Examples
Debris flow (also called landslide-debris flow or particle type debris flow) is a widely existing geological phenomenon, and is a multiphase fluid consisting of a large amount of solid particles, a small amount of water medium and gas, and can rapidly flow on a valley or a slope under the driving of gravity and the like. The debris flow has the characteristics of high kinetic energy and strong destructive power, and is often converted into the debris flow with stronger impact property in the earthquake-triggered collapse or landslide. The damage to the infrastructure such as mountain roads, bridges and the like is great, and the highway and railway engineering is mostly destroyed in the forms of road blockage, roadbed destruction, pier breakage and the like.
Based on this, this application provides a gear structure, and it mainly leads the debris stream and blocks the debris stream combination, changes the moving trajectory of debris stream, leads the both sides of debris stream and discharges. The following detailed description is made with reference to the accompanying drawings.
referring to fig. 1, a gear structure 100 for protecting against a flow of slope debris is provided in an embodiment of the present application. The gear structure 100 includes a first anti-slip group 110, a first soil guard plate 120, a second anti-slip group 130, a second soil guard plate 140, a buffer layer 150, a vegetation soil layer 160, and a drainage groove 170.
The first anti-skid group 110 includes a plurality of first anti-skid piles 111 arranged at intervals, the plurality of first anti-skid piles 111 are arranged in a row, and the first anti-skid piles 111 are buried in bedrock of the side slope. The first anti-slide pile 111 is buried in bedrock, and the bedrock is a stable rock stratum and is not easy to slide. In some embodiments, the first anti-slide pile 111 extends into the underlayer rock stratum to a necessary effective anchoring depth, and is a support for the original slope soil layer and the strong weathering rock stratum, so as to ensure that the instability damage of the original slope soil layer and the strong weathering rock stratum is not caused under the action of strong shock. For those skilled in the art, the effective anchoring depth is actually determined by the particular engineering.
in some embodiments, the first anti-slide pile 111 extends above the ground by a height of 5-8 m (the specific height is determined according to the calculated volume of the debris flow).
Referring to fig. 2-3, the first soil blocking plate 120 is disposed between adjacent first anti-slide piles 111 for filling gaps between the first anti-slide piles 111 extending out of the ground, and the first soil blocking plate 120 and the first anti-slide piles 111 form an integral composite retaining structure together, so as to prevent leakage of debris flow and facilitate integral interception and blocking of the debris flow.
In some embodiments, the first retaining plate 120 and the first anti-slide pile 111 are formed by pouring steel bars and concrete together. When pouring, a pouring cavity is formed by enclosing the mould, a steel bar is reserved in the pouring cavity, then concrete is poured into the pouring cavity, and a first anti-slide pile 111 and a first soil retaining plate 120 are formed after concrete curing is completed. The first anti-slide pile 111 and the first soil retaining plate 120 share the impact of blocking the flow of debris. Since the first soil guard plate 120 does not need to be deeply inserted into the soil body or the bedrock, it is low in construction cost. In addition, because both sides of the first anti-slide piles are respectively connected with the two first anti-slide piles 111, the stability is relatively high.
Referring to fig. 4, the second anti-slide group 130 includes a plurality of second anti-slide piles 131 arranged at intervals, the plurality of second anti-slide piles 131 are arranged in a row, and the second anti-slide piles 131 are buried in bedrock of the slope. The second anti-slide pile 131 is buried in bedrock, which is a stable rock stratum and is not easy to slide.
In some embodiments, the second anti-slide pile 131 extends into the underlayer rock stratum to a necessary effective anchoring depth, and is a support for the original slope soil layer and the strong weathering rock stratum, so as to ensure that the instability damage of the original slope soil layer and the strong weathering rock stratum is not caused under the action of strong shock. For those skilled in the art, the effective anchoring depth is actually determined by the particular engineering.
An included angle formed between the length direction of the second anti-slip group 130 away from the side slope and the length direction of the first anti-slip group 110 away from the side slope is an obtuse angle. That is to say the first plurality of anti-slide studs 111 and the second plurality of anti-slide studs 131 are herringbone in a planar arrangement. Illustratively, the obtuse angle is 120-160 °.
The second retaining plates 140 are disposed between the adjacent second anti-skid piles 131. The second retaining plate 140 and the second anti-slide pile 131 form an integral composite retaining structure together, so that leakage of debris flow is prevented, and the debris flow is blocked integrally.
in some embodiments, the second retaining plate 140 and the second slide pile 131 are formed by pouring steel bars and concrete together. When pouring, a pouring cavity is formed by enclosing the mould, a steel bar is reserved in the pouring cavity, then concrete is poured into the pouring cavity, and the second slide-resistant pile 131 and the second soil baffle 140 are formed after concrete curing is completed. The second anti-slide pile 131 and the second retaining plate 140 share the impact of blocking the flow of debris. Since the second soil guard plate 140 does not need to be deeply inserted into the soil body or the bedrock, it is low in construction cost. In addition, since both sides thereof are connected to the two second anti-slide piles 131, respectively, it is also stable.
