Ii. Adaptability of Hydraulic Anchor Drill Trucks under complex geological Conditions
In complex geological conditions, common challenges include significant differences in stratum hardness, abundant groundwater, weak layers, and unstable rock strata. The adaptability of the hydraulic anchor drill truck is reflected in the following aspects:
1. Cope with the hardness of different strata
In mining and tunnel construction, rock layers of different hardness are often encountered, such as sandstone, shale, granite, etc. The hardness of different rock strata directly affects the drilling speed and efficiency of the drilling vehicle. The hydraulic system through which the hydraulic anchor drill truck passes can automatically adjust the pressure and rotational speed during drilling according to the hardness of the rock layer.
In soft rock or sedimentary rock, the hydraulic anchor drill truck can ensure rapid drilling by adjusting the drilling rate and adapting the soft rock drill bit.
For hard rocks such as granite and limestone, the hydraulic system can provide greater power output and, in combination with high-hardness drill bits, ensure drilling efficiency and hole quality.
This automatic adjustment capability enables the hydraulic anchor drill truck to quickly adapt to rock layers of different hardness and maintain high operational efficiency.
2. Adapt to complex faults and unstable strata
Faults, folds and other phenomena in geological structures often lead to the instability of underground rock strata. When encountering these complex geological conditions, traditional drilling vehicles may encounter operational difficulties due to the difficulty in controlling the drilling speed or the damage of the drill bit. The hydraulic anchor drill truck, through its powerful hydraulic system, can adjust the pressure and speed required during the drilling process, especially demonstrating strong adaptability in geological environments such as fault zones and weak rock layers.
Stability improvement: The hydraulic anchor drill truck can enhance its stability in faults and weak layers by adjusting the operating system, avoiding equipment damage or stuck drill caused by unstable strata.
Flexibility in drill bit selection: The drilling vehicle is equipped with various types of drill bits, such as three-cone drill bits and hob drill bits, which can be flexibly selected according to geological conditions to ensure the durability and adaptability of the drill bit when encountering hard rock and faults.
3. Dealing with groundwater and moist soft layers
In areas rich in groundwater, drilling operations often encounter challenges such as soil erosion, borehole collapse and weak strata. The hydraulic anchor bolt drilling vehicle can effectively address these issues. Its hydraulic system and drilling control technology make the operation process safer.
Preventing borehole collapse: In areas with abundant groundwater, the drilling vehicle can be used in conjunction with the water injection system for continuous flushing to ensure that the borehole is not blocked by sediment and prevent the problem of borehole wall collapse when operating in weak or wet soft layers.
Waterproof control system: Some advanced hydraulic anchor drill trucks are equipped with a waterproof control system, which can perform stable operations in wet and soft layers or areas with abundant groundwater, ensuring the support effect of the borehole.
4. Adapt quickly to complex environments
In tunnel construction and mining, complex geological conditions and narrow working Spaces often pose significant challenges to the operation of equipment. Hydraulic anchor drill trucks are usually compactly designed and highly flexible, enabling them to perform drilling operations in confined Spaces. Moreover, its hydraulic drive system not only has strong power but also can control actions, ensuring the operation of the equipment in complex environments.
Adaptability to small Spaces: The hydraulic anchor drill truck can complete operations in narrow tunnels, mines or complex construction sites through flexible layout and adjustable drill arm design.
High-precision operation: The automatic control system of the hydraulic anchor bolt drilling vehicle can adjust the drilling Angle and depth according to the on-site conditions, ensuring that each hole meets the design requirements and improving the construction accuracy.
