Description
Technical field
The utility model relates to civil engineering drainage plant field, particularly relates to a kind of NEW TYPE OF COMPOSITE earthwork water drain net.
Background technology
Composite drainage network is ingredient important in civil engineering drainage plant.Under boreal climate condition, lay composite drainage network and can help the impact alleviating frost heave, if frost depth is very dark, drainage network can be laid on position more shallow in base, block as capillarity, often also need to use the granular subbase of not easily frost heave to replace in addition, be extended to frost depth downwards; Be laid between ground and base, for discharging ponding between ground and base, block capillary water and be effectively attached in edge drainage system, this structure shortens the draining water way of ground automatically, water discharge time shortens greatly, and the usage quantity of sill choicely can be made to reduce, the application life of road can be extended; Road is aging, after cracking initiation, major part rainwater will enter in section, in this case, under drainage network is laid immediately on road surface, replacement can draining foundation, and it can collect in advance by drainage network before moisture enters ground/subbase, but also a skim can be wrapped in the bottom of drainage network, no matter prevent moisture from entering ground further, be that this structure can both extend the application life of road to rigidity road or flexible pavement system.
Chinese Patent Application No. 200620125084.2, name is called in the patent of three-dimensional composite earthwork drainage network, proposes a kind ofly to be formed the earthwork water drain net of three-dimensional netted discharge structure to intersect superimposion mode.But the water guide layer of this three-dimensional composite earthwork drainage network is all be woven into tridimensional network.On the one hand, netted structure is comparatively complicated, extends process time, adds processing cost, also improves the cost of construction; On the other hand, the structure water guide performance of netted water guide layer intersection superposition is not good.In addition, the drainage layer of this three-dimensional composite earthwork drainage network is all directly be placed on water guide layer, and when being squeezed effect, drainage layer and water guide layer can stagger, and the impurity in water can not get filtering, and is blocked by water guide layer, thus affects drainage effect.
Utility model content
For prior art above shortcomings, the utility model proposes a kind of NEW TYPE OF COMPOSITE earthwork water drain net, it comprises middle drainage network and the overlying strata covered on drainage network and lower coating; Described drainage network cross section is rectangle, and there is drain hole drainage network, and drain hole comprises transverse row water hole and vertical drainage hole, and transverse row water hole is run through with vertical drainage hole and communicated; Described drainage network is by particular manufacturing craft single injection-molded; Described overlying strata and lower coating material are PFY acupuncture nonwoven geotextiles; Described overlying strata and lower coating are bonded on drainage network by adhesive, and its upper and lower coating intensity is high, and chemical stability is higher, free from environmental pollution, and filter eye is thin, and fine impurities can be filtered.The utility model design science is reasonable, novel structure, and drainage network compound with regular structure is easy to process, reduces construction cost, and resistance to compression, tension, anti-shear ability are strong; Drain hole is rounded, and drainage efficiency is high; Being bonded on drainage network by upper and lower coating, can not stagger because of extruding in upper and lower coating and drainage network.
The utility model solves its technical problem, and the technical scheme adopted is: a kind of NEW TYPE OF COMPOSITE earthwork water drain net, relates to civil engineering drainage plant field, comprises middle drainage network and the overlying strata covered on drainage network and lower coating; Described drainage network cross section is rectangle, and there is drain hole drainage network, and drain hole comprises transverse row water hole and vertical drainage hole, and transverse row water hole is run through with vertical drainage hole and communicated.
Further, described drainage network is by particular manufacturing craft single injection-molded.
Further, described drainage network is water guide layer.
Further, described overlying strata and lower coating material are PFY acupuncture nonwoven geotextiles.
Further, described overlying strata and lower coating are filtration beds.
Further, described overlying strata and lower coating are all bonded on drainage network by adhesive.
Further, described drain hole is rounded.
Compared with prior art, the beneficial effects of the utility model are: a kind of NEW TYPE OF COMPOSITE earthwork water drain net that the utility model proposes, has design science reasonable, novel structure, drainage network compound with regular structure, easy to process, while cutting down finished cost, also reduce construction cost; Its drain hole is rounded, and transverse row water hole is run through with vertical drainage hole and communicated, and improves drainage efficiency, and resistance to compression, tension, anti-shear ability are strong; Be bonded on drainage network by upper and lower coating, can not be staggered because of being squeezed in upper and lower coating and drainage network, drain hole can not be blocked by impurities in water; Upper and lower coating material is PFY acupuncture nonwoven geotextiles, and intensity is high, and chemical stability is higher, and long service life is free from environmental pollution, and filter eye is thin, and fine impurities can be filtered.
Accompanying drawing explanation
Fig. 1 is general structure schematic diagram of the present utility model.
Description of reference numerals: drainage network 1, overlying strata 2, lower coating 3, transverse row water hole 4, vertical drainage hole 5.
Detailed description of the invention
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the utility model further.
As shown in Figure 1, a kind of NEW TYPE OF COMPOSITE earthwork water drain net, relates to civil engineering drainage plant field, comprises middle drainage network 1 and the overlying strata 2 covered on drainage network 1 and lower coating 3; Described drainage network 1 cross section is rectangle, and there is drain hole drainage network 1, and drain hole comprises transverse row water hole 4 and vertical drainage hole 5, and transverse row water hole 4 is run through with vertical drainage hole 5 and communicated, and be convenient to the water of discharging all directions, water guide effect is good.
