In the description of the present application, "upper", "lower", "top", "bottom", orientation or positional relationship is based on the orientation or positional relationship shown in fig. 3, it being understood that these orientation terms are merely for convenience in describing the present application and for simplicity in description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present application.

In the description of the present application, referring to fig. 1, 2, and 4-7, the material flow is in the direction of arrow R. When the material flow is a debris flow, the direction indicated by the arrow R in the figure is the flow direction of the debris flow.

The term "connected" in the description of the present application may be directly connected or indirectly connected.

Before describing the embodiments of the present application, it is necessary to analyze the reasons of the prior art that the debris flow protection equipment has a long construction period and high protection cost and is difficult to repair quickly after being damaged, and a technical solution of the embodiments of the present application is obtained through reasonable analysis.

In the prior art, the protection and interception of debris flow are usually to build diversion canals and interception dams. The diversion channel and the interception dam usually directly intercept stones in the debris flow, the impact energy of the debris flow on the diversion channel and the interception dam is large, and the diversion channel and the interception dam directly intercept the stones in the debris flow and need to bear large impact load. Therefore, the construction requirements for the diversion canal and the interception dam are high, large construction equipment is usually required to enter the field for matched construction, the construction difficulty is high, the construction period is long, the construction cost is high, and accordingly the protection cost is high. The diversion trench and the interception dam are repaired by large-scale construction equipment, so that the diversion trench and the interception dam are difficult to repair quickly.

In view of this, the present embodiment of the application provides a protection apparatus, please refer to fig. 1 and fig. 2, the protection apparatus includes at least one protection assembly 700, and the protection assembly 700 includes a buffer pile group 1 and a protection net 2. The buffer pile group 1 comprises a plurality of buffer piles 11, each buffer pile 11 is partially located in a stable stratum at the bottom of a material flow channel, and the distance between every two adjacent buffer piles 11 is configured to enable the largest stones in the material flow to pass through between every two adjacent buffer piles 11. The protective net 2 is positioned at the back flow end of the buffer pile group 1, and the protective net 2 is configured to intercept material flow.

The protective apparatus of this application embodiment, on the one hand because the interval configuration between two adjacent buffer piles 11 is for making the biggest stone in the material stream can pass through between two adjacent buffer piles 11, when the material stream passes through buffer pile crowd 1, the stone in the material stream can collide with buffer pile 11 and strike, consume the impact energy of the stone in the material stream, but the stone can slow down to pass through between two adjacent buffer piles 11, buffer pile 11 can not intercept the stone, consider material stream incoming material direction and spatial condition, develop buffer pile 11 planar arrangement, to reach and reduce the impact force of material stream to buffer pile 11, ensure that destructive power is less relatively, correspondingly, the required shock resistance of buffer pile 11 can be less relatively, can reduce the cost of manufacture of buffer pile 11 to a certain extent. On the other hand, due to the energy consumption of the buffer piles 11 to the stones in the material flow, the impact energy of the stones in the material flow to the protection net 2 is reduced, so that the protection net 2 can intercept the material flow passing through the buffer pile group 1 more effectively. Furthermore, the protective apparatus of this application embodiment is earlier through the impact energy of 11 consumption stones of buffering stake, and rethread protection network 2 intercepts, and for the mode of direct interception, buffering stake 11 and protection network 2 are less because the load that receives of the impact of material flow, and the laying of buffering stake 11 and the net-forming process of protection network 2 all need not the main equipment to enter the field, and for diversion canal and interception dam, the construction degree of difficulty is less, and construction cycle is shorter, and the protection cost is less. Even if the buffer piles 11 and the protection net 2 are damaged, the buffer piles 11 and the protection net 2 can be repaired more quickly because the construction period for laying the buffer piles 11 and forming the net is short and the construction conditions are simple. The protective equipment provided by the embodiment of the application can better intercept and protect the debris flow with larger impact energy under the condition of high and steep terrain by consuming the rock impact energy first and then intercepting.

It should be explained that material flows through the buffer pile group 1, stones in the material flow collide with the buffer piles 11 to consume impact energy, and since the largest stones can pass through between two adjacent buffer piles 11, all kinds of stones in the debris flow can basically pass through between two adjacent buffer piles 11 without being intercepted by the buffer piles 11, so that impact force of the stones on the buffer piles 11 is reduced while impact energy of the stones is consumed.

