EVALUATION OF THE TECHNICAL STATE AND TASK OF RESTORATION OF THE OPERATING INDICATORS OF HYDROCONSTRUCTIONS OF RIVER RESERVOIR

Abstract

The results of the survey of the operational condition of the earth's water-retaining dam of the river reservoir with two single-span culvert bridges with unregulated water passage and recommendations for its restoration and maintenance of normal conditions of further exploitation are presented.

The earth’s water-retaining dam consists of two bridges, which are unregulated water passages from the reservoir, created in the upper reaches of the river Sluch by the installation of an earth dam, which crosses the main river bed with a width near 85 m and coastal flood plains. The dam is a continuation of the local dirt road, which connects two parts of the village of Kurchitsy, located on both sides of the river. Culvert slits are covered with span structures of pre-stressed reinforced concrete double-hollow plates according to the Typical Project 384/43 of Soyuzdorproekt. The supports of both bridges are massive pillars, which consist of stone masonry made of quarry-faced stones on a limy-sandy solution. Bridges are unfinished. The existing width of the span structures 6 and 7 m is not sufficient to form the dimensions in the locality (D-9+2×1.5m). Bridges need to be completed with the installation of the elements of the bridge cloth: sidewalks, security barriers, railings.
