Description

Technical Field

[0001] This invention relates to the field of pile foundation protection technology, and in particular to a pile foundation reinforcement and protection device applied to road and bridge construction. Background Technology

[0002] As the core load-bearing component of the bridge superstructure, bridge pile foundations play a crucial role in transferring structural loads to the foundation. Their structural integrity directly determines the overall stability and operational safety of the bridge. Bridge pile foundation protection technology aims to resist damage from external environmental factors such as water erosion, debris impact, and chemical corrosion through targeted engineering measures, preventing structural damage or performance degradation of the pile foundations and ensuring the long-term safe service of the bridge.

[0003] Conventional bridge pile foundations often employ a rectangular cross-section design, with a planar frontal surface, lacking efficient diversion and buffering structures. Under conditions of rapid river flow, existing reinforcement structures generally suffer from insufficient impact stiffness and inadequate buffering performance, failing to effectively disperse the concentrated impact force of turbulent water flow. Over time, this can easily lead to the peeling of the surface concrete and corrosion of the internal steel reinforcement, resulting in pile tilting and displacement, seriously threatening the safety of the bridge structure. Furthermore, the flat sides and large surface area of ​​rectangular pile foundations easily create eddies around the pile foundation as water flows, causing floating garbage and suspended debris to accumulate. Existing protective structures lack targeted garbage interception and self-cleaning mechanisms. Under slow-flowing conditions, debris is difficult to dislodge naturally, and long-term attachment can breed microorganisms. The metabolic products of these microorganisms, combined with harmful substances in the garbage, accelerate the corrosion of the pile foundation concrete and the deterioration of the steel reinforcement, significantly shortening the service life of the pile foundation.

[0004] To address the aforementioned technical deficiencies, a solution is proposed: During slow flow, the guide plate expands to guide the water flow through the filter belt to intercept debris. The debris is then transferred by a lifting plate, cleaned by a scraper, and collected in a collection box by backwashing. During turbulent flow, the guide plate retracts to reduce the impact surface. Triangular guide columns divert the flow, and rotating edge columns assist in debris movement. The deflection of the triangular guide columns further prevents debris accumulation from obstructing the water flow. Through adaptive adjustment and self-cleaning, efficient debris treatment is achieved while ensuring smooth water flow and avoiding additional obstructions to the water flow. Summary of the Invention

[0005] The purpose of this invention is to provide a pile foundation reinforcement and protection device for road and bridge construction, in order to solve the aforementioned technical defects.

[0006] The objective of this invention can be achieved through the following technical solution: a pile foundation reinforcement and protection device applied to road and bridge construction, comprising a triangular seat fixedly installed on one side of the pile foundation, a triangular guide column installed on the triangular seat via a rotating rod, guide plates hinged to both sides of the triangular seat, and a reinforcement plate fixedly installed to the pile foundation, with an L-shaped mounting base fixedly installed on the guide plate, and rotating rollers rotatably installed on both the upper and lower sides of the L-shaped mounting base, the rotating rollers being connected by a filter belt drive, and multiple inclined lifting plates being fixedly installed at equal intervals on the filter belt.

[0007] Preferably, a collection box is installed on the top of the L-shaped mounting base on the side away from the triangular seat. A drive motor for driving the upper rotating roller is installed on the L-shaped mounting base by bolts. An inclined scraper is installed inside the L-shaped mounting base, and one side of the scraper slides against the inner wall of the filter belt on the side of the collection box. The L-shaped mounting base has a waste outlet that cooperates with the scraper.

[0008] Preferably, the reinforcing plates are fixedly connected to a fixing frame by bolts, and an I-shaped plate is slidably connected inside the fixing frame. A lead screw that is threadedly connected to the I-shaped plate is rotatably connected inside the fixing frame. A second drive motor that drives the lead screw to rotate is installed on the fixing frame by bolts. An ear plate is fixedly connected to the L-shaped mounting base, and a connecting plate is hinged between the ear plate and the I-shaped plate.

