Combination devices for surface crack filling

摘要

The disclosed port device has a tube with a base that can be permanently bonded to a surface with its outlet throughbore aligned with a crack therein, for funneling the material into the crack; and the port device tube can have a low silhouette of possibly +E,fra 3/8+EE '' high overall, suited for leaving the device in place after crack filling had been completed. The material under pressure can be communicated to the port device via a flexible hose connected between special fittings, that respectively can be seated across leakproof joints established with the material dispensing system and with the port device. This means that the material dispensing system can be well spaced physically from the crack itself, by almost the hose length, and that the operator need not hold the material dispensing system relative to the crack. A clamp on the hose between the fittings, can operate when closed to preclude or restrict material flow therepast, allowing upon user manipulation of the clamp the control of the material flow into the crack from locations spaced from the dispensing system.
