Horizontal directional drilling rig
XZ1600 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.
XZ1600 Horizontal Directional Drilling Rig Performance Characteristics
1. Digital instrument, automatically display the actual torque, push and pull force and other main construction parameters in construction, simple operation; Electronic sensing technology is responsive, can timely feedback instantaneous overload, reliable protection of drilling rigs;
2. PE pipeline elastic balance release technology, effectively prevent equipment damage caused by the reaction force of the dragging pipeline, and improve the reliability of equipment construction;
3. Overload protection technology, drilling rig rotation torque, push and pull force and vice clamping force can be adjusted and adopt digital pressure regulation technology, easy and simple adjustment, can be accurately preset.
