Sludge solidification in-situ test method

Abstract

The invention relates to the field of sludge solidification detection, in particular to a sludge solidification in-situ test method. The method comprises the following steps: arranging piezoelectric solidified soil test points in parallel at multiple points of sludge in situ, distributing the piezoelectric solidified soil test points at equal intervals in the vertical depth, and connecting the test points with a data collector through conductive solidified soil. Each test point is composed of piezoelectric solidified soil, a super-elastic rubber film sleeve, a net-shaped mold, a plastic hose and conductive solidified soil. The invention provides a measuring point arrangement requirement for measuring a sludge solidification state of piezoelectric solidified soil; compared with a traditional arrangement scheme, the provided method has the advantages: the density of measuring points is higher, piezoelectric solidification states of different depths can be measured, and a testing scheme is provided for related research on sludge solidification in the future; the conductive solidified soil is prepared, and a new thought is provided for a soil body internal sensor arrangement method; the measurement sensor is piezoelectric solidified soil, and the influence on the property of an in-situ soil body is low; and compared with a traditional scheme, the measurement result is more accurate.

Description

technical field [0001] The invention relates to the field of silt solidification detection, in particular to an in-situ test method for silt solidification, which is applied to the arrangement of measuring points for in-situ detection of the silt solidification state in dredging and dredging works such as rivers, lakes and port channels. Background technique [0002] At present, many cities in China are dredging around rivers or lakes to improve the water environment. However, due to the constraints of the city's environment, these dredging projects are mostly dredged by dredging ships, transported by pipelines for a long distance to a certain area, and then piled up to dry naturally. Not only does it occupy a large area and the treatment cycle is long, but it also brings risks such as pollution transfer. Therefore, river and lake polluted silt dredging and mud deep dehydration and solidification treatment technologies will have a good application prospect in later water en...

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
