DRILLED SHAFT DOWNHOLE CAMERA SYSTEM (DHC)
The Downhole Camera System (DHC) is the latest in drilled shaft inspection systems introduced by GPE, inc. The Downhole Camera System was developed because of demand by GPE's clients to be able to visually observe the drilled shaft sidewall soil strata. The Downhole Camera System is easily transported, is very compact and easy to use. The Downhole Camera System is the tool that will safely, quickly, and effectively allow for visual inspection of the excavation sidewalls without having to enter the shaft.
Shaft sidewall conditions have an important effect upon shaft sidewall shear, shear near the bottom of a shaft, and shaft settlement. The Downhole Camera System allows the Owner, Engineer, and Contractor to simultaneously view the shaft sidewalls whether constructed dry or with water. This saves time and money by eliminating the need for multiple inspections and allowing the designer to reduce shaft length due to increased confidence in shaft construction methods and sidewall soil conditions.
The DHC includes a high-resolution color video monitor, a VHS format video recorder, and a condenser microphone. A permanent voice annotated, video tape record is made for each inspection.
