2018年10月17日 · Learn about different methods and what type of projects they’re used for. Trenchless tunneling methods have literally changed the shape of laying and maintaining underground piping and utilities over the last 50 years. From an innovative fringe idea, it has become a specialized sector of the construction environment.

installing utility tunnels and conduits by thrusting pipes through the ground as controlled excavation is undertaken at the face. Pipes manufactured in a variety of materials to include concrete, clay, grp and steel can be jacked and standard pipe diameters generally range from 150mm to 2,400mm, or greater when required.

管隧（pipe tunnel）是1996年公布的航海科学技术名词。

Pipe jacking method involves the installation of a pipe (prefabricated) through the ground. The driving takes place from a drive shaft to the reception shaft. The drive shaft consists of jacks, that moves the pipe. During the execution of the process, the hydraulic jack makes use of thrust power to move the pipe forward into the ground.

2020年3月1日 · Review of the history and development of pipe jacking and microtunneling methods. Planning, design and construction aspects of the technologies are discussed. Emphasis on academic research into the critical design and construction aspects. Jacking force estimation and effect of lubrication receive particular attention.

2023年9月27日 · Pipe jacking and microtunneling are both trenchless techniques for installing pipes, they differ in several ways. Factors such as pipe diameter, installation length, project budget, access requirements, and surface disruption should be considered when deciding which technique to use.

2015年1月28日 · 在内底和船壳板之间沿船中部船首线和船尾线的空舱，形成船底污水、压载物和其他从机舱延伸至船舱的管线的保护处所。

Micro Tunneling (M/T) is a process that uses a remotely controlled Micro Tunnel Boring Machine (MTBM) combined with the pipe jacking technique to directly install product pipelines underground in a single pass. This process avoids the need to have long stretches of an open trench for pipe laying, which causes extreme disruption to the community.

The void space running in the midships fore and aft lines between the inner bottom and shell plating forming a space for ballast, bilge and/or fuel lines. Wärtsilä is a global leader in innovative technologies and lifecycle solutions for the marine and energy markets.

Pipe jacking and tunneling are trenchless technology methods where pipe is installed, or a tunnel lining is created using a Tunnel Boring Machine (TBM) or Excavator
