Non-excavation technical measures are widely used in modern infrastructure projects to minimize disruption and environmental impact. Based on construction methods, these techniques can be categorized into several types: directional drilling and pipe laying technology, shovel shuttle pipe laying technology, pipe jacking machine pipe laying technology, and pipe jacking technology.
1. **Directional Drilling and Pipe Laying Technology**
(1) **Construction Advantages**:
- Utilizes a guidance system for accurate and efficient drilling.
- Easy to control the drilling direction, with minimal requirements for the construction site.
- Combines guidance detection with pipeline detection to adjust the drill bit and avoid obstacles, making it ideal for complex geological conditions.
(2) **Application Scope**:
This technique is commonly used for laying power, communication, gas, and water supply pipelines. It supports a wide range of pipe diameters, lengths, and materials, typically suitable for pipes below 1000mm, especially for PE and steel pipes.
2. **Shovel Shuttle Pipe Laying Technology**
(1) **Construction Methods**:
- Pull-tube method.
- Top-tube method.
(2) **Construction Advantages**:
- High impact force and strong penetration capability.
- Fast speed and short construction period.
- Can pass through muddy, sandy, and gravel layers.
- Suitable for various types of pipes.
(3) **Application Scope**:
- Ideal for laying pipes with diameters ranging from 13 to 150mm.
- Appropriate for small-diameter pipes over long distances.
3. **Pipe Jacking Machine Pipe Laying Technology**
(1) **Advantages**:
- High power and efficiency.
- Uses a mud-water balance tunneling method, allowing for large-diameter and ultra-long construction.
- Low noise and no pollution.
(2) **Application Scope**:
- Suitable for tunnels, culverts, and large-diameter pipes.
4. **Pipe Jacking Technology**
(1) **Equipment Used**:
- Guidance detector.
- Guidance drilling machine.
- Hydraulic pipe jacking machine.
(2) **Construction Method**:
- Guidance drilling orientation.
- Hydraulic jacking and manual excavation.
(3) **Advantages**:
- Cost-effective solution.
- Accurate orientation with high precision and safety.
- No noise pollution.
- Suitable for various geological conditions.
- Ideal for large-caliber and small-scale pipeline construction.
(4) **Application Scope**:
- Applicable for laying steel, concrete, and cast iron pipes up to 3000mm in diameter.
