Leakage Prevention and Noise Reduction Bridge Connections
Core Technologies and Features
· Wheel ground surface is steel, has excellent water resistance, prevents damage to the structure, and is a flexible structure that can be recycled
· Development of a "steel saw-blade expansion joint" that is excellent in driving and durability and can prevent damage to the substructure by preventing rainwater from flowing into the substructure
① Leakage Prevention : Formation of longitudinal tight protrusions on the side of a sealed double waterproof sheet
· The outer wall of the support sheet is characterized by a horizontal contact protrusion protruding from a number of locations with different heights in order to improve the airtightness with the main body x-frame
→ Improved airtightness, water leakage, noise reduction
② Assembly-type fixing structure (assembly-type structure that can be constructed separately by lane) : Steel and rubber seal-type fixing bracket structure
· A support tool for supporting the head of the fastening bolt is inserted into the support sheet
→ Resource recycling, joint leakage prevention, segmentation by lane
③ Prevention of damage and noise reduction of rear concrete: The upper slab connection part is uneven
· The upper plate is characterized by the uneven shape of the upper slab connection part to improve the drivability of the vehicle and prevent damage to the upper slab
· Use a saw blade to attach wings to the extension joint joined to the rear concrete
To prevent damage to the concrete by distributing the impact of the vehicle wheels on the joint surface of the concrete
(Effect of reducing impact force by less than about ½ compared to existing products)
→ Prevent damage to concrete and ensure durability
Use (Construction) Method
Road surface cutting → concrete breaking → BLOCK OUT → BACKUP REinstallation → MS JOINT Lateral Reinforcement → MS JOINT connection assembly → MS JOINT mounting → MS JOINT taping → concrete pouring → surface mash finish → curing → completion of curing and curing
