Immersed tube tunnel tube segment gravity anchor
The invention discloses an immersed tube tunnel tube segment gravity anchor, and belongs to the technical field of immersed tube tunnel tube construction. The immersed tube tunnel tube segment gravityanchor comprises an anchor block. The top of the anchor block is connected with two groups of symmetrically-arranged lifting rings, the anchor block is of a hollow structure, the interior of the anchor block is connected with a movable box, a piston is slidingly connected to the inner side wall of the movable box, an air airbag is connected into the movable box, an air inlet of the air airbag isconnected with an air compressor, the bottom of the anchor block is connected with a supporting plate, the bottom of the piston penetrates through the movable box and the bottom of the anchor block tostretch outwards, and an elastic reset part is connected between a pressing plate and the supporting plate. The contact area of the piston and the sea bed can be increased, the counter acting force of the piston is improved, the piston is prevented from being inserted into mud, and it is not needed to inject water into the anchor block through an embedded steel pipe to drive the piston to be reset.
本发明公开了一种沉管隧道管段重力锚，属于沉管隧道管施工技术领域，一种沉管隧道管段重力锚，包括锚块，锚块的顶部连接有两组对称设置的吊环，锚块的内部为中空结构，锚块的内部连接有活动箱，活动箱的内侧壁上滑动连接有活塞，活动箱内部连接有空气气囊，空气气囊的进气口与空气压缩机相连，锚块的底部连接有支撑板，活塞的底部穿过活动箱与锚块的底部向外延伸，压板与支撑板之间连接有弹性复位件；本发明可以提高活塞与海底接触面积提高活塞反向作用力，防止活塞插进淤泥内部，并且不需要再通过预埋钢管对锚块内部注水带动活塞归位。
