Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, and specifically relates to a flexible protective barrier mechanism and construction method for debris flow geological disasters. Background Technology

[0002] Debris flow is a special type of fluid composed of mud, rocks, and water, falling between sediment-laden water flow and landslide. It is characterized by its sudden occurrence, short duration, strong impact, and significant destructiveness.

[0003] Currently, the main measures for preventing and controlling debris flows are to construct stepped sand-blocking dams and flexible protective nets in the upper reaches of the valley to intercept loose soil and rocks, thereby reducing the speed of the debris flow, decreasing the impact force of the debris flow, and mitigating the loss of life and property to a certain extent.

[0004] In practical applications, during the movement of dilute debris flows, large rocks are mainly concentrated at the front end of the debris flow. Flexible protective nets are used to block the large rocks at the front end, allowing the subsequent water and sediment to be washed away.

[0005] For example, a solid with a volume of 100 mm, a mass of 2600 kg, and a speed of 10 m / s can have a kinetic energy of 20000 kJ. Therefore, flexible protective nets need to provide significant resistance to block debris flows. However, due to stress concentration at the impact points, the flexible protective nets are easily torn, causing them to fail and resulting in poor interception capabilities.

[0006] Therefore, how to solve the defects in the above-mentioned technical solutions has become one of the urgent problems to be solved in the field of water conservancy engineering technology. Summary of the Invention

[0047] Furthermore, the outer buffer, the inner buffer, and the buffer pads disposed within the two sets of buffers combine to form a two-stage buffer mechanism.

[0048] Optionally, the buffer rod includes a buffer sleeve.

[0049] The buffer sleeve is provided with a blocking end.

[0050] The cavity of the buffer sleeve is divided into two sets of chambers by blocking the end.

[0051] These are the first chamber and the second chamber, respectively.

[0052] The chamber closest to the connector is the first chamber.

[0053] The chamber furthest from the connector is the second chamber.

[0054] Both chambers are filled with fluid.

[0055] Furthermore, the size of the two sets of chambers can be adjusted according to the blocking end, and the blocking end is provided with a channel;

[0056] The blocking end is mounted on the connecting rod.

[0057] Furthermore, the connecting rod is provided with a connecting seat integrally formed therewith.

[0058] Furthermore, a sealing gasket is provided between the top end face of the buffer sleeve and the connecting seat;

[0060] Furthermore, the support rod is connected via the connector, and the connector is equipped with an installation buckle.

[0061] Furthermore, the outer wall of the support rod is secured by a fastener.

[0062] A control valve is installed on the end face of the strut.

[0063] Optionally, construction methods for flexible protective barriers for debris flow geological hazards include:

[0064] Step 1: Determine parameters such as pile foundation axis length, pile foundation width, and height based on the actual terrain conditions;

[0065] Step 2: According to the design protection standards of the prevention and control project, determine the installation positions of the two sets of buffer plates, install the buffer plates on the top end face of the pile foundation, then install the stainless steel plate, and pour concrete on the stainless steel plate to form a reinforcing plate.

[0066] By opening a positioning hole on the second anchor plate connected to the reinforcing plate, the steel anchor rod is placed in the positioning hole, and concrete is poured at the same time. Similarly, the other end of the steel anchor rod is installed on the first anchor plate.

[0067] Install another set of buffer plates in the same manner;

[0068] The distance between the front and rear sets of buffer plates is 'a', and L≤a≤3L, 50cm≤L≤350cm;

[0069] The buffer plate is laid at a height of H1 on the pile foundation, where H1 = H2 - H3 + h, H2 is the height of the pile foundation, H2 is the corresponding depth of the discharge outlet, and h is the reserved safety freeboard, and h does not exceed 0.65m.

[0070] Step 3: Determine the required thickness of the pile foundation and the required thickness of the rectangular groove through sampling tests, and open the rectangular groove on the end face of the pile foundation;

[0071] Step 4: Install the adjustment mechanism. Install the drive component of the adjustment mechanism on the pile foundation, with the third and second gears of the adjustment mechanism located in the rectangular groove, while the first gear of the adjustment mechanism extends out of the rectangular groove and is located in the mounting base.

[0072] A groove is formed on the end face of the mounting base so that the adjustment plate can pass through the groove, enter the interior of the mounting base, pass through the mounting base, and extend to the outside;

[0073] The frame is mounted at an angle on the end face of the adjustment plate that extends outward through the mounting base;

[0074] Step 5: Install the flexible protective netting;

[0075] The reinforcing bars and the anchor rods for the first connecting ring used to connect the wire ropes are installed on the reinforced end. Then, concrete is poured to complete the installation of the first connecting ring anchor rods. The first connecting ring anchor rods need to be installed on the reinforced ends of the four end faces of the frame, on the top, bottom, left, and right.

