AI Technical Summary
In the existing technology, traditional cross-pipe protection devices cannot effectively protect pipelines and cause disturbance to the safety of trenches and pits. They also have poor versatility and cannot be adapted to pipelines of different types and elevations.
Supporting and load-bearing steel sections are used to cross the trench, and the pipes are connected by telescopic rods and clamp-type protective sleeves. The load-bearing steel sections are not directly supported on the retaining piles. Flexible pads and adjustable sleeve structures are used to increase the contact area and load-bearing capacity, thus avoiding damage.
It improves the safety of protection when crossing pipelines, avoids disturbance to trenches and pits, enhances the versatility of the device, adapts to different elevations and pipe diameters, and reduces the risk of damage to pipelines.