It should be explained that what was blocked in the debris flow is given first place to the stone, may have still been mingled with other by the interception thing such as trees, and wherein the impact energy of stone is great for the impact energy of other by the interception thing, and the destructive power is stronger, consumes the impact energy of stone in the debris flow through buffering stake crowd 1, can reduce the destructiveness of debris flow comparatively effectively, is favorable to protection network 2 to carry out comparatively effectively interception to the debris flow.

It should be explained that a stable formation generally refers to a formation below the residue of a material stream. Taking the debris flow as an example, the debris flow usually occurs many times at the place where the debris flow occurs, and the debris will be accumulated at the bottom of the flow channel every time the debris flow passes through the flow channel, and the debris is generally loose and difficult to fix the buffer pile 11. The stratum below the residue is the original foundation stratum of the flow channel before the debris flow passes through, and the stratum is relatively stable and is not loose like debris flow residue, so that the buffer pile 11 can be well fixed, the buffer pile 11 is prevented from being separated from the stratum in the impact process of the stone, and the buffer pile 11 can effectively consume the impact energy of the stone.

It can be understood that, referring to fig. 1 and fig. 2, since the protection net 2 is located at the back flow end of the buffer pile group 1, the material flow flows through the buffer pile group 1 first and then flows through the protection net 2.

It can be understood that the protective net 2 is convenient to disassemble and assemble, can be repeatedly used in disaster frequent areas, and is convenient for quickly propelling post-disaster reconstruction work.

It should be noted that, when the debris flow flows through the flow channel, the density of the stones in the debris flow is high, and the stones in the debris flow generally flow at the bottom of the flow channel, so that the bottom of the protection net 2 is impacted strongly.

In one embodiment, the material stream may be a debris stream. It can be known that when a debris flow disaster occurs, water flow is wrapped by stones and has larger impact energy.

In an embodiment, referring to fig. 2 to 7, the distance between two adjacent buffer studs 11 may be a distance D1 between two adjacent buffer studs 11 along the two sides of the material flow path.

It should be noted that, referring to fig. 3 and 7, the direction of the material flow path on both sides is the direction indicated by the arrow C in the figure.

In one embodiment, the buffer piles 11 may be made of steel rails.

In one embodiment, the buffer piles 11 may be made of steel piles.

It can be understood that the materials of the steel rail, the steel pile or the reinforced concrete are convenient to select, and the materials are cheap and can be selected according to actual conditions on site.

It will be appreciated that as the debris flow flows in the flow channel, the impact energy of the debris flow is generally less the closer it is to the side wall 3 of the flow channel. In view of this, in an embodiment, referring to fig. 4 to fig. 6, the buffer pile group 1 is in a preset shape, the outer boundary of the preset shape includes a large end boundary 100, a small end boundary 200, and a side boundary 300, the small end boundary 200 is away from the protection net 2, the large end boundary 100 faces the protection net 2, and the side boundary 300 is located between the large end boundary 100 and the small end boundary 200; the distance D2 between the position of the buffer posts 11 on the side boundary 300 and the corresponding runner sidewall 3 gradually decreases in the flow direction of the material flow. With such a structure, the direction from the small end boundary 200 to the large end boundary 100 is the flow direction of the debris flow, the debris flow flows from the small end boundary 200 with the preset shape to the large end boundary 100 with the preset shape, and after the debris flow impacts the buffer pile 11 on the small end boundary 200, the water flow and the stones in the debris flow are distributed towards the side walls on both sides of the flow channel. On the one hand, the impact energy of the debris flow can be greatly consumed, on the other hand, the impact energy of the stones is consumed by the buffer piles 11 on the two sides, and the possibility that the buffer piles 11 far away from the side wall 3 of the flow channel are damaged due to excessive impact of the debris flow is reduced.

It should be noted that the large end boundary 100 and the small end boundary 200 are relative, and the large end boundary 100 is larger than the small end boundary 200 in the direction along both sides of the flow passage.

In one embodiment, a plurality of buffer piles 11 are symmetrically arranged along the direction of two sides of the flow passage.

It is understood that the outer boundary of the predetermined shape is surrounded by some of the buffer piles 11, and other buffer piles 11 are located inside the outer boundary.

In an embodiment, referring to fig. 4, the predetermined shape is a triangle, as shown by the dotted line in the figure, the three points of the triangle are all provided with the buffer piles 11, the small end boundary 200 is one of the points of the triangle, and the large end boundary 100 is the side line corresponding to the point. The remaining two edges of the triangle are side boundaries 300.

It will be appreciated that for a point, it corresponds to a dimension along both sides of the flow channel that is infinitely close to zero. I.e. the size of the triangle's cusps in the direction of the two sides of the flow channel is infinitely close to zero.

