Seattle Boring - Horizontal Auger Boring Contractors

Horizontal Auger Boring (HAB), often referred to as Jack and Bore, is a widely utilized trenchless construction technique. It is designed for the installation of gravity-flow systems such as sewer lines, drainage systems, and stormwater pipelines. The process enables precise alignment (on line) and slope (on grade) installations under various surface obstructions, including roads, railroads, and municipal infrastructure. Here’s how it works and its relevance to the listed contexts:

Key Features of Horizontal Auger Boring

1. Trenchless Installation:
   • Avoids open trenching, minimizing surface disruption.
   • Ideal for areas with traffic, such as under roads and railroads.

1. On Line and On Grade:

1. • Ensures pipelines are installed to exact horizontal and vertical alignments.
   • Critical for gravity-fed systems where maintaining the correct % fall (slope) is essential for flow efficiency.

1. Versatility Across Applications:

1. • Suitable for various materials (steel, concrete, HDPE) and diameters, supporting systems like:
     • Sewer: Precise slope control for gravity-fed sanitary systems.
     • Drainage and Stormwater: Ensures adequate water flow for infrastructure.
     • Sanitary Lines: Maintains flow and avoids obstructions in municipal wastewater systems.

How It Works

1. Site Preparation:
   • A pit is excavated at the entry and exit points.
   • The bore path is planned based on the required alignment and slope.

1. Casing Installation:

1. • A steel casing pipe is jacked into place using hydraulic jacks from the entry pit.
   • The pipe progresses in segments.

1. Material Removal:

1. • Augers inside the casing rotate to remove soil, transporting it back to the entry pit.
   • This ensures the casing remains on grade and avoids misalignment.

1. Precision:

1. • Laser guidance systems monitor and adjust for precise installation, maintaining the desired line and grade.

Applications

1. Under Roads and Railroads:
   • Minimizes disruption to transportation systems.
   • Meets stringent regulatory standards for surface integrity.

1. Municipal Infrastructure:

1. • Vital for urban environments where surface disruption must be minimized.
   • Handles installations of water mains, sewer systems, and utilities.

1. Gravity-Flow Systems:

1. • Sewer, drainage, and stormwater systems rely on % fall for proper flow:
     • A small slope (e.g., 1-2%) ensures smooth gravity operation.
     • HAB ensures the precise slope required to meet these specifications.

Advantages

• Non-Disruptive: Reduces the need for excavation and surface restoration.
• Cost-Effective: Avoids costly rerouting of traffic and restoration of surfaces.
• High Precision: Ensures reliable installation of infrastructure requiring exact slopes and alignments.
