Problems solved by technology
In the transportation of roller compacted concrete in the hydropower industry, in addition to the traditional vehicle transportation, cable machine or tower crane with hanging tank transportation, and Rotek belt conveyor transportation, there is also a relatively advanced and simple concrete transportation technology-vacuum chute transportation technology, but this technology One disadvantage is that its conveying downslope must be greater than a certain angle, which is not suitable for concrete conveying in construction projects on gentle slope terrain.

The invention provides a method for conveying roller compacted concrete in various topographies with mild slopes, and the method includes the following steps: according to the actual topography, parameters from the dam surface to the dam bottom such as the horizontal section length of the working-face, the height difference of the mild slope, the angle of the slope surface, the characteristics of the rock surface, etc. are comprehensively mastered; when the blanking angle is smaller than 42 DEG, concrete is conveyed by adopting the combination of a belt conveyer and a vacuum delivery conduit. According to the actual topography on site, the concrete belt conveyer, the vacuum delivery conduit and a hose pipe are effectively combined to form a complete conveying system, the belt conveyer is connected with the vacuum delivery conduit through a collecting hopper, the vacuum delivery conduit is connected with the hose pipe through a collecting hopper, and upright columns, horses and elbows are used for connecting and fixing the belt conveyer, the vacuum delivery conduit, the hose pipe and the collecting hoppers. The invention effectively integrates several economical and practical conveying means according to the principles of adaptation to local conditions, thereby achieving the purpose of conveying the concrete and minimizing the cost on the premise that the concrete conveying quality is ensured.
