[0002] Pipeline construction is an engineering project for building pipelines for transporting oil products, natural gas, and solid slurries. It includes pipeline route engineering, station and depot engineering, and pipeline auxiliary engineering. In a broad sense, pipeline engineering also includes the supply of equipment and materials. During the pipeline construction process, a safety protection net is required to prevent irrelevant personnel from approaching.

[0003] The prior art patent document with the publication number CN218406652U provides a construction safety protection net, including a first support column and a second support column. A protection net body is arranged inside the installation frame. A slot is opened on the outer surface of the fixed block away from the first support column. Springs are fixedly connected to the inner surfaces of the front and rear sides of the fixed block. Limiting blocks are fixedly connected to the outer surfaces of the two T-shaped rods facing each other. Limiting holes are opened on the outer surfaces of the front and rear sides of the insertion block. For this construction safety protection net, through the cooperation of the insertion block and the slot, and through the mutual cooperation of the spring, the limiting block, and the T-shaped rod, the limiting block is inserted into or separated from the limiting hole, solving the problem that the structure of the existing safety protection net is relatively simple, and when it is used in a large construction site, the protection net needs to be spliced, and the installation and splicing of the protection net are relatively cumbersome, time-consuming and laborious, reducing the work efficiency of the staff.

[0004] However, the existing safety protection net for pipeline construction cannot be stored, and it is not convenient to carry during transportation due to its large volume. Moreover, since pipeline construction is all temporary erection, and bolts and other structures are required for installation and fixation during erection, the safety protection net for pipeline construction is also not convenient for installation. For this reason, we propose a safety protection net for pipeline construction. Content of the Utility Model
