Immersed tunnel pushing type final joint device and construction method
The invention discloses an immersed tunnel pushing type final joint device and a construction method. The device comprises a foundation bed, an expansion section arranged on the foundation bed, a connecting section and a pushing-out section. The front end of the expansion section is provided with an expansion end, the push-out section is arranged in the expansion end, and a pushing jack is arranged between the expansion section and the push-out section; an expansion section end sealing door is arranged at the rear end of the expansion section, a push-out section end sealing door is arranged in the push-out section, a cavity is formed between the expansion section and the push-out section, and a water injection system is connected to the cavity. The water injection system comprises a water injection pipe, a water injection tank, a pressure regulating pipe and a water outlet pipe, the water injection pipe is connected with the water injection tank and the cavity, one end of the pressure regulating pipe is connected with the cavity, and the other end of the pressure regulating pipe penetrates out of the water surface; the pushing jacks are divided into two sets which are the same in number and arranged in a staggered mode, water is injected into the cavity through the water injection system to balance water pressure on the two sides of the push-out section end sealing door, and the push-out section is pushed out to be connected with the connecting section through the pushing jacks.
本发明公开了一种沉管隧道顶推式最终接头装置及施工方法，装置包括：基础垫层、设于基础垫层上的扩大段、连接段以及推出段；扩大段的前端设有扩大端，推出段设于扩大端内，二者之间设有顶推千斤顶；扩大段后端设有扩大段端封门，推出段中设有推出段端封门，使扩大段与推出段间形成空腔，空腔上连接有注水系统；注水系统包括注水管、注水水箱、调压管以及出水管，注水管连接注水水箱和空腔，调压管一端与空腔相连，另一端穿出至水面以上，出水管连接空腔和外界水，注水水箱设于扩大段的后端；顶推千斤顶分为数量相同且交错设置的两组，通过注水系统往空腔中注水以平衡推出段端封门两侧的水压，结合顶推千斤顶将推出段推出至与连接段连接。
