Description
Technical field
The present invention relates to a kind of plastic draining boards handled for soft soil foundation precompressed, in particular to a kind of includes waveform
Quilted plastic panel and the degradable novel plastic drain bar for having through-flow conduit, belong to geotechnical engineering field.
Background technique
During civil engineering infrastructure is built, it is frequently encountered deep soft clay foundation.It is this soil intensity and
Permeability is low, deformation is big, processing must be carried out to it before development and utilization could be as building/the ground of structures.Common ground
Base processing method includes cushion, heavy-tamping method, vibroreplacement, draining concretion method and deep mixing method etc..Wherein, draining is solid
Connection is various drainage conditions to be added in ground, and apply prefabricating load, with a kind of ground for accelerating saturated soft clay to consolidate
Processing method is used widely in large-area soft ground processing.During soft base discharging consolidation, common plastic row
Water plate is made of quilted plastic panel and the filter membrane being wrapped on the outside of quilted plastic panel, quilted plastic panel be in mouth organ type, by board-plugging device with
Plastic draining board is inserted into Soft Soil Layer by certain spacing distance.Plastic drain-pipe forms capillary drainage channel in soil layer,
Under the effect of plate end prefabricating load, underground water can enter plastic plate through filter membrane and be then discharged in the layer of sand of top place mat, then use water
Water in layer of sand is discharged pump, to realize the acceleration consolidation of Soft Soil Layer.This method need earth working material is more, higher cost,
Duration is longer, and the drainage effect of mouth organ type drain bar is not fine in the drainage procedure of the grounds such as mud, rinse fill；Together
When, conventional plastic draining board is difficult to degrade, and long-term existence still has drain function, can make engineering in soil after the completion of engineering
The lasting sedimentation of deuterogenesis and differential settlement.
Summary of the invention
The purpose of the present invention is draining board defect for current common plastics, it is bigger to provide a kind of water-flowing amount, drainage performance
More preferably, intensity is higher and can voluntarily degrade and lose drainability to avoid later period ground from continuing the plastic row of discharging consolidation
Water plate.
The technical scheme adopted by the invention is that: a kind of degradable novel plastic drain bar, including quilted plastic panel and packet
It is rolled in the degradable permeable filter membrane in outside, drain bar lower end is provided with plastics insert box.Quilted plastic panel forms rhone, the plastics
It is provided in core plate and increases whole draining flux, promote plastic draining board integral strength, expand plastic draining board allomeric function
Through-flow conduit；The through-flow longitudinally through quilted plastic panel of conduit, and tube wall is provided with equally distributed permeable hole；The permeable filter membrane is excellent
Choosing is made of flax material, by hot melting cohesion on quilted plastic panel.
The quilted plastic panel is wavy, is made up of polypropylene.
The upper end (even if used time be located at ground or more one end) of the through-flow conduit is mutual by hose and water header
Connection, so that drain bar can also serve as Application of light well point precipitation device.
Ponding space is equipped in plastics insert box, ponding space is connected with through-flow conduit and external collecting conduit.
The diameter of the center conduit is preferably 1~2cm.
The invention has the advantages that
1. the integral strength of drain bar of the present invention enhances, manufacture more convenient.Traditional mouth organ plastic drain bar entirety class
It is similar to thin slice, is easily broken off when being inserted into harder ground, and the through-flow conduit of 1~2cm is set in the middle part of this plastic draining board, one
Determine the integral thickness for increasing drain bar in degree, improve its integral strength, ensure that plastic draining board can be inserted into design
Depth, eliminates hidden danger present in engineering, and reliability greatly improves.
Ponding sky is arranged by the through-flow conduit in 1~2cm of intermediate setting in the present invention in the plastics insert box of lower part
Between, and ponding space and the drainage channels such as through-flow conduit and external collector pipe penetrate through, and can not be laid with sand pad in foundation surface
Directly water is discharged from quilted plastic panel in the case where layer, close membrane, the function of Application of light well point precipitation is realized, improves engineering
Convenience.
2. the filter membrane of drain bar of the present invention uses flax degradation material, voluntarily degrade after a certain period of time being buried in the earth,
Core plate gap stops draining by soil compaction, plastic draining board, effectively inhibits the later period soil body to continue to drain and settle, together
When will not to environment generate pollution.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is cross-sectional structure schematic diagram of the invention.
Fig. 3 is front view of the invention.
Specific embodiment
Referring to attached drawing, a kind of degradable novel plastic drain bar, including quilted plastic panel 2 and be wrapped in outside quilted plastic panel 2
Permeable filter membrane 1 made of degradable flax material of side, the permeable filter membrane 1 pass through hot melting cohesion technique and the quilted plastic panel
2 are integrated, and can efficiently solve permeable filter membrane 1 in the common suture type of engineering and adhered equal connection methods and wrap up not enough
Close caducous problem, improves the stability of drain bar structure.
The wavy arrangement of the quilted plastic panel 2, provides higher-strength, quilted plastic panel while can simplify manufacturing process
Groove on 2 is the rhone being arranged.The through-flow conduit 3 of longitudinally through quilted plastic panel is provided in the middle part of the quilted plastic panel,
Permeable hole 4 is evenly distributed on the through-flow conduit 3, through-flow 3 diameter of conduit is 1~2cm, the drain bar bottom setting
There is plastics slot 5, is equipped with ponding space among the plastics slot 5.At work, the water in the soil body can not only lead to drain bar
It crosses permeable filter membrane 1 and enters the rhone discharge soil body set on quilted plastic panel 2, while permeable filter membrane 1 can also passed through
Enter after the permeable hole 4 of through-flow conduit 3 simultaneously and the soil body is discharged through through-flow conduit 3, while the part water in the soil body can pass through
Plastics slot 5 is entered eventually into through-flow conduit 3 along rhone or process permeable hole 4 after permeable filter membrane 1 to be formed by
In ponding space, moisture can directly be discharged from the soil body in the case where no sand bedding course.
The setting of the through-flow conduit 3 can both increase plastic draining board structure integral strength, while guarantee plastic draining
Plate can be inserted into projected depth, while also increase the cross-sectional area of drainage channel, can equally mention in the blocking of partial drainage slot
Supply and discharge aquaporin makes drain bar be unlikely to lose drain function.In addition, through-flow 3 top of conduit can by hose directly with catchment
General pipeline connection, so that drain bar also serves as Application of light well point precipitation device.
Permeable filter membrane 1 is flax degradation material in the present invention, permeable after being discharged underground water 1 year using this drain bar
Filter membrane 1 can voluntarily degrade, and most of channel of plastic draining board is blocked, and lose drain function, and ground stops consolidation decline, together
When will not pollute environment.
Content described in this specification embodiment is only enumerating to the way of realization of inventive concept, protection of the invention
Range should not be construed as being limited to the specific forms stated in the embodiments, and protection scope of the present invention also includes art technology
Personnel conceive according to the present invention it is conceivable that equivalent technologies mean.
