Abstract

FIELD: civil engineering. SUBSTANCE: device for freezing soil includes soil and air heat exchangers and connecting heat conduit provided with condensate line. The latter is made in the form of a cord of hygroscopic filtering material. One end of the cord is open to condensate collector. Another end of the cord is open to disperser made in the form of cloth. As this takes place the disperser is equipped with a tray and connected to device body so as be relatively moved in axial direction. EFFECT: higher efficiency in operation. 1 dwg

Использование: в строительстве при термомелиорации грунтов основания фундаментов сооружений, возводимых в районах распространения вечной мерзлоты. Сущность изобретения: в известном устройстве для замораживания грунта, включающем грунтовый и воздушный теплообменники и соединительный теплопровод, снабженный конденсатопроводом, последний выполнен в виде шнура из гигроскопического фильтрующего материала, сообщающегося одним концом с конденсатосборником, а другим с рассеивателем, которые выполнены в виде сетки, причем последний снабжен поддоном и соединен с корпусом устройства с возможностью относительного осевого перемещения. Указанные особенности конструкции устройства значительно повышают эффективность его работы за счет устранения тепловых потерь и предотвращения рассеивания теплового потока, а также осуществления возможности избирательной локальной термомелиорации грунта по глубине залегания. Оно может быть эффективно использовано при возведении различных сооружений в северных районах с сохранением природного состояния вечномерзлых грунтов.Usage: in the construction during thermal reclamation of soils, the foundations of the foundations of structures erected in areas of permafrost distribution. The inventive device for freezing soil, including soil and air heat exchangers and a connecting heat conduit equipped with a condensate conduit, the latter is made in the form of a cord of hygroscopic filter material communicating at one end with a condensate collector and the other with a diffuser, which are made in the form of a grid, and the latter is equipped with a pallet and connected to the device body with the possibility of relative axial movement. The indicated design features of the device significantly increase its efficiency by eliminating heat losses and preventing heat flux dispersion, as well as by making it possible to selectively local soil amelioration along the depth. It can be effectively used in the construction of various structures in the northern regions with the preservation of the natural state of permafrost soils.
