Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction tools and equipment, specifically to an end protection device for steel pipe construction. Background Technology
[0002] In recent years, with rapid economic development and accelerated urban construction, more and more deep foundation pit projects have emerged. The increasing area of foundation pits has led to numerous environmental problems with traditional internal support systems, such as the need for large quantities of steel reinforcement and concrete; and the need for extensive demolition work after construction, generating noise and dust pollution. Consequently, inclined support technology, similar to sloping bracing, has been widely applied. As a special form of support, inclined support technology has the following advantages: First, compared to unsupported cantilever structures, it can better control deformation and is more commonly used in complex environmental conditions. Second, compared to slab-type retaining structures with internal support systems, it allows for direct construction of inclined supports on the original ground surface, reducing construction time, reducing the material consumption of traditional reinforced concrete and steel internal supports, increasing the unsupported working surface within the foundation pit, and facilitating construction.
[0003] During the process of inserting inclined support steel pipes, the steel pipe opening is often directly gripped by a robotic arm, which can easily cause the following problems: (1) It can easily cause stress concentration at the gripping part, causing the steel pipe opening to bend, deform, or break, affecting the later connection with the crown beam. If the damage is too large, it may even need to be cut off, resulting in a waste of resources; (2) The steel pipe wall is arc-shaped, and the robotic arm may not grip it firmly, which may cause twisting or slippage, creating a safety hazard. Therefore, we have improved the above-mentioned existing technology based on the actual usage. Utility Model Content
