction steps.First, yard drain；If
There is ponding in place, it is necessary to the ponding in place is discharged；Second, laying woven cloth, mainly ensures construction safety, carry out every mud；
Third, laying non-woven geotextile, it is ensured that abundant every mud；Fourth, insertion plastic draining board；Fifth, plastic draining board and branch pipe phase
Even, branch pipe is connected with supervisor；Sixth, laying 2 strata vinyl chloride or polyethylene vacuum diaphragm；Seventh, being evenly arranged membrane in area
Device is simultaneously connected with steam knockout drum.Eighth, loading, monitoring；Ninth, unloading, detection.
A crucial ring of the plastic draining in whole work progress is inserted, but at present there is the following aspects in plastic draining board
Problem：
1st, displacement is small, and the duration is more long.Conventional plastic drain bar is one side discharge, because particle migration causes plastic draining
There is silting in plate, cause the cycle of vacuum preloading long, and engineering experience shows to increase the spacing of drain bar, although to a certain extent
The cycle of consolidation can be shortened, but drain bar spacing be less than 0.7m when, drainage effect is not still obvious.
2nd, injecting gas boosting, causes plastic draining board to keep vertical in mud clay, easily produces bending to be even broken
Phenomenon, influences vacuum preloading effect.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, with reference to site operation specific requirement, there is provided a kind of new true
Empty prepressing water discharge component, solves long construction period during site operation, and displacement is small, and drain bar bends and easily disconnected
The problems such as splitting.Technical scheme is as follows：
A kind of vacuum preloading drain assembly, including drainpipe 3 and the drain bar 4 of more than three, it is characterised in that each row
The radial arrangement of water plate 4, shares a side, and the upper end of drain bar 4 is connected by bowknot 1 with drainpipe 3, in each draining
Multiple holes 2 are offered on plate 4.
Preferably, described drainpipe is wired hose 3.Plastic slab support 5 is set on drain bar 4 every one section.
The present invention haves the advantages that the following aspects：
(1) displacement is big, short time limit.Drain bar is that four sides absorbs water simultaneously, accelerates consolidation rate, shortens vacuum preloading week
Phase, find that the drainage rates of the plastic draining board of new four sides draining are 3.6 times of left sides of conventional discharge plate by experimental study
It is right.
(2) overall performance is good, the board-like three-dimensional structure of novel plastic draining, can keep certain in mud is inserted
Perpendicularity, it is not easy to bending occurs and is broken, vacuum preloading effect is obvious.
Brief description of the drawings
Fig. 1 is the overall structure figure of vacuum preloading drain bar of the invention.
Label declaration in figure：1 bowknot；2 plastic draining plate holes；3 wired hoses；4 plastic draining boards；5 plastic slabs
Support
Specific embodiment
The present invention will be described with reference to the accompanying drawings and examples.
Referring to the novel evacuated prepressing water discharge component that Fig. 1, the present invention are provided, including multigroup plastic draining that four is a group
Plate.The connection of specific plastic draining board is：The plastic draining plate hole of multiple 0.01mm or so size is offered on plastic draining board 4
Hole 2, and plastic slab support 5 is set at 1m in plastic draining board 4；In work progress, plastic draining board 4 passes through butterfly
Knot 1 is connected to wired hose 3 each wired hose 3 and is connected to supervisor by threeway and branch pipe again.
