Systems and methods for underground pipe installation

Abstract

Systems and methods for installing pipe underground are disclosed. The system includes a pneumatic rammer configured to provide a percussive force to a section of pipe. The system also includes a mainjacking frame coupled to the pneumatic rammer, the main jacking frame including a surface for contacting the section of pipe. The system also includes one or more hydraulic jacks coupled to the mainjacking frame and configured to provide a hydraulic force to the section of pipe. The system also includes a set of tracks coupled to the main jacking frame, the set of tracks permitting the main jacking frame to slide in a longitudinal direction. An independently displaceable soil-clearing system can be included to clear dirt coming inside the pipe during the installation and add extra jacking force as needed.

Description

[0001] Cross-reference related application [0002] This application claims the rights of US Temporary Patent Application No. 62 / 629, 865, filed on February 13, 2018, US Temporary Patent Application Serial No. 62 / 629, 865, of the Trenchless Pipeline Installation Method and Apparatus The whole is incorporated herein by reference. Technical field [0003] The present invention generally relates to systems and methods for mounting the underground portion of the conduit, which includes pipelines, gaseous tubes, water supply and sewer lines, utility pipelines, and other utilities. More specifically, the present invention relates to a trench-free underground pipe mounting, such as one or more installations of a dirt extraction process suitable for using a hydraulic top feed force, a pneumatic impact force, and a soil that enters the pipe inside the pipe. Tools and methods for new pipelines. Background technique [0004] Various applications require the mounting of the underground duct b...

Problems solved by technology

All of these undesired effects are amplified with drive length, limiting the method to relatively short drives (typically less than 300 feet)

[0014] Furthermore, all of the above grooveless methods have their own limitations and applicability depending on length, diameter, accuracy requirements and land conditions

Also, all of these machines are designed to overcome the maximum length and diameter they were originally conceived, even if for shorter drives or smaller diameters this would mean an excess of energy

Finally, most of the machines listed above (especially those based on the pipe jacking method) have their major components dimensioned for a specific pipe diameter, and each time a new diameter must be installed, the Significant investment in new custom section
