Introduction

In increasing the efficiency of public production of our republic, an important role belongs to road transport, which can carry out road transportation and provide the necessary services to the population, provided that there is an extensive network of paved roads connecting all settlements, the structure and parameters of which must meet the increasing requirements of road traffic.

The primary task of road builders is to improve the organization and technology of construction processes, aimed at reducing construction time and improving the quality of work, finding not expensive, but providing high quality, local road construction materials: improving auxiliary production: further mechanization and automation of labor-intensive work.

The project for the organization of the reconstruction of the P95 "Lyntups - Svir - Smorgony - Krevo - Oshmyany" highway on the Krevo - Oshmyany section of the Smorgon and Oshmyany districts of the Grodno region with a length of 4.43 km was developed on the basis of a diploma design assignment and initial data for the project.

This section of the road is located in the Minsk region, connects settlements with each other and gives access to other roads of national economic importance.

The road provides transportation of agricultural, industrial goods and building materials.

Characteristics of the construction area. analysis of natural-climatic and economic conditions of the facility reconstruction

Technical and economic characteristics of the construction area

Roads are the most important part of the transport system, which largely determines the economic, social and cultural development of the Oshmyan region, which by its geographical location is located and borders with the Republic of Lithuania, the Volozhinsky district of the Minsk region; Ostrovets, Smorgon and Ivievsky districts of the Grodno region.

The road P95 Lyntupa - Svir - Smorgon - Krevo - Golshany is a republican road of category IV, passes through the territory of the Vitebsk, Minsk, Grodno regions, rich in historical, cultural and natural objects of great importance for the development of tourism in the Republic of Belarus. These include places of worship in the settlements of Lyntupa, Svir, Krevo, Boruny, Golshany, Narochansky National Park, Svir Lakes, Vishnevskoye. Almost throughout, the road has asphalt concrete pavement, except for the Krevo-Oshmyany section (km 100 - km 104.5) with gravel pavement, which is the object of reconstruction.

According to DRS190, the traffic intensity in the reconstructed area was 710 autos/day in 2004. According to the estimated forecast for the 10-year perspective, traffic intensity is expected in the amount of 1120 autos/day. According to the national economic value and estimated traffic intensity, the P95 highway on the reconstructed Krevo - Oshmyany section is classified as category IV.

Characteristics of longitudinal profile and soils along the route

The reconstructed section of the road is located in the southern part of the Oshmyan ridge. The thickness of the relief dissection is significant (0.8-1.0 km), the depth of the relief is 1015 m. The absolute elevations along the highway of the reconstructed road vary from 224 m to 260 m.

The terrain is characterized by large-hilly formations with a well-developed network of runoff lodges. The relief is formed by glacial flows and moraine deposits. There are no wetlands on the highway.

By the nature and degree of humidification according to SNiP 2.05.0285, the site belongs to the first type of terrain.

In the geological section along the road route, moraine deposits of the Sozhsky glaciation prevail on the reconstructed section, represented mainly by a light moraine loam of solid, semi-solid and refractory consistency, in the depressions of the relief with a dusty loam; small sand, dusty, light sandy sandy is found in separate nests. The thickness of the soil and vegetable layer is 0.20.3 m. The earth bed on the used section of the existing road on PK 1033 - PK 1044 is poured from medium, gravelly and sand-gravel mixture sand 0.20.3 m thick.

Groundwater lies deep and no wells up to 5 m deep are found.

In the general direction, the alignment coincides with the direction of the existing road. In plan, the route is designed with 14 angles of rotation. Fillet radii meet the requirements of SNiP 2.05.0285 for category IV roads.

To ensure road safety, it is envisaged to straighten tortuous sections of the road with an increase in rounding radii to 400600m, improve the road in the longitudinal profile with elimination of dips and increase in radii of convex vertical curves to at least 8000m.

The longitudinal profile is designed using spline vertical curves taking into account the geometric smoothness of the road, calculated visibility, the necessary elevation of the bottom of road clothing above the level of ground and surface water, ensuring the stability of the roadway and the strength of road clothing, as well as from the condition of snowiness.

The longitudinal profile in conditions of crossed terrain is designed in embankments up to 6 m high and excavations up to 4.5 m deep in the form of a geometrically planned spatial line linked to the road plan.

Maximum longitudinal slope 40% fr. Minimum radius of vertical curves: convex 8000 m, concave 4000 m.

The longitudinal profile is composed in absolute elevations. The route in high-altitude relation is fixed by temporary repositories with reference to the state non-leveling network.

To pass under the body of the embankment of water, reinforced concrete pipes are arranged at the following stations: PC 1003 + 40 diameter 1.0; PC 1009 + 71 diameter 0.75; PC 1012 + 12 diameter 0.75; PC 1014 + 30 diameter 0.75; PC 1026 + 45 diameter 1.0;

The design provides for the arrangement of extension of reinforced concrete culverts with a diameter of 1.0 m on PC 1019 + 49.

Provision of road construction materials, supply bases

For cargo transportation, the nearest road transport enterprise is the GAP13 of Oshmyany .

The distance of supply of vehicles from GAP13 to ABZ Zhuprana is 9 km, to the Soly station - 24 km, to the Boruna quarry 22 km, to the projected road - 25 km.

To transport workers to the place of work, it is planned to use their own transport.

The reconstruction of the P95 highway in the Krevo-Oshmyany section includes work on replacing worn and obsolete structures with more durable and economical ones, providing increased traffic safety and transport and operational performance of technical parameters for a higher category than that to which the road was assigned.

During reconstruction, separate sections of the road are built in a completely new direction, if their geometric elements do not meet construction standards for the category into which the road is transferred.

Earthwork and roadwear are being built, as in the new construction.

Great attention is paid to labor protection during construction work and environmental protection.
