More Information
Summary:The invention discloses an anti-floating reinforcing system for a drainage cross beam and a drainage reinforcing wall between underlying sandy soil piles of a seabed immersed tunnel. The reinforcing system comprises gravel piles, inter-pile drainage cross beams, drainage reinforced concrete reinforcing walls, a gravel hardcore, a backfill layer and an immersed tunnel. The gravel piles are vertically arrayed in the liquefiable sand foundation by a compaction method; a through hole is formed in the gravel pile, and a welding sleeve is mounted in the through hole; the drainage reinforced concrete reinforcing walls stand on the two opposite sides of the gravel pile array, hole sites are reserved, and welding sleeves are installed on the drainage reinforced concrete reinforcing walls. The inter-pile drainage cross beam penetrates through the welding sleeve of the gravel pile, and the two ends of the inter-pile drainage cross beam are connected to the welding sleeve of the drainage reinforced concrete reinforcing w
