Description

Technical Field

[0001] This application relates to the field of riverbank, dam or waterway engineering maintenance, specifically to an ice-pressure resistant gabion footing submerged structure and its construction method. Background Technology

[0002] In water conservancy projects, slope protection, and ecological restoration, gabion submerged structures are widely used in riverbank protection and slope reinforcement projects due to their excellent structural stability, permeability, and environmental adaptability. Especially in cold regions, gabion submerged structures can overcome the challenges of short construction periods and poor construction conditions in winter through ice-based construction, effectively compensating for the shortcomings of traditional concrete structures, such as susceptibility to cracking and poor adaptability in freeze-thaw environments. Ice-based submerged structures, a commonly used winter construction technology in cold northern regions, can complete toe and slope protection construction during the ice-bound period, significantly improving construction efficiency and reducing the impact of seasonal factors on project progress. However, existing gabion-supported submerged structures still pose significant safety hazards during ice-based construction.

[0003] When constructing gabion-supported submerged structures on ice, it is necessary to fill the submerged structure with stones to achieve ballast fixation and meet the stability requirements of the engineering protection. However, the stone filling process generates concentrated and continuous vertical loads that directly act on the ice surface below. Due to the influence of factors such as uneven ice thickness, temperature fluctuations, and water flow impact, the bearing capacity of natural ice surfaces is significantly limited, and it is difficult to accurately predict weak areas. The instantaneous pressure generated by the filling stones can easily exceed the ice surface's bearing limit, leading to ice surface cracking and collapse. This can result in safety accidents such as construction workers falling and construction equipment falling into the water, which not only seriously threaten the personal safety of construction workers but also interrupt the construction process, increase construction costs, and even affect the construction quality and protective effect of subsequent projects.

[0004] Currently, there is no effective solution to the problem of ice surface breakage caused by the filling of gabion slabs with stones during ice surface construction. Existing gabion slab structures also lack dedicated support and protection mechanisms, which cannot alleviate the instantaneous pressure during stone filling and are difficult to meet the safety requirements of ice construction in cold regions, thus limiting the promotion and application of gabion slab structures in projects during the ice-bound period in northern regions.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0027] like Figures 1-2 As shown, this application proposes an ice-pressure-resistant gabion anchorage structure suitable for ice surface construction in riverbanks, dams, or waterway projects. The anchorage structure is placed on the ice surface where construction is being carried out. Specifically, the anchorage structure includes a gabion cage 1 and a support device. The support device is mounted on the gabion cage 1 to support it, reducing local pressure when the gabion cage 1 is filled with stones, preventing ice surface cracking and subsequent sinking of the gabion cage 1, which could affect construction progress or cause safety accidents. The support device has an extension component and a movable component; the extension component and the movable component are connected by a connecting mechanism to achieve linkage. Specifically, when the extension component is retracted, it can drive the movable component to extend from the bottom of the support device through the connecting mechanism, allowing the support device to move via the movable component, i.e., the support device can reciprocate on the gabion cage 1 through the movable component, flexibly adjusting its position. Furthermore, when the extension component is extended, it can drive the movable component to retract into the support device through the connecting mechanism; in the extended state, the extension component can increase the support area of ​​the gabion cage 1 on the ice surface, and the retracted movable component can avoid spatial interference during movement. Preferably, the extension components are in the naturally deployed state. The ice-pressure-resistant gabion footing submerged structure proposed in this application, by providing support devices on the gabion, can provide temporary support for the gabion and stones when filling them, resulting in a more even distribution of pressure, a larger stress area, and a reduced risk of ice surface breakage during construction; by designing the extension components to be linked with the moving parts, movement can be achieved while adjusting the support surface, facilitating construction.

