Horizontal directional drilling rig is a construction machine, it can lay a variety of underground utilities (pipelines, cables, etc.) without excavating the surface of the ground.
It is widely used in laying of flexible pipelines for water supply, electricity, telecommunications, natural gas, coal gas, oil, etc. It is suitable for sand, clay, and other conditions, but not suitable for high groundwater levels and pebble formations. It can be constructed in most non-hard rock areas .
The working environment temperature is -15℃~+45℃. Horizontal directional drilling technology is a new construction technology that combines the directional drilling technology of the petroleum industry with traditional pipeline construction methods. It has the characteristics of fast construction speed, low construction accuracy, and low cost. It is widely used in the laying of pipelines for water supply, coal gas, electricity, telecommunications, natural gas, oil, etc. Horizontal directional drilling equipment has also achieved rapid development in the past decade years and has become an emerging industry in developed countries. Its development trend is towards large-scale and miniaturization, adaptability to hard rock operations, self-contained anchoring system, automatic stacking and extraction of drill pipes, automatic lubrication of drill pipe connections, anti-electric shock system and other automated operation functions, ultra-deep guidance monitoring, wide application range, etc.
This type of equipment is generally suitable for steel pipes and PE pipes with a diameter of φ300~φ1200mm, with a maximum pipe laying length of up to 1500m, and is suitable for a variety of soil conditions from soft soil to hard rock, with broad application prospects.
