5.6. In the production of engineering and geodetic surveys of linear structures, the geodetic basis is the points (points) of the planned high-altitude survey geodetic network created in the form of main passages laid along the route.
The main passages of the survey geodetic network in the surveys of linear structures must be tied in plan and in height to the points of the state or reference geodetic network at least 30 km apart (for surveys of the main canals, 8 km).
When removing points of the state or reference geodetic network from the route at a distance of more than 5 km, it is allowed to determine, instead of the planned binding, at least every 15 km, the true azimuths of the sides of the main course. Methods for determining true azimuths and requirements for measurement accuracy should be established in the survey program.
When surveying linear structures in the territories of towns and other settlements, as well as industrial (agro-industrial) and mining enterprises, the planned and high-altitude binding of the survey geodetic network to the points of the state or reference geodetic network is mandatory.
5.7. The geodetic basis for creating plans for the coastal zone of rivers, seas, lakes and reservoirs should be created in a single system of coordinates and heights with points of adjacent land.
On the territory of settlements, engineering and hydrographic work is carried out in the coordinate system of the settlement in the accepted layout of topographic (engineering and topographic) plans.
5.8. The systems of coordinates and heights when performing engineering and geodetic surveys should be established during the registration (issuance of a permit) for the production of engineering surveys by the relevant architectural and urban planning authorities of the executive power of the constituent entities of the Russian Federation or local self-government, as well as in the prescribed manner by the bodies of the State Geonadzor of Roskartografii.
Note
For geodetic points taken as initial, extracts from the catalogs of coordinates and heights, certified by the organizations that issued these data, should be compiled.
Reference geodetic network
5.9. The reference geodetic network should be designed taking into account its subsequent use in geodetic support for the construction and operation of the facility.
The density of points of the reference geodetic network during the production of engineering and geodetic surveys should be set in the survey program based on:
at least four points per 1 km 2 in built-up areas;
one point per 1 km 2 in undeveloped areas.
The marginal error (limiting error) * of the mutual planned position of adjacent points of the reference geodetic network after its adjustment should not exceed 5 cm.
* Hereinafter referred to as "limit error".
5.10. The planned position of the points of the reference geodetic network during engineering and geodetic surveys for construction should be determined by the methods of triangulation, polygonometry, trilateration, construction of linear-angular networks, as well as on the basis of the use of satellite geodetic equipment (GPS receivers, etc.) and their combination.
Altitude binding of the centers of points of the reference geodetic network should be carried out by leveling IV class or technical (trigonometric) leveling, taking into account the types of centers laid down, as well as using satellite geodetic equipment.
5.11. When constructing a reference geodetic network, the requirements given in Appendix B must be observed.
Methods for determining the coordinates and heights of points (points) of geodetic equipment (Appendix G), measuring the lengths of the base (output) sides in triangulation, as well as measuring the lengths of the sides in polygonometry with light range finders and electronic total stations should be adopted based on the requirements for measurement accuracy and instructions from firms (enterprises ) - manufacturers of these devices.
5.12. The fixing of points of the reference geodetic network on the ground and their external design should be carried out in accordance with the requirements of the regulatory documents of Roskartografiya (“Rules for laying centers and benchmarks at points of the geodetic and leveling networks of the USSR”) and taking into account the requirements of production and industry (departmental) regulatory documents for the production engineering and geodetic surveys for certain types of construction (hydrotechnical, energy, transport, reclamation, etc.).
It is advisable to combine the centers of the planned geodetic network and the benchmarks of the leveling lines.
It is allowed, in agreement with the body that registers (issues permits) for the production of engineering and geodetic surveys, to use the types of centers and benchmarks, the design of which differs from those established in the regulatory documents of Roskartografii, provided that their stability, long-term preservation, external design and environmental protection are ensured (preservation of valuable lands, plantations, etc.).
Note
The protection of points of the reference geodetic network must be carried out in accordance with the "Regulations on protected zones and the protection of geodetic points on the territory of the Russian Federation" (Decree of the Government of the Russian Federation of October 7, 1996 No. 1170).
5.13. Leveling marks must be laid in the walls of capital buildings and structures built at least two years before the laying of the mark.
Ground benchmarks should be laid only in the absence of capital buildings (structures) near the location.
Leveling from wall marks and benchmarks is allowed no earlier than three days after their laying, and from fundamental and ground benchmarks - no earlier than 10 days after backfilling the pit.
In areas where permafrost soils are distributed, fundamental and ground leveling benchmarks can be used for:
pit method of laying the benchmark - in the field season following the laying;
laying the benchmark by drilling - not earlier than 10 days after laying;
laying the benchmark by drilling with soil thawing - not earlier than two months after laying.
Note
The coordinates of ground (fundamental) benchmarks are determined by instrumental measurements or graphically according to plans (maps) of the largest scale.
5.14. A continuous triangulation network must be supported by at least three reference geodetic points and at least two reference sides.
The chain of triangles must be based on the initial geodetic points and the two initial sides of the geodetic network of a higher class (category) adjacent to them.