[0028] like Figures 1-2 As shown, in some embodiments, the support device includes a base plate 2 and expansion plates 3, wherein the expansion plates 3 are symmetrically arranged at both ends of the base plate 2. Specifically, expansion components are respectively arranged on the expansion plates 3 at both ends of the base plate 2, and can be expanded or retracted on the expansion plates 3. A movable component is movably arranged on the base plate 2 and can extend out of the bottom of the base plate 2, thereby realizing the movement function. The cage 1 is movably arranged on the base plate 2 and located between the two expansion plates 3.

[0029] like Figures 2-3As shown, in some embodiments, mounting slots 4 and movable support seats 13 are respectively provided on the expansion plates 3 at both ends of the base plate 2, and the expansion assembly is disposed on the mounting slot 4. Specifically, the expansion assembly includes an expansion plate 27, which is telescopically disposed on the mounting slot 4; the expansion plate 27 and the movable support seat 13 are connected by a telescopic member; the movable support seat 13 is reciprocally disposed on the expansion plate 3, and the telescopic member drives the expansion plate 27 to expand or retract on the mounting slot 4.

[0030] like Figures 3-4 , Figure 7 As shown, in some embodiments, the extension assembly further includes an extension rod 25 and a slide rod 26, wherein both ends of the extension rod 25 are movably mounted on the mounting groove 4 via the slide rod 26. The slide rod 26 and the mounting groove 4 are slidably connected via a guide rail. The expansion plate 27 is provided with a second guide plate 24, and the expansion plate 27 is vertically and vertically mounted on the extension rod 25 via the second guide plate 24. Preferably, the telescopic component can be a multi-stage telescopic frame 22, one end of which is connected to the movable support base 13, and the other end of which is connected to the extension rod 25, so that the expansion plate 27 can be expanded or retracted on the mounting groove 4 by means of the extension rod 25.

[0031] like Figures 2-8As shown, in some embodiments, a fixed support base 11 is provided on the expansion plate 3; a movable support base 13 is reciprocally slidably disposed on the expansion plate 3 and connected to the fixed support base 11 via a tension spring 12. Specifically, one end of the tension spring 12 is fixedly connected to the fixed support base 11, and the other end of the tension spring 12 is fixedly connected to the movable support base 13. The tension spring 12 maintains tension on the movable support base 13 in its natural state, so that the movable support base 13 is in its rearmost position under normal conditions, that is, the multi-stage telescopic frame 22 remains in an extended state. A long slider 23 is provided on the second guide plate 24. The long slider 23 is slidably disposed on the second guide plate 24, and the movable support base 13 and the long slider 23 move in the same direction. One end of the multi-stage telescopic frame 22 is connected to the fixed support base 11 and the movable support base 13 respectively, and the other end of the multi-stage telescopic frame 22 is connected to one end of the long slider 23 and the extension rod 25 respectively. This connection allows the multi-stage telescopic frame 22 to move the long slider 23 and the extension rod 25 to the outside of the mounting groove 4 when it is unfolded. At the same time, it can also move the long slider 23 in the second sliding groove of the second guide plate 24, thereby moving the expansion plate 27 to the outside of the mounting groove 4 and upward. That is, when the long slider 23 and the extension rod 25 move to the outside of the mounting groove 4 and unfold, the expansion plate 27 can move outward synchronously with the extension rod 25. The expansion plate 27 can also move downward on the side of the extension rod 25. When the expansion plate 27 moves downward to the bottom, it can contact the ice surface, thereby playing an extended support role. Correspondingly, when the movable support 13 moves in the reverse direction, it can drive the multi-stage telescopic frame 22 to retract inward, that is, the multi-stage telescopic frame can drive the extension rod 25 to move inward and retract into the mounting groove 4. The multi-stage telescopic frame 22 can also drive the long slider 23 to slide backward. When the long slider 23 slides backward, it can also drive the extension plate 27 to move upward, thereby preventing motion interference when the extension plate 27 moves into the mounting groove 4. Similarly, when the movable support 13 moves forward, it allows the extension rod 25 and the extension plate 27 to move outward and unfold into the mounting groove 4. When it moves to the top of the mounting groove 4, the extension plate 27 can move downward and contact the ice surface.

