Construction method of flexible anti-seismic joint of immersed tunnel
The invention provides a construction method of a flexible anti-seismic joint of an immersed tunnel, and relates to the technical field of engineering construction. The construction method of the flexible anti-seismic joint of the immersed tunnel comprises the following specific steps that S1, firstly, an immersed foundation trench after river bottom dredging is accurately measured, the flatness, the gradient and the size width of each position of the foundation trench are repeatedly confirmed, and an immersed pipe section can be accurately immersed into a designated installation position in the pipe immersing process; and S2, the pipe section subjected to watertight detection is subjected to floating transportation by utilizing a floating pontoon, and after the floating pontoon reaches the designated position, a floating pontoon operator can accurately position the immersed pipe position of the pipe section again according to positioning information sent by an underwater diver. The pipe section is connected and fixed by adopting a flexible steel cable, and a connecting part is subjected to over-sealing treatment through pressing of a waterproof pad and a waterproof ring, so that the firmness and the stability of pipe section connection can be ensured, meanwhile, high-quality sealing treatment can be realized, and the situation of leakage is prevented.
本发明提供沉管隧道柔性抗震接头施工方法，涉及工程建筑技术领域。该沉管隧道柔性抗震接头施工方法，包括以下具体步骤：S1.首先对河底浚挖后的沉管基槽进行精确测量，反复确认基槽各个位置的平整度、坡度以及尺寸宽度，确保沉管管段在沉管的过程中能够精确沉入指定安装位置；S2.将经过水密检测后的管段利用浮船进行浮运，在浮船到达指定位置后，浮船操作人员可以根据水下潜水员发出的定位信息对管段的沉管位置进行再次精确定位。通过采用柔性钢索对管段进行连接固定，并通过防水垫和防水圈的压合来对连接部进行过密封处理，既可以确保管段连接的牢固性与稳定性，同时也能实现高质量的密封处理，防止出现渗漏的情况。
