Description
Technical field
The present invention relates to ground technical field of drainage, more particularly to a kind of drain structure of arc capillary diversion passage.
Technical background
Moisture is the key factor for influenceing Rock And Soil weak intercalated layer or the sliding layer physico-mechanical properties that comes down, in China mountain area
Phase in rainy season landslide, engineering slope is slippery etc., and geological disaster happens occasionally, reason of searching to the bottom is that phase in rainy season moisture penetrates into
Weak intercalated layer or landslide sliding layer, and penetrate into moisture and are difficult to effectively be excluded, and cause soft of soil, intensity index drastically under
Drop.
At present, friction pile is commonly used for reinforcing weak intercalated layer or landslide sliding layer, and consolidation effect is notable, but stabilizing piles
Invest it is high, be unfavorable for environmental protection；On the other hand, the common perforate drainpipe of tradition is also commonly used for weak intercalated layer or landslide sliding layer row
Water, in the hope of excluding Rock And Soil moisture, Rock And Soil intensity index is improved, hole, row are easily blocked however, its shortcoming is sand grain
The a large amount of silts of alluvial, filtering Netease are blocked etc. in water pipe, it is difficult to realize long-term drain function, geological disaster can still occur.Cause
This, active demand is a kind of to can be achieved the permanently effective drain structure for excluding Rock And Soil moisture, to improve weak intercalated layer or landslide
The Rock And Soil mechanical index such as sliding layer, reduce reinforcing engineering amount, meet environmental requirement, realize ground slopes safety and stability.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of drain structure of arc capillary diversion passage, so that rock
Soil body weak intercalated layer or landslide sliding layer realize the function of long-term draining, ensure ground slopes safety and stability.
Technical scheme used by the present invention solves above-mentioned technology is as follows：
A kind of drain structure of arc capillary diversion passage of the present invention, including drain pipe body, and along between longitudinal direction
Every the cross hang being arranged in drain pipe body, it is characterized in that：Between between the both sides inwall and outer wall of the drain pipe body
Every being provided with arc capillary diversion passage, each arc capillary diversion passage includes entrance, inner tube and outlet, and inner tube moves towards curved
Curve.
The invention has the advantages that setting arc capillary diversion passage in drain pipe body both sides, extend diversion passage,
Avoid soil particle from entering in drainpipe to result in blockage, permanently effective can exclude full water or non-full water ground internal water, improve soft
The Rock And Soil mechanical strength index such as weak interlayer or landslide sliding layer, the function of long-term draining is achieved, ensures ground slopes peace
It is complete stable, avoid geological disaster；The drain structure development of ground field is promoted, with structure is novel, function is reliable, section
About investment, construction is simple, meet the features such as environmental protection.
The present invention is applied to landslide, Landslide, weak intercalated layer, barricade banket, the diversion draining of water seepage mechanism.

The drainpipe 10 of arc capillary diversion passage, ordinary draining pipe 20.
Embodiment
The present invention is further illustrated below by specific embodiment and with reference to accompanying drawing.
Reference picture 1, a kind of drain structure of arc capillary diversion passage of the invention, including drain pipe body 1, and
The longitudinally spaced cross hang 3 being arranged in drain pipe body 1.Between the both sides inwall and outer wall of the drain pipe body 1
Arc capillary diversion passage 2 is arranged at intervals with, each arc capillary diversion passage 2 includes entrance 2.1, inner tube 2.2 and outlet 2.3,
Inner tube 2.2 moves towards curved curve.
Reference picture 1,2.2 a diameter of 0.2~0.4mm of said inner tube, the outlet 2.3 and the discrepancy in elevation of entrance 2.1 are less than
0.5a, a are the fluid column lifting height of arc capillary diversion passage 2.The entrance 2.1 the outer wall of drain pipe body 1 by rectangle or
Quincuncial arrangement, the elevation of the outlet 2.3 is bigger than the inwall Bottom Altitude of drain pipe body 1, outlet 2.3 and drain pipe body 1
The discrepancy in elevation of inwall bottom is not less than 10mm.
Reference picture 1, the cross hang 3 include acting on the vertical supporting 3.1 and cross-brace of the inwall of drain pipe body 1
3.2, the spacing longitudinally disposed in drain pipe body 1 of cross hang 3 is not more than 0.5m.The drain pipe body 1 is inclined when burying
Oblique drainage grade is not less than 2%.
Embodiment：
Reference picture 2, a certain mountain area slopes include covering rock mass 30, weak intercalated layer 40, Rock 50 successively from top to bottom；Cover
The poor permeability of rimrock body 30 and Rock 50, Infiltration are difficult；But rainwater can penetrate into weak intercalated layer 40, and moisture easily causes soft
The physical mechanics intensity index of weak interlayer 40 reduces.Below using the drain structure of arc capillary diversion passage to the mountain area slopes
Weak intercalated layer 40 is carried out to carry out drawing Drainage Design.
Reference picture 2 and Fig. 3, in incline direction, if weak intercalated layer 40 is positioned over rock mass 30 and Rock 50, ejectment water is set
Meter combination is using the drainpipe 10 of arc capillary diversion passage and the draining of ordinary draining pipe 20, wherein arc capillary diversion passage
Pipe 10 is arranged in weak intercalated layer 40, and ordinary draining pipe 20 is arranged in covering rock mass 30.The draining of arc capillary diversion passage
