Description

Technical Field

[0001] The utility model relates to the technical field of cable trench covers, in particular to a high-performance fiber concrete cable trench cover for a highway tunnel. Background Art

[0002] High-performance fiber concrete has strong fluidity and exerts greater pressure on the formwork than ordinary concrete. The pressure on the opposite side of the formwork should be verified according to the fluid pressure. The formwork should be sealed to prevent expansion and leakage. A release agent should be applied to the surface where the formwork contacts the high-performance fiber concrete. When encountering narrow spaces, chamfers, or cross-sectional changes in the formwork, a hydrophobic material sheet (such as an acrylic sheet or a PVC sheet) can be used as an inner lining on the inside of the formwork to improve the appearance quality of the high-performance fiber concrete. The cover plate installation area is above the cable trench of tunnels and other projects, and is used for pedestrian inspection roads or tunnel crosswalks.

[0003] The cover plate is mainly used to cover and shield the cable trench, preventing pedestrians and cars from falling from the cable trench and causing danger. The cover plates can be spliced ​​with each other to increase the coverage of the cable trench, but the number of cover plates is relatively large. When the surface of the cover plate is worn, the corresponding cover plate needs to be replaced in time. However, the cover plates are relatively firm and have almost no gaps. There are no good stress points on the surface of the cover plate, so the cover plate cannot be removed quickly, reducing the efficiency of replacing the cable trench cover plate. Therefore, it is particularly important to design high-performance fiber concrete cable trench covers for highway tunnels. Utility Model Content
