Abstract
Description
Technical Field
[0001] This utility model relates to the field of flood control technology, specifically to a deformable guardrail and a guardrail installation structure that helps improve the flood control capacity of river embankments. Background Technology
[0002] Guardrails are usually installed on both sides of the banks of rivers, lakes, reservoirs, and riverside roads to beautify the environment, delineate areas, and prevent pedestrians and vehicles from accidentally falling into the water.
[0003] In some special river and reservoir environments, during severe flood seasons, floodwaters often overflow guardrails and riverbanks, causing flooding disasters in urban areas, villages, and farmland. To address this issue, flood control and emergency response departments typically issue advance warnings and promptly lay flood-control sandbags on the riverbanks before the floodwaters submerge the guardrails, thus mitigating the impact and losses caused by flooding. However, when laying flood-control sandbags on both sides of the riverbank, the sandbags rely entirely on their own weight to stack on the riverbank, resulting in poor impact resistance. Improving impact resistance would require increasing the number of sandbags, which in turn leads to drawbacks such as large sandbag usage and long laying time.
[0004] In response to the above situation, the applicant intends to utilize the existing protective railings along the riverbank as a support structure for flood control sandbags, thereby improving the sandbags' impact resistance. However, traditional railings primarily focus on strength and aesthetics in their structural design, resulting in a relatively limited function. Furthermore, railings are typically installed on the side of the riverbank closer to the water, making it difficult to provide adequate support for the sandbags. Therefore, it is essential to redesign the railings on both sides of the riverbank to ensure proper securing of the sandbags during the flood season. Utility Model Content
[0005] In view of this, one of the objectives of this utility model is to provide a deformable guardrail that can restrain sandbags after deformation, improve the ability to resist flood impact, and help reduce the amount of sandbags to be laid.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows:
[0007] A deformable guardrail includes two parallel posts, characterized in that: each post has an open sliding channel at its upper end; each of the two posts has a sliding guide rod installed in the sliding channel; the upper ends of both guide rods extend beyond the top of the posts; an upper crossbar connects the upper ends of the two guide rods; a middle crossbar connects the two posts; and an avoidance notch is provided on the inner side of the upper end of each of the two posts; the deformable guardrail has a guardrail state and a flood control state; in the guardrail state, the guide rods are held in place within the sliding channel by their own weight; when the guide rods slide upward to their highest position, they can flip towards the side where the avoidance notch is located, thus switching the deformable guardrail to the flood control state.
[0008] With the above structure, when a flood occurs, sandbags are stacked longitudinally at the guardrail, and then the guardrail is folded over. The weight of the guide rods and the upper crossbars is used to press down on the sandbags, which can increase the sandbags' ability to withstand water erosion and thus increase flood resistance.
[0009] Preferably, the column has slotted holes on both sides adjacent to the clearance notch, extending along the height of the column. A pin is located at the bottom of the guide rod, with both ends of the pin slidably passing through the slotted holes. The upper end of the slotted hole is higher than the lower end of the clearance notch. This structure, through the slotted holes and pin, limits the sliding direction and stroke of the guide rod, ensuring more stable lifting. The fact that the upper end of the slotted hole is higher than the lower end of the clearance notch ensures that when the guide rod slides to the uppermost point of the slotted hole, it can fold and deform towards the side where the clearance notch is located.
[0010] Preferably, the upper end of the guide rod is provided with a connecting sleeve, the bottom cross-sectional dimension of the connecting sleeve is greater than or equal to the horizontal cross-sectional dimension of the top of the column, and the connecting sleeve is provided with a mounting hole, through which the end of the upper crossbar passes. With the above structure, the connecting sleeve facilitates the installation of the upper crossbar and also enhances the overall aesthetics of the guardrail.
[0011] Preferably, the connecting sleeve is an inwardly curved arc-shaped structure. With this structure, when the guardrail folds and deforms, the arc-shaped connecting sleeve can better fit the sandbag, thus applying force to the sandbag and ensuring its flood-resistant effect. Furthermore, setting the connecting sleeve to an arc shape further enhances the overall aesthetics of the guardrail.
[0012] Preferably, both ends of the central crossbar are equipped with connecting plates, which are bolted to the side of the column. This structure ensures stable installation of the central crossbar without affecting the normal sliding of the guide rod.