The debris flow sliding under the action of the strong shock is gathered and moves towards the gear structure 100, and the movement track of the debris flow is changed after the debris flow meets the first anti-slide pile 111, the first retaining plate 120, the second anti-slide pile 131 and the second retaining plate 140.
In a specific arrangement, the buffer layer 150 is disposed on the side of the first anti-slide pile 111, the first retaining plate 120, the second anti-slide pile 131, and the second retaining plate 140 close to the slope. The cushioning layer 150 is capable of absorbing energy through deformation to reduce the direct impact of debris flow on hard retaining work such as pilings.
In some embodiments, the cushioning layer 150 may be made of one or more of aluminum foam, PVC foam, or polyurethane foam. Foamed aluminum, PVC foam or polyurethane foam are all buffer materials with low density and strong impact absorption capacity, and can better absorb the impact energy of debris flow.
in a specific arrangement, the vegetation soil layer 160 is disposed on a side of the buffer layer 150 close to the side slope. In some embodiments, the vegetation soil layer 160 may be formed by stacking vegetation bags. Wherein, the planting bag comprises planting soil and plant seeds. The vegetation soil layer 160 can play a role in beautifying the environment, and the integrity of the side slope can be improved by the plant root system. In addition, the buffer layer 150 and the vegetation soil layer 160 adjacent to the first anti-slide pile 111 and the first soil retaining plate 120 can effectively dissipate the impact load of the debris flow and reduce the impact of the debris flow on the first anti-slide pile 111 and the first soil retaining plate 120.
With reference to fig. 1, in a specific arrangement, the guiding groove 170 includes a first groove body 171 and a second groove body 173, the first groove body 171 and the second groove body 173 are disposed between the slope and the vegetation soil layer 160, an extending direction of the first groove body 171 is consistent with a length direction of the first anti-sliding group 110, and an extending direction of the second groove body 173 is consistent with a length direction of the second anti-sliding group 130. In this case, the buffer layer 150 and the vegetation soil layer 160 are located on the groove walls of the grooves of the first groove body 171 and the second groove body 173, so that the debris flow with reduced impact kinetic energy is discharged to the lower part of both sides, that is, the debris flow moves along the extending direction of the first groove body 171 and the second groove body 173, and also moves from the height to the lower part. It will be appreciated that the slope of the groove bottoms of the first and second groove bodies 171, 173 may be varied as desired by those skilled in the art. Thus, the row guide groove 170 has a double-letter structure in a plane and a vertical plane.
the debris flow formed by the strong shock action is guided to the two sides by the drainage groove 170 and is discharged from the two sides of the drainage groove 170, so that manual or mechanical cleaning is facilitated.
In some embodiments, the first and second soil guard plates 120 and 140 are opened with water passing holes for water penetration. The water holes can be used for draining water, so that the erosion of water to the surface layer of the side slope is reduced, and the rock mass cracking is reduced.
The gear structure 100 obtained through the design can basically meet the requirements of gear of debris flow and the problem of improving the slope protection capability. However, the inventors have further improved the gear structure 100 in order to further improve the functions thereof.
traditional piece stream protection engineering structures such as stone blocking wall, stone blocking fence, stone blocking embankment are difficult to solve self stable structure problem under the macroseism effect, and especially the piece stream that forms under the macroseism effect has bigger scale and impact energy, and traditional "hard hitting hard" piece stream protective structure is very easily destroyed the inefficacy by powerful impact, and can't dredge the piece stream well, can't form effective protective capacities to the piece stream that produces under the macroseism. Meanwhile, instability of the slope soil body and the strongly weathered rock mass can be induced under the action of strong shock, the traditional debris flow protection engineering structure is shallow in embedment depth and limited in interception height, and the effects of supporting and retaining the slope soil body and the strongly weathered rock mass cannot be taken into consideration.
Referring to fig. 5, in some embodiments, the first anti-skid group 110 further includes a first concrete body 113 and a first retaining wall 115, the first concrete body 113 is disposed between the buffer layer 150 and the first anti-skid piles 111, and the first retaining wall 115 is disposed on the top of the first concrete body 113 and the first anti-skid piles 111.

Illustratively, the first concrete body 113 is formed by pouring a lightweight concrete body, so that the first concrete body 113 has a smaller extrusion force (has a smaller self-gravity) on the first slide-resistant pile 111, which is beneficial to the long-term use of the first slide-resistant pile 111.
In some specific embodiments, a first buffer 117 is disposed between the first concrete body 113 and the first anti-skid pile 111.

Illustratively, the second concrete body 133 is formed by pouring a lightweight concrete body, so that the second concrete body 133 has a smaller extrusion force (a smaller self-gravity) on the second slide pile 131, which is beneficial to the long-term use of the second slide pile 131.
