[0032] The technical problem to be solved by this application is a device and method for quickly obtaining undisturbed soil samples in batches, which can be applied to cohesive and non-cohesive soils of different particle sizes. The main purpose of the technical solution of the present application is to quickly obtain undisturbed soil samples in batches. The device and method for quickly obtaining undisturbed soil samples in batches adopted by this application to solve its technical problems are briefly described as follows in the principle and process:
[0033] 1) Grooving
[0034] ①For fine-grained soils such as clay, sand, and gravel: use a scraper and a spoon to carve grooves with a width of 6cm-8cm and a depth of 10cm-30cm on a representative soil sample. For non-cohesive soil, water can be properly sprinkled before the groove is carved. , in order to keep the soil sample in its original state.
[0035] ②Coarse-grained soil containing pebbles: Shallow trenches with a wi...
