Non-excavation technical measures are widely used in modern infrastructure projects to minimize disruption and environmental impact. Depending on the construction requirements, these techniques can be classified into several methods, including directional drilling and pipe laying, shovel shuttle pipe laying, pipe jacking machine technology, and pipe jacking. Each method has its own unique advantages and applications.
1. **Directional Drilling and Pipe Laying Technology**
(1) **Construction Advantages**: This technique uses a guidance system for precise and efficient positioning. It allows for easy control of the drilling direction and requires minimal space on-site. The combination of guidance detection and pipeline detection ensures accurate adjustment of the drill bit, making it ideal for complex geological conditions.
(2) **Scope of Application**: It is commonly used for laying power, communication, gas, and water supply pipelines. The technology supports a wide range of pipe diameters, materials, and lengths, typically suitable for pipes under 1000mm in diameter, mainly for PE and steel pipes.
2. **Shovel Shuttle Pipe Laying Technology**
(1) **Construction Method**: This includes two main approaches: pull tube method and top tube method.
(2) **Construction Advantages**: It offers high impact force and strong penetration capability, allowing it to pass through sandy, muddy, and pebble layers. It is fast, efficient, and suitable for various types of pipelines.
(3) **Scope of Application**: This method is ideal for small-diameter pipelines ranging from 13 to 150mm. It is particularly effective for short-length installations.
3. **Pipe Jacking Machine Pipe Laying Technology**
(1) **Advantages**: This method features high power and efficiency. It uses a mud-water balance tunneling technique, which allows for large-diameter and ultra-long-distance construction. It also produces less noise and no pollution, making it environmentally friendly.
(2) **Scope of Application**: It is suitable for constructing tunnels, culverts, and large-diameter pipes.
4. **Pipe Laying Technology**
(1) **Equipment Used**: Key equipment includes a guidance detector, a directional drilling machine, and a hydraulic pipe jacking machine.
(2) **Construction Method**: The process involves guided drilling orientation, followed by hydraulic jacking or manual excavation.
(3) **Advantages**: This method is cost-effective, provides accurate and safe positioning with high precision, and is suitable for various geological conditions. It is especially useful for small-scale, large-diameter pipeline installations.
(4) **Scope of Application**: It is applicable for laying steel, concrete, and cast iron pipes with diameters up to 3000mm.

Submission: This comprehensive overview highlights the versatility and effectiveness of non-excavation technologies in modern engineering. Whether it's for urban utilities, underground infrastructure, or pipeline installation, these methods offer sustainable and efficient solutions.
Use a thread insert kit to replace a stripped thread or add a threaded insert into sheet metal, fiberglass or other brittle material. Choose from kits with standard inserts or helical inserts (also known as helicoil inserts). Thread repair kits include everything you need to repair or install threaded inserts, including a hand drill and installation tool to speed maintenance and reduce downtime.
