Hydrologic observation device capable of penetrating frozen wall

Abstract

The invention relates to a hydrologic observation device capable of penetrating a frozen wall. The hydrologic observation device comprises a plurality of hydrologic holes formed in the length direction of an inclined shaft or horizontal and inclined frozen construction passage; the hydrologic holes are formed in a way of being vertical to the ground and extend into the middle non-frozen region of the frozen wall; a pressure detection pipe is introduced into the hydrologic holes; water passing holes are formed in the pipe body, positioned in the non-frozen region of the middle of the frozen wall, of the pressure detection pipe; detection oil liquid is introduced into the pressure detection pipe; a pressure detection device used for detecting the inside pressure is arranged on the pressure detection pipe; during the inclined shaft frozen construction, the hydrologic holes are drilled; the pressure detection pipe is guided into the hydrologic holes; the detection oil liquid is pressed into the pressure detection pipe; the frozen closure condition of the frozen wall is obtained through observing the number change of the pressure detection device; the inclined well digging time is precisely determined.

Description

technical field [0001] The invention relates to the technical field of freezing construction methods, in particular to a hydrological observation device capable of passing through frozen walls. Background technique [0002] During the construction of inclined shafts or other horizontal and inclined passages, if the freezing construction method is used for construction, freezing holes are drilled on the ground or drilling holes are arranged horizontally and obliquely, and multiple freezing holes are arranged along the length of the inclined shaft. For the closure of inclined wells or other horizontal and inclined passages, freezing holes are also drilled at both ends of inclined wells or other horizontal and inclined passages, and freezing pipes are introduced into the freezing holes. A non-frozen section is set at the position of the inclined shaft or other horizontal and inclined passages. After the above-mentioned frozen pipe is arranged, the medium is passed into the froz...
