Multifunctional Horizontal Directional Drilling Equipment For Water Wells

Horizontal directional drilling rig is a construction machine for laying a variety of underground utilities (pipes, cables, etc.) without digging the ground surface. It is widely used in water supply, electricity, telecommunications, natural gas, gas, oil and other pipelines. During construction, it is suitable for sand, clay, pebbles and other land conditions, and most of the non-hard rock areas in China can be constructed. The working environment temperature is -15 ° C ~ +45 ° C. Horizontal directional drilling technology is a new construction technology that combines the directional drilling technology of the petroleum industry with the traditional pipeline construction method. It has the advantages of fast construction speed, high construction precision and low cost, and is widely used in water supply. Pipeline construction work for gas, electricity, telecommunications, natural gas, petroleum, etc. Horizontal directional drilling equipment has also achieved rapid development in more than a decade and has become an emerging industry in developed countries. At present, its development trend is toward large-scale and miniaturization, adaptation to hard rock operations, self-contained anchoring systems, automatic stacking and extraction of drill pipes, automatic lubrication of drill pipe connections, anti-shock system and other automated operation functions, ultra-depth guidance monitoring, The application of a wide range of features and other characteristics. This kind of equipment is generally suitable for steel pipes and PE pipes with diameter φ300~φ1200mm. The maximum pipe length can reach 1500m. It is suitable for various soil conditions from soft soil to hard rock, and has broad application prospects.

Horizontal directional drilling construction features:

2.1 Directional drilling through construction will not hinder traffic, will not damage green spaces, vegetation, will not affect the normal life and work order of shops, hospitals, schools and residents, and solve the interference of traditional excavation construction on residents' lives, on traffic, The environment, the destruction and adverse effects of the surrounding building foundation.
2.2 The modern crossing equipment has high crossing precision, easy to adjust the laying direction and depth of the pipeline, and the pipeline has a long arc-laying distance, which can fully meet the design requirements, and can make the pipeline bypass the underground obstacles.
2.3 The buried depth of urban pipe network generally reaches less than three meters. When crossing the river, it is generally buried 9-10 meters below the riverbed. Therefore, it is traversed by a horizontal directional drilling machine, which has no impact on the surrounding environment, does not damage the landform and environment, and adapts to environmental protection. Item requirements.
2.4 When using horizontal directional drilling machine to cross the construction, there is no water or underwater operation, no impact on river navigation, no damage to the dam and riverbed structure on both sides of the river, construction is not subject to seasonal restrictions, with short construction period and low success rate. Features.
2.5 Compared with other construction methods, the speed of entering and leaving the site is fast, and the construction site can be flexibly adjusted. Especially in urban construction, it can fully demonstrate its superiority, and the construction area is less, the construction cost is low, and the construction speed is fast.
2.6 When a large river passes through, the pipeline is buried 9 to 18 meters below the stratum, and there are few oxygen and other corrosive substances inside the stratum, so it plays the role of natural anti-corrosion and heat preservation, which can ensure the pipeline running time is longer.
