constant drainage (if necessary, around the clock) and
pumping of groundwater and atmospheric water that impede the
work.
7. In case of detection during the work of soil not suitable for
further processing, laying in the embankment and compaction to
the required parameters, it is necessary in advance, before the start of such work,
notify and coordinate with the Customer the PPR for its disposal / or
replacement and / or strengthening / stabilization, where a separate item
prescribes the implementation of commission and laboratory control
the quality of unsuitable soil.
9. To control the volume of excavation or backfilling soil, it is necessary
to perform and confirm a geodetic survey and
a mass balance scheme with the geodetic service and the technical supervision
of the Customer BEFORE any excavation work begins and AFTER each stage
of such work is completed.
10. The scope of work on the storage of soil in the collars, without
compaction, are closed by executive survey of collars, with
a coefficient of 0.9.
11. Before the start of work, perform experimental soil compaction in
laboratory and field conditions according to GOST 22733, perform
test sections of compaction.
As a result of experimental compaction, the following should be established:
a. maximum values of the density of compacted soils.
b. optimal humidity at which maximum
compaction densities are achieved.
c. permissible ranges of humidity changes of the compacted soil.
d. thickness of the layers to be poured, the number of passes of sealing machines
in one track, the duration of exposure of vibration and
other working bodies to the soil, and other technological
parameters that ensure the design density of the soil;
13. The filling of soil on the frozen layer and the base is not
allowed.
14. The embankment is carried out on a prepared, compacted
base, with layer-by-layer compaction by ground rollers with
vibration. The thickness of one poured layer of the mound is no more than
0.30m, until the maximum density is reached.
15. The degree of compaction of each layer and base (operational
control) should be taken at the rate of at least 1 test for every 300 m2
