FIELD: construction. ^ SUBSTANCE: method of barrage erection includes layerwise laying, screeding and impaction of the barrage body from no-fine rigid little concrete mixture by pours along the axis of its upper and lower parts and the device between them of against filtration element - the diaphragm at bituminous base. The barrage body from no-fine rigid little concrete mixture is artificially cooled by passing of cooling water gravitation through the pores of this concrete body. For diaphragm arranging in the body of the erected barrage the middle zone is formed between the upper and the lower parts of the barrage, at that no-fine rigid little concrete mixture is laid, screeded and dabbed levelwise and layerwise: first levelwise in the middle zone between the upper and the lower part of the barrage of appropriate width to provide in this zone automobile traffic and of appropriate thickness to provide distribution of heated bitumen through all the depth of the level in the amount of 2-4 levels that form the layer of this middle zone by jumpes in the direction of the upper and lower part of the barrage. Following the laying of such a level no-fine rigid little concrete mixture is matures till it hardens, after that to the area of the arranged diaphragm by means of a bitumen distributor previously heated bitumen is delivered and is poured just on the surface of the no-fine concrete along the axis of the barrage all along the pour in volume providing its distribution through the pores of the concrete body by gravitation till the previously laid bitumen layer hardened in the pores of the barrage body. Following the closure of the middle zone formation from the laid levels on the general depth no-fine rigid little concrete mixture is laid, scredeed and dabbed in the upper and lower parts of the barrage of the layer with the same width. ^ EFFECT: increase of reliability and efficiency of the work of against filtration element at bituminous base. ^ 6 dwg |
