How can the construction party ensure that each layer of soil foundation meets the required standards? It’s not practical to wait until the final inspection by the supervisory department to conduct the last-minute testing, right?
Traditional methods such as sand pouring, cutting ring, and nuclear density testing are either time-consuming or involve radiation, which can be cumbersome for the construction party. So, is there a simple and convenient device available?
Of course, there is. This article will introduce a compaction density gauge equipped on a steel-wheeled drum roller, which can measure density while moving alongside the roller. The roller operator can determine whether the compaction meets the standards while working.
- The main principle is to use an acceleration sensor to measure acceleration information, which comes from the rebound force of the ground on the steel wheel.
- Measurement indicators: Within a certain road surface range, measure the acceleration and check if the values are within the standard range.
- The “acceleration” range is 0-16g, with an initial value of 0. Under normal circumstances, certain acceleration value meets the compaction requirements. This is based on a large amount of experimental data, combining traditional sand pouring methods and circular blade methods.
- The comprehensive “measurement” value range is 0-500, with an initial value of 0. Typically, certain measurement value meets the compaction requirements, also has an optimal value, all based on a large amount of experimental data.
- Please note that this method is generally not used as an acceptance standard but rather as an auxiliary verification tool for construction units to conduct their own quality checks.
- This equipment can meet the IP65 for display, IP67 for sensor. In China, over the past six months, there has been a gradual increase in project applications.
- Equipment exported overseas are all standalone versions and do not collect backend data.
