Brief description of the object

For a relative elevation of + 0.000 (146.40), the elevation of the terrain is taken .

The tubular support of the billboard is designed with a diameter of 1420x14 mm of grade 09G2S12 according to GOST 1928189. The height of the tubular support of the billboard is 26m. Tubular support barrel is made composite in height and consists of 4 sections: - ST1 L = 2700mm, weighing 4750kg; - ST2 L = 10500mm, weighing 5100kg; - ST3 L = 9600mm, weighing 5245kg; - ST4 L = 3200mm, weighing 3040kg;

The lower part of the pipe support (ST1) is filled with concrete or dried quartz sand (humidity not more than 2 "/, Fraction 0.62.0 mm) to the height of three pipe diameters after installation of the section pre-assembly (ST1, ST2 and ST3)

Supports ST1, ST2 and ST3 are connected by welding in factory conditions, and supports of sections ST3 and ST4 are connected by flanges on high-strength bolts M24 during installation of the spatial structure of the billboard ..

The support section of the tubular support (ST1) is designed with reinforcing stiffeners. The collected tubular support from sections CT1, ST2i has to CT3 L=22800mm on welding at design is checked for durability and stability taking into account its transportation and installation. In order to be able to install a tubular support from sections L = 22800mm during CMD development, it is necessary to provide a maintenance platform at an elevation of .21.14m for the possibility of flange connection between section CT3 and CT4. in addition, a running staircase to a height of 21.14 m should be provided with a hatch at the bottom of the maintenance platform at an elevation of .21.14 m.

Construction Site Organization

1. When performing works, be guided by the following requirements:

- SNiP 10032001 "Occupational safety in construction" Part 1 General requirements;

- SNiP 12042002 "Occupational Safety in Construction" Part 2 Construction;

- CH12-136-2002 "Decisions on labor protection and construction safety in projects of the organization of construction and

Work Execution Projects ";

- SNiP 3.03.0187 "Load-bearing and enclosing structures";

2. Provide fire safety measures at the construction site in accordance with the requirements of PPB0103.

3. The site fencing shall be made inventory, in accordance with GOST 2340778. The fence shall be installed no closer than the boundaries of the dangerous area of the installation cranes.

4. For temporary roads, use the existing coating and temporary coating of road slabs along a layer of crushed stone with a thickness of 0.1m, having previously removed the soil layer and performed sand preparation.

5. When entering the construction site, show the traffic pattern, warning and prohibiting signs..

6. Perform general lighting of the construction site with lighting not less than 2.0 lux. When working at night, illumination of production areas by the slave should be carried out using inventory portable towers with searchlights. At that illumination must be not less than 30 lux.

7. On the construction site, install fire shields painted red with inventory improvised fire extinguishing equipment: 1) ax - 3 pcs, 2) scrap, 3) shovel - 3 pcs, 4) bagor - 3 pcs, 5) fire extinguisher - 3 pcs. Place a box of sand and barrels of water near the shields. Domestic and storage rooms shall be provided with foam fire extinguishers .

The buildings under construction shall also contain primary fire extinguishing equipment. Prior to construction, locate the nearest existing fire hydrant (SG). On the fence of the platform, indicate the direction of the hydrant location with the distance to it with red paint.

Access of unauthorized persons to the construction site is not allowed.

Work areas, workplaces, driveways and passages to them in the dark shall be illuminated in accordance with GOST 12.1.04685. Work in unlit places is not allowed. Requirements for the lighting of workplaces are given on page 16 of this Project.

Driveways, passages and workplaces must be cleaned regularly, not cluttered, but located outside buildings, sprinkled with sand or slag in winter.

Warehousing of materials, structures and equipment shall be carried out in accordance with the requirements of standards or specifications for materials, products and equipment. Materials (structures, equipment) should be placed on leveled platforms, taking measures against their spontaneous displacement, drawdown, waking and rolling.

Workplaces and passages to them at a height of more than 1.3 m or more must be fenced. If it is impossible to arrange a fence, then work at height is carried out using safety belts. The place of attachment to strong supporting structures is determined by the manufacturer of the work. Operation from stairs is prohibited.

Noise protection

When performing construction and installation works on the construction site, follow the requirements of SNiP 23032003 "Noise Protection."

During the construction period, establish constant monitoring of the content of harmful substances in the air, as well as limit values ​ ​ of vibration and noise.

Work related to the use of construction machines such as excavators, bulldozers, cranes, compressor units, etc., should be carried out from 8.00 to 21.00 hours

Check of pipe axis verticality

Pipe axis verticality is a parameter that requires constant monitoring during installation and is performed sectionally with recording of data in the pipe verticality check log.

Geodetic survey is performed by theodolite from two points located on mutually perpendicular lines relative to the pipe design axis. The actual position of the pipe axis in the plane of the perpendicular line of sight is calculated from the points of the structure outline and does not require the placement of special signs. Based on the obtained data, the absolute deviation of the stack axis from its design position is calculated from two points of sight, and the necessary adjustments are made during installation.

Instrumental quality control of welds

Instrumentation during construction and installation works is performed in the following order:

Measuring inspection of welded joints - the dimensions of surface defects are controlled: the height and width of the weld, undercuts of the main metal, non-penetration of the outer and inner sides of the weld. During inspection, a set of tools for VIC is used.
