18 depth, unless otherwise specified the balance of the joint shall be
filled with mortar composed of equal parts by volume of cement and
19 sand. No joint shall be filled with mortar until the gaskets have
been placed in the next two ( 2) joints in advance. Water must
20 not be allowed to rise up to or around the pipe until the mortar
has set hard.
21 On the completion of each section of the sewer between man-
j�•. -_. holes , where the soil is wet , the two ends of the sewer at the
22 manholes shall be closed sufficiently to prevent the entrance of
water and tested for leakage , which, if found to occur in such
I �f 23 quantities as would impair the efficiency of the sewer shall be
7 located and stopped. 'There such leaks are discovered before the xnL
24 completion and acceptance of the sewer, the .sewer shall be immed-
iately uncovered and the leaks stoppedo
f 25 The interior of the sewer shall be freed from all dirt and
; 4 foreign material as the work progresses and left clean at its
26 completion.

` 1 the plans. The outside of all structures and brick sewers I s
shall be neatly plastered with mortar one-half (J) inch thick
k 2 as specified in Section 38 hereof. After the plastering on the
interior of flush tanks and flushing manholes has set , the inter- °
3 for surfn.ce shall be coated with neat cement grout put on with a
brush.
_4 4 pipe branches for lateral sewers shall be built into the
structures as shown on the drawings , the outer ends to be closed
5 as specified in Section 35 hereof. In laying pipes up to man-
holes or flush tanks , no pipe shall be allowed to project more
6 than two (2) inches thereinto , and in no. case shall the bell or
hub of a pipe 'be built into the wall od a manhole or flush tank.
7 Where brick work is required in sewers the joints between
courses shall be one-fourth (4) of an inch in thickness and be-
8 tween rings one-half (2) of an inch in thickness. The courses
u in sewers are to be laid to line and kept perfectly straight in
f ' . 9 the direction of the sewer and parallel to the rise of the same.
The brick shall be laid as stretchers and-break joints with those -
10 in adjacent courses. All brick work, as the work progresses
must be racked back in course unless otherwise specified.
11 The invert of the .sewer,, when built of brick, shall be laid
on a bed of mortar one (1) inch in thickness and shall be allow-
12 ed to set for at least twelve ( 12) hours before the arch is
turned. Templates shall be used which are accurately made
13 and correctly set._ The arch of the sewer when .built of brick
shall be laid on strong centers with close fitting joints , of
14 correct form and dimensions according; to' the plans of the sewer.
The centers shall be so constructed that they can be re-
15 moved without cracking or injuring the work; they shall hot,::bL��- j
t�i:t�hdrawn in less than twelve ( 12) hours after the back filling
16 is completed to a level of at least one ( 1) foot above the crown of the sewer. All brick work shall be protected from the
17 rays of the sun by adequate covering, or shall be kept wet until -
j such time as it can consistently be covered with eatth without
18 in any way damaging the work. I
No wheeling,working or walking on brick work will be allowed
19 until it is set. There new work is joined to the surface of
unfinished work the latter must be thoroughly cleaned and moist-
20 ened. `
21 Sec . 41, BACKFILLING: TRENCHES, After a section of pipe
k sewer has been laid and the mortar has sufficiently set , good
22 earth, sand or gravel , free from large stones or hard lumps ,
shall be carefully deposited in the trench so as to fill it up
2Z to, a level two (2) feet above the top of the pipe in such a man-
•ner that the filling placed on each side of the pipe shall be -
24 equal.
The backfilling over a masonry setter to a heighth of two (2)
25 feet above the crown shall be similiarly made as soon as the
outside plastering shall have thoroughly set, provided that at
26 least six (6) hours time shall have expired since the completion
of the plastering. In all cases of backfilling the utmost care
' 27 must be taken to thoroughly compact the material used in refill-
ing the trench below the axis of the sewer.
