4. Key Features & Benefits
①Heavy-Duty Formwork Configurations
Steel frame panels, engineered brackets and anchoring components can be configured for large concrete sections and demanding hydraulic construction conditions.
②Formwork Options for Water-Retaining Structures
Single-side formwork arrangements can be considered where through-ties are restricted, helping contractors plan concrete walls with fewer potential tie-hole penetrations.
③Adaptable to Staged Concrete Pouring
Cantilever climbing formwork supports successive concrete lifts for tall walls and dam structures, with bracket and anchoring configurations developed around the pouring sequence.
④Customized Structural Geometry
Formwork layouts can be adapted for straight walls, inclined faces, openings and other project-specific hydraulic concrete structures.
⑤Integrated Engineering & Supply
Songmao provides panel layout drawings, quantity calculations, customized components and compatible support systems to simplify procurement and construction planning.
5. Engineering Challenges & Solutions
Mass Concrete Placement
Dam construction often involves large concrete sections and successive pouring stages. Songmao configures formwork panels, brackets and supporting components according to pour dimensions, concrete pressure and construction sequences.
Water-Retaining Structures
Water-retaining walls may require restrictions on through-tie penetrations. Where appropriate, single-side formwork and engineered anchoring arrangements can be evaluated to meet the project’s structural and waterproofing requirements.
Inclined & Irregular Concrete Surfaces
Spillways, intake structures and dam faces may include inclined or nonstandard profiles. Customized formwork layouts help accommodate these geometries while maintaining the required concrete dimensions.
High Walls & Successive Concrete Lifts
For tall concrete structures, cantilever climbing formwork can support staged construction. Brackets, anchors and working platforms must be designed for the selected lifting method, structural conditions and construction loads.
Temporary Support for Powerhouse Structures
Hydropower powerhouse buildings may require wall, column, beam and slab formwork in combination with shoring towers or adjustable steel props. Integrated system planning helps coordinate different concrete construction stages.
