The construction techniques and operational methods for steel supports during actual installation involve multiple critical steps to ensure safety and effectiveness. Here are the detailed construction techniques and operational methods:
Preparation underway：
Clear the construction site of obstructions to ensure a safe environment for installation.
Inspect the quality and structural integrity of steel supports to ensure they meet design specifications and can be used normally.
Measurement and Positioning：
Based on the design drawings and construction specifications, the installation positions of the steel supports have been determined.
Utilizing equipment such as theodolites, measurements and positioning are conducted to ensure precise support placement.
Basic processing：
According to the design specifications, foundational treatments such as excavation of pits and pre-b埋 bolts are conducted at the installation location.
Ensure a solid and level foundation to support the stability of the steel structure.
Steel support assembly：
Due to the limited space on the construction site, steel supports are usually pre-assembled outside the foundation pit.
After pre-assembly is completed, the steel supports are sectioned and hoisted into the foundation pit before being assembled on-site.
Utilizing high-tensile bolts to connect the supporting steel pipes ensures symmetrical and secure connections, preventing eccentric loading.
Installation and Adjustment：
The assembled steel supports are installed at the designated location.
Utilizing equipment such as theodolites for adjusting vertical and horizontal alignments to ensure the stability and non-tilt of the supporting structure.
Welding and Fastening：
Welding between the support and foundation, as needed, to enhance connection strength.
Secure the steel support firmly in place using bolts or other fastening methods.
Inspection and Acceptance：
Upon completion of the installation, inspections were conducted on the steel supports, including the quality of welds and the tightness of connections.
Steel supports meeting requirements have been inspected and are ready for subsequent construction work.
Throughout the installation process, the following points should be noted:
Ensure that the construction site roads are kept clear for the installation and transportation of steel supports.
Construction workers must wear hard hats, protective eyewear, and other personal protective equipment to ensure safety on the job site.
Adhering to construction regulations and standards to ensure the construction quality meets design requirements.
By adhering to the aforementioned construction techniques and operational methods, the safety and effectiveness of steel supports during actual installation can be ensured, providing robust support for the stability of the engineering structure.
