Specific embodiment
The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
Embodiment 1
As shown in Figs. 1-5, a kind of bridge pile foundation displacement detector, including several sensors 2 being arranged in pile foundation 1,
And the signal picker 4 of connection sensor 2, it further include the spherical protective shell 6 for surrounding sensor 2 and being arranged, protective shell 6 includes
The resistance to compression layer 62 in outside and the electro-magnetic screen layer 64 of inside.
Specifically, the present embodiment bridge pile foundation displacement detector includes two sensors 2 along short transverse distribution.
It is equipped with installation interconnecting piece 66 outside protective shell 6, such as offers the lug of connecting hole, stake can be fixed by screws in
In base 1 on reinforcing bar 3.In addition protective shell 6 includes two hemispherical Shells 68 being detachably connected, and two hemispherical Shells 68 can mutually block
It closes, specifically, the open end side wall of a hemispherical Shell 68 is equipped with elasticity prominent 682, the open end side of another hemispherical Shell 68
