The high-performance concrete cleaned by the sand washer has a high volume stability, that is, the concrete should have a lower heat of hydration in the early stage of hardening and a smaller shrinkage deformation in the later stage of hardening.

High-performance concrete has a long service life. For some special parts of special projects, it is not the concrete strength that controls the structural design, but the durability. The sand washer can remove impurities in the aggregate, and can make the concrete structure work safely and reliably for more than 50-100 years. It is the main purpose of high-performance concrete application.

In the production of sand washer, the regulator is mounted on the locomotive casually. It is not installed vertically as before, which will cause the platinum contacts of the regulator to vibrate due to uneven road surfaces or locomotive vibration, which will affect the quality of power generation and work stability.

Sand washer digital surveying and mapping technology is an emerging surveying and mapping technology that has emerged with the development of computers and network technology and the intelligentization of measuring instruments.

The concept of digital China and digital cities and the launch of related digital projects, especially the development of advanced technologies such as global positioning systems (GPS), geographic information systems (GIS), photogrammetry and remote sensing (RS), and digital mapping and ground surveying, The method and method of engineering measurement have produced profound changes. The service area of engineering measurement has also been extended accordingly, and it is developing towards the automation, real-time and digitalization of measurement data collection and processing, making sand washing machines more efficient and effective.
