Abrégé

Systems, methods, and apparatuses related to localized excavation using compressed air are disclosed. A pressure vessel may include a working chamber having an inner space for personnel and equipment, and an opening on the working chamber that surrounds an area for excavation of a second passageway. The main passageway may be a first excavation path and the second passageway may be a second excavation path in a direction different than the first excavation path. A sealing frame, secured to the pressure vessel, forms an airtight seal with the main passageway when positioned around the area for excavation. A load reaction structure stabilizes a position of the pressure vessel in the main passageway and maintains the airtight seal during pressurization. A controller may manage pressure within the pressure vessel during excavation operations.

Classes IPC  ?

• E21D 9/06 - Exécution en utilisant un bouclier de percement
• E21D 9/10 - Exécution en utilisant des machines à forer ou à inciser
