Pipe Bursting
In this type of pipe installation, a series of cones are pulled through the existing pipe with a cable or chain. The cones break the pipe from the inside creating a cavity large enough to accept new pipe which follows the cone into the host pipe. At the end of the line, the pipe is pulled or pushed into the pit and equipment removed. Then, final connections are made.
Step-by-Step Operation of Pipe Replacement Using Pipe Bursting Equipment
STEP 1: Shore the wall of the hole where the Pipe Bursting Machine will be situated. Using 4x4 timbers assemble a retaining barrier as shown. Brush out debris from the pipe area. The Pipe Genie will be situated against this retaining barrier.
STEP 2: Insert 'Push Tube' and then attach the cable.
STEP 3: Pull cable through and then attach the chain.
STEP 4: Pull chain through pipe
STEP 5: Set frame of Pipe Bursting Machine in the hole. Note Step 1 and ensure frame is butted against retaining barrier as described.
STEP 6: Assemble cylinder(s), pulley and top pulling assembly.
STEP 7: Pass chain around pulley and top box assembly.
STEP 8: Install breaking cones over chain and then install the pipe guide.
STEP 9: Hook up pulling chain to block (flat end forward) and hook up retaining chain.
STEP 10: Hook up hydraulic hoses from cylinders to actuator, and from actuator to the supplied power pack.
STEP 11: Start the power pack, and start pulling cones into the old pipe.
STEPS 12 and 13: [12] Insert chain into new pipe and insert new pipe into the pipe guide.
[13] Pull retaining chain snug and hook up boot. You're ready to begin installing pipe.
STEP 14: Begin pulling until the pipe is in and the boot is at the bank. Repeat these steps (13, 14, 15) until all the pipe is in.
STEP 15 / 15a: [15] When the breaking cones come through, remove them one at a time by releasing the chain coupler, and then finally release the pipe guide. Then [15a] Once pipe is fully through, remove the pipe boot and retrieve the chain.
