Description
Вытрамбовывание котлована под фундамент в песчаном или супесчаном грунте 1 производ т следующим образом.Punching out the foundation pit in sandy or sandy loam soil 1 is performed as follows.
На поверхности грунта 2 отсыпают слой глинистого грунта 3 с влажностью близкой к оптимальной и щебн 4, либо другого крупно зернистого материала (грави , песчано-гравийной смеси, крупного песка), трамбовкой 5 вытрамбовывают котлован 6. В процессе вытрамбовывани котлована щебень погружаетс в глинистый слой, щебенисто-глинистый слой выт гиваетс вдоль стенок и создает щебенисто-глинистую оболочку 7, предотвращающую обрушени стенок котлована. После вытрамбовывани котлована на глубину 1,5-ЗА (h - суммарна толщина щебенисто-глинистого сло ) в котлован 6 отсыпают поэтапно следующий слой глинистого грунта 3 и щебн 4 и производ т через них дальнейшее вытрамбовывание котлована 7 на заданную глубину Я.A layer of clayey soil 3 is filled with soil near the optimum and crushed stone 4, or another coarsely grained material (gravel, sand and gravel, coarse sand), tamping 5 extrudes the soil 6. The rubble-clay layer stretches along the walls and creates a rubble-clay shell 7, which prevents the walls of the excavation from collapsing. After the excavation of the excavation to a depth of 1.5-WA (h is the total thickness of the rubble-clay layer), the next excavation of the clay soil 3 and crushed rock 4 is gradually poured into the excavation 6 and the subsequent excavation of the excavation 7 is performed through them
При реализации описанного способа возведени фундамента- обеспечиваетс возможность вытрамбовывани котлована в песчаных и супесчаных грунтах. По сравнению с изготовлением фундамента в отрываемом котловане обеспечиваетс снижение объема земл ных работ в 2-3 раза за счет исключени обратной засыпки котлована; полное исключение опалубочных работ при бетонировании фундаментов «враспор со стенками вытрамбованного котлована; повышение несущей способности фундамента за счет шлотнени грунта под и вокруг котлована; снижение стоимости и трудоемкости изготовлени фундамента в 1,5-2 раза.When implementing the described method of erecting a foundation, it is possible to wipe out a pit in sandy and sandy sandy soils. Compared with the manufacture of the foundation in a trench, which is torn off, the volume of earthworks is reduced by a factor of 2-3 by eliminating the backfilling of the excavation; complete elimination of formwork work during the concreting of foundations “with the walls of the compacted pit; increasing the bearing capacity of the foundation due to soil compaction under and around the pit; reducing the cost and complexity of manufacturing the foundation by 1.5-2 times.
