Suspension tunnel with live load balancing chamber

WANG SHUSHENG

The invention discloses a floating tunnel with live load balancing chambers, which is characterized in that the floating tunnel comprises a foundation, a tunnel pipe joint and a connecting device, the foundation is connected with the tunnel pipe joint through the connecting device, the tunnel pipe joint comprises a plurality of live load balancing chambers, and the live load balancing chambers are arranged along the length direction of the floating tunnel; the live load balancing chamber is provided with a hole communicated with an external water area, a compressed air pipeline is arranged in the live load balancing chamber, and the water volume in the live load balancing chamber is adjusted by adjusting the pressure of compressed air in the live load balancing chamber so as to dynamically balance the change of the live load borne by the floating tunnel. The method has the advantages that the resultant force of the floating tunnel where each live load balancing chamber is located in the vertical direction is zero by adjusting the water amount of each live load balancing chamber; and the foundation is low in construction cost, short in construction period and environment-friendly.

本发明公开了一种有活载平衡室的悬浮隧道，其特征是该悬浮隧道包括基础、隧道管节和连接装置，基础通过连接装置与隧道管节相连，隧道管节包括活载平衡室，若干活载平衡室沿悬浮隧道的长度方向布置；活载平衡室设有联通外部水域的孔，活载平衡室内包括压缩空气管路，通过调整活载平衡室内压缩空气的压力，来调整活载平衡室内的水量，以动态平衡悬浮隧道所受活载的变化。本发明的优势是：通过调整各活载平衡室的水量，实现各活载平衡室所处悬浮隧道在铅直方向的合力为零；基础建造成本低、施工周期短且环保。
