Highway Engineering Spherical Bearing Manufacturer 12000-Ton Swivel System Construction and Installation

In highway engineering, the use of a 12000-ton (approximately 117680 KN) swivel system with spherical bearings for bridge rotation construction is a project with high technical requirements and significant construction challenges. The following is a detailed introduction and key points regarding the construction and installation of spherical bearings for the 12000-ton swivel system:

I. System Overview

1. Swivel System Composition:

   • Spherical Bearing: The core component, consisting of upper and lower spherical hinges, sliding materials (such as PTFE plates), sealing devices, etc., used to bear the weight of the bridge and provide rotational functionality.
   • Traction System: Includes jacks, steel strands, reaction seats, etc., used to provide the power for rotation.
   • Support Structure: Includes temporary supports, rotation tracks, etc., used to ensure stability during the rotation process.
   • Monitoring System: Used to monitor the bridge's posture, rotation speed, and stress status in real-time during the rotation process.

2. Main Functions:

   • Bear the weight of the bridge and transfer it to the substructure.
   • Provide the rotational functionality required for bridge rotation construction, ensuring the bridge can be precisely rotated to the designed position.
   • Accommodate minor displacements and deformations during bridge construction.

3. Applicable Scenarios:

   • Rotation construction for highway bridges crossing complex terrains such as railways, roads, and rivers.
