Reinforced Concrete Pipe Tie- Ins
We have worked with and managed the operations one Philadelphia's most skilled excavators. This is an installation behind the new Lowe's shopping center in west Philadelphia.
The process of making a tie-in to a reinforced concrete pipe involves excavating in the location down to the depth of the existing pipe. Once exposed to a suitable depth where men can work, a hole is cut into the existing pipe both by hand and mechanical means. The inside of the pipe is cleared of debris from the cut out and prepped to receive the hub. The hub is inserted into the hole and supported by masonry blocks to achieve the required pipe slope.
The hub is cemented into place. After this phase is completed backfill material is placed around the tie-in hub and worked outward to support the length of pipe to be connected to it. This operation takes place several feet below grade. (surface). In this condition, the depth was approximately 25 feet below grade steel sheet piles were used to whole back the earth.
The new length of pipe is then placed on top of additional backfill material maintaining the established slope. This connection is also sealed with cement.
The entire connection then sealed by encasing it in concrete poured from above. The excavator is responsible for making the access to the work area safe for other suppliers to access the work area. A site compacted site ramp had to be constructed by the excavator to allow access for the concrete truck. The ramp had to be suitable to carry the weight of concrete truck fully loaded with concrete.
Concrete is cleared from the top of the 24" pipe to allow for inspection by the engineer.
