Works related to the construction of new water reservoirs or adaptation of natural reservoirs include the following activities:
— wyznaczenie punktów sytuacyjno-wysokościowych,
— wykonanie robót ziemnych,
— ułożenie przewodów do doprowadzania i odprowadzania wody,
— wykonanie umocnień brzegów,
— umocnienie i uszczelnienie dna,
— wykonanie stanowisk dla roślin.
Situational and severity points are determined on the basis of technical and use projects. Especially accuracy requires the determination of the height points of the shore. Any field markings should be protected against damage. During earthworks, it is necessary to control the depths of excavations, because if they make them too deep, and then the backfilling of the land and the destruction of the made tank elements may occur.
Earthworks carried out during the construction of the tank usually consist in the excavation of the appropriate depth, corresponding to the depth of the tank and on the appropriate shaping of the ground surface for DNA strengthening. When conducting earthworks, it is necessary to maintain high accuracy in shaping the DNA surface and proper soil compaction.
Water supply cables should be laid after the earthworks are completed. After determining the place of deployment of wire outlets, the necessary strengthening should be made, and excavations for these cables should be covered with the ground, which should be sufficiently thickened.
Setting out the outlet cables in the shore line is quite easy and if it is not expected to create streams spilling above the water, The outlet of such cables can be placed below the water mirror. Work related to conducting wires formed in the middle of the tank water or fountains may be more complicated. This requires conducting wires in the excavation under the bottom of the tank and their proper deposition at the ejaculation site. Przewody takie powinny mieć spadki powrotne ‘umożliwiające opróżnienie ich z wody na okres zimy w razie opróżniania zbiornika.
Arranging the cable for emptying the tank from the lowest place located in the central part of the tank , requires the appropriate excavation. After laying the cable with the required decrease, the excavation should be covered, and the soil used for this purpose. Connections of overflow cables with cables for emptying the tank should be located on the open section.
