Umbrella stepped displacement meter anchor head for Soft Composite formations

A Soft Composite formations umbrella stepped displacement meter anchor head of the anchor head comprises a main anchor head connection sleeve, connection sleeve under the umbrella anchor system, special multilayer modular spring system the main indium wire and drilling; within a borehole, the upper end of the main anchor head is connected via a first fastening sleeve and latch on the lower end of the lower connecting tube is connected via a second fastening latch; primary indium by spring wire shaped multi-layer composite system is connected with the mushroom anchor system. Displacement meter anchor head of the present invention consists of a multilayer composite profiled spring system synchronization were driven movable arm anchor flukes telescopic ladder, with its instantaneous release of elastic energy leaving the movable arm ladder telescopic anchor flukes phased drill body buried completed anchor with anchoring effect, strong skid resistance, wide adaptability to soil, low cost, reliable measurement results and other advantages.
