Description
Technical Field

Background
With the continuous development of projects such as traffic construction, development and utilization of water conservancy and ocean resources and the like, river-crossing, sea-crossing and other wading buildings are largely built, and the problem of life-span safety maintenance in project operation is more obvious. Wherein, the buried depth under the soil layer becomes shallow due to the washing of water flow and wave flow on the underwater structure foundation (such as bridge piers, pile groups and the like), which brings typical potential safety hazards of unstable structure or damage and the like. In order to reduce the local scouring of the foundation of the structure, timely scouring protection of the structure is one of important work for maintaining engineering safety.
The stone throwing protection is a common measure for scouring protection, and has the advantages of convenience for local materials, convenience for emergency rescue, simplicity and convenience in construction, obvious protection effect and the like. According to the research result, the riprap material with reasonable thickness and fineness and gradation has better protection effect than the broken stone material with uniform size, and the riprap material with the mixed thickness can construct a stable coarsening layer under the action of water flow, thereby achieving the purpose of reducing scouring.
If the construction method of the riprap is improper, the protection is difficult to realize. When the riprap is thrown above the water surface, the position deviation exists between the riprap starting point and the falling bed target point due to the migration effect of water flow on riprap particles, and the riprap is difficult to accurately fall into the target position. To overcome this difficulty, many engineers invented a throwing device for throwing stones, the main components of which are an inclined chute, a vertical chute or a vertical carrier box. The principle of the device is mainly that the flint is slid downwards to a preset position through the chute barrel.
Obviously, the construction method of sliding the riprap down to the preset position through the chute is suitable for the riprap with single grain diameter. However, for the riprap with the coarse and fine particle grading, due to the influence of gravity in the process of particle gliding, the downward gliding speeds of riprap particles with different particle sizes are different, and finally the riprap particles falling to the appointed position may form a coarse and fine layer, which is not consistent with the riprap material which is originally designed and is uniformly mixed with particles of all levels, and the expected scouring protection effect cannot be achieved.
In view of the above problems, the present designer is based on practical experience and professional knowledge that are abundant years after engineering application of such products, and is matched with the application of theory, and actively makes research and innovation to design a device for uniformly throwing the multi-stage mixed and dispersed particles of the stone thrower for underwater protection, so that the uniformly mixed stone thrower is lowered to a designated position around a pier (or a pile) by using a telescopic element, construction accuracy is improved, and uniformity of the mixed stone thrower is ensured.
