Abstract

The invention discloses a transmitting / receiving coil for underground nuclear magnetic resonance water detection. The transmitting / receiving coil comprises a fixed shaft (1), a central support (2), an electromagnetic induction coil (3), a Y-shaped frame (4), a spherical device (5) and opening-closing devices (6); a ball head (12) of the spherical device (5) is connected to the front end of the fixed shaft (1), the divergent Y-shaped frame (4) is fixed on the outer wall of a ball socket (13) of the spherical device (5), the top end of the Y-shaped frame (4) is fixedly connected to an intersection angle of the square central support (2), the four opening-closing devices (6) are arranged on four edges of the central support (2), and the electromagnetic induction coil (3) is wound along the edges of the opening-closing devices (6). The transmitting / receiving coil disclosed by the invention has the advantage of increasing the test depth of underground prediction detecting water.

Description

technical field [0001] The invention belongs to the technical field of advanced geological prediction of underground engineering, and in particular relates to a transmitting / receiving coil for underground nuclear magnetic resonance water exploration. Background technique [0002] At present, my country has become the country with the largest number of tunnels, the largest construction scale and the fastest development speed in the world. With the acceleration of my country's infrastructure construction process, more long tunnels, tunnels and other underground projects will be built in the fields of transportation, water conservancy and hydropower, and mineral resource development. These tunnel projects generally have significant characteristics such as large buried depth, long tunnel line, and complex hydrogeological conditions. In addition, it is difficult to find out the hydrogeological conditions along the tunnel in the geological survey work in the early stage of constru...
