Description

Изобретение относитс к дорожному строительству .и может быть использовано , в основном, в северных райо нах с продолжительным зимним сезоном .The invention relates to road construction .and can be used mainly in northern regions with a long winter season.

Известен способ возведени зимних дорог с лед ным покрытием/ включающий уплотнение и планировку основани , естественного промораживани поверхностного сло грунта/ выполнение в грунте поперечных траншей с вентил ционными коробами ипослойное намораживание льда путем поливки основани водой 1.There is a method of erecting ice-covered winter roads / involving the compaction and lay-out of the base, natural freezing of the surface layer of the soil / making transverse trenches in the soil with ventilation ducts and layer-freezing of ice by watering the base with water.

Недостатком такого способа вл етс его значительна трудоемкость.The disadvantage of this method is its considerable complexity.

Наиболее близким к изобретению техническим решением вл етс способ возведени дорог, включающий подготовку земл ного полотна, выдерживание его в естественных услови х ЛО промерзани с последующим наращиванием на его поверхности сло льда С 21.The closest technical solution to the invention is a method of building roads, which includes preparing the earth bed, keeping it in natural conditions of LO freezing and then building up a layer of C 21 ice on its surface.

Однако дорога, построенна сог .ласно известному способу имеет сокращенный срок эксплуатации.However, the road constructed according to a well-known method has a reduced service life.

Цель изобретени - повышение срока службы дороги.The purpose of the invention is to increase the service life of the road.

Поставленна цель достигаетс тем, что согласно способу возведени зимних дорог с лед ным покрытием, включающему подготовку земл ного полотна, вьщерживание его.в естественных услови х до промерзани с последующим наращиванием на его поверхности сло льда поливкой водой, перед поливкой земл ного полотна по всей его ширине в направлении параллельнс оси дороги, выполн ют прорези.The goal is achieved by the fact that, according to the method of erecting winter roads with ice cover, which includes preparing the earth bed, holding it under natural conditions until it freezes and then builds up on its surface an ice layer by watering it with water width in the direction parallel to the axis of the road, slots are made.

При этом прорези могут быть выполнены с помс цью дискового катка.In this case, the slits can be made with a disk roller.

на чертеже изображено дорожное основание, возведенное согласно предлагаемому способу, поперечный разрез.the drawing shows the road base, erected according to the proposed method, the cross-section.

Летом приступают к подготовке основани дорожного полотна 1, вы20 корчевывают пни и удал ют кустарник и мелколесье. Удал ют растительный слой на всю ширину земл ного полотна. Дл работ используют бульдозе- , ры с рыхлительньал оборудованием и In the summer, they start preparing the base of the roadbed 1, stump up stumps and remove shrubs and undergrowth. The vegetation layer is removed over the entire width of the gravel. For work using bulldozers, ryhlival equipment and

25 корчеватели, осуществл ют планиров-ку поверхности дорожного полотна.25 uproaders, plan the surface of the roadway.

Claims

With the onset of the first frosts in wet areas and shallow marshes, a trajectory was made. One30 temporarily or after the earth is fixed in the latter, in the latter along its entire width, at a certain distance from each other, longitudinal slots are grooved

2. For this work, for example, trailed disk rollers can be used. Then, the roadbed is retained in natural conditions until it is washed out. The first watering of the roadway with water is carried out with sufficient freezing of the upper soil layer. If the road has snowed, a layer up to 5 cm can be watered without compaction, and with thicker layers of snow, it is removed by snow removal equipment. During watering the roadway water Fills longitudinal cuttings 2f and further watering the road in winter up to the optimum ice coating thickness of 25–30 cm. The ice coating 3 in cross section due to the cut-grooves 2 gets a comb shape, and the ground canvas is as if reinforced with longitudinal ice threads. The stability of the road increases significantly due to the fact that the ice in the grooves during the spring period does not melt much longer and, moreover, the overall increased thickness of the ice cover also causes an extension of the duration of the winter roads. Thus, the proposed method does not require special construction materials, is simple to implement and increases the lifespan of the road, Formula 1, A method for constructing ice-covered winter roads, including the preparation of a landbed, VEV keeping it in natural conditions until freezing and subsequent buildup on the surface of the ice layer, watering with WATER, characterized in that, in order to increase the life of the road, before watering the earth bed with water across its entire width in a direction parallel to and roads vptoln dissolved slot. 2, Method pop, 1, characterized in that the slits are made using a disk roller.
