Description

Technical Field

[0001] This utility model belongs to the field of road engineering technology, and in particular relates to a fiberglass grating cover plate for highway tunnels that is resistant to frost expansion. Background Technology

[0002] Roads are transportation infrastructure that allows various vehicles and pedestrians to pass. Road construction brings convenience to people's travel, shortens the time it takes to reach their destination, and reduces road surface roughness, greatly increasing driving comfort and safety. There are many types of roads: urban roads, forest roads, rural roads, and highways. During the construction of highways, to shorten distances and avoid complex mountain roads, tunnels are often built to directly pass through mountains, thus avoiding long stretches of winding mountain roads. Furthermore, to drain rainwater from the tunnel surface, drainage ditches are dug and covered with fiberglass grating.

[0003] However, fiberglass grating covers still have the following drawbacks in actual use:

[0004] 1. Drainage ditches are dug on the ground of highway tunnels. To prevent large debris from entering the drainage ditches, limiting grooves are made in the drainage ditches, and fiberglass grating covers are laid inside the limiting grooves. Water on the ground of the highway tunnel enters the drainage ditch through the through holes in the fiberglass grating covers. However, water on the ground of the highway tunnel will also enter the limiting groove through the gap between the fiberglass grating covers and the drainage ditch. Since the limiting groove is a flat structure, it is difficult to completely drain the water inside the limiting groove. The water will freeze due to low temperature, and may even cause the fiberglass grating covers to freeze and crack, reducing the service life of the fiberglass grating covers.

[0005] 2. Dust is unavoidable on the surface of highway tunnels. When water from the highway tunnel surface enters the limiting groove, dust will also enter the limiting groove with the water flow. As the dust inside the limiting groove increases, when the sewage inside the limiting groove enters the drainage ditch through the drainage mechanism, silt will remain inside the drainage mechanism. As the silt inside the drainage mechanism increases, it will cause blockage, resulting in slow drainage of water inside the limiting groove and reducing the frost resistance of the FRP grating cover.

[0006] To address these issues, we offer fiberglass grating covers for highway tunnels to prevent frost expansion. Utility Model Content

[0007] The purpose of this utility model is to provide a frost-resistant fiberglass grating cover for highway tunnels. By setting up a fiberglass grating cover assembly, the drainage pipe discharges the water accumulated inside the limiting groove, preventing the fiberglass grating cover assembly from freezing and expanding due to low temperature, thus extending the service life of the fiberglass grating cover assembly. In addition, by setting up a sludge removal component, the sludge inside the drainage pipe is cleaned, and the water accumulated inside the limiting groove is discharged more efficiently, improving the frost resistance effect, thereby solving the technical problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model relates to a frost-resistant fiberglass grating cover for highway tunnels, comprising a drainage ditch in the highway tunnel, a limiting groove on the drainage ditch, and a fiberglass grating cover assembly on the drainage ditch. The fiberglass grating cover assembly includes drainage pipes symmetrically fixed to the lower surface of an outer frame, the outer frame being located inside the limiting groove, and the drainage pipes being inclined. A sludge-clearing assembly is located inside the drainage pipe, comprising a guide rod fixed to the top of the drainage pipe, and a scraper located inside the drainage pipe. The upper surface of the scraper has a sliding groove slidably connected to the guide rod, and a protruding handle is fixed to the side wall of the scraper.

[0010] The present invention is further configured such that a strip plate one is fixedly connected at equal intervals along the length direction inside the outer frame, and a strip plate two is fixedly connected at equal intervals along the width direction inside the outer frame.

[0011] The present invention is further configured such that reinforcing ribs are fixedly connected at equal intervals on the upper surface of the drain pipe, and the upper end of the reinforcing ribs is fixedly connected to the lower surface of the outer frame.

[0012] The present invention is further configured such that a support plate is fixedly connected to the lower surface of the drain pipe, and the lower surface of the support plate is installed on the inner bottom of the limiting groove.

[0013] The present invention is further configured such that the support plate has a triangular structure, and the bottom dimension of the support plate is equal to the inner bottom dimension of the limiting groove.

[0014] The present invention is further configured such that a limiting plate is fixedly connected to the side wall of the drain pipe, and the limiting plate abuts against the side wall of the scraper.

[0015] The present invention is further configured such that the distance between the end of the guide rod and the inner wall of the drain pipe is equal to the thickness of the scraper.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting up a fiberglass grating cover assembly, allows water that enters the limiting groove through the gap between the highway tunnel drainage ditch and the outer frame to enter the interior of the drainage pipe. The water inside the drainage pipe is then discharged into the highway tunnel drainage ditch. The inclined design of the drainage pipe can improve the discharge efficiency of water accumulated in the limiting groove, avoid freezing and swelling of the fiberglass grating cover assembly due to low temperature, and extend the service life of the fiberglass grating cover assembly.

[0018] 2. This utility model, by setting up a dredging component, uses clamps to clamp the fiberglass grating cover assembly, removes the fiberglass grating cover assembly from the highway tunnel ditch, pushes the scraper, and the scraper moves along the guide rod inside the drain pipe to clean the silt inside the drain pipe, prevents the drain pipe from being blocked, discharges the water inside the limiting groove more efficiently, and improves the anti-freezing expansion effect.

[0030] Specifically, a limiting groove 101 is provided on the drainage ditch 1 of the highway tunnel, and a drainage pipe 202 is symmetrically fixed to the lower surface of the outer frame 201. The drainage pipe 202 is set at an inclination.

[0031] Furthermore, strip plates 201a are fixedly connected at equal intervals along the length direction inside the outer frame 201, and strip plates 201b are fixedly connected at equal intervals along the width direction inside the outer frame 201.

[0032] The operation process of this embodiment is as follows: water that falls into the limiting groove 101 through the gap between the highway tunnel water ditch 1 and the outer frame 201 enters the interior of the drain pipe 202, so that the water inside the limiting groove 101 enters the interior of the highway tunnel water ditch 1 through the drain pipe 202.

The scraper 301 is pushed and moves along the guide rod 303 inside the drain pipe 202 to clean the silt inside the drain pipe 202, so that the drain pipe 202 can discharge the water inside the limiting groove 101 more efficiently and increase the anti-freezing expansion effect. The limiting plate 302 is used to prevent the scraper 301 from detaching from the drain pipe 202.

[0035] Specifically, the scraper 301 is located inside the drain pipe 202. The upper surface of the scraper 301 is provided with a groove 301b.
