Description
Technical field
The invention belongs to the highway engineering technical field, relate in particular to and a kind ofly be applicable to that underpass type after Expressway Embankment reduces is by the water discharge method on dealings road---utilize the method for comprehensively discharging accumulated water of underpass roads by filtering infiltration pond.
Background technology
For reducing the express highway roadbed depth of fill, guarantee that simultaneously ground rainwater that underpass type compiled by the dealings road can in time get rid of when big, do not influence by the normal of dealings road under general rainfall intensity and pass through, water discharge method commonly used mainly contains awning draining, evaporation basin draining and methods such as seepage pit or sewer draining.Wherein the major defect of awning draining is that employed waterproofing materials is aging easily, cost height when area is big, and the replacing and the maintenance cost of awning are bigger, and this mode causes underway ponding easily; The major defect of evaporation basin draining is that occupation of land is more, and cost is corresponding bigger than normal, and can't satisfy drainage requirement when raining in torrents, and also causes underway ponding easily; Though and seepage pit or sewer drainage pattern road pavement runoff have certain damming and the diafiltration catharsis, but when the underway catchment area was big, draining was slower, when especially running into rainstorm weather, the easy ponding of underway also might produce pollution to surrounding enviroment and underground water.
Summary of the invention
The technical problem to be solved in the present invention is, deficiency at the prior art existence, a kind of method of comprehensively discharging accumulated water of underpass roads by filtering infiltration pond is provided, use this method when groundwater table lower (deeply), underway charge for remittance amount are big, can make underway surface flow rainwater through compiling and after decontamination handles, can not only be penetrated into the shallow-layer permeable ground by osmotic cell, can be penetrated into deep layer underground water-permeable soil layer by the infiltration well simultaneously, and recharge groundwater, thereby obtain good social economy and environmental benefit.
Solution of the present invention is that the method for described comprehensively discharging accumulated water of underpass roads by filtering infiltration pond with reference to Fig. 1, is to be divided into a collecting well 4 at road main line 1 and underpass type by the cross way both sides gutter 3 on dealings road 2 or covered conduit.Establish an osmotic cell 6 in the permeable ground on the collecting well 4 side groundwater table.Establishing an infiltration well 10 in this osmotic cell 6 is passed down through at the bottom of the pond.Inlet one end cap that infiltration well 10 protrudes upward at the bottom of the pond is put a screen pack 8.Cloth hole on the part borehole wall of infiltration well 10 at the bottom of protruding upward the pond, hole area are not less than described infiltration well 10 and protrude upward 30% of part borehole wall area at the bottom of the pond.Screen pack 8 tops cover one deck filtration beds 7, and the infiltration well 10 well body peripheries of screen pack 8 belows also are one deck filtration beds 7 at the bottom of the pond of above-mentioned osmotic cell 6 also around one deck filtration beds 7.The lower end well body periphery that infiltration well 10 passes at the bottom of the pond is filled one deck sandstone 9.Infiltration termination, well 10 lower end periphery is downwards water barrier 12 and permeable ground 13 successively.Infiltration well 10 passes water barrier 12 and stretches to permeable ground 13, infiltration well 10 passes cloth hole on the borehole wall of one section well body that water barrier 12 stretches to permeable ground 13, hole area also be not less than described infiltration well 10 pass one section well body under the water barrier 12 borehole wall area 30%, fill one deck roof clay ball layer 11 at water proof interval well body periphery.Pass on the borehole wall of one section well body under the water barrier 12 around one deck sand net 14 at infiltration well 10.Use a gutter 5 pipes to lead to and connect described collecting well 4 and described osmotic cell 6, utilize the vermiculite filtration beds 7 in the described osmotic cell 6 and the sieving function of screen pack 8, remove suspension in above-mentioned gutter 3 or covered conduit and the osmotic cell, ammonia nitrogen, heavy metal ion one pollutant and obtain comprehensively to permeate discharge through the rainwater of purified treatment.
When the method for comprehensively discharging accumulated water of underpass roads by filtering infiltration pond of the present invention comes into operation, its collecting well 4 places trackside gutter 3 or covered conduit below, osmotic cell 6 bottoms place the permeable ground on the groundwater table, connect with gutter 5 pipes between the two, can make the long-pending underway surface flow rainwater of gutter 3 or covered conduit institute flow into collecting well 4, flow into osmotic cell 6 through gutter 5 then, filtration beds in osmotic cell 67 filters layer by layer with screen pack 8 again, infiltrates the shallow-layer permeable ground by the osmotic cell bottom behind the pollutant in the elimination pavement runoff, discharge the rainwater of the above-mentioned purified treatment of process simultaneously with penetration mode to the deep layer permeable ground by infiltration well 10.
The invention has the beneficial effects as follows, because the method for this comprehensively discharging accumulated water of underpass roads by filtering infiltration pond is proved to be reasonable in design through practice test, be provided with simple, after underway surface flow rainwater is compiled, handle through decontamination, when groundwater table lower (deeply), be penetrated into shallow-layer permeable ground and deep layer underground water-permeable soil layer by osmotic cell and infiltration well simultaneously, get rid of fast and eliminate pollutant in the rainwater, and additional underground water, thus in highway engineering construction very easy applying.That this method has is effective, instant effect, less investment, environmental protection, economic characteristics, can obtain good social economy and environmental benefit.
