Abstract
1. Способ сооружения подземной выработки при щитовой проходке с использованием элементов сборной кольцевой железобетонной, чугунной или из любого другого материала обделки, включающий разработку грунта механизированным щитом, тампонаж заобделочного пространства через отверстия в элементах сборной кольцевой обделки тампонажным раствором, отличающийся тем, что на начальном этапе проходки производят разработку забоя и заполнение части заобделочного пространства на длине 0,25-0,75 длины элемента сборной кольцевой обделки за первым после щита кольцом обделки тампонажным раствором с длительным сроком схватывания, следующий этап разработки на длине 0,5-1 длины элемента сборной кольцевой обделки ведут с подачей в заобделочное пространство смеси тампонажного раствора с ускорителем схватывания, а вслед за этим на этапе технологической остановки щита для монтажа следующего кольца обделки давление тампонажного раствора в заобделочном пространстве за первым после щита кольцом обделки поддерживают путем подачи тампонажного раствора с длительным сроком схватывания в зону участка заобделочного пространства, первоначально заполненного тампонажным раствором с длительным сроком схватывания, и далее этапы разработки грунта и тампонажа заобделочного пространства повторяют. ! 2. Способ сооружения тоннелей по п.1, отличающийся тем, что переход на нагнетание тампонажного раствора с ускорителем схватывания после первостепенного нагнетания тампонажного раствора с длительным сроком схватывания начинают после того, как из-под щеток щитового комплекса освобождается следующее инъекционное отверстие. ! 3. Способ сооруже 1. A method of constructing an underground mine during paneling using elements of a precast ring reinforced concrete, cast iron or any other lining material, including the development of soil with a mechanized shield, grouting of the surrounding space through openings in the elements of the precast ring lining with grouting mortar, characterized in that at the initial stage penetrations produce the development of the face and filling of part of the embossment space at a length of 0.25-0.75 of the length of the prefabricated ring lining element after the first after it is with a grouting lining ring with a long setting time, the next development stage, at a length of 0.5-1 the length of the prefabricated annular lining element, is carried out with a mixture of grouting slurry with a setting accelerator, and then at the stage of technological shutdown of the panel for installation of the next lining rings, the pressure of the cement slurry in the lining space behind the first lining ring after the shield is maintained by supplying the grouting mortar with a long setting time to the area ka embossment space, originally filled with grouting mortar with a long setting time, and then the stages of soil development and grouting of embellishment space are repeated. ! 2. The method of constructing tunnels according to claim 1, characterized in that the transition to injection of grouting mortar with a setting accelerator after the primary injection of grouting mortar with a long setting time is started after the next injection hole is released from under the brushes of the shield complex. ! 3. The method of construction
