From experience of preparation bases under clay soils of motorways and buildings with lime pilling

Abstract

Techniques of bases improvement with weak water-saturated clay soils by compaction with the help of lime with the purpose of formation their necessary building properties piles are considered. Positive examples of lime piles use in industrial and transport construction are given. Different techniques at the stages of work on the construction of piles and formation of compacted soil bases (the combination of soil compaction with lime piles with the further arrangement of additional embankments and compaction with heavy ramming) allow to provide construction on soils hardened in this way with a limitation of the permissible deformations of the structures erected on them. The most acceptable for technological and economic reasons are the types of air lime used for the installation of lime piles. The presented characteristics of the lime of regional producers of the Odessa region allow on the basis of a feasibility study to choose a more optimal version of the lime supplier for the device of lime piles on an industrial scale. According to the presented data, the most high-quality products are produced at the Kodyma factory of building materials. To obtain the required quality characteristics of other regional producers, additional purification of raw materials from impurities is required.
