1.1. The requirements of this industry standard
document should be used as a guide when designing transitions
railways pipelines for various purposes - thermal
networks, petroleum product pipelines, oil pipelines, gas pipelines,
sewer pipelines, external water supply networks
water supply, etc., as well as in the design and implementation
measures to eliminate deformations of railway earthen
canvases arising in places of existing intersections with these
engineering communications.
1.2. Crossing railway lines with pipelines is necessary
be provided by overhead installation (on supports or
overpasses) or underground - under the roadbed. At the same time, it should
the prospect of laying additional (second, third and
fourth) main tracks or station developments.
1.3. To the transitions of gas pipelines, oil pipelines,
oil product pipelines, etc. demands should be made on both
areas of higher category.
1.4. When widening the roadbed for laying additional
main tracks or station developments working pipeline in place
intersections must be reconstructed or rebuilt (on a new
axis) taking into account the corresponding increase in the length of the section of increased
category and, if necessary, subjected to hydrotesting.
The protective tube must be extended accordingly.
1.5. In areas of permafrost, transitions
pipelines through railways at stages and stations
should be carried out, as a rule, by overhead laying along
overpasses. Underground installation in these areas can be
provide foundations in soils that do not settle during thawing.
In areas with the occurrence of subsidence when thawing soils on
depth less than 25 m, underground installation is permitted if
designing special measures to prevent
thawing and precipitation based on thermotechnical calculations.
1.6. When designing a railway underpass
pipelines in areas buried in the subgrade
soils subject to frost heaving, it is necessary to carry out
thermal engineering calculations to prevent unacceptable violations
temperature regime and frost heaving of these soils. Uneven
heaving of the railway track in the longitudinal profile is caused by
difference in the depths of freezing-thawing of the soil above
pipeline and outside the zone of its thermal influence. To the susceptible
frost heaving of railway subgrade soils
the following types should be included: clayey (clay, loam,
sandy loam); coarse-grained with clay filler when maintained
particles less than 0.1 mm in size in an amount of more than 20% by weight;
easily weathered rocks (mudstones, siltstones, marls,
shales) in the zone of active weathering; dusty sands
saturating them with water; peats and peaty soils.
At underground railway crossings, the working pipeline
must be enclosed in a protective pipe (channel, tunnel). Laying
pipeline directly into the ground is unacceptable. Thermotechnical
by calculation it is necessary to determine the parameters of the pipeline laying
(laying depth from the base of the rails to the top of the protective pipe and
air temperature in the protective pipe), at which seasonal
deformations of the path from frost heaving will be uniform, not
exceeding the established content standards for this class
ways.
When constructing underground passages or eliminating abysses on
existing intersections, the thermal influence of pipelines on
frost heaving of railway subgrade soils can
be eliminated in the following ways:
- deepening of pipelines by the calculated value;
- reduction of heat loss by thermal insulation of workers
pipelines;
- removal of excess heat from the protective pipe using
natural supply and exhaust ventilation;
- cutting out and replacing heaving soil with drainage soil
calculation in the entire seasonal freezing-thawing zone with
longitudinal mates; thermal insulation made of polystyrene foam with
longitudinal joints.
Each of these methods can be used as
a stand-alone event or in combination with other methods.
1.7. During the underground passage of operating railways
pipeline lines, the open method of penetration, as a rule, is not
allowed.
1.8. When constructing railways over existing ones
pipelines, the working pipeline at the intersection should be
enclose in a protective tube. Replacing the protective pipe or worker
pipeline must be carried out in accordance with the requirements
real standards.
1.9. Pipelines should be located under the subgrade
railway outside the station neck at a distance from the switch points
transfers and other crossings of the path at least 20 m. Minimum
distance from pipelines to artificial structures (bridges,
culverts, etc.) must be provided in
in accordance with the degree of their danger for normal operation
railway, but not less than 30 m, to the points of connection
suction cables to the rails of electrified railways
- 10 m, to the contact network supports - 3 m.
1.10. The design of the railway crossing should
ensure the possibility of periodic inspections, routine repairs,
shutting down and emptying pipelines. At gas pipeline crossings,
oil product pipelines, etc. additionally needed
provide warning and traffic blocking devices
trains in case of danger.
1.11. For underground laying at stages and stations
the pipeline must be enclosed in a protective pipe (channel,
tunnel). At intersections with pipelines transporting
explosive or flammable products (gas, oil, etc.), end
the protective pipe should be located at least 50 m from the base
slope of an embankment or slope edge of an excavation, and in the presence of drainage
structures - from the outermost drainage structure, and on
intersections with water pipelines, sewer lines, thermal
networks, etc. - at least 10 m on each side.
The vertical distance from the top of the protective pipe (channel,
tunnel) to the base of the railway rail should not be taken
less than 2 m, and when constructing a crossing using a puncture method or
horizontal drilling - 3 m. The top of the protective pipe should
be located, in addition, 1.5 m below the bottom of the drainage pipes
structures or the base of an embankment. Arrangement of transitions in the body of the embankment
prohibited.
Burying pipelines crossing the roadbed,
composed of heaving soils should be determined by calculation,
based on conditions under which the influence of heat generation is excluded
or heat drain on the uniformity of frost heaving of the soil. At
inability to provide the specified temperature due to
deepening of pipelines, ventilation must be provided
protective pipe (channel, tunnel), replacement or thermal insulation
heaving soil at the intersection site, overhead laying
pipelines on a trestle or in a self-supporting case.
1.12. At underground crossings of railways in sections
embankments more than 6 m high, as well as on sloped areas (with
slope steeper than 1:5) the intersection design should include
additional measures to ensure the sustainability of earthen soil
canvases. In deep excavations, underground or above-ground crossing
railway pipelines are selected based on
technical and economic comparison of options.
1.13. Transfer of load to the working pipeline from weight
overlying soil and rolling stock is not allowed, protective
the pipe and its connections must be waterproof and designed to withstand
perception of the weight of the overlying soil and moving load from 4
axle freight car 30 t/axle. Cross section dimensions
protective pipe should be taken into account the design of the thermal
insulation of working pipelines. When removing excess heat from
tunnel - protective pipe, its live cross-section should provide
required air flow with natural supply and exhaust
ventilation.
1.14. The length of the protective tube depends on the number of paths on
section of transition of working marks of the roadbed, structure
drainage structures and location of wells.
1.15. The distance from the base of the rail to the top of the protective pipe at

