Compaction soil-cement-fly ash pile
The invention discloses a compaction soil-cement-fly ash pile which is used for a subgrade of a building and a road. The compaction soil-cement-fly ash pile comprises, in volume, cement 12.5%, fly ash 7.5% to 37.5% and soil 50% to 80%. The preparation method comprises: A, digging a pile hole; B, sieving the soil digging out during digging the pile hole, mixing the sieved soil, cement, fly ash and water proportionally; C, performing test compaction before full scale construction to determine the padding quantity of every ramming and the ramming intensity; and D, performing the pile body construction. The compaction soil-cement-fly ash pile adds a certain amount of fly ash in preparation process, so that the intensity and bearing capability of the soil pile are improved, the range of application of the fly ash is enlarged. Moreover, the compaction soil-cement-fly ash pile is clean and environmental friendly.
