TECHNICAL FIELD

[0002] In the construction of a concrete face rockfill dam, the slope surface of the cushion material is a key construction part, and the quality thereof is directly related to the operation safety of the face slab and the dam body. Currently, common slope fixing methods mainly include slope rolling mortar slope fixing, extrusion type concrete side wall slope fixing, and turnover mold slope fixing.

[0003] The extrusion type concrete side wall slope fixing is performed by first constructing the extrusion type concrete side wall and then filling the dam. Due to the transportation of the concrete material, a concrete mixer truck is generally used. In order to meet the transportation requirements of the concrete mixer truck, the slump of the concrete is generally not too small. Influenced by this, in the extrusion process of the side wall, the problems of slow forming speed of the side wall, poor forming effect, large consumption of additives, and large workload of defect treatment in the later period are easily caused. The turnover mold slope fixing technology still largely relies on manual operation, has low mechanization degree, and has poor construction efficiency, and is easily disturbed by on-site operation. The slope rolling mortar slope fixing is a technology of performing mortar paving after the filling, preliminary compaction, slope repairing, and slope rolling of the cushion material.
