Description

Technical Field

[0001] This invention belongs to the field of ancient embankment protection technology, specifically referring to an in-situ protection and reinforcement device for the ancient embankment heritage of the Grand Canal. Background Technology

[0002] As an important linear cultural heritage site, the ancient embankments of the Grand Canal have long been subjected to erosion by water flow, wave impact, soil softening, and freeze-thaw cycles, making them prone to slope spalling, local collapses, and overall landslides, seriously threatening the safety of the heritage site and the continuation of its water conservancy functions. Current in-situ protection and reinforcement of the ancient embankments mostly employs traditional techniques such as rigid retaining walls, riprap revetments, and concrete linings, which have many drawbacks: rigid structures have poor coordination with the deformation of the ancient embankment soil, are prone to cracking due to uneven foundation settlement, and construction disturbances are significant, easily damaging the original structure of the heritage; traditional wave-breaking components only passively resist impacts and cannot dissipate wave energy in stages, making them prone to overturning and failure under strong waves; anchoring and support systems are mostly fixed structures, unable to dynamically adjust anchoring depth and anti-sliding capacity according to wave force, resulting in insufficient overall stability; the devices are mostly integral structures, inconvenient to disassemble and maintain, the materials have weak corrosion and aging resistance, are prone to rust and degradation after long-term service, resulting in high maintenance costs and short lifespans.

[0003] Furthermore, existing technologies cannot simultaneously achieve the principle of minimal intervention in heritage protection, the safety of water conservancy protection, and the convenience of operation and maintenance, thus failing to meet the engineering requirements for long-term in-situ protection of the Grand Canal's ancient embankment heritage. Summary of the Invention

[0004] In view of the above situation and to overcome the shortcomings of the existing technology, the present invention provides an in-situ protection and reinforcement device for the ancient embankment heritage of the Grand Canal, which effectively solves the problems currently on the market.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes an in-situ protection and reinforcement device for the ancient embankment heritage of the Grand Canal, comprising: a plate installation assembly, an impact dispersion assembly, and an impact conversion structure;

[0006] The plate mounting assembly includes a baffle body, insert pins, fixing tubes, detachable plates, and locking bolts. The insert pins are evenly and fixedly connected to the bottom surface of the baffle body. The fixing tubes are obliquely and fixedly connected to the back side of the baffle body. The detachable plates are embedded in the preset grooves of the baffle body. The locking bolts are evenly arranged at the connection between the baffle body and the detachable plates.

[0007] The impact dispersion component includes an arc-shaped mesh plate, a sliding block, a connecting rod, a damper, and a buffer spring. The arc-shaped mesh plate is evenly arranged on the wave-facing surface of the baffle body. The sliding block is slidably connected to the baffle body. The arc-shaped mesh plate is rotatably connected to the sliding block through the connecting rod. The damper and the buffer spring are both connected between the sliding block and the baffle body.

[0008] The impact conversion structure includes a fixed sleeve, a moving rod, a return spring, a bearing tube, a connecting tube, a telescopic airbag, a transmission tube, a rotating plate, a torsion spring, a liquid storage tank, a diversion tube, a telescoping device, and a reinforcing rod. The fixed sleeve is fixedly installed on the baffle body. The moving rod is slidably connected to the fixed sleeve, and an arc-shaped mesh plate is fixedly connected to the end of the moving rod. The return spring is disposed inside the fixed sleeve. The bearing tube is embedded inside the baffle body. The fixed sleeve is connected to the bearing tube through the connecting tube. The telescopic airbag is installed inside the bearing tube, which is connected to the transmission tube. The rotating plate and the torsion spring are installed inside the transmission tube. The transmission tube is connected to the liquid storage tank. The liquid storage tank is connected to the telescoping device through the diversion tube. The telescoping device is installed inside the fixed tube, and a telescoping reinforcing rod is connected to the end of the telescoping device.

[0009] Furthermore, the bottom of the plug is set as a conical structure, the plug and the baffle body are integrally formed or welded together, and the edge of the baffle body is chamfered.

[0010] Furthermore, the fixing tube is inclined at an angle of 30°-60° to the baffle body, the fixing tube is made of seamless steel pipe, the surface of the detachable plate matches the groove size of the baffle body, and the locking bolt passes through the detachable plate and is threadedly locked to the baffle body.

[0011] Furthermore, the arc-shaped mesh plate has an overall arc-shaped protrusion structure, and the arc-shaped mesh plate body is evenly provided with water-permeable holes, which are set as any one of circular, square or rhomboid shapes.

