Quality control of track bed for railway construction! SRID
Automatic Scanning RI Density Moisture Meter 'SRID' (Slid) SRDM-PWS30C
Ideal for managing coarse aggregate embankments! The measurement area is more than 10 times that of conventional types!
In the evaluation of subgrade in railway construction, quality management of embankments is crucial to ensure the safe operation of trains. In particular, the density and moisture content of the subgrade significantly affect its strength and durability; improper management can lead to subsidence or deformation of the subgrade, ultimately resulting in derailment accidents. The SRID achieves more than ten times the measurement range compared to conventional RI density moisture meters, enabling rapid and extensive measurements. This allows for efficient management of subgrade quality, contributing to safe railway operations. 【Application Scenarios】 - Quality management of subgrade in new railway construction - Quality assessment in repair and improvement work of existing subgrades - Compaction management of embankments 【Effects of Implementation】 - Improved efficiency in quality management through extensive measurements - Automatic correction of unevenness effects using non-contact distance sensors - Shortened construction periods due to rapid measurements - Assurance of safe railway operations

basic information
【Features】 - It is an automatic floating scanning type (floating height of 5 cm), so it is unaffected by surface irregularities. - It measures by rotating within a circumference of 80 cm, achieving more than 10 times the measurement area compared to our ANDES. - The measurement time is a total of 2 minutes, with 1 minute for BG measurement at one location and 1 minute for on-site RI measurement. - Standard measurements are unnecessary as it automatically corrects for source attenuation. 【Our Strengths】 Since our establishment in 1974, we have developed numerous technologies that utilize RI (radioisotope) measurement technology in the construction field. As an "RI measuring instrument manufacturer," we handle everything in-house from development to manufacturing, rental, and maintenance. As a "construction consultant," we conduct on-site surveys utilizing RI technology, in addition to standard ground investigations and soil tests. With these two pillars, we demonstrate comprehensive capabilities and contribute to ensuring reliable quality at construction sites.

Company information
Since our establishment, we have developed many measurement technologies that utilize various types of radiation emitted by radioisotopes, particularly gamma rays and neutron rays, in the construction field, specifically the RI method. The characteristics of the RI method are "non-destructive," "rapid," and "high precision." Currently, based on the development of unique measuring instruments that leverage these characteristics and the proposal of investigation methods, we focus on consulting that comprehensively addresses issues related to ground and soil construction by combining soil and geological surveys. Additionally, we also engage in the sale and rental of these RI instruments. Please feel free to contact us if you have any requests.
