The utility model belongs to the technical field of roller compacted concrete hyperbolic arch dam construction, especially, relate to full pipe roller compacted concrete buffering conveying system of super hectometre.
Background
The engineering dam site of the Wanjiakou hydropower station is positioned on the Ching Xiang river of the main flow of the Bei Dian river, and is the fourth step power station of the main flow of the Bei Dian river. The water retaining building of the power station is a parabolic roller compacted concrete hyperbolic arch dam, the maximum dam height is 167.50m, the highest roller compacted concrete hyperbolic arch dam in the world at present is limited by the steep hill height slope and the dangerous valley terrain in the dam site area, and the dam body concrete is delivered into a warehouse by adopting a full pipe and automobile mode after being poured to EL.1350.0 m. Two full pipes with the diameter of 800 are arranged between elevations of the dam bodies EL.1350.0m-EL.1452.5m, the average inclination angle is 47 degrees, the total length of a single full pipe is more than one hundred meters, the conveying task of rolling concrete of about 65 ten thousand squares above the dam bodies EL.1350.0m is undertaken, and the average monthly pouring strength is required to be 4-5 ten thousand meters for carrying out the year.
The roller compacted concrete is a dry and hard concrete, generally adopts a through warehouse thin layer continuous construction, and has higher requirements on warehousing strength, concrete workability, aggregate separation and grindability. Because the full pipe system has large conveying height difference and long line, on the basis of ensuring the quality of roller compacted concrete and achieving no blockage and no separation, the concrete conveying capacity is required to be improved, and the new requirements on the aspects of process, materials, equipment performance, field management and the like are met.
In the using process of the full-pipe conveying mode, although the supporting system needs to be in place once and the early investment is high, the problems of aggregate separation and the like can be effectively prevented, and therefore the full-pipe conveying mode is comprehensively considered.
Based on this, the applicant in CN 108193692 a provides a system and method for conveying super-hectometer of full-pipe roller compacted concrete, in which two full pipes arranged in parallel are adopted, and a control valve is installed at a position 1390 height of the full pipes to control the falling speed of the concrete, thereby achieving the purpose of full-pipe conveying. By adopting the conveying system, the problems existing in the actual operation process are as follows: because the conveying height exceeds 100m, the gravitational potential energy of the concrete is converted into power in the falling process of the conveying pipe, huge impact force is generated when the concrete meets a control valve positioned in the middle, and the adopted valve is a gate valve, so that the gate valve can be damaged or blocked under the huge impact, the gate valve cannot be opened or closed subsequently, and the concrete is blocked in the pipeline; particularly, in the conveying stage before the pipe is full, concrete is not buffered and blocked in the discharging process in the pipe, the concrete is directly impacted and hit on the control valve, huge impact and shaking are generated, severe impact is generated on the conveying pipe support, the stability and the reliability of the conveying pipe support are influenced, the pipe support can fall off due to long-time fatigue impact, and further potential safety hazards are brought. Therefore, the buffer device is needed to buffer the concrete blanking process, and further the impact kinetic energy of the concrete in the falling process is reduced.

But this type of buffer structure can't be applicable to roller compacted concrete, because roller compacted concrete self mobility is poor, if set up the helical blade structure again inside the pipeline, then can cause the jam of conveyer pipe, and then influence follow-up normal transportation process.
CN 108265982 a discloses a concrete conveying device and an application and construction method thereof, wherein a plurality of sections of slide pipes and arc pipes are arranged to be in transition and alternate connection, so as to achieve the buffering effect. However, they are also not suitable for roller compacted concrete with poor flowability, since roller compacted concrete is prone to clogging in the area of the curved pipe.