In one embodiment, referring to fig. 5, the predetermined shape is a trapezoid, as shown by the dotted line, the large end boundary 100 is the longer side line of the two parallel lines of the trapezoid, the small end boundary 200 is the shorter side line of the two parallel lines of the trapezoid, and the side boundary 300 is the waist line of the trapezoid.

In an embodiment, referring to fig. 6, the predetermined shape is an arch, as shown by dotted lines in the figure, the outer boundaries of the arch are provided with the buffer piles 11, the small end boundary 200 is a point farthest from the protection net 2, the buffer piles 11 are provided at the point, and the rest of the buffer piles 11 are located between the buffer piles 11 at the small end boundary 200 and the protection net 2. The large end boundary 100 is a side line corresponding to an arcuate arc. The side boundary 300 is an arcuate arc on both sides of the point farthest from the protection net 2.

It is understood that the dimension in the direction of both sides of the flow path at the point farthest from the protection net 2 is infinitely close to zero.

In one embodiment, referring to fig. 7, the predetermined shape may be a rectangle, as shown by the dotted line.

In one embodiment, all the buffer piles 11 may be arranged in a single row in the direction of both sides of the flow passage.

In one embodiment, the depth of the buffer piles 11 in the stable formation is greater than or equal to two times of the diameter of the largest rock, and the height of the buffer piles 11 exposed out of the ground is greater than or equal to 0.5 times of the diameter of the largest rock. Structural style like this for buffer pile 11 can insert in the stable stratum comparatively firmly, reduces buffer pile 11 and breaks away from the possibility in the stable stratum under the impact of stone. The height setting that buffer pile 11 exposes the stratum for buffer pile 11 can consume the impact energy of stone comparatively effectively.

In one embodiment, the depth of the buffer piles 11 embedded in the stable stratum is greater than or equal to 4 meters.

In one embodiment, the height of the buffer piles 11 exposed out of the ground is greater than or equal to 2 meters.

In one embodiment, the distance between two adjacent buffer piles 11 is 1-2 times the diameter of the largest stone block. Structural style like this makes the stone in the mud-rock flow can not blocked by buffering stake 11 and live, and the distance between the adjacent buffering stake 11 of on the other hand should not be too big, increases the probability that stone and 11 impact collisions of buffering stake, makes the impact energy of stone can obtain consuming comparatively effectively. The situation that stones directly pass through between two adjacent buffer piles 11 without impacting and colliding with the buffer piles 11 is avoided.

In one embodiment, the bottom of the flow path for the material flow is drilled. For example, the material stream may be a debris stream. The drill hole is drilled into the stable formation to a depth greater than or equal to twice the diameter of the largest stone block, typically greater than 4 meters. And embedding the buffer pile 11 into the drill hole, and pouring mortar into the drill hole for sealing the hole.

It can be understood that the farther the buffer piles 11 are from the protection net 2, the greater the impact energy of the rock encountered by the buffer piles 11, the farther the buffer piles 11 are from the protection net 2, the energy of the rock encountered by the buffer piles 11 has not been consumed, the greater the impact energy of the rock, and the stronger the destructive power of the buffer piles 11. In one embodiment, the height of the buffer piles 11 exposed to the ground is gradually increased along the material flow direction. Like this, keep away from protection network 2 more, buffer pile 11 exposes the height on ground the less, and the stone strikes buffer pile 11 after the possibility of crossing from buffer pile 11 top is bigger, and under the great condition of impact energy of stone, the stone can cross from the top of buffer pile 11, or passes through from between two adjacent buffer piles 11, can enough make buffer pile 11 consume the stone impact energy, can avoid buffer pile 11 to damage because of the impact of stone as far as possible.

In one embodiment, the height of the buffer piles 11 farthest from the protection net 2 exposed to the ground may be 0.5 times the diameter of the largest stone block.

In one embodiment, referring to fig. 2, the height of the buffer piles 11 exposed to the ground may be equal.

In one embodiment, referring to fig. 3, two sides of the protection net 2 are connected to the corresponding runner sidewalls 3, and the bottom of the protection net 2 is connected to the buffer piles 11. Structural style like this, because buffer pile 11 inserts stable ground, buffer pile 11 itself is comparatively firm, and the bottom and the buffer pile 11 of protection network 2 are connected, can be better connect fixedly to the bottom of protection network 2. The protective net 2 is arranged on the side walls 3 of the flow channel at two sides of the flow channel, the height of the protective net 2 can be set to be almost equal to the height of the side walls 3 of the flow channel, and the protective net can be well suitable for debris flow protection of high and steep terrains.

