Horizontal directional drilling rig
XZ13600 Horizontal Directional Drilling Rig PRODUCT FEATURE
Horizontal directional drilling rig (English abbreviation: HDD) is a kind of construction machinery that lays a variety of underground public facilities (pipelines, cables, etc.) under the condition of not excavating the surface, which is widely used in water supply, electricity, telecommunications, natural gas, gas, oil and other flexible pipeline laying facilities, it is suitable for sand, clay, and other ground conditions, not suitable for high groundwater levels and pebble formations, most of China's non-hard rock areas can be constructed.
Construction characteristics of horizontal directional drilling
1. The directional drilling crossing construction has the effect that it will not obstruct traffic, will not damage green spaces, vegetation and buildings, and will not affect the normal life and work order of residents.
2. Modern crossing equipment has high crossing accuracy, easy to adjust the laying direction and burial depth.
3. The buried depth of urban pipe networks generally reaches less than three meters, and when crossing rivers, they are generally buried 9-18 meters under the riverbed.
4. No water or underwater operations, no impact on river navigation, no damage to the dikes and riverbed structures on both sides of the river.
5. The speed of entering and exiting the site is fast, and the construction site can be flexibly adjusted.
6. Pre-reaming is to expand the hole back to the expected diameter according to 1.3~1.5 times the size of the pipe diameter step by step under the condition that the geological situation and underground pipeline detection or survey are clear.
XZ12000 Horizontal Directional Drilling Rig Performance Characteristics
1. Digital display system, rotational torque, push and pull force and other construction main parameters are directly displayed, overcoming the shortcomings of the pressure gauge used by traditional drilling rigs that need to be converted, and the operation is simple;
2. Power head rotation torque, push-pull force overload protection system, using electronic sensing, fast response, sensitive and high reliability; Rotational torque and push-pull force can be accurately preset; The power head spindle is floating, which reliably protects the drill pipe thread and improves the service life of the drill pipe;
3. Four-power system, using Cummins EFI engine, any engine can complete all the actions of the whole vehicle when started, which can realize multi-engine combination technology, combined with multi-speed stepless speed regulation technology, adapt to a wide range of addresses, and low construction costs;
4. Two groups of eight cylinders clamp the vise, the drill pipe clamping is reliable, and the shackle torque is large; The vice floats throughout the whole process, passing a diameter of 400mm, which is convenient for the casing method construction process.
