Description
Изобретение относитс к горному делу и может использоватьс дл проветривани горных выработок. Известна гибка вентил ционна труба, включающа соединительные звень и ребра жесткости, выполненные в виде карманов , в которые помещаетс стальна проволока . Однако известную вентил ционную трубу трудно извлекать дл повторного исполь зовани . Цель изобретени - обеспечить возможность извлечени вентил ционной трубы дл повторного использовани . Это достигаетс тем, что карманы пред лагаемой трубы заполнены сжатым воздухо На фиг. 1 изображена труба с пневмати ческими камерами, разрез; на фиг. 2 - то же, в разрезе с карманами, образованными внутренним и наружным сло ми. Вентил ционна труба (см. фиг. 1) состоит из рукава 1, на который через определенные промежутки пришиты или приклеены кольцевые карманы 2, в которые вкладываютс пневматические камеры 3. С обеих сторон труба снабжена соединительными звень ми 4, На фиг. 1 изображена гибка труба, состо ща из внутреннего 5 и внешнего 6 слоев материала. Оба сло , через определенные промежутки склеиваютс или свариваютс кольцевыми швами. Образовавшиес при этом карманы заполн ютс сжатым воздухом. Гибкий трубопровод работает следующим образом. Отдельные звень труб соедин ютс и карманы или пневматические камеры наполн ютс .сжатым воз.цухом. При сн тии труб сжатый воздух выпускаетс и вентил ционна труба может свободно извлекатьс из пережимов, в которые она попадает при увеличивщемс горном давлении, т.е. в местах сопр жени подготовительных выработок с очистными.The invention relates to mining and can be used to ventilate mine workings. A flexible ventilation pipe is known, which includes connecting links and stiffeners made in the form of pockets in which steel wire is placed. However, the known vent pipe is difficult to remove for reuse. The purpose of the invention is to provide the possibility of removing the vent pipe for reuse. This is achieved in that the pockets of the pipe being pre-filled are filled with compressed air. In FIG. 1 shows a tube with pneumatic chambers, a slit; in fig. 2 is the same in section with pockets formed by the inner and outer layers. The ventilation pipe (see Fig. 1) consists of a sleeve 1 on which annular pockets 2 are sewn or glued at certain intervals, into which the pneumatic chambers 3 are inserted. On both sides the pipe is provided with connecting links 4. Figure 1 shows a flexible pipe consisting of an inner 5 and outer 6 layers of material. Both layers, at certain intervals, are glued together or welded by circumferential seams. The pockets thus formed are filled with compressed air. The flexible pipe works as follows. The individual links of the pipes are connected and the pockets or pneumatic chambers are filled with compressed air. When the pipes are removed, the compressed air is exhausted and the ventilation pipe can be easily removed from the clamps into which it falls with increasing mountain pressure, i.e. in places of interface of preparatory workings with clearing.
