Intelligent waterproof and anti-seismic immersed tunnel pipe joint
The invention provides an intelligent waterproof anti-seismic immersed tunnel pipe joint which comprises an intelligent displacement sensor which is installed in an installation hole of a joint part and can monitor abnormal displacement in a tunnel in real time. The embedded clamping grooves are uniformly distributed at the joint part; and the adjusting units are in one-to-one correspondence with the positions of the embedded clamping grooves. And the adjusting unit is connected with the pre-embedded clamping groove, after installation is completed, the adjusting rod and the pre-embedded clamping groove are pre-tensioned through the adjusting motor and the electric jack, the integrity of the pipe joint can be effectively improved, and then the overall anti-seismic capacity of the immersed tunnel is improved. And the control unit can give an alarm in time when the deformation exceeds the allowable displacement threshold data. Once the deformation exceeds the allowable displacement threshold data, the calculation module can be automatically started to calculate the adjustment value, and the control module and the adjustment unit are controlled to complete automatic adjustment and increase the tensile stress between the sections at the abnormal displacement, so that the waterproof requirement is ensured.
本发明提供了一种智能防水抗震的沉管隧道管节，包括智能位移传感器，安装于接头部位的安装孔内，能够对隧道中的异常位移进行实时监控；预埋卡槽设置在接头部位均匀分布；调节单元与预埋卡槽的位置一一对应。调节单元与预埋卡槽进行连接，在安装完毕后，通过调节电机和电动千斤顶将调节杆和预埋卡槽之间进行预拉紧，能够有效的提高管节的整体性，进而提升沉管隧道整体的抗震能力。控制单元能够在形变超出容许位移阈值数据时及时进行报警。一旦形变超过容许位移阈值数据，能够自动启动计算模块，计算出调节数值，并通过控制控制模块和调节单元完成自动调节，加大异常位移处节段与节段之间的拉应力，从而保证防水要求。
