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 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 by executive geodetic surveying the planned and altitude position of the laid pipeline).

Before starting work on pipeline laying, it is necessary to check:

Availability of PPGR, technological map and SOKK or as part of the PPR technological documentation to carry 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 inspection certificates 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 on labor organization and methods for aligning pipes and other pipeline elements horizontally and vertically.

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, 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 route axis, 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 earth-moving machine (pendulum, electronic level, gyroscope) or using slope sensors installed parallel to the route axis separately from the earth-moving 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;

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.

11.9.2 With operational control, the person carrying out construction checks:

Compliance of the sequence and composition of the technological operations performed with the technological and regulatory documentation applicable to these technological operations;

Compliance with technological regimes established by technological maps and regulations;

Compliance of quality indicators of operations and their results with the requirements of design and technological documentation, as well as regulatory documentation applicable to these technological operations.

11.9.2 During the construction process, an assessment of the work performed, the results of which affect safety, must be carried out object, but in accordance with the adopted technology become unavailable for control after the start of subsequent work, as well as completed building structures and sections of utility networks, the elimination of defects identified by inspection is impossible without dismantling or damaging subsequent structures and sections of utility networks. Representatives of the relevant state supervision bodies, designer’s supervision, as well as, if necessary, independent experts may participate in these control procedures. The contractor notifies the other participants of the timing of these procedures no later than three working days in advance.

11.9.3 The results of acceptance of work hidden by subsequent work, in accordance with the requirements of design and regulatory documentation, are documented in certificates of inspection of hidden work ( Appendix M ). The developer (customer) may require a re-inspection after eliminating the identified defects.

11.9.4 To the procedure for assessing the conformity of individual structures, tiers of structures (floors), the work performer must submit inspection reports of all hidden works included in these structures, geodetic as-built diagrams, as well as test reports for structures in cases provided for in the design documentation and (or) construction contract. The developer (customer) can check the accuracy of the as-built geodetic schemes presented by the contractor. For this purpose, the performer of the work must preserve the alignment axes and installation guidelines fixed in kind until the completion of acceptance.

The results of acceptance of individual structures must be documented in acceptance certificates for critical structures ( Appendix N ).

11.9.5 Tests of sections of utility networks and installed utility equipment are carried out in accordance with the requirements of the relevant regulatory documents and are documented in acceptance certificates for critical structures (Appendix H).

11.9.6 If defects in work, structures, or sections of utility networks are discovered as a result of stage-by-stage acceptance, the corresponding acts must be drawn up only after the identified defects have been eliminated.

In cases where subsequent work must begin after a break of more than 6 months from the completion of phased acceptance, before resuming work, these procedures should be repeated with the execution of the relevant acts.

11.9.7 Places for performing control operations, their frequency, performers, methods and measuring instruments, forms for recording results, the procedure for making decisions when identifying non-compliance with established requirements must comply with the requirements of design, technological and regulatory documentation.

11.9.8 The person carrying out the construction appoints with his administrative documents the responsible executors for performing operational control, documenting its results and eliminating defects identified by the control.

The results of operational control must be documented in special work logs.
