Three-dimensional soil pressure cell complete set application device and implementation method thereof

Abstract

The invention provides a three-dimensional soil pressure cell complete set application device which comprises a telescopic guide rod screwed through a thread, a three-dimensional soil pressure cell fixing base, a connecting control, a three-dimensional soil pressure cell and a plurality of data wires, wherein the telescopic guide rod screwed through the thread and the three-dimensional soil pressure cell fixing base are connected through the connecting control; and a plurality of wires of the three-dimensional soil pressure cell are gathered into one data bus. The invention further provides animplementation method of the three-dimensional soil pressure cell complete set application device. The three-dimensional soil pressure cell complete set application device has the beneficial effectsof overcoming the defect that the buried angle and depth of the three-dimensional soil pressure cell cannot be determined during the site application process and realizing application of the three-dimensional soil pressure cell in original state soil mass testing. When the three-dimensional soil pressure cell complete set application device is applied in practical engineering, the precision of a testing result can be improved. With adoption of the implementation method of the three-dimensional soil pressure cell complete set application device, the time is saved and the construction efficiencyis improved.

Description

technical field [0001] The invention is a complete application device of a three-dimensional earth pressure cell and an implementation method thereof, and is especially suitable for problems such as fixed placement, angle determination and buried depth of the three-dimensional earth pressure cell in the actual construction process. Background technique [0002] The three-dimensional stress state is an important basis for the study of soil strength and deformation. Therefore, the measurement of the three-dimensional stress value inside the soil is very important. Because of its unique advantages, the three-dimensional earth pressure cell is widely used in the test of the internal stress of soil in actual engineering. The three-dimensional earth pressure cell is buried in the soil to be tested, connected with data wires and connected to the data acquisition system. Measure the stress value at any point in the soil. [0003] However, the calculation formulas derived from comm...
