Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.According to following
Illustrating and claims, advantage of the present utility model and feature will be apparent from.Below will be by cited real
Execute example and combine accompanying drawing, describe technology contents of the present utility model and feature in detail.Need to additionally illustrate, attached
Figure all uses the form simplified very much and all uses non-ratio accurately, only in order to facilitate, to assist lucidly
The purpose of bright this utility model embodiment.For sake of convenience, described below " on ", D score and accompanying drawing
Upper and lower direction consistent, but this can not become the restriction of technical solutions of the utility model.
In conjunction with Fig. 1 to Fig. 3, present embodiment discloses a kind of drainage system for getting rid of the internal hydrops of soil,
Including gutter 1, some blind pipes 2 and some french drains 3, described some blind pipes 2 are respectively connected to for getting rid of
The gutter 1 of rainwash or storm sewer, large area place is divided into some by described some blind pipes 2
Long and narrow plot, under described french drain 3 is separately positioned on single tree wood or large area bushes, described french drain divides
Do not access blind pipe 2 nearby.Described blind pipe 2 uses dual-wall hard PVC wavy perforated pipe, i.e. U-PVC is (hard
Polrvinyl chloride) double-wall corrugated perforated pipe, tube wall uniformly beats some permeable holes.Described french drain 3 is by broken
Stone adds geotextiles composition.Water within soil enters french drain 3 or blind pipe 2, and then through gutter 1 or rain
Waterpipe enters river course nearby or city planting ductwork, thus effectively gets rid of the internal hydrops of soil, is beneficial to plant
The continued propagation of root system.
Double-wall corrugated pipe compares with single-wall corrugated pipe, and its working strength and rigidity are higher than single-wall corrugated pipe,
Being smooth due to its inner tubal wall again, so conveying liquid resistance is little, conveying sewage does not haves yet
Impurity or sedimentation of suspension phenomenon.And using the double-wall corrugated perforated pipe of U-PVC so that blind pipe 2 has
Good chemical stability, and there is good plasticity, solderability and certain mechanical strength, and shaping side
Just, density is little, light weight, about steel weight 1/5.
Described blind pipe 2 is on the basis of french drain 3, has added U-PVC (PVC-U) in metalling 5
Double-wall corrugated perforated pipe.The drainage speed of blind pipe 2 is very fast.Draining main line is due to distance, and drainage area is big,
Require that drainage measure drainage speed is fast, can promptly hydrops be entered gutter 1 or storm sewer nearby,
Therefore, in the present embodiment, draining main line uses blind pipe 2.Draining branch line (uses french drain 3) in the present embodiment
Being mainly used for trees draining, trees skewness, distance and the direction of receiving draining main line are the most indefinite.
If draining main line selects french drain 3, branch line selects blind pipe 2, and branch line drainage speed is very fast, but converges and arrive
On main line, speed will be slack-off, is unfavorable for the discharge of underground hydrops.If draining main line and branch line are all selected blind
Pipe, though the drainage speed of can ensure that, but due on trees skewness, the blind pipe on main line and branch line
Blind pipe need to hold multiplex roles successfully when connect, the blind pipe on draining main line is destroyed bigger.So it is comprehensive
Considering, draining branch line selects french drain, and draining main line uses blind pipe, and blind pipe connects with french drain, it is only necessary to by blind
Metalling in ditch communicates with the metalling in blind pipe.
Blind pipe 2 is arranged according to Greening Design figure, it is considered to the ability that root system of plant is water-fast, selectively at tap drain
The plot of segmentation is arranged.French drain 3 draining accesses blind pipe 2, and blind pipe 2 all accesses the draining of periphery design
Ditch 1 or storm sewer, be ultimately discharged into river course nearby or city planting ductwork.Situations below divides situation to process:
A. it is more than the place of 0.03 in the gradient, owing to rainwash is big, french drain 3 typically need not be set.According to
Site contour present situation and plant cultivating situation, soil improvement 40cm at lawn, improve 60cm at shrub, tall
120cm is improved at Mu.There are the most water-fast wet trees for local, drinking-water pipe can be added in plant pit
De=50mm.
B. in sparse woods meadow, trees are few, for ensureing that draining is it is contemplated that entirely do french drain 3.
C. french drain 3 is set in depression and plant gently.
D. in gently thick forest, to from blind pipe 2 apart from away from tree and the most water-fast wet plant french drain 3 is set,
The plant in remaining place is dealed with on the merits of each case, and typically can not set french drain 3, in order to avoid workload is too big, connects in blind pipe 2
Mouth is too many.
Preferably, at the present embodiment in the drainage system getting rid of the internal hydrops of soil, adjacent blind pipe 2
Between be spaced 15-20 rice, large area place is divided into some long and narrow plot.
For the ease of discharge rainwater, at the present embodiment in the drainage system getting rid of the internal hydrops of soil,
Described gutter 1 or storm sewer access catch-basin.
In order to discharge the hydrops in soil quickly and efficiently, it is preferred that Fig. 2 please be referred to, in this reality by emphasis
Execute example in the drainage system getting rid of the internal hydrops of soil, described blind pipe 2 is layed in Φ 20-30 millimeter
The first blotter 4 in, the metalling being arranged over Φ 50-60 millimeter of described first blotter 4
5, outside described first blotter 4 and the entirety of described metalling 5 and described first blotter 4
And it is respectively equipped with permeable geotextiles 6 between described metalling 5.
In order to preferably protect described blind pipe 2, in the present embodiment, described first blotter 4 is with described
