PROCESS FOR WASHING UNDERGROUND WORKS IN SOFT WATER-BEARING ROCKS

摘要

the invention refers to a process of sapare of works such tunelelorde horizontal underground subway big collectors, channel diameter.the galleries of aductiune or running to hidrocentrare, located in unstable rock, strong aquifers.according to the process of underground works sapare probes frosting is post excavatiei profile vertical or inclined so that the durations of solidification in space contained in wateri have two ranks of probes on a partesi outer wall protection, on the other hand to be equal.frosting and probes located in profile of extract of massive frozen at the frontline work a distance to be traveled by the surgery to be traveled by the operationexcavation before natural freezing segment devoid of probes to liquidate the frozen.on the process of solidification control, groundwater and the phases of technologicalobservation is carried out by simasuratori on water level in wells equipped with hydraulic filter probes located in the longitudinal plane of symmetry of the tunnel at distances of 30...35 m between them or in other points where the solidification conditions water are the most unfavourable.
