Geodetic work when laying pipelines is an integral part of the technological process of work. They must be carried out in accordance with the requirements of SNiP 3.01.03-84, PPR, PPGR, schemes operational control quality and other technological documentation of the quality management system operating in the enterprise.
Before starting work on laying pipelines, the position of the pipeline axis must be secured.
The axis of the route is projected into the trench with a theodolite or a plumb line from a tensioned wire between the pivot points of the axis or turning points.
Fixing the position of the axis of the route, especially wells, can be done using castings, arranged on straight sections of the route at a distance of 40-50 m from one another, as well as at turning points. For cast-offs ( edged boards, attached horizontally to the pillars above the trench, or inventory engineering cast-offs) take out and fix the axes between which the string is stretched. From the string, the axis is transferred by plumb lines to the bottom of the trench.
Laying out the design slope of the trench bottom after completing shortfalls and making up for overshoots and breaking out the bottom of pits for sealing pipeline joints can be done using permanent (fixed) and running sights, geometric leveling, optical levels and laser slope clamps. Marks of permanent (fixed) sights attached to inventory cast-offs, or nailed to a wooden cast-off, or installed on the edge of a trench, are made by a level taking into account the design slope of the trench..jpg" height="17"> - design slope of the trench, DIV_ADBLOCK866">

1. Fixed cast-offs 2. Running sights 3. Fixed sights on the edge of the trench
When monitoring using the method of geometric leveling along the axis, every 15-20 m, stakes are driven in, placed at a convenient distance from the axis, they are leveled and on each mark the depth of the trench is written, calculated from the difference between the design mark and the mark of the peg. The depth of the trench is controlled by a rod with centimeter divisions, along which the clamp and slider are mixed. The clamp is fixed at a mark equal to the depth of the trench from the top cut of the peg.
Automatic regulation of the trench depth can be performed using various slope sensors installed on the earthmoving machine (pendulum, electronic level, gyroscope) or using slope sensors installed parallel to the axis of the route separately from the earthmoving machine (string, laser light beam).
Laying out a well pit includes securing the center of the well, installing a cast-off fixed at a distance of 0.6-0.7 m from the edge of the trench, and transferring marks and axes to the cast-off.
Laying pipes in height can be carried out:
When building on a prepared foundation (by beacons) according to the level;

After completion of construction and installation work, heating network pipelines must be subjected to final (acceptance) tests for strength and tightness. In addition, condensate pipelines and pipelines of water heating networks must be flushed, steam pipelines must be purged with steam, and pipelines of water heating networks must be open system heating and hot water supply networks - washed and disinfected.
Pipelines of heating networks laid without ducts and in non-passable channels are also subject to preliminary tests for strength and tightness during construction and installation work.
Preliminary tests of pipelines should be carried out before installing gland (bellows) compensators, sectional valves, closing channels and backfill channelless pipelines and channels.
Preliminary tests of pipelines for strength and tightness should be performed, as a rule, hydraulically.
At negative temperatures outside air and the impossibility of heating water, as well as in the absence of water, it is allowed, in accordance with the PPR, to perform preliminary tests using a pneumatic method.
It is not allowed to carry out pneumatic tests of pipelines laid in the same channel (section) or in the same trench with existing engineering communications.
Pipelines of water heating networks should be tested at a pressure equal to 1.25 working, but not less than 1.6 MPa (16 kgf/cm), steam pipelines, condensate pipelines and hot water supply networks - at a pressure equal to 1.25 working, unless other requirements are justified by the design (working project).
Before performing strength and tightness tests, you must:
Carry out quality control of welded joints of pipelines and correction of detected defects;
Disconnect the tested pipelines from the existing ones and from the first one using plugs. shut-off valves installed in a building (structure);
Install plugs at the ends of the tested pipelines and instead of stuffing box (bellows) compensators, sectional valves - during preliminary tests;
Provide access throughout the entire length of the pipelines being tested for their external inspection and inspection of welds during the tests;
Open the valves and bypass lines completely.
The use of shut-off valves to disconnect the pipelines under test is not permitted.
Simultaneous preliminary tests of several pipelines for strength and tightness are allowed to be carried out in cases justified by the PPR.
Pressure measurements when testing pipelines for strength and tightness should be made using two duly certified (one control) spring pressure gauges of class not lower than 1.5 with a body diameter of at least 160 mm and a scale with a nominal pressure of 4/3 of the measured pressure.
Testing of pipelines for strength and tightness (density), their purging, washing, disinfection must be carried out according to technological schemes(agreed with operating organizations) regulating the technology and safety precautions for carrying out work (including the boundaries security zones).
Reports of the established form should be drawn up on the results of tests of pipelines for strength and tightness, as well as on their flushing (purging).
11.9.1 During production processes and operations, operational controls are carried out in order to identify defects that may be hidden if the process or operation continues, and to take measures to prevent and eliminate these defects.
