2.1 Brief description of the natural conditions of the construction area

The construction site is located in Tyumen.

According to SNiP 230199 *, the territory in question belongs to the I climatic area, subarea D, which is characterized by the duration of the cold period of the year (with an average daily temperature below 00C) 190 days per year or more.

Climatic characteristics are given according to the weather station of Tyumen.

The climate of the area in question is sharply continental. It is formed under the influence of the western circulation of the atmosphere (cyclones) and the continent (anticyclones). There is a faster change of cyclones and anticyclones. The thermal regime depends on the penetration of temperate latitudes into the continent throughout the cold Arctic air and the removal of temperate latitudes (or even tropical air) from the south to the north of the heated continental air. The lack of security from the north and south contributes to free air exchange and meridial circulation, which contributes significantly to the pressure distribution and causes particularly sharp increases or decreases in temperature.

The climate in general form can be described as follows: severe long winters with long frosts and stable snow cover. Short summers and cool periods, late spring and early autumn frosts, short frost-free period.

The beginning of winter is characterized by great overcast, strong winds, large temperature fluctuations. Periods of relatively warm weather are replaced by severe frosts. In January and February, clear frosty weather prevails with fluctuations in the direction of wind and strong radiation cooling.

Spring is characterized by sunny unstable weather with increased wind. The increase in air temperature in spring is often interrupted by sharp cooling caused by the invasion of Arctic air masses. Frosts are observed until the end of May, and in some years until June. The duration of the spring period is 40 days.

Summer is warm, but short. A feature of this period are large reserves of solar heat and light. With the cessation of frosts, an intense increase in temperature occurs. July is the warmest month. In August, a noticeable decrease in temperature, cloudy days becomes more.

Autumn comes early, in duration it is twice as long as spring and warmer. Since September, temperature decreases with increasing intensity. In the second half of September, almost annually there are heat returns - "Indian summer." In October

very fast cooling occurs, frosty days become commonplace. In autumn, precipitation falls more than in spring. Precipitation falls mainly hard and mixed, snow cover is established, winter comes.

Climatic factors affect the assessment of the heat and moisture supply of the territory, determine the intensity of infiltration feeding of groundwater, characterize the current state of the territory.

The average monthly air temperature in Tyumen varies from 170C (January) to + 17.80C (July). Average annual air temperature + 0.70С. The coldest month of the year is January, the average January temperature is 170C. Absolute minimum 450C. In January and February, clear and frosty weather prevails. The annual absolute amplitude of the air temperature variation is 850C.

2.2 Main Plot Plan Solutions

The project provides for the implementation of the following zoning for the improvement of the territory:

a quiet recreation ground, a training and experimental ground, 4 playgrounds (by age gradation), a home farming ground, a gymnastics camp, a circular running track with a short distance and with a place for long jumping, a combined sports ground (football, volleyball), a basketball court, an obstacle course. On the sites, the relevant gaming equipment according to the Ugra catalog is installed by the manufacturer of Tobolsk, and the equipment according to the Algorithm catalog is installed by the manufacturer of Tyumen. Existing IAFs located in the school are subject to dismantling. Provide for uprooting of trees and shrubs falling into the territory of the designed sites (the need for the designed sites is prescribed in SanPIN 2.4.2.282110.

On the northern side of the school territory (in the side of the service entrance to the dining room opposite the house entrance) there is a garbage collection area (see sheet GP7 "Construction of the garbage area"), containers are located on it.

The school territory is protected by a fence of wrought-iron panels: supports (0-6) made of steel pipes with a height of 1,6 m and fencing panels OK10 (width .3 m) manufactured by Ugra OJSC (Tobolsk). All entrances are equipped with swing gates B1, and there are also wickets .

Road passage is made taking into account the requirements of the Technical Regulations on fire safety and convenient access to the school building and structures for economic maintenance and access of fire engines. To widen the existing passage, remove existing trees falling into the area of ​ ​ widening, with filling the pits with fertile soil (replacement with a live hedge is provided along the entire internal contour of the passage.

The vertical layout scheme is developed taking into account natural conditions, architectural, engineering and economic requirements.

The surface of the developed site is relatively flat. Discharge of storm and melt drains is provided surface along trays formed by a/road coating and concrete side-by-side, it is also provided by creating transverse and longitudinal slopes of the surface of the road surface and planned sections of the territory.

The terrain is calm. The slopes of the planned surface are taken 23 ‰. Taking into account the excess soil from the installation of a trough for road clothes of driveways, platforms and sidewalks, the mass haul balance is characterized by an excess of soil in the amount of 1683 m3. The intake of the missing fertile soil is 1026 m3.

Existing sidewalks and a/concrete passages shall be dismantled.

The coverage of the basketball court, mini-football field (with volleyball markings) and treadmill should be made of the Regupol injury-safe artificial coating (construction see GP5 sheet).

The coverage of the gymnastics camp is provided in the project of rubber mats (injury-safe coating, SibEkko Ave., Tyumen); playground and training-experimental platform made of trauma-safe special mixture (for design see GP5 sheet). Around the perimeter of the basketball and combined mini-football with volleyball markings of the court, a special one. grid for sports grounds with a height of 3 m. A quiet recreation area, a long jump landing pit and an obstacle course has a gravel-sand mixture coating (construction see GP5 sheet).

The area free from development, sites and coatings is sown with an herbal mixture (ordinary lawn) and vases for a flower garden are installed. On the central area of ​ ​ the school there are beds with a total area of ​ ​ 332 m2. Planting is provided: from shrubs - mountain ash, Hungarian lilac, and trees - common mountain ash. Adjacent lawns to the passage and sidewalks are landscaped by sowing seeds of perennial grasses with fertilizers and plant soil 0.15 m thick: red oatmeal - 60%, pasture district - 30%, white clover - 10%. There are also flowerbeds at the central entrance (list see GP5 sheet).
