THE ROLE OF GEODESY WORK IN THE DESIGN OF PUMP STATIONS

ABSTRACT

This article compares the benefits of using total station and traditional leveling methods for level surveying to create and update topographic plans in areas where waterworks are being built. These comparisons were evaluated on such items as preparatory work, picketing of the route, linking the route to the starting point, and leveling along the route axis.

АННОТАЦИЯ

В данной статье сравниваются преимущества использования электронных тахеометрических и традиционных нивелирных методов съемки уровня для создания и обновления топографических планов в районах, где строятся гидротехнические сооружения. Эти сравнения оценивались по таким пунктам, как подготовительные работы, пикетирование маршрута, привязка маршрута к начальной точке и нивелировка по оси маршрута.

Keywords: total station survey, leveling, tracing, survey, pump station, topographic survey, GPS-system.

Ключевые слова: тахеометрическая съемка, нивелировка, трассировка, съемка, насосная станция, топографическая съемка, GPS-система.

High yields of agricultural products largely depend on the reliable and uninterrupted operation of water facilities, including pumping stations. In recent years, great attention has been paid to improving the efficiency of water facilities and facilities. The efficiency of water facilities, including pumping stations, depends on their key performance indicators. Improving the efficiency of pumping stations, improving the design of its equipment and facilities, as well as the study of local conditions and factors that affect the efficiency of the machine-lifting complex, and the establishment of a system of scientific research.Nasos stansiyasini elementlarini joylashtirish, unumli ishlashini ta’minlash va ekspluatatsiya vaqtida foydalanishga qulay bo‘lishligi uchun quyidagi geodezik ishlar olib boriladi:

- Construction of planned and elevation geodetic substantiation (survey geodetic network) on the project area of the pump station;

- Topographic survey;

- Carrying out surface leveling and leveling works on the areas for vertical leveling;

- Creating plans (maps) and profiles;

- Drawing and design of linear structures, planning of elements of irrigation and drainage networks.

Geodetic works are of great importance in the implementation of geodetic works in the project area on the basis of the project at the level of demand.

In recent years, the introduction of modern automated tools and technologies in the field of geodesy in the design, construction and reconstruction of hydraulic structures in geodetic work and the development of results on a computer using special software, as well as graphic materials in a short time. It is known that a large amount of earthworks is carried out during the construction of collectors and drains, so the calculation of geodetic works on a modern electronic total station, and the volume of earthworks on the basis of a computer program, in turn increases productivity and saves time. causes. Therefore, we can compare traditional and modern leveling works (Figure 1,2).

Figure 1.perform measurements on an electronic total station

Figure 2. Leveling in the traditional way

From the above figures it can be seen that in the traditional method the levels have to be set at several points, while in a tacheometer we can focus from one point on all the characteristic points.

The descriptions of the time values spent for geodetic measurements performed in the area where the pump station is being designed, we consider Table 1 below to compare the results.

Results

From the data presented in the table, it can be seen that a number of theoretical and practical issues related to the study of the accuracy of topographic and geodetic works carried out in the design of the pumping station and the improvement of methods using GPS-systems and electronic taximeters have been addressed.

In conclusion, it should be noted that the use of modern geodesy instruments, including electronic total stations, when designing pumping stations that serve to improve the supply of irrigation water to agricultural land, not only creates great convenience, but also saves time (40-50%), reduces workforce and improve work efficiency. Therefore, we must pay special attention to these aspects when organizing the construction of water management facilities.
