A kind of mud solidification in-situ test method

Abstract

The invention relates to the field of silt solidification detection, in particular to an in-situ testing method for silt solidification. The measuring points are connected with the data collector through the conductive solidified soil. The measuring point is composed of piezoelectric solidified soil, superelastic rubber film sleeve, mesh mold, plastic hose, and conductive solidified soil; the present invention proposes a measuring point arrangement requirement for measuring the solidified state of silt for piezoelectric solidified soil; the present invention Compared with the traditional layout scheme, the density of measuring points is larger, and the piezoelectric solidification state of different depths can be measured, which provides a test scheme for future research on silt solidification. The layout method provides a new idea; the measurement sensor in the present invention is piezoelectric solidified soil, which has little influence on the properties of the in-situ soil, and the measurement result is more accurate compared with the traditional scheme.

Description

technical field [0001] The invention relates to the field of silt solidification detection, in particular to an in-situ testing method of silt solidification, which is applied to the arrangement of measuring points for in-situ detection of silt solidification state in dredging and dredging of rivers, lakes and port channels. Background technique [0002] At present, many cities in China are carrying out dredging treatment around rivers or lakes to improve the water environment. However, due to the limitation of the urban environment, most of these dredging projects are dredging by dredging ships, and pipelines are transported for a long distance to a certain area before stacking, and natural sedimentation and drying. It not only occupies a large area, but also has a long processing cycle, and also brings risks such as pollution transfer. As a result, the technology of dredging polluted sludge in rivers and lakes and the deep dehydration and solidification treatment technolo...

AI Technical Summary

Problems solved by technology

Due to the great damage to the soil in the site due to the cross-plate shear test, the number of measuring points on the horizontal plane of the existing in-situ silt solidification detection is about 2-3, and one measurement can only measure the silt solidification state at one depth

[0004] The advantage of the in-situ test technology is that it can comprehensively determine the mechanical indicators of the silt-solidified soil, which is more scientific, but the disadvantage is that a single measuring point can only measure the degree of solidification at a certain depth, and the number of measuring points is limited by the testing equipment. , should not be arranged too much
