Description

Fog gun machine mounting platform fixed on roller compacted concrete dam straight face template Technical Field The utility model relates to the technical field of water conservancy and hydropower construction, in particular to a fog gun machine mounting platform fixed on a roller compacted concrete dam straight face template. Background The roller compacted concrete dam is constructed by adopting layered unloading, paving and rolling modes, and the bin surface of the roller compacted concrete should be kept moist in the construction process. Especially, when constructing under strong wind, dry, high temperature climates, need to take the storehouse face spraying measure, build the microclimate of storehouse face and prevent the concrete surface moisture from scattering, guarantee the construction quality of combining between the roller compacted concrete layers. The conventional warehouse surface spraying moisturizing measures comprise a movable sprayer, a spraying vehicle, a manual hand-held hair-flushing gun and the like, and as the roller compacted concrete dam is gradually increased along with construction, the dam is more narrowed, and the spraying measures have different degrees of progress and quality influence on dam construction. When the movable sprayer is used for spraying and moisturizing dam construction, a plurality of spraying machines are arranged in the warehouse in advance, the movable spraying machine is used for covering the warehouse surface, the mode has the problems that the equipment is heavy in weight, the movable spraying machine moves on the rolled strip, construction quality is possibly damaged, car sinking accidents occur and the like, when the spraying machines are used for spraying, the spraying machines are opened into the warehouse surface or the mouth of the fog gun machine is sprayed into the warehouse in front of the warehouse, the spraying machines occupy the warehouse surface space, normal construction of concrete transportation vehicles is affected, particularly when the warehouse surface is large in size, the effective spraying coverage is seriously insufficient, the manual hand-held hair punching gun can only play an auxiliary spraying effect at present, the spraying effect is far lower than that of mechanical spraying, and the construction requirement of the warehouse surface cannot be covered in a large area.
