Concrete Drilling and Coring Machine

The Concrete Drilling and Coring Machine is a versatile tool primarily used for two main functions: horizontal drilling and coring. It is widely used in various industries, including transportation engineering, construction, and materials testing. This machine is essential for tasks like installing road studs, conducting coring tests for material evaluation, and foundation drilling for integrated houses.

Operational Information:

Preparations Before Use:

1. Fuel: Add 93# unleaded gasoline (for gasoline-powered models) and lubricating oil according to the dipstick scale.
2. Lubrication: Add lubricating oil to the column and ensure the feed and rotation mechanisms work smoothly.
3. Water Source: Prepare an adequate water supply.
4. Inspection: Check all screws and parts for looseness.

Installation and Setup:

• Align the drill bit with the hole and raise the three walking wheels, allowing the base to rest on the ground.
• For small holes or low concrete strength, secure the drilling rig using weight (such as iron or concrete blocks) or expansion bolts.

Drilling Process:

1. Initial Setup: Start the gasoline engine, connect the water inlet pipe to a bucket, and use the air pump to fill the pump with water.
2. Drilling Tips: Always ensure water is supplied before drilling to prevent overheating of the drill bit. Feed water slowly and apply light pressure initially.
3. Normal Drilling: As the hole deepens, increase the feeding pressure moderately and uniformly. Ensure the drill bit operates smoothly.
4. End of Hole: Upon reaching the desired depth, stop the machine and turn off the water. If drilling deep holes, allow some water to flush out rock powder to prevent blockage.

Applications:

• Road Drilling: For road studs, piles, and bridge construction.
• Material Testing: Used in detection centers for road coring to assess material quality.
• Foundation Drilling: For integrated housing projects and other foundational needs.

This machine is perfect for those needing precise and reliable drilling and coring for various construction and testing applications.
