Description

Steel corrugated pavement anti-slip and supporting device Technical Field The utility model belongs to the technical field of steel corrugated tunnel anti-slip, and particularly relates to a steel corrugated tunnel anti-slip and supporting device. Background In traffic infrastructure construction, road culvert engineering has a key role. Currently, reinforced concrete is mainly used as a building material for arch culverts, and the construction technology is relatively mature. However, the construction period of the reinforced concrete culvert is long, and a crack problem easily occurs in the use process. In addition, due to the large dead weight of the structure, problems such as foundation settlement and the like can be caused. In view of the numerous difficulties in reinforcing and repairing culverts of reinforced concrete structures, the economics and applicability thereof are therefore limited. In contrast, the corrugated steel structure culvert is formed by connecting or assembling corrugated pipes or arc plates, and a more flexible and efficient solution is provided. By using the corrugated steel structure, construction can be performed under changeable climatic conditions, and adverse effects of bad weather such as rain and snow on engineering quality and construction progress are effectively reduced. In addition, the construction of the corrugated steel structure shows remarkable flexibility, so that the corrugated steel structure can be designed and laid out more flexibly according to the on-site topography characteristics and engineering actual requirements. The corrugated steel structure also has excellent tensile, shearing and fatigue resistance, and further ensures the stability and durability of engineering. However, in the face of steep terrain tunnels, heavy transport vehicles can deliver significant horizontal thrust to tunnels at the moment of start and brake. At this time, corrugated steel pipe tunnels are not very attractive in terms of anti-slip, and this problem is common in engineering practice. Therefore, the anti-slip performance of the corrugated steel pipe has to be improved to ensure that it can cope with challenges of complex terrain, thereby enhancing the safety and reliability of the corrugated steel pipe.
