Pavement Box Location
Locate the pavement box in a well-drained, level, grassy area which is slightly higher
than the surrounding area. The box should not be subjected to standing water during
and after rain events.
Although the cover will withstand most loads, the boxes are not designed for constant
abuse by traffic. The pavement box should only be installed in a road after all other
options are exhausted. If there is no other location for the pavement box, then select a
stronger pavement box and/or pour a concrete footing to spread out the load and to
increase the stability.
Orient the pavement box so that one end faces the phone source and the other end
faces the manhole as much as possible. This will avoid cable confusion in the manhole
and will meet the IS requirements for cable separation.
When the location is finally determined, obtain the required length of communication
cable, but allow for extra footage. The maximum cable length connecting the EMU to
the QS3600 flow monitor is 90 m (300 ft). Install the pavement box between the
QS3600 flow monitor and the phone source. Keep the cable lengths to a minimum. If
a long cable is required, locate the pavement box as near as possible to the monitor
and run the telephone cable the longest distance.
Underground Services and Lines Location
Search for any underground services that may be buried in the area where the box and
cable trenching is planned.
z Use the proper authorities to conduct this search. Normally, each utility
company provides a location service that visits the site to mark the location
and depth of the underground services to be avoided.
z Be onsite when the underground service locators are conducting their search.
z If the service is of a vital or hazardous nature, request that a member of the
locating service be present during digging. Make this request in writing and
give the date and time when the digging will begin. Services of a vital or
hazardous nature include
Y
gas lines,
Y
steam lines,
Y
fiber optic mass-use phone ducts, and
Y
high voltage power lines.
z The service owners have the right to ask that the trenches be hand dug. Hand
digging avoids the potential damage that a backhoe or other powerful
