A rotating shaft is coaxially fixed to both ends of the outer cylinder, and the two ends of the rotating shaft are rotatably connected to the corresponding horizontal plates. The invention also includes cushioning modules, with each roller mechanism having a corresponding cushioning module. This invention, by setting up the roller mechanisms and corresponding cushioning modules, can cushion vehicles when they collide with the fence, thereby reducing the damage to vehicles and people caused by the fence.

[0005] While existing fixed fences have good strength and buffering effect, temporary fences are mostly used for protection during temporary construction on highways. However, temporary fences are mostly made of metal or plastic, which have low strength, limited function, and are not easy to achieve good protection and warning effects. Summary of the Invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing temporary fences used for highway construction have low strength, limited function, and are not easy to achieve a good protective effect.

[0007] To address the aforementioned problems, this invention provides a crash barrier for highway construction, comprising a main barrier with a warning strip connected to its top and a reflective warning plate installed on the warning strip. The main fence is connected to a pair of fixed seats at the bottom, and auxiliary posts are installed on the fixed seats. The auxiliary posts include a base that is snapped into the fixed seats, a top plate on the upper side of the base, and a pair of posts connected between the base and the top plate.

The support platforms are provided with wire holes that match the girdle. Multiple webbing straps are fixed to the cable tie seat by buckles, and buffer bladders are connected between the multiple webbing straps. The outer end of the buffer bladder is fixedly connected to a buckle that matches the webbing strap.

[0008] Among the aforementioned crash barriers used in highway construction, those that facilitate rapid erection of a strong buffering effect during temporary construction are preferred.

A flexible air pipe matching the air valve is installed on the exhaust pipe.

[0012] As another improvement of this application, the shroud passes through both ends of the support platform, and a brake bolster matching the shroud is installed on the support platform. The brake bolster includes an adjusting bolt that is threaded to the support platform, and an elastic brake block is connected to one end of the adjusting bolt located in the wire hole.

[0013] As a further improvement to this application, a monitoring device and a positioning module are installed on the main fence. The monitoring device is equipped with a distance measuring module and a speed measuring module. LED lights are installed on the warning strip.

[0019] The numbers in the diagram are as follows: 1 Main fence, 2 Auxiliary post, 21 Brake bolt, 201 Base, 202 Top plate, 203 Post, 204 Support platform, 3 Warning strip, 4 Enclosure tape, 5 Cable tie, 6 Clip, 7 Buffer bag. Detailed Implementation

[0020] The three embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0021] Implementation method 1: Figure 1-7 As shown, a crash barrier for highway construction includes a main fence 1, a warning strip 3 connected to the top of the main fence 1, and a reflective warning plate installed on the warning strip 3; The lower end of the main fence 1 is connected to a pair of fixed seats, and auxiliary posts 2 are installed on the fixed seats; the fixed seats are provided with two pairs of round holes and multiple pairs of slot holes. Figure 6 The arrangement of slots and round holes includes: slots and round holes are arranged alternately, with the slots located between two pairs of round holes; To improve stability, counterweights are added to the mounting base, for example, by embedding it into a concrete structural component before use. The auxiliary column 2 includes a base 201 that is snapped into the fixed seat. The center of gravity of the auxiliary column 2 is located at the base 201. The base 201 is inserted into the fixed seat. A top plate 202 is provided on the upper side of the base 201. A pair of columns 203 are connected between the base 201 and the top plate 202. Multiple evenly distributed support platforms 204 are fixedly connected to the columns 203. A shroud 4 and a cable tie 5 are respectively connected to the support platforms 204 of the pair of columns 203. Both ends of the shroud 4 are connected to a buckle 6 that matches the cable tie 5. A wire hole matching the shroud 4 is opened on the support platform 204. Multiple straps 4 are fixed to the cable tie base 5 by buckles 6. A buffer bladder 7 is connected between the multiple straps 4. The outer end of the buffer bladder 7 is fixedly connected to a buckle that matches the strap 4. The buffer bladder 7 and the strap 4 are fixed by multiple buckles.

[0022] The shroud 4 passes through both ends of the support platform 204, and the support platform 204 is equipped with a brake bolt 21 that matches the shroud 4; the brake bolt 21 includes an adjusting bolt that is threaded to the support platform 204, and an elastic brake block is connected to one end of the adjusting bolt located in the wire hole; when the tension on the shroud 4 is greater than the frictional force of the elastic brake block on it, the shroud 4 can be pulled out from the support platform 204. The portion of the shroud 4 located between a pair of support platforms 204 is connected to a base surface strip, on which a buffer layer is laid, and perforations matching the shroud 4 are opened.

