Description
Technical Field
[0001] This utility model relates to the field of road construction facilities technology, specifically a guardrail for road construction projects. Background Technology
[0002] Roads are where all kinds of cars travel. As cars travel on the road, the road surface will be damaged, such as cracks and potholes. In order to ensure the normal driving of vehicles, the road needs to be repaired. During the repair work, it is necessary to set up guardrails around the construction site. This not only warns vehicles on the road, but also prevents debris such as gravel and sand from falling on the intact road surface and affecting the driving of cars.
[0003] A road construction guardrail, disclosed in patent CN213391492U, includes two bases positioned on the left and right sides. A support base is installed at the bottom of each base, and a telescopic rod is installed at the top. A storage cavity is formed within the telescopic rod, and a storage box is fitted onto the outer wall of the telescopic rod. Fixing blocks are installed on both the left and right sides of the storage box's inner cavity. A clamping platform is installed on the front side wall of each fixing block, and a rotating shaft is inserted into the clamping platform. A diamond-shaped guardrail is installed between the rotating shafts on both sides. A clamping threaded post is screwed onto the front surface of the storage box. This invention, by incorporating the diamond-shaped guardrail, allows for quick pushing and pulling, switching between unfolded and retracted states. Furthermore, the storage cavity allows for clamping and fixing of the storage boxes on both sides, facilitating storage and transportation, reducing space occupation, and simplifying transport.
[0004] The aforementioned guardrails use a diamond-shaped structure to allow for extension and adjustment of their length. However, the disjointed connections between different guardrails mean they cannot be used continuously, leading to misalignment and gaps. Debris such as gravel can easily roll out from the guardrails onto other parts of the road, affecting vehicle traffic. Furthermore, highway construction generates a large amount of dust, creating a harsh working environment and hindering traffic flow. The aforementioned guardrails cannot effectively address these issues. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5This utility model provides a technical solution: a guardrail for road construction projects, including a first guardrail 1 and a second guardrail 2, the first guardrail 1 and the second guardrail 2 are attached to each other, the top of the first guardrail 1 and the second guardrail 2 are provided with water pipes 4, and a number of high-pressure atomizing nozzles 5 are fixed on the water pipes 4, and the two water pipes 4 are connected to each other.
[0025] Both the first guardrail 1 and the second guardrail 2 are made of PVC plastic. Grooves are provided on the opposite sides of the first guardrail 1 and the second guardrail 2. PVC plastic is lightweight, and the grooves reduce the overall weight, making it easy to carry and move. Both the first guardrail 1 and the second guardrail 2 are composed of vertical plates and trapezoidal bases distributed vertically. The trapezoidal bases are hollow. The inclined surface of the trapezoidal base has an inlet and an outlet near the top and front side, respectively. Both the inlet and outlet are threaded with caps 12. The vertical plates and the trapezoidal bases form a structure that is smaller at the top and larger at the bottom of the guardrail, which increases the contact area between the guardrail and the bottom surface, improves stability, and allows sand and water to be poured into the trapezoidal base through the inlet, thereby increasing the weight of the guardrail and preventing it from being blown away by the wind. The sand and water can be drained from the outlet. The caps 12 can seal the inlet and outlet.
[0026] A hinge 3 is movably connected between the first panel 1 and the second panel 2. The first panel 1 has a first slot on its left side, and the second panel 2 has a second slot on its left side. A connecting block 14 is movably connected in the second slot and is inserted into the first slot. A through hole is provided on the connecting block 14. An insert rod 16 is provided in the first slot and is inserted into the through hole. A cavity is provided on the first panel 1, and a screw 15 is movably connected in the cavity. The screw 15 is threadedly connected to the insert rod 16. A through hole is provided on the insert rod 16, and an internal thread is provided on the inner wall of the through hole. The screw 15 is inserted into the through hole and is threadedly connected to the through hole. A first knob 11 is connected to the front side of the screw 15. Two meshing bevel gears are provided in the cavity and are arranged perpendicular to each other. The screw 15 passes through the adjacent bevel gears. A connecting shaft is fixed on the other bevel gear and extends to the outside of the first panel 1 and is fixed to the first knob 11.
[0027] The first slot has an insertion hole on the side near the cavity. The insertion rod 16 is inserted into the insertion hole. The insertion rod 16 has sliders fixed on both the front and rear sides. The insertion hole has sliding grooves on both the front and rear sides that match the sliders to limit the insertion rod 16 and prevent the insertion rod 16 from rotating with the screw 15.
[0028] Several evenly distributed reflective strips 10 are affixed to both the first guardrail 1 and the second guardrail 2, which can warn vehicles on the road at night.
[0029] Fixed blocks 7 are fixed near the top of the first guardrail 1 and the second guardrail 2 on both sides, and sleeves 8 are fixed in the middle of each guardrail 1. The fixed blocks 7 have openings, and water pipes 4 pass through the sleeves 8, with both ends passing through adjacent openings. A ring 13 is fixed on the water pipe 4, located inside the sleeve 8. The ring 13 has several slots. A connecting rod 18 is threaded to the top of the sleeve 8, and a threaded hole is opened at the top of the sleeve 8. The outer wall of the connecting rod 18 has external threads, and a second knob 17 is fixed on the connecting rod 18. A hose 6 is connected between the two water pipes 4 near the hinge 3, and a rubber joint is fixed to the other end of each water pipe 4. A sealing end cap 9 is threaded to the rubber joint. The hose 6 ensures that the connection between the two water pipes 4 will not be broken when the first guardrail 1 and the second guardrail 2 are unfolded. The rubber joint makes the ends of the water pipes 4 flexible and able to bend to a certain extent, facilitating the connection of water pipes 4 between different guardrails. The sealing end cap 9 seals the ends of unconnected water pipes 4 to prevent water leakage.
[0030] Working principle: In use, place the barrier with the reflective strip 10 facing outwards around the construction site. Depending on the scope of the construction site, the barrier can be used in its folded state or unfolded. Turn the first knob 11, which drives the screw 15 to rotate through the bevel gear transmission, causing the insertion rod 16 to move into the insertion hole. Loosen the connecting block 14. At this time, the left side connection of the first barrier plate 1 and the second barrier plate 2 separates. Flip the first barrier plate 1 or the second barrier plate 2, and unfold the first barrier plate 1 and the second barrier plate 2 side by side in a straight line through the hinge 3, thereby increasing the length of the barrier. At the same time, multiple barriers can be combined after the first barrier plate 1 and the second barrier plate 2 are unfolded. When combining, insert the connecting block 14 on the upper barrier plate into the first slot of the lower barrier plate, and insert the insertion rod 16 into the through hole, thereby connecting the upper and lower positions. The isolation barriers are used to connect different barriers, facilitating a continuous enclosure and preventing large gaps caused by misalignment, which would affect the isolation effect. The cap 12 of the filling port can be opened to inject sand into the trapezoidal block cavity, thus increasing the weight of the barriers and preventing them from being blown away or toppled in strong winds. When retracting the barriers, the sand is emptied from the outlet. During use, the sealing cap 9 of one of the water pipes 4 is unscrewed and connected to an external water source pipe, allowing water to enter the pipe 4. Water mist is then sprayed outwards through the high-pressure atomizing nozzle 5 to reduce dust at the construction site and surrounding area. Turning the second knob 17 moves the connecting rod 18 away from the slot, allowing the water pipe 4 to rotate. This adjusts the angle of the high-pressure atomizing nozzle 5, thereby adjusting the spray angle and range of the water mist to avoid disturbing pedestrians.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
