Description

Permanent casings are the type of segmental casing liners which are used to stabilize the borehole in the construction of drilled shaft. As its name implies, permanent casings need to retain in the hole and to be a permanent part of the pile.

Permanent steel casing can be installed by using an impact hammer, rotary drilling rig or using the oscillator/ rotator method. As permanent steel casing has no male/female casing joint on the end of the steel tube, it’s often joined by welding.

Kimdrill manufacture the permanent casing with high quality steel Q355B and it’s available in required wall thickness and length to meet client’s requirements. For the permanent casing which’s applied to rotary drilling rig, we can process the permanent casings with slot on the end of the tube to connect with casing twister.

FAQ

1. What is a double wall casing tube?

A double wall casing tube is a construction tool used in drilling, consisting of two concentric tubes. It's employed to provide structural support and stability in boreholes, especially in unstable ground conditions.

2. How is the double wall casing tube structured?

It comprises an outer tube that offers structural support and an inner tube for various drilling operations, including the insertion of reinforcement materials.

3. Why are double wall casing tubes used in drilling?

They are used to prevent the collapse of borehole walls in unstable soil conditions, ensuring the integrity of the borehole and the safety of the drilling operation.

4. In what types of projects are double wall casing tubes commonly used?

These tubes are commonly used in deep foundation drilling, such as for building foundations and bridges, where borehole stability is crucial.

5. What role does the space between the inner and outer tubes play?

This space is often used for the circulation of drilling fluids, aiding in stabilising the borehole, cooling and lubricating the drilling tools, and removing drill cuttings.

6. What materials are used to make double wall casing tubes?

They are typically made from high-strength steel, capable of withstanding the stresses of drilling and providing long-term stability.

7. Are double wall casing tubes permanently installed in the ground?

They can be either permanent, left in the ground as part of the foundation structure, or temporary, removed after the drilling is completed, depending on the project requirements.

8. Can the dimensions of double wall casing tubes be customised?

Yes, they are available in various diameters and lengths and can be customised to suit specific drilling requirements, such as the depth and diameter of the borehole and the ground conditions.

9. How are double wall casing tubes installed?

They are typically installed using a rotary drilling rig, designed to handle the specific dimensions and weight of the casing tubes.

10. What are the key benefits of using double wall casing tubes in construction?

The main benefits include enhanced stability in unstable soil conditions, improved safety during drilling operations, and the ability to maintain the integrity of deep boreholes during construction projects.
