Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel engineering equipment, and in particular relates to a variable-section trolley commonly used in a tunnel avoidance section and a main tunnel. Background Art

[0002] In my country, longer tunnels are all equipped with emergency parking strips, also known as avoidance sections. There is an extra lane, which is used for the safety of parking the car when a malfunction occurs after the car enters the tunnel. In this case, a tunnel will have two sections with large differences. In the past, when lining the tunnel, a back mold was generally added to the main tunnel trolley, or the portal was widened and a whole set of top molds were replaced. In this way, some parts of the main tunnel trolley were shared, which was more economical. However, after lining a avoidance section, it was necessary to change back to the main tunnel trolley and then change back to the next avoidance section. Each replacement took a long time and consumed a lot of manpower. Later, a avoidance section trolley appeared in the industry, which only lined the avoidance section. After lining the avoidance section, the trolley was reduced to the size of passing through the main tunnel, and then went to the next avoidance section to participate in the lining of the next avoidance section. This trolley can only line the avoidance section, not the main tunnel, and is only suitable for tunnels with more avoidance sections. The economy of this solution is not as good as the previous one.
