Description

Изобретение относится к машинам для уплотнения материалов, преимущественно грунтов и бетонных смесей, и направлено на повышение эффектив- ₄ности работы данных машин. $The invention relates to machines for compacting materials, primarily soil and concrete mixes, and is directed to increase the efficiency of papers, ₄ of these machines. $

Наиболее близким из известных является устройство для уплотнения грунта, содержащее приводной вал и траверсу, на концах которой симметрично смонтированы уплотняющие рабочие ю органы в виде конических элементов, обращенных вершинами друг к другу, с взаимно перпендикулярными осями вращения £1].The closest known device is a soil compaction device containing a drive shaft and a beam, at the ends of which the sealing working elements are symmetrically mounted in the form of conical elements facing each other with their vertices with mutually perpendicular rotation axes £ 1].

Недостатком известного устройства 15 является невысокая эффективность послойного уплотнения грунта, так как при послойном уплотнении данным рабочим органом грунта в глубоких колодцах и пазухах при обратной засып- 20 ке величина производительности снижается гиперболически в зависимости от глубины колодца. В то же время под2 сыпка материала сверху непосредственно на конические элементы приводит к зависанию материала на траверсе устройства и выдавливанию материала из зоны уплотнения, что существенно снижает качество и повышает энергоемкость уплотнения.A disadvantage of the known device 15 is the low efficiency of layer-by-layer soil compaction, since when layer-by-layer compaction by this working body of soil in deep wells and sinuses with backfill, the productivity value decreases hyperbolic depending on the depth of the well. At the same time, adding material from above directly onto the conical elements from above causes the material to hang on the device traverse and squeeze the material out of the sealing zone, which significantly reduces the quality and increases the energy consumption of the seal.
