Strengthening the edges of the tanks: e), f), g) from prefabricated concrete elements, h) concrete wall.
Increasingly, the edges of natural and artificial reservoirs are strengthened with specially prepared concrete prefabricates. The advantage of these fortifications is above all very high, Durability and tightness and the possibility of significant mechanization of works related to their performance. Such elements also allow you to obtain a clear and equal line of the shore. Prefabricated elements are produced in two varieties: for natural tanks that do not require DNA sealing and for sealed tanks with various water -impermeable materials. They can have different sizes, the height of the wall forming the edge does not usually exceed 60 cm. The prefabricated foot also has a similar width. The length of the elements varies: Elements for building straight sections of the shore can be longer, However, the elements enabling the shaping of the curvilinear shore are short.
Before starting to set the elements, you need to make a trench, whose width should correspond to the width of the element of the element. The depth of the excavation should be such, so that it can be unfolded 10-15 cm of sand beds. The durability of prefabricated positions ensures the weight of the soil pressing the foot to the ground and the mutual connection of the elements with cement mortar.
The shore made of prefabricated concrete is a vertical wall protruding above the water mirror on 10-15 cm. Such strengthening, However, it is beneficial in terms of art, However, it is a difficult obstacle to the movement of various animals using water and going ashore. Therefore, it is necessary to take small breaks at such strengthening and use on these sections of mild ramps from other materials enabling animals to easily enter and leave it.
The discussed methods of strengthening the edges are used only then, when it is possible to keep water at a certain level. While the edges of the tanks, in which the water mirror level can be significantly fluctuated in strengthening in other ways. The most commonly used strengthening of such tanks is the paving of various types of stones. The gaps between the stones are usually inhabited by plants. Brzegs with larger slopes threatening the land of the soil are strengthened with stones on a special crushing foundation, podsypce cementowo-piaskowej lub też kamieniami o znacznych rozmiarach, Setting them deeply.
The surfaces of tanks with a variable level of water mirror are often lectured with various types of plates or concrete cubes. CDs can be prefabricated, and such is arranged with a crane, or made of concrete laid on site. In order to enable such vegetation to settle in such fortifications, plates or blocks with holes of different sizes are used.
