Construction method of land joint of river-crossing channel
The invention relates to the technical field of river-crossing immersed tunnel construction, in particular to a river-crossing channel land joint construction method, which is characterized in that a final joint of a river-crossing channel is converted to a joint of an immersed tunnel and an ashore tunnel, so that the immersed tunnel is convenient to lay, and the immersed tunnel can be laid from a south shore side to a north shore side firstly; the end, close to the dry dock, of the immersed tunnel is located in a dock entrance, the dock entrance is sealed through a steel cofferdam, the end, close to the dry dock, of the immersed tunnel is located on the dry dock side of the steel cofferdam, then drainage is conducted in the dry dock, and a dry construction environment is formed in the dry dock; and then final joint construction between the first ashore tunnel and the immersed tube tunnel is conducted, so that the final joint of the river-crossing channel is constructed in the dry construction environment, the engineering construction difficulty of the immersed tube of the river-crossing channel and the final joint of the ashore tunnel is effectively reduced, meanwhile, under the dry construction condition, the potential safety hazard problem of underwater construction can be effectively avoided, and the construction efficiency is improved. And the construction precision and quality can be ensured.
本发明涉及跨江沉管隧道建设技术领域，特别涉及一种跨江通道陆上接头的施工方法，将跨江通道的最终接头转换至沉管隧道与岸上隧道的接头处，从而便于沉管隧道的铺设，使沉管隧道能够先从南岸侧铺设至北岸侧，加快了沉管隧道施工进度，沉管隧道靠近干坞的一端位于坞口内，通过钢围堰对坞口进行封闭，使沉管隧道靠近干坞的一端位于钢围堰的干坞侧，然后对干坞内进行排水，使干坞内形成干施工环境，再进行第一岸上隧道与沉管隧道之间的最终接头施工，从而在干施工环境下施工跨江通道的最终接头，有效减少跨江通道的沉管和岸上隧道最终接头工程建设难度，同时在干施工条件下，不仅可以有效避免水下施工安全隐患问题，还可以保证施工精度质量。
