Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a tunnel segment mould structure. Background Art

[0002] The shield segment is the main assembly component of the shield construction and the innermost barrier of the tunnel. It is responsible for resisting soil pressure, groundwater pressure and some special loads. The shield segment is the permanent lining structure of the shield tunnel. The quality of the shield segment is directly related to the overall quality and safety of the tunnel, and affects the waterproof performance and durability of the tunnel.

[0003] In the prior art, shield segments, also known as tunnel segments, are the main assembly components of shield construction, and the quality of shield segments is directly related to the overall quality and safety of the tunnel. In the process of producing shield segments, molds are needed, and shield segments are obtained by casting and molding in the molds. After the shield segments are formed, they need to be separated from the shield segment molds. The shield segments themselves are heavy, so mold separation is very difficult. In addition, during the mold separation process, if the force is uneven when separating the molds, it is easy to cause damage to the shield segments, thereby resulting in unqualified quality of the shield segments. Therefore, we propose a tunnel segment mold structure. Utility Model Content
