Trenchlesspedia Explains Spacer Block
An individual spacer block might be a square steel frame supporting a circular frame the size of the pipes which will pass through it. When multiple pipes or conduits are installed in the same bore, they must be separated to prevent damage.
When the spacer blocks are installed on the conduit or pipe, this means the bore must be large enough to accommodate the dimensions of the spacer block or blocks to be installed. The trench was contractor must be aware of the dimensions of the assembled spacer block and pipe unit.
