[0002] Concrete slope trowelling construction is most common in water conservancy slope protection construction, and the process of mechanical trowelling after concrete pouring is usually adopted to form a flat and solid slope surface, and the traditional construction mode usually comprises: laying a track on the slope surface, drawing a trowelling machine along the track by a winch, and sequentially completing the paving and trowelling of concrete, and the front end of the common trowelling device is provided with a spreading plate for initially spreading concrete, and the rear end is provided with a trowelling plate for final compaction and smooth surface.
[0003] However, in actual construction, the initial concrete laid under the slope surface often has uneven thickness, and when the trowelling machine advances, the spreading plate at the front end will continuously push the excess concrete higher than the design thickness forward, and these pushed concrete gradually accumulates in front of the spreading plate, forming a continuously increasing "concrete wedge", and as the equipment continues to advance, the volume of the accumulation body will become larger and larger, and finally it is easy to exceed the height or lateral accommodation range of the spreading plate, resulting in a large amount of concrete overflowing or spilling to the clean area behind which has been trowelled, which not only seriously damages the flatness and appearance quality of the completed surface, but also forces the construction to be interrupted and time-consuming and laborious rework cleaning.
[0004] At the same time, in order to deal with the accumulation, a plurality of workers often stand outside the slope or the unconstructed area and manually shovel the accumulated concrete with a shovel and other tools and rethrow it to the area to be paved, which is labor-intensive, low in construction efficiency, has safety hazards, and manual intervention cannot guarantee the uniformity of the second paving of concrete, finally affecting the overall quality and performance of the slope protection structure.
