Description

Technical Field

[0001] The invention belongs to the technical field of civil engineering and mechanical automation, and in particular relates to an adaptive device and a casting method for a concrete well ring of a jacking pipe well. Background Art

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

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

[0004] 1. The traditional device has a fixed height and casting radius, which makes it difficult to adapt to the construction requirements of cylindrical formwork of different specifications. Frequent equipment adjustments or manual intervention are required, resulting in low efficiency.

[0005] 2. During the feeding process, the height cannot be adjusted or the pipeline is fixed, which can easily lead to concrete segregation or spillage, resulting in material waste and construction site pollution;

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

[0007] 4. It is highly dependent on manual adjustment of pouring position and monitoring of horizontality, which is labor-intensive and poses safety hazards.

[0008] To address the above issues, we propose an adaptive device and method for pouring concrete rings in pipe jacking shafts to achieve highly automated and adaptive adjustment functions, improve construction efficiency, reduce costs, and adapt to complex working conditions.
