Improvement method for weakening collapsibility of loess of foundation
The invention discloses an improvement method for weakening collapsibility of foundation loess, which comprises the following steps: S1, selecting the address of yellow soil, and drying and crushing the selected yellow soil; s2, adding plant ash, limestone and metal slag into the crushed yellow soil, and uniformly mixing according to a certain proportion; s3, the evenly-mixed soil is subjected to layered backfilling, and layered tamping is conducted in the backfilling process; and S4, stone pieces are laid on the surface of the soil after layered compaction. According to the method, the loess of the weakened foundation is excavated out, the excavated loess is improved, piling is carried out in the foundation with the loess excavated out to extrude the foundation, the foundation is reinforced conveniently, then layered padding is carried out on the improved loess, impact is carried out through a heavy hammer, and the firmness of the weakened foundation is effectively guaranteed; the method can be widely applied to highway construction and high-rise building construction, foundation settlement can be effectively reduced, and the firmness of highway and building foundations is guaranteed.
本发明公开了一种减弱地基黄土湿陷性的改良方法,包括以下步骤:S1:黄土壤的地址选取,将选取的黄土壤进行干燥、粉碎处理;S2:将粉碎处理的黄土壤中添加草木灰、石灰石、金属矿渣,并按照一定比例混合均匀;S3:将混合均匀的土壤进行分层回填,在回填过程中分层夯实;S4:分层夯实后在土壤表面进行铺设石子片。本发明通过对减弱地基的黄土进行挖除,并对挖除的黄土进行改良,在挖除黄土的地基中进行打桩挤压地基,便于对地基进行加固,然后通过对改良后的黄土进行分层垫设,并通过重锤冲击,有效的保证了减弱地基的牢固性,能够广泛的运用于公路建设和高层建筑的建设,能够有效的降低地基的沉降,保证了公路和建筑地基的牢固度。
