Description

Technical Field

[0001] This invention belongs to the field of civil engineering and mechanical automation technology, and particularly relates to an adaptive device and method for pouring concrete well rings for pipe jacking wells. Background Technology

[0002] In the field of civil engineering, the casting of cylindrical concrete structures (such as bridge piers and building columns) usually relies on steel formwork as molding molds.

[0003] Traditional casting equipment mostly uses fixed material conveying pipelines and manual operation, which has the following significant problems:

[0004] 1. Traditional equipment has a fixed height and pouring radius, which makes it difficult to adapt to the construction needs of cylindrical formwork of different specifications. It requires frequent equipment adjustments or manual intervention, resulting in low efficiency.

[0005] 2. During the material conveying process, if the height is not adjustable or the pipeline is fixed, it is easy to cause concrete segregation or spillage, resulting in material waste and pollution at the construction site;

[0006] 3. When constructing in complex terrain (such as slopes or soft foundations), traditional self-leveling support platforms are difficult to level quickly, which can easily cause equipment to overturn or the pouring position to shift, affecting construction accuracy.

[0007] 4. It relies heavily on manual adjustment of the pouring position and monitoring of the levelness, which is labor-intensive and poses safety hazards.

[0008] To address the aforementioned issues, we propose an adaptive device and method for pouring concrete well rings in pipe jacking wells, which enables highly automated and adaptive adjustment functions, improves construction efficiency, reduces costs, and adapts to complex working conditions.
