A manual for geodetic work in construction (to SNiP 3.01.03-84).
Geodetic work when laying pipelines is mandatory integral part technologies for the production of pipeline laying works (self-control, operational control and acceptance control).
Geodetic control means, along with mechanical ones, provide the ability to lay pipelines in the design position (self-control), provide the ability to monitor the compliance of the position of pipelines and its elements with design and regulatory requirements both during installation (operational control) and upon its completion (acceptance control through executive geodetic survey of the planned and altitude position of the laid pipeline).
Before starting work on laying the pipeline, it is necessary to check:
Availability of PPGR, technological map and SOKK or as part of the PPR technological documentation for carrying out geodetic work when laying pipelines, containing methods for performing detailed alignment work, a diagram of the location of signs, marks and landmarks, the order and volume of work performed;
Availability of a road layout certificate; the presence of an as-built drawing based on the results of staking out and fixing the places of connections and connections of communications, angles of rotation of the pipeline, wells, chambers, channels, tunnels, intersections of the pipeline with other networks;
Safety of signs of the external alignment network of the pipeline and axial signs, immutability of their position through repeated measurements of network elements; restoration of lost signs;
Availability of certificates of inspection of previously completed earthworks for the construction of trenches and pits, certificates of acceptance of trenches and pits;
Availability of an as-built drawing (scheme) based on the results of a geodetic check of the compliance of the planned and altitude positions of trenches and pits with the design ones; the presence in the drawing of confirmation by the customer of the correctness of the preparation and compliance of the as-built drawing with nature;
Conducting training for workers in labor organization and methods for aligning pipes and other pipeline elements horizontally and vertically.

Geodetic work when laying pipelines is an integral part technological process production of work. They must be carried out in accordance with the requirements of SNiP 3.01.03-84, PPR, PPGR, operational quality control schemes 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">
Laying out the height of the bottom of trenches, pits and pits and relocating the pipeline axis using fixed and moving sights

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;
