Abstract
Przedmiotem wynalazku jest sposób ulepszenia podłoża gruntowego na drodze powierzchniowej lub wgłębnej stabilizacji. Sposób ulepszenia podłoża gruntowego poprzez zmieszanie gruntu z odpowiednią ilością spoiwa i wody, wałowanie oraz zagęszczenie i profilowanie charakteryzuje się tym, że po wymieszaniu gruntu z mineralnym spoiwem z aktywnych wypełniaczy hydraulicznych opartego na bazie popiołów lotnych z węgla brunatnego dozowanym wagowo w przeliczeniu na 1 m2 powierzchni z dokładnością do ± 5% oraz zagęszczeniu rozprowadza się na podłożu gruntowym spoiwo w postaci cementu w ilości 2 -3% i miesza mieszankę gruntową na mniejszą głębokość. Mineralne spoiwo w postaci popiołów lotnych aplikuje się do gruntu w ilości od 2,5 - 6% w stosunku do masy gruntu, wodę dozuje się objętościowo lub wagowo, aż do uzyskania wilgotności optymalnej, z tolerancją +10%, -20% jej wartości.The subject of the invention is a method for improving a soil substrate by surface or downhole stabilization. The method of improving the subsoil by mixing the soil with the right amount of binder and water, rolling, compaction and profiling is characterized by the fact that after mixing the soil with a mineral binder made of active hydraulic fillers based on fly ash from brown coal, dosed by weight calculated per 1 m2 of surface with an accuracy of ± 5% and compaction, the binder in the form of cement is spread in the amount of 2 -3% on the ground, and the soil mix is mixed to a smaller depth. Mineral binder in the form of fly ash is applied to the soil in an amount of 2.5 - 6% in relation to the weight of the soil, water is dosed by volume or weight, until optimal humidity is obtained, with a tolerance of + 10%, -20% of its value.
