Abstract
Изобретение может быть использовано при сооружении тоннелей и труб через основани насыпей железных и автомобильных дорог. Цель - снижение трудо- и мате риалоемкости работ при сооружении тоннел в основании насыпи железной дороги. С двух сторон насыпи 1 производ т забивку шпунтовых элементов ограждени 4, верхние , концы которых соедин ют гибкими т жами 7, проход щими через балластную призму 5. По мере удалени грунта и углублени камер 2 и 3 производ т нат жение гибких т жей 7; что предотвращает деформацию шпунтовых элементов 4. По достижении основани тоннел 1 во входной рабочей камере 2 сооружают упорную стенку , в камеру опускают секции тоннел и осуществл ют их поочередное продавливание при помощи домкратной батареи. 3 ил.The invention can be used in the construction of tunnels and pipes through the foundations of railways and highways. The goal is to reduce labor and material intensity in the construction of a tunnel at the base of a railway embankment. On both sides of the embankment 1, the tongue-and-groove elements of the fence 4 are driven, the upper ends of which are joined by flexible strands 7 passing through the ballast prism 5. As the ground is removed and the chambers 2 and 3 are depressed, the tension of the flexible strands 7 is pulled out; which prevents deformation of the tongue-like elements 4. Upon reaching the base of the tunnel 1, an abutment wall is built into the entrance working chamber 2, sections of the tunnel are lowered into the chamber and they are alternately pressed through with a jack battery. 3 il.
