1. Pipeline Installation
The core function of a Pipe Jacking Machine is to precisely push pipes to the designated underground location. This machine works underground, using a mechanical pushing device to install various types of pipes such as steel pipes, concrete pipes, and plastic pipes. Pipe jacking machines can handle different pipe sizes, making them versatile for various project requirements.
Application Example: In municipal engineering, especially for the construction of sewage pipes and drainage systems, pipe jacking machines can complete pipeline installation quickly and efficiently, minimizing disruption to the surface environment. This is particularly important in areas with heavy traffic or where operations like airports, shopping malls, or hospitals need to continue without interruption.
2. Avoiding Surface Excavation
Traditional pipeline laying methods typically require large-scale surface excavation, which disrupts traffic flow, affects the quality of life for residents, and increases environmental pollution during construction. A pipe jacking machine works by pushing the pipeline underground, eliminating the need for extensive surface excavation and causing minimal disruption to surface activities.
Advantages:
Reduced Impact on Traffic and Buildings: In urban centers, this eliminates the need for large-scale excavations, avoiding traffic congestion and road closures.
Avoids Secondary Pollution: Traditional open-cut excavation may result in noise, dust, and the piling of waste soil, while pipe jacking has a smaller environmental footprint.
Application Scenarios: For example, laying sewage or utility pipelines in city centers, where avoiding disruption to existing buildings, roads, and other underground facilities is crucial. In such cases, pipe jacking is especially important.
3. Adapting to Complex Geological Conditions
Pipe jacking machines are capable of adapting to different underground geological conditions, such as loose sand, wet clay, hard rock, and more. These machines are typically equipped with powerful thrust systems and various drilling methods that automatically adjust according to the geological conditions.
Application Example:
Loose Soil Areas: The pipe jacking machine can adjust thrust pressures to prevent misalignment or collapse.
Rocky Areas: With specialized cutting tools, the machine can effectively operate in hard rock layers.
Waterlogged Zones: Pipe jacking machines can be designed to cope with high groundwater levels, preventing underground water from affecting pipe installation.
Advantages:
High Adaptability: Whether in loose soil, clay, or hard rock, the machine can respond flexibly to changing conditions.
Reduced Construction Risk: Complex geological conditions often increase the risks of traditional excavation, but pipe jacking, with its enclosed operation, reduces such risks.
4. Precision Pipeline Alignment
Pipe jacking machines are equipped with advanced control systems, such as laser guidance systems and electronic monitoring equipment, to ensure the pipeline is pushed in the correct direction and aligned accurately. The real-time monitoring system allows adjustments to be made to the direction and positioning of the pipe, minimizing errors and ensuring precise pipe connections.
Advantages:
Increased Construction Accuracy: Precise alignment ensures smooth pipe connections, reducing the chances of leaks or failures at joints.
Reduced Margin of Error: High-precision positioning ensures smooth pipeline installation, minimizing the need for rework or additional costs due to alignment errors.
Application Scenarios: In critical pipeline installation points or complex crossings, accurate alignment is essential, such as when connecting to city wastewater treatment plants or laying long-distance gas pipelines.
5. Reducing Construction Time and Costs
Traditional pipeline installation methods often require extended construction periods due to the need for excavation and restoration work. Pipe jacking, on the other hand, can significantly shorten the construction timeline because the machine works continuously underground, unaffected by weather or surface conditions.
Cost Advantages:
Saves Labor and Equipment Costs: The mechanized operation of pipe jacking machines reduces the need for manual labor and additional construction equipment.
Reduces Surface Restoration Costs: As there is no large-scale excavation, the need for surface restoration is minimized, leading to reduced additional costs.
Increases Construction Efficiency: With continuous operation and higher speed, the machine reduces the time and costs associated with prolonged construction periods.
Application Example: In large-scale projects like urban underground network renovations or long-distance water pipelines, the pipe jacking machine can significantly enhance project efficiency, reducing both constr
uction time and costs.
6. Suitable for Urban Dense Areas
In densely populated urban areas, traditional pipeline installation methods are often difficult to implement because they require a large amount of road space and severely disrupt traffic and daily life. Pipe jacking, with its enclosed operation and precise positioning, is ideal for underground construction in these areas, particularly in busy city centers or residential districts.
Advantages:
Adaptability to Complex Environments: Urban areas often have many underground facilities such as electricity, communication, and water pipelines. Pipe jacking machines can precisely navigate these obstacles, preventing damage to existing infrastructure.
Improves Feasibility of Urban Infrastructure Projects: Pipe jacking enables pipeline expansion and new installations in urban areas, where traditional excavation may not be feasible.
Application Scenarios: For example, in transportation hubs or other busy city centers, pipe jacking machines allow for pipeline installation without disrupting surface traffic, offering a more flexible solution for urban infrastructure projects.
