Recently，XCMG Basic R & DSuper large tonnageElectricityMachine direct driveXZE8200 Horizontal Directional Drilling MachineAppeared at Daoyanghe Construction Site of East Main Line of Shandong Pipeline Network，AndXZ5060 Joint Construction Helps Shandong Main Pipeline Network Project，Double-machine synchronous reaming operation，And that ream efficiency is improved40%Above。
The pipeline for this construction isDN1200 steel pipe，Crossing length: 835m。The strata it passes through are mainly completely weathered granite gneiss.、Highly weathered granitic gneiss、Moderately weathered granitic gneiss。There is an area where the soft and hard strata intersect.，A portion of the traversing formation rock has a hardness of up to80MPa，Part of the formation is loose.、Pore-forming property is poor，It will make the mud difficult to preserve.，Therefore, it is very challenging to carry out Trenchless crossing construction in this stratum.。
Other than that，The elevation difference between the entry and exit points is about 20m.，The large elevation difference also makes it extremely difficult for the mud to remain in the hole that has been drilled，Increasing the difficulty of construction。The project is also known as the difficult part of the whole East Trunk Line project.“Tough bones”。
The construction stratum of the project is complex.，Large torque required in construction，The construction party adopts XCMGXZ5060 Horizontal Directional Drilling Rig combined with XCMGXZE8200Double-machine synchronous reaming construction，Double the reaming speed in hard formation。
In the construction process of synchronous reaming of two machines，Two rigsOne is responsible for pushing in Hedong.、One is responsible for pulling on the west bank of the river.，Output torque to form resultant force，Reduces torque losses due to low bore friction，Lifting in complex geology、Long distance、Hole enlargement speed of big bore engineering construction，And that success rate of the engineer construction is greatly guaranteed.。
XZE8200 horizontal directional drilling rig is the focus of XCMG's foundation. At present, the cost of Trenchless construction is high.、The super-large tonnage motor direct-drive horizontal directional drilling rig is developed for the pain points such as construction disturbance to the people.。Although it is an electric driving force，XugongXZE8200 follows XCMG large-tonnage drilling rig with fast push-pull speed、Traditional advantage of large pullback force，Particularly suitable for long distances、High difficulty、Construction of crossing conditions in complex terrain。
XCMG's large-tonnage electric drive complete scheme is also officially launched with a new generation of electric drive drilling rigs.，With the newXMP3000EElectrically driven mud pump，The construction state can be monitored.，The mud pump can realize automatic start-stop or one-key idling.，Greatly save mud consumption。And can carry out intelligent remote control.，Start and stop control of mud pump、Flow control、State detection、Fault diagnosis。
XugongXZEThe 8200 horizontal directional drilling rig is directly driven by the motor to rotate, push and pull.，It has achieved many advantages that traditional drilling rigs can not match.。The most important one is the calculation of this construction.，Compare with that traditional directional drilling machine，And that fuel oil is save、Engine oil、Coolant and other engine maintenance and service costs，Pecially when an external power supply is adopted,The comprehensive use cost can be reduced50%Above。
