Physical settlement gauge with saw-toothed supporting strips at bottom

Abstract

The invention discloses a physical settlement gauge with saw-toothed supporting strips at the bottom. The physical settlement gauge consists of a fixed bottom plate (3), measuring bars (1) and a PVC (polyvinyl chloride) protection pipe (2), wherein the measuring bars (1) are arranged in the center of the fixed bottom plate (3); the PVC protection pipe (2) is sheathed at the external part of the corresponding measuring bars (1); the measuring bars (1) and the PVC protection pipe (2) are in parallel with a central axis; the measuring bars (1) are connected with the fixed bottom plate (3) through a thread; the measuring bar (1) is perpendicular to the fixed bottom plate (3); and multiple measuring bars (1) can be mutually connected; the length of the PVC protection pipe (2) is slightly smaller than the length of the measuring bar (1); at least four supporting strips (4) are arranged at the bottom of the fixed bottom plate (3); and the bottoms of the supporting strips (4) are designed to be saw-toothed. By adopting the structure, the physical settlement gauge with saw-toothed supporting strips at the bottom has the advantages that the accuracy of the settlement gauge can be improved, the price is reduced, the settlement gauge is not interfered by the external world and the bottom stability is good.

Description

technical field [0001] The invention relates to a settlement instrument, in particular to a physical settlement instrument with a zigzag support bar at the bottom. Background technique [0002] At present, the sedimentation instrument generally adopts the electromagnetic sedimentation instrument. The sensor used is designed according to the principle of electromagnetic induction. The magnetic induction sedimentation ring is buried in the underground points to be measured by drilling holes in advance. When the sensor passes through the magnetic induction ring, a The electromagnetic induction signal is sent to the ground instrument display, and an audible and visual alarm is issued at the same time. Read the scale value corresponding to the steel ruler on the marked point of the orifice, which is the depth of the settlement ring. Subtracting each measured value from the previous measured value is the settlement of the measuring point. The disadvantage of the sedimentation me...
