щую обрушение мерзлого грунта при проходе поезда, например на рассто ние 10-20 см от реборд спирали шнековой колонны. После этого замеп ют замораживающие колонки на нагреватели и оттаивают ими ранее замороженный грунт на толщину, достаточную дл извлечени шнековой колонны из скважины, например на 2-3 см от тех же реборд и в пространстве между витками спирали шнековой колонны. Скважину очищают от сплывших в нее талых грунтов путем врашени шнековой колонны. Извлекают шнековую колонну из скважины. В скважине устанавливают в проектно .е положение водозаборный фильтр с трубой дл отвода дренируемой воды за пределы земл ного полотна.The penetration of frozen soil during the passage of a train, for example, at a distance of 10-20 cm from the flanges of the spiral auger column. After that, the freezing columns are placed on the heaters and they thaw out the previously frozen soil by a thickness sufficient to extract the auger column from the well, for example, 2-3 cm from the same ribs and in the space between the turns of the auger column. The well is cleaned from thawed soils that have melted into it by vrashen auger column. Remove the auger column from the well. In the well, a water intake filter with a pipe for draining the drained water beyond the bed is installed in the design position.

Гидроизол ционным материалом тампонируют пространство между водоотводпой трубой фильтра и стенками скважины.Waterproofing materials tampon the space between the drainage pipe of the filter and the walls of the well.

Использование предлагаемого способа установки водозаборного фильтра поперечного трубчатого дренажа в плывунных грунтах же .лезнодорожного земл ного полотна дает возможность надежной установки водозаборного фильтра в его проектное положение с производством этих работ без ограничени скорости движени поездов и с обеспечением условий полной безопасности их движени .Using the proposed method of installing a transverse tubular drainage intake filter in the floating ground of the same railroad bed allows reliable installation of the intake filter in its design position with the production of these works without limiting the speed of trains and ensuring complete safety of their movement.

Invention Formula

A method for installing a water intake filter of transverse tubular drainage in flowing soil of railroad ground soil, which consists in drilling a borehole with a hollow auger column, characterized in that, in order to safely install the drain water intake filter in its design position with the production of these works without speed limitation movement of trains and with ensuring the conditions of full safety of their movement, a hollow auger column is not removed from the well, freezing columns are installed inside it, freeze Runt the thickness excluding soil collapse during the passage of rolling stock, the freeze substitution derivatives m columns on heaters previously frozen and thawed soil at

the thickness sufficient to extract the column from the well, rotating the auger column, clean the well from the thawed soils that had been poured into it, remove the hollow screw auger column from the well, and then install a water intake filter in the well, and well walls.
