Seabed immersed tunnel damping and drainage reinforcing system and construction method thereof
The invention relates to the field of seafloor immersed tube tunnel sand foundation anti-liquefaction reinforcement engineering, and particularly discloses a seafloor immersed tube tunnel damping drainage reinforcement system and a construction method thereof, and the reinforcement system comprises a gravel foam pile, a gravel foam plate and a gravel foam wall; the gravel foam piles are embedded in a seabed sand foundation below the immersed tunnel in an array mode, the gravel foam plate covers the bottom of the foundation trench and is arranged between the immersed tunnel and the gravel foam piles, and the two gravel foam walls are vertically embedded in the seabed sand foundation and located on the two sides of the gravel foam pile array respectively. Tie pieces are connected between the immersed tube tunnel and the gravel foam wall on the same side, the two sides of the immersed tube tunnel are filled with damping backfill layers, and the upper portions of the damping backfill layers and the immersed tube tunnel are filled with block stone backfill layers. The method has the advantages of being easy, convenient and rapid to construct, high in bearing capacity, high in sand liquefaction resistance and high in shock resistance.
本申请涉及海底沉管隧道砂土地基抗液化加固工程领域，具体公开了一种海底沉管隧道减震排水加固体系及其施工方法，加固体系包括碎石泡沫桩、碎石泡沫板和碎石泡沫墙，多个碎石泡沫桩呈阵列式埋置于沉管隧道下方的海底砂土地基中，碎石泡沫板覆盖于基槽底部且设置于沉管隧道与碎石泡沫桩之间，两个碎石泡沫墙竖直埋置于海底砂土地基中且分别位于碎石泡沫桩阵列的两侧；沉管隧道与同侧的碎石泡沫墙之间连接有拉结件，沉管隧道的两侧填充有减震回填层，减震回填层和沉管隧道的上方填充有块石回填层。本申请具有施工简便快捷、承载力高、抗砂土液化能力强以及抗震能力强的效果。