[0076] Then, the wire rope is passed through the first connecting ring and wrapped around to form a connecting ring. The tail of the wire rope is then fixed to the wire rope with reinforcing fasteners to form a second connecting ring, thus completing the connection between the first and second connecting rings.

[0077] Similarly, the assembly of multiple sets of connecting rings is completed in sequence, thereby realizing the installation of multiple sets of wire ropes;

[0078] Step Six: Complete the connection between the flexible protective net and the steel wire rope, and fix the flexible protective net by using the buckles set at the four corners of the anchoring connector;

[0079] The flexible protective net is woven from at least three steel hinge ropes, and the steel hinge ropes are made of at least four 3mm diameter steel wires. The inscribed circle diameter of the flexible protective net mesh is 250mm, and the length-to-short diameter ratio of the flexible protective net mesh is less than 2.

[0080] In summary, the beneficial effects of this invention are:

[0081] This invention adds an adjustment mechanism connected to the flexible protective net. When a debris flow arrives, a sensor assembly on the flexible protective net detects that the impact force of the debris flow exceeds a pre-set value. This triggers a drive assembly, which in turn drives a third gear to rotate. This, in turn, rotates the first gear and its shaft by a corresponding angle. This, in turn, causes an adjustment plate on the first gear shaft to rotate by a corresponding angle, which in turn rotates the flexible protective net on the frame by a corresponding angle. This allows the surface of the flexible protective net to rotate when impacted by a debris flow, effectively preventing stress concentration in a single location and preventing tearing of the net.

[0103] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Although exemplary embodiments are disclosed in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to facilitate a thorough understanding of the present invention and to fully convey the inventive concept to those skilled in the art.

[0104] In the description of this specification, the references to terms such as "certain embodiments," "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0105] In this invention, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; the term "multiple" refers to two or more unless otherwise explicitly defined. The terms "install," "connect," "link," and "fix" should be interpreted broadly. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; "link" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0106] To solve the above technical problems, such as Figure 1-8 As shown, this embodiment provides a flexible protective barrier mechanism 100 for debris flow geological disasters, including a pile foundation 10 set in a mountain valley. The pile foundation 10 adopts a reinforced concrete structure, and a rectangular groove 101 is provided on the pile foundation 10. An adjustment mechanism for adjusting the flexible protective net assembly 40 is provided in the rectangular groove 101.

[0107] Furthermore, the adjustment mechanism includes a mounting base 502, which is fixedly installed on the top end face of the pile foundation 10;

[0108] The adjustment mechanism also includes a drive component 501, which drives the gear transmission component 503 to adjust the angle of the adjustment plate 506.

[0109] Furthermore, the drive assembly 501 is preferably a motor. The drive assembly 501 passes through the pile foundation 10 and the mounting base 502 and is connected to the rotating shaft 507. At least one set of third gears 5033 is mounted on the rotating shaft 507. The third gears 5033 mesh with the second gear 5032 and mesh with the first gear 5011 through the second gear 5032.

[0110] Furthermore, the first gear 5031 is mounted on the first gear shaft, and adjustment plates 506 are respectively mounted on both ends of the first gear shaft.

[0111] In this embodiment, those skilled in the art should understand that the first gear, the second gear, and the third gear combine to form a gear transmission assembly. By activating the drive assembly 501, the third gear is driven to rotate, which in turn drives the first gear and the first gear shaft to rotate, thereby causing the adjustment plate 506 disposed on the first gear shaft to adjust its angle.

[0112] Furthermore, a rectangular groove 101 is formed on the end face of the pile foundation 10.

[0113] The mounting base 502 has a groove on its end face so that the adjustment plate 506 can pass through the groove, enter the interior of the mounting base 502, pass through the mounting base 502, and extend to the outside.

[0114] Furthermore, an inclined frame 504 is provided on the adjustment plate 506 extending away from the end face of the mounting base 502 of the gear transmission assembly, and a reinforcing end 403 is installed on both the side end face and the bottom end face of the frame 504, and the reinforcing end 403 is formed by cast reinforced concrete.

[0115] In this embodiment, those skilled in the art should understand that before pouring, the reinforcing bars and the anchor rods for connecting the first connecting ring 406 of the wire rope are installed on the reinforcing end 403, and then the connection between the reinforcing end 403 and the first connecting ring 406 is achieved through the construction concrete.

[0116] Furthermore, the first connecting ring 406 is connected to the second connecting ring, and the second connecting ring is fixed by a reinforcing fastener 405. The second connecting ring is formed by wrapping a reinforcing steel wire rope 401 around it and fixing it at the tail end by a reinforcing fastener 405.

[0117] Furthermore, the flexible protective net 402 is fixedly connected to the reinforcing steel wire rope 401 through the anchoring connector 404, thereby realizing the connection between the frame 504 and the flexible protective net 402. The four corner ends of the anchoring connector 404 of the frame 504 are provided with buckles, and the flexible protective net 402 is fixedly connected through the buckles. The anchoring connector has a size of not less than 320*180mm and a thickness of not less than 10mm.