28 In completing the backfilling of the trenches for pipe sewer
upward from the aforesaid. level of two (2) feet above the top
29 of the sewerthe filling shall be made to within one ( 1) foot of _
the surface of the ground,provided that if the trench is more
- 30 than ten ( 10) feet in depth the filling shall be carried only to
a level ten ('10) feet above sub-grade when it shall be thorough-
31 ly compacted by flooding with water where water is in any manner
P available , and where water is not available it shall be compacted
32 by tamping. Then whatever remains unfilled in the trenches
I � I shall be filled again and compacted by flooding where water is
, e
I in any manner available and where not available the filling shall be compacted by tamping. as before.
2 The completion of the backfilling Ofrthe trenches for mas-
onry sewers shall not be made until the expiration of thirty-
3 six six (36) hours time after the completion of the plastering, at
which time the methods given above for the completion of back-
4 filling over pipe sewers shall be used.
If desired by the Contractor , the backfilling above the i
5 laforesaid two foot level may be made by the use of_ scrapers.
g _
6 Sec. 42, TUNNELS: Before the trenches are backfill-ed above
Ithe aforesaid two foot level specified in Sec . .41, the-.earth above
7 ,all short tunnels connecting sections of open trenches` shall be 1
cut through to the surface of the ground for the full-width of the 1
8 ,1trench where so indicated on the plan or profile. Where not so
,! indicated, the earth above all said short tunnels shall be cut out --
9 ' to a "V" share having the pmint of the "V" at the center of the tqo
' of the tunnel and the slope of the "V" making an angle 'of not less -
10 ' than 45 degrees with the horizontal.
Where tunnels are specified on the plans or profiles they
11 ' shall be completely filled as soon as the sewer is laid and the
mortar in the joints in the joints of the pipe sewers or the out- - - j
12 side plastering of masonry sewers has properly set. This filling JI
. shall consist of earth or gravel free from large stones and shallk
13 be rammed with proper tools until thoroughly compacted.
14 No flooding of tunnels will be required.
Sec. 43 , TUNNEL SHAFTS, MANHOLE SHAFTS, ETC. The backfilling
15 ', of the shafts .shall require the following method: After. the tun-
Inels have been properly backfilled, the shaft excavations , where
16 not coincident with the location of any structure , is to be filled -- ---
ito a depth of not greater than ten ( 10) feet , thoroughly. flooded
17 �jand allowed to settle. The partly filled shaft shall then be- fil- --- j
, led again to a second depth of not greater than ten (10) feet , I
18 flooded and again allowed to settle. The process shall. be contin- --- - - I
cued until after ultimate settling the surface of the filled in
19 �shaft will be at the level of the surface of the- ground. Where - -
�the location of the shaft is coincident with .any structure , a
20 similar process for backfilling shall be used during the progress - - -�of the construction of said structure , providing that the outside
21 plastering has thoroughly set. 1
22 , Sec. 44, SURPLUS MATERIAL. Surplus material not required
in refilling the trench or tunnel shall be promptly removed by
23 the Contractor as the backfilling progresses and disposed of by - -
him.
24
Sec. 45 , UNGRADED STRTMTS: Whenever. the sewer i iff-bui It in a - - — --
25 any ungraded street , the trench shall be refilled to the original
surface of the street , provided , however, that there shall not best -- ----�
26 less than three (3) feet of earth over the sewer , and, provided
further , that where a fill i7 .required on which to constr,uct� ,a - - ---
27 sewer, the fill shall be made of good sound earth; built up in
layers , each layer not more than one ( 1) foot thick and the lay- - --`
28 ers thoroughly compacted by rolling or tamping; ; the width and x
side slopes of such fill will be shown on the plan or profile. --- - -
29 There trenches do not supply sufficient material of the
proper duality for making the fill,. the Contractor shall supply
30 the deficiency.
31 Sec. 46 , RESTORATION OF STREET SURFACE;: In all paved, maces - - -
adamized, graveled , oiled or otherwise -improved streets the sur-
32 face over the trenches shall , after being backfilled, as herein- -- - —
before specified, be finished by the Contractor without delay , in
a workmanlike manner satisfactory to the Superintendent of Streets.