In independent triangulation networks that are not based on points of the highest class or category, at least two basic (output) sides are measured.
5.15. When installing geodetic signs in the form of special metal or wooden superstructures on buildings (structures), the possibility of transferring the coordinates of these signs to the centers of polygonometry (preferably to wall signs) with the measurement of at least two bases should be taken into account.
Places of installation of geodetic points (signs) on buildings and structures of the built-up area must be agreed with the architecture and urban planning authorities of the executive power of the constituent entities of the Russian Federation or local government.
5.16. The coordinates of the center of the triangulation point installed on the building should be taken down to the ground using an electronic total station or theodolite and a light rangefinder. Demolition of coordinates should be carried out simultaneously on four ground working centers located in pairs in opposite directions. Each working ground center must be secured with two wall signs. In this case, the distance between adjacent working centers must be at least 200 m, and the accuracy of measuring angles and lines must correspond to the accuracy of the polygonometry of the corresponding category.
5.17. In a built-up area, in the absence of signs of the state and (or) reference geodetic networks or local objects (spires of prominent buildings, water towers, etc.) visible from the ground (from a tripod above the center of the point), at each point of triangulation (trilateration) at a distance not less than 500 m from it, two landmarks should be installed, fixed by ground centers of the type "5 g.r." or "6 years old".
In a closed (forest) area, the distance between the geodesic point and landmarks may be reduced to 250 m, while the landmarks must be spaced over 50 m.
In the case of adjoining the points of triangulation (trilateration) of polygonometric passages, reference signs are not installed at the points.
5.18. The reduction elements (centering and reduction) on triangulation signs (signals, pyramids) should be determined twice: before observations and after them.
The lengths of the sides of the error triangles obtained by graphical determination of the reduction elements should not exceed 10 mm.
Linear differences between two adjacent definitions of centering or reduction shall not exceed 10 mm.
5.19. When determining the heights of triangulation points installed on buildings, as well as in mountainous areas, by the method of trigonometric leveling, the measurement of vertical angles with theodolites of the 3T2KP type (equivalent to it) should be carried out in three full steps along the middle thread in the forward and reverse directions. In this case, fluctuations in the values of vertical angles and "zero place", calculated from individual methods, should not exceed 15.
The difference between forward and backward elevation shall not exceed 10 cm per kilometer of side length.
Permissible residuals of trigonometric leveling, calculated along the running lines between the starting points of the network, the heights of which are determined by the method of geometric leveling, as well as in closed polygons formed by the sides of the geodetic network, should not exceed the value cm, where L- the number of kilometers in the course.
5.20. A separate course of polygonometry should be based on two starting points and two starting directional angles. The application of polygonometry hanging moves is not allowed.
Allowed in the absence of visibility from the ground to adjacent points:
continuation of the course of polygonometry of 1 and 2 categories, based on two starting points, without angular binding to the original directional angle on one of them;
laying a closed course of polygonometry of 1 and 2 categories, based on one starting point and one initial directional direction, provided that the directional angle is transmitted or measured from the points of the course of the directional angle with an error of no more than 15 in a weak place (middle of the course).
coordinate binding - by laying the polygonometry path between two starting points without transferring the initial directional angles to them, while in order to detect gross errors in angular measurements, directional angles to landmarks or azimuths obtained from astronomical and other measurements should be used.
5.21. The high-altitude reference geodetic network in the territory of engineering and geodetic surveys is being developed in the form of leveling networks of II, III and IV classes, as well as technical leveling, depending on the area and nature of the construction object.
The starting points for the development of a high-altitude reference geodetic network for construction are the points of the state leveling network.
The leveling network should be created in the form of separate passages, systems of passages (polygons) or in the form of an independent network and be tied to at least two initial leveling marks (benchmarks), as a rule, of the highest class.
It is allowed to link the leveling lines of the reference geodetic network of class IV to the benchmarks of the state leveling network of class IV.
5.22. Processing of the results of field measurements during the creation (development) of the reference geodetic network should be carried out using modern computer technology.
Adjustment is performed by methods that ensure control of the obtained results and exclude random miscalculations in data processing.
Adjustment of the planned reference geodetic network of class IV and the leveling network of class IV should be carried out using the least squares method.
Condensation geodetic networks of 1st and 2nd categories may be adjusted using simplified methods. In this case, the results of calculating the values of angles should be rounded up to whole seconds, and the values of line lengths and coordinates should be rounded up to 1 mm.
Programs for automated processing of measurement results during the creation (development) of reference geodetic networks should provide for printing:
initial information;
score results;
evaluation of measurement accuracy.
5.23. When processing the results of measurements in geodetic networks, you should use office processing software that has the appropriate passports, in accordance with the Regulations on the Federal Fund for Mass-Use Software in Construction (approved by the order of the Gosstroy of Russia dated September 18, 1997 No. 17-18) or certificates.
Planned-altitude survey geodetic network
5.24. The survey geodetic network is built in the development of the reference geodetic network or as an independent