In one embodiment, referring to fig. 3, the protection net 2 includes a main rope 21, a cross rope 22 and a suspension rope 23. The main cable 21 is positioned at the back flow end of the buffer pile group 1, and two ends of the main cable 21 are connected with the corresponding runner side walls 3. The transverse cable 22 is positioned at the back flow end of the buffer pile group 1, the transverse cable 22 is positioned below the main cable 21, and two ends of the transverse cable 22 are connected with the corresponding flow channel side walls 3. The sling 23 is cross-connected with the transverse cable 22, one end of the sling 23 is connected with the main cable 21, and the other end of the sling 23 is connected with the buffer pile 11. In such a structure, the protective net 2 is formed by the main ropes 21, the transverse ropes 22 and the slings 23, the two ends of the main ropes 21 and the two ends of the transverse ropes 22 are connected with the runner side walls 3, and the slings 23 are connected with the buffer piles 11, so that the protective net 2 is installed in the runner of material flow.

It will be appreciated that the uppermost row of holes is surrounded by the main rope 21, cross rope 22 and suspension rope 23. The lowest mesh is formed by the surrounding of the bottom of the flow passage, a sling 23 and a transverse cable 22. The mesh closest to the runner side wall 3 is formed by surrounding the main rope 21, the sling 23, the cross rope 22 and the runner side wall 3, or is formed by surrounding the sling 23, the cross rope 22 and the runner side wall 3. The rest meshes are surrounded by a sling 23 and a transverse cable 22.

In one embodiment, the main rope 21 has an impact resistance greater than or equal to 500KN, and the cross rope 22 and the suspension rope 23 have an impact resistance greater than or equal to 300 KN.

The impact resistance can be confirmed from the calculation results.

In one embodiment, the mesh openings can be the average particle size of the stone.

It will be understood that the pore size of the mesh is characterized by the size of the mesh, and that the pore size of the mesh is the average particle size of the stone, i.e. the stone having a diameter below the average particle size can pass through the mesh relatively smoothly. Stone blocks having a diameter larger than the average grain diameter are difficult to be intercepted by the protection net 2 through the meshes.

In one embodiment, the mesh opening size is greater than or equal to 1 meter.

In an embodiment, referring to fig. 3, the protection net 2 further includes T-shaped cable buckles 24 and cross-shaped cable buckles 25. The main rope 21 and the sling 23 are connected through a T-shaped rope buckle 24, and the transverse rope 22 and the sling 23 are connected through a cross-shaped rope buckle 25. In such a structure, the sling 23 and the main rope 21 can be fixedly connected through the T-shaped cable buckle 24, the transverse rope 22 and the sling 23 can be fixedly connected through the cross-shaped cable buckle 25, the main rope 21, the transverse rope 22 and the sling 23 cannot slide due to the impact of debris flow, and the mesh aperture of the protective net 2 is stable. The main ropes 21, the transverse ropes 22 and the suspension ropes 23 can be conveniently disassembled and assembled through the T-shaped cable buckles 24 and the cross-shaped cable buckles 25, so that the protective net 2 can be conveniently formed by netting on site, and the rapid repair of the protective net 2 is realized. And the aperture of the mesh is convenient to adjust.

It can be understood that even if the protection net 2 is damaged by impact, the protection net 2 may be rebuilt with ropes, which enables repair to be performed relatively quickly.

It will be appreciated that the specific construction of the T-shaped cord lock 24 and cross-shaped cord lock 25 is conventional in the art of cord connection and will not be described in detail.

In one embodiment, the main cable 21 and the sling 23 are hinged by a T-shaped buckle 24, and the cross cable 22 and the sling 23 are hinged by a cross-shaped buckle 25.

In one embodiment, the number of steel strand wires of the transverse cable 22 is greater than or equal to 3.

In one embodiment, the number of steel strand wires in the sling 23 is greater than or equal to 3.

When the main rope 21 is connected to the corresponding runner sidewall 3, referring to fig. 8, the main rope 21 is inserted into the rope groove of another heart lock ring 400, and the rope clip 500 is used to lock the part of the main rope 21 passing through the heart lock ring 400 and the part of the main rope 21 not entering the heart lock ring 400. In this way, the main cable 21 and the anchor cable 33 are connected by two heart lock rings 400, thereby achieving the connection of the main cable 21 to the corresponding runner sidewall 3.

It is to be understood that the connection between the main cable 21 and the anchor cable 33 is not limited to the chicken-lock loop connection, and the main cable 21 and the anchor cable 33 may be directly connected.