[0009] Preferably, when the I-beam and the fixed frame are in contact with the inner wall of the reinforcing plate, the distance between the hinge point on the I-beam and the L-shaped mounting seat is less than the distance between the hinge point on the ear plate and the L-shaped mounting seat.

[0010] Preferably, the top of the triangular base and the bottom of its inner wall are respectively provided with a limiting groove and a cylindrical groove, and a limiting slide is slidably installed in the limiting groove. A cylindrical block is rotatably connected in the cylindrical groove. The rotating rod is rotatably connected between the limiting slide and the cylindrical block. A pressure sensor is fixedly installed between the inner wall of the limiting groove near the reinforcing plate and the limiting slide. A servo motor that drives the rotating rod to deflect is installed on the limiting slide by bolts.

[0011] Preferably, each edge of the triangular guide column is rotatably connected to a rotating column, and multiple buffer components are provided inside the triangular guide column and between the rotating rod and each rotating column.

[0012] Preferably, the buffer includes a ball socket seat fixedly connected to the outer wall of the rotating rod and the inner wall of the triangular guide column, and a ball socket rod is rolledly embedded inside the ball socket seat. A circular plate is fixedly connected to the ball socket rod, and a buffer spring is fixedly connected between the circular plates.

[0013] Preferably, the buffer spring has a movable rod and a movable sleeve that are slidably connected to each other inside. The opposite ends of the movable rod and the movable sleeve are fixedly connected to the corresponding circular plate. Multiple damping holes are equidistantly opened on the outer wall of the movable sleeve along its length direction. A sealing ring that is slidably connected to the movable rod is embedded in the inner wall of the free end of the movable sleeve.

[0014] The beneficial effects of this invention are as follows: (1) This invention achieves protection and reinforcement of pile foundations under different water flow conditions through the diversion of the triangular guide column, multi-stage buffering and angle adjustment of the guide plate: the triangular guide column diverts the impact water flow and reduces the impact force of the water flow directly acting on the pile foundation; when turbulent or large-volume garbage impacts, the compression and stretching of multiple buffer springs achieves first-level anti-impact buffering, and the relative movement of the movable rod and movable sleeve, combined with the reduction of the number of damping holes, gradually strengthens the damping effect to form a second-level reinforced buffer, avoiding damage to the pile foundation caused by rigid impact; In addition, by monitoring the force on the triangular guide column caused by water flow impact in real time through pressure sensors, and by setting predetermined pressure data and overpressure time with an external controller, the guide plate is brought together during turbulent flow to reduce the water flow impact surface. At the same time, the intermittent deflection adjustment of the triangular guide column is used to prevent the accumulation of garbage and block the flow, thereby improving the structural stability of the pile foundation in complex water flow environment and achieving the effect of reinforcement and protection.

