Underground Utilities
Glass Machinery & Excavation has the ability and expertise to perform jacking and boring and directional boring projects in many different applications. We can perform varying sizes of boring projects from 4 to 36 inches in diameter.
Horizontal Jacking and Boring:
Pipe ramming is the ideal method for crossings under highways and roadways, electrical and fiber optics, environmentally sensitive areas like rivers and streams, pipelines, and utilities. A pneumatic tool and first pipe section are lowered into the starting pit and placed on adjustable bearings. The pipe is then precisely aligned and the tool firmly secured to the pipe by means of chains and straps to ensure that full impact is transmitted to the pipe. The ramming tool is connected to an air compressor and the section driven or hammered into the soil. A second section of pipe welded squarely into place will then be driven in. This process is continued until the bore is completed. The soil that has accumulated within the pipe can then be removed by using an auger, thus forcing soil out and leaving cleanly installed steel sleeves. This method of installation is very common for water and sanitary sewer system installations, and is widely used for larger diameter piping where open-cut trenching is not practical.
Directional Boring:
Directional boring, commonly called horizontal directional drilling or HDD, is a steerable, trench-less method of installing underground pipes, conduits, and cables in a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area. Directional boring is used when trenching or excavating is not practical. It is suitable for a variety of soil conditions and jobs including road, landscape, and river crossings. This type of installation is especially practical for smaller diameter piping installations such as water service lines and electrical conduit.
Glass Machinery is well-versed in each of these types of trench-less construction. Let us provide a proposal for your underground installation today!
