Construction conditions and characteristics of horizontal directional drilling rig
Horizontal directional drilling rig is a construction machine that lays a variety of underground utilities (pipes, cables, etc.) without digging the ground surface. It is widely used in water supply, power, telecommunications, natural gas, gas, oil and other pipeline It is suitable for sand, clay, pebbles and other ground conditions during laying construction, and it can be constructed in most non-hard rock areas in China. 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 advantages of fast construction speed, high construction accuracy, low cost, etc. It is widely used in water supply, Construction of pipelines for coal gas, electricity, telecommunications, natural gas, oil, etc. Horizontal directional drilling equipment has also achieved rapid development in more than ten years, and has become an emerging industry in developed countries back to China. At present, its development trend is toward large-scale and miniaturization, adaptation to hard rock operations, self-provided anchoring system, automatic stacking and extraction of drill rods, automatic lubrication of drill rod connections, anti-electric shock system and other automatic operation functions, ultra-depth guidance monitoring, Features such as wide application range. This kind of equipment is generally suitable for steel pipes and PE pipes with a diameter of φ300 ~ φ1200mm. The maximum pipe laying length can reach 1500m. It is suitable for various soil conditions from soft soil to hard rock, and has a broad application prospect.
