A.
Laying of pipe for storm sewer.
(1)
Description. This item shall consist of laying and backfilling
storm sewer pipe to conform to the type, size lines and grades as shown on
the accepted drawings.
(2)
Material. All materials shall be secured from approved
sources.
(3)
Construction.
(a)
Preparation of trenches for pipe-laying.
[1]
Pipelines shall be placed at a sufficient depth below
the surface of the street to avoid dangerous pressure of impact. When this
is not possible, special reinforcement shall be provided.
[2]
Trenches shall be only of sufficient width to provide
a free working space on each side of the pipe, and in every case, there shall
be sufficient space between the pipe and the sides of the trench to make it
possible to thoroughly ram the backfilling around the pipe and to secure tight
joints.
[3]
Trenches shall be kept free from water until the materials
in the joints, where concrete or clay pipes are used, and masonry have sufficiently
hardened. Where metal pipes are used, the trenches shall be kept free from
water until the bands have been thoroughly tightened and bolted in place.
(b)
Preparation of foundation for pipe-laying.
[1]
The foundation in the trench shall be formed to prevent
any subsequent settlement which might result in excessive pressure and consequent
rupture of the pipes.
[2]
If the foundation is rock, an equalizing bed of concrete
or sand, well-compacted, shall be placed upon the rock. The thickness of these
beds shall be not less than four inches. Pipes shall be laid in these beds
so that at least the lower third of each pipe is supported throughout its
entire length.
[3]
If the foundation is good firm earth, the earth shall
be pared or mouled to give a full support to the lower third of each pipe,
and if necessary, to secure a proper bearing for the pipe, a layer of concrete,
fine gravel or other suitable material shall be placed. The same means of
securing a firm foundation shall be adopted in case the excavation has been
made deeper than necessary.
[4]
If there is no good natural foundation, the pipes shall
be laid in a concrete cradle supported on a masonry foundation, carried to
a soil of satisfactory bearing power, or supported on a structure designed
to carry the weight of a pipe and its load to a firm bearing.
(c)
Pipe-laying.
[1]
The laying of pipes in finished trenches shall be commenced
at the lowest point so that the spigot ends point in the direction of flow.
[2]
All pipes shall be laid with ends abutting and true to
line and grade. They shall be fitted and matched so that, when laid in the
work, they will form a sewer with a smooth and uniform invert. It is necessary
to use all possible care when shoving the pipes together so that the points
will not be unnecessarily large.
[3]
Sockets shall be carefully cleaned before the pipes are
lowered into trenches. The pipes shall be so lowered as to avoid unnecessary
handling in the trench.
[4]
The joints shall be set firmly according to line and
grade and joined together in such a manner that they will be structurally
sound and watertight.
(d)
Backfilling trenches.
[1]
All trenches and excavations shall be backfilled immediately
after the pipes are laid unless other protection of the pipe is necessary.
The backfilling material shall be selected and deposited with special reference
to the future safety of the pipes. Clean earth, sand or rockdust shall be
solidly tamped about the pipes up to a level of at least two feet above the
top of the pipes. This material shall be carefully deposited in uniform layers.
Unless otherwise permitted, each layer shall be carefully and solidly tamped
or rammed with proper tools so as not to injure or disturb the pipeline.
[2]
Puddling or water flooding for consolidating the backfilling
is recommended only for sandy and gravelly materials. If this method is used,
the first flooding shall be applied after the backfilling has been compacted
by tamping up to two feet above the top of the pipes and the second flooding
applied during or after the subsequent filling of the trench. An excess of
water shall be avoided in order to prevent disturbance of the earth under
and around the pipes and also to prevent an undue excess of pressure upon
them.
[3]
Walking or working on the completed pipeline, except
as may be necessary in tamping or backfilling, shall not be permitted until
the trench has been backfilled to a height of at least two feet over the top
of the pipes. The filling of the trench shall be carried on simultaneously
on both sides of the pipes in such manner that injurious side pressures do
not occur.
(e)
Seasonal limits. No construction shall be done during
unfavorable weather conditions.
B.
Manholes and catch basins.
(1)
Description. This item shall consist of the construction
of manholes and catch basins and all necessary appurtenances and shall conform
with the details as shown on the accepted drawings. The work shall include
all necessary excavation for the structures and their appurtenances; the construction
of all foundations; all brick, concrete, stone and timber work; the setting
in place of all iron work; and the refilling of all trenches and any other
work necessary for their completion.
(2)
Materials. All materials shall be secured from approved
sources. All metal castings shall conform with the American Society for Testing
and Materials standards.
(3)
Construction.
(a)
Excavation. Excavation shall be made to the required
depth, and the base upon which the manhole or catch basin is to be constructed
shall be compacted to a firm even surface.
(b)
Forms. For cast-in-place concrete structures, steel or
wooden forms shall be used. The forms shall be braced and wired in such a
manner that they will not give or warp under the pressure and loads contemplated
in pouring the concrete. The concrete shall be tamped or spaded into place
in such a manner as to eliminate honeycombing.
(d)
Brickwork.
[1]
All bricks for brick structures shall be thoroughly wet
by immersion immediately before laying. Every brick must be thoroughly laid
in full mortar joints on the bottom side and end, which for each brick must
be formed by one operation. In no case are the joints to be made by grouting
or by working in mortar after laying the brick. No joints shall exceed three-eighths
(3/8) inch in thickness. All joints on faces shall be trowel-struck.
[2]
All unfinished brick masonry must be racked back or toothed,
and when new work is joined to the unfinished portion, the latter must be
thoroughly cleaned.
[3]
Brick masonry of sides and arches shall be bonded and
keyed, special care being exercised with each ring against two large joints
at the back. All joints shall be normal to the section, and all lipping of
brick must be carefully avoided.
(e)
Pipe setting. Sections of connection pipe shall be incorporated
into the construction and placed at the elevation, direction and grade required.
The inner ends of the pipe shall be flush with the inner faces of the walls.
Inlet and outlet pipe shall be of the size and kind and meet the same requirements
as the pipe with which it is to be connected. Pipe placed in masonry for inlet
or outlet connections shall extend through the walls and beyond the outside
surfaces of the walls a sufficient distance to allow for connections, and
masonry shall be carefully constructed around it so as to prevent leakage
around its outer surfaces.
(f)
Seasonal limits. No construction shall be done during
unfavorable weather conditions.
(g)
Concrete block manholes and catch basins. See Subsection B(3)(d) for the same procedure in construction.
(h)
Cast-iron covers and grates. To be as described and be
set evenly and firm in their frames so that no rocking will occur under loading.
