Abstract
A multi-depth deflectometer provides use and fabrication advantages. It is comprised of a head member that normally is disposed at the very mouth of a bore hole, an elongated tail member extending down through the bore hole. Displacement transducers are removably positioned within the head member which can be opened from the surface. The transducers can be easily placed in or removed by hand. The first trackings of subsurface deflections are done through mechanical deflection anchors located at desired measuring levels within the tail member. The deflection anchors have transverse-bite actuators and are each separately in vertical-actuation communication with one of the transducers. A method of implementing the MDD reflects the use and fabrication advantages also.
Claims8
A multi-depth deflectometer comprised of:
- a head member;
- an elongated tail member having a proximal end and a distal end, said tail member extending from said proximal end longitudinally downward from said head member;
- a plurality of independent displacement-transducer assemblages, each assemblage comprising a displacement transducer and a deflection anchor, said deflection anchor having a transverse-bite actuator and being in vertical-actuation communication with said transducer,
- said transducer of each assemblage being located within said head member;
- said deflection anchor of each assemblage being located in said tail member and being a member of a longitudinal alignment of said deflection anchors.