[0015] (2) In the slow flow state, the guide plate guides the diverted water flow through the filter belt. While the filter belt efficiently intercepts garbage and impurities in the water flow, the drive motor drives the filter belt and the lifting plate to move. The intercepted garbage is lifted and then falls into the collection box by gravity, thus not obstructing the flow of water. In addition, the scraper can cut and scrape the garbage that is inserted into the filter hole and cannot be separated. Combined with the rotation of the filter belt, the water flow achieves a backwashing and self-cleaning effect on the garbage in the filter hole, thereby effectively preventing the garbage from adhering to the surface of the pile foundation for a long time and causing corrosion damage, extending the service life of the pile foundation and reducing the later maintenance cost.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figures 1-7 and Figure 9 As shown, the existing bridge pile foundations mostly adopt a rectangular cross-section design, with a planar frontal surface and a lack of efficient diversion and buffer structures. The following solutions can be used to address this problem. The pile foundation reinforcement and protection device applied to road and bridge construction in this embodiment includes a triangular seat 1 fixedly installed on one side of the pile foundation body. A triangular guide column 2 is installed on the triangular seat 1 through a rotating rod 11. The triangular guide column 2 is used to divert the impact water flow and reduce the impact force of the water flow directly acting on the pile foundation body. Both sides of the triangular seat 1 are hinged with guide plates 12 and reinforcement plates 13 fixedly installed with the pile foundation body. The triangular seat 1 is fitted on the outside of the pile foundation. Through the large support surface at the bottom of the triangular seat 1, combined with the three sides covering the pile foundation, the reinforcement treatment of the road and bridge pile foundation is realized. The rotatably connected guide plate 12 is used for the diversion treatment of water flow during slow flow, and the water flow impact surface is reduced by the convergence of the guide plate 12 during turbulent flow, thereby realizing the regulation-type flow diversion protection treatment. An L-shaped mounting seat 14 is fixedly installed on the guide plate 12. Rotating rollers 15 are rotatably installed on both the upper and lower sides of the L-shaped mounting seat 14. The rotating rollers 15 are connected to each other through the transmission of the filter belt 16. Multiple inclined lifting plates 17 are fixedly installed at equal intervals on the filter belt 16.

[0020] A fixing frame 3 is fixedly connected between the reinforcing plates 13 by bolts, and an I-shaped plate 31 is slidably connected inside the fixing frame 3. A screw 32 that is threadedly connected to the I-shaped plate 31 is rotatably connected inside the fixing frame 3. A second drive motor that drives the screw 32 to rotate is installed on the fixing frame 3 by bolts. An ear plate 111 is fixedly connected to the L-shaped mounting base 14. A connecting plate 33 is hinged between the ear plate 111 and the I-shaped plate 31. When the water flow is slow, the second drive motor drives the lead screw 32 to rotate. The lead screw 32 pushes the I-shaped plate 31 to move closer to the pile body within the fixed frame 3. Combined with the connecting plate 33 between the I-shaped plate 31 and the ear plate 111, it pushes the two sets of guide plates 12 to move synchronously away from each other and expand. The expanded guide plates 12 further guide the diverted water flow. When the slow water flow becomes turbulent, the second drive motor drives the lead screw 32 to reverse, causing the two sets of guide plates 12 to deflect relative to each other, reducing the impact force of the turbulent water flow on the device.

[0021] When the I-shaped plate 31 and the fixed frame 3 are in contact with the inner wall of the reinforcing plate 13, the distance between the hinge point on the I-shaped plate 31 and the L-shaped mounting seat 14 is less than the distance between the hinge point on the ear plate 111 and the L-shaped mounting seat 14. The hinge point on the I-shaped plate 31 is closer to the pile body than the hinge point on the ear plate 111, forming a self-locking support for the two sets of guide plates 12 and providing stable support for the expanding guide plates 12. When the screw rod 32 is reversed, the I-shaped plate 31 moves to the other side of the fixed frame 3 to contact, providing stable support for the retracted guide plates 12, thereby avoiding reducing the service life of the screw rod 32.

