沉管全断面浇筑的配套干坞系统及布置方法.

In order to realize the full-section pouring construction of the immersed tubeby dry dock method, the compatibility of the dry dock system suitable for full -section pouring was studied and designed. The dry dock system is equipped with a specific floor structure to ensure that the prefabrication of the immersed tube does not cause excessive settlement. The supporting formwork support system makes the formwork stably stressed and deformation controllable during the pouring construction process. A supporting complete transportation system is provided to ensure smooth traffic of construction equipment. The drainage system combining the bottom and top of the dock is set up to ensure that the accumulated water in the dock door can be discharged in time and quickly, which guarantees a good dry construction environment for the prefabrication of immersed tubes. The supporting tower cranes and gantry cranes are connected with each other to achieve full coverage of the construction scope of hoisting in the dock. The supporting the movable steel dock door to realize the repeated use of the dry dock. The dry dock system has been applied to the Chebei Road -Xinjiaodong Road Tunnel Project with good application effects. [ABSTRACT FROM AUTHOR]
