Сущность изобретени : в поверхностный слой закрепл емого грунта внос т водный раствор поливинилового спирта с последующим обезвоживанием полимерсо- держащего сло замораживанием. 1 ил.Usage: in environmental protection. SUMMARY OF THE INVENTION: An aqueous solution of polyvinyl alcohol is added to the surface layer of a fixed soil, followed by dehydration of the polymer-containing layer by freezing. 1 ill.
Description
Изобретение относитс к строительству и охране окружающей среды, в частности к способам борьбы с ветровой и водной эрозией почв и грунтов, а также к укреплению грунтов земл ных сооружений в северных област х.The invention relates to the construction and protection of the environment, in particular to methods for combating wind and water erosion of soils and soils, as well as to the strengthening of soils of earthworks in the northern regions.
На чертеже представлена зависимость скорость эрозии различных грунтов от концентрации поливинилового спирта в паровом растворе.The drawing shows the dependence of the erosion rate of various soils on the concentration of polyvinyl alcohol in the vapor solution.
На чертеже даны следующие обозначени : 1 - песок среднезернистый, алювиальФормула изобретени The following notation is given in the drawing: 1 - medium-grained sand, aluvial
Способ создани профилактического покрыти против ветровой и водной эрозии грунтов, включающий приготовление водного раствора поливинилового спирта, внесение его в поверхностный слой грунта иA method of creating a preventive coating against wind and water erosion of soils, comprising preparing an aqueous solution of polyvinyl alcohol, introducing it into the surface layer of the soil and

Пример. Готов т 0,1-8%-ный водный раствор поливинилового спирта растворением гранулированного полимера в воде при 65-100°С. Приготовленный раствор внос т на поверхность укрепл емого грунта , перемешивают верхний слой грунта, а затем утрамбовывают. Далее производ т замораживание всего объема полимерсо- держащего грунта в течение 2-10 сут. ,Example. A 0.1-8% aqueous solution of polyvinyl alcohol is prepared by dissolving the granular polymer in water at 65-100 ° C. The prepared solution is applied to the surface of the soil to be strengthened, the topsoil is mixed, and then tamped. Next, freeze the entire volume of polymer-containing soil for 2-10 days. ,
обезвоживание полимерсодержащего сло , отличающийс тем, что, с целью расширени области применени способа и обеспечени возможности использовани его во влажных климатических зонах, обезвоживание полимерсодержащего сло осуществл ют за счет его замораживани .dehydration of the polymer-containing layer, characterized in that, in order to expand the scope of the method and to enable its use in humid climatic zones, dehydration of the polymer-containing layer is carried out by freezing it.
