Umbrella-shaped step type multipoint displacement meter anchor head for soft soil compound stratum
The invention relates to an umbrella-shaped step type multipoint displacement meter anchor head for soft soil compound stratums. The anchor head comprises a main anchoring head, an upper connecting sleeve, a lower connecting sleeve, an umbrella-shaped anchoring system, a special-shaped multilayer combined spring system, a main indium steel wire and a drill hole, wherein in the drill hole, the upper end of the main anchoring head is connected with the upper connecting sleeve through a first fastening lock clamp, the lower end of the main anchoring head is connected with the lower connecting sleeve through a second fastening lock clamp, and the main indium steel wire is connected with the umbrella-shaped anchoring system through the special-shaped multilayer combined spring system. According to the multipoint displacement meter anchor head, movable anchoring arm step telescopic anchor claws are respectively and synchronously driven by the special-shaped multilayer combined spring system, and the instantaneously released elastic energy is utilized, so that the movable anchoring arm step telescopic anchor claws are drilled into the soil body stage by stage for completing the anchoring. The umbrella-shaped step type multipoint displacement meter anchor head has the advantages that the anchoring effect is good, the anti-slip capability is high, the soil layer adaptability is wide, the cost is low, the measurement result is stable and reliable, and the like.