[0032] like Figures 2-3 , Figure 6As shown, in some embodiments, the moving component can be a moving roller 20, and multiple moving rollers 20 are rotatably mounted on the base plate 2. The connecting mechanism includes a first guide plate 15 and an extension seat 19; wherein, the extension seat 19 is disposed on the first guide plate 15 and is movably mounted on the expansion plate 3 together with the first guide plate 15. The first guide plate 15 is connected to the moving roller 20 through the extension seat 19 to drive the moving roller 20 to move up and down on the base plate 2. Both ends of the moving roller 20 are rotatably mounted on the extension seats 19 on both sides of the expansion plate 3. The first guide plate 15 is provided with a first sliding groove, and the moving support seat 13 is provided with a first sliding pin 14. The moving support seat 13 is slidably disposed in the first sliding groove through the first sliding pin 14 to drive the first guide plate 15 to move up and down on the expansion plate 3, that is, the moving support seat 13 drives the first guide plate 15 to move up and down by driving the first sliding pin 14 to slide in the first sliding groove. Specifically, to achieve the lifting function of the movable roller 20 on the base 2, the first sliding groove sequentially includes a lower horizontal groove section 16, a long inclined groove section 17, and an upper horizontal groove section 18. When the first sliding pin 14 is located in the lower horizontal groove section 16, the first guide plate 15 is at its highest position. At this time, the first guide plate 15 drives the movable roller 20 to retract into the base plate 2 via the extension seat 19. When the first sliding pin 14 slides through the long inclined groove section 17 into the upper horizontal groove section 18, the first guide plate 15 is at its lowest position. At this time, the first guide plate 15 drives the movable roller 20 to extend out of the bottom of the base plate 2 via the extension seat 19. When the movable roller 20 extends out of the bottom of the base plate 2, it can lift the entire support device, thereby facilitating the control of the support device to move to a designated position. When the movable roller 20 retracts into the base 2, the support device is in normal support mode.

[0033] like Figure 6 As shown, when the first sliding pin 14 is on the inner wall of the lower transverse groove section 16, it can support and limit the first guide plate 15, the extension seat 19, and the moving roller 20. At this time, the moving roller 20 is in a stable state at the top position. When the first sliding pin 14 is on the inner wall of the upper transverse groove section 17, it can lock the first guide plate 15 and the moving roller 20. At this time, the moving roller 20 is in a stable state at the bottom position. Figure 1 and 2 As shown, when the movable support 13 drives the first sliding pin 14 to move in the opposite direction, the first sliding pin 14 can slide from the inner wall of the lower horizontal groove section 16 into the long inclined groove section 17. At this time, the first guide plate 15 and the movable roller 20 can move downward. When the movable support 13 drives the first sliding pin 14 and others to continue moving forward to the top, the first sliding pin 14 can enter the upper horizontal groove section 18. At this time, the first guide plate 15 and the movable roller 20 can move downward to the lowest position, that is, to contact the ice surface and lift up the entire support device. This makes it easier to drive the support device to move to the next position to be supported.