[0022] The top of the triangular base 1 and the bottom of the inner wall are respectively provided with a limiting slide groove and a cylindrical groove. The limiting slide 112 is slidably installed in the limiting slide groove, and the cylindrical block 113 is rotatably connected in the cylindrical groove. The rotating rod 11 is rotatably connected between the limiting slide 112 and the cylindrical block 113. The limiting slide 112 and the cylindrical block 113 are provided for the rotating rod 11 to be installed, which has the purpose of vertical deflection, thereby realizing the detection of the degree of impact. A pressure sensor 114 is fixedly installed between the inner wall of the limiting slide groove near the reinforcing plate 13 and the limiting slide 112. A servo motor that drives the rotating rod 11 to deflect is installed on the limiting slide 112 by bolts. During the process of diverting the water flow on the impact side of the pile foundation through the triangular guide column 2, the impact of the water flow generates a thrust on the triangular guide column 2, causing it to tend to move closer to the pile foundation. This thrust is then transmitted to the limiting slide 112. The pressure sensor 114 detects the thrust of the limiting slide 112 in real time. The detection data is transmitted to an external controller. When the detection data is less than the preset data, it indicates a slow flow environment. The controller controls the drive motor 2 drive screw 32 to rotate forward, causing the two sets of guide plates 12 to expand in opposite directions for secondary guidance of the water flow. If the detected data is greater than the preset data, it indicates a turbulent environment or that garbage has accumulated on the triangular guide column 2. The controller controls the servo motor to drive the rotating rod 11 to deflect the triangular guide column 2, pushing the garbage accumulated on the triangular guide column 2 to one side. During this process, the controller presets the time for the triangular guide column 2 to deflect multiple times. After the preset time ends, if the detected data continues to be greater than the preset data, it indicates a turbulent environment. The controller controls the drive motor 2 to drive the lead screw 32 to reverse, causing the two sets of guide plates 12 to close relative to each other.

[0023] Each edge of the triangular guide column 2 is rotatably connected to a rotating column 21. Larger debris, driven by the water flow, contacts the corresponding diversion edge of the triangular guide column 2. If the debris is distributed to both sides of the triangular guide column 2, when one side is larger or other debris hits that side, the rotating effect of the rotating column 21 on the diversion edge helps the debris move at the diversion edge, thereby completing the self-cleaning of the unevenly distributed debris on both sides of the triangular guide column 2. Multiple buffers are provided inside the triangular guide column 2 and between the rotating rod 11 and each rotating column 21 to buffer the force when the triangular guide column 2 diverts the impact water flow.

[0024] The buffer includes a ball socket seat 22 fixedly connected to the outer wall of the rotating rod 11 and the inner wall of the triangular guide column 2, and a ball socket rod 23 is rolledly embedded inside the ball socket seat 22. The ball socket seat 22 and the ball socket rod 23 are used for universal movement between the rotating rod 11 and the triangular guide column 2. A circular plate 24 is fixedly connected to the ball socket rod 23, and buffer springs 25 are fixedly connected between the circular plates 24. When a large-mass and large-volume debris follows the turbulent water flow and impacts the triangular guide column 2, multiple buffer springs 25 in the diversion edge area at the impact point are compressed, and multiple buffer springs 25 in the other diversion edge areas are stretched, thereby achieving first-level impact-resistant buffer protection.

[0025] The buffer spring 25 has a movable rod 26 and a movable sleeve 27 that are slidably connected to each other. The opposite ends of the movable rod 26 and the movable sleeve 27 are fixedly connected to the corresponding circular plate 24. Multiple damping holes 28 are equidistantly opened on the outer wall of the movable sleeve 27 along its length. The movable rod 26 and the movable sleeve 27 move relative to each other in the diversion edge area at the impact point. The movable sleeve 27 below the liquid surface contains river water, while the movable sleeve 27 above the liquid surface contains air. By utilizing the relative movement between the movable rod 26 and the movable sleeve 27, the internal water or air is pushed out through multiple damping holes 28. During the relative movement, the number of damping holes 28 continuously decreases, gradually increasing the damping force of the relative movement between the two, thus strengthening the impact resistance and buffering, preventing large-volume debris from rigidly impacting the pile foundation along with the turbulent water flow, and reinforcing and protecting the pile foundation. The inner wall of the free end of the movable sleeve 27 is fitted with a sealing ring that slides and connects with the movable rod 26, increasing the sealing between the end of the movable sleeve 27 and the movable rod 26.

