Problems solved by technology
However, this method has the following defects: on the one hand, because the end panel material Q390C is sensitive to temperature, the embedded parts are welded on the surface after the end panel is welded on the pipe joint, which may easily cause deformation of the end panel and damage the flatness of the end panel; on the other hand On the one hand, it is very difficult to adjust the overall accuracy of the welded end panels, which can only be dismantled and re-welded to prolong the construction period of ship pipe joints

The invention relates to the technical field of steel shell immersed tube construction, and particularly discloses an end panel construction method. The method comprises the steps that pressing blocksare welded to one side face of an end panel; the end panel is arranged between a flange plate and a steel shell panel of a block body on a tube joint, and the other side face of the end panel faces the block body; clamping plates are arranged between the flange plate and the steel shell panel, and the clamping plates are provided with abutting blocks pointing to the side face of the end panel; the positions of the clamping plates, the flange plate and the steel shell panel are adjusted, and the end panel is driven by the abutting blocks to move relative to the block body so as to adjust the positions of the end panel, the flange plate and the steel shell panel; the clamping plates are detached when the end panel is parallel to the end face of the tube joint; and the end panel is fixedly connected with the tube joint. According to the end panel construction method, end panel deformation caused by subsequent welding of the pressing blocks can be avoided; and when the end panel is parallel to the end face of the tube joint, the end panel is fixedly connected, the adjusting difficulty of the end panel can be lowered, and the construction period of the ship tube joint is prevented frombeing prolonged.
Description
technical field [0001] The invention relates to the technical field of steel shell immersed tube construction, in particular to an end panel construction method. Background technique [0002] After the steel shell immersed pipe is sunk underwater, the joints of the pipe joints are sealed and waterproofed by extruding the GINA rubber waterstop. Among them, the GINA rubber waterstop is the first waterproof barrier and the most critical waterstop component of the immersed tube tunnel. The bottom of the GINA rubber waterstop is fixed on the end panel at the end of the pipe joint through bolts and pressure plates, and the end panel at the end of another adjacent pipe joint squeezes the "nose tip" of the GINA waterstop, so that the GINA rubber waterstop is squeezed on the The middle of the end panels of the two pipe joints achieves the purpose of sealing and waterproofing. [0003] Therefore, the flatness of the end panel used to contact the GINA rubber waterstop is very high, o...
