August and September 2022:

(Asphalt Concrete Plant)

From left to right is the white silo which is lime storage that is incorporated into the mix. Next is the cold feed conveyor which brings in the various aggregates into the drum mixer. Behind the cold feed is the drum mixer which dries and mixes the asphalt concrete components. Next is the conveyor that puts the hot mix into a hopper which is weighed and dumped into the haul trucks. You can see the front of the truck being loaded. Next to the truck is the control shack. Next to the control shack is power supply that powers all the electrical needs to the plant.

(Hydro Seeding)

Photos P1-P8 shows CIPP (Cured-In-Place Pie). This method of pipe repair treatment is competitive cost-wise with other pipe repair treatments, reduces traffic delays and is quicker to complete.

The contractor:

Jets the pipe. (cleans pipe with high pressure equipment)
Pulls a plastic sleeve through the pipe to help facilitate pulling the liner through the pipe
Pulls liner through the pipe (orange plastic bag looking material)
Attaches the cans to the liner on both pipe ends (the cans are the disc looking items)
Lightly inflates the liner
Slides the light sled into liner
Inflates liner to full pressure
Pulls light sled, camera and other measuring instruments through the liner
Activates light sled at a controlled rate to cure liner
Removes cans
Peals plastic coat off liner
Trims liner to fit pipe end
PRESTO! The pipe is lined and ready for use

P1: Liner is cut to length at a fabrication shop and spooled. Photo shows unspooling liner into pipe.

P2: Liner is in place. The can is to the right which will be attached to liner.

P3: Placing liner in can which helps pressurize liner.

P4: Pipe end 1 which shows cable coming out of can pulls light sled through the liner.

P5: Pipe end 2 which shows large air tube to pressurize liner and cable energizes equipment.

P6: Photo of final product.

P7: Support Truck 1 which pressurizes liner and supplies power to equipment.

P8: Support Truck 2 which performs other functions such as camera operations. There are other vehicles not shown such as the jetter truck used to clean pipe.
