Description
Известны способы предварительного напр жени бетона облицовок путем нагнетани за облицовки цементного раствора.Methods are known for prestressing concrete linings by injecting cement mortar over linings.
По описываемому способу бетонировани облицовок напорных тоннелей раствор нагнетают в кольцевые каналы, сделанные в облицовке во врем ее бетонировани . Дл образовани кольцевых каналов до бетонировани облицовки укладывают по периметру выработки эластичные трубки, наполн емые водой или сжатым воздухом. Затем производ т бетонирование, и после отвердевани бетона выпускают из трубок воду или воздух и трубки извлекают.According to the described method of concreting lining of pressure tunnels, the solution is injected into the annular channels made in the lining during its concreting. To form annular channels, before the concreting of the cladding, elastic pipes filled with water or compressed air are laid along the perimeter of the production. Concreting is then carried out and, after the concrete has hardened, water or air is released from the tubes and the tubes are removed.
На фиг. 1 изображен продольный разрез части тоннел ; на фиг. 2 - его частичный поперечный разрез; на фиг. 3 - поперечный разрез тоннел .FIG. 1 shows a longitudinal section of a part of the tunnel; in fig. 2 is a partial cross section; in fig. 3 is a cross section of the tunnel.
Предлагаемый способ заключаетс в следующем.The proposed method is as follows.
Облицовка бетонируетс обычным способом. Затем касательно к поверхности выработки / укладывают отрезки резиновых труб 2 овального или пр моугольного очертани таким образом, чтобы оба конца каждого отрезка находились вне облицовки. Трубы 2 под дaвлeниe заполн ют водой 3 или сжатым воздухом, после чего производ т бетонировку облицовки.The lining is concreted in the usual manner. Then, tangentially to the surface of the excavation, the rubber tube sections 2 are oval or rectangular in outline so that both ends of each segment are outside the lining. The pipes 2 under pressure are filled with water 3 or compressed air, after which the lining is concreted.
После отвердени бетона 4 воду или воздух из труб выпускают. Трубы резко уменьшаютс в поперечном сечении и могут быть легко удалены из облицовки.After the concrete 4 has hardened, water or air is released from the pipes. Pipes are sharply reduced in cross section and can be easily removed from the lining.
Оставшиес пустоты между породой и облицовкой заполн ют по.т высоким давлением цементным раствором, причем давление в них поддерживаетс до полного отвердевани раствора. Благодар облицовка будет напр женной в отдельных местах подобно тому, как напр гаетс обыкновенна железобетонна труба при помощи предварительно напр женной кольцевой арматуры.The remaining voids between the rock and the lining are filled with high pressure cement mortar, and the pressure in them is maintained until the mortar solidifies. Thanks to the lining, it will be stressful in some places, just as ordinary reinforced concrete pipe is stressed with a pre-stressed ring reinforcement.
Нагнетание раствора в отверсти 7 (фиг. 3) без вытекани его можно осуществить весьма просто. Дл этого поперек сечени тоннел став т присоедин емую отростком 3 металлическую трубу-распорку 6. Один 1конец трубы упираетс в резиновую прокладку 8, уплотн ющую соединение со стенками отверсти 7, в котором установлен обратный клапан 9 с целью предотвращени утечки раствора. Другим концом труба 6 опираетс на домкрат 5, который лежит на облицовке. При по .мощи домкрата обеспечиваетс плоптюе прилегание трубы 6 к резиновой прокладке 8.The injection of the solution into the holes 7 (Fig. 3) without leakage can be carried out very simply. For this, a metal pipe-brace 6 is attached across the tunnel cross-section 3. One pipe end abuts against a rubber gasket 8 sealing the joint with the walls of the hole 7 in which the check valve 9 is installed to prevent leakage of the solution. The other end of the pipe 6 rests on the jack 5, which lies on the lining. With the help of the jack, it is ensured that the pipe 6 adjoins the rubber gasket 8.
Дл облегчени удалени резиновой трубы из облицовки можно взамен одного отрезка 2 нрименить несколько отрезков эластичных труб, как это изображено пунктиром на фиг. 2.In order to facilitate the removal of the rubber pipe from the lining, it is possible to replace several pieces of elastic pipes instead of one piece 2, as shown by the dotted line in FIG. 2
