Claims (10)

1. Способ изоляции на месте подземного паропровода (20) внутри трубы (18), отличающийся тем, что включает в себя стадии образования отверстия (14) в земле, расположенного, по существу, над паропроводом (20), размещенным внутри трубы (18), просверливания отверстия (47) в трубе (18) без воздействия на паропровод (20), проведения шланга (48) вдоль длины образованного отверстия (14) так, чтобы первый конец шланга (48) проходил через просверленное отверстие (47) и до паропровода (20), прикрепление другого конца шланга к системе накачки (52,54), накачки пенопласта (60) через шланг (48) вокруг паропровода (20) с использованием системы накачки (52,54), удаления шланга (48) из отверстия (47) в трубе и из отверстия (14) в земле, и выдерживания до отверждения пенопласта до жесткого состояния и обеспечения тем самым теплоизоляции для паропровода.1. The method of isolation at the site of the underground steam pipe (20) inside the pipe (18), characterized in that it includes the stage of formation of holes (14) in the ground, located essentially above the steam pipe (20) located inside the pipe (18) drilling holes (47) in the pipe (18) without affecting the steam line (20), holding the hose (48) along the length of the formed hole (14) so that the first end of the hose (48) passes through the drilled hole (47) and to the steam line (20), attaching the other end of the hose to the pump system (52.54), pumping the foam (60) through w eng (48) around the steam line (20) using a pump system (52.54), removing the hose (48) from the hole (47) in the pipe and from the hole (14) in the ground, and holding it until the foam cures to a rigid state and ensuring thereby thermal insulation for the steam line. 2.

Способ по п. 1, отличающийся тем, что включает в себя стадии ввода пластиковой оболочки (34) в отверстие (14) и опускания бура (44,46) через пластиковую оболочку (34) до ввода шланга (48). 7. The method according to claim 1, characterized in that it includes the steps of introducing the plastic shell (34) into the hole (14) and lowering the drill (44.46) through the plastic shell (34) before introducing the hose (48). 8. Способ по п. 1, отличающийся тем, что пенопласт (60) выбирают из группы, включающей полиуретан, полиизоцианурат и модифицированный уретаном полиизоцианурат. 8. The method according to p. 1, characterized in that the foam (60) is selected from the group comprising polyurethane, polyisocyanurate and urethane-modified polyisocyanurate. 9. Устройство повторно изолированного подземного паропровода внутри трубы с кольцеобразным пространством, образованным между трубопроводом (20) и трубой (18), отличающееся тем, что внутри кольцеобразного пространства расположена отвержденная заливка (60) из пенопласта. 9. A device of a reinsulated underground steam line inside a pipe with an annular space formed between the pipeline (20) and the pipe (18), characterized in that a cured foam core (60) is located inside the annular space. 10. Устройство по п. 9, отличающееся тем, что отвержденная заливка из пенопласта образована участками существующей жесткой изоляции (62,64,66), по существу, включенными внутрь нового залитого пенопласта (60). 10. The device according to p. 9, characterized in that the cured foam filling is formed by sections of existing rigid insulation (62,64,66), essentially included inside the new filled foam (60).
