Description
Technical field
The utility model relates to drainage plant technical field, is specifically related to a kind of highway subgrade underground drainage facility combining structure.
Background technology
Water is the Major Natural factor of harm highway.Subsoil subsidence, wash away, cave in, burst and become muddy when a thaw sets in, cement concrete pavement purt mud, come to nothing, faulting of slab ends and disconnected plate etc., all in various degree relevant with erosion surface water and groundwater, the application life on road surface has been shortened in the effect of water, therefore, the importance of subgrade drainage design becomes increasingly conspicuous.Common ground water drainage facility has gutter, covered conduit (pipe), sewer, seepage well, manhole etc.Gutter and covered conduit are higher for groundwater table, and water table aquifer buries when dark, and underground water and dewatering dam; Sewer is for reducing groundwater table or interception underground water; Seepage well is for getting rid of near the surface water or the phreatic water that affects subgrade stability of roadbed; Manhole, for maintenance and inspection sewer, also can play seepage well effect simultaneously.The consequences such as above-mentioned ground water drainage facility performance is single, exist to intersect during construction and disturb, and can not bring into play drainage simultaneously, and long-term use easily causes facility cracking, and geosynthetics is aging.
Utility model content
The utility model is exactly for above-mentioned technical problem, and a kind of highway subgrade underground drainage facility combining structure is provided, and this structure can solve above-mentioned technical problem, and each drainage is played a role simultaneously, has effectively improved drainage efficiency.
For realizing this object, the highway subgrade underground drainage facility combining structure that the utility model is designed, it is characterized in that: it comprises by polylith placed rockfill piles up the sewer surrounding mutually, polylith placed rockfill is mutually piled up to form and is supported permeable formation, in sewer, be provided with the rubble that polylith is piled up mutually, the rubble that polylith is piled up mutually forms rubble permeable formation, the french drain that the many gutters of serving as reasons in the middle part of rubble permeable formation are linked to be.
Further, the top of described support permeable formation is equipped with separation layer.
Further, in described french drain, be evenly interval with many gutters.
Further, described separation layer is clay.
Further, the end of described adjacent two gutters is enclosed with geo-grid, and geo-grid covers the gap between adjacent two gutters.
The beneficial effects of the utility model are: by sewer, and the compound action of covered conduit and gutter, the underground water of eliminating roadbed, geo-grid efficiently solves the easily problem of cracking of gutter, covered conduit, pipe trench, has avoided the differential settlement of drainage pipe.The utility model simplicity of design, construction control is convenient, takes full advantage of favorable terrain and natural stream networks.Efficiently solve the problem of soaking for a long time at the bottom of roadbed, extended the application life of highway, draw materials conveniently simultaneously, stabilized structure is reliable, has good economic benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation in cross section in the utility model;
Fig. 2 is the structural representation of longitudinal section in the utility model;
Wherein, 1-placed rockfill, 2-rubble, 3-gutter, 4-separation layer, 5-geo-grid.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done further and is described in detail:
Highway subgrade underground drainage facility combining structure as shown in Fig. 1-2, it comprises by polylith placed rockfill 1 piles up the sewer surrounding mutually, polylith placed rockfill 1 is mutually piled up to form and is supported permeable formation, in sewer, be provided with the rubble 2 that polylith is piled up mutually, the rubble 2 that polylith is piled up mutually forms rubble permeable formation, the french drain that the many gutters 3 of serving as reasons in the middle part of rubble permeable formation are linked to be.By supporting permeable formation, the compound action of rubble permeable formation and gutter 3, the underground water of discharge roadbed, reasonable in design, compactness, drainage efficiency is high.
In technique scheme, as shown in Fig. 1-2, the top of described support permeable formation is equipped with separation layer 4.Separation layer 4 has been strengthened the stability of drainage system, has further guaranteed drainage effect, and the material of separation layer 4 can adopt clay, and clay is paved, closely knit, waterproof, to guarantee sealing performance and isolation effect, draws materials conveniently, and cost is extremely low.
In technique scheme, as shown in Figure 2, be evenly interval with many gutters 3 in french drain, between adjacent two gutters 3, gap is two centimetres.Infiltration can enter by the gap between gutter in gutter, and gutter 3 is communicated with local drainage system, has further increased drainage efficiency.
In technique scheme, as shown in Figure 2, the end of described adjacent two gutters 3 is enclosed with geo-grid 5, the gap that geo-grid 5 covers between adjacent two gutters 3.Geo-grid 5, geo-grid 5 efficiently solves the problem that gutter 3 easily ftractures in gutter, covered conduit, pipe trench, has also hindered mud simultaneously, has avoided the differential settlement of gutter, and geo-grid 5 is easy for installation, with low cost,
In the utility model, first build the wall body of the placed rockfill 1 of both sides by laying bricks or stones, then lay the pipe hardcore bed at the end, after gutter 3 is installed, backfill rubble 2 wrapped row water pipes 3, when gutter 3 is installed, reserved 2cm between tube coupling, wrap up by the long geo-grid 5 of 60cm respectively at two ends, and on the rubble 2 at top, build the placed rockfill 1 that 30cm is thick by laying bricks or stones, and the clay that last backfill 30cm is thick forms separation layer 4.
When groundwater discharge hour, infiltration is permeated by rubble and placed rockfill, directly discharges roadbed scope, is connected with local drainage system, plays the effect of drainage, dewatering; When groundwater discharge is large, by damming, cut off underground water, in seepage flow mode, collect current, due to roadbed Action of Gravity Field, infiltration is discharged roadbed scope after entering in pipe by the seam between gutter 3, is connected with local drainage system.When groundwater discharge is very large, when water percolating capacity is also very large, the water yield is simultaneously by gutter 3, rubble infiltration, and placed rockfill infiltration, discharges rapidly roadbed scope, is connected with local drainage system; Now, three of this combined system kinds of drainage patterns play a role in the drainage simultaneously.The drainage effect of the discharge structure that the utility model is designed is good, easy for installation, with low cost, and practicality is good.
The above; it is only the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