[0034] like Figures 2-3 , Figure 8As shown, in some embodiments, the second guide plate 24 is provided with a second sliding groove; the long slider 23 is slidably disposed in the second sliding groove through the second sliding pin 28 to drive the second guide plate 24 to rise and fall. The second sliding groove includes a short horizontal groove section 29, a short inclined groove section 30, and a long horizontal groove 31; when the multi-stage telescopic frame 22 is fully extended and the second sliding pin 28 is located in the short horizontal groove section 29, the second guide plate 24 is at its lowest position, and the expansion plate 27 is fully extended and lowered to its lowest position; when the multi-stage telescopic frame 22 is retracted and the second sliding pin 28 slides through the short inclined groove section 30 into the long horizontal groove 31, the second guide plate 24 is at its highest position, and the expansion plate 27 retracts into the mounting groove 4. Specifically, when the long slider 23 drives the second sliding pin 28 from the short transverse groove section 29 into the short inclined groove section 30, the second guide plate 24 and the expansion plate 27 can move upward, meaning the expansion plate 27 disengages from the ice surface. When the long slider 23 drives the second sliding pin 28 into the long transverse groove section 31, the second guide plate 24 and the expansion plate 27 can move upward to the top position, facilitating entry into the mounting groove 4 for retraction. When the second sliding pin 28 engages with the short transverse groove section 29, it can lock the position of the expansion plate 27, meaning the extension assembly is in the extended state, and the expansion plate 27 is in a stable state at the bottom, providing stable support for the extension assembly.

[0035] like Figures 2-5As shown, in some embodiments, the support device also includes a cage correction assembly, which is respectively disposed at both ends of the base plate 2 to clamp and correct the cage 1, preventing the cage 1 from collapsing and spreading to both sides when filled with stones, and ensuring that the cage 1 has a symmetrical shape. The cage 1 is located between the cage correction assemblies at both ends of the base plate 2; specifically, the cage correction assembly includes a correction plate 6 and an arc-shaped guide plate 7, with the arc-shaped guide plate 7 symmetrically disposed at both ends of the correction plate 6. The base plate 2 is provided with a threaded seat 9, and the correction plate 6 is connected to the threaded seat 9 through a threaded rod 8, so that it can move telescopically on the threaded seat 9. Specifically, one end of the threaded rod 8 is rotatably connected to the inner wall of the correction plate 6, and the correction plate 6 can reciprocate on the upper surface of the base plate 2 to make adaptive adjustments according to the width of the cage 1. The outer surface of the threaded rod 8 is connected to the threaded seat 9 through threads, and a handle 10 is provided on the other end face of the threaded rod 8, which facilitates the rotation of the threaded rod 8. When the threaded rod 8 rotates, it can drive the correction plate 6 to move to the designated position. The threaded connection between the threaded rod 8 and the threaded seat 9 has a self-locking function, that is, when the threaded rod 8 does not rotate, the position of the correction plate 6 is fixed, making the structure more reliable. By adopting the above scheme, by providing a cage correction component on the support device, the support device can correct both sides of the cage 1 when moving, making the cage 1 more symmetrical and easier to fill with stones. Among them, the correction plate 6 can clamp and correct the cage 1, preventing the cage 1 from collapsing and spreading to both sides when filling with stones. The arc-shaped guide plate 7 can make the two sides of the correction plate 6 flare out, which facilitates the movement of the correction plate 6 on both sides of the cage 1.

[0036] like Figure 7 As shown, the movable support base 13 is equipped with a pull ring 21, which facilitates driving the movable support base 13 to move forward (i.e., move in the opposite direction). That is, by pulling the pull ring 21 with a drive mechanism or manually, the movable support base 13 can be moved forward, and the tension spring 12 can be stretched. When the movable support base 13 moves forward to the top, the multi-stage telescopic frame 22 can be driven to drive the extension component to retract, and the movable roller 20 can be extended to the bottom of the base plate 2 to lift the support device. Continue to pull the pull ring 21 to move, so that the support device reaches the designated position. After moving to the designated position and releasing, the movable support base 13 and the pull ring 21 move forward and reset under the tension of the tension spring 12. The extension component can be extended again, and the movable roller 20 can be moved upward and retracted into the base plate 2. The support device is in the use support state, and stones can be filled into the net cage 1 on the support device.

[0037] like Figures 2-3As shown, in some embodiments, the side of the base plate 2 is provided with a shovel 5, which can lift the bottom of the gabion 1, so that the support device can be flexibly adjusted at the lower end of the gabion 1. That is, the shovel 5 can lift the bottom of the gabion 1 during the movement of the support device, so that the support device can be moved at the lower end of the gabion 1, that is, the position of the support device can be adjusted according to the position of the construction operation.