[0013] The second objective of this utility model is to provide a guardrail installation structure that helps improve the flood control capacity of river embankments, including a river embankment, wherein the deformable guardrails are arrayed at the edge of the river embankment, and the deformable guardrails are connected to each other by a through connecting rod, which passes through the lower part of all the posts.
[0014] By adopting the above structure, the force applied to the sandbags by the deformation of each guardrail can increase the structural strength of the stacked sandbags, ensuring the flood resistance effect of the sandbags. The connecting rods can increase the structural strength between each guardrail.
[0015] Preferably, each deformable guardrail on the riverbank surface is equipped with a fixed base for mounting ropes. With this structure, when the guardrail deforms and flips, the upper crossbar can be connected and fixed to the fixed base via ropes, preventing the guide bar from swaying, further increasing the constraint on the sandbags, and improving the resistance to flood impact.
[0016] Preferably, the base of each of the aforementioned posts is embedded into the riverbank through a casting process. This structure further ensures the structural strength of the guardrail and prevents it from being washed away by floods.
[0017] Preferably, a storage trough is provided on the side of the top of the river embankment away from the deformable guardrail. Sandbags are pre-stored in the storage trough, and a cover is provided on the storage trough. With the above structure, the storage trough can conveniently store sandbags under normal circumstances, and when flood control is needed, the sandbags can be quickly stacked at the guardrail.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] 1. The deformable guardrail provided by this utility model, after being installed on the outer edge of the river embankment, can be used as a guardrail in normal conditions to prevent pedestrians and vehicles from falling into the water. When a flood warning is issued during the flood season, flood control sandbags can be laid on the river embankment inside the guardrail, ensuring that the sandbags are against the inside of the guardrail. Then, the two guide rods and the upper crossbar are lifted upwards to the highest position of the uprights, and then the two guide rods are flipped inwards so that the guide rods and the upper crossbar press down on the flood control sandbags, thereby improving the sandbags' resistance to flood impact.
[0020] 2. The sandbags are pressed against the inside of the guardrail by the guide rods and the upper crossbars. Compared with the traditional method of directly laying flood control sandbags, the number of sandbags required is significantly reduced, which has significant advantages in terms of economy and laying efficiency.

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.
[0030] Example 1:
[0031] like Figures 1 to 3 As shown, a deformable guardrail includes two parallel posts 1. The posts 1 have a sliding channel 1b with an open upper end. Each of the two posts 1 has a guide rod 2 that can slide up and down installed in the sliding channel 1b. The upper ends of the two guide rods 2 extend beyond the top of the posts 1. An upper crossbar 3 is connected between the upper ends of the two guide rods 2. A middle crossbar 6 is connected between the two posts 1. A clearance notch 1a is provided on the inner side of the upper end of each of the two posts 1.
[0032] like Figure 1 , Figure 4 and Figure 5 As shown, the deformable guardrail has a guardrail state and a flood control state. In the guardrail state, the guide rod 2 is held in the sliding channel 1b by its own weight. When a flood occurs, sandbags 10 are first stacked on the inside of the deformable guardrail, and then the upper horizontal bar 3 is pulled upward so that the guide rod 2 slides relative to the column 1 to the highest position. Finally, the guide rod 2 and the upper horizontal bar 3 are flipped toward the side where the clearance gap 1a is located so that the deformable guardrail switches to the flood control state.
[0033] Based on this structure, the sandbag 10 is pressurized by the weight of the guide rod 2 and the upper crossbar 3, thereby improving the sandbag 10's resistance to flood impact and also helping to reduce the amount of sandbag 10 laid.
[0034] To ensure sufficient pressure exerted on the sandbag 10 by the guide rod 2 and the upper crossbar 3, both are solid metal components in this embodiment. In addition, a fixing seat 9 can be installed on the surface of the riverbank 7. When the deformable guardrail folds and deforms to press onto the sandbag 10, the upper crossbar 3 is fixed to the fixing seat 9 by ropes 11. At this time, the upper crossbar 3 and the guide rod 2 together have superior flood resistance. In the implementation plan, if ropes 11 are used to fix the upper crossbar 3, due to its good impact resistance, the guide rod 2 and the upper crossbar 3 can be made into hollow structures to reduce the operating force required to lift and fold the guide rod 2, thereby improving the efficiency of flood control and disaster relief.
