| dc.description.abstract | Road engineering is quite important in public utility project. Road construction
substantially affected the living quality. Techniques development of Civil Engineering
and the standards set up by Transportation authority render road work progress in
every plan, design and construction aspect. No matter it was newly built, refurbished
one or roadway widened, best function performance can be brought on, by careful
choices on structure, construction method and pavement materials, associated with
suitable design, construction quality control and job evaluation.
Utility conduit construction, including Telecom, Electricity, etc., is the major
pavement killer on the road, and also the one responsible for the lousy performance of
the road. Routine civil work of utility company includes deployment, maintenance
and movement of conduit (and cable). All the jobs have to break the pavement,
excavate the road foundation, lay down the conduit and recover the roadway site. Due
to the traffic, the backfill compaction is seldom executed as required by standard. In
that case, settlement along the route and the heave on the manhole coverlid are often
to be observed. Bumping along the road implies lowering the service level, and in
some case, may even cause the traffic accident. Therefore, construction of conduit
requires concern in every detail to avoid the hazards.
Manhole coverlid bumping on the road can be due to poor manhole embedment
work or pavement construction. This thesis focuses on the issue of aftermath and the
remedial method coping with leveling manhole coverlid to the road crust surface.
Overview of the innovations and research pertaining to the problem well disclosed
that it could be solved. Try the very best to maintain flatness and smooth of the road
symbolized the responsibility and the service quality image of utility company. | en_US |
