Description

Technical Field

[0001] The utility model relates to the technical field of rope net application, in particular to a flexible blocking protection system for a flooded bridge. Background Art

[0002] A flood bridge is a simple ordinary bridge built on a river. When the water level rises slightly, the bridge can flow over the bridge deck. On a secondary road, it crosses a river with a large difference between the normal water level and the flood level and is not navigable. At the same time, if the flood time is short and the traffic is allowed to be temporarily interrupted, the bridge elevation can be designed according to the normal water level, and the water flow is allowed to flow over the bridge deck during the flood. The flood bridge is a choice made by the traditional stone slab bridge to adapt to the traffic of mountain streams. The flood bridge is usually low. Once a flood occurs, the water can flow over the bridge deck. The bridge body is hidden in the water flow to resolve part of the impact of the flood and avoid the danger of trees and weeds caused by mountain torrents. The cost is much cheaper than other "tall" bridges, and it can be destroyed and rebuilt from time to time. In order to allow floods to pass smoothly, some flood bridges are specially designed to be concave with a low middle and high sides to avoid causing damage to the bridge itself.

[0003] At present, there are still a large number of flooded bridges in many areas. When the river flows during the flood season every year, or when the gates of the upstream lakes and reservoirs release water, the flow of the river increases, the water level overflows the bridge deck, and the passage of pedestrians and vehicles cannot be effectively controlled. Accidents often occur, and even cause tragedies of car crashes and deaths, posing a great threat to the safety of life and property of residents. In order to prevent accidents, columns are usually set at a certain distance on both sides of the flooded bridge, but the gaps between the columns still pose a risk of vehicles and pedestrians falling into the river. For this reason, metal chains are connected between the columns on some flooded bridges. However, due to the heavy weight of the metal chains and the long-term exposure to the air and water, they are prone to corrosion. After a period of time, the metal chains will fall or even drag on the ground, and they cannot play the due protective role. In addition, long-term corrosion causes the connection to be unstable. Once a collision accident occurs, the metal chains cannot play a solid blocking role, and there is a risk of people and vehicles falling into the water. In addition, the connection construction and installation of the metal chain and the column are inconvenient, and improper operation can easily damage the column, reducing the protection quality and effect of the column itself. Summary of the invention

[0004] In order to solve the above-mentioned technical problems, the utility model provides a blocking and protective device for a flooded bridge, which is simple to install and easy to replace. The synthetic fiber rope has high strength and light weight. It not only has a reminder function but also can effectively reduce safety hazards such as falling into water caused by the impact of pedestrians or vehicles in accidental situations.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is:

[0006] A blocking and protective device for a flooded bridge comprises a stake guardrail, a turnbuckle and a flexible chemical fiber rope, wherein rigid annular components are fixedly provided on both sides of the top of the stake guardrail, a plurality of the stake guardrails are spaced apart on both sides of the flooded bridge, a flexible chemical fiber rope is connected between every two stake guardrails, eyelets at both ends of the flexible chemical fiber rope are respectively tightened and connected to the rigid annular component on the top of the stake guardrail by turnbuckles, the flexible chemical fiber rope is adjusted and tightened by the turnbuckles when it creeps and sags, and luminous and reflective reminder marks are provided on the flexible chemical fiber rope.

[0007] The flexible chemical fiber rope is woven from colored fibers, and a coating of luminous material is added to the rope to form a rope with a luminous reminder mark.

[0008] The flexible chemical fiber rope is configured to add reflective strips into chemical fiber materials for blending to form a rope with a reflective reminder mark.

[0009] The flexible chemical fiber rope is configured to be a rope with a luminous reminder mark by adding luminous fiber material into the chemical fiber material for blending.

[0010] The eyelet of the flexible chemical fiber rope is connected with a metal ring.