[0026] Example 2: Please refer to Figures 7-9 As shown, in response to the lack of targeted garbage interception, garbage tends to accumulate around the pile foundation during the slow flow process, making it difficult to separate naturally. Long-term attachment can breed microorganisms, whose metabolic products, together with harmful substances in the garbage, accelerate the corrosion of the pile foundation concrete and the deterioration of the steel bars, significantly shortening the service life of the pile foundation. The following solutions can be used to address this problem. The pile foundation reinforcement and protection device applied to road and bridge construction in this embodiment includes a triangular seat 1 fixedly installed on one side of the pile foundation. A triangular guide column 2 is installed on the triangular seat 1 via a rotating rod 11. Guide plates 12 are hinged to both sides of the triangular seat 1. A reinforcement plate 13 is fixedly installed on the pile foundation. An L-shaped mounting seat 14 is fixedly installed on the guide plate 12. Rotating rollers 15 are rotatably installed on both the upper and lower sides of the L-shaped mounting seat 14. The rotating rollers 15 are connected to each other through a filter belt 16. Multiple inclined lifting plates 17 are fixedly installed at equal intervals on the filter belt 16. When the water flow is slow, the two sets of guide plates 12 move in opposite directions until one side of the I-shaped plate 31 abuts against the inner wall of the fixed frame 3, forming a self-locking support for the two sets of guide plates 12. The guide plates 12 further guide the diverted water flow, causing the diverted water to contact the filter belt 16. The filter belt 16 intercepts the garbage in the water flow. The rotating roller 15 drives the filter belt 16 to move with multiple lifting plates 17. The lifting plates 17 drive the garbage and impurities filtered on the surface of the filter belt 16 to rise and then fall.

[0027] A collection box 18 is installed on the top of the L-shaped mounting base 14 on the side away from the triangular seat 1. During the descent of the garbage and impurities, the garbage falls into the collection box 18 automatically by gravity combined with the lifting plate 17 set below it. The collection box 18 has a discharge box cover for collecting and removing garbage. A drive motor for driving the upper rotating roller 15 to rotate is installed on the L-shaped mounting base 14 by bolts. An inclined scraper 19 is installed inside the L-shaped mounting base 14, and one side of the scraper 19 slides against the inner wall of the filter belt 16 located on the side of the collection box 18. The L-shaped mounting base 14 has a debris outlet 110 that cooperates with the scraper 19. Under the impact of water flow, the garbage is intercepted by the filter belt 16. Some small parts of the garbage penetrate the filter holes of the filter belt 16, preventing it from falling off during its downward movement. The scraper 19 attached to the inner wall of the filter belt 16 first cuts and scrapes off the penetrated garbage, allowing the remaining garbage to fall off smoothly. The cut garbage is guided to the discharge outlet 110 by the inclined setting of the scraper 19. Then, the flow of water impacts and backwashes the impurities in the filter holes of the filter belt 16 that have moved from top to bottom and are below the liquid surface, thus effectively preventing the garbage from adhering to the pile foundation surface for a long time and causing corrosion damage, extending the service life of the pile foundation and reducing the later maintenance costs.