[0012] Furthermore, the two ends of the connecting rod are respectively rotatably hinged to the arc-shaped mesh plate and the sliding block, the damper and the buffer spring are arranged in parallel to each other, and the buffer spring is sleeved on the outside of the damper.

[0013] Furthermore, a sealed cavity is formed between the fixed sleeve and the moving rod, and the sealed cavity is filled with hydraulic oil. The two ends of the return spring are respectively fixedly connected to the inner wall of the fixed sleeve and the end of the moving rod.

[0014] Furthermore, the inner diameter of the telescopic airbag matches the outer diameter of the connecting tube, the edge of the rotating plate is set with an arc-shaped structure, and the rotating plate can rotate and open inside the transmission tube.

[0015] Furthermore, one end of the torsion spring is fixedly connected to the rotating plate, and the other end of the torsion spring is fixedly connected to the inner wall of the transmission pipe. The torsion spring is used to drive the rotating plate to reset and close.

[0016] Furthermore, the liquid storage tank is embedded and fixed inside the baffle body, and the liquid storage tank is pre-filled with hydraulic oil. The liquid storage tank is connected to the internal cavity of the telescopic device through a diversion pipe.

[0017] Furthermore, the reinforcing rod is slidably connected inside the fixed tube, and the tail of the reinforcing rod is fixedly connected to the output end of the expansion joint. The expansion joint is driven to extend and retract by hydraulic oil, which drives the reinforcing rod to extend and insert into the bottom soil to achieve reinforcement.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows:

[0019] (1) The main body of the baffle is made of high-strength anti-corrosion composite material. The bottom conical plug-in nail guides the embedding into the bottom soil. The initial positioning is accurate and the anchoring force is large. It can quickly achieve vertical fixation and effectively block the collapse of the soil and the scouring of the water flow. The device is laid in place without large-area excavation, which minimizes the disturbance to the ancient embankment heritage and the surrounding environment. It conforms to the principle of minimal intervention protection of cultural heritage. The arc-shaped mesh plate on the wave-facing side is diverted by the arc-shaped curved surface and the water-permeable holes, which initially disperses the continuous surging waves and reduces the impact intensity. It is combined with the connecting rod, sliding block, damper and buffer spring to form a mechanical buffer circuit, which converts the impact kinetic energy into elastic potential energy and damping dissipation energy. It effectively buffers small waves and unloads large waves, which greatly improves the device's wave resistance and overturning resistance.

[0020] (2) The impact conversion structure realizes the graded response of wave force through hydraulic transmission: when the waves are small, the hydraulic oil causes the telescopic airbag to expand and store energy and quickly reset; when the waves are large, the hydraulic oil drives the telescopic device to extend and push the reinforcing rod to insert obliquely into the bottom soil, automatically increasing the lateral support force and anchoring depth, forming an integrated mechanism of passive protection and active reinforcement, and maintaining structural stability under extreme water flow conditions.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0036] like Figures 1-11 As shown.

[0037] In some embodiments, the plate mounting assembly 1 may include a baffle body 101 for preventing embankment collapse; insert pins 102, evenly distributed on the bottom surface of the baffle body 101, and fixedly connected to the baffle body 101 for insertion into the bottom of the water to keep the baffle body 101 vertical; a fixing tube 103, inclined and fixedly connected to the baffle body 101; a detachable plate 104, disposed on the baffle body 101; and locking bolts 105, evenly distributed at the connection between the baffle body 101 and the detachable plate 104, the locking bolts 105 penetrating and slidingly connecting the detachable plate 104, and the locking bolts 105 threadedly connecting the baffle body 101.

[0038] The bottom of the plug-in nail 102 is conical, and the baffle body 101 is made of high-strength anti-corrosion composite material. It is vertically arranged, with a flat surface and chamfered edges. It is used to directly block the embankment soil and prevent water erosion from causing embankment collapse and landslides, providing a structural support foundation for the entire device.

[0039] The insert pins 102 are evenly distributed on the bottom surface of the baffle body 101 and are integrally formed or welded to the baffle body 101. The bottom is conical with the tip of the cone facing down. The conical structure has guiding embedding properties and can be quickly inserted into the underwater soil to increase the contact area and interlocking force with the soil, thereby achieving the initial positioning and vertical fixation of the baffle body 101 and preventing the baffle body 101 from tilting or displacing due to wave impact.

