Grouting works drilling rig is a specialized piece of equipment used in geological reinforcement, waterproofing, and foundation treatment projects. This type of machine primarily functions to drill grouting holes and provide access for subsequent grouting operations. Its working principle involves using either rotary drilling or percussive drilling methods to create boreholes of specific diameter and depth within soil or rock layers, followed by injecting cement slurry, chemical slurries, or other filling materials into underground structures or soil through these drilled holes. The ultimate goals are to consolidate soil, enhance the bearing capacity of foundations, prevent leakage, among others.
A typical Grouting works drilling rig generally comprises several main components:
1. Drilling Frame System: Supports the overall rig structure and operating platform.
2. Drilling Mechanism: Includes a power head, drill rods, and drill bits that execute the drilling task.
3. Grouting System: Consists of grouting pumps, pipelines, and injection ports, responsible for preparing and delivering the grout mixture.
4. Control System: Manages the operation of the drilling rig, allowing for the setting and monitoring of parameters such as drilling speed, grouting pressure, and flow rate.
5. Transportation Devices: Facilitate movement and repositioning of the drilling rig.
Grouting drilling rigs are widely employed in tunnel engineering, mining, slope management, foundation strengthening, reservoir dam waterproofing, building rectification, and various other fields.
