STEP 21 Logging is easy and performed by hand. The information is used to maximize the system performance. |
|
STEP 22 After logging, the final depth is determined. The hole is to be reamed to a final diameter of eight inches. This photo shows the eight inch bit. |
|
STEP 23 The drilling process is continued until the final depth of 200 feet is reached by the eight inch bit. The log showed low resistance clay between 80 to 200 feet. The active column will be between 160 to 200 feet. |
|
STEP 24 The perforated casing in the active zone allows protective current to flow from the anodes to the earth. Since the casing is plastic, permanency of the deep hole is maintained. Forty feet of perforated casing was placed at this site. Note the plug placed on the bottom end to prevent unwanted waste intrusion during installation. |
|
STEP 25 The four inch perforated casing is inserted into the eight inch drilled hole. Go to Replaceable Deep Anode to see a drawing. |
|
STEP 26 This photo shows the first joint of perforated casing entering the drilled hole. This system was designed to discharge eight amps. |
|
STEP 27 The second joint of perforated is added to be followed by solid four inch casing to the earth's surface. |
|
STEP 28 Solid casing is installed from the top of the perforated casing to ground level. The solid casing maintains hole integrity and prevents current from being discharged at the earth's surface. |
|
STEP 29 The casing is joined by glued couplings. Only one minute is allowed for curing. Installation is fast. |
|
STEP 30 The pipe is supported during the one minute cure time. |
|
STEP 31 Once the casing has been installed to the design depth, the anodes are readied for installation. |
|
STEP 32 The 1" x 60" mixed-metal oxide anodes are to be strapped to a 3/4 inch AllVent. The anodes and vent will be lowered together. |
|
STEP 33 The anodes are held against the vent by a top and bottom strap. This photo shows the strap. The wire is taped to the backside of the vent to avoid wire contacting the anode surface. |
|
STEP 34 The anodes and AllVentTM are inserted into the replaceable casing like a flexible tube. The AllVentTM and anodes are inserted in one continuous motion. |
|
STEP 35 This photo shows the flexibility of the system as it is being inserted. Insertion takes 10 minutes. |
|
STEP 36 After the AllVentTM and anodes have been installed, a one inch steel pipe is lowered to the bottom of the system. The one inch steel will be used to pump Loresco® SC·3 from the bottom up. |
|
STEP 37 Pumping of the SC·3 is a continuous process. Water and SC·3 are mixed and pumped down the one inch pipe at the same time. SC·3 is pumped to a level of about 40 feet above the top of the active zone. |
|
STEP 38 The SC·3 and water are mixed in a small 100 gallon tank, and the fluidized SC·3 is pumped down into the system. SC·3 and water are added continuously until the correct amount is installed. |
|
STEP 39 As seen here, by mixing the SC·3 with the proper proportion of water, it is possible to pump the carbon into the deep anode system without loss of carbon at the surface. |
|
STEP 40 After pumping the SC·3, the one inch pipe is removed and PermaPlug is placed around the upper portion of the casing. PermaPlug will prevent surface water intrusion into the deep system. |
|
STEP 41 The casing is cut off below ground level. The cover will be placed over the system, and the lead wires run to the rectifier. Installation took 12 working hours. |
|
STEP 42 Due to the congestion of the area, a traffic rated cover will be installed over the deep system. Go to Replaceable Deep Anode to see a drawing. |
