Abstract

The utility model discloses the plastic water draining device used in a kind of Soft Ground, be made up of plastic drain-pipe, base and cloth bag.Base sheath, in the bottom of plastic drain-pipe, forms an entirety.Base can ensure the horizontal and vertical degree of plastic drain-pipe, and protects not squeezed evil idea bottom plastic drain-pipe to damage by pressure.Cloth bag is tightly wrapped in the outside of single unit system, plays the effect of filtering soil particle.This plastic drain-pipe is face upper channel draining, and pore water is discharged from surrounding entering surface upper channel, is different from the tube chamber internal drainage of other plastic drain-pipes.What is more important plastic drain-pipe is axially symmetric structure, more can cater to the dissipation law of pore water pressure, makes pore water from surrounding discharged to plastic drain-pipe, can reach good drainage effect.The utility model combines the advantage of sand drain and plastic draining board, has started plastic water draining device, has improve drainage effect, has the advantages such as structure is simple, cost is lower, effective simultaneously.

Description

Packed plastic water draining device

Technical field

The utility model belongs to field of foundation treatment, relates to a kind of plastic water draining device.

Background technology

Consolidation is widely used as a kind of basic theories of basement process, and its representative engineer applied has vacuum method, preloading.Wherein vertical drainage body mainly contains two classes, and a class is sand drain or sand wick, and another kind is plastic draining board.These two kinds of water discharging bodys have respective pluses and minuses, the draining of sand drain surrounding, formula draining axisymmetricly, and draining is reasonable and speed is fast, but construction is more complicated, and speed of application is slow, and cost is higher.Plastic draining board is simple and convenient, and the duration is shorter, and cost is lower.But plastic draining board is plane structure, can only one direction draining, cannot meet the demand of surrounding draining, draining is uneven, drainage effect is affected, and the shape of band drain is single, and bulk strength is not high, easy distortion bending, makes drainage path be obstructed, affects drainage effect.

Utility model content

Technical problem: the utility model provides one to combine sand drain and plastic draining board advantage, the feature of existing sand drain surrounding draining, there is again band drain easy construction, the feature that the duration is shorter, reach the packed plastic water draining device of better drainage effect and economic interests.

Technical scheme: packed plastic water draining device of the present utility model, the cloth bag comprising plastic drain-pipe, be enclosed within base bottom described plastic drain-pipe, be wrapped in described plastic drain-pipe and base exterior, the outer wall of plastic drain-pipe is provided with axial drainage groove.

In preferred version of the present utility model, plastic drain-pipe is provided with the drain hole with drainage groove in communicating pipe, in drainage groove, fills up dank material.

In preferred version of the present utility model, base is provided with the groove for being snapped in by plastic drain-pipe wherein.

In preferred version of the present utility model, cloth bag is the long bag of permeable geotextile.

Beneficial effect: compared with prior art, the utility model has the following advantages:

This plastic drain-pipe is face upper channel draining, is different from the tube chamber boring draining of other plastic drain-pipes, and the inner soil body of its plastic drain-pipe need not be emptied, and therefore can not affect bulk strength and the stability of the soil body.Plastic drain-pipe has settled base, can ensure the horizontal and vertical degree of plastic drain-pipe, is not damaged by pressure crowded bad bottom protection plastic drain-pipe.Base is provided with groove, facilitates snapping in of band drain, can prevent plastic drain-pipe from rotating, and also can prevent plastic drain-pipe from upwards arching upward.Fill up the material of good water permeability in drainage channel, neither affect draining, the outside soil body can be stoped again to extrude cloth bag, occupy drainage channel space, drainage path is obstructed, affect the situation of drainage effect.。Plastic drain-pipe sidewall arranges drain hole, the discharge of plastic draining intralamellar part soil body pore water can be solved simultaneously.Compared with the plane structure of plastic draining board, plastic drain-pipe is structure spatially, and rigidity obviously increases, and substantially improves plastic draining board shape single, and bulk strength is not high, the situation of easy distortion bending.What is more important plastic drain-pipe is axially symmetric structure, as sand wick, more can cater to the dissipation law of pore water pressure, and pore water from surrounding discharged to plastic drain-pipe, can be accelerated soil solidifying speed and reach good even drainage effect.This is that plastic draining board can not be accomplished, it can only one direction draining, greatly affects drainage effect.The packed plastic water draining device of the utility model had both imitated the advantage of sand drain, turn avoid sand drainage construction complexity, problem costly.The utility model plastic water draining device both make use of the feature that the Plastic Drain Slab Construction duration is short, cost is low, avoided the drawback of plastic draining board one direction draining simultaneously.The utility model combines the advantage of sand drain and plastic draining board, has started plastic water draining device, has improve drainage effect, has the advantages such as structure is simple, cost is lower, effective simultaneously.

Detailed description of the invention

Now in conjunction with Figure of description and embodiment, technical scheme of the present utility model is described in further details.

Packed plastic water draining device of the present utility model, comprise plastic drain-pipe 1, base 2 and cloth bag 3, the outer wall of plastic drain-pipe 1 is provided with axial drainage groove 4, plastic drain-pipe 1 is provided with the drain hole 5 with drainage groove in communicating pipe, in drainage groove 4, fills up dank material 7.Plastic drain-pipe 1 can be rolled into tubulose by plastic draining board at the construction field (site), and junction seccotine is bonding, and to staple together reinforcing with large size, also directly can make shaping in factory.Base 2 is provided with the groove for being snapped in by plastic drain-pipe 1 wherein, acting as of groove prevents plastic drain-pipe 1 from rotating and arching upward.Cloth bag 3 is the long bag of permeable geotextile, and its shape is that upper opening is cylindric, and diameter is equal to plastic drain-pipe 1, and pore water is filtered in its effect, and blocks soil body particle, prevents drainage channel to be blocked.

At the construction field (site), will be stuck in the groove of base 2 bottom plastic drain-pipe 1, form an entirety.Then be from bottom to top tightly enclosed within overall outside with cloth bag 3, form whole device.In drainage groove 4, the material 7 of water permeability is filled up, as medium coarse sand etc. during construction.