[0035] like Figure 3As shown, a strip hole 1c is provided on each of the two surfaces adjacent to the clearance notch 1a of the column 1. The strip hole 1c extends along the height direction of the column 1. A pin 4 is fixedly provided at the bottom of the guide rod 2. Both ends of the pin 4 slide through the strip hole 1c, and the upper end of the strip hole 1c is higher than the lower end of the clearance notch 1a. Through the design of the pin 4 and the strip hole 1c, the sliding direction and sliding distance of the guide rod 2 can be restricted, thereby ensuring that the guide rod 2 is more stable when sliding up and down. The fact that the upper end of the strip hole 1c is higher than the lower end of the clearance notch 1a ensures that when the guide rod 2 slides to the uppermost end of the strip hole 1c, it can bend and deform towards the side where the clearance notch 1a is located, avoiding motion interference.
[0036] like Figure 1 and Figure 2 As shown, a connecting sleeve 5 is fixedly installed at the upper end of the guide rod 2. The bottom cross-sectional dimension of the connecting sleeve 5 is greater than or equal to the horizontal cross-sectional dimension of the top of the column 1. An installation hole 5a is provided on the connecting sleeve 5, and the end of the upper crossbar 3 passes through the installation hole 5a. Based on this structure, the connecting sleeve 5 facilitates the installation of the upper crossbar 3. When the deformable guardrail is in the guardrail state, the connecting sleeve 5 can support the top of the column 1, so that the guide rod 2 is hidden inside the column 1, ensuring the overall aesthetics of the structure.
[0037] In this embodiment, the connecting sleeve 5 is an inwardly curved arc structure. Based on this structure, when the guardrail is flipped and deformed, the arc-shaped connecting sleeve 5 can better contact the sandbag 10, thereby applying pressure to the sandbag 10 and improving the overall flood control effect. In addition, setting the connecting sleeve 5 as an arc structure further enhances the overall aesthetics of the guardrail.
[0038] For example Figure 2 As shown, connecting pieces 6a are provided at both ends of the middle crossbar 6. The connecting pieces 6a are locked to the side of the column 1 by bolts 6b. In this embodiment, two middle crossbars 6 are arranged in parallel between the two columns 1. The design of the middle crossbar 6 increases the overall structural strength of the guardrail. In addition, the middle crossbar 6 also increases the overall protection of the guardrail, preventing people from accidentally falling into the water. The installation and fixing by bolts 6b can avoid affecting the normal sliding of the guide rod 2.
[0039] Example 2:
[0040] like Figure 6 and Figure 7 As shown, this embodiment 2 provides a guardrail installation structure that helps improve the flood control capacity of river embankments. Specifically, it includes a river embankment 7, and deformable guardrails as described in embodiment 1 are arrayed and installed at the edge of the river embankment 7. Each deformable guardrail is connected to the other by a through connecting rod 8. In this embodiment, a connecting hole 1d is provided at the bottom of each column 1, and the connecting rod 8 passes through each connecting hole 1d.
[0041] Furthermore, fixed seats 9 are installed at the locations of each deformable guardrail on the river embankment 7. When the deformable guardrail is folded and deformed, the fixed seats 9 and the upper crossbar 3 can be fixed by ropes 11 to prevent the guide rod 2 and the upper crossbar 3 from swaying. In addition, the ropes 11 can further pressurize the sandbag 10 to ensure the overall flood resistance strength. Based on the design of the fixed seats 9, the guide rod 2 and the upper crossbar 3 can be set as hollow structures to reduce the overall weight of the guide rod 2 and the upper crossbar 3, thereby enabling the deformable guardrail to deform quickly.
[0042] Specifically, such as Figure 8 As shown, the fixing seat 9 includes a groove 9a set on the surface of the riverbank 7 and a fixing rod 9b placed horizontally on the top of the groove 9a. The rope 11 is fixedly wrapped around the fixing rod 9b and the upper crossbar 3.
[0043] To further enhance the structural strength of the deformable guardrail, in this embodiment, the bottom of each post 1 is embedded inside the river embankment 7 by casting.
[0044] For example Figure 6 As shown, a collection trough 7a is provided on the top of the river embankment 7 away from the deformable guardrail. Sandbags 10 are pre-stored in the collection trough 7a. A cover plate 7b is provided on the collection trough 7a. When no flood disaster occurs, the collection trough 7a can facilitate the collection of sandbags 10. When a flood disaster occurs, the sandbags 10 can be quickly stacked inside the deformable guardrail. The cover plate 7b can ensure the aesthetics of the river embankment 7 and prevent people from accidentally falling into the collection trough 7a.
[0045] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
