Bridge abutment formwork

The applicable scenarios for bridge abutment templates include: 1) Bridge engineering ① Highway bridges Used for pouring concrete at the bridge abutment to ensure stable connection between the abutment, bridge pier, and roadbed, and to enhance the overall bearing capacity and deformation resistance of the bridge. Suitable for scenarios such as highways and urban expressways, it must meet high load and long-term durability requirements. ② Railway Bridge In the construction of railway bridge piers, steel formwork or composite formwork is used to ensure the accuracy of concrete structures and meet the high-frequency vibration and long-term safe operation requirements of trains. ③ Elevated bridges and overpasses Used for cast-in-place construction of bridge piers, combined with pier column formwork to form a continuous stress system, to prevent settlement or cracking problems caused by uneven stress on bridge piers. 2) Special structures and complex scenes ① Design of irregular bridge piers: Accurate shaping of curved and multi angle bridge piers is achieved through adjustable steel formwork, meeting the requirements of special bridge design. ② Complex terrain construction: In mountainous areas, slopes, or soft soil foundations, the bridge abutment formwork needs to adapt to irregular terrain to enhance the stability of the connection between the bridge and the foundation. 3) Other engineering fields ① Water conservancy engineering: In the construction of bridge abutment structures for some water conservancy facilities (such as water gates and dams), templates need to be used to ensure the quality of concrete pouring. ② Prefabricated bridge abutment production: Standardized steel formwork can be used to prefabricate bridge abutment components in batches, improving construction efficiency and reducing on-site operational risks. 4) Construction characteristics and technical requirements ① Core tools for cast-in-place construction The template needs to have high strength and high sealing (such as using sponge strips to prevent leakage at joints) to ensure the dimensional accuracy and surface quality of the concrete after molding. ② Reuse and Economy The steel bridge abutment formwork can be disassembled and reused, reducing construction costs and minimizing resource waste. Note: The core application scenario of bridge pier formwork is the construction of bridge piers for various types of bridges, especially suitable for engineering projects that require high precision, high stability, and complex structural formation.