[0028] Example 3: Please refer to Figures 1-9 As shown, the present invention also proposes a method for using a pile foundation reinforcement and protection device applied to road and bridge construction, comprising the following steps: Step 1: Place the triangular seat 1 on the outside of the pile foundation, and place the triangular guide column 2 on the triangular seat 1 on the water flow impact side of the pile foundation. Then fix the fixing frame 3 on the reinforcing plate 13 and complete the rotational installation between the connecting plate 33 and the I-shaped plate 31. Step 2: When the water flow is slow, the water flow is diverted to the impact side of the pile foundation by the triangular guide column 2. The impact of the water flow generates a thrust on the triangular guide column 2, causing it to tend to move closer to the pile foundation. The force is transmitted to the limiting slide 112 through the buffer. The thrust of the limiting slide 112 is detected in real time by the pressure sensor 114, and the detection data is transmitted to the external controller. When the detected data is less than the preset data, the controller controls the drive motor 2 to drive the lead screw 32 to rotate. The lead screw 32 pushes the I-shaped plate 31 to move closer to the pile body in the fixed frame 3. Combined with the connecting plate 33 between the I-shaped plate 31 and the ear plate 111, it pushes the two sets of guide plates 12 to move synchronously away from the expansion until one side of the I-shaped plate 31 touches the inner wall of the fixed frame 3. The hinge point on the I-shaped plate 31 is closer to the pile body than the hinge point on the ear plate 111, forming a self-locking support for the two sets of guide plates 12 and providing stable support for the expanding guide plates 12. The guide plates 12 further guide the diverted water flow, causing the diverted water to contact the filter belt 16, and the filter belt 16 intercepts the garbage in the water flow. Step 3: Drive motor 1 drives the corresponding rotating roller 15 to rotate. The rotating roller 15 drives the filter belt 16 to move with multiple lifting plates 17. The lifting plates 17 cause the garbage and impurities filtered on the surface of the filter belt 16 to rise and then fall. During the descent, the garbage and impurities fall into the collection box 18 automatically due to gravity combined with the lifting plates 17 below them. If, under the impact of water flow, a small part of the garbage penetrates the filter holes of the filter belt 16 and cannot fall down during the movement from top to bottom, the scraper 19 attached to the inner wall of the filter belt 16 first cuts and scrapes the part of the garbage that has penetrated, so that the garbage that has not penetrated can fall down smoothly. The cut garbage is guided to the discharge port 110 by the inclined setting of the scraper 19. Then, through the impact of the flowing water, the impurities in the filter holes of the filter belt 16 that have moved from top to bottom and below the liquid surface are backwashed and cleaned. Step 4: If a large piece of trash comes into contact with the corresponding diversion edge of the triangular guide column 2 under the influence of water flow, and the trash is distributed on both sides of the diversion surface of the triangular guide column 2, if one side is larger or other trash hits that side, the rotating column 21 on the diversion edge will help the trash move at the diversion edge, thereby completing the self-cleaning of the unevenly distributed trash on both sides of the triangular guide column 2. If the garbage cannot be cleaned by itself, as the garbage accumulates, the thrust on the triangular guide column 2 increases in the opposite direction. When the detected data is greater than the preset data, the controller controls the servo motor to drive the rotating rod 11 to deflect. The rotating rod 11, together with multiple buffers, synchronously drives the triangular guide column 2 to deflect, assisting in cleaning the garbage at the corresponding diversion edge of the triangular guide column 2, and preventing garbage from accumulating on one side of the pile foundation for a long time, which would cause long-term pollution and corrosion to the pile foundation. Step 5: When the slow-flowing water becomes turbulent, the thrust on the triangular guide column 2 is increased synchronously. The servo motor drives the triangular guide column 2 to deflect intermittently multiple times within a preset time. After the preset time ends, if the detection data is continuously greater than the preset data, the controller controls the drive motor 2 to drive the lead screw 32 to reverse, so that the I-shaped plate 31 moves to the other side of the fixed frame 3 to abut, causing the two sets of guide plates 12 to deflect relative to each other, so that the filter belt 16 is further tilted relative to the water flow impact direction, reducing the impact force of the turbulent water flow on the device. Step Six: When the turbulent water flow carries debris rapidly, if a large piece of debris impacts the triangular guide column 2, multiple buffer springs 25 in the diversion edge area at the impact point are compressed, while multiple buffer springs 25 in the remaining diversion edge areas are stretched, providing primary impact-resistant buffering protection. Simultaneously, the movable rod 26 and movable sleeve 27 in the diversion edge area at the impact point move relative to each other. The movable sleeve 27 below the liquid surface contains river water, while the movable sleeve 27 above the liquid surface contains air. With the relative movement of the movable rod 26 and movable sleeve 27, the water or air inside is pushed out through multiple damping holes 28. During the relative movement, the number of damping holes 28 continuously decreases, gradually increasing the damping force of the relative movement, thus further strengthening the impact-resistant buffering and preventing large-volume debris from rigidly impacting the pile foundation along with the turbulent water flow, thereby reinforcing and protecting the pile foundation.

[0029] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