[0040] The fixing tube 103 is inclinedly fixed to the back of the baffle body 101 (away from the side of the surging waves), forming an angle of 30°-60° with the baffle body 101. It is made of seamless steel pipe and provides an installation cavity and guide support for the lateral dynamic reinforcement structure.

[0041] The detachable plate 104 is embedded in the pre-set groove of the baffle body 101, and the plate surface size matches the groove to achieve modular splicing.

[0042] In some embodiments, the impact dispersion component 2 may include an arc-shaped mesh plate 201, evenly distributed on the outer surface of the baffle body 101, for dispersing surging waves; a sliding block 202, slidably connected to the baffle body 101; a connecting rod 203, rotatably connected at one end to the arc-shaped mesh plate 201 and at the other end to the sliding block 202, for transmitting the kinetic energy of the arc-shaped mesh plate 201; a damper 204, fixedly connected at one end to the sliding block 202 and at the other end to the baffle body 101, for buffering the displacement of the sliding block 202; and a buffer spring 205, sleeved on the damper 204, fixedly connected at one end to the sliding block 202 and at the other end to the baffle body 101.

[0043] The arc-shaped mesh plate 201 is evenly distributed on the wave-facing surface of the baffle body 101. The plate surface has an arc-shaped raised structure, and the plate body has evenly arranged permeable holes. The hole shape is round, square or rhomboid. The arc-shaped structure can change the direction of the surging wave. The permeable holes divide the large area of ​​continuous surging wave into multiple small water streams, realize the initial dispersion of surging wave energy, and reduce the direct impact intensity.

[0044] When the surge impacts the arc-shaped mesh plate 201, the surge is dispersed by the perforated structure on the arc-shaped mesh plate 201, and the arc-shaped mesh plate 201 will be displaced under the impact of the surge. The arc-shaped mesh plate 201 drives the sliding block 202 to slide on the baffle body 101 through the connecting rod 203. The sliding block 202 squeezes the damper 204 and the buffer spring 205 to be displaced. The damper 204 buffers the impact force transmitted by the arc-shaped mesh plate 201. After the surge recedes, the arc-shaped mesh plate 201 returns to its initial position under the action of the buffer spring 205.

[0045] In some embodiments, the impact conversion structure 3 may include a fixed sleeve 301, fixedly installed on the baffle body 101; a movable rod 302, slidably connected inside the fixed sleeve 301, with one end of the movable rod 302 away from the fixed sleeve 301 fixedly connected to the arc-shaped mesh plate 201; a return spring 303, disposed inside the fixed sleeve 301, with one end of the return spring 303 fixedly connected to the fixed sleeve 301 and the other end of the return spring 303 fixedly connected to the movable rod 302; a bearing tube 304, evenly distributed inside the baffle body 101, with the bearing tube 304 embedded in and connected to the baffle body 101; and a connecting tube 305, one end of which passes through and is fixedly connected to the fixed sleeve 301, and the other end of which passes through and is fixedly connected to the bearing tube 304. The system includes: a hydraulic oil transfer chamber; a telescopic airbag 306, housed within a bearing pipe 304; a transfer pipe 307, one end of which passes through and is fixedly connected to the bearing pipe 304; a rotating plate 308, rotatably connected within the transfer pipe 307, used to block the flow of hydraulic oil; a torsion spring 309, located at the connection between the rotating plate 308 and the transfer pipe 307, one end of which is fixedly connected to the rotating plate 308, and the other end of which is fixedly connected to the transfer pipe 307; a reservoir 310, embedded in and fixedly connected to the baffle body 101; a diverter pipe 311, housed within the baffle body 101; a telescopic device 312, fixedly installed within a fixed pipe 103; and a reinforcing rod 313, slidably connected within the fixed pipe 103, with the reinforcing rod 313 fixedly connected to the telescopic device 312.

[0046] The inner diameter of the telescopic airbag 306 is equal to the outer diameter of the connecting pipe 305. The edge of the rotating plate 308 is arc-shaped, allowing the rotating plate 308 to rotate within the transmission pipe 307. The diversion pipe 311 is connected to the liquid storage tank 310 and the telescopic device 312. Hydraulic oil is provided in the cavity between the moving rod 302 and the fixed sleeve 301, and hydraulic oil is also provided in the telescopic device 312.

