Description

Technical Field

[0001] The utility model relates to the technical field of construction of roller compacted concrete hyperbolic arch dams, in particular to a bidirectionally adjustable lifting template for roller compacted concrete hyperbolic arch dams. Background Art

[0002] As we all know, a hyperbolic arch dam is an arch dam that is curved in both directions (horizontally and vertically). It is the most representative type of arch dam. The horizontal curvature of the hyperbolic arch dam can play the role of an arch, and the vertical curvature can achieve variable center and variable radius to adjust the curvature and radius of the upper and lower parts of the arch dam.

[0003] Roller-compacted concrete is a dry, hard, cement-poor concrete that uses silicate cement, volcanic ash admixtures, water, admixtures, sand and graded coarse aggregate to mix into dry, hard concrete without slump. It uses the same transportation and paving equipment as earth-rock dam construction and is compacted layer by layer with a vibrating roller. Roller-compacted concrete dams have the characteristics of small concrete volume, high strength, good anti-seepage performance, and overflow of the dam body. They also have the advantages of simple, fast, economical construction procedures for earth-rock dams, and the use of large general-purpose machinery. The construction of hyperbolic arch dams cannot do without roller-compacted concrete.

[0004] When using roller compacted concrete to build a hyperbolic arch dam, several formworks are needed to cooperate. In order to meet the shape and construction requirements of the hyperbolic arch dam, the formworks need to be designed to be bidirectionally adjustable. However, the formworks currently used in this field have more parts in the adjustment structure, which is relatively complicated to operate and difficult to adjust to the desired accuracy. Therefore, a bidirectionally adjustable flip formwork for a roller compacted concrete hyperbolic arch dam is proposed. Utility Model Content
