Construction method of immersed tube joint in immersed tube tunnel and immersed tube joint structure
The invention relates to a construction method of an immersed tube joint in an immersed tube tunnel and an immersed tube joint structure. A sleeve head sleeves one end of each immersed tube, and a grouting pipe is arranged on at least one end of each immersed tube in advance. After pre-operation, all the immersed tubes are sequentially sunk into underwater preset positions at intervals end to end, so that the end, with the sleeve head, of one immersed tube is opposite to the end, without the sleeve head, of the other immersed tube; then in any two adjacent immersed tubes, the end, without the sleeve head, of one immersed tube is connected into the sleeve head in a sleeved mode, so that the two immersed tubes are mutually spliced in the same sleeve head; after splicing, pressure grouting is conducted between every two adjacent immersed tubes through a grouting pipe, so that the immersed tubes are tightly combined under the action of concrete grout; and after pressure grouting is full, edge sealing treatment is conducted between the sleeve head and the two immersed tubes, so that gaps between the sleeve head and the immersed tubes are blocked. The construction method has the advantages of high construction splicing precision, convenience in construction and difficulty in water leakage after operation.
本发明涉及一种沉管隧道中沉管接头施工方法及沉管接头结构，在每个沉管的一端均套接有套头；在每个沉管的至少一端上预设注浆管。预操作后，将所有的沉管首尾顺次间隔沉入至水下预设位置上，使得一个沉管上具有套头的一端与另一个沉管上不具有套头的一端相对；接着，在任一相邻两个沉管中，将一个沉管上不具备套头的一端套接在套头内，使得两个沉管在同一套头中完成相互拼接；拼接后，通过注浆管向相邻两个沉管之间压力注浆，使得沉管与沉管之间在混凝土浆作用下紧密结合；当压力注浆饱满后，对套头与两个沉管之间进行封边处理，以实现套头与沉管之间间隙封堵。本施工方法施工拼接精度高，施工方便，运营后使用不易漏水。