[0118] Furthermore, the flexible protective net 402 is woven from at least three steel hinged ropes, and the steel hinged ropes are made of at least four 3mm diameter steel wires. The inscribed circle diameter of the mesh of the flexible protective net 402 is 250mm (with an average positive error of no more than 5%), and the length-to-short diameter ratio of the mesh of the flexible protective net 402 is less than 2, thereby enabling it to withstand a tensile force greater than 30KN.

[0119] The velocity of a debris flow can be calculated using the following formula.

[0120]

[0121] Where μ is the debris flow velocity;

[0122] g—acceleration due to gravity;

[0123] h—Vertical height of debris flow;

[0124] a—Frame tilt;

[0125] This allows us to obtain the debris flow velocity under different frame inclination angles.

[0126] In this embodiment, when a debris flow arrives, the sensor assembly mounted on the flexible protective net assembly detects that the impact force of the debris flow exceeds a pre-set value. It then activates the drive assembly 501, which drives the third gear to rotate. This, in turn, causes the first gear and its shaft to rotate by a corresponding angle. This, in turn, causes the adjustment plate 506 mounted on the first gear shaft to rotate by a corresponding angle, thereby causing the flexible protective net mounted on the frame to rotate by the same angle. This allows the surface of the flexible protective net to rotate when impacted by the debris flow, effectively preventing stress concentration at a single location and preventing tearing of the flexible protective net.

[0127] In practical applications, to reduce the instantaneous impact force of debris flows and minimize the impact on flexible protective netting, please refer to... Figure 1-8 As shown, a buffer plate 603 is provided on one side of the flexible protective net 402, and the buffer plate 603 is provided in two sets. One set of the buffer plate 603 has at least one set of reinforcing plates 602 on its end face, and the reinforcing plates 602 are triangularly arranged. The reinforcing plates 602 are fixedly connected to the second anchor plate 604.

[0128] Furthermore, the second anchor plate 604 has a positioning hole, and a steel anchor rod is installed in the positioning hole, and the reinforcing plate 602 is connected through the steel anchor rod.

[0129] Furthermore, a first anchor plate 601 is provided on one side of the second anchor plate 604, and at least one set of buffer connectors 70 is provided between the first anchor plate 601 and the second anchor plate 604. The first anchor plate 601 is provided with a positioning hole, and a steel anchor rod is provided in the positioning hole, and the other set of buffer plates 603 is connected through the steel anchor rod.

[0130] Furthermore, both sets of buffer plates are provided with drainage ports.

[0131] In this embodiment, the triangular reinforcing plate 602 and the buffer plate are used in conjunction with the buffer connector to form a multi-level stress structure, which decomposes the impact force. The buffer connector 70 achieves secondary absorption of impact energy. Actual test data shows that the peak load can be reduced by 15%-45%. At the same time, the buffer plate can effectively intercept larger boulders, achieving the effect of interception and drainage.

[0132] Furthermore, the buffer connector 70 includes a housing 701 and a buffer base 708 that is tightly connected to the housing 701, and a buffer steel plate 707 is welded onto the buffer base 708, with the side end face of the buffer steel plate 707 being H-shaped.

[0133] Furthermore, buffer baffles 705 are fixedly installed on both sides of the buffer steel plate 707 by fastening screws. Two sets of buffer baffles 705 are arranged opposite each other. A buffer 706 is provided between the two sets of buffer baffles 705, and a buffer rod 702 is fixedly installed on the end face of the buffer baffle 705 away from the buffer steel plate 707.

[0134] Furthermore, connecting plates 703 are welded to both ends of the housing 701.

[0135] Furthermore, buffer structures are fixedly installed on the upper and lower end faces of the buffer steel plate 707. The buffer structures include an outer buffer member 7043, which is fitted onto the end face of the buffer steel plate 707. An inner buffer member 7042 is disposed within the outer buffer member 7043, and a buffer pad 7041 is disposed between the outer buffer member 7043 and the inner buffer member 7042. The buffer rod 702 is a primary buffer mechanism, and together with the outer buffer member, the inner buffer member, and the buffer pad disposed within the two sets of buffer members, it forms a secondary buffer mechanism.

[0136] Furthermore, the buffer rod 702 includes a buffer sleeve 7026, and a blocking end 7023 is provided inside the buffer sleeve 7026. The blocking end 7023 divides the cavity of the buffer sleeve 7026 into two sets of cavities, namely a first chamber and a second chamber. The chamber closer to the connecting seat is the first chamber, and the chamber farther away from the connecting seat is the second chamber. Both sets of cavities are filled with fluid, and the size of the two sets of cavities can be adjusted according to the blocking end 7023. The blocking end 7023 is provided with a channel.

