Description
Technical field
The utility model relates to a kind of cold district's road salivary flow ice disease control technology.The drainage system that is fit to cold district highway in winter, the control of railway salivary flow ice uses.
Background technology
Salivary flow ice is the cold living phenomenon of cold district uniqueness.Winter salivary flow ice from the hillside, roadbed side slope dumps and descends, spread to the road surface, the culvert that blocks up, escape canal, the ice dissolution in spring, because drainage channel is iced obstruction, cause melt water to wash away road, highway is blocked, and these phenomenons are to the stable of road and ancillary structure and bring very big threat, bring hidden danger to traffic safety.China northeast, the Northwest, because of the harm that frontier defense road is caused by salivary flow ice throughout the year, road gets clogged, and the conveying of army's desired substance is subjected to very big influence.
Traditional road salivary flow ice Prevention Technique has gutter, retaining ice wall, sewer, raises roadbed etc.These measures can be played the effect of control salivary flow ice to a certain extent, but run into the time of sweeping location of salivary flow ice and weather variation abnormality, and these measures just can not reach satisfied effect.Large-scale salivary flow ice is often crossed or is walked around retaining ice wall, retaining ice foot hurdle and jeopardizes road.The outlet of the time discharge pipe line of unusual weather conditions cold, culvert outlet are blocked, and underground water different places above roadbed are forced to extrude, and freeze then, approach highway.In order to ensure the unblocked of traffic, the harm that positive control salivary flow ice causes, therefore, it is significant to solving this problem of road salivary flow ice to research and develop a kind of novel and effective measure.
Summary of the invention
In order to overcome the deficiency of traditional road tunnel salivary flow ice drainage measure, the purpose of this utility model is to provide a kind of salivary flow ice multi-outlet draining ice blocking system.Guiding theory of the present utility model is: according to the rule of natural flowing water, adopting on the underground receipts gutter has a plurality of delivery ports.It all is at first to begin to freeze from the outlet of below that cold district gutter in winter freezes, if the below delivery port freezes, by poly-ice ditch being set near the delivery port and retaining ramparp dam stops.Water flows to the delivery port of top then.The rest may be inferred, and the underground latent water flow in whole winter changed and reduces gradually along with the time.Under this technological thought instructs, solve this problem of road salivary flow ice effectively
The purpose of this utility model is to realize by the following technical solutions:
A kind of road salivary flow ice multi-outlet draining ice blocking system by delivery port, is received gutter, roadbed, and retaining ramparp dam, poly-ice ditch, reinforced concrete pipe constitutes.Laying reinforced concrete pipe under the roadbed, the underground receipts gutter that passes through roadbed is buried in the groove on the natural flowing water circuit by reinforced concrete pipe, receives gutter and is provided with delivery port; The water outlet position of delivery port is above ground level, and the below of delivery port is provided with poly-ice ditch and retaining ramparp dam.
Above-mentioned receipts gutter is a flexible porous tube, the permeable geotextiles of outer wrapping, diameter 10～20cm.
The operating principle of road salivary flow ice multi-outlet draining ice blocking system is:
In time early winter, temperature is higher, and the water yield is bigger, and current are more smooth and easy, and underground water is discharged from roadbed below delivery port farthest, and along with temperature reduces, the delivery port of roadbed below distal-most end begins to freeze, and current begin to flow out near the delivery port of roadbed position down from roadbed.When entering time severe winter, temperature further reduces, and the water yield begins to reduce, and the delivery port freeze all of roadbed below can not draining.At this moment, the roadbed top begins water outlet near the delivery port of roadbed, flowing water descends along the slope, freezes, by the poly-ice ditch of its below and the dam interception of retaining ramparp, if this delivery port is also frozen, current just flow out from the delivery port of this delivery port top position, and floating ice is by the poly-ice ditch of its below and the dam interception of retaining ramparp, because this moment, discharge was little, the amount of freezing is little, can not produce security threat to roadbed.Spring is interim, and temperature gets warm again after a cold spell, ice dissolution, and next winter is interim, and system begins to repeat the above-mentioned course of work.
The beneficial effect of advantage of the present utility model and generation is:
1, receive gutter and be set to a plurality of delivery ports, make that whole drainage system whole winter can draining, reduced the pressure in the gutter, avoided because pressure is excessive, current are irregular harm of overflowing generation above roadbed.
2, receiving gutter is flexible porous tube, has and catchments and drain function, is novel drainage pipe, and the filtration of the permeable geotextiles parcel of its external application prevents that silt from stopping up gutter.
3, flexible porous tube both can have been collected the underground water of water table aquifer, water can be drained again simultaneously, and long service life, the collection drainage performance is stable; Delivery port adopts well type heat-insulating water outlet can prolong the water outlet time of single delivery port, reduces freeze injury and takes place.
4, multi-outlet draining ice blocking system has good effect to the road salivary flow ice that prevents large-scale, is particularly suitable for weather severe cold, the abundant area use of precipitation.The utility model begins to be applied in the drainage system of the control of Daxing'an Mountainrange forest highway salivary flow ice northeastward in 2004.Engineering practice shows: multi-outlet draining ice blocking system can effectively be prevented and treated salivary flow ice and take place, and ensures traffic safety.
5, drain line can be a plurality of, will receive then that gutter is staggered to compile perforation together, is convenient to collect the diving in the whole landform unit, solves the problem of this regional road salivary flow ice.

The specific embodiment
For understanding the utility model better, further specified by following embodiment, but be not qualification of the present utility model.
The multi-outlet draining ice blocking system that adopts with Daxing'an Mountainrange Rameau highway K106+146 is an example.Geographical coordinate: N50 ° 55.734 ', E120 ° 01.563 '.Height above sea level 738m.The natural terrain gradient 3.2%.
As shown in Figure 1, on natural flowing water circuit, dig a long 525m, the groove of dark 1.7m, the channel bottom distance is at underground ever-frozen ground layer 10cm～20cm; Long 8m, internal diameter 60cm, the reinforced concrete pipe 6 of wall thickness 5cm are laid by 1.7m degree of depth place under the natural surface that passes through the roadbed location; At diameter is the permeable geotextiles of flexible porous receipts gutter 2 outer wrapping of 20cm, will receive gutter 2 pipes then and be laid in the groove, and pass through roadbed section reinforced concrete pipe 6.Three delivery ports 1 respectively are set on the receipts gutter apart from roadbed center line 175m, 100m and 50m below the roadbed 3, three delivery ports 1 respectively are set on the receipts gutter 2 apart from roadbed center line 150m, 200m and 350m above the roadbed, six delivery ports 1 are set altogether; With trench backfill; Above roadbed, dig a dark 50cm apart from the position of roadbed center line 130, wide 50cm, the poly-ice ditch 5 of long 20m, following at ditch simultaneously with the earth material build of digging out high 50cm together, wide 50cm, the earth dam 4 of long 50cm, interception top floating ice.
Present embodiment is constructed in the autumn in 2004 and finished, and is through the practical proof in 3 winters, satisfactory for result.Large-scale in the past salivary flow ice has obtained effective control.
