Description

Layered sampler for sediment and roadbed soil of road drainage system Technical Field The invention relates to the technical field of environmental monitoring and soil surveying equipment, in particular to a layered sampler for sludge and roadbed soil of a road drainage system. Background The layered sampler for sludge and roadbed soil in road drainage system is one professional equipment for collecting sludge and roadbed soil samples in different depths in road drainage system to analyze its components, properties and influence on road structure and environment. In the prior art, after stratified sampling is finished, some road drainage system silts and roadbed soil stratified samplers are easy to pollute or confuse with silts or soil of other soil layers when samples are taken out, and then, data distortion, traceability failure, engineering misjudgment and treatment inefficiency can be caused.