[0023] Optionally, straps can be used to further secure the auxiliary post 2 to the main fence 1 to further improve the stability of the auxiliary post 2; The main fence 1 of this scheme can be set as a pair, and the buffer 7 can be sandwiched in the middle by the pair of main fences 1, which makes it easy to protect the buffer 7 and prevents the buffer 7 from being damaged by accidents in the construction site. This solution involves installing auxiliary columns 2 in the slots of the fixed base to set up multi-layer buffer bags 7, so that multi-layer buffer measures can be quickly built on the rear side of the main fence 1 to improve the anti-collision effect of the fence. When setting up the buffer bladder 7 in this scheme, the fence is installed, and multiple main fences 1 are fixed by multiple fixing seats. Then, auxiliary columns 2 are installed on the fixing seats and fixed to the fixing seats. At this time, the two ends of the sash 4 passing through the support platform 204 are fastened to the cable tie seat 5 by the buckle 6. Then, the sash 4 is pulled to straighten the sash 4 between a pair of support platforms 204. Finally, the brake bolster 21 is adjusted to pressurize and fix the sash 4. Then, the unfilled buffer bladder 7 is set on the sash 4 and fixed to the sash 4 by the buckle on the outside of the buffer bladder 7. Then, the buffer bladder 7 is filled with filling material, including sand, water and gas. The filling port of the buffer bladder 7 is located at the top and the filling port is threaded with a sealing plug. In this embodiment, when there is sufficient material at the construction site to fill the buffer bladder 7, only the unfilled buffer bladder 7 needs to be transported during transportation, which occupies less transportation resources. After the main fence 1 of this embodiment is impacted, it is buffered by the buffer bladder 7. During the impact process, the tension of the fence 4 is greater than the friction force applied to it by the brake bolster 21. At this time, the fence 4 is pulled in the direction of the impact force. When the fence 4 is stretched, the buffer layer on the base of the fence 4 interacts with the support platform 204 to buffer the fence 4, making it less likely for the fence 4 to interact with the support platform 204 and break. It also plays a certain buffering role. Multi-level buffering is achieved through the main fence, multiple buffer bladders 7, enclosure belts 4, and buffer layers on the base belt to reduce external impact forces.

[0024] Furthermore, this implementation method is easy to install, requiring only installation on the back of an existing fence, and can also be used as a standalone flexible fence; it is versatile and flexible in its application scenarios, suitable for various usage environments.

[0025] This implementation facilitates the rapid erection of guardrails with strong anti-collision capabilities during temporary road construction, ensuring the safety of the construction site and personnel.

[0026] The second implementation method: Figure 8-10 As shown, the buffer bladder 7 includes an outer bladder body, an inner bladder bag installed inside the outer bladder body, a filling port located on the inner bladder bag, solid filler of the buffer bladder 7 being filled into the inner bladder bag, a sealing cap being installed at the top of the inner bladder bag, multiple inflation valves and deflation valves being installed on the outer bladder body, and a counterweight seat being provided at the bottom of the buffer bladder 7. After the buffer bladder 7 is set up, the counterweight seat rests on the ground.

[0027] Multiple inflation valves are distributed at different heights and positions on the support platform 204. Air pipes can be connected to one inflation valve, so that long air pipes do not need to be installed on the support platform 204. An exhaust pipe is installed on the support platform 204, an air guide channel is opened in the column 203, a T-shaped pipe is connected between the column 203 and the exhaust pipe, an air supply pipe is connected to the base 201, an air pump is connected to the base 201 through the air supply pipe, the input end of the air guide channel is connected to the air supply pipe, the air supply pipe is connected to the column 203, and a flexible air pipe matching the air filling valve is installed on the exhaust pipe.

[0028] The main fence 1 is equipped with monitoring equipment and positioning modules. The monitoring equipment is equipped with a ranging module and a speed measuring module. The warning strip 3 is equipped with LED lights. The main fence 1 is equipped with photovoltaic panels that are electrically connected to the monitoring equipment and LED lights.

[0029] It also includes a collision warning system, which includes a control terminal. The control terminal is connected to a communication module, a data processing module, a power distribution module, an alarm module, and an equipment control module. The air pump and monitoring equipment are both connected to the equipment control module. The monitoring equipment on multiple adjacent main fences 1 is connected to one control terminal, and the photovoltaic panels on multiple main fences 1 are all connected to the power distribution module. The alarm module is connected to an audible and visual alarm device and a communication alarm device. The communication module is connected to the Internet. The communication module can upload the location information of multiple main fences 1 to the navigation system, so that the location of the construction area can be quickly displayed in the navigation system; In this embodiment, the buffer bladder 7 ensures the buffering effect only through the filling material inside the inner bladder bag under normal use. When the monitoring equipment detects a vehicle approaching within a set distance at a speed exceeding the set speed, the air pump inflates the outer bladder to further enhance the buffering capacity of the buffer bladder 7. The output end of the air pump in this embodiment is connected to a diversion device, so that one air pump can inflate multiple buffer bladders 7 at the main fence 1 at the same time. Compared to the first embodiment, in this embodiment, the buffer bladder 7 is not inflated under normal conditions to avoid the buffer bladder 7 from rupturing due to high temperature environment, and is only inflated for protection under certain conditions. This embodiment facilitates monitoring and alarms via a monitor installed on the fence. Compared to the first embodiment, the buffer bladder 7 in this solution does not need to be fully filled. When there is not enough material available to fill the buffer bladder 7 at the construction site, only the inner bladder of the buffer bladder 7 is pre-filled with suitable filler before transportation, and the outer bladder is only inflated under set conditions to compensate for the cushioning capacity; this embodiment is suitable for situations where there is not enough material at the construction site to fill the buffer bladder 7; it is easy to ensure that the buffer bladder 7 has sufficient cushioning effect and does not occupy too much transportation resources. In summary, this solution facilitates the rapid erection of a fence with strong buffering effect during temporary construction. The buffer bladder 7 can further enhance the buffering effect in emergencies, and the fence also provides an alarm, making it easy to ensure the safety of the construction site. Considering current practical needs, the above-described embodiments adopted in this application are not limited to these specific implementations. Various modifications made within the scope of knowledge possessed by those skilled in the art, without departing from the concept of this application, still fall within the protection scope of this invention.
