Horizontal Directional Drilling technique enables quick and efficient solutions

Looking for a quick and effective solution to build pipelines without causing any disturbance to the surrounding environment? The horizontal directional drilling (HDD) technique is your answer. HDD is an ecological and modern technology that allows underground infrastructure to be installed without the need for large trenches or disruption to the surrounding landscape.

The horizontal directional drilling technique is a cost-effective solution, especially for soft soils, as it can drill to depths of up to 1,500 meters. However, the most cost-effective drilling is to a depth of 500 meters or less. This makes it ideal for a variety of projects, whether laying pipes under highways, rivers, or residential areas.

One of the main advantages of HDDs is their ability to minimize environmental damage. Traditional excavation methods lead to the destruction of natural habitats and vegetation, as well as traffic congestion and public inconvenience. With HDD, the surface remains largely undisturbed, preserving the natural beauty of the landscape.

In addition to being environmentally friendly, HDDs are also an economical solution. Overall project costs were reduced by minimizing the need for extensive excavation and restoration. This, coupled with the ability to drill holes over long distances, makes HDD an attractive option for projects of all sizes.

Developments in horizontal directional drilling techniques have made it a superior choice for many underground infrastructure projects. Able to cope with challenging terrain and varying soil conditions, HDDs provide a versatile, efficient solution favored for its ecological benefits.

When considering pipeline installation, especially in environmentally sensitive areas, horizontal directional drilling is the best choice. Its ability to provide fast, efficient, and environmentally friendly solutions makes it the first choice for modern infrastructure projects. With HDDs, you can rest easy knowing your projects will be completed with minimal disruption and maximum efficiency.

Mud Treatment in Directional Drilling Construction

Mud Treatment in Directional Drilling Construction

Horizontal directional drilling machines operate using a cantilevered method, where the drill bit is laterally excavated to the desired drilling position through a guidance system. As the drill bit rotates, it is hydraulically advanced using a drill stem. This method enables the drill bit to progress in the required direction, continuously expanding the diameter of the borehole to the desired size.
Applications of horizontal directional drilling machines include:

Geological exploration
Petroleum extraction
Foundation engineering and metro tunnel construction

Treatment of mud generated during directional drilling construction:
Mud is a necessary material in the process of horizontal directional drilling, used to carry cuttings back to the surface, cool the drill bit, and provide lubrication. Mud is a mixture of bentonite and water in certain proportions. Xi’an KOSUN’s mud recovery system is designed to remove sand and silt from the returned mud for the purpose of reuse. Reusing the mud can reduce the amount of residual mud that needs to be processed. The primary material filtered out by the recovery system is drill cuttings generated from cutting through rocks, consisting mainly of sandstone, mudstone, siltstone, and shale fragments. These are classified as category II solid industrial waste, with no significant environmental hazards. After completion of the project, the remaining drill cuttings are transported by specialized vehicles to designated locations specified by the environmental protection department and processed according to their specific requirements.
