Renovation and construction of new lines of railway construction investment construction costs become an important factor

With the leaps and bounds and the railway passenger line construction climax, the national railway operating mileage increasing rapidly, both line speed transformation and construction of new lines of railway  Polycrystalline diamond  investment construction costs become an important factor. Is necessary to ensure a safe and smooth rail transport, but also to minimize construction costs, construction of the line must implement  polycrystalline diamond  and strictly control the use of the economic rationality of the line materials. In addition to the management of the project cost conscious, but also need to be equipped for the construction of metering equipment. This topic proposed a "track bed profile measurement system" for the field statistics line with the amount of solid ballast provides a fast and accurate measurement methods, to facilitate the project budget;
