rørprøve

A rørprøve, often translated as a "tube sample" or "core sample" in English, is a method used in various fields, particularly in soil mechanics and environmental science, to extract a cylindrical portion of material for analysis. The process typically involves using a hollow tube, often made of metal, which is driven or pushed into the ground. As the tube penetrates, it collects a continuous or discrete sample of the soil or sediment within its hollow core.

The purpose of a rørprøve is to obtain a relatively undisturbed sample that preserves the natural stratification, density, and moisture content of the material. This is crucial for accurate testing of properties such as soil strength, permeability, and composition. The collected sample is then carefully removed from the tube and transported to a laboratory for detailed examination.

Applications of rørprøve technology are widespread. In civil engineering and construction, it is used to assess the suitability of ground for building foundations and infrastructure projects. Environmental investigations frequently employ rørprøve to collect soil and groundwater samples for testing for contaminants. In geology, it can be used to study soil profiles and historical depositional environments. The diameter and length of the tube, as well as the method of insertion, are chosen based on the specific requirements of the investigation and the nature of the material being sampled.
