Embodiment Construction

[0030] see figure 1 (The direction of the arrow is the pushing direction of the reinforcement cage), a method for installation and adjustment of the steel shell at the pipe joint end of the present invention, the installation and adjustment method includes the following steps:

[0031] 1. See figure 2 As shown, the steel shell at the bottom plate end, the steel shell at the web end 2 and the steel shell at the top plate end are made on the temporary mold; the bottom plate steel bar binding process of the pipe joint is carried out at the bottom plate steel bar binding platform; the bottom plate steel bar of the pipe joint is bound After the process is completed, install the bottom plate end steel shells at the front and rear ends of the bottom plate reinforcement;

[0032] 2. After the steel shell at the end of the bottom plate is installed, the steel bars on the bottom plate are sequentially pushed to the web binding pedestal and the top plate tying pedestal through the stee...

Abstract

The invention relates to an installing and position adjusting method for a pipe joint end steel shell, in particular to an installing and positioning adjusting method for performing planarity precise adjusting to install the pipe joint end steel shell in a high-precision mode through precise adjusting components. The installing and position adjusting method includes the following steps that after a bottom plate steel bar binding process of a pipe joint is finished, a bottom plate end steel shell is correspondingly installed; after the bottom plate end steel shell is installed, a web steel bar binding process and a top plate steel bar binding process of the pipe joint are sequentially performed; after pipe joint steel bar cage binding is finished, a web end steel shell and a top plate end steel shell are correspondingly installed on web steel bars and top plate steel bars; a steel bar cage is sent to a pouring platform, and the bottom plate end steel shell, the web end steel shell and the top plate end steel shell are connected to form the pipe joint end steel shell; an end die with the precise adjusting components is correspondingly installed on the pipe joint end steel shell, and planarity checking is performed on the pipe joint end steel shell through the precise adjusting components; a concrete pouring process is performed on the pipe joint end steel shell.

Description

technical field [0001] The invention relates to a method for installation and adjustment of steel shells at pipe joint ends, in particular to an installation and adjustment method for finely adjusting the flatness of steel shells at pipe joint ends through fine adjustment members to achieve high-precision installation of steel shells at pipe joint ends . Background technique [0002] In recent years, with the development of factory prefabrication of large-scale immersed tubes, the size of prefabricated immersed tubes tends to be larger according to functional requirements, and the waterproof embedded parts of pipe joints - end steel shells tend to be overweight, oversized, and require higher precision. development in a high direction. In the prefabrication of pipe joints, the installation accuracy of the steel shell at the pipe joint end is very high (flatness ≤ 5mm). After the embedded parts are installed, the overall installation accuracy of the components usually cannot ...