[0047] When the arc-shaped mesh plate 201 is impacted by a surge, the moving rod 302 compresses the return spring 303 inside the fixed sleeve 301, simultaneously forcing the hydraulic oil inside the fixed sleeve 301 into the bearing tube 304. If the impact force of the surge is small, the hydraulic oil entering the bearing tube 304 cannot cause the rotating plate 308 to rotate, thus causing the telescopic airbag 306 inside the bearing tube 304 to expand under pressure. After the surge disappears, the moving rod 302, under the action of the return spring 303, drives the arc-shaped mesh plate 201 to return to its original position. At the same time, the hydraulic oil inside the telescopic airbag 306 will expand under pressure. Under the pressure of 06, it re-enters the fixed sleeve 301; if the impact force of the surge is large, the hydraulic oil entering the bearing pipe 304 will squeeze the rotating plate 308 after filling the telescopic airbag 306 and enter the storage tank 310 through the transmission pipe 307. The storage tank 310 is initially filled with hydraulic oil. After being injected with external hydraulic oil, it will squeeze the hydraulic oil in the original storage tank 310 into the diversion pipe 311, and the hydraulic oil in the diversion pipe 311 will enter the expansion joint 312, causing the expansion joint 312 to extend and push the reinforcing rod 313, so that the reinforcing rod 313 is inserted into the seabed.

[0048] In practical use, the baffle body 101 is vertically arranged, and the conical plugs 102 evenly distributed on the bottom surface are inserted into the soil at the bottom of the water. The guiding and anchoring force of the conical structure ensures that the baffle body 101 is stable and upright, preventing the embankment soil from collapsing. The inclined fixed pipe 103 provides an installation foundation for the lateral support. The detachable plate 104 is locked and fixed to the baffle body 101 by locking bolts 105, realizing modular assembly and convenient maintenance, and ensuring the stability and detachability of the overall structure of the device.

[0049] When the surge impacts the baffle body 101, the arc-shaped mesh plate 201, evenly distributed on the outer surface, first absorbs the impact. Its perforated structure can directly divide and disperse the large-area surge, achieving initial dispersion of the surge energy. At the same time, the arc-shaped mesh plate 201 is displaced under the thrust of the surge, and the kinetic energy is transferred to the sliding block 202 through the connecting rod 203, driving the sliding block 202 to slide along the baffle body 101. During the sliding process, the sliding block 202 compresses the damper 204 and the buffer spring 205. The damper 204 consumes the impact energy and buffers the instantaneous impact force through the damping effect, and the buffer spring 205 compresses and stores energy simultaneously. After the surge recedes, the buffer spring 205 releases its elastic potential energy, pushing the sliding block 202 to reset, and then the arc-shaped mesh plate 201 is driven back to its initial position through the connecting rod 203, completing one buffer reset cycle.

[0050] When the impact force of the surge is small, the arc-shaped mesh plate 201 drives the moving rod 302 to slide along the fixed sleeve 301, compressing the return spring 303 and squeezing the hydraulic oil in the fixed sleeve 301 into the bearing pipe 304. Due to insufficient hydraulic oil pressure, the rotating plate 308 cannot be pushed open, and the hydraulic oil only causes the telescopic airbag 306 in the bearing pipe 304 to expand and store energy. After the surge disappears, the return spring 303 pushes the moving rod 302 to reset, and the telescopic airbag 306 contracts to return the hydraulic oil to the fixed sleeve 301, thus completing the small wave buffering.

[0051] When the impact force of the surge is large, the hydraulic oil pressure first fully inflates the telescopic airbag 306, and then continuously increases the pressure to open the rotating plate 308 (the torsion spring 309 stores the force). The hydraulic oil enters the storage tank 310 through the transmission pipe 307. The original hydraulic oil in the storage tank 310 is squeezed and transported to the telescopic device 312 in the fixed pipe 103 through the diversion pipe 311. The telescopic device 312 extends under the action of the hydraulic oil, pushing the reinforcing rod 313 to slide outward along the fixed pipe 103 and insert into the seabed soil, which greatly improves the anchoring force and anti-overturning ability of the device, realizing dynamic reinforcement against the impact of strong waves. After the surge subsides, the torsion spring 309 drives the rotating plate 308 to reset and close. The reset spring 303 and the telescopic airbag 306 work together to return the hydraulic oil, the telescopic device 312 retracts, the reinforcing rod 313 resets, and the device returns to its initial standby state. The above is the overall working process of the present invention. This step can be repeated for the next use. The actual operation process is very simple and easy.
