Description
Technical field
Soil data testing field is the utility model is related to, particularly belongs to a kind of high precision soil dilatometer.
Background technology
At present, when being measured using conventional soil dilatometer to the swell increment of cohesive soil, often under normal conditions
Carry out, have ignored the influence of the factors such as temperature, the swell increment finally measured is inaccurate, can not meet Practical Project
Need.Meanwhile, it is necessary to artificially survey meter at regular intervals when being measured using traditional dilatometer to cohesive soil swell increment
Once, until expansion is stable when reading difference is no more than 0.01mm twice, operating efficiency is low, and test error is also for data collecting instrument
Greatly.
Utility model content
The purpose of this utility model is to provide a kind of high precision soil dilatometer, the soil swelling data precision measured
Height, test error is small, and operating efficiency is high.
The technical solution of the utility model is as follows：
A kind of high precision soil dilatometer, include casing cylinder, measuring cylinder, casing cylinder bottom is provided with leg, outside
Shell cylinder top is provided with upper lid, and measuring cylinder bottom face is articulated with casing cylinder bottom surface by sphere, is filled with measuring cylinder to be checked
The soil of survey, soil surface lid are equipped with floating piston, and measuring cylinder two bottom sides are fixed with adjutage respectively, in adjutage side wall
Provided with hole for water spraying, adjutage bottom is connected with aqueduct, and measuring cylinder top is provided with closure, and closure is fixed with bottom surface
Strain gauge pressure sensor, overhead floating piston is pressed on strain gauge pressure sensor after soil swelling, and foil gauge pressure passes
Data record analyzer is externally connected with sensor.
Described data record analyzer includes CPU, data receipt unit, data processing unit, display
Unit.
Described closure is provided with multiple air levels.
The utility model realized and measuring cylinder is horizontally disposed with by rotation measuring cylinder different azimuth, what adjutage sprayed
Overhead floating piston after soil swelling is pressed on strain gauge pressure sensor by water, is externally connected with strain gauge pressure sensor
Data record analyzer, data record analyzer is by receiving data, processing data, and by result display processing, measurement
The soil swelling data precision gone out is high, and test error is small, and operating efficiency is high.
