As shown in FIG. 1, the underground displacement meter embedding auxiliary assembly comprises an outer sleeve 1 for accommodating a displacement meter 8 and a cover plate 2 detachably connected to the outer sleeve 1, wherein the outer sleeve 1 and the cover plate 2 are both preferably made of PVC (polyvinyl chloride). Be provided with the external screw thread on apron 2's the lateral wall, be provided with the internal thread with external screw thread threaded connection on outer tube 1's the inner wall, 2 threaded connection in outer tube 1's top below of apron for at the in-process of connecting apron 2, the soil body on the drilling lateral wall has had the design on outer tube 1 upper portion can not be loose, has improved the convenience of the in-process operation of connecting apron 2. The threaded connection between the cover plate 2 and the outer sleeve 1 can be added with a waterproof gasket or a plugging agent to prevent water from entering the displacement meter.
The top of apron 2 is fixed with rotation portion 21, is provided with anti-skidding line on the outer wall of rotation portion 21, and anti-skidding line can be the line of increase frictional force such as rhombus annular knurl. The turning part 21 facilitates manual rotation of the cover plate 2, improving convenience of operation.
A cable storage cavity 4 is reserved between the cover plate 2 and the displacement meter, and a cable through hole 5 penetrates through the cover plate 2. The cable storage cavity 4 is used for storing the second cable 83 before excavation, and the cable through hole 5 is used for allowing the first cable 82 to pass out before excavation.
The cover plate 2 is fixed with a suspension wire 6, the top surface of the cover plate 2 is fixed with a fixing ring 22 for binding the suspension wire 6, and one end of the suspension wire 6 is connected with the fixing ring 22.
