Hydromechanical Method of Soil Compaction

One of the effective methods for improving the physical and mechanical properties of soils of the foundations of structures is their compaction. The correct implementation of the compaction process significantly increases the bearing capacity of the foundation, evenly distributes the loads from the structures to the foundation, ensuring the stability of the upper and lower prisms of soil dams, reduces water seepage through the body of dams, increases the likelihood of maintaining the structure of compacted soils under the action of dynamic and seismic loads. For soil compaction, static, dynamic, and vibrational methods are used. These methods have a great effect when soil moisture is reached to range within 16 to 18%. Basically, various roller designs are used in soil compaction of earth structures. A review of existing soil compaction machines is given. The disadvantages of the existing soil compaction machines are their massiveness (roller mass up to 40t), the number of passes in one place (three or four), high consumption when watering the soil surface, and waiting for dry-up after watering each soil layer. The article recommends new designs of soil compaction, which eliminates the disadvantages of existing machines, namely: roller is reduced by 50-60%, water consumption is reduced two times, and the number of passes is reduced to one pass.
