Description

Technical Field

[0001] The utility model belongs to the technical field of stainless steel lined pipes, and in particular relates to a fixing frame used on the stainless steel lined pipes. Background Art

[0002] In the process of underground space construction, due to the crisscross distribution of urban underground pipelines, it is necessary to relocate or protect the existing pipelines before construction. For the rainwater and sewage pipes that need to be protected, the use of stainless steel lining welding + cement grouting technology is currently being vigorously promoted. Adding lining to reinforce the pipeline can improve the rigidity and strength of the pipeline. Taking the DN3500 stainless steel pipe segment size as an example, the weight of a single piece is 1m×1.5m×10mm, weighing 120kg, and 7 stainless steel plates are required to splice the entire ring;

[0003] The key difficulty in splicing the upper pipe segments of DN3500 stainless steel lined pipes is to work at the 10 o'clock to 2 o'clock position of the pipeline. Due to the heavy weight of the lining pipe segments themselves, it takes 6 people to move them on flat ground. Therefore, it is impossible to fix and splice them at the upper end of the pipeline by manpower alone. In addition, the construction at the 10 o'clock to 2 o'clock position of the pipeline is a high-altitude operation. The current conventional practice is to install hooks on both sides of the upper part of the pipeline, and place a set of manual hoists on the two hooks respectively, and use manpower to pull the lining steel plate to the pipeline installation position. This approach has two disadvantages: ① When placing the hook, the original pipeline is drilled, which destroys the integrity of the original pipeline structure, and after the stainless steel plate is installed, the hook hole cannot be further repaired; ② The connection between the hook and the pipeline often relies on the upward pulling force of the rod. If the force transmission rod is not tightly connected to the pipeline and the pipeline structure is loose over the years, the force transmission rod cannot guarantee the upward pulling force when the stainless steel plate is hoisted, and the stainless steel plate falls, causing unpredictable safety hazards. For this reason, the utility model proposes a fixing frame used on the stainless steel liner pipe. Utility Model Content