[0011] On the basis of the original stakes, the utility model replaces the metal chain with a flexible chemical fiber rope, which not only ensures the strength of the blocking component but also reduces the weight of the blocking component. The flexible chemical fiber rope is tightened and connected to the stakes on both sides through basket screws. Even if the rope creeps and sags, the tightening state can be adjusted to ensure that the blocking component plays a corresponding blocking and protective role. The flexible chemical fiber rope used is provided with a luminous or reflective reminder mark, which emits light to remind in the dark and improves safety performance. The basket screw connection is simple to operate, and the rope is easy to repair and replace. The rope is light in weight, which reduces the pulling damage to the pillars on both sides and extends the service life of the overall device. The cost is low and the protective effect is good, and it is suitable for large-scale promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the structure of the utility model. DETAILED DESCRIPTION

[0013] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments:

[0014] like Figure 1As shown, the flexible blocking protection device for a flooded bridge comprises a pile guardrail 1, a basket screw 2 and a flexible chemical fiber rope 3. Rigid annular components 11 are fixedly arranged on both sides of the top of the pile guardrail 1. A plurality of the pile guardrails 1 are arranged at intervals on both sides of the flooded bridge. A flexible chemical fiber rope 3 is connected between every two pile guardrails 1. Eyelets 31 at both ends of the flexible chemical fiber rope 3 are respectively tightened and connected with the rigid annular component 11 on the top of the pile guardrail 1 through the basket screw 2. When the flexible chemical fiber rope 3 creeps and sags, it is adjusted and tightened through the basket screw 2. Luminous and reflective reminder marks are arranged on the flexible chemical fiber rope 3.

[0015] As a preferred manner, in an embodiment of the present utility model, the flexible chemical fiber rope 3 is woven from colored fibers, and a coating of luminous material is added to the rope to form a rope with a luminous reminder mark 32 .

[0016] As a preferred method, in another embodiment, the flexible chemical fiber rope 3 can also be configured to add reflective strips into the chemical fiber material for blending into a rope with a reflective reminder mark 32. In this embodiment, the reflective strips and the chemical fiber are blended and woven regularly to form a rope, which increases the reflective function. When light shines on the rope in the dark, the reflective material will reflect the light, which serves to remind passing vehicles or pedestrians, thereby improving safety.

[0017] As a preferred method, in another embodiment, the flexible chemical fiber rope 3 can also be configured to add luminous fiber material into the chemical fiber material for blending into a rope with a luminous reminder mark 32. After the rope absorbs visible light, the light energy is stored in the rope, which glows in a dark environment to remind passing vehicles or pedestrians to pay attention to safety.

[0018] As a preferred embodiment, a metal ring is connected to the eyelet 31 of the flexible chemical fiber rope 3 to increase the wear resistance of the rope.

[0019] In the specific implementation process of the utility model, firstly, a flexible chemical fiber rope 3 with a reminder mark is made, and the chemical fiber material can be selected from ultra-high molecular weight polyethylene, polyester, polyamide, etc., and the making of the reminder mark can be set according to any of the above embodiments; then, the flexible chemical fiber rope 3 is cut according to the designed spacing between the two stake guardrails 1, and eyelets 31 are woven at both ends, and metal rings are connected at the eyelets 31 to increase the wear resistance of the rope; the two ends of the basket screw 2 are respectively connected to the eyelet 31 of the flexible chemical fiber rope 3 and the rigid annular component 11 of the column guardrail 1, and the spacing is adjusted so that the flexible chemical fiber rope 3 is in In the tensioned state, when the rope sags due to creep after a period of time, the rope can be tightened again by rotating the basket screw 2 and adjusting the spacing. In this way, the flexible chemical fiber rope 3 can be kept in a tensioned state for a long time, effectively realizing its reminder and protection functions. The installation is simple, and the maintenance and replacement are convenient. If a single flexible chemical fiber rope 3 has a problem, just replace it. In addition, the flexible chemical fiber rope 3 is light in weight and has high lightness. In the tensioned state, the pulling force on the stake guardrails 1 on both sides is relatively small, avoiding damage to the stake guardrails 1 on both sides due to the pulling of the rope during use, thereby extending the service life of the overall protective device.

[0020] Since flooded bridges are mostly built in mountainous areas or places with inconvenient transportation, the requirements for protection should be given more attention. At the same time, the maintenance and repair costs should be relatively low to meet the application prospects. The utility model not only achieves the reminder and protection functions, but also reduces the construction cost and later maintenance cost. It is easy to install and has good protection effect. It meets the application requirements of flooded bridge protection in large areas and ensures the personal and property safety of passing vehicles and personnel at low cost.

[0021] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
