Installation method of deep earth pressure cell

Abstract

The invention relates to the technical field of soil pressure monitoring, and discloses a method for installing a deep earth pressure cell. The specific installation steps are as follows: 1) drilling a hole at a selected embedding position, and drilling the hole to a required depth; 2) the fixer includes A fixed plate and two fixed rings, the two fixed rings are respectively fixed at both ends of the fixed plate, and the end of the bracket is connected with the fixed ring; 3) The fixer has a storage slot, and the earth pressure box is placed in the storage slot; 4) Insert the connected fixture and bracket into the completed borehole according to the designed depth and direction, and insert the lower end of the bracket into the soil; 5) Use coarse sand to backfill the pores; 6) After the detection and calibration are normal, according to the design requirements Monitor the soil pressure data; use the bracket to insert the fixer with the earth pressure cell into the soil to prevent rotation, prevent the direction of the earth pressure cell from shifting, and keep it in the correct direction at all times to ensure that the earth pressure cell exerts pressure on the soil Accuracy of monitoring.

Description

technical field [0001] The patent of the present invention relates to the technical field of soil pressure monitoring, in particular, it relates to the installation method of a deep earth pressure box. Background technique [0002] Earth pressure cells are widely used to measure the compressive stress of soil inside various structures in the field of geotechnical engineering. Earth pressure monitoring on the surface and inside the soil, and timely data acquisition equipment to obtain the required data results. [0003] At present, there are many defects in the deep earth pressure embedding methods. The embedding direction of the earth pressure cell is not easy to control, and it is easy to have deviations between the actual embedding direction and the preset direction, resulting in inaccurate monitoring data and failure to obtain the required data. [0004] Therefore, in order to meet the test requirements of the stress field of deep soil, it is urgent to solve the problem ...
