Construction Efficiency Improvement And Cost Optimization of Rotary Drilling Rig

In the field of construction, rotary drilling rig has become the main force of deep foundation construction with its advantages of efficient hole formation and strong adaptability. However, construction enterprises often face the difficulty of construction efficiency and cost control. How to improve the construction efficiency and reduce the cost of rotary drilling rig while ensuring the quality of the project? Here's the secret.

1. Suitable geological selection process: soft soil operation with large flow and high speed pressure drilling, clay layer continuous pressure drilling with low load; Pebble layer slow speed, smooth mudstone and hard gravel layer low speed drilling. Matching geological adjustment construction technology can greatly improve drilling efficiency.

2. Control equipment adjustment parameters: according to the engineering load and shock situation, reasonable adjustment of engine speed can not only improve construction efficiency, but also reduce fuel consumption. In addition, the functions of some advanced equipment such as a key rock can also reduce the intensity of manual operation and improve the speed of operation.

3. Strict selection of equipment to improve quality: the quality of big brand rotary drilling rig is more guaranteed, the failure rate is low, and the after-sales response is fast. Such as Zoomlion, Yutong and other brands of equipment, with advanced technology and stable performance, significantly improve the construction efficiency, help enterprises to reduce maintenance costs.

4. Polish the strong skills of the operation: the speed of the pile formation of the skilled machine is at least twice that of the novice. The operator should not only be familiar with the operation of the equipment, but also master the drilling skills of different geology, strictly abide by the construction specifications, and avoid the loss of equipment caused by improper operation.

5. Control mud loss: when drilling rotary drilling, the proportion of clay and mud is controlled between 1.4-1.6, and when cleaning holes, it is controlled between 1.20-1.30. Timely detection and adjustment of mud properties can prevent hole collapse, reduce material waste and reduce construction losses.

6. Reasonable planning and cost control: accurate calculation of equipment depreciation fees, leasing fees, fuel consumption and other costs before construction. According to the scale and duration of the project, select the appropriate equipment, optimize the personnel allocation, avoid idle resources, and reduce the overall construction cost.

By adapting geological technology, adjusting equipment parameters, strictly selecting construction equipment, improving machine skills, controlling mud quality and reasonably planning costs, the construction efficiency of rotary drilling rig can be effectively improved and the cost can be reduced. In the future, with the continuous progress of technology, the construction of rotary drilling rig will develop in a more efficient and economical direction.
