“Minimally Invasive Operation”For Laying Urban Pipe Network -- Brief Introduction of Horizontal Directional Drilling Rig

“Zipper Road”

We often find that in the city where we live, roads are often dug up. Whether newly built or used for a period of time, we always feel that the roads around our residence have never been intact. We dig and repair them every day, it is not convenient to travel, but also causes environmental pollution, the phenomenon of digging out a part of the road is also known as the “Zipper Road”.

The main reason for this type of Zipper is not only that the road is damaged, but also that the road was not well planned when it was built, and with the rapid development of the city, the existing underground pipelines can not keep up with the demand of the city, in addition, some new pipelines also need to cross the road.

A few days ago, I saw a news report that a certain place has stipulated that the newly-built urban roads should not be dug up for 5 years after they are delivered for use. This will effectively put an end to the phenomenon that urban roads are often dug up. It will also avoid the economic losses caused by the repeated occurrence of “Zipper Road”.

But at the same time, it puts forward higher requests to the construction of the underground pipe network of the city road.

Horizontal Directional Drilling Rig

Do you often see a machine at work in the city's green belt, or on the sidewalk, inserting a rotating iron pipe into the ground to make a hole, and not far away inserting cables and pipes into the hole made by the machine, this machine is the horizontal directional drilling machine.

A horizontal Directional Drilling Machine is the mechanical equipment for laying underground pipelines without the need to excavate the ground. It can avoid obstacles successfully within a certain radius of the ground. It can be operated in underground strata such as clay, sand, and so on. It is widely used in electric power, flexible pipeline laying in the fields of communications, oil, and natural gas.

Unlike road closures and major road repairs, horizontal directional drilling rigs can be built on the side of the road without affecting traffic or people’s normal travel, as we often see.

Through the advanced HDD drilling equipment calculation and positioning, can let the whole drill through the process of bypassing obstacles to reach the intended location, to ensure the construction accuracy.

Compared with the traditional construction method, horizontal directional drilling has many advantages such as high construction efficiency, low cost, no environmental impact and so on.
