The bearing capacity, settlement evaluation, and measurement equipment of in-situ used by standard penetration test equipment

摘要

The present invention includes the steps of drilling depth to the design basis for the installation to install the rod tip to a split barrel sampler, While the loading weight on the upper knocking heads loading multiple stages by measuring the settlement by the loading weights, the evaluation of the bearing capacity and settlement wonjiban using the standard penetration test device for static bearing capacity reliable and accurate method to assess and spare wonjiban relates to a measuring device. ; The present invention, drilling depth to be based on the design and installation, comprising: a first step of close contact with the standard penetration test split barrel surface drilling rod fitted at the tip of the distal end of the sampler device; Instrument equipped with a bar attached to a digital displacement sensing in the standard penetration test body and has a magnetic force corresponding to the load, but with a base plate attached to the sink side, touch-sensing digital displacement meter bar on the side of the sink base plate the second step so as to match the direction; A third step of applying a load to the load static loading, but the installation and the lower plate to the upper end of the knocking head arbitration, mediation and stacked into the lower plate and in various stages; And static load according to the load added to the sensing step to detect a bar state to the sink plate is lowered digital displacement measuring instruments standard penetration test device to measure the settlement by applying a sensing signal to a fourth step of evaluating the strength properties of the wonjiban provides the bearing capacity and settlement of wonjiban using assessment methods.
