Abstract
Изобретение относитс к мостостроению и может быть использовано при реконструкции железобетонных пролетных строений при наращивании ригел опоры или замене опорных частей. Цель изобретени - снижение трудоемкости работ за счет обеспечени одновременного равномерного подъема смежных концов соседних пролетных строений. Способ подъема железобетонных балочных пролетных строений включает вырубку отверстий 4 в под- опорных зонах балок 1 в плитах между концевыми диафрагмами 5. Под балки 1 подвод т поддерживающие траверсы 8, размещают их параллельно продольной оси пролетных строений и опирают на диафрагмы 5. Через отверсти 4 на опоры 3 опускают домкраты 6, на штоки 11 которых устанавливают упорные траверсы 12. Траверсы 8 и 12 соедин ют друг с другом т жами 19. Затем включают в работу домкраты 6 и поднимают одновременно смежные концы соседних пролетных строений. 7 ил. (ЛThe invention relates to bridge construction and can be used in the reconstruction of reinforced concrete spans when building the transom support or replacing support parts. The purpose of the invention is to reduce the labor intensity of the work by ensuring the simultaneous uniform lifting of the adjacent ends of the adjacent superstructures. The method of lifting reinforced concrete girder structures includes cutting holes 4 in the support areas of girders 1 in the plates between the end diaphragms 5. Support beams 8 are brought under beams 1, placed parallel to the longitudinal axis of the span structures and supported on diaphragms 5. The supports 3 lower the jacks 6, on the rods 11 of which they install the stop bar 12. The cross braces 8 and 12 connect the straps 19 to each other. Then the jacks 6 are put into operation and simultaneously the adjacent ends of the adjacent span structures are lifted. 7 il. (L