document.
1.16. If it is impossible to lower the air temperature in
the protective pipe is provided with a natural
supply and exhaust ventilation. The protective pipe is
ventilation tunnel and its ends are adjacent to the chambers,
located on both sides of the roadbed. Above the cameras
supply and exhaust shafts are constructed. Supply and exhaust shafts
ventilation systems must communicate only with outside air and
ventilated tunnel. The ventilated tunnel is tightly separated from
ventilation channels of the approach main part of the pipeline
partitions.
1.17. Distance from the place where the gas pressure decreases to
underground passage of the railway gas pipeline should be designated
based on avoiding negative gas temperatures in the area
transition in the annual cycle.

2. INITIAL DATA FOR DESIGN
RAILROAD CROSSINGS BY PIPELINES

2.1. Design of subgrade intersections
pipelines and thermal engineering calculations are made based on
data:
- topographic plan of the transition area, transverse profile
roadbed, as well as path diagrams and placement of various
railway devices near the crossing point;
- engineering geological sections along the axis of the pipeline and
railway;
- composition, properties and strata of soils of the subgrade and
its foundations;
- data on the depth of groundwater and its regime;
- laboratory soil testing;
- long-term average monthly data on air temperature in
winter period;
- data on the magnitude of uniform frost heaving of soils
roadbed at the transition point.
2.2. At the stage of feasibility study of options
transition it is allowed to accept approximate heaving values
subgrade soils equal to 20-40 mm for the European part
Russian Federation and 60-80 mm for roads in the Urals, Siberia and Dalniy
East. During engineering-geological survey the value
uniform path heaving is determined based on the results of two
leveling the path. The first leveling is carried out in the fall with
the onset of negative air temperature, and the second - in
period of maximum soil freezing. As an exception, maybe
be allowed to carry out the first leveling during the period
maximum freezing of the soil, and the second - after complete
thawing of the soil before the start of summer track work. The path is leveled
along the rail heads at points fixed at 5 m intervals, tying them
to a non-bulging benchmark according to the program of Appendix 1 of the Technical
instructions for eliminating heaves and subsidence of the railway track
TsP-4369, approved by the Ministry of Railways on 03/07/86, M., 1987. Length
leveling area is taken equal to 150 m (75 m from the axis
designed crossing in each direction). As an observed
the values ​​of uniform heaving take on its maximum value
at the leveling site. The calculated value of this parameter
determined in accordance with the requirements of the Technical
instructions TsP4369.
2.3. The freezing depth of subgrade soils is determined
calculation using nomograms in accordance with the methodology set out in
Technical instructions CPU/4369.
2.4. The groundwater level (GWL) is established in wells
with a depth of at least 4.5 m, which are laid on the side of the earthen
canvas and beyond (behind the edge of the recess, at the base
embankments). GWL is measured until it is completely established. At
If necessary, the wells will be equipped with a filter for this period.
2.5. Soil samples for laboratory analysis of its physical properties
properties (natural soil moisture, humidity within
plasticity, particle size distribution, density, etc.) are selected
according to the program of Technical instructions TsP-4369. According to analyzes
soils are classified in accordance with GOST 25100-82 “Soils.
Classification".
2.6. After the construction of the railway underpass
pipeline at the end of the winter period, compliance is checked
air temperature in the protective pipe to its calculated value. If
the measured value exceeds the calculated value by more than 5%, then
are taking additional measures to reduce air temperatures in
protective pipe.
The air temperature in the protective pipe (its temperature
surfaces) are determined at the end of winter with exhaust thermometers,
placed inside the pipe. Pipe surface temperature
can also be measured with thermometers that are installed in
well, laid in a section along the axis of the pipeline
2.7. Organization of engineering and geological work along the way,
ensuring the safety of train traffic, safety of people,
fencing of engineering-geological production sites with signals
workings, etc. determined jointly by those responsible
