Construction Requirements For Steel Support Pressurization

After the steel support is installed, the connection condition of each node shall be checked in time. The pre pressure can be applied only after it is confirmed to meet the requirements. The pre pressure shall be applied synchronously and symmetrically at both ends of the support; The pre pressure shall be applied by stages and repeated. When it is added to the design value, the condition of each connection point shall be checked again. If necessary, the nodes shall be reinforced and locked after the rated pressure is stable.
