Problems solved by technology
[0002] 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.

Embodiment Construction
[0015] like figure 1 As shown, a rolling compacted concrete conveying method for gentle slope terrain, the concrete conveying system is composed of the following equipment: aggregate device 1, one or several concrete conveying belt conveyors 2, chute 3, transfer hopper 4, vacuum chute 5, support Column or scaffolding 6, crane beak elbow 7. On the basis of the original vacuum chute concrete conveying system (including vacuum chute 5, material collecting device 1, support column or scaffolding bracket 6, crane beak elbow 7), by adding concrete conveying belt conveyor 2, chute 3, and transfer hopper 4 , so that the vacuum chute can be arranged according to its own technical characteristics and construction requirements, so that the concrete downhill slope and the car material receiving space in the pouring warehouse can meet the requirements of vacuum chute for concrete transportation.
[0016] Concrete transportation methods are as follows: concrete transportation dump truck, o...

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 ofthe 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.
Description
technical field [0001] The invention relates to a concrete conveying method, in particular to a roller compacted concrete conveying method for gentle slope terrain in water conservancy and hydropower projects. Background technique [0002] 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. Contents of the invention [0003] The purpose of the present invention is to provide a gentle slope terrain roller compacted concrete delivery method, which overcomes the shortcomings o...