[0137] Furthermore, the blocking end 7023 is disposed on the connecting rod 7022, and the connecting rod 7022 is provided with a connecting seat 7021 integrally disposed therewith, and a sealing gasket 7025 is disposed between the top end face of the buffer sleeve 7026 and the connecting seat 7021.

[0138] Furthermore, a connector 7027 is fixedly installed inside the buffer sleeve away from the connector 7021, and a support rod 7028 is connected through the connector 7027. The connector 7027 is provided with a mounting buckle, and the support rod 7028 is clamped to the outer wall through the mounting buckle. A control valve is installed on the end face of the support rod.

[0139] Those skilled in the art should understand that the elastic deformation time of the secondary buffer mechanism requires time. Therefore, if only the secondary buffer mechanism is used to reduce the impact of debris flow, the peak load will be directly transmitted to the flexible protective net, thereby causing damage to the flexible protective net. To address this, a primary buffer mechanism is added to one side of the secondary buffer mechanism. When debris flow occurs, the buffer rod of the primary buffer mechanism is subjected to force and pushes the connecting rod 7022 to move in the buffer sleeve 7026 through the connecting seat. At this time, the medium flows from the second chamber to the first chamber under the action of the control valve. During the process of the medium flowing through the channel, a force opposite to the direction of movement is generated, thereby achieving the purpose of primary buffering.

[0140] When the primary buffer mechanism is loaded, the external load gradually increases. When the load reaches the initial preload of the buffer 706, the buffer is compressed and generates a restoring force. As the deformation continues to increase, the buffer structure undergoes bending deformation and yielding energy dissipation, thereby achieving secondary buffering. This effectively reduces the impact force of debris flow and reduces damage to the flexible protective net.

[0141] The construction method for flexible protective barrier mechanisms used in debris flow geological disasters includes the following specific steps:

[0142] Step 1: Determine parameters such as pile foundation axis length, pile foundation width, and height based on the actual terrain conditions;

[0143] Step 2: According to the design protection standards of the prevention and control project, determine the installation positions of the two sets of buffer plates, install the buffer plates on the top end face of the pile foundation, then install the stainless steel plate, and pour concrete on the stainless steel plate to form a reinforcing plate.

[0144] By opening a positioning hole on the second anchor plate connected to the reinforcing plate, the steel anchor rod is placed in the positioning hole, and concrete is poured at the same time. Similarly, the other end of the steel anchor rod is installed on the first anchor plate.

[0145] Install another set of buffer plates in the same manner;

[0146] The distance between the front and rear sets of buffer plates is 'a', and L≤a≤3L, 50cm≤L≤350cm;

[0147] The buffer plate is laid at a height of H1 on the pile foundation, where H1 = H2 - H3 + h, H2 is the height of the pile foundation, H2 is the corresponding depth of the discharge outlet, and h is the reserved safety freeboard, and h does not exceed 0.65m.

[0148] Step 3: Determine the required thickness of the pile foundation and the required thickness of the rectangular groove through sampling tests, and open a rectangular groove 101 on the end face of the pile foundation 10;

[0149] Step 4: Install the adjustment mechanism. Install the drive component of the adjustment mechanism on the pile foundation, with the third gear and the second gear of the adjustment mechanism located in the rectangular groove, while the first gear 5031 of the adjustment mechanism extends out of the rectangular groove and is located in the mounting base.

[0150] A groove is formed on the end face of the mounting base 502 so that the adjustment plate 506 can pass through the groove, enter the interior of the mounting base 502, pass through the mounting base 502, and extend to the outside.

[0151] The frame 504 is mounted at an angle on the end face of the adjustment plate that extends outward through the mounting base 502;

[0152] Step 5: Install the flexible protective netting;

[0153] The reinforcing bars and the anchor rods of the first connecting ring 406 used to connect the steel wire ropes are installed on the reinforcing end 403. Then, concrete is poured to complete the installation of the first connecting ring anchor rods. The first connecting ring anchor rods need to be installed on the reinforcing ends of the four end faces of the frame, on the top, bottom, left and right.

[0154] Then, the wire rope is passed through the first connecting ring and wrapped around to form a connecting ring. The tail of the wire rope is then fixed to the wire rope with reinforcing fasteners to form a second connecting ring, thus completing the connection between the first and second connecting rings. Similarly, multiple sets of connecting rings are assembled in sequence to achieve the installation of multiple sets of wire ropes.

[0155] Step Six: Complete the connection between the flexible protective net and the steel wire rope, and fix the flexible protective net by the buckles set at the four corners of the anchoring connector 404;

[0156] The flexible protective net 402 is woven from at least 3 steel hinge ropes, and the steel hinge ropes are made of at least 4 steel wires with a diameter of 3mm.
