| 6.0 GROUTING |
| |
- The bentonite cement grout shall be injected into the open joint chamber through a grout tube inserted to the bottom of the joint chamber. The same poly pipe used for flushing can also act as a grout tube. The grout injection shall continue until the joint chamber is at least 50% full after which the grout tube shall be progressively withdrawn while grouting continues until the joint chamber is full and the tube has been fully extracted.
- To fill all voids, pumping of grout will be required. Normally, indication that the flowing of water followed by grout out of a joint in a stable consistency is sufficient evidence that all cavities or voids are filled within the range of joint being grouted, and pumping in such joint may cease. Excessive loss of grout shall not be tolerated. And this method shall insure the positive displacement of the water in the clutch, and will minimize dilution or separation of the grout.
- The grouting shall be carried out in one single, continuous operation to fill the entire (6m) of the track. If there is any settlement, the exposed top of the joint chamber must be 'refilled' immediately prior to hardening of the concrete.
