Description
Technical Field
The invention relates to the technical field of sand filling of immersed tube tunnel pipe sections, in particular to a special engineering ship for foundation sand filling of an immersed tube tunnel.
Background
The immersed tube tunnel is an underwater tunnel which is built by the working procedures of prefabrication in a dock, towing floating, sinking and docking, foundation treatment, backfilling and covering of tube sections and the like. The top of the tunnel is shallow in earthing, short in tunnel length and more flexible in connection with roads on two sides of a water area, so that land resources in a central urban area can be greatly saved, and the tunnel is one of main methods for constructing underwater tunnels of inland rivers in cities. However, the inland river has the disadvantages of narrow river channel, shallow water, large flow velocity, dense shipping and large water level drop, brings great difficulty to floating and sinking of pipe sections, even affects construction safety, dense water construction structures such as river-crossing bridges and the like, and also limits the use of large-scale offshore floating and sinking equipment. The sinking pipe tunnel with the sinking ratio of more than 80 percent eliminates the harmful gaps of the bottom surface of the pipe joint and the bottom of the base groove through the sand filling cushion layer after the pipe section is sinking, but the traditional sand filling method has the following problems: 1. the sand material is separated from the sand filling ship, sand filling is discontinuous, so that the construction efficiency is low, the construction time is long, and the difficulty in selecting the window period of the immersed tube scheme is increased; 2. the control of main indexes such as sand filling pressure, sand filling quantity and the like in sand filling construction is mainly carried out empirically. 3. After the construction is completed, the shape, filling effect and the like of the sand disc are not known, and no effective detection means exists. 4. The later sand filling hole has high hole sealing difficulty and is easy to produce the structure water leakage condition. Because the sand filling quality cannot be accurately mastered, the later settlement of the pipe sections is difficult to predict (calculate) after sand filling is finished, and uneven settlement among the pipe sections of the immersed tunnel is caused, so that the risk of water leakage of pipe section joints is caused, and the operation safety of the tunnel is endangered.
