Pipe pushers VS Pipe jacking machines

Both pipe pushers and pipe jacking machines play an important role in pipeline construction, but they have obvious differences in working principles, scope of application, usage scenarios and usage effects. The following is a detailed comparison of the two:

1. Working principle
Pipe pushers: Use high-pressure compressed air or other power sources to convert the energy of air or other media into thrust to push the pipeline forward. This thrust is usually achieved through the mechanical structure or hydraulic system inside the pipe pusher.

Pipe jacking machine: It mainly controls the advancement of the pipe jacking machine head through the hydraulic system, while carrying out earth excavation, earth transportation, support and other processes. It uses the thrust generated by the hydraulic cylinder or hydraulic jack to push the pipeline into the soil.

2. Scope of application
Pipe pushers: Usually suitable for soft soil formations, such as sand, soil, etc. In these formations, pipe pushers can use a small thrust to push the pipeline forward.

Pipe jacking machine: It is more suitable for hard soil formations, such as clay, rock, etc. The pipe jacking machine can generate a large thrust to overcome the resistance of these hard formations to the pipeline.

3. Usage scenarios
Pipe pusher: usually used in areas where the pipeline is laid for a short time, such as pipeline installation in indoor buildings. Since the thrust of the pipe pusher is relatively small and easy to control, it is suitable for construction in limited space.

Pipe jacking machine: suitable for areas where the pipeline is laid for a long time, such as urban underground pipelines, tunnels, etc. In these scenarios, the pipe jacking machine can continuously generate stable jacking force to ensure that the pipeline can smoothly cross a long distance.

4. Usage effect
Pipe pusher: It is prone to bending, deformation and other problems during the installation process, and the thrust is affected by air pressure or other power sources, and the instability is relatively large. Therefore, the pipe pusher is more suitable for short-distance pipeline installation.

Pipe jacking machine: It can better ensure the accuracy and strength of the pipeline. Since the pipe jacking machine uses a hydraulic system and a precise guide mechanism, it can ensure that the pipeline keeps moving in a straight line and reduces deviation during the jacking

Then how about Drillto Pipe Pusher?

When the drilling rig is used to do a "small machine to do a big job" project, the pipe pusher can be used when the pulling force of the pipe is insufficient, or when there is a long-distance crossing project that requires assistance. With the pipe pusher, there is an additional guarantee for successful pipe pulling. The pipe pusher can also be used to pull the pipe that has been pulled into the hole out of the hole during engineering rescue in an engineering accident.

The "ZTTG-500" pipe pusher is a trenchless pipe pushing and pulling assistance equipment developed and produced by Zuantong Company in 2014. Once the pipe pusher was launched, it was widely praised by users after construction application. The successful use of projects in Heilongjiang, Shandong, Jiangsu and other places also proved that the ZTTG-500 pipe pusher is a good helper for large-diameter pipe construction.

The pipe pusher mainly solves:

1. Escort the pipeline back-pull-in the process of the drilling rig pulling the pipe, the pipe pusher pushes the pipe at the same time, and works together to complete the pipe pulling work. 

2. Solve the problem of engineering pipeline rescue and handle the dangerous situation of pipe pulling. Pull the pipe out of the hole by using a pipe pusher to avoid pipeline loss and effectively reduce construction risks.
