Inverted M hook type-nail type combined, multi-point displacement-meter anchor head for soft-soil compound strata
The invention discloses an inverted M hook type-nail type combined, multi-point displacement-meter anchor head for soft-soil compound strata. The inverted M hook type-nail type combined, multi-point displacement-meter anchor head comprises a protection shell, six inverted M hook-type anchors, six nail-type anchors, a fixing rack, a combined wire spring, a stainless invar wire, etc. The front end of each inverted M hook-type anchor is designed to have an inverted-hook sharp-angled shape, and the outer edge is designed to have a cutting-edge shape where an arc is connected with straight lines in a fitting manner. Each nail-type anchor has a circular shape, with the front end being in the shape of a nail point. The combined wire spring comprises a vertical wire spring, first horizontal wire springs and second horizontal wire springs, wherein the first and second horizontal wire springs are connected to the vertical wire spring. The fixing rack, which serves as a platform for stabilizing the combined wire spring, is arranged inside the anchor head protection shell 1 and comprises a first fixing rack, a second fixing rack and a third fixing rack. The inverted M hook type-nail type combined, multi-point displacement-meter anchor head of the invention has the advantages of good anchoring effect, strong adaptability to soil strata, low cost, good generality, stable and reliable measurement result and the like.
