Seabed immersed tunnel drainage anti-floating reinforcing system and construction method thereof
The invention relates to a drainage anti-floating reinforcing system for a seabed immersed tunnel and a construction method thereof.The reinforcing system comprises a plurality of permeable layers which are buried in a sand foundation below the seabed immersed tunnel in an array mode and used for forming a drainage channel in the transverse direction; the plurality of water permeable columns are distributed between the upper and lower adjacent water permeable layers and are used for conducting water permeable conduction on the adjacent water permeable layers in the vertical direction; the water drainage piles are distributed on the two sides of the seabed immersed tube tunnel at intervals in the extending direction of the seabed immersed tube tunnel and used for conducting water permeable communication between the water permeable layers and a backfill layer on the periphery of the immersed tube tunnel, and the two ends of the water permeable layers located on the same vertical face are correspondingly connected with the left and right adjacent water drainage piles; the tops of the drainage piles are connected with the backfill layer. The water drainage structure of the sand liquefaction foundation is composed of the water permeable layer, the water permeable columns and the water drainage piles, so that the problems that in the prior art, transverse water drainage of the sand liquefaction foundation is not smooth, and vertical water drainage is limited are solved.
本发明涉及一种海底沉管隧道引流抗浮加固系统及其施工方法，上述加固系统包括若干透水层，阵列式的埋设于海底沉管隧道下方的砂土地基中，用于在横向方向上形成排水通道；若干透水柱，分布于上、下相邻的透水层之间，用于在竖向方向上将相邻透水层进行透水导通；以及若干排水桩，沿海底沉管隧道的延伸方向间隔式的分布于海底沉管隧道两侧，用于将透水层与沉管隧道外围的回填层进行透水导通，位于同一竖向面上的若干透水层的两端对应与与左、右相邻的排水桩相连，排水桩的顶部与回填层相连。本发明中利用透水层、透水柱和排水桩组成砂土液化地基的排水结构，以改良现有技术中存在的砂土地基的横向排水不畅通，以及竖向排水存在局限性的问题。
