Abstract

Изобретение откоситс  к устройствам дл  динамического уплотнени  грунтов и позволит повысить эффективность уплотнени . Рабочий орган дл  динамического уплотнени  грунтов содержит ударную часть 1 с центральным отверстием 2, ударную часть 3, размещенную в отверстии 2 и соединенную с частью 1 с возможностью подъема над ней, захватное приспособление 4„ закрепленное на ударной части 3. Отношение масс ударной части 3 к части 1 составл ет 1:(1...1,5). Отношение площадей оснований 9 и 8, ударной части 3 к части 1 составл ет 1:(1,5...3,0).2ил.The invention relates to devices for dynamic compaction of soils and will improve compaction efficiency. The working body for dynamic soil compaction contains a shock part 1 with a central hole 2, a shock part 3, located in the hole 2 and connected to the part 1 with the possibility of lifting above it, a gripping device 4 fixed on the shock part 3. The mass ratio of the shock part 3 to part 1 is 1: (1 ... 1.5). The ratio of the areas of the bases 9 and 8, of the impact part 3 to part 1 is 1: (1.5 ... 3.0). 2 yl.
