STRUCTURE FOR COUPLING SETTLEMENT ROD AND SETTLEMENT ROD PROTECTING PIPE USED TO MEASURE SOFT GROUND SETTLEMENT

摘要

The subject innovation is soft in the soil relates to the raised ground subsidence measuring apparatus for measuring the degree of depression, weakness, at least two or more phase and down connections in accordance with the depth of the fill layer for deriving a consolidation settlement of the ground that are used subsidence rod and by improving the connection part of the settlement rods protective tubes shorten the working time of the sinking rods, and settlement rods connecting the protective tube and, to recycling is easy after use, without using a separate tool-touch fitting way to number the operator immediately needed in the field it can be easily connected to it as quickly with its purpose as to improve the ease of use allows the operator to St. gailcheung.; The devised for achieving this end is characterized in that in a raised ground subsidence measuring apparatus consisting of a plate and a sink, sink rod, sinking rods and the protective tube, a support,; The sink rod sink rod subsidence that by using a fixing means such as welding a square tube or a cylinder-fit connectors of which has a fitting space at one end of the protective tube attached configuration, respectively, and fitted with a single touch in the fitting recess of the fitting connecting pipe the other end of the rod and protective tube there will sink rod that has been characterized as elastically supported by the inner peripheral surface parts of the fitting space bar depression and depression rod protective pipe is rotated, or form a resilient holding piece not fall.
