Description

High-frequency mud-rock flow shore protection flow guiding structure Technical Field The utility model relates to the technical field of natural disaster prevention, in particular to a high-frequency debris flow shore protection diversion structure. Background At the same time of popularization of mountain railways and highways, because the mountain railways and highways span areas with complex geological and topographic conditions and fragile environments, and frequent debris flow disasters, the debris flow disasters easily cause huge damages and a series of economic losses to the embankments, the highways and the infrastructure along the lines, so that diversion trenches for guiding the trend of the debris flow are generally arranged to reduce the damage of the debris flow to surrounding basic environments as much as possible. At present, the existing diversion trench can only control the flow speed by controlling the trend of the mud-rock flow, but the mud-rock flow carries a large amount of solids such as silt, barren rock, trees and the like, and has larger impact force in the impact process, so that the impact on the bank is easy to cause the damage of the bank. Disclosure of utility model Based on the above, the utility model aims to provide a high-frequency mud-rock flow shore protection diversion structure so as to solve the technical problem that the conventional diversion trench can control the trend of mud-rock flow but can not effectively buffer the impact force of the mud-rock flow, so that a dike is easily damaged. In order to achieve the purpose, the high-frequency debris flow shore protection diversion structure comprises earth and stones and a protection assembly, wherein the protection assembly comprises a first protection mechanism and a second protection mechanism, the first protection mechanism comprises a fixed column, the upper end and the lower end of the fixed column are fixedly connected with two first steel cables, and a first blocking net is welded on the first steel cables. Through adopting above-mentioned technical scheme, two first steel cables pass through fixed column upper end and lower extreme fixed connection, provide firm support for first block, and first steel cable has higher intensity and toughness, can bear the huge pulling force that produces when the debris flow strikes. Further, the second protection mechanism comprises a second blocking net, second steel cables are welded on two sides of the second blocking net, and fixing anchors are arranged at two ends of the second steel cables. Through adopting above-mentioned technical scheme, the welding of second steel cable is in the both sides of second block, provides extra support and fixed action for the block, under the powerful impact force of mud-rock flow, only rely on the intensity of block self probably to be difficult to bear, and the existence of steel cable can strengthen the overall stability of block. Further, the second steel cables are provided with two groups, and each group of the second steel cables is uniformly provided with a plurality of second steel cables in a linear array at equal intervals. Through adopting above-mentioned technical scheme, the second steel cable sets up two sets of, and every group is the even a plurality of that sets up of linear array equidistance, and this kind of overall tensile strength of second protection mechanism has been strengthened in the overall arrangement, when the mud-rock flow impacted the second blocking with powerful impact force, and two sets of second steel cables can bear the pulling force jointly, with strength evenly dispersed to each steel cable. Further, the first blocking net and the second blocking net are composed of a plurality of metal rings, and a plurality of protection components are arranged on the inclined planes of the earth and the stone. Through adopting above-mentioned technical scheme, the metal ring has higher intensity and toughness, and first block and the second block that comprise a plurality of metal rings can bear great impact force. Further, a blocking groove is formed between the first blocking net and the second blocking net, and the cross section of the blocking groove is trapezoidal. By adopting the technical scheme, the cross section of the baffle groove is in a trapezoid shape, and the unique shape provides favorable conditions for sediment and solid matter deposition, so that the content of the solid matter in the debris flow is effectively reduced. Furthermore, a speed reducing groove is formed in the top of the earth and stone, and side walls are arranged on two sides of the inclined plane of the earth and stone. Through adopting above-mentioned technical scheme, when the mud-rock flow dashes down with high speed from the top, can at first contact with the cambered surface of reducing gear, the shape of cambered surface has changed the flow direction of mud-rock flow, makes its flow track take place to deflect, becaus
