Background technique

Civil engineering is a general term for the science and technology of building various engineering facilities. It not only refers to the applied materials, equipment and technical activities such as survey, design, construction, maintenance and repair, but also refers to the object of engineering construction, that is, the construction on the ground or underground, on land or in water, directly or indirectly for human life. Various engineering facilities for production, military and scientific research services, such as houses, roads, railways, transportation pipelines, tunnels, bridges, canals, dams, ports, power stations, airports, offshore platforms, water supply and drainage, and protection engineering. At the construction site of civil engineering, it is often necessary to use some devices to facilitate the transportation of pipelines. However, these existing transportation devices generally have some defects: the terrain of the construction site is complex, large machinery is difficult to enter and exit, and manual transportation is labor-intensive; the shockproof effect is poor. Damage to the pipeline; Another one is that the pipes used in civil engineering are round and have different sizes and diameters, which has higher requirements for pipeline transportation devices.
