Technical Field
The utility model relates to the technical field of test devices, and particularly relates to a
crustal stress test apparatus.
Background
Modem underground projects are large in scale, and the buried depth is also increased
continuously, and reaches hundreds of meters or even thousands of meters, such as high-stress
tunnels, underground factories, underground nuclear waste storages, deep underground
laboratories, etc. Before the construction of these deep underground projects, planners and
designers urgently need to know the crustal stress field in the project area. Therefore, more and
more crustal stress test methods and devices are developed in the direction of deep drilling. A
foreig deep borehole underwater three-direction strain gauge researched by Swedish National
Electricity Agency has been introduced by Yangtze River Scientific Research Institute in China
and has been significantly improved in practice. A wireless measuring device was added by
Wuhan Institute of Rock and Soil Mechanics of Chinese Academy of Sciences on the basis of a
36-2-model borehole deformation gauge, so that the instrument can be used for wireless
measurement of deep boreholes.
Most of the existing deep borehole measuring instruments are improved on the basis of the
original shallow hole measuring technical solution. The bottomhole instrument feeding device
and method also adopt the device and method for the shallow hole measurement. However, it is
discovered from the in-situ test that the shallow hole instrument feeding device and method
cannot meet the deep hole measurement need. At present, in the propelling process, the common
bottomhole instruments in the market are liable to drop. When the bottomhole instruments
perform the deep borehole measurement, the bottomhole instruments cannot be sent to a target
position once dropping off, which may block the borehole, resulting in failure in stress test.
Therefore, it is necessary to provide a crustal stress test apparatus to solve the above
