In scenarios such as old city renovation and interior refurbishment of factories, construction space is often restricted by buildings, fences, etc. Through special design and technical adjustment, rotary drilling RIGS can complete efficient hole-forming operations in narrow areas.

1. Select miniaturized models: For confined Spaces, there are dedicated small rotary drilling RIGS. The body width can be controlled within 2.5 meters, and the turning radius is smaller. Its folding drill mast can reduce the height during transportation and operation, adapting to low-rise environments.


2. Flexible movement of the crawler chassis: The crawler walking structure has low space requirements and can slowly turn in narrow passages. In combination with the track extension function, the width of the machine body can be adjusted to adapt to different space dimensions.


3. Precise operation of the short-arm drill mast: After shortening the length of the drill mast, the swing range of the drilling rig during rotation is reduced, avoiding contact with surrounding obstacles. Meanwhile, the short arm design makes the lifting and lowering of the bucket more controllable, making it suitable for small-scale operations.


4. Partial site pretreatment: Clear the surrounding debris before operation. If necessary, remove some temporary facilities to expand the space. For areas with insufficient ground load-bearing capacity, steel plates can be laid to distribute the weight of the machine body and ensure the safety of movement.


5. Visualization-assisted positioning: The body is equipped with a 360-degree camera to display real-time images of the surrounding environment. The operator observes the distance of obstacles through the screen and precisely controls the movement range of the drilling rig in combination with the laser positioning instrument.


6. Segmented hole-making process: In Spaces with limited height, the method of "short-section drilling and multiple soil extraction" is adopted. Each drilling depth should be controlled within the allowable range of the drill mast, and the hole should be completed gradually to avoid collisions caused by excessively high drill masts.


Conclusion: Through model selection, structural adjustment and process optimization, rotary drilling RIGS can meet the operation requirements in narrow Spaces. Its flexible mobility and precise operation control enable it to maintain construction efficiency even in restricted environments, providing a reliable foundation construction solution for projects such as urban renewal.