[0038] This application also proposes a construction method for an ice-pressure-resistant gabion footing submerged embankment, employing the aforementioned submerged embankment structure; specifically, the construction method includes the following steps: S1: The sinking structure is placed on the ice surface during construction, and the expansion plate 27 of the extension component is in the unfolded state in its natural state and in contact with the ice surface; S2: Fill the gabion 1 of the sinking structure with stones, and the correction plate 6 of the gabion correction component on the support device corrects the gabion 1 along the side of the gabion 1 so that the side of the gabion 1 remains flat. S3: When the support device needs to be moved, the moving support base 13 is moved in the opposite direction on the expansion plate 3 by the drive mechanism or by manual pulling. During the reverse movement, the moving support base 13 drives the expansion plate 27 to retract inward on the expansion plate 3 through the telescopic component. When the expansion plate 27 retracts inward on the expansion plate 3, the expansion plate 27 rises and retracts into the mounting groove 4 of the expansion plate 3. During the reverse movement, the moving support base 13 also drives the moving component to extend out of the bottom of the support device through the connecting mechanism. S4: The moving part drives the support device to move on the cage 1 by rotating, while the arc-shaped guide plate 7 of the cage correction component guides along the side of the cage 1, and the shovel 5 on the bottom plate 2 lifts the bottom of the cage 1.

[0039] The ice-pressure resistant gabion footing submerged structure and construction method proposed in this application have the following technical advantages: (1) The sinking structure proposed in this application can quickly deploy and form a stable contact with the ice surface when the net cage is filled with stones, so as to evenly distribute the vertical pressure generated by the filling stones to a larger area of ​​the ice surface, effectively reduce the pressure on the local ice surface, avoid the ice surface from breaking and collapsing due to local pressure overload, fundamentally solve the problem of the ice surface easily breaking when the traditional sinking structure is filled with stones, eliminate the safety hazards such as construction personnel falling and equipment falling into the river, ensure the safety of personnel and equipment throughout the ice construction process, reduce the difficulty of construction safety management, greatly improve the safety of ice construction, and effectively avoid safety accidents; (2) The sinking structure proposed in this application can provide support in real time without frequent stops for testing, which can ensure the continuous progress of the stone filling operation; at the same time, the support device can be moved flexibly to adapt to the filling needs of different areas of the sinking and to the operational characteristics of ice surface construction, which greatly improves the efficiency of ice construction and shortens the limited construction cycle in cold regions. (3) The gabion submerged structure proposed in this application has a movable support device, which does not affect the flexibility and permeability of the submerged structure itself. It retains the original advantages of gabion submerged structures in adapting to uneven settlement of the foundation and alleviating frost heave pressure. Furthermore, by supplementing the support function, it further improves the stability of the submerged structure during the ice surface construction stage, avoids the displacement and damage of the submerged structure due to ice surface breakage, ensures that the submerged structure can be accurately positioned after filling with stones, guarantees the engineering quality of subsequent toe protection and slope protection, adapts to the construction needs of ice surfaces of different thicknesses and complex ice conditions, and broadens the application range of gabion submerged structures in cold regions. It is especially suitable for ice construction projects such as riverbank protection and land protection. (4) The submerged raft structure proposed in this application has a compact support device structure design that can be adapted to the existing gabion submerged raft structure without the need for large-scale modification of the main structure of the submerged raft. It is easy to produce, process and install on site without the need for additional complex construction procedures and equipment, thus reducing costs. At the same time, the support device can be reused and can be recycled for subsequent ice construction, further reducing project investment. It is both practical and economical, and easy to promote and apply in the engineering field. It can effectively promote the optimization and upgrading of ice surface submerged raft technology and solve the core problem of winter bank protection construction in cold regions.
