Additional information

2. Assessment of structural characteristics of a building or structure

The building under consideration, for which the foundations are designed, is a silo body with dimensions: width - 12 m, length - 48 m, height - 36 m, columns with a section of 400 × 400 mm are located with a pitch of 6 m and a span of 12 m. The building is not heated .

Nearby is a 2-story extension, which has dimensions: length - 12 m, width - 12 m,

height - 10.5 m. The building has a basement 2.2 m high.

3.3. Construction Site Report

According to the engineering and geological section, there are height differences of up to 2 meters on the construction site, the soils have a layered stratum .

The first layer: fine sand of medium density, medium degree of water saturation, medium bearing capacity with deformation modulus - can serve as a natural base.

The second layer: medium-sized sand loose, saturated with water, medium bearing capacity with a deformation modulus - can serve as a natural base.

Subsequent layers have a weak bearing capacity, so they cannot serve as a natural basis for laying foundations. Therefore, the foundation is arranged within the second layer of soil.

Any type of foundation can be used for construction on this site. Backfilling is performed by developed soil.

8. Zero Cycle Recommendations

The pit is developed by an excavator with a reverse shovel. Soil extracted from the pit should be placed at a distance of at least 0.5 m from the edge of the excavation.

According to [5], the selection of equipment for immersion of pile elements up to 25 m long should be made on the basis of the need to ensure the load capacity provided by the design of the foundation and the deepening of piles and pile shells into the soil at the specified design elevations. Additional measures facilitating the immersion of piles and tongue (washing, leader wells, etc.) should be applied in agreement with the design organization in case of failure of clogged elements less than 0.2 cm or vibration loading speed less than 5 cm/min.

At the beginning of piling works, 5-20 test piles (the number is set by the project) located at different points of the construction site should be clogged with recording of the number of impacts for each meter of immersion. The total number of impacts on the diving of the remaining piles is not counted. The measurement results shall be recorded in the work log.

Piles should be cleaned of ice, snow, frozen soil and fat stains before diving into wells. The piles shall be submerged within a time frame which excludes the flooding of the well walls, as a rule, not later than 4 hours after their grinding and acceptance.

The hanging piles are immersed in everlasting soils by drilling and driving method. The drilling-driven method of pile immersion is allowed to be used in plasticized soils without large-breaking inclusions. Piles are submerged by driving into pre-drilled wells with diameter of 1-2 cm less than the smallest size of pile cross section.

Reference finishing of piles after their freezing is not allowed.

Only piles with a continuous cross section should be submerged in a drill-driven manner.

Soil or special mortar should be poured into the well, as a rule, immediately before the pile is submerged. After pile immersion, compliance of the pile lower end elevation with the design elevation is checked, as well as correctness of pile location in plan and vertical.

Acceptance of the piles buried in soil and cut off at the design level, piles covers and the built protections of ditches (has to precede works on the device of grillages at their existence).

Foundations and pedestals are arranged on gravel and gravel preparation with a thickness of 100 mm. Concrete during pouring of foundations and pedestals is supplied by mixers with concrete mixture heating.
